7. The friction of the surface is moderate, the protection of the conveyed object is high, and it is not easy to stack and the conveyed object will not be damaged due to friction. Baffles can be added when used for climbing or transporting slippery or rolling objects.

8. The development space is large, and your modular belt conveyor system is not easy to be eliminated by the market. Because the characteristics of the modular belt depend on the characteristics of the polymer material that constitutes it, its development space is huge. For example, transmission solutions in industries with strong radiation and highly corrosive batteries such as radio frequency drying and microwave industries need to be realized through it.

Disadvantage:

1. Inability to deliver powder

2. The price is higher than the traditional conveyor belt

3. At present, there is no cost-effective plastic material to make the module belt in the high temperature field above 260℃

L (length), longitudinal unit of modular conveyor belt

1, the loading surface of the modular conveyor belt

2, The small end of the side block is assembled on the side of the modular conveyor belt

3, the middle block, assembled in the middle of the modular conveyor belt

4, The big end of the side block is assembled on the side of the modular conveyor belt

5. String strip, installed in the through hole after the module AB row crossed, used to connect the AB row modules in series

6, Plug, installed in the slot of the side block, used to fix the string

P (pitch), the center-to-center distance of the 2 through holes of the module

Through hole, the two through holes of the module are used to install the string in the hole when the AB row is assembled to form a belt in series

H (thickness), the thickness of the module

When assembled into a belt: usually consists of 2 side blocks small end, 3 middle block, 4 side block big end, 5 strings, 6 plugs, etc.; the module has 2 through holes for 5 strings; side blocks There is a slot on the side for installing 6 plugs, the purpose is to fix the string in the through hole of the block; when assembling: A row: 2+3*N+4; B row: 4+3*N+2 ; The reciprocating cycle of rows A and B is increased to the required L (length).

Note: N means that multiple blocks “3” (he middle block) meet the needs of W (width).

Plastic chain plate conveyor belt

It is also a new type of conveyor belt. The properties of this conveyor belt depend on the material of the modular belt, including plastic steel ACETAL, polypropylene, PP, polyethylene, PE, nylon, PA, and the most commonly used material is POM. In fact, international general models have been formed, and the matching is very simple. It is similar to the modular belt introduced above, the difference is that its width is fixed, it cannot be spliced horizontally, and the structure is simpler.
