Anti-tearing steel wire rope core conveying belt

Abstract

The invention particularly relates to an anti-tearing steel wire rope core conveying belt comprising covering layers, anti-tearing layers, an intermediate layer and an edge glue layer. The anti-tearing layers comprise the upper anti-tearing layer and the lower anti-tearing layer, the upper anti-tearing layer is arranged on the intermediate layer, and the lower anti-tearing layer is arranged underthe intermediate layer; the anti-tearing layers are glue dipped fiber cloths, the glue dipped fiber cloths are made in the mode that fiber cloths are dipped in covering glue, and the fiber cloths aremade by weaving polyester silk serving as longitude lines and latitude lines; the covering layers comprise the upper covering layer and the lower covering layer; a layer of non-woven cloth is arrangedon the upper covering layer; and the edge glue layer comprises aramid short fibers, adhesives and covering glue. According to the anti-tearing steel wire rope core conveying belt, the tearing phenomenon of the steel wire rope core conveying belt can be prevented, the rigid strength and the anti-tearing property of the edge glue layer are good, and bubbles are not liable to be generated in the manufacturing process, so that the repair workload is reduced, and the product quality is improved.

Description

technical field [0001] The invention belongs to the technical field of conveyor belts, in particular to a tear-resistant steel cord conveyor belt. Background technique [0002] Steel cord conveyor belt is a kind of rubber conveyor belt, because of its high longitudinal tensile strength, small elongation, good troughability, and good flex resistance, it is suitable for long-distance, long-distance, and high-speed conveying materials. [0003] Most of the steel cord conveyor belts currently available in the market are produced according to GB / T9770-2001 or MT668-2008 standards. Its structure is that the number and type of steel cords specified in the standard are arranged longitudinally at a certain distance, and they are pressed and wrapped with adhesive glue. The top is covered with a working surface rubber layer, and the bottom is covered with a non-working surface rubber layer, which are bonded together by vulcanization. Because the horizontal direction is only connected ...

AI Technical Summary

Problems solved by technology

Because the horizontal direction is only connected by the adhesive layer, the tensile strength is low. When the conveyor belt encounters harsh working environments such as the impact of large materials on the surface of the belt or the puncture of sharp materials, surface damage or longitudinal tearing occurs from time to time. The entire conveyor belt is scrapped immediately, and the service life is low, causing serious economic losses to the production of the enterprise

[0004] Chinese invention patent CN201907820U has been aimed at the problem of poor scratch resistance and tear resistance of steel cord conveyor belts, and discloses a steel cord conveyor belt with transverse or oblique reinforcement. The network structure formed in the belt improves the resistance to scratches and tears of the conveyor belt and prolongs the service life of the conveyor belt

However, adding transverse or oblique reinforcement to the steel cord conveyor belt will increase the thickness and self-weight of the conveyor belt, which will affect the grooving and flex resistance of the steel cord conveyor belt.
