The lifting assembly is arranged on the mounting plate, the lifting assembly is drivingly connected with the moving plate, and the first roller lifting assembly and the second roller lifting assembly are symmetrically arranged on the moving plate.

[0004] For the existing device for pressing the edge of a disposable protective clothing film as described above, by setting the first roller lifting assembly and the second roller lifting assembly, the heights of the first roller and the second roller can be adjusted, so that the rolling planes of the first roller and the second roller are the same as the rolling plane of the central roller, or the rolling plane of one of the first roller and the second roller is the same as the rolling plane of the central roller, so that the rolling width can be adjusted according to the width of the film. In the specific process, no matter what width of the film is used, the protective clothing and the film are both abutted against the outside of the baffle. After switching between the first roller and the second roller, the relative position of one side of the roller and one side of the baffle will shift, affecting the subsequent edge pressing effect. Therefore, it is urgent to propose a corresponding device for pressing the edge of a disposable protective clothing film to solve the above problems. Summary of the Utility Model

[0005] The purpose of the utility model is to provide a device for pressing the edge of a disposable protective clothing film to solve the above problems.

[0006] To achieve the above purpose, the utility model adopts the following technical scheme:

[0007] A device for pressing the edge of a disposable protective clothing film includes a bottom plate and multiple groups of pressing wheels. A retaining strip and a bracket are fixedly connected to the top of the bottom plate. A pushing member is fixedly connected to the top of the bracket. A support frame is arranged at the output end of the pushing member. A rotating member is fixedly connected to the outer surface of the vertical end of the support frame. A rotating shaft for axially driving multiple groups of pressing wheels is fixedly connected to the output end of the rotating member. A positioning component for positioning multiple groups of pressing wheels is arranged on the outer surface of the rotating shaft. A support frame for supporting the end of the rotating shaft is detachably connected to the horizontal end of the support frame.

[0008] Preferably, a bottom sleeve and a sliding rod are fixedly connected to the output end of the pushing member and the top of the support frame respectively. The sliding rod is slidably engaged with the bottom sleeve, and a spring and a shock absorber are integrated between the top of the sliding rod and the inner wall of the bottom sleeve.

[0009] Preferably, a tab is fixedly connected to the top of the scaffolding, and the tab is fixedly connected to the horizontal end of the support frame through a fastening rod.

[0010] Preferably, a coupling sleeve is fixedly connected to the outer wall of the scaffolding, and a convex rod is fixedly connected to the end of the rotating shaft. The coupling sleeve is sleeved outside the convex rod.

[0011] Preferably, sliders are fixedly connected to the inner walls of multiple groups of pressing wheels. The sliders are engaged with the inner wall of the rotating shaft through horizontally arranged clamping grooves.

[0012] Preferably, the positioning assembly includes a limiting ring sleeved outside the rotating shaft. A sliding plate slidably engaged with the clamping groove is fixedly connected to the inner wall of the limiting ring. A positioning rod is screwed to the inner wall of the slider, and the open end of the positioning rod abuts against the inner wall of the rotating shaft.

[0013] In summary, due to the adoption of the above technical solutions, the beneficial effects of the present utility model are as follows:

[0014] 1. In this application, the corresponding number of pressing wheels is selected according to the width of the adhesive film. The pressing wheels are arranged on the outside of the rotating shaft in this way. The sliders on the inner walls of the pressing wheels are combined with the clamping grooves, and the sliding plates on the inner wall of the limiting ring are also combined with the clamping grooves. Then, the limiting ring is used to push multiple groups of pressing wheels to be close to each other. Finally, the positioning of the limiting ring and the pressing wheels is realized through the contact friction between the positioning rod and the inner wall of the rotating shaft. The adhesive film and the material edge of the protective clothing are both abutted against the baffle. The pushing member pushes the pressing plate to press the top of the area to be pressed. While the rotating member drives multiple groups of pressing wheels to rotate through the rotating shaft, the operator manually pulls the protective clothing. In this way, the edge pressing of the adhesive film on the protective clothing is realized. While adapting to adhesive films of different widths by increasing or decreasing the number of pressing wheels, the group of pressing wheels closest to the driving member among multiple groups of pressing wheels can always be in alignment with the baffle, thus ensuring the edge pressing effect.

[0015] 2. In this application, the setting of the spring can provide the pressing wheel with vertical telescopic characteristics. If there are hard obstacles on the edge pressing path, the pressing wheel can be telescoped upward to avoid the situation of the pressing wheel being locked or the protective clothing being damaged. The function of the shock absorber is to avoid the continuous shaking during the vertical reset process of the pressing wheel, thereby improving the stability of the use of the edge pressing device for the adhesive film of the disposable protective clothing.

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

[0023] Please refer to Figures 1-4 , the present utility model provides a technical solution:

[0024] A disposable protective clothing film edge pressing device, including a base plate 1 and multiple groups of pressing wheels 8. A stop bar 2 and a bracket 3 are fixedly connected to the top of the base plate 1. A pushing member 4 is fixedly connected to the top of the bracket 3. A support frame 5 is arranged at the output end of the pushing member 4. A rotating member 6 is fixedly connected to the outer surface of the vertical end of the support frame 5. A rotating shaft 19 for axially driving the multiple groups of pressing wheels 8 is fixedly connected to the output end of the rotating member 6. And a positioning component for positioning the multiple groups of pressing wheels 8 is arranged on the outer surface of the rotating shaft 19. A hanging frame 7 for supporting the end of the rotating shaft 19 is detachably connected to the horizontal end of the support frame 5;

[0025] Select the corresponding number of pressing wheels 8 according to the width of the adhesive film. The pressing wheels 8 are arranged in sequence on the outer side of the rotating shaft 19. The sliders 20 on the inner surface of the pressing wheels 8 are combined with the card slots 15. The sliding plates 17 on the inner surface of the limiting rings 16 are also combined with the card slots 15. Then, the limiting rings 16 are used to push multiple groups of pressing wheels 8 to be closely attached. Finally, the positioning of the limiting rings 16 and the pressing wheels 8 is realized through the contact friction between the positioning rods 18 and the inner surface of the rotating shaft 19. Press the adhesive film and the edge of the protective clothing against the stop strip 2. The pushing member 4 pushes the pressing wheels 8 to press the top of the area to be pressed. While the rotating member 6 drives multiple groups of pressing wheels 8 to rotate through the rotating shaft 19, manually pull the protective clothing. In this way, the edge pressing of the adhesive film on the protective clothing is realized. While adapting different widths of adhesive films by increasing or decreasing the number of pressing wheels 8, there is always a group of pressing wheels 8 at the limit position of the card slot 15, and this group of pressing wheels 8 is exactly in alignment with the stop strip 2, thus ensuring the edge pressing effect of the adhesive film on the protective clothing.

[0026] Specifically, as Figure 2 shown in Figure 4 , the output end of the pushing member 4 and the top of the support frame 5 are respectively fixedly connected with a bottom sleeve 9 and a sliding rod 10. The sliding rod 10 is slidably matched with the bottom sleeve 9. A spring 11 and a shock absorber 12 are integrated between the top of the sliding rod 10 and the inner surface of the bottom sleeve 9. The spring 11 can provide the vertical telescopic characteristic for the pressing wheel 8. If there are hard obstacles on the edge pressing path, the pressing wheel 8 can be telescoped upward to avoid the situation of the pressing wheel 8 being locked or the protective clothing being damaged. The function of the shock absorber 12 is to avoid the continuous shaking during the vertical reset of the pressing wheel 8, thereby improving the stability of the use of the edge pressing device for the adhesive film of the disposable protective clothing.

[0027] Specifically, as Figure 2 shown in Figure 3 , a tab is fixedly connected to the top of the support frame 7. The tab is fixedly connected to the horizontal end of the support frame 5 through a fastening rod, ensuring the convenience of disassembly and assembly of the support frame 7. A coupling sleeve 13 is fixedly connected to the outer surface of the support frame 7. A convex rod 14 is fixedly connected to the end of the rotating shaft 19. The coupling sleeve 13 is sleeved on the outer side of the convex rod 14, realizing the support of the end of the rotating shaft 19 and ensuring the convenience of separation between the support frame 7 and the rotating shaft 19. Sliders 20 are fixedly connected to the inner surfaces of multiple groups of pressing wheels 8. The sliders 20 are engaged with the inner surface of the rotating shaft 19 through horizontally arranged card slots 15, thereby realizing the axial linkage between the rotating shaft 19 and multiple groups of pressing wheels 8. The positioning assembly includes a limiting ring 16 sleeved on the outer side of the rotating shaft 19. A sliding plate 17 that is slidably matched with the card slot 15 is fixedly connected to the inner surface of the limiting ring 16. A positioning rod 18 is screwed to the inner surface of the slider 20, and the open end of the positioning rod 18 abuts against the inner surface of the rotating shaft 19. Multiple groups of pressing wheels 8 are pushed to be closely attached through the limiting ring 16, and finally the positioning of the limiting ring 16 and the pressing wheels 8 is realized through the contact friction between the positioning rod 18 and the inner surface of the rotating shaft 19.

[0028] Working principle: Select the corresponding number of pressure wheels 8 according to the width of the adhesive film. The pressure wheels 8 are arranged in sequence on the outer side of the rotating shaft 19. The slider 20 on the inner surface of the pressure wheel 8 is combined with the clamping groove 15, and the sliding plate 17 on the inner surface of the limiting ring 16 is also combined with the clamping groove 15. Then, the limiting ring 16 is used to push multiple pressure wheels 8 to be closely attached. Finally, the positioning of the limiting ring 16 and the pressure wheel 8 is achieved through the contact friction between the positioning rod 18 and the inner surface of the rotating shaft 19. The adhesive film and the material edge of the protective clothing are both abutted against the retaining strip 2. The pushing member 4 pushes the pressure wheel 8 to press the top of the area to be pressed. While the rotating member 6 drives multiple pressure wheels 8 to rotate through the rotating shaft 19, the protective clothing is manually pulled, so as to realize the edge pressing of the adhesive film on the protective clothing. By increasing or decreasing the number of pressure wheels 8 to adapt to adhesive films of different widths, there is always a group of pressure wheels 8 at the limit position of the clamping groove 15, and this group of pressure wheels 8 is exactly in alignment with the retaining strip 2, thus ensuring the edge pressing effect of the adhesive film on the protective clothing. The setting of the spring 11 can provide the vertical telescopic characteristic for the pressure wheel 8. If there are hard obstacles on the edge pressing path, the pressure wheel 8 can be telescoped upward to avoid the situation of the pressure wheel 8 being locked or the protective clothing being damaged. The function of the shock absorber 12 is to avoid the continuous jitter during the vertical resetting of the pressure wheel 8, thereby improving the stability of the use of the edge pressing device for the adhesive film of the disposable protective clothing.
