Three Connection Methods for PVC/PU Conveyor Belt

The reason why the conveyor belt must be formed in an endless state is the specific application for transporting materials and products.

The conveyor belt connection area plays an important role in the whole process. First, production efficiency will be highly dependent on welding speed; secondly, the durability of the belt depends on the quality of the connection. Poor quality leads to underdelivery, which manifests itself, in particular, in the breakage of the joint of the conveyor belt. The reasons are as follows:

1. Frequent switching on and off of the conveyor equipment leads to a strong tension of the belts.
2. Poor quality of the belt at the junction of hot vulcanization. The strength of the connection drops with more than two times vulcanization.
3. The roller diameter of the equipment is too small to withstand the bending load when the belt moves.

If the conveyor belt breaks, there are three ways to help: Fasteners Mechanical connection, cold vulcanized joints and hot vulcanized joints. Each of them has its pros and cons.

1. Mechanical connection of fasteners, usually refers to the process of splicing with a rivet tool, fixture and fasteners such as wire hook, alligator fasteners, etc. This method is not only convenient but also economical.

However, there are also weaknesses. First, due to low welding efficiency and easy damage, the joint area has a short service life. In addition, there is little free space for cleaning in the connection area, so bacteria can easily multiply. Finally, the applicable equipment is limited. Therefore, this method can be chosen if the machine is difficult to disassemble. BELTWIN, however, offers a variety of fasteners such as Wire Hook Fastener, CX Series Fastener, LGK Series Fastener, Cross LGK Series Fastener, and MR Series Alligator Fastener.

2. Cold vulcanized joints is a method of joining tape with cold vulcanized material. which has higher efficiency and better quality than mechanical fastener connection. But the effect is unstable due to the difficult process conditions and the highly demanding cold vulcanized material.

3.Hot vulcanized joints, including layer separation process, tape finger perforation, high temperature bonding, etc., which is realized by heating and pressing, which is considered the best bonding method. This method makes the connection completely sealed and watertight, which contributes to the durability and stability of the tape. It takes more time to achieve the best splicing effect than the other two methods. For this splicing method, BELTWIN has several products, especially the air-cooled All in One. This product has many benefits. First, high work efficiency. Generally speaking, splicing can be completed within 12 minutes; secondly, there is no need for auxiliary equipment such as air pump, water pump, control box; thirdly, the equipment is portable. It is convenient for customers to use on site; Finally, environmentally friendly. Water treatment is not required.

Finger splicing literally makes the tape the same shape as a finger, which is the most common method for PVC conveyor belts. The finger joint is designed to vulcanize two conveyor belts of the same shape, which makes the joint area evenly loaded. Thus, the characteristic of easy cleaning is realized.

BELTWIN has all kinds of finger punching machines, such as manual finger punching machine. It has many benefits. First, there are no bandwidth limits. 600mm bandwidth can also be punched by TC300; Secondly, the equipment is portable. It is convenient for customers to use on site; thirdly, it is more economical than automatic tape puncher. In addition, you can make a “finger by finger” shape. What's more, various finger shapes and gripboards are available.
