[0002] With the development of protective film technology, plastic protective film is a special functional film widely used in various industries and fields. Its main function is to protect the surface of products from damage or contamination. In the production and processing process, it is often necessary to apply adhesive to its surface through an adhesive coating device to make the plastic protective film perform even better.

[0003] Existing plastic protective film coating devices often require coating one side of the plastic protective film before applying the other side, resulting in wasted time. Utility Model Content

[0004] The purpose of this invention is to solve the problem that existing plastic protective film coating devices often require coating one side of the plastic protective film first, and then coating the other side, which wastes time. Therefore, this invention proposes a plastic protective film coating device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A plastic protective film coating device, comprising:

[0007] The main body contains an adhesive roller and a steel roller. Both the steel roller and the adhesive roller are connected to the inner top of the main body via a connecting frame. A connecting rod is connected to the middle of the inner top of the main body. A sleeve is installed below the connecting rod, and a groove is formed on the outer wall of the sleeve. A slider is slidably arranged on the inner side of the groove and is connected to the bottom end of the connecting rod. A toothed ring is fitted on the middle of the outer wall of the sleeve, and a gear is meshed at the bottom of the toothed ring. A rotating shaft is installed at one end of the gear, and a servo motor is connected to the other end of the rotating shaft. A bearing plate is horizontally installed on the middle of the inner side of the main body, and a rotating plate assembly is connected to the middle of the bearing plate. The middle of the rotating plate assembly is connected to the inner wall of the sleeve, and a limit frame is connected to the top of the rotating plate assembly.

[0008] Preferably, the top two sides of the main body have glue inlets.

[0009] Preferably, the glue-applying rollers are symmetrically distributed about the central axis of the main body.

[0010] Preferably, the sleeve forms a transmission structure with a gear and a toothed ring.

[0011] Preferably, the upper surface of the rotating plate assembly is flush with the upper surface of the bearing plate.

[0012] Preferably, the slider is arranged in an arc shape, and the slider is connected to the connecting rod by bolts to form a detachable structure.

[0013] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0014] 1. In this utility model, by setting up the sleeve, rotating plate assembly, main body, etc., when it is necessary to perform double-sided adhesive application on the plastic protective film, the servo motor can be started, which drives the rotating shaft to rotate, thereby driving the gear to rotate, which in turn drives the meshing gear ring to rotate, which in turn drives the sleeve to rotate, making it easier for the rotating plate assembly inside to rotate, thereby completing the flipping operation of the plastic protective film. This allows the adhesive roller on one side of the main body to apply adhesive to one side of the plastic protective film, and the adhesive roller on the other side of the main body to apply adhesive to the other side of the plastic protective film, which can effectively save time.

[0020] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0021] Reference Figure 1-3A plastic protective film coating device includes a main body 1, inside which a coating roller 2 and a steel roller 3 are installed. Glue inlets 5 penetrate both sides of the top of the main body 1, allowing glue to be injected and flow to the intersection of the steel roller 3 and the coating roller 2 for subsequent coating. The coating rollers 2 are symmetrically distributed about the central axis of the main body 1, allowing one side of the coating roller 2 to coat one side of the plastic protective film, while the other side can coat the flipped side of the plastic protective film. In the glue application process, both the steel roller 3 and the glue application roller 2 are connected to the inner top of the main body 1 via the connecting frame 4. A connecting rod 8 is connected to the middle of the inner top of the main body 1. A sleeve 7 is placed below the connecting rod 8, and a groove 16 is provided on the outer wall of the sleeve 7. A slider 15 is slidably arranged inside the groove 16, and the slider 15 is connected to the bottom end of the connecting rod 8. The slider 15 has an arc-shaped structure, and the slider 15 is detachable from the connecting rod 8 by bolts, so that the arc-shaped slider 15 can fit more closely to the groove 16 for sliding operation.

[0022] A toothed ring 9 is fitted onto the middle of the outer wall of the sleeve 7, and a gear 10 is meshed with the bottom of the toothed ring 9. A rotating shaft 11 is mounted on one end of the gear 10, and a servo motor 12 is connected to the other end of the rotating shaft 11. A bearing plate 6 is horizontally mounted on the middle of the inner side of the main body 1, and a rotating plate assembly 13 is connected to the middle of the bearing plate 6. The sleeve 7 forms a transmission structure with the gear 10 through the toothed ring 9. When the plastic protective film needs to be flipped, the servo motor 12 is started, which drives the rotating shaft 11, causing the rotating shaft 11 to drive the gear 10 to rotate. It engages with the gear ring 9 to drive the sleeve 7 to rotate, thus driving the rotating plate assembly 13. Therefore, the plastic protective film on the rotating plate assembly 13 can be flipped. The middle part of the rotating plate assembly 13 is connected to the inner wall of the sleeve 7, and the top of the rotating plate assembly 13 is connected to the limit frame 14. The upper surface of the rotating plate assembly 13 is flush with the upper surface of the bearing plate 6, so that the plastic protective film can pass smoothly through the rotating plate assembly 13 and the rotating plate assembly 13 can support the plastic protective film.

[0023] Working principle: In use, the operator first starts the device and adds glue through the glue inlet 5, allowing the glue to flow to the intersection of the coating roller 2 and the steel roller 3. As the coating roller 2 and the steel roller 3 rotate, they can apply glue to the pre-placed plastic protective film. Subsequently, when double-sided glue application is required, the servo motor 12 is started, which drives the rotating shaft 11 to rotate, thereby driving the gear 10 to rotate, which in turn drives the meshing gear ring 9 to rotate, which in turn drives the sleeve 7 to rotate, facilitating the rotation of the internally placed rotating plate assembly 13. This completes the flipping operation of the plastic protective film restricted by the limiting frame 14, so that the coating roller 2 on one side of the main body 1 applies glue to one side of the plastic protective film, and the coating roller 2 on the other side of the main body 1 applies glue to the other side of the plastic protective film, finally completing the glue application work of the plastic protective film.

[0024] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
