PVC pipe production line equipment function

(1), the mixing of raw materials: PVC stabilizers, plasticizers, antioxidants and other accessories, in proportion, the craft has joined the high speed mixer, the materials and machinery from the friction material temperature to set the process temperature, and then materials down to 40-50 degrees by cold mixing machine; so that you can be added to the extruder hopper.
(2), extruder parts: the machine is equipped with a dosing device so that the extrusion amount of the feedstock to be able to match to ensure stable extrusion of products. Due to the characteristics of the tapered screw feed zone has a larger diameter, the heat transfer area of ​​the material and the shear rate is relatively large, materials plasticizing small screw diameter of the metering section, reduce the heat transfer area and the shear velocity of the melt, the melt extrusion at a lower temperature. Screw rotating in a drum machine, PVC compound material plasticizing push the nose, so as to achieve compaction, melting, mixing, homogenization; and to achieve exhaust the purpose of dehydration. Feeding device and screw drive with frequency control, the synchronous speed
(3), the extrusion die part: After compaction, melting, mixing, homogenizing PVC, follow-up material by the screw to a die head, extrusion die pipe forming relationships built parts.
(4), vacuum forming tank for pvc pipe machine stereotyped for stereotyping and cooling of the vacuum system and water circulation system is equipped with a cooling, vacuum calibrating water tank, stainless steel box, recycled water spray cooling, vacuum calibrating water tank is equipped with a mobile device before and after left and right, high and low adjust the device manually.
(5), the tractor is used for continuous, automatic pipe cools and hardens the lead from the nose at the Frequency Control.
(6), cutting machines: according to the requirements of the length of the control by the travel switch, automatic cutting, and turning frame delay, the implementation of water production, cutting machine for the instruction to set the long-term employment switching signal, complete the cutting of the whole process in the cutting process pipe running to keep pace, the cutting process is completed by the electric and pneumatic drive, cutting machine has a vacuum device, cutting debris promptly sucked out and recover.
(7), tilter, stirring action by the cylinder pneumatic control to achieve stirring erection of a limit device after cutting saw to cut pipe, pipe continued transmission, by the delay, the cylinder into the work, to achieve turn material movement, to reach the discharge purpose. Delay a few seconds automatically reset after the discharge, wait for the next cycle.
