Summary: The hot vulcanization jointing process for conveyor belts is essential because all conveyor belts must be joined to form a loop before they can be used. Therefore, the jointing of conveyor belts is a crucial preparatory step. The quality of the joint directly affects the service life of the conveyor belt and whether the conveyor line can run smoothly and steadily.

The hot vulcanization jointing process for conveyor belts is essential because all conveyor belts must be joined into a loop for practical use, making the joint a crucial preparatory step. The quality of the joint directly affects the service life of the conveyor belt and whether the conveyor line can run smoothly and steadily.

I. Joint Methods

Conveyor belt jointing methods include: mechanical joints, cold bonding joints, and hot vulcanization joints, among other commonly used methods.

II. 1. Mechanical Joints

Generally refers to using belt buckle joints. This method is convenient, quick, and economical, but the efficiency is low, it is easily damaged, and it has a certain impact on the service life of the conveyor belt product. In PVC and PVG solid core flame-retardant anti-static conveyor belt joints, products below grade 8 generally use this method.

2. Cold Bonding Joints

This involves using a cold bonding adhesive for joining. This method is more efficient and economical than mechanical joints and should provide better jointing results. However, in practice, due to the difficulty in mastering the process conditions and the significant impact of adhesive quality on the joint, it is not very stable.

3. Hot Vulcanization Joints

Practice has proven this to be the most ideal jointing method, ensuring high jointing efficiency, stability, and a long joint life, and is easy to master. However, it has drawbacks such as a complicated process, high cost, and long jointing time.

II. Joints for Multi-Ply Conveyor Belts

Mechanical joints, cold bonding joints, and hot vulcanization joints can be used as needed. Cold bonding joints and hot vulcanization joints generally adopt a stepped structure.

III. Joints for PVC and PVG Solid Core Flame-Retardant Conveyor Belts

Due to the special structure of solid core belts, jointing is difficult, so most use mechanical joints, i.e., belt buckle joints. However, for belts above grade 8, hot vulcanization joints are generally still used to ensure jointing quality. The joint structure is a finger-like joint. The hot vulcanization jointing process for PVC and PVG solid core flame-retardant conveyor belts is complex and requires advanced equipment.
