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. Commonly used methods for conveyor belt joints include mechanical joints, cold-bonded joints, and hot-vulcanized joints.
Mechanical joint
Generally refers to the use of belt buckle joints. This joint method is convenient, convenient 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. The buckle connection is equivalent to 28%-45% of the strength of the conveyor belt itself.
Cold bonding head
That is, cold adhesive 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 master, and the quality of the adhesive has a great influence on the joint. So it is not very stable. Bonding with cold viscose is equivalent to 40%-55% of the strength of the conveyor belt itself.
Hot vulcanization joint
Practice has proved that it is the most ideal joint method, which can ensure 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 time. The mechanical thermal vulcanization bonding is equivalent to 60%-80% of the strength of the conveyor belt itself.
