Enengy Saving Pvc Pipe Extrusion Machine Double Screw Extruder 38CrMoAlA Screw Material

Plastic Extrusion Equipment PVC pipe extrusion

The main technical parameters:

Usage and scope of application:
Plastic pipe production line is mainly used in the production of agricultural water supply and drainage, building water supply and drainage, cable laying etc. Various kinds of PVC plastic pipe material, pipe diameter and wall thickness of the unit by the conical twin-screw extruder, vacuum calibrating bench, tractor, cutting machine, stacking frame, etc. The screw extruder and tractor adopt the imported ac frequency conversion speed regulating device, vacuum pump and the traction motor adopts high quality product. Traction have two claws, three claws, four claws, six claw drawing method, etc. Can choose blade or planetary cutting form, the other can take meter long and thickening of the device, reliable performance, high production efficiency. The company can according to customer requirements, special device production screw
Rotary muffler tube and core layer foam tube unit

This production line is mainly used to produce PVC pipes, which are widely used in building water pipes, water pipes and drainage pipes.

The production line is composed of conical twin-screw extruder, vacuum shaping table, tractor, cutting machine, material turning frame, screw extruder and tractor.

PVC pipe production line adopts imported ac frequency conversion speed regulation device, vacuum pump and traction motor are using high-quality products, traction has crawler type, two claws, three claws, four claws, six claws and other traction methods.

(1) raw materials for PVC plastic pipe extrusion line are mixed: PVC stabilizer, plasticizer, antioxidant and other auxiliary materials are added into the high-speed mixer successively according to the proportion and process. The material is heated up to the set process temperature by the friction between the material and the machine, and then the material is reduced to 40-50oc by the cold mixing machine;
In this way, it can be added to the hopper of the extruder.

(2) extruder part of PVC plastic pipe extrusion line: the machine is equipped with quantitative feeding device, so that the extruding amount and the feeding amount can match to ensure the stable extrusion of products.
Due to the characteristics of conical screw, the feeding section has a larger diameter, the heat transfer area and shear speed of the material is larger, which is conducive to the plasticization of the material, the measurement section screw diameter is small, reducing 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, push the PVC mixture to the head after plasticizing, so as to achieve compaction, melting and mixing homogenization;
And achieve the purpose of exhaust, dehydration.
Feeding device and screw drive device adopt frequency conversion speed regulation, which can realize synchronous speed regulation

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

(4) PVC plastic pipe extrusion production line, vacuum calibrating tank for a double injection mold, used for styling, cooling pipes, vacuum system for setting and cooling water tank on the vacuum system and water circulation system, stainless steel casing, circulating water spray cooling and vacuum system before and after the mobile device mounted on the tank and the left and right sides, high and low adjusting device manually.

(5) the traction machine of PVC plastic pipe extrusion line is used for continuously and automatically drawing the cooled and hardened pipe from the machine head and adjusting speed with frequency conversion.

(6) of PVC plastic pipe extrusion production line cutting machine: according to the required length by travel switch control, automatic cutting, and delay the plane, the water production, cutting machine to pronounce long switch signal instructions, complete the whole cutting process in cutting process and the pipe running in sync, cutting process completed by electric and pneumatic drive, cutting machine is equipped with suction device, sucked out cutting the debris in a timely manner, and recycling.

(7) the tilting action of the material rack in the PVC plastic pipe extrusion line is realized by the cylinder through the air path control. The tilting is set up with a limit device. After cutting and sawing off the pipe material, the pipe material continues to be transported.
After unloading, it is automatically reset after a delay of several seconds, waiting for the next cycle.
