pvc pipe production line

Pipe diameter range: Φ 16- Φ 800
1. Mixed raw materials: PVC stabilizers, plasticizers, antioxidants and other auxiliary materials are added to the high-speed mixer according to the process ratio, and heated by friction with the machine to the set process temperature. Reduce the material to 40-50 degrees through a cold mixer. Then it can be added to the hopper of the extruder.
2. Extruder section: This machine is equipped with a quantitative feeding device to ensure stable extrusion. Due to the characteristics of conical twin-screw, the feeding section has a larger diameter, which is beneficial for the plasticization of materials. When the screw rotates inside the barrel, the PVC mixture is plasticized and pushed towards the machine head, achieving homogenization through compaction, melting, and mixing; To achieve the purpose of exhaust dehydration. The feeding device and screw drive device adopt variable frequency speed regulation, which can achieve synchronous speed regulation.
3. Extrusion die part: After PVC is compacted, melted, mixed, and homogenized, the subsequent material is pushed to the die by a screw. The extrusion die is a composite component for forming pipes.
4. Vacuum shaping tank: used for shaping and cooling pipelines with vacuum and water circulation systems installed. And equipped with front and rear movement devices and left and right height manual adjustment devices.
5. Traction machine (variable frequency speed regulation): used for continuously and automatically pulling the hardened tube out of the machine head.
6. Cutting machine: After controlling the distance switch according to the required length, it performs automatic cutting.
7. Stacker crane: The flipping of the stacker crane is controlled by pneumatic cylinders.
