[0031] In this embodiment, the first conveying pipe 8 and the second conveying pipe 10 are both heat-resistant pipes, which are heat-insulating and save energy and reduce consumption.

[0032] The working principle and use process of the utility model are as follows: when in use, the raw material enters the interior of the extrusion barrel 2 through the feed hopper 5, the fan 6 is started to suck the external gas into the interior of the heating box 7, and the heating tube 701 is energized, the heating tube 701 heats the gas, and the fan 6 blows the heated gas into the interior of the heating chamber 201 through the first conveying pipe 8, so that the raw material is heated while being conveyed, which is convenient for discharging the cable production raw material, avoiding the raw material agglomeration and sticking to the inner wall of the extrusion barrel 2, affecting the efficiency of subsequent work, and realizing full utilization of the raw material. The hot gas finally enters the interior of the feed hopper 5 through the heating chamber 201 and the second conveying pipe 10, which can preheat the raw material during feeding, thereby improving the subsequent heating speed, and finally the raw material is extruded through a plurality of extrusion holes 202. When the hand wheel 15 is turned, the hand wheel 15 drives the threaded rod 14 to rotate, and the connecting sleeve 13 drives the vertical plate 12 and the baffle 11 to move left and right, so that different numbers of extrusion holes 202 can be opened according to needs, and the raw material is extruded through different numbers of extrusion holes 202, which is further convenient for adjusting the extrusion speed of the raw material.
