Extrusion mechanism of co-rotating twin-screw extruder

The utility model discloses an extrusion mechanism of a co-rotating twin-screw extruder. The extrusion mechanism comprises an extruder base, the bottom of the extrusion device is fixedly connected with the top of the extruder base; the side surface of the extrusion shell is fixedly connected with the side surface of the extrusion device; the end part of the screw rod is rotationally connected with the inner surface of the extrusion device; and the side face of the electric telescopic rod is fixedly connected with the side face of the extrusion shell. According to the scheme, by arranging related structures of the electric telescopic rod, the movable cleaning plate, the first cleaning brush and the fixed cleaning plate, when plastic substances enter the extrusion device and are extruded through the screw, residues attached to the surface of the screw can be cleaned through the first cleaning brush and the fixed cleaning plate, and accumulation on the surface of the screw is avoided; therefore, during each extr
