A chute is arranged in the unloading shaft 3, and a plurality of through holes are arranged in a circular array around the axis of the unloading shaft 3. Two sliders 301 are symmetrically arranged in the chute and slidably connected with the inner wall thereof. Each connecting rod 302 passes through the corresponding side through hole and is rotatably connected with the corresponding end of the tensioning plate 303 on the corresponding side. A bidirectional screw rod 304 is arranged in the chute and is rotatably connected with the unloading shaft 3. The sliders 301 on both sides are spirally connected with the corresponding ends of the bidirectional screw rod 304 respectively. A motor A305 is connected with the unloading shaft 3 and drives the bidirectional screw rod 304 to rotate. The structure of the reeling shaft 4 is the same as that of the unloading shaft 3. Two sets of support components are connected with the bottom plate 1, so as to support the unloading shaft 3 and the reeling shaft 4 at one end away from the vertical plate 2 respectively through the two sets of support components. The support component includes a support frame 6, and a card slot is arranged on the side of the support frame 6. The opening height of the card slot is the same as the diameter of the unloading shaft 3 and the reeling shaft 4. The tensioning plate 303 is located between the vertical plate 2 and the support frame 6. The sliding drive assembly includes a linear module 7, and two linear modules 7 are respectively driven to connect to the corresponding side support frame 6 to facilitate the replacement of the unwinding roller or the winding roller. The extruder head 9 is connected to the vertical plate 2 and is located between the unwinding shaft 3 and the winding shaft 4. Two sets of guide wheels 10 are connected to the vertical plate 2, and the two sets of guide wheels 10 are respectively located at both ends of the through hole of the extruder head 9. Two hydraulic cylinders 11 are arranged on the vertical plate 2, and the hydraulic cylinders 11 on both sides are respectively driven to connect to the corresponding side guide wheels to adjust the height of the corresponding side guide wheels to adapt to the cable core wires of different wire diameters and the finished cables after the cable sheath is coated, so that the central axis of the cable core and the cable after the sheath are in the same straight line with the center of the through hole of the extruder head 9.

[0028] Embodiment 2

[0030] In this embodiment, when the unwinding roller is replaced, the unwinding shaft 3 is easily bent due to the large weight of the new roller. Therefore, before installing the new roller, the unwinding roller is placed on the lifting support platform 8 below it, and the lifting support platform 8 is used to support it. After the support frame 6 corresponding to the unwinding shaft 3 slides to support the unwinding shaft 3, the support platform 8 can be lowered. Similarly, the operation of replacing the winding roller of the winding shaft 4 is the same. This structure can effectively prevent the unwinding shaft 3 and the winding shaft 4 from bending.

[0031] The implementation modes of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited thereto, and various changes can be made within the knowledge scope of technicians in the relevant technical field without departing from the purpose of the present invention.
