Problems solved by technology

Nevertheless, the cold bonding method also has deficiencies, that is, there are still seams on the front, back and both sides of the joint. Due to the stress concentration, especially under the combined action of water and corrosive substances, the tape seams are very easy to warp or be damaged. Scraping and aggravated corrosion cause a large area of ​​seams to be glued and the belt to be delaminated, eventually resulting in frequent damage to the belt, the belt conveyor cannot be operated, and the material transportation cannot be carried out

Abstract

The invention provides a method for bonding seamless joints of a rubber conveying belt and relates to a connecting method for rubber belt joints of a belt conveyor. The joint bonding process comprises the following steps: (1) determining an overlapping length of the joints; (2) measuring and marking; (3) cutting; (4) raking the joints; (5) polishing, cleaning, washing and drying; (6) brushing glues; (7) drying; and (8) laminating and hammering; and the seamless jointing method is characterized in that jointing process further comprises the following steps: (9) polishing a sealing reinforced strip recess in a seamless joint of the rubber conveying belt; (10) brushing glues to the recess; (11) putting a sealing reinforced strip into the sealing reinforced strip recess and hammering the sealing reinforced strip; and (12) curing the rubber conveying belt and putting the rubber conveying belt in use. Through the adoption of the method provided by the invention, the traditional joint bonding method is perfected and improved, a very good effect is obtained especially under severe working conditions, and a seamless reinforced rapid bonding joint is formed.

Description

technical field [0001] A rubber conveyor belt seamless joint method relates to a belt conveyor belt joint connection method. Background technique [0002] Belt conveyors are widely used in various industrial and mining enterprises. The operation of conveying materials is simple, flexible and fast, and has the characteristics of low maintenance costs and high efficiency. The value of the rubber conveyor belt generally accounts for 40% of the total price of the conveyor. During the production and operation process, the belt is damaged due to fatigue, wear and some external factors, which will cause degumming, opening, tearing, and breaking. Whether the quality of the joint is good or bad directly affects the service life, which is especially important to ensure the normal operation of the equipment. [0003] Rubber belt connection methods can generally be divided into two categories: mechanical connection and glued connection. Mechanical connections mainly include metal belt...
