Problems solved by technology

[0002] In ore mining, rubber conveyor belts have been widely used to transport hard ores, but these ores are heavy and have sharp corners. When they fall on the conveyor belt, they have a serious impact on the conveyor belt, which can make the conveyor belt The rubber on the surface breaks and falls off, causing damage to the skeleton material of the conveyor belt and shortening the service life of the conveyor belt

Embodiment

[0025] Such as figure 1 As shown, a reinforced canvas for impact-resistant conveyor belts, the reinforced canvas is composed of several cyclic honeycomb unit structures, each unit structure includes several groups of warp and weft structures, and is formed by interweaving the warp and weft; The warp yarns include the first warp yarn a, the second warp yarn b, the third warp yarn c, the fourth warp yarn d, the fifth warp yarn e, the sixth warp yarn f and the seventh warp yarn g; the weft yarns include the first weft yarn 1, the second warp yarn Weft yarn 2, third weft yarn 3, fourth weft yarn 4, fifth weft yarn 5, sixth weft yarn 6 and seventh weft yarn 7.

[0026] The first warp yarn a is located above the first weft yarn 1, the second weft yarn 2, the third weft yarn 3, the fifth weft yarn 5, the sixth weft yarn 6 and the seventh weft yarn 7, and below the fourth weft yarn 4;

[0027] The second warp yarn b is located above the first weft yarn 1, the second weft yarn 2, the ...

Embodiment 2

[0036] Raw material: 1400dtex nylon 66 industrial filament, manufactured by Henan Shenma Group.

[0037] (1) Weaving: Twisting the above-mentioned nylon 66 industrial filaments, and then sending them through warping or creels, and weaving them into a canvas primary product including several honeycomb unit structures;

[0038] Warp yarn: 2 shares of 1400dtex nylon 66 industrial filaments are twisted after plying on a ring twisting machine. The twisting machine is R814 of Yichang Textile Machinery, the twisting degree is 120 twists / m, and the twisting direction is Z.

[0039] Weft yarn: Twist 3 shares of 1400dtex nylon 66 industrial filament on a ring twisting machine, the twisting machine is R814 of Yichang Textile Machinery, the twisting degree is 120 twists / m, and the twisting direction is Z;

[0040] Weaving: Creel let-off is adopted, warp yarns are placed on custom-made creels, warp let-off system outside the machine is adopted, Picanol OPTIMAX flexible rapier loom is used ...

Abstract

The invention relates to reinforcing canvas for an impact-resistant conveyor belt and a preparation method of the reinforcing canvas, and belongs to the technical field of industrial textiles. The reinforcing canvas comprises of a plurality of recycled honeycomb unit structures, each unit structure comprises a plurality of sets of warps and wefts, and the warps and wefts are interwoven to form thereinforcing canvas; the reinforcing canvas is prepared by weaving and gum dipping. According to the preparation method, black gum dipping is adopted to enable the color and luster of the reinforcingcanvas to be consistent with those of rubber, the impact force caused when a material falls on the surface of the conveyor belt can be buffered, the maximum stress on the rubber is reduced, the forcerange between the rubber and the material is expanded, the pressure at an impact point is reduced, the covered rubber on the working surface of the conveyor belt is protected, and the service life ofthe conveyor belt is prolonged.

Description

technical field [0001] The invention relates to a reinforced canvas for impact-resistant conveyor belts and a preparation method thereof, belonging to the technical field of industrial textiles. Background technique [0002] In ore mining, rubber conveyor belts have been widely used to transport hard ores, but these ores are heavy and have sharp corners. When they fall onto the conveyor belt, they have a serious impact on the conveyor belt, which can make the conveyor belt The rubber on the surface breaks and falls off, causing damage to the skeleton material of the conveyor belt and shortening the service life of the conveyor belt. In addition to improving the strength and impact resistance of rubber, you can also put a layer of body armor on the rubber to protect the rubber and the conveyor belt. Contents of the invention [0003] The purpose of the present invention is to overcome the above disadvantages, and provide a reinforced canvas for impact-resistant conveyor be...
