All conveyor belts must be connected in a loop to be operational, thus the quality of the belt joints significantly impacts the lifespan of the conveyor belt and the smooth, uninterrupted operation of the conveying equipment. Common methods for conveyor belt joints include mechanical joints, cold bonding joints, and hot vulcanizing joints.

Mechanical jointing method

Generally, this refers to the use of belt buckle joints, which are convenient and cost-effective. However, these joints have low efficiency and are prone to damage, impacting the service life of conveyor belt products. In PVC and PVG core flame-retardant antistatic conveyor belt joints, products with a tensile strength of 8 grades or below typically employ this jointing method.

Cold Adhesive Bonding Method

 The jointing method employs cold adhesive, which is more efficient and cost-effective than mechanical joints, and should yield good jointing results. However, in practice, the difficulty in mastering the process conditions, coupled with the significant impact of adhesive quality on the joints, makes it somewhat unstable.

Hot-Sulfur Curing Joint Method

Field experience has proven it to be an ideal connection method, ensuring high connection efficiency and excellent stability, with a long lifespan for the connections and ease of operation. However, it does have drawbacks such as complex procedures, high costs, and extended connection times.
