The length of a single coil of the conveying belt is generally hundreds of meters under production and transportation conditions, and one conveying line is often several kilometers to tens of kilometers, so that the conveying belts need to be spliced together on a conveying belt site, and the service life of the conveying belt and whether the conveying line can stably and smoothly run are directly influenced by the quality of a joint of the conveying belt. The strength at the conveyor belt joint is lower than the strength of a normal belt body. Generally, when the connection is carried out in a mechanical mode, the strength of the joint can only reach 40-50% of that of the belt body, when the quality of the cold glue mode 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 has no quality defects). Because the strength of the joint part is lower, if the gluing method is incorrect, the strength of the joint is lower, and a fracture accident is caused in the using process.
When the joint is made in a hot glue mode, a cutter is generally adopted to strip the rubber material at the joint layer by layer, the framework material is separated, then the framework material is spliced according to a specific splicing mode, and the specific rubber is coated on the upper part and the lower part of the framework material for hot-pressing vulcanization, and finally the high-strength conveyor belt joint is prepared. In the rubber stripping process, the prior art mostly depends on manual work, the art knife is held by hand, the rubber stripping process is separated layer by layer, the labor intensity is high, the consumed time is long, and people are frequently injured due to cracking of the art knife. Meanwhile, the requirement on personnel skills in the link is high, and if the rubber is not well stripped from the framework or the framework material is damaged, the joint strength is damaged. Therefore, a novel structure convenient for stripping the rubber framework is developed, the manual operation time is shortened, the operation safety is improved, the joint efficiency and the joint effect are greatly improved, and the novel structure has important significance.
