What Are the Functions of the PVC Pipe Production Line Equipment?

1. The raw material mixing of the PVC extruder machine

Add PVC stabilizers, plasticizers, antioxidants, and other auxiliary materials to the high-speed mixer according to the ratio for processing. The materials are heated to the set process temperature through the natural friction between the materials and the machine, and then the materials are heated to the specified temperature. In addition, reduce S to 40-50℃ through a cold mixer. In this way, it can be added to the hopper of the PVC extruder machine.

2. The part of the PVC extruder machine

The PVC extruder machine is equipped with a quantitative feeding device to match the extrusion volume with the feeding volume, ensuring the stable extrusion of the product. Due to the characteristics of the conical screw, the diameter of the feed section is larger, and the heat transfer area and the shear speed of the material are larger, which is beneficial to the plasticization of the material.

The small diameter of the screw in the metering section reduces 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 machine head to realize compaction, melting, mixing and homogenization, and achieve the purpose of exhausting and dehydration. The feeding device and screw driving gear of the PVC extruder machine adopt frequency conversion speed regulation, which can realize synchronous speed regulation.

3. The extrusion die part of the PVC pipe production line

The PVC is pressed, melted, and stirred uniformly, and the subsequent materials are pushed onto the mold with a screw. The extrusion mold is a key part of pipe forming.

4. The vacuum forming water tank of the PVC pipe production line is used for forming and cooling pipes

The vacuum forming water tank is equipped with a vacuum system, a cooling circulating water system, a stainless steel tank body and a circulating water spray for cooling. That tank is equipped with a forward and backward movement device and a left and right height adjustment manual device.

5. The cutting machine of the PVC pipe production line 

After the stroke switch is controlled according to the required length, automatic cutting is carried out, and the frame is turned over in time to realize flow production. The cutting machine of the PVC pipe production line uses fixed-length switch signals as instructions to complete the entire cutting process, keeping it 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 dust suction device to suck out and recover the cutting debris in time.
