Detailed explanation of PVC downpipe production equipment (production process)
(1) Raw material mixing: PVC stabilizer, plasticizer, antioxidant and other auxiliary materials are added into the high-speed mixer according to proportion and process. The materials are heated to the set process temperature by self friction between materials and machinery, and then the materials are reduced to 40-50 ºC by cold mixer. In this way, they can be added into the hopper of extruder.
(2) Extruder part: This machine is equipped with a quantitative feeding device, so that the extrusion amount and feeding amount can match to ensure the stable extrusion of products. Because of the characteristics of the conical screw, the feeding section has a larger diameter, and the heat transfer area and shear speed of the material are larger, which is conducive to the plasticization of the material. The diameter of the screw in the metering section is smaller, which reduces the heat transfer area and shear speed of the melt, so that the melt can be extruded at a lower temperature. When the screw rotates in the barrel, the PVC mixture is plasticized and pushed to the head, so as to achieve compaction, melting, mixing homogenization, and realize the purpose of exhaust and dehydration. The feeding device and screw drive device adopt frequency conversion speed regulation, which can realize synchronous speed regulation.
(3) PVC, PVC pipes are molded by screw, extrusion head and extrusion head.
(4) The vacuum setting water tank is used for pipe shaping and cooling. The vacuum setting water tank is equipped with vacuum system and water circulation system for shaping and cooling. The stainless steel box is equipped with circulating water spray cooling. The vacuum setting water tank is equipped with front and back moving device and left and right, high and low adjustment manual device.
(5) The tractor is used to continuously and automatically lead the cooled and hardened pipes out of the machine head, with frequency control.
