The invention discloses a twin-screw extruder, relating to the technical field of electrode preparation. It comprises a discharge head, an extrusion cavity for extruding mixed materials is arranged in the discharge head, a cooling jacket is sleeved on the outer peripheral side of the discharge head, a cooling channel for the circulation of cooling medium is arranged in the cooling jacket, an inlet and an outlet are respectively formed on the side wall of the cooling jacket, the inlet is communicated with one end of the cooling channel, and the outlet is communicated with the other end of the cooling channel. By arranging the cooling jacket on the outer wall of the discharge head with a cooling channel for cooling medium circulation, cooling medium is introduced from the inlet when the twin-screw extruder is working, and the cooling medium passes through the cooling channel and the outlet in turn to cool the discharge head, thereby cooling the mixed materials and preventing the binder in the mixed materials from failing due to excessive temperature.
