Detailed Implementation

[0018] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0019] Example

[0020] like Figures 1-8As shown, this embodiment includes a substrate 1 and a pressing assembly and a paper-breaking pressure roller assembly disposed on the substrate 1. A recessed platform 2 is formed inward on the upper surface of the substrate 1, which is used to place signs and apply films. Sliding strips 3 are symmetrically arranged on both sides of the substrate 1.

[0021] like Figures 1-3 As shown, a clamping assembly is disposed at one end of the substrate 1, used to clamp the sign and sticker placed in the recessed platform 2 from that end. The clamping assembly includes a set of second locking hook plates 4 rotatably connected to both sides of the substrate 1 via bearings at their lower parts, a pressure block 5 disposed above the recessed platform 2, a pressing plate 6 connected to both ends of the pressure block 5, and a set of third tension springs 7 connected at one end to both sides of the substrate 1, with the other end of the third tension spring 7 connected to the middle of the second locking hook plate 4. A second hook portion 8 is provided on the upper part of the second locking hook plate 4. One end of the pressing plate 6 is rotatably connected to both sides of the substrate 1 via bearings. The pressure block 5 can rotate about the bearing connection between the pressing plate 6 and the substrate 1 to change its distance relative to the recessed platform 2, thereby clamping the sign and sticker in the recessed platform 2. A second locking hook shaft 9 is provided in the middle of the pressing plate 6, which can cooperate with the second hook portion 8. The second hook portion 8 hooks onto the second locking hook shaft 9, and the third tension spring 7 is used to clamp the pressure block 5 onto the sign and sticker.

[0022] like Figures 1-2 , Figure 4As shown, the paper-cutting pressure roller assembly is located next to the pressing assembly and is used to cut the film covering and simultaneously attach the film to the sign. The paper-cutting pressure roller assembly includes a set of connecting sliders 10 mounted on the slider 3 and movable along the slider 3, a pull rod shaft 11 disposed between the connecting sliders 10 and located above the sink 2, a first locking hook plate 12 rotatably connected to both ends of the pull rod shaft 11, a set of first tension springs 13 connected at one end to the connecting sliders 10, and a set of pressure roller connecting plates 14 rotatably connected to both sides of the connecting sliders 10 via bearings at their lower parts. The other end of the first tension spring 13 is connected to the middle of the first locking hook plate 12. A pressure roller 15 is provided between the upper parts of the pressure roller connecting plates 14. Specifically, the pressure roller 15 can be lifted by the pressure roller connecting plates 14 to facilitate the placement of the sign and film in the sink 2. After the pressure roller connecting plates 14 are released, the pressure roller 15 will return to its original position under the action of the first tension spring 13 until it is pressed onto the sign. A first hook portion 16 is provided on the upper part of the first locking hook plate 12, and a first locking hook shaft 17 that can cooperate with the first hook portion 16 is provided in the middle of the pressure roller connecting plate 14. Specifically, by hooking the first locking hook shaft 17 with the first hook portion 16, the pressure roller 15 can be raised. A cutting aluminum groove 18 is provided above the pressure roller 15. The two ends of the cutting aluminum groove 18 are fixedly connected to the pressure roller connecting plate 14. A cutting knife 19 that can move along the cutting aluminum groove 18 is provided in the cutting aluminum groove 18, and the bottom of the cutting knife 19 is located directly above the pressure roller 15. There is a certain gap between the cutting aluminum groove 18 and the pressure roller 15. This gap allows the film to be pasted on the sign to pass through. In this state, the film-covered side of the film is facing upward. The film can be cut by moving the cutting knife 19 along the cutting aluminum groove 18.

[0023] In this embodiment, a second tension spring 20 is also connected between the connecting slider 10 and the pressure roller connecting plate 14. One end of the second tension spring 20 is connected to the connecting slider 10, and the other end of the second tension spring 20 is connected to the middle of the pressure roller connecting plate 14. The second tension spring 20 is provided to provide the pressure roller connecting plate 14 with the function of resetting.

[0024] like Figures 1-4 As shown, the upper part of the connecting slider 10 is provided with a groove 21, and the upper part of the first locking hook plate 12 is connected with a block 22 facing the connecting slider 10. The block 22 can abut against the groove 21 to prevent the first locking hook plate 12 from moving too fast under the action of external force.

[0025] The working process of this auxiliary film-applying device is as follows: The second hook 8 is disengaged from the pressure plate 6, causing the pressure block 5 to rise. The pressure roller 15 is then raised until the first hook 16 hooks the first locking hook shaft 17. Subsequently, the sign is placed into the sinking platform 2. Figures 5-6 As shown; align the front end of the film with the sign, press down the pressure block 5, and hook the second hook 8 onto the second locking hook shaft 9. Then, flip the middle and rear part of the film and pass it through the gap between the aluminum groove 18 and the pressure roller 15. Use the engraving knife 19 to cut open the back film, and lift up the front end of the rear half of the film, as shown. Figure 7 As shown; the first hook 16 is disengaged from the first locking hook shaft 17, the pressure roller 15 is reset, and then the pull rod shaft 11 is pulled to apply a reverse pulling force. As the paper breaking pressure roller assembly moves along the slide bar 3, the pressure roller 15 presses the film onto the sign.
