The design and manufacture of the belt joint of the conveyor belt vulcanizing machine, the design, the repair of the belt conveyor, the joint should take the form of layering, beveled, and stepped overlap. The number of overlapping layers X = Y-1, where Y is the number of nylon canvas layers inside the tape. In order to avoid cleaning the device when the tape is running, scraping the edge of the glued joint, the joint of the joint needs to consider the running direction of the tape, which may affect it, and cannot be reversed. After calculation, measurement, and marking, you can remove the extra rubber and canvas layers.
Since vulcanization requires heating and pressurization, and requires a relatively long time, after a relatively long time of vulcanization, the hardness of vulcanized rubber will increase, so the joint part will feel harder than other parts. The strength at the joint of the conveyor belt is lower than the strength of the normal belt body. Generally, when connected by mechanical means, the strength of the joint can only reach 40-50% of the strength of the belt. When the quality of the cold glue method is better, the strength of the joint can reach 60-70%, and the strength of the hot glue joint can reach 80- 90% (the joint method is correct and there are no quality defects). Because the strength of the joint is relatively low, if the method of bonding is incorrect, the strength of the joint will be even lower, such as cutting, hurting the next layer of cloth, excessive polishing, insufficient lap length, insufficient number of steps, adhesive joint The rubber used has poor performance or has failed self-sulfur, excessively polished wire rope, rusted wire rope, etc., the strength of the joint will be greatly reduced, and when used, it is easy to break the joint.
