Several Joint Methods of Conveyor Belt

With the rapid development of society, mechanized production has gradually replaced manual production, and conveyor belts are also welcomed by many manufacturers as the main means of transport for conveying materials or single items.

As long as it is a conveyor belt, it must be connected in a loop before it can be used, so the joint of the conveyor belt is a very critical link.

The quality of the joint directly affects the service life of the conveyor belt and whether the conveyor line can run smoothly. There are also many ways to connect conveyor belts. Today, I will introduce the difference between several commonly used conveyor belt joints:

Conveyor belt joint methods include: mechanical joints, cold bonded joints, hot vulcanized joints and other common methods.

1. Mechanical joint generally refers to the use of belt buckle joints. This joint method is convenient, quick and economical, but the efficiency of the joint is low and it is easy to damage, which has a certain impact on the service life of the conveyor belt. In PVC and PVG whole-core flame-retardant antistatic conveyor belt joints, generally products below grade 8 belts use this joint method.

2. Cold bonded joints, that is, cold adhesives are used for joints. This joint method is more efficient and economical than mechanical joints. It should have a better joint effect. However, from a practical point of view, because the process conditions are more difficult to grasp, and the quality of the adhesive has a great influence on the joint. So it is not very stable.

3. Thermal vulcanization joints have proved to be the most ideal joint method in practice, which can ensure a relatively high joint efficiency, and is also very stable. The joint life is also very long and easy to master. However, there are disadvantages such as troublesome process, high cost, and long joint operation time.

4. For the joints of the layered conveyor belt, mechanical joints, cold bonded joints, hot vulcanized joints and other joint methods can be adopted as required. Generally, cold bonded joints and hot vulcanized joints adopt stepped structure joints.

5. For the joints of PVC and PVG whole-core flame-retardant conveyor belts, the joints are not easy due to the special structure of the whole-core belts, so most of them use mechanical joints, that is, belt buckle joints. However, in order to ensure the joint effect of belts above grade 8, thermal vulcanization joints are generally used. The structure of the joints are all finger joints. The thermal vulcanization joint process of PVC and PVG whole-core flame-retardant conveyor belts is relatively complicated, and the requirements for equipment are relatively high.

 6. The joint of the steel cord conveyor belt is the most complicated of all conveyor belt joint technologies. Not only the process is more complicated, but the joint size parameters are also the most designed. Different types of products have different joint structures.
