Problems solved by technology

During the use of the conveyor belt, when passing the driving roller, due to the different radius of curvature, the force of each layer of material is different, so the more layers of the conveyor belt, the more prone to delamination and the shorter the service life
The existing aramid conveyor belts all use aramid canvas as the skeleton material, and the number of layers of the conveyor belt is large, which is prone to delamination, and the bonding between the aramid canvas and the rubber layer is difficult

Embodiment 1

[0021] An integral belt core for a conveyor belt, comprising an upper braided layer, a middle braided layer and a lower braided layer. The middle braided layer is a one-layer structure in which aramid fibers are used as warp threads and ply threads of cotton yarn and polyester are used as weft threads. The upper braided layer is a one-layer structure made of polyester as the warp thread and the ply yarn of cotton yarn and polyester as the weft thread. The lower braided layer is a one-layer structure made of polyester as the warp thread and the ply yarn of cotton yarn and polyester as the weft thread.

Embodiment 2

[0023] An integral belt core for a conveyor belt includes an upper braided layer, a middle braided layer and a lower braided layer. The middle braided layer is a three-layer structure in which aramid fibers are used as warp threads and ply yarns of cotton yarn and nylon are used as weft threads. The upper braided layer is a one-layer structure made of nylon as warp and ply yarn of cotton yarn and nylon as weft. The lower braided layer is a one-layer structure made of nylon as the warp thread and the ply yarn of cotton yarn and nylon as the weft thread.

Embodiment 3

[0025] An integral belt core for a conveyor belt includes an upper braided layer, a middle braided layer and a lower braided layer. The middle braided layer is a two-layer structure in which aramid fibers are used as warp threads and ply threads of cotton yarn and polyester are used as weft threads. The upper braided layer is a two-layer structure made of nylon as warp and cotton yarn and nylon ply as weft. The lower weaving layer is a two-layer structure made of polyester as warp and ply yarn of cotton yarn and nylon as weft.

Abstract

The invention belongs to the field of conveying belts and particularly relates to an overall belt used for a conveying belt. The overall belt core comprises an upper knitted layer, a middle knitted layer and a lower knitted layer. The middle knitted layer is formed in a weaving manner with aramid serving as warp and stranded yarn serving as weft. The overall belt core used for the conveying belt has the beneficial effects that the cotton content is small, a belt body is light, and strength is high; the overall belt core can be used in the high-load conveying belt for long-distance transportation, and the comprehensive performance of the conveying belt is improved; the aramid is used as the middle knitted layer, the defect that the bonding performance of aramid fiber and covering glue is poor can be overcome, and the phenomenon that a covering layer is stripped from the belt core is avoided; and the overall belt core replaces multiple layers of canvas to serve as a conveying belt framework material, the number of layers of the framework material is reduced, the delaminating phenomenon of the conveying belt is avoided, and the service life is long.

Description

technical field [0001] The invention belongs to the field of conveyor belts, and in particular relates to an integral belt core for a conveyor belt. Background technique [0002] At present, the integral core conveyor belt products mainly include PVC integral core belt and PVG integral core belt. The thickness is too large, the amount of paste absorption is large, the thickness of the belt body after dipping is too thick, and the weight increases. At the same time, the comprehensive performance of the product such as fatigue resistance, wear resistance, and impact resistance is poor, and the service life is short. [0003] Aramid fiber is the strongest among the currently used organic fibers, and has the advantages of high temperature resistance, fire retardant, low density, low shrinkage, wear resistance, and chemical corrosion resistance. It is an ideal skeleton material for preparing high-performance conveyor belts. Wuxi Baotong Belt Industry Co., Ltd. (201210396203.8) d...
