Problems solved by technology

[0004] However, the structure of the single-layer skeleton layer of the aramid conveyor belt makes it difficult to adopt the traditional ladder lap joint method.
The German standard DIN22121 points out that "the joints of high-strength single-layer or double-layer fabric core conveyor belts are connected by finger splicing." There are few domestic studies and reports on finger joints of aramid conveyor belts.
However, due to the discontinuity of the skeleton material in the form of finger splicing, the strength of the joint depends entirely on the strength of the rubber body and the shear strength of the bonding interface. It does not take advantage of the high strength and high modulus of the aramid canvas skeleton material, and the joint strength retention rate is low.

Embodiment 1

[0034] Such as Figure 1-3 Shown: A high-strength single-layer aramid conveyor belt joint structure, including a single-layer aramid straight warp and straight weft canvas conveyor belt, the single layer aramid straight warp and straight weft canvas conveyor belt consists of a skeleton material in the middle and covers the upper and lower The two ends of the upper belt body cover glue and the lower belt body cover glue; the two ends of the skeleton material of the single-layer aramid straight warp and straight weft canvas conveyor belt are spliced ​​with each other to form a ring; the upper and lower sides of the skeleton material are covered with a layer cladding;

[0035] The cladding layer sequentially includes a cover film, a first adhesive layer, a fabric reinforcement layer and a second adhesive layer from top to bottom; the second adhesive layer is directly bonded to the skeleton material; The splicing of the skeleton material of the straight weft canvas conveyor belt ...

Embodiment 2

[0045] The preparation method of the high-strength single-layer aramid conveyor belt joint structure, the steps are:

[0046] (1) Peel off the rubber material: take the single-layer aramid straight warp and straight weft canvas conveyor belt to be connected, and peel off the upper belt body covering glue and the lower belt body covering glue in the joint area at both ends; the remaining upper belt body covering after stripping Trim the end surface of the glue and the covering glue of the lower belt body into a 45° groove, and the slope width is 50mm; cut off the remaining glue on the surface of the skeleton material, and pay attention to avoid scratching the canvas surface of the skeleton material;

[0047] (2) Grinding excess glue: Grind the surface of the single-layer aramid straight warp and straight weft canvas conveyor belt skeleton material obtained in step (1) with glue, and pay attention to avoid damage to the surface of the skeleton material to prevent polishing or sco...

Abstract

The invention relates to a joint structure of a high-strength single-layer aramid fiber conveyor belt and a preparation method thereof, belonging to the technical field of rubber conveyor belt products. It includes a single-layer aramid straight-warp and straight-weft canvas conveyor belt. The straight-warp and straight-weft aramid canvas skeleton materials in the joint areas at both ends of the single-layer aramid straight-warp and straight-weft canvas conveyor belt are meshed and spliced ​​with each other. The upper and lower sides of the canvas skeleton material are respectively covered with a layer of adhesive layer, and the fabric is placed on the adhesive layer as a reinforcement layer, and a layer of adhesive adhesive for bonding is covered on the reinforcement layer, and then the upper and lower covering adhesive layers are bonded into a One-piece; High-strength single-layer aramid conveyor belt joints are obtained by stripping rubber, grinding excess glue, cutting fingers, cutting fabric reinforcement layers, painting glue, splicing fingers, forming joints and vulcanized joints. The product prepared by the invention has a good joint strength retention rate, and can also meet the requirements of the single-layer aramid conveyor belt on dynamic flex performance, and the preparation method is simple, economical and practical.

Description

technical field [0001] The invention relates to a high-strength single-layer aramid conveyor belt joint structure and a preparation method thereof. The obtained product has a good joint strength retention rate and can also meet the dynamic flexural performance requirements of the single-layer aramid conveyor belt. The invention belongs to the technical field of rubber conveyor belt products. Background technique [0002] In recent years, the rapid development of the national economy has catalyzed the continuous expansion of steel, cement and other manufacturing industries and the continuous improvement of production capacity, which has brought greater opportunities and challenges to the material conveyor belt industry. Customers have continuously improved the strength specifications of the conveyor belt, but ordinary plain canvas adopts the method of lamination to increase the strength. When the belt body passes through the driving roller, the difference in the curvature rad...
