Description

Technical Field

[0001] This utility model relates to the field of conveyor belt technology, and in particular to a woven plastic-faced solid-core flame-retardant conveyor belt. Background Technology

[0002] Solid woven flame-retardant conveyor belts are mainly suitable for underground transportation in coal mines, and can also be used for material transportation in the metallurgical and chemical industries. Solid woven flame-retardant conveyor belts can be divided into PVC type and PVG type. In actual use, the core material and quality of PVG type conveyor belts directly affect the performance of the entire conveyor belt. Choosing different materials makes it easier to process conveyor belts of different strengths.

[0003] Chinese Patent Publication No. CN210001806U discloses a flame-retardant conveyor belt, comprising a lower cover rubber layer; an aramid skeleton layer disposed on the lower cover rubber layer; a buffer layer disposed on the aramid skeleton layer; and an upper cover rubber layer disposed on the buffer layer. The lower cover rubber layer, aramid skeleton layer, buffer layer, and upper cover rubber layer are all bonded together using a high-adhesion core adhesive. The aramid skeleton layer is made of straight-diameter, straight-weft aramid canvas. This invention, by selecting straight-diameter, straight-weft aramid canvas, can reduce the diameter of the drive roller and lower the motor drive power. The buffer layer can improve the conveyor belt's impact resistance, protect the skeleton layer, and extend the service life of the skeleton layer. The flame-retardant formula's main rubber compound is composed of natural rubber, styrene-butadiene rubber, and cis-butadiene rubber, solving the process problems of easy sticking to rollers, scorching, and short storage time when using neoprene rubber. The low rolling resistance flame-retardant lower cover rubber has low heat generation and low hysteresis loss, reducing the running resistance between the lower cover rubber and the idler rollers during conveyor belt operation and reducing energy consumption.

[0004] Traditional solid-woven flame-retardant conveyor belts use a split assembly structure, which is prone to detachment after assembly, affecting the relative stability of the conveyor belt connection. At the same time, internal displacement occurs within the conveyor belt, which also adversely affects the connection strength of the conveyor belt. Utility Model Content
