Why are conveyor belt joints easy to crack and disconnect?

The strength at the joint of the conveyor belt is lower than that of the normal belt body, which is generally connected mechanically The joint strength can only reach 50% - 70% of the belt strength (new buckle). When the cold glue method is of good quality, the joint strength can reach 60-75%, while the hot glue joint strength can reach 80% - 90% or more (the joint method is correct, without quality defects)

Because the strength of the joint is relatively low, if the bonding method is incorrect, the strength of the joint will be even lower. For example, the next layer of cloth will be damaged during cutting and grinding, the grinding is excessive, the lap length is not enough, the number of steps is not enough, the rubber used for the rubber joint has poor performance or has self sulfur failure, the steel wire rope is excessively polished, the steel wire is rusty, etc., the strength of the joint will be greatly reduced, and when it is used, It is easy to disconnect the connector

In addition, if the conveyor belt does not use sealing glue, or if the direction of the glue joint is wrong, the joint part is easy to crack (face glue part)
