During the manufacturing process of the central control screen, there is a process design to apply a protective film to the surface of the screen. Automatic or semi-automatic film application machines are usually used to apply the protective film flatly to the screen through a pressure roller assembly. The existing pressure roller assembly is fixedly connected to the cylinder lifting assembly on the film applicator. During use, the surface of the pressure roller is very prone to accumulating dust, fibers, or debris from the release paper behind the film. If not cleaned, these contaminants will be pressed under the film during the next application, causing bubbles and dirt on the screen, resulting in application failure. Currently, the surface of the pressure roller is cleaned manually using cleaning pads and other cleaning products to wipe the surface and manually remove dust particles and other impurities. This is time-consuming, labor-intensive, and inconvenient. The existing pressure roller assembly installed on the laminating machine has the problem of not having a cleaning design that automatically cleans the dust particles and impurities adhering to the surface of the pressure roller.

Detailed Implementation

[0014] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] Please see Figures 1 to 5 This utility model provides a technical solution: a roller assembly for a vehicle central control screen film applicator that is easy to clean, comprising a roller assembly for applying screen film to the surface of the vehicle central control screen, including a horizontal arm 1, a connecting member, and a roller assembly. The connecting member includes a fixing plate 21, a guide rod 22 perpendicular to the fixing plate 21 and passing through the end of the horizontal arm 1, a buffer spring 23 sleeved on the outside of the guide rod 22, and an adjusting cylinder 24. The roller assembly includes a fixed shaft 31 and a film applicator roller 32 rotatably sleeved on the outside of the fixed shaft 31. Figure 1In this context, A represents the display screen of the vehicle's central control screen. Driven by an external displacement cylinder or lead screw, the display screen moves. Under the action of the external cylinder, the roller pressing component moves downward and presses against the surface of the display screen, achieving the purpose of applying the protective film. The principle of using a pressure roller assembly for film application is a conventional existing technology, and this application will not elaborate further on the film application principle and process. The shielding component includes a telescopic rod 4 on the bottom surface of the vertical crossarm 1 and a shielding cover fixedly connected to the bottom end of the telescopic rod 4. 5. A Torx screw runs through the telescopic rod 4. By loosening the Torx screw, the height of the telescopic rod 4 can be manually adjusted, facilitating the change of the height of the shielding cover 5. The shielding cover 5 is installed directly above the film-applying roller 32, serving a certain dust-blocking function to prevent dust particles from settling in the air from adhering to the surface of the film-applying roller 32. The lifting assembly includes a lifting cylinder 6 at the center of the bottom surface of the vertical crossarm 1, a connecting crossarm 7 fixedly connected to the bottom end of the lifting cylinder 6, and a sealing post 71 perpendicularly connected to the bottom surface of the crossarm 7 and passing through the shielding cover 5. Figure 1 The lifting cylinder 6 is in its initial extended state. When the lifting cylinder 6 is in its shortened state, it moves the connecting horizontal plate 7 and the sealing column 71 upward, causing the liquid storage box 8 to change from a blocked state to a flow state, facilitating the flow of the alcohol cleaning solution stored inside the liquid storage box 8 from the bottom of the liquid storage box 8. The cleaning storage assembly for storing alcohol cleaning solution includes the liquid storage box 8, an infusion tube 81 with its top inserted into the liquid storage box 8, a diverter plate 82 fixedly connected to the bottom end of the infusion tube 81, and a cleaning cotton pad 9 sleeved on the outside of the diverter plate 82. The opposite surface of the liquid storage box 8 A fixing post 83 is fixedly connected to the cover 5. When the bottom of the liquid storage box 8 is in a flow state, the alcohol cleaning solution enters the interior of the diversion plate 82 along the infusion tube 81. Then, the alcohol cleaning solution permeates from the surface of the diversion plate 82 to the surface of the cleaning cotton pad 9. As the film-applying roller 32 rotates, the alcohol solution soaked in the cleaning cotton pad 9 adheres to the surface of the film-applying roller 32. The alcohol is volatile, and the volatile alcohol carries away the fine particulate impurities adhering to the surface of the film-applying roller 32. In addition, the cleaning cotton pad 9 also plays the role of physically wiping the surface of the film-applying roller 32, and has the function of cleaning the surface of the film-applying roller 32.

[0016] In this embodiment, the shielding cover 5 is semi-circular in shape, the distance between the shielding cover 5 and the film-applying roller 32 is 5 cm, the adjusting cylinder 24 is fixed with a hand-tightening screw, and there is a gap between the shielding cover 5 and the film-applying roller 32, which does not affect the installation of the cleaning storage component between the shielding cover 5 and the film-applying roller 32.

[0017] In this embodiment, the sealing column 71 slides through the cover 5 and the top surface of the liquid storage box 8. There are five sealing columns 71 and five infusion tubes 81 on the bottom surface of the liquid storage box 8. The infusion tubes 81 are hollow and the sealing columns 71 are solid. The sealing columns 71 and the infusion tubes 81 correspond one-to-one. The bottom surface of the liquid storage box 8 has an outlet for the sealing columns 71 and the infusion tubes 81 to be inserted. When the sealing column 71 is inserted into the outlet, the liquid storage box 8 is in a blocked state to prevent the alcohol cleaning solution for dust removal inside the liquid storage box 8 from evaporating. When the sealing column 71 leaves the outlet, the liquid storage box 8 is in an open state, which facilitates the flow of the alcohol cleaning solution into the interior of the diversion plate 82 under the action of gravity.

[0018] In this embodiment, the liquid storage box 8 has a liquid storage cavity C inside, and the diversion plate 82 has a three-dimensional arc structure. The diversion plate 82 has a diversion cavity D inside, and the liquid storage cavity C and the diversion cavity D are connected by a liquid delivery pipe 81. A seepage port a is opened on the bottom surface of the diversion plate 82. The inner surface of the diversion plate 82 matches the outer surface of the film-applying roller 32. The diversion cavity D is connected to the seepage port a. When the alcohol cleaning liquid flows into the interior of the diversion plate 82 under the action of gravity, the alcohol cleaning liquid can seep out from the seepage port a onto the cleaning cotton pad 9, so that the cleaning cotton pad 9 is in a wet state, which is conducive to wiping and cleaning the surface of the film-applying roller 32.

[0019] In this embodiment, a sliding tube 72 is vertically attached to the end of the connecting horizontal plate 7, and gas supply pipes 10 are fixedly connected to both ends of the liquid storage box 8. Gas ports b are opened on the top surface of both ends of the liquid storage box 8. One end of the gas supply pipe 10 passes through the cover 5 and is inserted into the gas port b. The other end of the gas supply pipe 10 is U-shaped. The top end of the sliding tube 72 slides into the interior of the corresponding end of the gas supply pipe 10. When the lifting cylinder 6 moves the connecting horizontal plate 7 upward, the sliding tube 72 moves upward and squeezes the gas inside the gas supply pipe 10. Under the action of pressure, the alcohol cleaning liquid stored inside the liquid storage box 8 is pressurized, which facilitates the flow of the alcohol cleaning liquid from inside the liquid storage box 8.

[0020] Working principle and usage process of this utility model: Driven by an external displacement cylinder or lead screw, the display screen moves. Under the action of the external cylinder, the roller pressing component moves down and presses against the surface of the display screen, thus achieving the purpose of applying the protective film to the surface of the display screen. The principle of applying film by using the pressure roller assembly is a conventional technical method. Without application, the principle and process of applying film will not be described in further detail. When there is residual dust or impurities on the surface of the film-applying roller 32 that need to be cleaned or cleaned periodically, the manual operation of the control start button will activate the lifting cylinder 6, which is in the initial extension state. When the lifting cylinder 6 is in the shortened state, the lifting cylinder 6 drives the connecting horizontal plate 7 and the sealing column 71 to move upward, so that the liquid storage box 8 changes from the state blocked by the sealing column 71 to the state of flow, which is conducive to the alcohol cleaning liquid stored inside the liquid storage box 8 flowing down from the bottom of the liquid storage box 8. When the sealing column 71 leaves the outlet of the liquid storage box 8, the liquid storage box 8 is in an open state, which facilitates the flow of alcohol cleaning liquid into the interior of the diverter plate 82 under the action of gravity. When the alcohol cleaning solution flows into the interior of the diversion plate 82 under the action of gravity, the alcohol cleaning solution can seep out from the seepage port a onto the cleaning cotton pad 9, making the cleaning cotton pad 9 wet, which is conducive to wiping and cleaning the surface of the film-applying roller 32. As the film-applying roller 32 rotates, the alcohol-soaked cleaning pad 9 adheres to the surface of the film-applying roller 32. The alcohol is volatile, and the volatile alcohol carries away the fine particulate impurities adhering to the surface of the film-applying roller 32. In addition, the cleaning pad 9 also plays the role of physically wiping the surface of the film-applying roller 32, thus having the function of cleaning the surface of the film-applying roller 32. In manual operation, the lifting cylinder 6 is extended, the connecting plate 7 and the sealing column 71 are moved, and the sealing column 71 is embedded in the outlet of the liquid storage box 8, so that the bottom of the liquid storage box 8 is sealed to prevent the alcohol cleaning liquid in the liquid storage box 8 from evaporating. In summary: The roller assembly of the laminating machine in this application has an automatic cleaning design for removing dust particles and impurities adhering to the roller surface. The lifting cylinder 6 drives the sealing column 71 away from the outlet of the liquid storage box 8, and the alcohol cleaning solution flows down and penetrates into the cleaning cotton pad 9. The evaporating alcohol carries away the fine particulate impurities adhering to the surface of the laminating roller 32, and the cleaning cotton pad 9 also physically wipes the surface of the laminating roller 32, thus having a cleaning function.
