Abstract

The utility model relates to a double-layer conveyer belt. The double-layer conveyer belt comprises an upper covering adhesive layer, a framework layer, a lower covering adhesive layer and three adhering layers, wherein the framework layer consists of two SW type canvas layers, namely, a first framework layer and a second framework layer; the three adhering layers are respectively a first adhering layer, a second adhering layer and a third adhering layer; the upper covering adhesive layer is adhered with the first framework layer through the first adhering layer; the lower covering adhesive layer is adhered with the second framework layer through the second adhering layer; the first framework layer is adhered with the second framework layer through the third adhering layer. According to the double-layer conveyer belt, the two high-strength SW type canvas layers are used as the conveyer belts of the framework layers and can be applied to the traditional fabric conveyer belt, so that the layers of the conveyer belt can be reduced, the weight of the whole conveyer belt is lowered down, the dynamic fatigue resistance of the conveyer belt is improved, and the tensioning stroke of the conveyer belt when in use can be decreased, and as a result, the double-layer conveyer belt can be used in a long distance under a wide range.

Description

A kind of double-deck conveyer belt

Technical field

The utility model relates to a kind of conveyer belt, is specifically related to a kind of double-deck conveyer belt.

Background technology

Along with scientific and technological progress, the progressively quickening that the energy uses, travelling speed and length progressively strengthen, transporting cargo progressively increases the weight of, each colliery, harbour, power plant, cement plant, the enterprises such as steel mill are selecting progressively to tend to high tensile wire rope conveyer belt on conveyer belt, and the desired driving power of high tensile wire rope conveyer belt and driving radius all need to strengthen, in addition belt of wire rope Heavy Weight, long-distance transportation need to provide larger drive energy, and conventional fabrics core belt, although there is some superiority in weight, but its framework material can not solve long distance, high running speed, the requirement of excess load service condition, therefore cannot replace the firm status of steel cord conveyor belt, for solving problems, JP is sent out SW type high-tenacity conveyer belt, such conveyer belt is called as " stone dead wire " conveyer belt, its flexibility is far longer than steel wire rope, its brute force is neighbour high tensile wire rope again, therefore aspect energy saving, there is unrivaled advantage, the conventional fabrics core conveyer belt number of plies is more, between every layer, all need to increase adhesive layer, and thickness is thicker, the number of plies is more, the force way difference that outermost layer canvas and innermost layer canvas produce when through driving roller is larger, internal layer is compress mode, stretching mode at outermost layer, time is when long, when running speed is fast, be easy to produce delamination between layers, and after conveyer belt delamination, be easy to cause conveyer belt wearing and tearing to aggravate, and then generation fracture, cause shutdown, produce huge economic loss.

Utility model content

Technical problem to be solved in the utility model is to provide a kind of delamination, double-deck conveyer belt of easy fracture not of being difficult for.

The technical scheme that the utility model solves the problems of the technologies described above is as follows: a kind of double-deck conveyer belt, comprise upper cover glue-line, casing play, lower cover glue-line, adhesive layer, described casing play is made up of two-layer SW type canvas, be respectively the first casing play, the second casing play, described adhesive layer is provided with three layers, be respectively the first adhesive layer, the second adhesive layer, the 3rd adhesive layer, described upper cover glue-line is bonding by the first adhesive layer and described the first casing play, described lower cover glue-line is bonding by the second adhesive layer and described the second casing play, described the first casing play and the second casing play are bonding by described the 3rd adhesive layer.

On the basis of technique scheme, the utility model can also do following improvement.

Further, the two-layer SW type canvas of described casing play is interwoven by warp and parallel, and on described warp direction and weft direction, changes the density of SW type canvas.

Further, the warp of the two-layer SW type canvas of described casing play is polyester material or aramid fiber material, and parallel is nylon 66 material.

Further, described the first adhesive layer, the second adhesive layer and the 3rd adhesive layer form by one deck adhesive glue.

Further, the brute force of the two-layer SW type canvas of described casing play is all greater than 800N/mm.

The beneficial effects of the utility model are: the utility model is by adopting double-layer high-strength power SW type canvas to be used on canvas core conveyor belt as casing play, can reduce the conveyer belt number of plies, alleviate conveyer belt overall weight, increase conveyer belt dynamic fatigue resistance energy, stroke of tension while reducing conveyer belt use, use therefore can grow distance, large width uses; On described warp direction and weft direction, can change the density of SW type canvas, thereby can adjust the bondline thickness between framework material, the rigidity requirement while making double-deck SW conveyer belt can meet traditional tape transport material, can meet again flexible requirement.
