In the process of heating up, the plate vulcanizing machine sometimes shows that the temperature rise is slower than normal. At this time, we should think about whether a certain plate is not hot or the temperature is low; secondly, the contactor is often open during the heating process. The reason is that the temperature controller fails or some heating tubes are damaged. For this problem of the injection-compression flat vulcanizer, the solution is to replace and repair the temperature controller or the heating tube according to the degree of damage; the equipment must be stopped during the replacement process, and the power supply is blocked for repair after the temperature drops. operating. The injection press vulcanizing machine is a wire and cable testing equipment that provides the pressure and temperature functions required for vulcanization. The difference between the measuring points of the hot plate at the time of normal vulcanization is controlled by ±3°C. Considering the uniformity of heating temperature, each hot plate should be divided into multiple sections of steam in and out, and a temperature sensor should be installed on each layer of the hot plate. On the console, PLC touches the temperature display, pressure display and temperature and pressure over-limit alarm system of the display screen. Prompt the temperature error and pressure of each layer so that the operator can adopt the appropriate method. The vulcanization temperature of the injection-compression flat vulcanizer can be controlled between 145-160°C, and the pressure can be controlled between 0.8Mpa-24Mpa. The PLC and control system selected by the injection-pressing plate vulcanizer can not only store the temperature, system pressure, and time data of each point of the vulcanization process; the same screen displays the current time-temperature, time-pressure, and historical data can be checked at any time to trace quality problems. At the same time, it can also make the tread groove exhaust smoothly. The pressure during exhaust, the number of seconds during exhaust, and the number of exhaust times can be set on the screen. After exhausting, the vulcanization pressurization process can be divided into 6 levels to gradually pressurize. The user can set the pressurization value and interval time of each level, and the entire vulcanization process is automatically completed after setting.
