Problems solved by technology

This kind of production method must make the canvas 30-40mm wider than the specified size, and the width of the canvas with the blank and the blank must be the same, and then trim the edge after the treatment, which will cause a lot of waste of rubber and increase the trimming. The process increases the input of human and physical resources and increases the production cost

Embodiment 1

[0011] The non-cutting production process of the canvas core conveyor belt described in this embodiment, the first step is to process the canvas to produce a canvas that is 10mm wider than the specified size of the canvas core of the conveyor belt. The raw edges on both sides are treated with high-temperature ironing, so that the width of the canvas can meet the size requirements of the conveyor belt.

[0012] The second step is gluing and forming. Lay the canvas that has reached the specified width and the conveyor belt film of the same width at intervals. The thickness of the outermost film is greater than the thickness of the inner film.

[0013] The third step is vulcanization. The formed conveyor belt blank is vulcanized into a conveyor belt through a vulcanization system.

[0014] The fourth step is to cool, roll up and pack, roll up the vulcanized conveyor belt with a winder after cooling, and fix it.

Embodiment 2

[0016] The non-cutting production process of the canvas core conveyor belt described in this embodiment, the first step is to process the canvas to produce a canvas that is 20mm wider than the specified size of the canvas core of the conveyor belt. The raw edges on both sides are treated with high-temperature ironing, so that the width of the canvas can meet the size requirements of the conveyor belt.

[0017] The second step is gluing and forming. Lay the canvas that has reached the specified width and the conveyor belt film of the same width at intervals. The thickness of the outermost film is greater than the thickness of the inner film.

[0018] The third step is vulcanization. The formed conveyor belt blank is vulcanized into a conveyor belt through a vulcanization system.

[0019] The fourth step is to cool, roll up and pack, roll up the vulcanized conveyor belt with a winder after cooling, and fix it.

Abstract

The invention designs a non-trimming production process of a canvas core conveyor belt. The process comprises the following steps: firstly, treating canvas, producing the canvas that is 10-20 mm wider than a given size, performing the immersion treatment on the canvas, and performing the high-temperature edge-ironing treatment on rough edges at two sides of the canvas through a high-temperature edge-ironing machine so that the wide size of the canvas reaches the size requirement of a conveyor belt; secondly, rubberizing, forming, sticking the canvas and the film of the conveyor belt with a space reserved; thirdly, vulcanizing a formed conveyor belt billet to form the conveyor belt through a vulcanization system; fourthly, cooling, rolling up and packaging. The non-trimming production process of the canvas core can perform the high-temperature edge-ironing on the canvas so that the canvas has the given size, then the conveyor belt is directly produced to the given size; therefore, the trimming process of the conveyor belt is omitted, the investment in the production line and the production device is reduced, and the labor force is saved, and the production cost of the conveyor beltis greatly reduced; meanwhile, the waste of a plurality of rubber in the trimming process of the of the rubber conveyor belt is avoided.

Description

technical field [0001] The invention relates to a production method of a canvas rubber conveyor belt, in particular to a production method of a canvas core conveyor belt without trimming. Background technique [0002] Conveyor belt is an important device used to transport materials in industrial production. The current rubber conveyor belt generally has a canvas core conveyor belt and a steel wire core conveyor belt. In the current canvas core conveyor belt, the rough canvas and the belt blank are bonded together, vulcanized and cooled, and then trimmed, and finally reach the specified size of the canvas core conveyor belt. Such a production method must make the canvas 30-40mm wider than the specified size, and the width of the canvas with the blank and the blank must be the same, and then trim the edge after processing, which will cause a lot of rubber waste and increase the trimming. The process increases the input of human and physical resources and increases the product...
