Embodiment 1

[0025] A high-strength belt core for a conveyor belt, such as figure 1 , including an upper braided layer 1, a middle braided layer 2, a lower braided layer 3 and a side braided layer 4, the middle braided layer 2 is between the upper braided layer 1 and the lower braided layer 3, and the edge braided layer 4 is on the upper braided layer 1 , the sides of the middle braided layer 2 and the lower braided layer 3;

[0026] The upper braided layer 1 includes upper warp threads 11 and upper weft threads 12. The upper layer warp threads 11 alternately weave between adjacent two layers around the upper layer weft threads 12. The peak and trough spans of the upper layer warp threads 11 alternately weave up and down are 1-3 upper layer weft threads 12. , the upper layer warp thread 11 is polyester fiber, the number of shares of polyester fiber is 5 shares, the twist is 50-70 turns / meter, and the upper layer weft thread 12 is a ply thread;

[0027] The middle braided layer 2 includes ...

Abstract

The invention particularly relates to a high-tenacity belt core used for a conveying belt. The belt core comprises an upper woven layer, a middle woven layer, a lower woven layer and side woven layers. The side woven layers comprise side warps and side wefts. The side warps are alternately woven, surrounding the side wefts, between the adjacent two layers. The span of wave peaks and wave troughs of up-down alternate weaving of the side warps is 1-3 side wefts. The number of the side warps is at least two. The side warps are of aramid fibers. The number of strands of the aramid fibers is 6-16,and the degree of twist is 50-70 r / m. The side wefts are plied yarn. The belt core provided by the invention adopts aramid as the stressed yarn of the middle woven layer and the side woven layers, thelongitudinal tensile strength is large, the side abrasion resisting strength is high, the belt core can be used for the conveying belt for high-load and long-distance transportation, and the servicelife is prolonged.

Description

technical field [0001] The invention belongs to the field of conveyor belts, in particular to a high-strength belt core for conveyor belts. 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) discloses ...
