Industry knowledge

PVC conveyor belt is a very important part in the assembly line manufacturing factory, so the conveyor belt quality requirements are particularly strict. Most of the conveyor belt faults come from the interface. The interface is a point where problems easily occur. The conveyor belt interface is not well connected, which greatly affects the production efficiency, so the conveyor belt interface technology is particularly important here; The following describes the Mio conveyor belt manufacturers three conveyor belt interface mode.

1、 Lap joint

In the case of inconvenient disassembly of the machine, you can choose to lap, there are special conveyor belt processing also need to lap. Lap joint is layered by laminating machine, and then after special grinding treatment, with characteristics of glue sent to customers, customers can paste after receiving. The lap strength is about 75% of the rated tensile strength, and the thickness is consistent with the baseband.

2、 Toothed joint

Toothed joint is the most common joint of PVC conveyor belt, and it is also the most firm. PVC conveyor belt is layered first and then dented. Because the shape of teeth is the same after dented, it is called toothed joint. Toothed joint is a common joint method in the world. The tooth joint is fused by high temperature vulcanization of vulcanizing machine. After adhesion, the force on the joint is uniform. The thickness of the joint is consistent with that of the belt. The strength of the joint reaches about 90% of the rated tensile strength. Because of the high temperature fusion of the rubber surface, the toothed joint ensures the sanitation and easy cleaning of the conveyor belt.

3、 Steel buckle joint

Steel buckle joint is a kind of joint that can be disassembled repeatedly. Steel buckle joint has advantages and disadvantages. The advantages are that it can effectively avoid the inconvenient installation after the conveyor belt is looped. The disadvantages are that it is not easy to clean up, it is easy to breed bacteria, and it is easy to tear the conveyor belt joint slowly with long service life.

No matter which kind of joint is selected, the proper belt joint should be selected, which can not only effectively increase the service life of the belt, but also improve the production efficiency.

The broken belt joint is mainly affected by the following factors:

1. The tension is too large and the tension adjustment is too tight;

2. The conveying material exceeds the maximum load of the belt;

3. The running speed is too fast;

4. The conveyor belt is in bad environment and aging is accelerated;

5. Wrong selection of conveyor belt;

6. The conveying roller is too small, and the turning at the joint does not fit the roller;

7. The running time of conveyor belt is too long.

It is not only necessary to find out the cause of the fracture of the conveyor belt joint, but also to maintain the conveyor belt. It is suggested that you choose the joint mode reasonably, select the right type, maintain it in time, guard against aging and replace it in time.
