Description

Top-mounted flat vulcanizer

technical field

The invention relates to the technical field of flat vulcanizers, in particular to an upper-mounted flat vulcanizer.

Background technique

Flat belt vulcanizing machine is mainly used for vulcanizing flat belts such as conveyor belts, transmission belts, etc. It has the advantages of high pressure per unit area of hot plate, reliable equipment operation and less maintenance. Its structure mainly includes a frame and a vulcanization device for vulcanizing the flat tape. The main function of the pressing mechanism is to provide the pressure required for vulcanization to the adhesive tape clamped between the upper and lower hot plates. The pressure is generally generated by a pressurized oil cylinder controlled by a hydraulic control system. At present, the commonly used flat vulcanizers mostly use a bottom-mounted pressurizing mechanism in which the pressurized oil cylinder is placed under the lower hot plate to press the lower hot plate. In order to stabilize the vulcanization pressure of the flat vulcanizer under the oil cylinder, the upper and lower hot plates need to be connected with heavy beam frames. Maintenance is inconvenient, and the cost of use is high. Since the pressurized oil cylinder is located on the frame base, close to the heat source of the vulcanizer, and the surrounding temperature is high, the service life of the oil cylinder seal will be shortened, thereby affecting the overall service life of the equipment.

In order to reduce the height of the equipment, ensure stable pressure, and at the same time reduce the influence of the heat source of the vulcanizer on the life of the pressurized cylinder, Chinese patent CN200820155540 discloses a single-layer flat vulcanization press, the lower hot plate of which is fixed on the frame by a tensioning device There is a pressurized oil cylinder between the upper hot plate and the rack plate. The structure of the pressurized oil cylinder is placed on the top of the plate. The pressurized oil cylinder is hung upside down in the The cylinder core (piston end) of the other end of a pressurized oil cylinder is connected to the upper hot plate by means of a disc spring washer and a screw through an oil collecting device. However, because the pressurized oil cylinder of the above-mentioned vulcanizer adopts the method of hanging upside down, the hydraulic oil in the oil cylinder is easy to drip and contaminate the hot plate or tape, which affects the use of the equipment. Even if an oil collecting device is installed, it is difficult to completely avoid too much hydraulic oil or heat During the movement of the flat plate, the hydraulic oil overflows the oil collecting device and contaminates the upper hot plate or the tape. Therefore, the existing pressurized oil cylinder top-mounted flat vulcanizer has a large amount of pressurized oil cylinder hydraulic oil to contaminate the equipment and tape, which affects the normal use of the equipment. And the yield of the tape is not conducive to the application of the equipment.
