The present invention discloses an inner hole processing device for a gate valve cylinder of a twin-screw extruder, applied to the technical field of twin-screw extruder processing. In the present invention, a sliding push plate slides on an inclined surface at the bottom of a lifting block, so that the lifting block can overcome the elastic force of a return spring to move up and down, a grinding wheel head is attached to the inner hole of the gate valve cylinder of a twin-screw extruder, and the grinding wheel head is driven to rotate for grinding processing, so that the grinding thrust of the grinding wheel can be accurately controlled and the accuracy of the processing size of the inner hole of the gate valve cylinder of a twin-screw extruder is improved; by starting a second motor to drive a rotating shaft to rotate, a dust blowing fan on the surface of the rotating shaft is rotated to blow air, so that debris and dust ground by the grinding wheel head from the inner hole of the gate valve cylinder of a twin-screw extruder can be blown out, avoiding debris accumulation in the inner hole causing abrasion to the gate valve cylinder of a twin-screw extruder and improving the grinding precision of the inner hole.
