Product introduction
I. Process flow of one-out-of-two PVC drainage pipe production line
    Formula → high speed mixing → low speed cold mixing → conical twin-screw extrusion → vacuum sizing, spray cooling → traction → trademark printing → fixed length cutting → flaring or not flaring → inspection → packaging and storage
Second, the function of PVC equipment
(1) PVC pipe production line raw material mixing: PVC stabilizers, plasticizers, antioxidants and other auxiliary materials, according to the proportion, process successively added to the high-speed mixer, the material and mechanical friction to make the material warmed up to the set process temperature, and then by the cold mixing machine will be lowered to the material to 40-50ºC; so that can be added to the hopper of the extruder.
(2) Extruder part of PVC pipe production line: This machine is equipped with a quantitative feeding device, so that the extruding volume and feeding volume can be matched to ensure stable extrusion of products. Due to the characteristics of conical screw, the charging section has a larger diameter, the heat transfer area and shear speed of the material is relatively large, which is conducive to the plasticization of the material, and the diameter of the screw in the metering section is small, which reduces the heat transfer area and the 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 and homogenization; and to achieve the purpose of exhausting and dewatering. The feeding device and screw driving device adopts frequency conversion speed regulation, which can realize synchronous speed regulation.
(3) Extruding die head part of PVC pipe production line: After compaction, melting, mixing and homogenization of PVC, there are subsequent materials pushed to the die head through the screw, and the extruding die head is the key component of pipe molding.
(4) PVC pipe production line vacuum shaping water tank is a mold with two cavities for pipe shaping and cooling, vacuum shaping water tank is equipped with vacuum system and water circulation system for shaping and cooling, stainless steel box, circulating water spray cooling, vacuum shaping water tank is equipped with forward and backward moving device and left and right, high and low adjusting manual device.
(5) The traction machine of PVC pipe production line is used to continuously and automatically lead the cooled and hardened pipes out from the head of the machine with frequency conversion.
(6) PVC pipe production line cutting machine: controlled by the travel switch according to the required length, it carries out automatic cutting, and delays the turning over of the frame, and implements the flow production, the cutting machine takes the signal of the fixed-length work switch as the instruction to complete the whole process of cutting, and keeps synchronization with the pipe running in the process of cutting, and the process of cutting is completed by the electric and pneumatic drive, and the cutting machine is equipped with the dust-absorbing device, so that the debris produced by the cutting can be timely suctioned out, and recycled. The cutting machine is equipped with a dust-absorbing device to suck out and recycle the chips produced by cutting in time.
(7) PVC pipe production line turning frame turning action by the cylinder through the air circuit control to achieve, turning frame is equipped with a limit device, when the cutting saw cut off the pipe, the pipe continues to transport, after a delay, the cylinder into the work, to achieve the turning action, to achieve the purpose of unloading. After unloading, it will be reset automatically after a delay of several seconds, waiting for the next cycle.
