Soft Pvc Pellet Extruder Machine Twin Screw Air Cooling Hot Cutting Granulator

Soft PVC granulation pelletizing machine air cooling hot cutting granulator

PVC can be divided into soft PVC and hard PVC. Hard PVC accounts for about 2/3 of the market and soft PVC accounts for 1/3. Soft PVC is generally used in the surface of floors, ceilings and leather, but because soft PVC contains softeners (this is also), it is easy to become brittle and not easy to preserve, so the scope of its use is limited. Hard PVC does not contain softeners, so it is flexible, easy to form, not brittle, and has long storage time. Therefore, it has great application value. The essence of PVC is a vacuum plastic film, which is used for the surface packing of various panels. So it is also called decorative film and adhesive film. It is used in many industries, such as building materials, packaging, medicine and so on. Among them, the proportion of building materials industry accounts for sixty percent, followed by. the packaging industry, as well as a number of other small sectors.

In general, a parallel twin screw granulator is used in the soft PVC. The overall output and quality are still granulated by twin screw granulator, and the product is more homogeneous and energy consumption is also smaller.

Precautions of PVC granulation machine

1. The main motor and the oil pump motor are electrically interlocked, that is, the motor of the oil pump does not start, the main motor can not start; the main motor does not stop, and the oil pump motor can not stop.

2, the main motor and feed motor have electrical chain, that is, the main motor does not start, feed motor can not start; feed motor main motor does not stop, the main motor can not stop.

3. The main motor control cabinet has over current protection. In addition, it also has a mechanical protection device, usually a nylon shear pin type coupling. When the torque is exceeded, the shear pin is cut off and the gearbox stops working.

4. When the head pressure exceeds the set alarm value, the material pressure alarm signal lights up and automatically stops.

5. Raw materials produced by users are strictly forbidden to bring in any metal objects.

6. When the machine is running, it is forbidden to use metal objects to clean the material at the opening of the cylinder.

7, pressure sensor and material thermocouple assembly and disassembly. When the material is in the head, the material can be installed and disassembled until the material is softened. Please use softened water or distilled water for circulating water of cylinder

8 and cooling system.

9, the screw can only start at low speed (less than 20r/min), and the idle time does not exceed 2 minutes. After feeding, the speed of the die can be increased gradually until the die hole is discharged.
