How is the conveyor belt connected?


1. Method of joint: The method of joint of conveyor belt includes several common methods such as mechanical joint, cold joint and hot vulcanized joint. Mechanical joints generally refer to the use of belt buckle joints. This joint method is convenient and convenient, and economical, but the joints are low in efficiency and easily damaged, which has a certain impact on the service life of the conveyor belt products. In the PVC and PVG whole core flame retardant antistatic conveyor belt joints, the product is generally used in products with 8 or less belts. The cold bonding head, that is, the cold bonding adhesive is used for the joint. This joint method is more efficient and mechanical than the mechanical joint, and should have a better joint effect, but from the practical point of view, because the process conditions are difficult to master, the quality of the adhesive has a great influence on the joint. So it is not very stable. The hot vulcanized joint has proved to be the most ideal joint method, which can ensure high joint efficiency, is also very stable, and has a long joint life and is easy to grasp. However, there are disadvantages such as troublesome process, high cost, and long joint time.


2. Joints of layered conveyor belts: Joints such as mechanical joints, cold joints, and hot vulcanized joints can be used as needed. Generally, the cold bonding head and the hot vulcanized joint adopt a stepped structural joint.


3, PVC and PVG whole core flame retardant conveyor belt joint: Because the structure of the whole core belt is relatively special, the joint is not easy, so most of the mechanical joint method, that is, the belt buckle joint. However, in order to ensure the joint effect, the conveyor belt of grade 8 or higher generally uses a method of heat-curing joints. The structure of the joint is a finger joint. The hot vulcanization joint process of PVC and PVG whole core flame retardant conveyor belt is more complicated, and the requirements for equipment are relatively high.
