Problems solved by technology
Most of the high-strength conveyor belts use steel cord rubber conveyor belts, and this kind of conveyor belt needs to use a large amount of metal materials—steel wire ropes, which not only increases the production cost and transportation cost due to its own weight, but also brings a lot of useless energy consumption during operation, resulting in unnecessary waste.

Embodiment Construction
[0014] The present invention will be further described below in conjunction with the accompanying drawings.
[0015] As shown in the drawings, the conveyor belt body 2 of the present invention includes an aramid rope core skeleton layer 1, a cover rubber layer 3, an aramid tear-proof net 4, an edge glue 5, and an intermediate glue layer 6; The fiber rope core skeleton layer 1 is formed by arranging several strands of aramid rope 11 at a certain distance, and is divided into different grades according to the strength and specification of the conveyor belt, and different grades use different rope diameters and different distances; the intermediate rubber layer 6 and The aramid rope 11 is combined, and the outermost layer is the covering rubber layer 3; there is an aramid tearproof net 4 between the upper middle rubber layer and the upper covering rubber layer, and there are side glue 5 with a certain thickness on both sides.
[0016] The aramid rope dipping, the glue is prepared...

The invention discloses a novel flame-retardant anti-tearing high-tenacity conveyor belt with aramid rope cores. By means of the conveyor belt, the problem that steel wire ropes are needed by existing conveyor belts is solved. The novel flame-retardant anti-tearing high-tenacity conveyor belt with the aramid rope cores is characterized in that a high-tenacity nonmetal fabric rope core framework is adopted, a middle rubber layer is combined with aramid ropes, a plurality of strands of aramid ropes are arranged to form an aramid rope core framework layer at certain intervals, and an anti-tearing aramid net is arranged between the middle rubber layer and a covering rubber layer; the aramid ropes are dipped in rubber, the rubber is prepared from a rope dipping rubber material and 120# gasoline with the proportion of 1 to 3, and formulas of the rope dipping rubber, middle rubber and covering rubber are provided. The steel wire ropes are replaced with the high-tenacity aramid rope framework, and therefore the weight of the conveyor belt can be greatly reduced, and consumption of metal materials is reduced; the conveyor belt is more effortless and convenient to use, the flexibility, the elasticity, the warping strength, the transverse tearing resistance and the usability of the conveyor belt are improved, and the service life of the conveyor belt is prolonged.
Description
technical field [0001] The invention relates to a conveyor belt of a conveyor, more specifically a new type of rubber conveyor belt with a high-strength fabric skeleton. Background technique [0002] Conveyor belt is one of the main components of belt conveyor, which is mainly used for large-scale and continuous transportation in sectors such as coal, mining, metallurgy, chemical industry, construction and transportation. The transported materials are lumpy, granular, powdery, pasty and finished items. At present, the following three types of conveyor belts are used at home and abroad. (1) Rubber layered belt: It uses cotton fabric or chemical fiber fabric to glue the tape layer as the belt core material, and uses rubber as the covering rubber material. (2) PVC / PVG whole-core flame-retardant conveyor belt: It uses vinylon-cotton blended fabric as the whole belt core, dipped in PVC paste and dried, and then covered with PVC / PVG material. (3) Steel cord conveyor belt: It us...
