Anti-tearing steel wire rope core conveying belt

Abstract

The invention belongs to the field of conveying belts, and particularly relates to an anti-tearing steel wire rope core conveying belt. The anti-tearing steel wire rope core conveying belt comprises acovering layer, an intermediate layer, an adhesive glue layer and a steel wire rope; the intermediate layer comprises an upper intermediate layer body and a lower intermediate layer body which are each impregnated fiber cloth; the impregnated fiber cloth is made in the manner that fiber cloth is impregnated with covering rubber pulp; and the fiber cloth is formed by warp polyester silk and weft aramid fiber silk in a woven manner. The impregnated fiber cloth is added for the anti-tearing steel wire rope core conveying belt, the transverse stretching strength of the steel wire rope core conveying belt is improved, and the tearing phenomenon of the steel wire rope core conveying belt can be effectively prevented.

Description

technical field [0001] The invention belongs to the 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 by the adh...

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 aims 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 improves the resistance of the conveyor belt to scratches and tears, extending 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.
