Plastic Profile Extrusion Line Plastic Profile Extrusion Line Equipment Function Plastic Profile Extrusion Production Line Unique structure, high degree of automation, easy operation, continuous production is stable and reliable. The pipe produced by the plastic pipe production line has a moderate rigidity, strength, but also has good flexibility, creep resistance, resistance to environmental stress cracking and good thermal fusion performance, has become the city gas pipeline and outdoor water supply preferred products The

  (1) raw material mixing: PVC stabilizer, plasticizer, antioxidants and other accessories, in proportion, the process has joined the high-speed mixer, the material and mechanical friction from the material to set the temperature to set the process temperature, and then The cold mix reduces the material to 40-50 degrees; this can be added to the hopper of the extruder.

  (2) extruder part: the machine is equipped with a quantitative feeding device, so that the amount of extrusion and feeding can match to ensure that products stable extrusion. Due to the characteristics of the conical screw, the feeding section has a large diameter, the material heat transfer area and shear rate is relatively large, is conducive to the plastic material, measuring the screw diameter is small, reducing the heat transfer area and the melt Of the shear rate, so that the melt can be squeezed at a lower temperature. Screw in the barrel when the rotation, the PVC mixture plasticized to the nose, so as to achieve compaction, melting, mixing homogenization; and to achieve the purpose of exhaust, dehydration. Feeding device and screw drive device using frequency control, can achieve synchronous speed

  (3) extrusion die part: by compaction, melting, mixing homogenized PVC, a follow-up material by the screw to the die, extrusion die is the pipe forming the building components.

  (4) Vacuum Forming Water Tank For the setting, cooling and vacuum setting of the pipe, the vacuum system and the water circulation system for the type and cooling are installed, the stainless steel box, the circulating water spray cooling, the vacuum setting tank is equipped with front and rear mobile devices and Left and right, high and low adjustment manual device.

  (5) traction machine for continuous, automatic cooling has been hardened pipe from the nose at the lead, frequency control.

  (6) cutting machine: the length of the switch according to the required length of control, the automatic cutting, and delay the flip, the implementation of water production, cutting machine to set the switch signal as a directive to complete the cutting process, in the cutting process and pipe Running to keep the synchronization, the cutting process by the electric and pneumatic drive to complete, cutting machine with a vacuum device, the cutting debris generated in time to suck out and recovery.

  (7) Plastic Profile Extrusion Line turn the material frame rolling action by the cylinder through the gas control to achieve, turn the rack with a limit device, when the cutting saw cut pipe, the pipe continues to transport, after the delay, the cylinder into the work, Action, to discharge purposes. Discontinued after a few seconds automatically reset, waiting for the next cycle.
