What is splicing/ jointing/ welding a belt?

Conveyor belt splicing/ jointing/ welding is the process of joining together two pieces of conveyor belt. Usually, this is done to either elongate the original conveyor belt or to repair a torn or damaged conveyor belt. There are three joint methods for rubber conveyor belts as follow.

How many ways are there for conveyor belt joints?There are three joint methods for rubber conveyor belts as follow.

Mechanical joint

Generally, it refers to the use of belt buckle joints. This joint method is convenient, convenient and economical, but the joints are inefficient and easy to damage, which has a certain impact on the service life of conveyor belt products. In the joints of PVC and PVG whole core flame retardant and antistatic conveyor belts, this joint method is generally used for products below grade 8 belts.

Conveyor belt cold jointing method

That is, the use of cold-bonded adhesives for joints. This joint method is more efficient and economical than mechanical joints, and should be able to achieve better joint effects. However, from a practical point of view, due to the difficulty in mastering the process conditions, and the quality of the adhesive has a great influence on the joints. So not very stable.

Conveyor belt hot vulcanization joint method

The conveyor belt joint has proved to be the most ideal joint method in many years of actual combat, 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.
