Rubber flat vulcanizing machine manufacturers: automatic flat vulcanizing machine is mainly used for flat belt (such as conveyor belt and transmission belt, referred to as flat belt) vulcanization. It has the advantages of high pressure per unit area of hot plate, reliable operation of equipment and less maintenance. The main function of the plate vulcanizer is to provide the pressure and temperature required for vulcanization. The pressure is generated by the hydraulic system through the hydraulic cylinder, and the temperature is provided by the heating medium (usually steam). Rubber itself has the characteristics of elasticity, wear resistance and good air tightness. It is because of its elasticity that rubber processing is difficult, especially to obtain products with a certain shape. Therefore, it is necessary to use glue mixing equipment to mix glue, increase plasticity, reduce elasticity, and then process semi-finished products, and then restore the plastic semi-finished products to their original elasticity. This process is called vulcanization.

Rubber vulcanizing machine manufacturer: vulcanizing machine usually consists of four parts: clamping mechanism, two control system and the third pressure system. The clamping mechanism of the four heating elements usually consists of a frame and bolts. The control system consists of an electric control box and a secondary line, the pressure system consists of a hydraulic pressure plate and a pressure test pump, and the heating system consists of a heating plate and an insulating plate.

Rubber flat vulcanizing machine manufacturers: characteristics of automatic flat vulcanizing machine

(1) Under a certain base distance, it is allowed to install hydraulic cylinders with a larger diameter, which can reduce the number of hydraulic cylinders, the structure is simple, and the amount of maintenance is small;

The upper beam is stressed reasonably, and the required section modulus is much smaller than that of the column beam, which can reduce the weight;

The manufacturing equipment is simple, the pipeline configuration is hidden, and the appearance of the whole machine is neat and beautiful.

Rubber flat vulcanizer manufacturer: When the vulcanizer is working, the hot plate heats the rubber compound to crosslink the rubber molecules, and its structure changes from a linear structure to a mesh structure, and products with certain physical and mechanical properties can be obtained. However, after the rubber mixture is heated, it begins to soften, and at the same time, the water and volatile substances in the rubber mixture vaporize. At this time, the hydraulic cylinder is used to give sufficient pressure to fill the model with rubber, limit the generation of bubbles, and make the product structure dense. If it is a tape layer product, the adhesive can be firmly adhered to the cloth. In addition, sufficient pressure should be given to prevent the mold parting surface from overflowing, pattern lack of glue, pore sponge and other phenomena.

Rubber flat vulcanizer manufacturer: After putting the unvulcanized semi-finished product into the mold, put the mold into the gap between the two hot plates. Then, the hydraulic medium is introduced into the hydraulic cylinder, and the plunger pushes the movable platform and the hot plate to move up and down, pushing the movable plate to compress the mold or product. When the above movement is performed, the heating medium is introduced into the heating plate, so that the mold (or product) can obtain the pressure and temperature required for the vulcanization process. After a period of time (vulcanization cycle), the product is vulcanized. At this time, the hydraulic medium in the hydraulic cylinder is removed, and the product can be taken out because the plunger drops under its own weight.
