Problems solved by technology

[0005] However, the problem of the joint strength of the straight conveyor belt has been difficult to solve
This means that under such ideal conditions, the strength of the existing straight conveyor belt finger joints can only reach 80% of the strength of the straight conveyor belt itself.

Abstract

The invention belongs to the technical field of a rubber conveyor belt product, and particularly relates to a straight conveyor belt finger-model connector and a preparation method thereof. The straight conveyor belt finger-model connector comprises a straight finger-model skeleton structure, wherein the straight finger-model skeleton structure comprises a straight canvas layer; a rubberizing layer is arranged on the surface of the straight finger-model skeleton structure; a textile layer playing a reinforcement effect is arranged on the rubberizing layer; and a coverage rubber layer is arranged on the textile layer. The preparation method of the straight conveyor belt finger-model connector comprises the following steps of (1) stripping coverage adhesive; (2) removing residual adhesive; (3) cutting a finger model; (4) coating adhesive cement; (5) splicing the finger model; (6) forming a finger-model connector; and (7) vulcanizing the finger-model connector. Due to the adoption of the straight conveyor belt finger-model connector, the strength of the connector is improved; and the preparation method is simple and easy to operate.

Description

technical field [0001] The invention belongs to the technical field of rubber conveyor belt products, and in particular relates to a straight conveyor belt finger joint and a preparation method thereof. Background technique [0002] At present, more and more ports, coal, steel, cement and other enterprises have increased the use of conveyor belts in order to improve production efficiency. At the same time, customers have higher and higher requirements for the strength specifications of conveyor belts. Ordinary plain weave canvas is bent up and down due to the warp. When the force is applied vertically and horizontally, part of the force is decomposed to the vertical direction. The higher the strength, the greater the bending degree of the warp and the greater the strength loss. Generally below 630N / mm. [0003] When customers need higher-strength belts, they can only increase the strength by lamination. When the multi-layer skeleton passes through the driving roller, due to...
