Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0027] Embodiment

[0028] Please refer to Figures 1 - 2 and Figures 5 - 8 The present invention provides the following technical solutions: A plastic protective film rewinding device includes a frame 1. A rewinding roller 7 is arranged at the front end of the frame 1. The rewinding roller 7 includes an adjusting component 8. A bearing 82 is movably sleeved inside the rewinding roller 7. One end of the bearing 82 extends to the outside of the rewinding roller 7 and is fixedly sleeved with a gear 81 and a cross handle 83. One end of the rewinding roller 7 is fixedly connected with a clamp seat 84. A second slide bar 87 is slidably connected inside the clamp seat 84. A second spring 86 is movably sleeved on the outer surface of the second slide bar 87. The bottom end of the second slide bar 87 is fixedly connected with a tongue 85. The bottom end of the tongue 85 meshes with the outer surface of the gear 81. Turntables 88 are fixedly sleeved at both ends of the bearing 82 inside the rewinding roller 7. A plurality of chutes 89 are opened inside the turntables 88. Slide bars 811 are movably connected inside the plurality of chutes 89. A plurality of connecting rods 810 are fixedly connected to the outer surface of the slide bars 811. One end of the plurality of connecting rods 810 penetrates through the side wall of the rewinding roller 7 and is fixedly connected with an arc plate 812.

[0029] Specifically, the staff first pulls up the second sliding rod 87. The second sliding rod 87 drives the tongue 85 away from the top tooth slot of the gear 81 and causes the second spring 86 to contract. Then, the staff rotates the cross-shaped knob 83. The cross-shaped knob 83 drives the bearing 82 to rotate. The bearing 82 drives the turntables 88 at both inner ends of the winding roller 7 to rotate. While the turntables 88 are rotating, the sliding rod 811 is driven to move through the sliding groove 89. The sliding rod 811 drives a plurality of connecting rods 810 to move outward from the winding roller 7. While the connecting rods 810 are moving, the arc-shaped plate 812 is driven to move. When the arc-shaped plate 812 moves to a suitable position, the second sliding rod 87 is released to allow the second spring 86 to rebound, causing the tongue 85 to re-enter the top tooth slot of the gear 81 to limit the gear 81. Thus, the purpose of adjusting the aperture size of the winding roller 7 is achieved, which can adapt to the winding requirements of plastic protective films with different widths and thicknesses, helps ensure the smoothness of the protective film during the winding process, reduces the generation of wrinkles and deviations, reduces the downtime and labor costs caused by equipment replacement or adjustment, and improves production efficiency.

[0030] Please refer to Figures 1 - 4 , the frame 1 includes a bearing component 4. One side of the frame 1 is movably connected to a bearing support 41. One side of the bearing support 41 is fixedly connected to a large sleeve 42. The inner wall of the large sleeve 42 is slidably connected to the outer surface of a small sleeve 43. One end of the small sleeve 43 is fixedly connected to the winding roller 7. The inner wall of the small sleeve 43 is slidably connected to the outer surface of a cross shaft 44. One end of the cross shaft 44 is fixedly connected to one side of the bearing support 41.

[0031] Specifically, when installing the winding roller 7, the staff first slidably sleeved the end of the winding roller 7 connected to the small sleeve 43 on the inner wall of the large sleeve 42 and inserted the cross shaft 44 into the small sleeve 43. This design provides a stable connection structure, reduces friction and wear between components, and thus extends the service life of the equipment.

[0032] Please refer to Figures 3 - 4 , a limit support 48 is fixedly installed on the top of the large sleeve 42. A first sliding rod 45 is slidably connected inside the limit support 48.

[0033] Specifically, the limit support 48 can accurately set the movement range of the first sliding rod 45 to ensure that the first sliding rod 45 moves within a predetermined trajectory and avoid exceeding the safe or effective working area.

[0034] Please refer to Figures 3 - 4 , a first spring 47 is movably sleeved on the outer surface of the first sliding rod 45. The top of the first spring 47 is fixedly connected to the limit support 48. The bottom of the first spring 47 is fixedly connected to a limit ring 46.

[0035] Specifically, the design of the first spring 47 provides a certain adjustment space for the first sliding rod 45, enabling the first sliding rod 45 to move freely within a certain range when subjected to an external force, and at the same time, it can quickly return to its original position through the elastic force of the first spring 47, enhancing the adaptability and flexibility of the device.

[0036] Please refer to Figures 3 - 4 , the limiting ring 46 is fixedly sleeved on the outer surface of the first sliding rod 45, and the bottom end of the first sliding rod 45 penetrates through the top of the small sleeve 43 and is fitted into the notch at the top end of the cross shaft 44.

[0037] Specifically, through the elastic force of the first spring 47, the limiting ring 46 can make the bottom end of the first sliding rod 45 slide through the notch at the top of the small sleeve 43 and move to the notch at the top of the cross shaft 44, thereby limiting and fixing the small sleeve 43, preventing the winding roller 7 from falling off during rotation, making the disassembly and assembly process simple and fast, improving the overall reliability and stability of the device, and ensuring the smooth progress of the plastic protective film unrolling process.

[0038] Please refer to Figure 1 , a hydraulic rod 2 is fixedly installed at the top of the rear wall of the frame 1, and the output shaft of the hydraulic rod 2 is fixedly connected to a blade 3.

[0039] Specifically, the hydraulic rod 2 is used to provide power for the movement of the blade 3, enabling the blade 3 to move up and down, thereby achieving the purpose of cutting the film.

[0040] Please refer to Figure 1 , a motor bracket 6 is fixedly connected to one side of the frame 1. A motor 5 is fixedly installed in the middle and at the top of the motor bracket 6 respectively. The output shaft of the motor 5 penetrates through the side wall of the frame 1 and is fixedly sleeved with a bearing assembly 4.

[0041] Specifically, the motor bracket 6 can fixedly support the motor 5, enabling the motor 5 to transmit power better.

[0042] Working principle and usage process of the present utility model: During the use of the present utility model, when the staff needs to adjust the aperture size of the winding roller 7, the staff first pulls up the second sliding rod 87. The second sliding rod 87 drives the tongue 85 to leave the top tooth groove of the gear 81 and causes the second spring 86 to contract. Then the staff rotates the cross-shaped handle 83. The cross-shaped handle 83 drives the bearing 82 to rotate. The bearing 82 drives the turntables 88 at both ends inside the winding roller 7 to rotate. While the turntables 88 are rotating, they drive the sliding rod 811 to move through the sliding groove 89. The sliding rod 811 drives a number of connecting rods 810 to move outward from the winding roller 7. While the connecting rods 810 are moving, they drive the arc-shaped plate 812 to move. When the arc-shaped plate 812 moves to the appropriate position, the second sliding rod 87 is released to make the second spring 86 rebound, so that the tongue 85 re-enters the top tooth groove of the gear 81 to limit the gear 81, thereby achieving the purpose of adjusting the aperture size of the winding roller 7, being able to adapt to the winding requirements of plastic protective films with different widths and thicknesses, helping to ensure the smoothness of the protective film during the winding process, reducing the generation of wrinkles and deviations, reducing the downtime and labor costs caused by equipment replacement or adjustment, and improving production efficiency. When the staff needs to install the winding roller 7, the staff first pulls up the first sliding rod 45 to make the first sliding rod 45 leave the inside of the large sleeve 42 and contract the first spring 47 through the limiting ring 46. Then the staff slides the end of the winding roller 7 connected to the small sleeve 43 onto the inner wall of the large sleeve 42 and makes the cross shaft 44 fit into the inside of the small sleeve 43. Then the staff releases the first sliding rod 45 to make the first spring 47 rebound. The first spring 47 drives through the limiting ring 46 to make the bottom end of the first sliding rod 45 penetrate through the top notch of the small sleeve 43 and move to the top notch of the cross shaft 44, thereby achieving the purpose of quickly installing the winding roller 7, making the disassembly and assembly process simple and fast, providing a stable connection structure, reducing the friction and wear between components, improving the overall reliability and stability of the equipment, and ensuring the smooth progress of the plastic protective film winding process.

[0043] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments or perform equivalent replacements for some of the technical features. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
