Problems solved by technology
Practice has shown that the service life of the conveyor belt is directly proportional to the thickness of the covering layer. In principle, the thicker the covering layer of the conveyor belt, the longer its service life. Since the covering layer of the whole core flame-retardant conveyor belt produced by the current technology is thinner, It wears out quickly during use. Once the covering layer is worn away, the overall belt core, which accounts for more than 90% of the production cost, loses its use value and must be replaced with a new entire core flame-retardant conveyor belt, so the service life is short, resulting in resources and energy consumption. waste

Embodiment Construction
[0011] The present invention will be described in detail below in conjunction with the accompanying drawings.
[0012] Under the traction of the four-roller main tractor (16), the integral tape core on the tape core sending device (1) enters the drying device (2), and enters the impregnation tank (4) after passing through the traction, cooling and hair removal device (3). ). The impregnation tank (4) is filled with polyvinyl chloride paste resin, and there are many sets of guide rollers arranged in it, and the whole belt core enters 1 through the guide rollers. # Vacuum box (5), 1 # The bottom of the vacuum box (5) communicates with the impregnation tank (4), and the upper part is connected with the vacuum pump, which is filled with polyvinyl chloride paste resin, and the whole belt core passes through 1 # The first vacuum impregnation is carried out in the vacuum box (5) and then through the mechanical oscillation device (6). The oscillating part of the mechanical oscillat...

Abstract
The invention provides a production line for a full-core inflaming retarding conveyor belt of a double-layer extruding veneering, which solves the problem of a conveying layer of a current conveyor belt is thinner. The production line comprises a belt core transmitter installation, a drier, a belt core dipping slot, a belt core plasticizing device, a double-layer veneering layer, a dragger, a recoiling machine, etc. The production line can be used for implementing double-layer extruding veneering; the produced covering layers can be composition of rubber and rubber, composition of plastic and plastic, composition of rubber and plastic, composition of rubber and thermoplastic elastomer, composition of plastic and thermoplastic elastomer, etc. The upper covering layer and the lower covering layer can be composition of same materials, and can also be composition of different materials; and the thickness of the conveying layers can be freely adjusted within a scope of 2-6mm.
Description
technical field [0001] The invention relates to a production line for a whole-core flame-retardant conveyor belt, more specifically, a production line for a double-layer extruded whole-core flame-retardant conveyor belt that can continuously produce double-layer covering layers and whose thickness can reach 6mm . Background technique [0002] The whole-core flame-retardant conveyor belt is the main tool for coal mines to transport coal. At present, there are two main production lines that can continuously produce the whole-core flame-retardant conveyor belt: one is the coating and scraping production line, which can produce plastic cores with a covering layer of less than 1mm. Flame-retardant conveyor belt; the other is the extrusion production line, which can produce plastic or rubber-surfaced whole-core flame-retardant conveyor belts with a covering layer of less than 3mm. Practice has shown that the service life of the conveyor belt is directly proportional to the thickn...
