Description

Technical Field

[0001] This utility model relates to the field of extruder technology, specifically to a discharge mechanism for a PVC granule extruder that facilitates material discharge. Background Technology

[0002] Extruders can be categorized by the angle between the material flow direction at the die head and the screw centerline, such as right-angle die heads and angled die heads. Screw extruders rely on the pressure and shear force generated by the rotating screw to fully plasticize and uniformly mix materials, which are then shaped through a die. Plastic extruders can be broadly classified into twin-screw extruders, single-screw extruders, and less common multi-screw extruders and screwless extruders. Currently, existing extruders require continuous manual filling by the user, which can easily lead to material accumulation at the feed inlet and uneven filling, resulting in inconsistent extruder efficiency. Utility Model Content

Simultaneously, the user controls the moving structure to drive the sealing structure to block the outlet of the feed hopper. The user then adjusts the partition plate to allow the material accumulated on the partition plate to enter the shell, where it is preheated.
