The present utility model discloses an extrusion mechanism for a co-rotating twin-screw extruder, comprising an extruder base; an extrusion device, the bottom of which is fixedly connected to the top of the extruder base; an extrusion housing, the side of which is fixedly connected to the side of the extrusion device; a screw, the end of which is rotatably connected to the inner surface of the extrusion device; and an electric telescopic rod, the side of which is fixedly connected to the side of the extrusion housing. In the above solution, by arranging the electric telescopic rod, movable cleaning plate, first cleaning brush, fixed cleaning plate and related structures, when plastic material enters the extrusion device and is extruded by the screw, residues attached to the surface of the screw can be cleaned by the first cleaning brush and the fixed cleaning plate to avoid accumulation on the screw surface. In this way, residues of plastic material are cleaned out in each extrusion operation, reducing manual cleaning of screw surface residues after work, simplifying the cleaning process and ensuring the subsequent processing progress of plastic materials.
