Rubber preformer is plunger structure machine,is mainly composed of extrusion equipment, hydraulic system, electric heating system, vacuum system, water cycle system, pneumatic system and cutting system and electric control system composition:

1. Extrusion device: consists of hydraulic cylinder, cylinder, head, etc.

2. Hydraulic system: Choose high pressure gear pump, flow valve, the hydraulic oil of hydraulic cylinder by the flow control valve controlled, the differential pressure before and after the throttle valve control always in a constant value, ensure accurate control the weight of the rubber cutting billet.

3. Pneumatic device: is used to control turn on or turn off of the nose.

4. Vacuum system: Should be vacuum before cutting rubber, rule out the air of barrel and head inside and the gas mixed in rubber, to improve the quality of the next working procedure sulfide products.

5. Heating system: Adopt the water circulation heating method, the temperature is controlled and displayed by the digital thermostat. Ensure that the temperature of the machine head and barrel is constant.

6. Cutting device: It is composed of frame, motor and deceleration system. The cutting motor adopts a frequency converter to achieve stepless speed regulation, and a transmission device is installed in the lower part of the frame.

7. Use high-definition LCD touch screen and PLC to achieve fully automatic control operation.

8. The electronic scale feedback system is used for communication control, and the knife speed is automatically adjusted to make the cut rubber blank reach the required weight.
