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 ...

The invention particularly relates to a high strength belt core for a conveying belt. The high strength belt core comprises an upper woven layer, an intermediate woven layer, a lower woven layer and an edge woven layer. The edge woven layer comprises the edge longitude lines and edge latitude lines. The edge longitude lines are woven alternately between every two adjacent layers in a mode of embracing the edge latitude lines; the span of the wave crest and the wave trough of up-down alternate weaving of the edge longitude lines is the 1-3 edge latitude lines; the number of the edge longitude lines is no less than 2, the edge longitude lines are aramid fibers, the number of strands of the aramid fibers is 6-16, and the degree of twist is 50-70 r / m; and the edge latitude lines are twine. According to the high strength belt core, aramid is adopted as the stress lines of the intermediate woven layer and the edge woven layer, longitudinal tensile strength is large, the abrasion-resistant strength of the edge is high, thus the high strength belt core can be used for the high-load conveying belt for long-distance transport, and the service life 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 ...
