PVC pipe production machine description
(1) raw materials mixing: pvc pipe production machine use PVC stabilizer, plasticizer, antioxidant and other auxiliary materials. In the high speed mixer, the material is heated to the setting process temperature by material and mechanical self-friction, and then the material is reduced to a cold mixer. 40-50 degrees; This can be added to the hopper of the extruder.
(2) PVC pipe production machine extruder part: the machine is equipped with a quantitative feeding device, so that the extrusion amount can be matched with the feeding amount to ensure the stable extrusion of products. Due to the characteristics of conical screw, the feeding section has a larger diameter, and the heat transfer area and shear speed of the material are relatively large. It is conducive to the plasticization of the material, the diameter of the measuring segment screw is small, reducing the heat transfer area and the shear rate of the melt, so that the melt can be extruded at a lower temperature. When the screw is rotated inside the cylinder, the PVC is plasticized and pushed to the head to achieve compaction, melting and mixing. And realize the purpose of exhaust and dehydration. The feeding device and the screw drive device adopt the frequency conversion speed regulation, can realize synchronous speed adjustment.
(3) PVC pipe production machine extrusion die head: after compaction, melting and mixing of PVC, there is a follow-up material which is pushed to the die head by the screw rod, and the extrusion die is the closed part of pipe forming.
(4) PVC pipe production machine vacuum system 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) PVC pipe production machine tractor is used to continuously and automatically draw the cooled and hardened tube from the nose, and the frequency control.
(6) PVC pipe production machine cutting machine: automatic cutting is performed after the travel switch is controlled according to the required length.
Cutting machine to pronounce long switch signal instructions, complete the whole cutting process in cutting process and 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) PVC pipe production machine the tumbling action is realized by the air cylinder through the air path control, and a limit device is installed on the rolling stock, when the cutting saw cuts the pipe. After the pipe continues to transport, after the delay, the cylinder enters the work, realizes the turning movement, achieves discharging purpose. After discharge the seconds automatically reset and wait for the next cycle.
