Document Type and Number:
WIPO Patent Application WO/2024/087253
Kind Code:
A1
Abstract:
An extruder and an extrusion processing method, relating to the technical field of extruder devices. The extruder comprises a barrel (100) and a screw assembly; the screw assembly comprises a first screw (210) and a plurality of second screws (220), and the first screw (210) and the plurality of second screws (220) rotate in a same direction and are arranged in the barrel (100); the first screw (210) is meshed with the second screws (220), and meshing points are located on a plane formed by the rotation axes (230) of the first screw (210) and the second screws (220); the crest diameter of the first screw (210) is matched with the root diameters of the second screws (220) at the plane; the root diameter of the first screw (210) is matched with the crest diameters of the second screws (220) at the plane; the meshing points of the first screw (210) and the second screws (220) are always located in a plane formed by the two rotation axes, so that the maximum speed difference can be generated at the meshing points, thereby improving the meshing performance.
