Joint of PVC conveyor belt: Due to the special structure of the whole core belt, the joint is not easy, so most adopt the mechanical joint method, that is, the belt buckle joint. However, in order to ensure the effect of joints, conveyor belts of grade 8 and above generally adopt the method of thermal vulcanization joints. The structure of the joints are finger joints. The thermal vulcanization joint process of PVC and PVG flame retardant conveyor belts is relatively complex, and the requirements for equipment are also relatively high. There are several common methods for conveyor belt joints: mechanical joints, cold bonding heads, and hot vulcanized joints. Mechanical joints generally refer to the use of belt buckle joints. This joint method is convenient, convenient, and relatively economical. However, the efficiency of the joint is low and it is easy to damage. In the joints of PVC and PVG whole core flame retardant antistatic conveyor belts, generally the products below grade 8 belt adopt this joint method. Cold bonding head, that is, using cold adhesive to make joints. This joint method is more efficient and economical than mechanical joints. It should have better joint effects, but from a practical point of view, because the process conditions are more difficult to master, the quality of the adhesive has a great impact on the joint. So it is not very stable. Hot vulcanized joints have proved to be the most ideal joint method in practice, which can ensure high joint efficiency, is also very stable, and has a long joint life, which is easy to master. However, there are disadvantages such as process trouble, high cost, and long joint time. Joint of layered PVC conveyor belt: You can use mechanical joints, cold bonding heads, hot vulcanized joints and other joint methods as needed. Generally, cold bonding heads and hot vulcanized joints adopt stepped structure joints.
