[0022] In the following description, many specific details are set forth in order to fully understand the present utility model. However, the present utility model can also be implemented in other ways different from those described herein. Therefore, the present utility model is not limited by the specific embodiments disclosed in the following specification.

[0023] Embodiment 1

[0024] Please refer to Figures 1-4, the present utility model provides a technical solution: a stretching film winding device, including a base 1, a winding drum 11 and an unwinding roller 12. On the surface of the base 1, a side frame A2 is fixedly installed. On the surface of the side frame A2, a motor A3 is fixedly installed. The output end of the motor A3 is equipped with a rotating plate 4. Inside the rotating plate 4, a clamping groove 5 is formed. Inside the rotating plate 4, a sliding rod 6 is slidably connected. A spring 7 is sleeved on the surface of the sliding rod 6. One end of the spring 7 is connected to the inner surface of the rotating plate 4, and the other end is connected to the surface of a clamping block 8. The design of the spring 7 serves to drive the clamping block 8 to engage into the clamping groove 5, thereby fixing the insertion block 9 inside the rotating plate 4. A clamping block 8 is fixedly installed on the surface of the sliding rod 6. The clamping block 8 is slidably connected with the clamping groove 5. An insertion block 9 is inserted into the rotating plate 4. The surfaces of both the clamping block 8 and the insertion block 9 are arc-shaped. The arc-shaped design of the clamping block 8 and the insertion block 9 serves to facilitate the quick installation of the winding drum 11. The insertion block 9 is slidably connected with the rotating plate 4. A limiting block 10 is fixedly installed on the surface of the insertion block 9. The limiting block 10 is slidably connected with the winding drum 11. The sliding design between the limiting block 10 and the winding drum 11 serves to facilitate the disassembly and assembly of the winding drum 11, thereby improving the efficiency of disassembling and assembling the winding drum 11. On the surface of the base 1, a side frame B13 is fixedly installed. On the surface of the side frame B13, a motor B14 is fixedly installed. The output end of the motor B14 is equipped with a lead screw 19. Inside the side frame B13, a limiting plate 15 is slidably connected. An electric push rod 16 is fixedly installed on the surface of the limiting plate 15. The output end of the electric push rod 16 is equipped with a pressing plate 17. The pressing plate 17 is slidably connected with the limiting plate 15. The sliding design between the pressing plate 17 and the limiting plate 15 serves to limit the pressing plate 17 when the pressing plate 17 moves. Inside the pressing plate 17, a roller 18 is rotatably connected.

[0025] Embodiment Two

[0026] Please refer to Figures 1-4 , a rotating block 20 is rotatably connected to the surface of the unwinding roller 12. Inside the base 1, a cylinder 21 is fixedly installed. The output end of the cylinder 21 is equipped with a support 22. The design of the cylinder 21 and the support 22 serves to facilitate the lifting of the unwinding roller 12. The number of the cylinder 21 and the support 22 is two groups. The two groups of the cylinder 21 and the support 22 are symmetrically distributed on both sides of the base 1. The symmetrical design of the cylinder 21 and the support 22 serves to facilitate the disassembly, assembly and replacement of the unwinding roller 12, improving the replacement efficiency of the unwinding roller 12 and also improving the winding efficiency of the stretching film.

[0027] Working principle: When using the rewinding device, first turn on the motor A3. The motor A3 drives the rotating plate 4 to rotate. The rotating plate 4 drives the limiting block 10 and the winding drum 11 to rotate. When the winding drum 11 rotates, it winds the stretch film. When it is necessary to adjust the tension of the stretch film, just turn on the motor B14. The motor B14 drives the lead screw 19 to rotate. When the lead screw 19 rotates, it drives the limiting plate 15 to move. When the limiting plate 15 moves, it tightens the stretch film. When it is necessary to disassemble the winding drum 11, just dial the clamping block 8. After the clamping block 8 slides out of the clamping groove 5, the winding drum 11 together with the limiting block 10 and the inserting block 9 can be pulled out from the rotating plate 4. The spring 7, the sliding rod 6, the clamping block 8, the inserting block 9 and the limiting block 10 facilitate the quick disassembly and assembly of the winding drum 11, thus avoiding the situation of using disassembly tools to disassemble the winding drum 11 during disassembly and assembly, improving the efficiency of replacing the winding drum 11 and at the same time improving the efficiency of winding the stretch film. When it is necessary to replace the unwinding roller 12, just turn on the cylinder 21. The cylinder 21 drives the bracket 22 to move downward. At this time, the unwinding roller 12 moves downward under the action of gravity. After the unwinding roller 12 touches the bottom plate, the unwinding roller 12 can be removed from the base 1. Then move the new unwinding roller 12 above the bracket 22, and then raise the bracket 22 through the cylinder 21. The bracket 22 raises the unwinding roller 12 through the rotating block 20. After the unwinding roller 12 is raised, the replacement of the unwinding roller 12 is completed. The cylinder 21, the rotating block 20 and the bracket 22 play the role of lifting the unwinding roller 12, thus facilitating the replacement of the unwinding roller 12 and avoiding the situation of using lifting equipment when replacing the unwinding roller 12, improving the efficiency of replacing the unwinding roller 12 and at the same time improving the efficiency of winding the stretch film.

[0028] The above are only the preferred embodiments of the present invention, and are not intended to limit the present invention in other forms. Any person skilled in the art may use the disclosed technical content to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields. However, as long as it does not depart from the technical content of the technical solution of the present invention, any simple modification, equivalent change and modification made to the above embodiments according to the technical essence of the present invention still fall within the protection scope of the technical solution of the present invention.
