The rubber preforming machine is a high-precision and high-efficiency rubber blank making equipment. It can produce various medium and high hardness rubber blanks in various shapes, and the rubber blank has high precision and no bubbles. It is suitable for the production of rubber miscellaneous parts and oil seals. , O-rings, tennis, golf balls, valves, soles, auto parts, medicine, agricultural granulation and other products.
Rubber preforming is a plunger-type machine, which is mainly composed of extrusion device, hydraulic system, vacuum system, water circulation system, electric heating system, pneumatic system, cutting system and electric control system:
1. Extrusion device: It consists of hydraulic cylinder, barrel, machine head, etc.
2. Hydraulic device: high-pressure gear pump and flow valve are selected. The hydraulic oil of the hydraulic cylinder is controlled by the flow valve. The differential pressure valve before and after throttling is always controlled at a constant value to ensure accurate control of the weight of the extruded rubber blank.
3. Pneumatic device: used to control the opening and closing of the machine head.
4. Vacuum system: vacuumize before extruding and cutting the rubber material to remove the air inside the barrel and the machine head and the gas mixed in the rubber material, thereby improving the quality of the vulcanized products in the next process.
5. Heating system: the water circulation heating method is adopted, and the temperature is controlled and displayed by a 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 variable frequency speed regulator to achieve stepless speed regulation, and a transmission device is installed at the lower part of the frame.
7. Adopt high-definition LCD touch screen and PLC to achieve automatic control operation.
8. Adopt electronic weighing feedback system communication control to automatically adjust the knife speed to make the cut rubber blank reach the required weight.
