Description

Technical Field

[0002] A plastic extruder for PVC plastic pellet production is a device used to extrude processed PVC plastic base material to produce plastic pellet products that meet the size and shape requirements. It is widely used in the field of plastic product processing. Extruders belong to the category of plastic machinery; they rely on the pressure and shearing force generated by the rotation of the screw to fully plasticize and uniformly mix the material, which is then shaped through a die.

[0003] The plastic extruder for producing PVC plastic particles described in patent CN220720217U can move the discharge nozzle to the front of the extrusion cylinder outlet by rotating the shift frame. The diameter of the extruded bar can be adjusted by using different sized discharge nozzles. By rotating the screw, four positioning frames are pushed against the surface of the discharge nozzle, and the discharge nozzle is connected to the outlet of the extrusion cylinder, so that the bar can be extruded from the discharge nozzle. However, when manufacturers process multiple products, although the diameter can be changed in the comparison file, it is not possible to output multiple products at once. Utility Model Content
