The present utility model discloses a twin-screw extruder, comprising a twin-screw extruder main body. Positioning blocks clamped with positioning grooves are symmetrically and fixedly installed on the outer side of a heat dissipation fan, tension springs are symmetrically and fixedly installed on one side of the twin-screw extruder main body, and an insertion rod communicated with the positioning grooves is fixedly connected to one end of the two tension springs together. Both ends of the insertion rod are inserted into the positioning blocks. In the present utility model, the heat dissipation fan is placed inside a through hole and clamped by the positioning blocks and the positioning grooves. By pulling the insertion rod, the tension springs are stretched, so that both ends of the insertion rod are separated from the inside of the positioning blocks, thereby facilitating upward removal of the heat dissipation fan from the inside of the through hole. It solves the problem in the prior art that a heat dissipation fan is usually arranged at the tail of the twin-screw extruder to dissipate heat for the discharged material, but the heat dissipation fan is fixedly installed and inconvenient to disassemble, resulting in troublesome maintenance.
