All conveyor belts must be connected in a circle shape before they can be used, so the quality of the conveyor belt joints directly affects the service life of the conveyor belt and the smooth operation of the conveyor line. Commonly used methods for conveyor belt joints include mechanical joints, cold-bonded joints, and hot vulcanized joints.
Mechanical joint method:
generally refers to the use of belt buckle joints. This joint method is convenient and economical, but the joints are low in efficiency and easy to damage, which has a certain effect on the service life of conveyor belt products. In PVC and PVG flame-retardant antistatic conveyor belt joints, generally, products below grade eight belts use this joint method.
Cold bonding method:
using cold bonding adhesive 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 control, and the quality of the adhesive has a great influence on the joint. So it is not very stable.
Hot vulcanization joint method:
Practice has proved to be the most ideal joint method, which can ensure high joint efficiency, and is also very stable. Joint life is also very long and easy to master. However, there are disadvantages such as troublesome process, high cost, and long joint time.
