Online rubber coating and repairing process of rubber layer of belt roller

Abstract

The invention discloses an online rubber coating and repairing process of a rubber layer of a belt roller. The rubber coating process comprises the following steps: a. enabling a component A and a component B of a polyurethane urea elastomer raw material to be sucked into a heating pipeline through corresponding suction pumps of a coating machine respectively, and starting a compression air source; b. carrying out sand blasting treatment on the belt roller and coating a bonding material; c. starting a belt roller motor and starting the suction pump and a spray gun, and enabling a spray gun head to be aligned with the surface of a rotating belt roller for spraying coated rubber, ensuring that the sprayed mixture is coated on the belt roller; and d. carving patterns on the rubber coated layer which is completely cured and formed. The repairing process comprises the steps of carrying out operations according to the process step a, then carrying out cutting, cleaning and modeling on defects of the belt roller, and operating the process steps of c and d, thereby obtaining a repaired finished product. According to the online rubber coating and repairing process of the rubber layer of the belt roller, the online coated rubber spraying and repairing operations can be realized, the service life of a product is long, the cost is low, and the online rubber coating and repairing process has good economical and social benefits.

Description

technical field [0001] The invention belongs to the technical field of chemical industry, and in particular relates to an on-line rubber covering and repairing process of a rubber layer of a belt roller. Background technique [0002] The belt roller is the rubber roller for the steering and tension of the conveyor belt, also called the head wheel and the tail wheel rubber roller. At present, the lagging of rollers mostly adopts two processes of traditional cold bonding and hot vulcanization. Among them, cold bonding is suitable for online lagging operations, and hot vulcanization can only be carried out in vulcanization workshops, which cannot meet online operations. [0003] In recent years, with the continuous improvement and improvement of polyurethane technology, equipment and technology, the use of new polyurethane urea spraying belt rollers to achieve online rubber covering, damage repair and other process technologies has brought technological innovation to the belt r...

Problems solved by technology

[0006] Disadvantages: 1. The performance of the adhesive is greatly affected by the price, the better the bonding performance, the more expensive the price; 2. The service life is greatly affected by the bonding quality and the use environment; 3. Degumming, delamination, After peeling and other defects, the destruction of the defects will be accelerated until the adhesive layer is scrapped, and the defect cannot be repaired online; 4. The adhesive tear resistance of the adhesive layer is small, and it is not suitable for large rollers, electric rollers, etc. 5. The overall service life is relatively long Low

[0009] Disadvantages: 1. The process route is long, there are many procedures and production equipment, and the operation is complicated; 2. The processing size of the roller is limited by the production equipment in the rubber workshop; 3. It cannot be operated on site and repaired online; 4. It is difficult to control the process and the yield is low. ,higher cost
