Constant pressure steam pressing plate vulcanizing device

Technical Field

The utility model relates to a vulcanizing press especially relates to a constant voltage steam clamp plate vulcanizer.

Background

The flat vulcanizing machine is mainly used for vulcanizing asbestos-free sealing plates, belongs to hydraulic machinery, and mainly has the function of providing pressure and temperature required by vulcanization. Pressure is generated by the hydraulic system through hydraulic cylinders and temperature is provided by a heating medium (typically steam, heat transfer oil, etc., superheated water is also useful). The flat belt vulcanizing press can be mainly divided into a column type flat belt vulcanizing press and a frame type flat belt vulcanizing press according to the structural form of a frame; the number of working layers can be divided into single-layer and multi-layer: the working medium of the hydraulic system can be divided into oil pressure and water pressure.

The main working process is as follows: after the unvulcanized semi-finished product was loaded into the mold, the mold was placed in the gap between two hot plates (for non-molded articles such as tapes, slabs, directly between the hot plates). Then, hydraulic medium (oil or water) is fed into the hydraulic cylinder, and the plunger pushes the movable platform and the hot plate to move upwards or downwards and pushes the movable platform to press the mould or the product. After a period of time (vulcanization period) and the vulcanization of the product are completed, the hydraulic medium in the hydraulic cylinder is removed, and the product can be taken out because the plunger descends under the action of self weight (or hydraulic pressure of the double-acting cylinder).

In the prior art, hydraulic pressure is generally used for providing pressure, and a heating medium is used for providing vulcanization temperature. The energy consumption is large, and the sustainable development requirement of energy conservation and environmental protection is violated. And the existing plate vulcanizing machine does not use a feeding device, raw materials can only be manually put in by an operator, so that the working content of the operator is increased, the processing temperature of the raw materials is high, workers are easily scalded, and potential safety hazards exist.
