Plastic pipe production line equipment has a control system, and then through the extruder, machine head, stereotypes cooling system, traction machine, cutting equipment and turning rack composition. The extrusion principle of extrusion machine is the use of screw thread with inclined rotating in the cylinder heating in the hopper brought forward plastic extrusion, plastic gradually heating, uniform plasticizing plastic extrusion molding, and through the nose. In the actual operation of the extruder, pay attention to a few points:

1 before starting, check whether the heating ring is good, whether the thermocouple is inserted and the temperature is accurate

2. start when the heating temperature to set the process temperature, and heat insulation for a certain period of time before starting. To prevent the motor, screw and other parts damaged.

3. host must first start running at low speed for several minutes, will melt the barrel last remaining drained, to melt pressure and current stability after the host material spraying speed, so as to avoid hurting people.

4. equipment operation should observe the temperature, current, melt pressure and other parameters at any time. And observe the heating situation of the motor and reducer, and find out the cause in time and eliminate it when there is abnormal

5. heating time, depending on the size of the nose, 63 machine head is not less than 3 hours, 250 head is not less than 6 hours, 450 head is not less than 8 hours

6., the choice of mold: according to product specifications to choose the appropriate mold, if the mold selection is inappropriate, it will bring difficulties to production

7. plastic pipe production line mold protection: the quality of the mold determines the quality of the product, the mold material is generally die steel, surface chrome treatment, hardness difference. Therefore, in the disassembly and handling process must be protected, there is no scratches and collisions. The general mold can not be placed directly on the ground, should be put on rubber or woodwind is appropriate. Do not strike with a solid sharp tool when replacing the mold.

8. core concentricity adjustment: core mould production line of solid wall pipe for the regulation of the follow the "loose thin Dinghou" principle. It is to loosen the screw in the small direction and tighten the screw in the big gap direction.

9. heating ring protection: in general, the heating coil life is very long, often in the process of disassembly damage, therefore, the heating ring in the demolition process should be extra careful.
