[0002] The fiber spinning screw structure is mainly used to send the material to the heating zone by rotating the screw with spiral blades during operation, and then send it to the metering pump after extrusion and melting. The metering pump ensures that the polymer melt flows steadily into the spinning box, and after being filtered in the box, it is pressed into the porous spinneret to spray out the melt stream, and then quickly condensed by cold air to form a solidified tow fiber.

[0009] As an improvement of the above technical solution: the rod body, the heat-conducting tube and the annular heat-conducting block are all made of aluminum or copper.

[0010] Beneficial effects of the utility model:

[0011] Specifically, when the material is transported by the present application, the drive motor and the electric heating tube are started, the heat emitted by the electric heating tube is absorbed by the heat-conducting tube, and the heat-conducting tube is driven to rotate by the drive motor, and the outer side of the heat-conducting tube can be evenly contacted with the inner side of the rod body, so that the heat absorbed by the heat-conducting tube is evenly transferred to the rod body, so that the material transported outside the rod body can be evenly heated;

[0012] At the same time, the exhaust fan is started, and an air duct can be formed by multiple annular heat-conducting blocks arranged inclined toward each other, so that part of the flow rate can be dissipated to various positions inside the heat-conducting tube through the axial direction of the annular heat-conducting block, and the heat dissipated from the surface of the electric heating tube can be more evenly dissipated to the heat-conducting tube with the cooperation of the annular heat-conducting block and the flow rate, and then uniformly absorbed by the rod body, so that the heat dissipated from part of the electric heating tube can pass through the annular heat-conducting block and then through the first through hole and the connecting port into the flow cavity inside the spiral piece, thereby effectively heating the spiral piece, so that the material during transportation can be quickly and effectively heated by the rod body and the spiral piece, thereby improving the overall transportation efficiency.
