The present invention belongs to the technical field of twin-screw extruders, in particular to a twin-screw extruder comprising a base. An extrusion cylinder is fixedly connected to one side of the drive box on the base, and an extrusion rod is arranged in the extrusion cylinder. A threaded frame is slidably connected to one side of the sleeve wheel on the upper side of the bearing plate, and a fixing groove is fixedly connected to one side of the threaded frame. Two dismounting devices are arranged in the fixing groove, and the dismounting device comprises an upper fixing ring and a lower fixing ring arranged on one side of the threaded frame. The present invention lifts the dismounting device by starting an air cylinder, clamps and fixes the threaded sleeve through the upper fixing ring and the lower fixing ring, starts a first motor to rotate a first threaded rod to drive the threaded frame to slide on the bearing plate, and then drives the threaded sleeve to move through the dismounting device. The threaded sleeve drives the extrusion rod, extrusion block and push block to be taken out of the extrusion cylinder, reducing scalding of operators during manual disassembly and replacement of twin screws, and improving the work efficiency of disassembly and replacement of twin screws.
