[0020] Furthermore, the technical features involved in the different embodiments of this application described below can be combined with each other as long as they do not conflict with each other.

[0021] This application provides a low-tension winding machine, as referenced. Figures 1 to 7 ,include: Drum 12, tapered shaft 14, reducer 17, motor 18, among which, The drum 12 is connected to the tapered shaft 14 via a connector 13. The tapered shaft 14 is connected to the output shaft of the reducer 17 via a bearing seat 16. The reducer 17 is connected to the motor 18 and is mounted on the same base. The drum 12 includes a sector block 1, a pyramidal shaft 3, a hollow shaft 5, a reducer 17, a guide key 7, and an expansion cylinder 9. The sector block 1 is connected to the pyramidal shaft 3 via a T-key 10. A copper backing plate 2 is provided between the sector block 1 and the pyramidal shaft 3. The sector block 1 and the hollow shaft 5 are connected by a slider 4. The hollow shaft 5 is connected to the reducer 17. The guide key 7 is connected to the pyramidal shaft 3. The pyramidal shaft 3 is connected to the expansion cylinder 9 via a connecting seat 8.

[0022] Specifically, sector block 1 is connected to pyramidal shaft 3 via T-key 10. A copper backing plate 2 is provided between sector block 1 and pyramidal shaft 3 to reduce friction during axial movement of pyramidal shaft 3. Slider 4 connects sector block 1 and hollow shaft 5, allowing sector block 1 to move axially while also expanding and contracting radially. Hollow shaft 5 is connected to reducer 17, allowing the rotation of gears in reducer 17 to transmit rotational power to hollow shaft 5. Simultaneously, guide key 7 is connected to pyramidal shaft 3, enabling sector block 1 and pyramidal shaft 3 to perform circular motion.

[0025] Specifically, the drum 12 and the conical shaft 14 are connected by a connector 13 to transmit power, and the drum 12 and the conical shaft 14 are pressed together by a locking nut 11. The mating surface between the conical shaft 14 and the drum 12 is conical, which facilitates easy unwinding of the strip by the unwinder 15, allowing it to easily push the strip and the drum 12 out of the conical shaft 14. The unwinder 15 is mounted on a bearing seat 16, and the conical shaft 14 is connected to the output shaft of the reducer 17 through the bearing seat 16, allowing the reducer 17 to directly transmit rotational power to the conical shaft 14.

[0029] In some embodiments, the copper liner 2 is disposed on the end face of the protrusion away from the pyramidal axis 3, and the side liner is disposed on the two side surfaces of the protrusion.

[0030] In some embodiments, both the sector block 1 and the jaw sector block 1 are connected to the pyramidal shaft 3 via a T-key 10. Both the jaw sector block 1 and the sector block 1 are connected to the hollow shaft 5 via a guide key 7.

[0031] In some embodiments, the guide key 7 has T-shaped tenons at both ends, the clamping fan block 1 and the right end of the fan block 1 have a first mortise, the hollow shaft 5 has a second mortise at the left end, and the T-shaped tenons at both ends of the guide key 7 are coupled to the first mortise and the second mortise, respectively.
