(1) Raw material mixing: PVC stabilizer, plasticizer, antioxidant and other auxiliary materials are added into the high-speed mixer successively according to the proportion and process, and the material is heated to the set process temperature through the material and mechanical self-friction, and then the material is reduced to 40-50 degrees by cold mixing machine; This allows it to be added to the hopper of the extruder.

(2) Extruder part: The machine is equipped with quantitative feeding device, so that the amount of extrusion and feeding can match, to ensure the stable extrusion of products. Due to the characteristics of the conical screw, the feeding section has a large diameter, the heat transfer area and shear speed of the material is relatively large, conducive to the plasticization of the material, the metering section screw diameter is small, reduce the heat transfer area and the shear speed of the melt, so that the melt can be extruded at a lower temperature. When the screw rotates in the barrel, the PVC mixture is plasticized and pushed to the head, so as to achieve compaction, melting, mixing and homogenization; And achieve the purpose of exhaust and dehydration. The feeding device and screw drive device adopt frequency conversion speed regulation, which can realize synchronous speed regulation.

(3) Extrusion die head part: after compaction, melting, mixing and homogenization of PVC, there are subsequent materials pushed to the die head by screw, extrusion die head is a key part of pipe forming.

(4) Vacuum setting water tank is used for tube setting and cooling, vacuum setting water tank is equipped with vacuum system and water circulation system for setting and cooling, stainless steel box, circulating water spray cooling, vacuum setting water tank is equipped with front and back moving device and left and right, high and low adjustment manual device.

(5) The tractor is used for continuously and automatically drawing out the cooled and hardened pipe from the head, frequency conversion and speed regulation.

(6) Cutting machine: By the travel switch according to the required length control, automatic cutting, and delay over, the implementation of flow production, cutting machine to fixed length switch signal as the instruction, complete the whole cutting process, in the cutting process and pipe operation keep synchronized, cutting process by electric and pneumatic drive to complete, the cutting machine is equipped with a dust suction device, the cutting generated debris in time out, and recovery.

(7) The turning movement of the turning frame is realized by the cylinder through the air path control, and the turning movement is set up with a limiting device. When the cutting saw cuts off the pipe, the pipe continues to transport. After a delay, the cylinder enters the work to realize the turning movement and the purpose of unloading. After unloading, it will automatically reset after a delay of several seconds and wait for the next cycle.
