The heat conduction mechanism is provided to rotate reversely with the feeding shaft, so that the raw materials inside the extrusion cylinder can be uniformly heated, thereby improving the extrusion effect and efficiency of the extrusion device. When in use, the raw materials pass from the feeding mechanism to the extrusion cylinder, and the heating mechanism heats the raw materials to make them into a molten state. The driving motor is started, and the driving motor drives the feeding shaft inside the extrusion cylinder to rotate to convey the raw materials. The rotation of the feeding shaft drives the first gear to rotate, the rotation of the first gear drives the second gear to rotate, and the rotation of the second gear drives the gear ring to rotate. The first gear and the gear ring rotate reversely, the gear ring drives the heat conduction mechanism to rotate, and the heat conduction mechanism rotates reversely with the feeding shaft to make the raw materials fully contact with the heat conduction mechanism. This solves the problem that the raw materials are easily accumulated under the extrusion cylinder due to gravity, resulting in uneven heating, longer melting time of the raw materials, and affecting the extrusion efficiency of the extrusion device.

[0004] However, the above-mentioned feeding mechanism is not provided with a mixing component, and it is difficult to completely break the agglomeration of the hollow fiber membrane raw materials during the subsequent melting process, resulting in uneven distribution of the filler.
