A twin-screw extruder with an intermediate support structure comprises a barrel assembly, a pair of intermeshing twin-screw assemblies arranged in the barrel assembly, and a drive assembly for driving the twin-screw assemblies to rotate. The twin-screw assembly comprises a core shaft, the core shaft includes at least one support section and a plurality of thread sections, the support section is arranged in the middle of the core shaft, and thread sections are arranged on both sides of the support section on the core shaft. One end of the barrel assembly is provided with a feed inlet, and the other end is provided with a discharge outlet. A support assembly is fixed in the barrel assembly at a position corresponding to the support section between the feed inlet and the discharge outlet, and the support section of the core shaft is rotatably connected with the support assembly. Communication ports communicating with the inner cavity of the barrel assembly are respectively arranged on the barrel assembly near both ends of the support assembly, and the two communication ports on the barrel assembly are connected by a bypass pipe. In summary, the twin-screw extruder with an intermediate support structure provided by the device solution has the effect of reducing wear.
