Modular Mesh BeltFactory briefTeflon Mesh BeltJoints of the introduction: all conveyor belts must be connected to the actual use of the ring, so the quality of the joints directly affect the service life of conveyor belts and the smooth flow of the conveyor can run smoothly.

The method of the joint

Polyester conveyor Belt joint methods are: mechanical joints, cold bonding joints, heat vulcanization joints, such as several commonly used methods.

1. Mechanical joints generally refers to the use of belt buckle joints, this joint method is convenient and efficient, but also more economical, but the efficiency of the joint is low, easy to damage, the conveyor belt products have a certain impact on the service life. In the PVC and PVG whole core flame-retardant antistatic conveyor belt Joint, the general 8-stage product adopts this joint method.

2. Cold bonding joint, that is, the use of cold adhesive adhesive for the joint. This joint method is more efficient than mechanical joints, but also relatively economic, should be able to have a better joint effect, but from the practice, due to the relatively rare process conditions, and the quality of the binder on the joint impact is very large, so not very stable.

3. Heat vulcanization joint, practice has proved to be the most ideal joint method, can ensure high joint efficiency, but also very stable, joint life is also very long, easy to master. But there are some disadvantages such as process trouble, high cost and long operation time of joint.

Second, the joint easy to crack, disconnect the reason

Polyester conveyor BeltThe strength of the joint is lower than that of the normal band. General mechanical connection, the strength of the joint can only reach the strength of the 40-50%, the quality of the cold glue is better, the joint strength can reach 60-70%, and hot glue joint strength can reach 80-90% (joint method correct, no quality defects). Because of the lower strength of the joint, if the bonding method is not correct, the strength of the joint will be lower, such as surgery, grinding injury and the next layer of cloth, grinding over, the length of the lap is not enough, the number of steps is not enough, rubber joints with poor performance or have since the sulfur failure, steel wire rope grinding, rust, steel wire rope, etc. The strength of the joint will be greatly reduced, when used, it is easy to appear the joint part of the phenomenon of disconnection.

In addition, if the polyester conveyor belt does not use the sealing gum, or the wrong direction of the glue joint, the joint site is prone to cracking.
