Structure of Modular Conveyor System

From the structure, it is very similar to the slat conveyor. The mattop conveyor includes below components, such as plastic modular belt, sprockets, wear strips, support parts, stands, frame material, motor and transmission mechanism. How does modular conveyor works? Firstly, the motor drives the sprockets. Then the sprockets make the modular conveyor belt to move on the wear strips.

The role of wear strips: firstly, it can increase the life of the modular conveyor chain. More importantly, during the mat top conveyor belt slides, friction will generate heat. However, wear strips can reduce the coefficient of friction. Thus, it can reduce the heat generation during transportation. Therefore, it reduces the thermal expansion and contraction of the plastic modular belt. So it can protect the modular conveyor chain well.

What is a modular conveyor belt?

Plastic modular belt is a very strong conveyor belt assembled from plastic modules. First of all, the plastic is thermoformed into semi-finished modules. Then assemble the modules into modular conveyor chain as requirements. Finally, install mattop conveyor chain on the conveyor to carry and transport materials.

Types of plastic modular conveyor belts

modular conveyor belt types

In order to adapt to various applications, there are a variety of mattop conveyor chains to choose from. Below are some main mat top conveyor belts.

1. The first is flat type conveyor belt. The conveying surface is flat and has no holes. It is suitable for applications where a fully enclosed conveyor surface is desired. So flat plastic modular belt can convey a wide variety of products. Moreover, it can ensure good conveying stability.

2. Second is the flush grid modular belt. The surface of the conveyor belt has strip-shaped grip holes. It is often used in applications that require drainage or air circulation. Due to the open-hole design, this kind of mattop conveyor chain has good air permeability. It can meet the requirements whether it is in high temperature steam or an environment that requires air convection. Moreover, the drainage performance is good. Therefore, it is also suitable for underwater operations. So there is no need to worry about the wet working environment causing the modular conveyor belt to slip.

3. Third is the anti-skid belt. There is rubber on the conveyor belt module. Or have non-slip texture. It is mainly used for the inclined modular conveyor or climbing conveyor. So it can prevent products from slipping during transportation. In addition, when apply for curve conveying, it can avoid the situation that the outer edge conveyor belt turns up from the outside to the inside.

Other mat top belt types:

4. Next is the modular conveyor belt with cleat and sidewall. The cleat is installed in the transverse middle of mattop conveyor belt. On the other hand, skirt sidewall is installed on the longitudinal side of the conveyor belt. The cleat and sidewall are higher than the belt surface to protect the material on the conveying surface. It has wide application in inclined modular conveyor or bucket elevator.

5. Fifth is a plastic modular belt with roller. There are movable beads / balls on the conveyor belt. It has a heavy load and low friction. Reduce noise. It facilitates better stacking and solves the problem of product retention. Besides, the sorting function is outstanding.

6. Finally it is the modular curve conveyor belt. There are two types of turning conveyor belts: horizontal and vertical splicing. Because plastic modules are very flexible, it can be directly made into modules of various sizes, shapes and angles according to the turning requirements. Then you can easily splice them into a cuved modular belt. In addition, it has also wide use in spiral conveyor.In addition, it has also wide use in spiral conveyor. The spiral modular conveyor can transport the goods up or down at a small incline angle. Therefore, there is no waste of space.

Features & Advantages of Modular Conveyor System

Due to the material and modular design of the conveyor belt, it brings many advantages. The most commonly used materials for modular conveyor belts are POM and PP. Sometimes it also use PE. Below are the advantages of modular slat chain conveyor.

  1. 1. Firstly, analysis of the characteristics of the plastic modular belt materials.

(1) POM plastic conveyor belt:

POM is namely Polyoxymethylene. It is an engineering plastic with excellent comprehensive properties. Above all, it has excellent properties such as fatigue resistance, wear resistance, heat resistance, and impact resistance. Moreover, the friction coefficient is small. In addition, the self-lubricating property is good. So the POM modular conveyor belt is firm and durable.

Secondly, POM has good solvent resistance. It is resistant to hydrocarbons, alcohols, aldehydes, ethers, gasoline, lubricating oil and weak alkalis. And it can maintain considerable chemical stability at high temperatures. Its temperature range is -40~90℃. In addition, the water absorption is small. Therefore, the dimensional stability is good in a humid environment. So POM mattop conveyor belt has good environmental adaptability. Moreover, POM belt can suitable for food.

However, POM plastic modular belt is not resistant to strong alkalis and oxidants. In addition, the weather resistance of POM is also not good. If it is exposed to ultraviolet light for a long time, the mechanical properties will decrease. The surface will crack.

  1. (2) PP modular conveyor belt

  2. The pp material is polypropylene. PP is a milky white highly crystalline polymer. It is non-toxic, odorless, and tasteless. Therefore, the PP plastic modular belt can directly contact food.

Its temperature range is +5~100℃. So PP mattop conveyor belt has good heat resistance. In addition, it is strong and rigid. Moreover, PP has excellent acid, alkali, salt, and alcohol tolerance. Besides, it is particularly stable to water. So PP modular conveyor belt can be used in water.

(3) PE mat top conveyor belt

PE material is polyethylene. It is odorless and non-toxic. Therefore, PE modular belts can also be suitable for food. Because of its excellent low temperature resistance, PE mattop belt is often used in slaughterhouses for refrigerated transportation. It temperature range is -70~+65℃.

In addition, the chemical stability is good. PE conveyor belt can withstand most acids and alkalis. Of course, it is not resistant to acids with oxidizing properties. Besides, PE is insoluble in general solvents at room temperature. And the water absorption is small. Excellent electrical insulation.

2. Other features of mattop conveyor

(1) Easy to maintain

Because plastic conveyor belt is resistant to oil and water, it is easy to maintain. Furthermore, it’s easy to clean. Therefore, the modular belt conveyor is particularly suitable for food and meat products. No matter what products to convey, such as pork, chicken, and fish, they will not be contaminated by blood and oil. It will not attach any impurities to the surface of the modular conveyor belt.

In addition, the plastic conveyor belt has good stability. And it has strong chemical resistance. So the modular conveyor system will not be damaged by detergent or hot water. Therefore, mattop conveyor is particularly suitable for the transportation of these products, such as fruits, vegetables, meat, seafood, baked products, frozen food, puffed food, etc.

(2) Easy to assemble, install and exchange

Conveyor belt modules can be easily combined. Because modular belt is spliced together, it is very convenient to install and disassemble. Moreover, it can supply the mat top conveyor belt in any length and width. If necessary, it can also add functional modules at any time. So it can meet some special conveying requirements.

If damage occurs, you can quickly replace individual belt modules. There is no need to replace the entire modular conveyor belt. Therefore, it can reduce the downtime and maintenance costs.

(3) Multiple conveying functions

Firstly, there are many types of plastic conveyor belts. Therefore, it can handle almost all conveying and processing tasks. Transport goods from light-load to heavy-duty transportation. The conveying range is very wide.

Moreover, modular conveyor system layout can be very diverse. Whether it is straight and turning conveying, or inclined and vertical conveying, it can meet the requirements.

Modular Belt Conveyor System Layout

modular belt conveyor system layout

The modular conveyor can be made into various shapes according to the layout requirements. The simplest is a straight mattop conveyor. Then next is the modular belt curve conveyor. It can be L-shape, U-shape, C-shape, S-shape and circular. Thirdly, when it needs to climbing transportation, we can customize the inclined modular conveyor. It can be Z-shape or straight incline (up or down). In the end, when the product needs to be temporarily stored or to cool down, it can be made into a spiral conveyor. Besides, it can also save the room space.

In addition, when needs sorting goods, it can customize the modular sortation conveyor. Moreover, it can design the diversion or confluence modular conveyor system.

Modular Mattop Conveyor VS Other Conveyor Machines

  1. 1. mat top conveyor vs tabletop conveyor

  2. Compared with table top chain conveyor, the structure and principle are the same. Due to the difference in the structure of the conveyor belt, the performance and application are different. The mat top conveyor belt is modular structure. Many mattop belt looks like mesh shape. Besides, there are lots of modular belt types and shapes. So modular conveyor system has wide applications from food to car tires.
  3. However, the tabletop conveyor belt is chain plate structure. It looks like slat or plate shape. Moreover, its types are less. Thus, it mainly convey the bottles, cans and cartons, etc.

2. modular curve conveyor vs PVC belt curved conveyor

Above all, the application range is much wider than that of PVC turning conveyor. Secondly, modular conveyor belt system is easiser to install and maintain. It is a bit difficult to assemble the belt curve conveyor. Moreover, when PVC belt damages, it needs to replace it totally. But the plastic modular belt doesn’t need to replace the whole belt.

Thirdly, sometimes the overall cost of the modular conveyor system is lower than that of a belt turning conveyor. For example, if it is S-shape, the belt conveyor needs to be composed of 2 sets of straight conveyors and 1 set of curve conveyor. Then it needs 3 sets of motors. However, modular conveyor system only needs one motor.

In addition, PVC belt conveyors often have the phenomenon of belt deviation. Of course, the load-bearing capacity of PVC belt conveyor is bigger.

How to assemble & install modular belt conveyor?

Before modular conveyor assembly, it needs to check all relative conveyor parts. Pay attention to the conditions of the support bars. Even if it is new. Make sure the surface is clean and flat. There must be no dust and other particles. Otherwise, it will significantly reduce the service life of the mat top conveyor belt.

If necessary, clean the plastic conveyor belt and other parts. At the same time, avoid dragging the conveyor belt on the dirty floor. In addition, verify the height between the support bar and the drive and idler. To ensure proper sprocket engagement.

  1. 1. Assemble the plastic modular belts

The modular conveyor belts are interlaced with each other in an interlocking or bricklaying manner. And then assemble the modules together by a long pin. In the end, use the head plug to fix the pin. Of course, when a customer buys a modular conveyor, the belts are all assembled well.

When installing the mattop conveyor chain onto the frame, place the conveyor belt on the support bar. Move the two conveyor belt ends until they can be properly connected. Then insert the pin. Finally, cut off the excess pin. According to this method, lay the modular belts on the conveyor frame.

When connecting the belts, make sure that they are not under tension. If applicable, allow a proper amount of modular belt sag between the buffer roller and the idler. So as to ensure the correct conveyor belt length. In addition, when installing the belt with sidewall, ensure that it runs in the correct direction.

2. Install the modular conveyor sprocket

The modular belt realizes the movement and guidance by the sprockets on the drive shaft or idler shaft. When using a sprocket to guide the alignment, the center sprocket must be firmly installed on the shaft with a positioning ring and a circlip. Of course, all other sprockets must be allowed to move freely on the shaft. So in the case of changes in operating temperature, it can adapt to changes in the width of the modular conveyor belt.

By fixing the central sprocket, it can ensure the even distribution of the expansion and contraction rate of the mattop conveyor belt. At the same time, it makes sure to align all the sprockets. Otherwise it will hinder the correct engagement of the sprocket and the modular belt.

The proper shaft size is particularly important for the lifetime of the modular conveyor belt. Excessive deflection of the drive shaft can cause improper meshing between the mat top belt and the sprocket. So it will speed up wear. This will also cause uneven force on the plastic conveyor belt. As a result, damage occurs, or the pin moves.

Troubleshooting of Modular Conveyor System

As an experienced modular belt conveyor manufacturer, we have summarized various solutions to problems.

  1. 1. The conveyor belt cannot be guided correctly. Besides, the edge touches the frame.

(1) Firstly, the sprocket may be misaligned
——If the total number of teeth of the square hole sprocket cannot be divisible by 4, the sprocket must be “corrected” by aligning the teeth.

(2) The position of the center sprocket is incorrect or loose
——The center sprocket must be aligned. It needs to be positioned in the center of the shaft and engaged with the modular conveyor belt. At the same time, check the fixtures. Make sure it is firmly fixed on the shaft.

(3) The conveyor belt bracket is uneven
——Check and adjust if necessary.

(4) Drive and idler shafts are not flush with each other
——Check and adjust if necessary.

(5) Two or more modular belts are partially misaligned. Besides, they are not connected properly. That is, the edges of the plastic conveyor belts are not straight.
——Check the uneven part of the mattop conveyor belt; then, re-align them.

2. Secondly, the conveyor sprocket does not mesh properly or fully

(1) The gap between the sprocket and the end of the support bar is too large
——Adjust the shaft position to achieve the recommended size.

(2) Sprockets are not aligned
——Check whether the axial position of the sprocket is aligned with the contact part of the plastic modular belt. And check whether the sprocket can move freely on the shaft.

(3) Insufficient tension of modular conveyor belt
——Ensure that there are enough overhangs to provide tension. You can use heavy hanging wheels to ensure tension.

(4) There is not enough mattop conveyor belt around the sprocket
——The mat top conveyor belt around the sprocket is between 180° and a minimum of 150°. To ensure a 180° wrapping angle, install a buffer roller or move the existing roller.

3. Thirdly, excessive wear of sprocket

(1) Not enough sprocket
——Too few sprocket will cause premature sprocket wear. So add conveyor sprockets if necessary.

(2) Sprockets are not aligned
——The solution is the same as above.

(3) Mattop conveyor belt speed is too high
——Excessive speed of the plastic conveyor belt will increase the wear of the sprocket. Especially for modular belts with a short center distance. Reduce the speed as much as possible.

(4) The modular conveyor belt tension is too high
——Excessive belt tension will increase sprocket wear. Make sure that there is an appropriate amount of catenary.

4. Fourth, excessive wear of the mattop conveyor chain

(1) The material of the mat top conveyor belt is incorrect
——Check the material specifications to ensure to use the best material.

(2) The support bar is set incorrectly
——Check that the support bar complies with the design instructions.

(3) Product loading
——If wear occurs when the product is loaded on the modular conveyor belt, if possible, reduce the distance between products and belt.

(4) Conveyor belt speed is too high
——Excessively high conveyor belt speed will increase its wear. Reduce the speed as much as possible.

(5) Too high load
——If the product weight is too heavy, it’s easy to damage the modular belt. Please ensure it meet load-bearing requirement.

5. Finally, the pin ran out of the plastic modular belt

(1) The pin is not locked correctly
——Check whether the pin head, the locking ring or the edge module of the mat top conveyor belt is damaged. Replace if necessary.

(2) The temperature causes the pin to stretch
——Choose the appropriate material of the bolt. Shorten the pin and reinstall it. Or replace with a new and shorter one.

Maintenance of Modular Belt Conveyor System

1. All plastic modular conveyor belts will stretch during the first few weeks of operation. This is normal and predictable.

2. After a period of use, it may need to shorten the mattop conveyor belt. In this case, it can adjust the winding mechanism. Or remove one or more rows of mat top conveyor belts.

3. If there are multiple modules on the entire width of the conveyor, after removing the excess conveyor belt length, confirm the integrity of the surface pattern of the conveyor belt. If the pattern is incomplete, remove a row of plastic conveyor belts. Or reinsert a row of modular belts.

4. After shortening the conveyor belt, ensure an appropriate number of overhangs on the return conveyor.

5. Check the modular conveyor belt regularly to make sure it is operating normally. Frequency of inspection depends on general operation conditions such as load, speed, actual wear, cleaning interval, operating temperature, etc.

6. It must replace damaged or worn parts to ensure trouble-free operation.
(1) Firstly, check the wear and alignment of modular conveyor sprocket.
(2) Secondly, check whether the plastic conveyor belt is tracking correctly.
(3) Thirdly, check whether the conveyor belt modules, cleatd and sidewall are damaged and worn.
(4) And then check the protruding pins of the modular belt.
(5) Finally, check whether the support bar/conveyor belt bracket of the conveyor is loose.

How to clean the plastic modular conveyor belts?

It is strongly recommended to clean the modular conveyor regularly. Cleaning can reduce overall wear of mattop conveyor belts, sprockets and pins. Thereby it will increase the service life of modular conveyor system.

The best cleaning method depends on the specific application and industry requirements. For example, the food processing industry is very demanding on hygiene and environmental requirements.

Of course, different modular belt materials have different chemical resistance. Therefore, before cleaning, please make sure to choose a suitable cleaning agent. When cleaning with hot water, do not exceed the maximum temperature allowed by the modular conveyor belt.

Do not exceed the recommended chemical concentration or exposure time of the cleaning agent. Especially high chemical concentration and high chlorine content can cause degradation of plastic materials. If in doubt about the suitability of the cleaning agent, please consult the cleaning solution supplier. After cleaning, always rinse the plastic conveyor belt thoroughly with water.

Factors affecting the service life of modular conveyor system

The maintenance of modular conveyor components, operating speed and load will affect the lifetime of the modular conveyor system.

1. Installation clearance
Be sure to leave enough space between the plastic conveyor belt, support bars, guide modules and other components. To avoid excessive wear. When determining the size, keep manufacturing and temperature changes in mind.

2. Alignment of support bars
For long-term worry-free operation, the alignment between the bracket and the modular belt must be accurate. This will avoid unnecessary resistance, pinch points and excessive wear.

3. Speed
We recommend that the soft start speed is faster than 20 m/min or more than 70% utilization. Keep in mind that the temperature increases with the increase in speed, and to ensure that the support bar will not be overloaded at high speeds.

4. Sprocket
We recommend that odd-numbered sprockets always use a center sprocket. Only fix the center sprocket and allow the other sprocket to move laterally. So as to cover the expansion of the modular conveyor belt width.

5. Expansion/contraction with temperature
When the temperature fluctuates, the plastic may expand or contract significantly. If the working temperature is different from the ambient temperature, the construction or design engineer must change the length and width of the modular belt. This will affect the mattop conveyor belt sag on the loop and the lateral gap on the conveyor frame.

6. Load
The weight of the product has a great influence on the life of the modular belt conveyor. When using, do not exceed the designed load capacity. It should start the modular conveyor system without load.

Plastic Modular Belt Conveyor Design

  1. 1. Mattop conveyor sprocket

During the slewing movement, the lifting of the module causes a change in the linear speed of the plastic modular belt. The number of teeth on the sprocket is the decisive factor for the periodic fluctuations of these speeds.

As the number of sprocket teeth increases, the percentage change in conveyor speed decreases. In practice, this means that if you do not want the goods to tip over or if it requires a more stable modular conveyor speed, it must use maximum number of teeth.

When confirming the correct number of sprocket teeth, please note that the larger the sprocket, the required transmission and shaft torque will increase accordingly. If the torque is too large, the sprocket teeth and the modular conveyor belt cannot mesh properly. It will lead to accelerated wear of the sprocket and plastic conveyor belt, or even damage. In addition, it may need to increase the shaft and motor power. This means an increase in costs.

About the return conveyor roller

Use an idler roller on the loop to ensure a wrap angle of approximately 180°. (This does not apply to mattop conveyor belts with a center distance of less than 2 m. It doesn’t require a roller on the return conveyor.)

Number of modular conveyor sprockets

According to experience, the sprocket spacing should not exceed 160 mm. Divide the width of the mat top conveyor belt by 150mm, round the result and add 1. Finally, get the minimum number of sprockets required.

If you end up with an even number, we recommend adding another sprocket to reach an odd number. So it can get a true center sprocket. However, narrow modular conveyor belts (<300 mm) are an exception. Here, mattop conveyor belt requires two sprockets. But there has never been a plastic conveyor belt with only one sprocket.

Depending on the load, it may need to increase the number of modular conveyor sprockets. And it can calculate number of drive sprockets from the adjusted ratio of the available belt tension.

2. The support system of modular chain conveyor

Standard plastic support bars are available from many plastic suppliers. The width should be about 30~40 mm. In addition, the thickness depends on the height of the screw head. We recommend using UHMD-PE or PE 1000 as the support bar of modular conveyor. Or, in some cases, it can use hardwood or steel. For the best choice of support bar material, see the table below.

Working Condition

(-40℃)

(+120℃)

Humidity, high abrasion or high temperature

Stainless steel (cold rolled austenite)
(Not recommended for soft annealed austenitic grades)

(-70℃)

(+155℃)

The continuous support plate is made of steel or plastic. We recommend it for heavy-duty conveyor belts. In addition, the layout of the support bars has two forms, namely parallel and V-shaped.

Linear parallel support bars are a low-cost solution for small load applications. If use parallel support bars, we recommend placing them between the sprockets to ensure support. The V-shaped type can make the support bar wear evenly. Thereby increasing the load of the modular belt conveyor.

For modular belt curve conveyor, it must support the sides around the curved part by plastic rails. The plastic can be is PE 1000 or a plastic with lubricating properties on the inner radius.

3. Modular Conveyor Shaft

The modular belt conveyor can choose not only square shaft but also round shaft. Of course, the square shaft has the following advantages over the round one.

(1) It can still be driven and tracked without machine keys and keyways. This can save manufacturing costs.

(2) Helps to move the conveyor sprockets horizontally under temperature changes.

Of course, circular shafts using guide keys are also suitable for narrow modular chain conveyor with low loads.

How to choose the modular conveyor shaft?

Choosing the right shaft size is particularly important for the lifetime of the modular conveyor system. Excessive deflection of the drive shaft can cause improper meshing between mattop conveyor chain and sprocket. Thereby accelerating wear. When selecting the shaft size, it should consider the bearing torque on the drive shaft. The tension of mat top conveyor belt transmits the torque to the drive shaft through the sprocket. Under the action of product load and frictional resistance, the tension of the modular conveyor belt will remain constant. However, the torque on the drive shaft will vary with the selected sprocket size.

Shaft alignment

Correctly aligning the shaft is conducive to the operation of the modular belt conveyor. Otherwise, it will cause the mat top belt to travel in the wrong direction. The mattop conveyor belt frame and shaft must be level. In addition, the shafts need to be placed correctly relative to each other. This means parallel alignment for straight conveyor belts. And vertical alignment for 90° modular curve conveyor.

Shaft bending

The drive shaft is bent due to the pulling force of the modular conveyor belt acting on it. This effect increases as the bearing distance increases and the shaft size decreases.

In order to reduce fatigue and ensure a small and uniform transmission gap, it should control shaft bending. We recommend that the deviation is less than 2 mm. If the belt tension causes a deviation of more than 2 mm, please choose a larger shaft. Especially for modular conveyor system with a wide belt width, install an intermediate bearing.

4. Design modular belt inclined conveyor

When design incline mattop conveyor, it should note the following aspects:

(1) The drive shaft must be located at the upper end of the conveying device. Or adopt a center-driven design.

(2) The slide rail support is preferred. Most incline modular conveyor system use cleats and sidewall. In these cases, it must use side rails.

(4) When the width of the mattop conveyor belt with a cleat exceeds 600mm, it should install a baffle for support.

(5) Suspension follows the same operating principle of horizontal modular belt conveyor. But in most cases, it is placed at the lower end of the conveying device.

(6) Because the inclined mattop conveyor is often used for heavy loads, the hanging chain may not provide enough tension to ensure the correct engagement of the drive sprocket. Therefore, it is best to install a screw-type tensioning device on the lower shaft.

5. Design modular belt curve conveyor

When the turning modular chain conveyor moves in a curve, it will exert pressure on the inner edge side guide rail. When designing, pay attention to the following principles:

(1) The turning radius should be as close to the minimum radius as possible. An excessively large radius will cause a frustration when the modular belt conveyor is running.

(2) In order to prevent the modular belt from turning over, it must add side guards to the inside & outside of the curve. However, if the width of the product is greater than the width of the plastic conveyor belt, it should use tab hook side guards. In addition, it generally use high molecular weight polyethylene with low friction coefficient.
