[0002] A protective film generally refers to a plastic film coil, such as a glass protective film pasted on glass for dust and explosion prevention, which is mostly used on glass doors, windows and vehicle window glasses. When the glass protective film leaves the factory, the protective film reel is generally long, which is convenient for later cutting to adapt to different products. In the sales link, salespersons often need to unfold the protective film to show the product quality to customers. After the display, the salesperson also needs to manually rewind the unfolded protective film. In actual use, the construction workers pasting the protective film also need to unfold a protective film with an area larger than the product to be pasted, so as to cut the protective film according to the actual product. After cutting, the construction workers also need to manually rewind the unfolded protective film.

[0034] As Figures 1 to 6As shown in the figure, an embodiment of the present utility model provides a protective film winding device, which includes a carrying base 1, a pair of support components 2, and a flattening component 3 installed on one side of the support components 2. The carrying base 1 forms a U-shaped bracket structure. The protective film roll 4 is rotatably installed inside the carrying base 1 through the support components 2, which is convenient for displaying the protective film. At the same time, the flattening component 3 is rotatably installed inside the carrying base 1, which is convenient for pressing the side wall of the protective film roll 4, so as to avoid wrinkles in the protective film during winding and affect the quality of the protective film. The flattening component 3 can also be used as a handle to lift the device. The overall structure of the device is simple, small in size, and convenient to carry.

[0035] As Figures 1 to 3 shown, the carrying base 1 includes a seat plate 5. A lightweight groove 6 is opened at the top of the seat plate 5, which can reduce the weight of the seat plate 5, reduce the carrying burden, and further facilitate carrying. At the same time, it can save materials and reduce production costs. Both ends of the top of the seat plate 5 are fixedly connected with support plates 7. The support plates 7 are vertically distributed with the seat plate 5. Reinforcing ribs can also be provided at the connection between the support plates 7 and the seat plate 5 to enhance the stability of the support plates 7. A first assembly hole 8 is opened on the side wall of the support plate 7, and a second assembly hole 9 is opened on one side of the first assembly hole 8. The second assembly hole 9 is usually located slightly above the center of the first assembly hole 8, which is convenient for the flattening component 3 to generate pressure on the protective film roll 4 when rotating, so as to realize the flattening effect of the flattening component 3 on the protective film roll 4.

[0036] As Figure 2 、 Figure 4 and Figure 5As shown, the support assembly 2 includes a support screw 10 adapted to the first assembly hole 8, the support screw 10 passes through the first assembly hole 8 and is rotatably connected to the support plate 7, one end of the support screw 10 is fixedly connected to a turntable 11, and the side wall of the other end of the support screw 10 is provided with a thread, and the threaded end faces the inside of the bearing base 1, the support assembly 2 also includes a support head 12 sleeved on the threaded end of the support screw 10, the support head 12 is threadedly connected to the support screw 10, the support head 12 includes a connecting portion 15 in a straight cylinder structure, and the inner side wall of the connecting portion 15 is provided with a thread adapted to the threaded end of the support screw 10, one end face of the connecting portion 15 is fixedly connected to a curved cylinder, the curved cylinder includes a first expansion portion 16 away from the connecting portion 15 and a second expansion portion 17 close to the connecting portion 15, the first expansion portion The maximum outer diameter of 16 is smaller than the maximum outer diameter of the second expansion portion 17, and a plurality of groups of scaling grooves 18 are evenly arranged on the side wall of the curved tube. By setting the support head 12, when in use, the support head 12 screwed to the support screw 10 can be adjusted to a position on the support screw 10, so as to be convenient for adapting to the use of protective film rolls 4 of different lengths. The first expansion portion 16 and the second expansion portion 17 arranged on the support head 12 can be adapted to the use of protective film rolls 4 of different diameters, thereby improving the practicality of the device. By setting the scaling grooves 18, the curved tube of the support head 12 is evenly divided into multiple parts. When installing the protective film roll 4, when the curved tube of the support head 12 is inserted into the interior of the protective film roll 4, the existence of the scaling grooves 18 can reduce the resistance to deformation of the support head 12, thereby facilitating the installation between the protective film roll 4 and the support assembly 2.

[0037] like Figure 2 and Figure 6 As shown, the flattening assembly 3 includes a flattening rod 13 and a flattening roller 14 sleeved thereon, the flattening roller 14 is rotatably connected to the flattening rod 13, the flattening rod 13 includes an outward expansion portion 20 and a transition portion 21, the outward expansion portion 20 and the transition portion 21 are both straight rods, and the outward expansion portion 20 and the transition portion 21 are smoothly connected in a Z shape, the flattening rod 13 is formed by bending a straight rod as a whole, the flattening roller 14 is rotatably sleeved on the outward expansion portion 20, the transition portion 21 is embedded in the second assembly hole 9 and is rotatably connected to the support plate 7, and the flattening roller 1 The inner diameter of the flattening roller 14 is larger than the diameter of the outer expansion portion 20, and the surface of the flattening roller 14 is a smooth surface. By setting the flattening assembly 3, when in use, the deadweight of the flattening assembly 3 will drive the flattening roller 14 to fall downward, and contact with the protective film roll 4 during the falling process. The weight of the flattening rod 13 and the flattening roller 14 can form a flattening pressing force on the side wall of the protective film roll 4, so that the protective film is relatively compact when rolled up, and at the same time reduce the possibility of wrinkles on the unfolded protective film, thereby avoiding wrinkles on the wound protective film roll 4, and effectively improving the rolling quality.

[0038] The working principle provided by the present utility model is as follows. When in use, first, according to the length of the protective film roll 4 to be installed, appropriately adjust the position of the support head 12 on the support screw 10. Then, respectively sleeved the two ends of the protective film roll 4 on the two groups of support heads 12, and sleeve the protective film roll 4 outside the first expansion part 16 or the second expansion part 17 according to the inner diameter of the protective film roll 4 until the protective film roll 4 is clamped with the support head 12. After the installation of the protective film roll 4 is completed, the flattening assembly 3 naturally hangs down, and the flattening roller 14 contacts the side wall of the protective film roll 4 and generates a certain pressure on it. When it is necessary to display the protective film, only need to find the end of the protective film on the protective film roll 4, and then pull it outwards to unfold the protective film. When the protective film is unfolded, it drives the protective film roll 4 to rotate relative to the support plate 7. At the same time, the contact between the protective film and the flattening roller 14 will also drive it to rotate relative to the outward expansion part 20. When unfolding the protective film, the end of the protective film can be passed through the gap between the protective film roll 4 and the flattening roller 14. In this way, the pressure of the flattening roller 14 on the protective film will keep the unfolded protective film in a tensioned state, which is convenient for better display.

[0039] When it is necessary to wind up the unfolded protective film, the support assembly 2 can be driven to rotate integrally by the support screw 11. The protective film roll 4 connected to the support head 12 rotates synchronously with it, and during the rotation process, the unfolded protective film is gradually rewound. And during the rewinding process of the protective film, it drives the flattening roller 14 to rotate. The flattening roller 14 forms a restriction on the protective film, thus avoiding the occurrence of wrinkles. At the same time, the rolling friction between the flattening roller 14 and the protective film causes less wear on the protective film, thereby avoiding damage to the protective film. When it is necessary to move the device, the flattening roller 14 can be directly held, and the device can be lifted integrally through the flattening rod 13, which is convenient for moving.

[0040] The present utility model covers any substitutions, modifications, equivalent methods and solutions made within the essence and scope of the present utility model. In order to enable the public to have a thorough understanding of the present utility model, specific details are described in detail in the following preferred embodiments of the present utility model. However, those skilled in the art can fully understand the present utility model even without these details. In addition, in order to avoid unnecessary confusion to the essence of the present utility model, well-known methods, processes, procedures, components and circuits are not described in detail.

[0041] The above are only the preferred embodiments of the present utility model. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present utility model, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present utility model.
