The device is not convenient to adjust the spacing of the upper limit structure of the sleeve shaft, which makes it difficult for the device to wind up wrapping film of different widths, thereby reducing the versatility of the device.

[0004] To address the aforementioned issues, there is an urgent need for innovative designs based on the existing anti-winding mechanism for stretch film. Utility Model Content

[0005] The purpose of this invention is to provide a wrapping film rewinding mechanism to solve the problem mentioned in the background art that the existing wrapping film rewinding mechanism is inconvenient to adjust the spacing of the upper limit structure of the sleeve shaft, which makes it difficult for the device to wind up wrapping films of different widths, thereby reducing the versatility of the device.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Please see Figures 1-4 This utility model provides a technical solution: a wrapping film rewinding mechanism, including a base plate 1, an adjusting motor 2, a support rod 3, a positioning ring 4, a transmission plate 5, a winding motor 6, a limiting base 7, a knob 8, a positioning square post 9, a sleeve shaft 10, a positioning rod 11, a limiting sleeve 12, a top plate 13, a locking mechanism 14, a locking rod 1401, a clamping plate 1402, and an anti-slip pad 1403. The adjusting motor 2 is installed in the middle of the upper surface of the base plate 1, and the support rods 3 are fixed at both ends of the upper surface of the base plate 1, and the positioning ring 4 is fixedly provided at the upper end of the support rod 3. A transmission plate 5 is connected to the upper surface of the transmission plate 5, and a winding motor 6 is installed at the edge of the upper surface of the transmission plate 5. The upper end of the output shaft of the winding motor 6 is fixedly connected to a limiting base 7, and a knob 8 is provided on the inner wall of the side of the limiting base 7. A positioning column 9 is installed on the inner wall in the middle of the limiting base 7, and a sleeve shaft 10 is fixedly connected to the upper end face of the positioning column 9. A positioning rod 11 is fixedly installed on the upper end face of the sleeve shaft 10. A limiting sleeve 12 is sleeved on the outer wall of the positioning rod 11, and a top plate 13 is fixedly connected to the upper end face of the positioning rod 11. Locking mechanisms 14 are provided on the inner walls of both ends of the top plate 13.

[0017] The output shaft of the adjusting motor 2 is fixedly connected to the transmission plate 5, and the transmission plate 5 and the positioning ring 4 form a rotating structure, which makes it easy for the adjusting motor 2 to drive the transmission plate 5 to rotate stably relative to the positioning ring 4, thereby adjusting the position of the sleeve shaft 10.

[0018] The limiting base 7 and the positioning column 9 are slidably arranged, and both the limiting base 7 and the positioning column 9 are threadedly connected to the knob 8. The limiting base 7 and the sleeve shaft 10 are in contact, which makes it easy to rotate the knob 8 so that the knob 8 can be disengaged from the positioning column 9, thereby making it convenient for the user to move and disassemble the sleeve shaft 10.

[0019] The sleeve shaft 10 and the limiting sleeve 12 form a sliding structure, and the limiting sleeve 12 and the positioning rod 11 are threaded together, which makes it easy for the user to rotate the limiting sleeve 12 so that the limiting sleeve 12 moves relative to the positioning rod 11 and the sleeve shaft 10, thereby adjusting the distance between the limiting sleeve 12 and the limiting base 7. At this time, the distance of the upper limit structure of the sleeve shaft 10 is adjusted, making the device easy to adapt to different widths of wrapping film for use.

[0020] The locking mechanism 14 includes a locking rod 1401, a clamping plate 1402, and an anti-slip pad 1403. The locking rod 1401 is movably installed on the inner wall of the top plate 13, and the clamping plate 1402 is rotatably installed on the lower end of the locking rod 1401. The anti-slip pad 1403 is adhered to the lower surface of the clamping plate 1402, which facilitates the locking mechanism 14 to limit the adjusted limiting sleeve 12, thereby ensuring the stability of the limiting sleeve 12.

[0021] The locking rod 1401 is threadedly connected to the top plate 13, and the anti-slip pad 1403 is fitted to the limiting sleeve 12. This allows the user to rotate the locking rod 1401 so that it moves relative to the top plate 13, thereby moving the clamping plate 1402 so that the anti-slip pad 1403 is tightly attached to the limiting sleeve 12, thus completing the limiting of the limiting sleeve 12.

[0022] Working principle: When using this wrapping film rewinding mechanism, firstly as follows... Figures 1-4 As shown, the user fixes the base plate 1 in the working position, and then adjusts the position of the sleeve shaft 10 according to the requirements. At this time, the user starts the adjustment motor 2, which drives the transmission plate 5 to rotate relative to the positioning ring 4. Subsequently, the transmission plate 5 drives the sleeve shaft 10 to rotate for position adjustment. After the position of the sleeve shaft 10 is adjusted, the user adjusts the spacing of the upper limit structure of the sleeve shaft 10 according to the width of the wrapping film, that is, adjusts the spacing between the limiting sleeve 12 and the limiting base 7. Then, the user rotates the limiting sleeve 12, which moves relative to the positioning rod 11 and slides relative to the sleeve shaft 10. As the limiting sleeve 12 moves, the spacing between the limiting sleeve 12 and the limiting base 7 is adjusted. Therefore, the device facilitates the adjustment of the spacing of the upper limit structure of the sleeve shaft 10, thereby facilitating the winding of wrapping films of different widths and improving the versatility of the device. After the position of the limiting sleeve 12 is adjusted, the user rotates the locking rod 1401, which then moves relative to the top plate 13. Next, the locking rod 1401 drives the clamping plate 1402 to move, and then the clamping plate 1402 drives the anti-slip pad 1403 to move, so that the anti-slip pad 1403 is in close contact with the limiting sleeve 12, thereby completing the limiting of the limiting sleeve 12 and preventing the limiting sleeve 12 from loosening during the operation of the device. Then, the user installs the stretch film on the sleeve shaft 10 and starts the winding motor 6 to drive the sleeve shaft 10 to rotate, thereby completing the winding of the stretch film. After the stretch film is wound up, the user turns off the winding motor 6 and rotates the knob 8. Then, the knob 8 moves relative to the limiting base 7 and disengages from the positioning column 9. Next, the user moves the sleeve shaft 10 so that the sleeve shaft 10 drives the positioning column 9 to disengage from the limiting base 7, thereby completing the unloading of the roll of stretch film.

[0023] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
