All conveyor belts must be connected in a ring shape to be used, so the quality of the conveyor belt joints directly affects the service life of the conveyor belt and whether the conveyor line can run smoothly and smoothly. Common methods of conveyor belt joints include mechanical joints, cold bonded joints, and hot vulcanized joints.
conveyor belt mechanical joint method
Generally speaking, the belt buckle joint is used. This joint method is convenient and convenient, and economical, but the joint has low efficiency and is easy to be damaged, which has a certain influence on the service life of the conveyor belt product. In the PVC and PVG whole core flame-retardant antistatic conveyor belt joints, the products of the 8-stage belt or lower are generally used. The snap connection is equivalent to 28%-45% of the strength of the conveyor belt itself.
conveyor belt cold bonding head method
That is, a cold-adhesive adhesive is used for the joint. This joint method is more efficient and mechanical than the mechanical joint, and should be able to 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. Bonding with cold glue is equivalent to 40%-55% of the strength of the conveyor belt itself.
conveyor belt hot vulcanizing joint method
Practice 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. Bonding with mechanical heat vulcanization is equivalent to 60%-80% of the strength of the conveyor belt itself.
