The characteristics of PVC pipe extrusion production line and the formation of extrusion touch

Ⅰ. Characteristics of pipes produced by PVC pipe extrusion line

1. The construction is simple, the joint between the PVC pipes produced by the PVC pipe extrusion line is very easy, which can speed up the construction speed and greatly reduce the construction cost.

2. Light weight, convenient handling and loading and unloading, the material of PVC pipe is very light, which has huge advantages in handling and loading and unloading, which reduces a lot of trouble for construction, thus saving labor and improving efficiency.

3. It does not affect the water quality. The pipes produced by the PVC pipe extrusion line have been confirmed in the dissolution test that their use does not affect the water quality, and the PVC pipe has now become a tap water pipe.

4. Excellent chemical resistance, PVC pipe has excellent acid resistance, alkali resistance and corrosion resistance, and is widely used in the chemical industry.

5. Good electrical insulation, PVC pipe has excellent electrical insulation, suitable for wire, cable conduit, and wire piping on buildings is the best choice.

6. High mechanical strength, PVC pipe has good performance in water pressure resistance, external pressure resistance and impact resistance, and is suitable for piping projects under various conditions.

7. The fluid resistance is small. The wall surface of the PVC pipe produced by the PVC pipe extrusion line is smooth, and the resistance to the fluid is small. The roughness coefficient is only 0.009. Compared with other pipes, the resistance generated by the PVC pipe is small.

Ⅱ. How is the extrusion head of the PVC pipe extrusion line formed?

After compacted, melted, mixed and homogenized PVC, the follow-up material is pushed to the die head by the screw, and the extrusion die head is the key part of pipe forming.

The vacuum setting water tank is used for the shaping and cooling of pipes. The vacuum setting water tank is equipped with a vacuum system and a water circulation system for setting and cooling, a stainless steel box, and circulating water spray cooling. Manual device.

The tractor is used to continuously and automatically lead the cooled and hardened pipes out of the head of the PVC pipe extrusion line, and the speed is controlled by frequency conversion.

Cutting machine: After being controlled by the travel switch according to the required length, automatic cutting is performed, and the frame is turned over with a delay to implement flow production. The cutting machine takes the switch signal as the command to complete the entire cutting process.

During the cutting process, it is synchronized with the operation of the pipe extrusion line. The cutting process is completed by electric and pneumatic drives. The cutting machine is equipped with a vacuum device to suck out the debris generated by cutting in time and recover it.

The turning action of the turning frame is realized by the air cylinder through the control of the air circuit. The turning frame is equipped with a limit device. After the cutting saw cuts the pipe, the pipe continues to be conveyed. After a delay, the cylinder of the extrusion line starts to work to realize the turning. action to achieve the purpose of unloading. After unloading, it will automatically reset after a delay of several seconds, waiting for the next cycle.
