Extruder part: This machine has a quantitative feeding device to match the extrusion volume with the feeding volume to ensure stable extrusion of the product. Due to the use of conical twin screws, the feeding section has a larger diameter, so the heat transfer area and shear speed of the material are relatively large, which is conducive to the plasticization of the material. The screw diameter of the metering section is small, which reduces the heat transfer area and the opposite. The shear speed of the melt enables the melt to be extruded at a lower temperature.
Extrusion die head part:The PVC that is compacted, melted, mixed and homogenized, and the subsequent materials are pushed to the die head by the screw. The extrusion die head is the key part of the pipe forming.
The cooling device part of the vacuum setting table: it is composed of a water tank, a frame, an up and down, left and right adjustable lifting mechanism, a stainless steel water tank and a stainless steel vacuum box. The function of the vacuum setting table is to stabilize the predetermined shape of the plastic extruded from the die and finish it, so as to obtain products with a larger cross-sectional size and a brighter surface. The cooling setting device of the vacuum setting table not only determines the product The dimensional accuracy is also an important factor affecting the extrusion speed.
Haul Off Machine part with dopts frequency conversion speed regulation, which is used to continuously and automatically draw the cooled and hardened profile from the nose, saving energy, stable and durable.
Cutting machine part: The request made by the stroke length of the control switch, the automatic cutting and turning frame delay, implementation of water production, a constant cutter permanent switching instruction signal, to complete the whole process of cutting, synchronized with the profile running in the cutting process, the cutting process It is driven by electric and pneumatic.
Part of the turning frame: the turning action is realized by the pneumatic control of the cylinder. The turning frame has a limit device. When the cutting saw cuts the profile,it will continue to convey the profile. After a delay, the cylinder enters the work to realize the turning action. ,To achieve the purpose of unloading. After unloading, it will automatically reset after a few seconds delay, and wait for the next cycle.
