Weaving framework for conveying belt

Abstract

The invention discloses a weaving framework for a conveying belt. The weaving framework comprises warp threads and weft threads, wherein the weft threads include upper-layer weft threads and lower-layer weft threads, the strand number of the warp threads is four, two strands of warp threads are alternatively woven with an uneven number of weft threads in the lower-layer weft threads and an even number of weft threads in the upper-layer weft threads in an opposite-direction mode, the other two strands of warp threads are alternatively woven with an uneven number of weft threads in the lower-layer weft threads and an even number of weft threads in the upper-layer weft threads in an opposite-direction mode, and two strands of warp threads are mutually staggered with the other two strands of warp threads to form a network. Compared with a framework structure in the prior art, the weaving framework for the conveying belt is higher in structural structure strength, the conveying belt including the framework can be connected by using the mode of a mechanical joint, is economic, convenient and quick, repeated calendaring and rubberizing in the conveying belt manufacturing process are not needed, the thickness of the conveying belt can be remarkably decreased, and the phenomenon that the conveying belt produces interlaminar glue failure after the joint forms an annular shape is avoided. The invention also discloses the conveying belt.

Description

technical field [0001] The invention relates to the technical field of conveyor belts, in particular to a braided framework for a conveyor belt and a conveyor belt. Background technique [0002] Conveyor belt is a rubber and fiber, metal composite product, or plastic and fabric composite product that carries and transports materials. Conveyor belts are widely used in cement, coking, metallurgy, chemical industry, steel and other industries where the conveying distance is short and the conveying volume is small. It affects the service life of the conveyor belt and whether the conveyor line can run smoothly. The common methods of conveyor belt joints mainly include mechanical joints and thermal vulcanized joints. Among them, mechanical joints generally refer to joints using belt buckles. This joint method is convenient and convenient. It is more economical, but the efficiency of joints is low and easy to be damaged, which has a certain impact on the service life of conveyor b...

Conveyor belts are widely used in cement, coking, metallurgy, chemical industry, steel and other industries where the conveying distance is short and the conveying volume is small. It affects the service life of the conveyor belt and whether the conveyor line can run smoothly. The common methods of conveyor belt joints mainly include mechanical joints and thermal vulcanized joints. Among them, mechanical joints generally refer to joints using belt buckles. This joint method is convenient and convenient. It is more economical, but the efficiency of joints is low and easy to be damaged, which has a certain impact on the service life of conveyor belt products, especially those with low strength; heat vulcanized joints are an ideal joint method, which can ensure high joint quality. Efficiency, but also relatively stable, the joint life is also very long, easy to master, but there are disadvantages such as troublesome process, high cost, long joint time, etc.

[0003] At present, the main material of the belt core skeleton of the general-purpose fabric core conveyor belt is polyester industrial filament and nylon filament woven into plain canvas. After dipping treatment, it is generally produced according to the 4-7 layer structure of calendering and pasting. The production process is complicated and the canvas needs to be adjusted. Apply glue 4-7 times. During the molding process, the uniformity of the force on each layer of canvas decreases, which is likely to cause a large loss of strength. The thickness of the core is thicker with more layers. Different radii will easily cause glue opening between each layer, and the cost is high

[0004] There is another SW type product with straight warp and straight weft structure, the structure is single layer or double layer, but because the warp is straight warp structure, the strength of the mechanical structure cannot meet the standard requirements, and it cannot be connected by mechanical joints. The connection between the conveyor belts is realized by means of hot-vulcanized joints
