The invention relates to the technical field of conveyor belt production equipment and processes, and provides a laminated conveyor belt four-roller calendaring device with welt rubber and covering rubber and a production process. A first gap is formed between a first bearing roller and a first forming roller, and a second gap is formed between the first forming roller and a second bearing roller; a third gap is formed between the second bearing roller and the second forming roller, and the sum of the thickness of the first gap and the thickness of the third gap is not smaller than the thickness of the second gap; a first forming groove is formed in the first forming roller; the output end of a first extrusion die head is arranged on one side of the first gap, and the width of the first extrusion die head is larger than that of a strip blank; the output end of a second extrusion die head is arranged on one side of the third gap, and the width of the second extrusion die head is larger than that of the first forming groove; and a cutter is arranged on one side of the second gap. By means of the technical scheme, the problems that in the prior art, a laminated conveying belt is low in forming efficiency and prone to disassemble and damage are solved.
Description
technical field [0001] The invention relates to the technical field of conveyor belt production equipment and technology, in particular to a four-roller calendering device and production process for a laminated conveyor belt with welt glue and cover glue. Background technique [0002] Conveyor belts are widely used in the transportation of materials in mining, wharf, electric power, chemical and other industries, and laminated conveyor belts account for more than half of the total use of conveyor belts. The traditional manufacturing method of the laminated conveyor belt includes the following steps: (1) prepare the mixed rubber for the calender fabric layer core glue, and the calender cover rubber material; (2) the purchased fabric core dipped canvas is calendered (3) After the molding process, the adhesive core layer is bonded in multiple layers and the covering film is pasted to form a belt blank; (4) The belt blank is vulcanized by heating and pressurizing the vulcanizer ...
