Along with the rapid development of modern industry, especially the chemical industry, rubber timing belt variety, but its production process, For products made from solid rubber (raw rubber),yonghangbelt factory the production process mainly includes.
Raw material preparation → plasticizing → mixing → molding → vulcanization → resting → inspection
(iii)yonghangbelt Production process
1、Preparation of semi-finished products
(1) According to the process procedures, ingredients, mixing and calendering of various rubber materials according to the required specifications.
(2) The calendered film must be of uniform thickness and free of air bubbles.
(3) After the nylon wrapping cloth has been dipped and dried, it is cut and sewn into a tube as required.
(4) Spraying special release agent on the mould to be used.
(5) Prefabricated vulcanising sleeve. Wrap several layers of film of the required thickness around the mould of the vulcanising rubber sleeve sprayed with release agent, wrap the water covered cloth and place it in the vulcanising tank, after vulcanisation, take off the mould for use.
2、Forming The prepared nylon cloth tube set on the corresponding mold together with lifting to the molding machine, according to the specified line distance and tension winding glass fiber rope, and then in the cord outside a layer of a certain thickness of tape body rubber film.
3、Vulcanisation The unvulcanised strip cylinder is lifted into the vulcanisation tank and covered with the tank lid. To the outer steam chamber into about 1.0Mpa of saturated steam, pressure after a period of time, the saturated steam into the inner steam chamber to accelerate vulcanization.
4、Cooling After vulcanization, the tube will be lifted into the cooling pool for cooling.
5、Demoulding Lift the cooled strip barrel onto the demoulding machine, select the appropriate demoulding machine, clamp the mould, start the lower ejector pin to eject the mould from the strip barrel and put the mould into the mould storage area for use.
6、Grinding The stripped strip barrel is set into the grinding machine and ground to the required size and removed.
7、Label printing
8、Cutting Select a suitable cutting machine, grind the surface of the cutting bushing smoothly and put it on the expansion drum or cutting roller, put the strip barrel on and tension it, set the cutting parameters and cut automatically.
