[0029] In this embodiment, an extension seat is fixedly connected to one end of the take-up seat 2 and one side of the top of the support plate 7. The take-up motor 4 and the unwind motor 9 are bolted to one end of the extension seat. By using the extension seat, the take-up motor 4 and the unwind motor 9 can be stably assembled, ensuring the transmission effect of the take-up motor 4 and the unwind motor 9.

[0030] The traction assembly 6 includes a displacement frame 13, a traction roller 14, a guide column 15, a support shaft 16, and a guide plate 17. The top and bottom ends of one side of the traction seat 5 are slidably connected to the displacement frame 13. The ends of the two displacement frames 13 that are far apart from each other are rotatably connected to the traction roller 14. The ends of the displacement frames 13 that are far away from the traction roller 14 are fixedly connected to the guide column 15. The middle of the traction seat 5 is rotatably connected to the support shaft 16. One end of the support shaft 16 is fixedly connected to the guide plate 17. The top and bottom ends of the guide plate 17 are provided with guide slots 18. The two guide columns 15 are also movably connected inside the guide slots 18. The other side of the traction seat 5 is fixedly connected to a drive motor 19. The output end of the drive motor 19 is fixedly connected to a drive spur gear 20.

[0031] In this embodiment, the ends of the two displacement frames 13 that are far apart from each other are fixedly connected to support ears, and the traction roller 14 is connected to the support ears through ball bearings. The support ears can effectively support the traction roller 14, and the ball bearings can ensure the smoothness of the connection between the traction roller 14 and the support ears.

[0032] Example 2:

[0033] Please see Figure 1-5This embodiment provides a technical solution based on Embodiment 1: The positioning component 10 includes an assembly plate 22, a positioning plate 23, a positioning shaft 24, a positioning frame 25, and a displacement plate 26. One end of the winding shaft 3 and the unwinding shaft 8 are fixedly connected to the assembly plate 22. Multiple positioning plates 23 are fixedly connected to the outer side of the assembly plate 22. A positioning shaft 24 is rotatably connected to each positioning plate 23. A positioning frame 25 is fixedly connected to the outer side of the positioning shaft 24. A displacement plate 26 is slidably connected to one side of the assembly plate 22. A linkage rod 27 corresponding to the positioning shaft 24 is rotatably connected to the outer side of the displacement plate 26. The end of the linkage rod 27 away from the displacement plate 26 is also rotatably connected to the corresponding positioning frame 25. A transmission screw 28 is rotatably connected to the side of the assembly plate 22 close to the displacement plate 26. The displacement plate 26 is also threadedly connected to the outer side of the transmission screw 28.

[0034] In this embodiment, a plurality of assembly pins are fixedly connected to the side of the assembly plate 22 away from the displacement plate 26, and an assembly hole adapted to the assembly pin is opened at one end of the take-up roller 11 and the unwind roller 12. By using the assembly pins and assembly holes, before the take-up roller 11 or the unwind roller 12 is assembled, the assembly hole is first aligned with the assembly pin, and the take-up roller 11 or the unwind roller 12 is pushed, so that the take-up roller 11 or the unwind roller 12 can be sleeved on the outside of the assembly pin, thereby achieving the initial locking of the take-up roller 11 or the unwind roller 12.

[0035] In this embodiment, the positioning frame 25 has an L-shaped structure. The end of the positioning frame 25 away from the positioning plate 23 is provided with anti-slip texture. Utilizing the structural characteristics of the positioning frame 25, after the positioning frame 25 is flipped, it can block the take-up roller 11 or the unwind roller 12, preventing the take-up roller 11 or the unwind roller 12 from disengaging from the assembly pin.

[0036] In this embodiment, a positioning pin is provided in the middle of one side of the positioning frame 25, and the end of the linkage rod 27 away from the displacement disk 26 is rotatably connected to the positioning pin. By using the positioning pin, the linkage rod 27 can be stably connected between the positioning pin and the displacement disk 26, ensuring the application effect of the linkage rod 27.

[0037] In this embodiment, a stabilizing slide rod is fixedly connected to the side of the assembly plate 22 near the displacement plate 26, and the displacement plate 26 is also slidably connected to the outside of the stabilizing slide rod.

[0038] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0039] Working principle: First, the unwinding roller 12 is attached to the mounting plate 22 at the unwinding shaft 8. Then, the transmission screw 28 is rotated to connect with the displacement plate 26, so that the displacement plate 26 can move along the transmission screw 28. Since the linkage rod 27 is connected between the displacement plate 26 and the positioning frame 25, when the displacement plate 26 moves, the linkage rod 27 can push the positioning frame 25 to rotate under the support of the positioning shaft 24 until the positioning frame 25 is adjusted to be perpendicular to the unwinding roller 12, thus locking the position of the unwinding roller 12. Then, the take-up roller 11 is assembled on the mounting plate 22 at the take-up shaft 3 according to the above steps.

[0040] The knitted fabric at the unwind roller 12 is released, and after passing one side of one pull roller 14 and the other side of the other pull roller 14, it is connected to the take-up roller 11. Then, the unwind motor 9 is started to release the knitted fabric at the unwind roller 12 at a uniform speed, and the take-up motor 4 is started to drive the take-up roller 11 to rotate and roll up the knitted fabric. Before the knitted fabric is rolled up, the pull roller 14 can be used to pull the knitted fabric to enhance the moisture absorption and breathability of the knitted fabric. The transmission motor 19 can be started to cause the transmission spur gear 20 to move the reduction spur gear 21, thereby driving the guide plate 17 to rotate. Since the two guide posts 15 are respectively connected inside the two guide slots 18, when the guide plate 17 rotates, it can push the two guide posts 15 through the two guide slots 18, thereby driving the two displacement frames 13 to move towards each other, adjusting the distance between the two pull rollers 14, thereby controlling the pulling force of the pull rollers 14.

[0041] Furthermore, after pulling, the take-up roller 11 and the unwind roller 12 can be disassembled by rotating the transmission screw 28, which greatly improves the overall convenience.

[0042] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.

[0043] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
