Plasitc double cabity PVC pipe production line is mainly used for the production of various pipe diameters and wall thickness plastic PVC pipes for agricultural water supply and drainage, construction water supply and drainage, cable laying, etc.
Production process of PVC pipe production line:
The mixing of raw materials for the plastic pipe extrusion line:PVC stabilizers, plasticizers and other auxiliary materials are added to the high-speed mixer according to the proportion and process.The materials are heated to the set process temperature by the self-friction of the material and the machine.The cold mixer reduces the material to 40-50C; this can be added to the hopper of the extruder.
Extruder part of plastic pipe production line:
A1: The extruder is equipped with a quantitative feeding device, so that the extrusion volume can be matched with the feeding volume, and the product can be extruded stably. Due to the characteristics of the conical screw, the feeding section has a larger diameter, and the heat transfer area and shear speed of the material are relatively large, which is conducive to the plasticization of the material.
A2: The small screw diameter in the metering section reduces the heat transfer area and the melt. The high shear speed enables the melt to be extruded at a lower temperature.
When the screw rotates in the barrel, it plasticizes the PVC mixture and pushes it towards the machine head, so as to achieve compaction, melting, mixing and homogenization; and to achieve the purpose of exhaust and dehydration.
A3: The feeding device and screw drive device adopt frequency conversion speed regulation, which can realize synchronous speed regulation.A4:The plastic pipe production line is composed of a conical twin-screw extruder, a vacuum setting table, a tractor, a cutting machine, a stacking frame, etc. The traction has two-claw, three-claw, four-claw, and six-claw traction methods. Saw blades or planets can be selected. The cutting mode can also be equipped with length counting and thickening devices, the unit has reliable performance and high production efficiency.
According to the requirements of customers, the equipment can be configured to produce spiral silencer pipe and core foam pipe unit.
