Product Description

Detailed explanation of PVC downspout production equipment (production process):

(1) Mixing of raw materials: adding PVC stabilizers, plasticizers, antioxidants and other auxiliary materials into the high-speed mixer according to the proportion and process. The materials are heated to the set process temperature through self-friction between the materials and the machine. The material is reduced to 40-50 degrees by the cold mixer; in this way, it can be added to the hopper of the extruder.
(2) Extruder part: This machine is equipped with a quantitative feeding device to match the extrusion volume with the feeding volume and ensure stable extrusion of the product. Due to 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 relatively large, which is conducive to the plasticization of the material. The small diameter of the screw in the metering section reduces the heat transfer area and the melt. The shear speed enables the melt to be extruded at a lower temperature. When the screw rotates in the barrel, it plasticizes the PVC mixture and pushes it to the machine head, so as to achieve compaction, melting, mixing and homogenization; and to achieve 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) Extrusion die head part: the PVC that has been compacted, melted, mixed and homogenized, and the subsequent materials are pushed to the die head by the screw. The extrusion die head is a key part of pipe forming.
(4) The vacuum shaped water tank is used for the shaping and cooling of the pipes. The vacuum shaped water tank is equipped with a vacuum system and a water circulation system for shaping and cooling. The stainless steel box body, circulating water spray cooling, and the vacuum shaped water tank are equipped with forward and backward moving devices and Manual device for adjusting left and right and height.
(5) The traction machine is used to continuously and automatically lead the cooled and hardened pipe from the machine head, with frequency conversion and speed regulation.
(6) Cutting machine: After being controlled by the travel switch according to the required length, it will automatically cut, and delay the overturning, and implement flow production. The cutting machine uses the fixed-length switch signal as a command to complete the entire cutting process. The pipe operation is kept synchronized, and the cutting process is completed by electric and pneumatic drive. The cutting machine is equipped with a dust suction device to suck out the cutting debris in time and recover it.
(7) The turning action of the turning frame is realized by the air cylinder through the air circuit control. The turning frame is equipped with a limit device. When the cutting saw cuts the pipe, the pipe continues to be transported. After a delay, the cylinder enters the work to realize the turning Material movement, to achieve the purpose of unloading. After unloading, it will automatically reset after a few seconds delay, and wait for the next cycle.
