The conveyor belt hot vulcanizing joint process is that all the conveyor belts must be connected in a ring shape to be used in practice, so the joint of the conveyor belt is a very important preparation step. The quality of the joint directly affects the service life of the conveyor belt and whether the conveyor line can run smoothly and smoothly.
1, the method of the joint
Conveyor joints include mechanical joints, cold bonded joints, and hot vulcanized joints.
Mechanical joints generally refer to the use of belt buckle joints. This joint method is 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.
Cold bonded joints are also cold bonded adhesives for joints. 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 relatively 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 operation time.
2. Joints of layered conveyor belts Joints such as mechanical joints, cold bonded joints, and hot vulcanized joints can be used as needed. Generally, the cold bonded joint and the hot vulcanized joint adopt a stepped structural joint.
3, PVC and PVG whole core flame retardant conveyor belt joints 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 belt of grade 8 or higher is generally a hot vulcanized joint. 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.
