Problems solved by technology

For example, in the process of food production and transmission, the traditional belt conveyor is prone to side hairiness during use, and it is easy to cause foreign matter to be mixed into the food product, and even pollute the entire production chain, thereby causing huge losses to production; in addition , in the tire industry, the conveyor belt used to transport the workpiece, due to the continuous friction during the transmission process, it is easy to produce more side hairiness, and these side hairiness are easily removed from the conveyor belt during the fast running of the conveyor belt. It will not only pollute the production environment, but also may fall into the raw rubber for tire manufacturing, which will greatly increase the risk of tire blowout in the final tire product, make the quality of the finished tire deteriorate, and cause immeasurable economic losses and reputation loss
[0003] The above problems fully expose the technical defect that the existing conveyor belt is prone to side hairiness during use
This is because the skeleton material of the traditional conveyor belt generally uses flat-woven PET (polyethylene terephthalate) filament fibers. There will be a lot of burrs, which will cause the wool around the belt to fall off during the process of conveying the product and mix into the product and cause pollution, eventually leading to irreversible product defects, causing serious quality problems, and bringing huge losses to manufacturers and customers. economic loss
[0004] In order to solve the above problems, the method often used at present is to do "edge sealing" on both sides of the conveyor belt, but the process conditions required by this method are relatively complicated, especially the "edge sealing" process of long-distance conveyor belts requires a long process. Time, and maintenance is also a big problem, which also greatly increases the processing and manufacturing cost of the conveyor belt

Abstract

The invention relates to a conveying belt capable of reducing lateral side fuzz amount generation. The conveying belt comprises a framework layer, a pasting layer and a covering surface layer, wherein the framework layer is formed by single-layer or double-layer fabrics, the pasting layer is arranged between the framework layer and the covering surface layer, the pasting layer and the covering surface layer are respectively made of thermoplastic elastic bodies, the conveying belt is pretreated through immersing the fabrics of the framework layer by polyurethane glue water, then, a coating process is adopted for sequentially coating the pasting layer and the covering surface layer onto the framework layer, and then, the conveying belt is prepared through heat treatment, rolling pressing and edge cutting. Compared with the prior art, the conveying belt prepared by the invention has the advantages that the wear-resistant performance is good, in the use process, the abrasion damage to the two sides of the conveying belt can be obviously reduced, and the generation of lateral side fuzz is effectively prevented, so the pollution to carrying and conveying objects in the production process can be reduced, meanwhile, the prepared conveying belt does not need the later stage processing edge sealing process, the production efficiency can be greatly improved, and good application prospects are realized.
