What are the components of pvc pipe extrusion line?

Extruder part of the pvc pipe extrusion line: This extrusion machinery is equipped with a quantitative feeding device to match the extrusion amount with the feeding amount, ensuring stable extrusion of the product. Due to the use of conical twin screws and the larger diameter of the feeding section, the heat transfer area and shear rate of the material are relatively large, which is conducive to the plasticization of the material. The smaller diameter of the measuring section screw reduces the heat transfer area and shear rate of the melt, allowing the melt to be extruded at lower temperatures. When the screw rotates inside the barrel, it plasticizes the PVC mixture and pushes it towards the machine head, achieving compaction, melting, and mixing homogenization; And achieve the purpose of exhaust and dehydration. The feeding device and screw drive device adopt frequency conversion speed regulation, which can achieve synchronous speed regulation.

Die head part: PVC that has been compacted, melted, and homogenized through mixing, with subsequent materials pushed towards the die head through screws. The extrusion die head is a crucial component for pipe forming.

Vacuum sizing water tank part: Adopting our company’s independently developed cooling and sizing system, a specially designed stainless steel box with an extended vacuum sizing box, coupled with circulating water spray cooling, can ensure stable diameter size and roundness. The use of speed control system ensures stable traction speed. And the vacuum sizing water tank is equipped with a forward and backward movement device and a manual device for adjusting left and right, height and height

The traction machine part of the pvc pipe machine adopts frequency conversion speed regulation, which is used to continuously and automatically guide the cooled and hardened pipes out of the machine head, saving energy and ensuring stability and durability.

Cutting machine part: After being controlled by a travel switch according to the required length, automatic cutting is carried out, and the frame is flipped with a delay to implement flow production. The cutting machine completes the entire cutting process with the fixed length switch signal as the command, and is synchronized with the pipe operation during the cutting process. The cutting process is completed by electric and pneumatic drives. The cutting machine is equipped with a vacuum device to timely suck out and recover the debris generated by cutting.

The turnover rack part of the pipe production line: The turnover action is controlled by the air cylinder through the air circuit. The turnover installation is equipped with a limit device. When the cutting saw cuts the pipe, the pipe continues to be transported. After a delay, the cylinder enters work to achieve the turnover action and achieve the unloading purpose. After unloading, it will automatically reset after a delay of several seconds, waiting for the next cycle.
