The method of using the vulcanizing machine
the flat vulcanizing machine is mainly used for vulcanizing flat belts (such as conveyor belts, transmission belts, flat belts for short), and belongs to hydraulic machinery. The main function of the flat vulcanizing machine 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, heat transfer oil, etc., superheated water is also useful). Conveyor belt plate vulcanizing machine is mainly used for vulcanizing flat tape, rubber sheet, polymer and other flat products. It has the advantages of high pressure per unit area of hot plate, reliable operation and less maintenance. The temperature is provided by a heating medium (usually steam, heat transfer oil, etc.). According to the structure of the frame, the flat-belt vulcanizing machine can be divided into two types: column-type flat-belt vulcanizing machine and frame-type flat-belt vulcanizing machine; according to the number of working layers, it can be divided into single-layer and multi-layer: according to the hydraulic system The working medium can be divided into oil pressure and water pressure.

Operation steps of flat vulcanizing machine
1. Preparation
(1) Check the amount of hydraulic oil before use. The height of the hydraulic oil is 2/3 of the height of the lower machine base. When the amount of oil is insufficient, it should be added in time. The oil must be finely filtered before injection. Add pure 20# hydraulic oil into the oil injection hole of the lower machine base. The oil level can be seen through the oil gauge, and it is generally added to the height of 2/3 of the lower machine base.
(2) Check the lubrication between the column shaft and the guide frame and add oil in time to maintain a good lubrication operation.
(3) Turn on the power, move the operating handle to the vertical position, close the oil return port, press the motor start button, the oil from the oil pump enters the oil cylinder, and drives the plunger to rise. When the hot plate is closed, the oil pump continues to supply oil , When the oil pressure rises to the rated value (14.5MPa), press the registration stop button, so that the machine is in the state of stopping and maintaining pressure (that is, timing vulcanization), and when the vulcanization time is reached, move the handle to lower the plunger to open the mold.
(4) Temperature control of the hot plate: Turn on the rotary button SA1, the plate will start heating, and when the temperature of the plate reaches the preset value, the heating will stop automatically. When the temperature is lower than the set value, the plate is automatically heated to keep the temperature at the set value.
(5) Control of vulcanizing machine action: Press the motor start button SB2, the AC contactor is powered on, and the oil pump works. When the hydraulic pressure reaches the set value, the AC contactor is disconnected, and the vulcanization time will be automatically recorded. When the pressure drops, the oil pump motor starts. Automatic pressure supplement, when the set vulcanization time is reached, the buzzer will sound to inform that the vulcanization time has come, and the mold can be opened, press the sound stop button, move the manual operation valve, and make the plate drop, and the next cycle can be carried out.
