Jiangsu Polar Bear Machinery Co., Ltd.

1. The difference of normal vulcanization time of hot plate between each measuring point is controlled by (+3) C.

2. Considering the uniformity of heating temperature, each hot plate should be divided into several sections of steam (7.7m divided into three sections), and temperature sensors should be installed on each hot plate.

3. Temperature display, pressure display and alarm system of temperature and pressure exceeding limit of PLC touch screen on console. The temperature deviation and pressure of each layer are prompted for operators to take appropriate measures.

4. The vulcanization temperature of the equipment can be controlled between 145-160 degrees C and the pressure can be controlled between 0.8Mpa and 24Mpa.

5. PLC and control system have the following functions:

(1) Storage temperature, system pressure and time data of vulcanization process.

(2) Display current time-temperature, time-pressure on the same screen, and query historical data at any time in order to trace quality problems.

(3) Flower groove on tread exhaust smoothly. Pressure, seconds and times of exhaust can be set on the screen.

(4) After exhausting gas, the vulcanization pressure process can be divided into six stages and gradually pressurized. Users can set the pressure value and interval time of each stage. After setting, the whole vulcanization process can be completed automatically.
