Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of advertising film production, in particular to a coating device for weather-resistant reflective advertising film. Background Art
[0002] Reflective advertising film, an innovative advertising material, demonstrates exceptional visual appeal at night or in low-light environments with its unique reflective properties. It is widely used in road signs, traffic safety devices, commercial billboards, and building exterior decoration. Using microprisms or glass microbead technology, this material reflects incident light back at a specific angle toward the source, significantly enhancing visual recognition and safety. Its weather-resistant design ensures that it maintains its excellent physical properties and reflective effect in varying climates, including high and low temperatures, humidity, and UV radiation, extending its service life.
[0003] The coating system plays a crucial role in the production and processing of reflective advertising film. Currently, the most common coating equipment on the market utilizes a laminating machine in conjunction with a glue tank. Specifically, the reflective advertising film is first fed into the laminating machine, then passes through a tank of liquid glue, where a specialized device evenly coats the top surface of the film. After gluing, the film enters a drying area, where hot air or natural air drying removes moisture from the glue, achieving an optimal adhesive state for subsequent attachment to various surfaces. This coating method significantly improves the efficiency and convenience of reflective advertising film installation.
[0004] However, the current reflective advertising film coating process still has some significant drawbacks in practical applications. First, the liquid glue is directly exposed to the air during the coating process, which not only increases the risk of glue contamination, but also allows dust and impurities to easily fall into the glue and adhere to the surface of the reflective advertising film, seriously affecting its subsequent adhesion and aesthetics. Second, after coating, the remaining glue in the glue pool often lacks an effective recovery mechanism, resulting in the residual glue being directly discharged to the ground, not only wasting resources but also requiring staff to clean up. Utility Model Content
[0005] In order to overcome the shortcomings of glue being easily contaminated and excess glue being unable to be recycled, the utility model provides a coating device for a weather-resistant reflective advertising film which is anti-fouling and has a recycling function.
[0006] A coating device for weather-resistant reflective advertising film includes a coating body and an advertising film. The coated advertising film is wound on the coating body.

DETAILED DESCRIPTION
[0020] The present invention will be described in further detail below with reference to the accompanying drawings and specific embodiments, but this does not limit the scope of protection and application of the present invention.
[0021] Example: A coating device for a weather-resistant reflective advertising film, such as Figure 1-Figure 5 As shown, it includes a coating body 1 and an advertising film 101. The coated advertising film 101 is wound on the coating body 1. The coating body 1 is provided with a guide roller for guiding the movement of the advertising film 101. It also includes a loading assembly, a discharge plate 7, a mounting plate 9 and a recycling assembly. The coating body 1 is provided with a loading assembly for conveying glue. The loading assembly is connected to the discharge plate 7. A plurality of guide holes 8 are opened in the discharge plate 7. The lower end of the discharge plate 7 is connected to the mounting plate 9. The coating body 1 is provided with a recycling assembly. The recycling assembly is connected to the loading assembly and the discharge plate 7 for recycling excess glue.
[0022] like Figure 1 and Figure 2 As shown, the loading assembly includes a raw material barrel 2, a feed cover 3, a feed pipe 4, a water pump 5 and a storage box 6. The raw material barrel 2 is fixed to the side of the coating body 1, and the storage box 6 is fixed to the top of the coating body 1. The raw material barrel 2 is connected to the feed cover 3. One end of the feed pipe 4 is connected to the top of the storage box 6, and the other end passes through the raw material barrel 2 and is installed with a water pump 5. The water pump 5 is located in the raw material barrel 2. The excess glue is collected by the recovery assembly and returned to the raw material barrel 2 to realize the recycling of the glue.
[0023] like Figure 3-Figure 5As shown, the recovery component includes a scraper 10, a recovery pipe 11 and a recovery trough 1101. The scraper 10 is connected to the bottom of the discharge plate 7, the recovery pipe 11 is connected to one side of the coating body 1, the advertising film 101 passes through the top opening of the recovery pipe 11, and the bottom opening of the recovery pipe 11 is connected to the raw material barrel 2. The recovery trough 1101 is connected to the coating body 1 and is located at the bottom of the scraper 10. One end of the recovery trough 1101 is connected to the recovery pipe 11. The side of the scraper 10 close to the recovery pipe 11 is thinner, and the side away from the recovery pipe 11 is thicker. This design makes it easier to push excess glue toward the recovery pipe 11, so that when the excess glue passes through the scraper 10, it will be squeezed and pushed toward the recovery pipe 11. The depth of the groove in the recovery trough 1101 is shallower on the side away from the recovery pipe 11 and deeper on the side close to the recovery pipe 11, so that the remaining glue will flow to the recovery pipe 11 along the inclined surface of the recovery trough 1101.
[0024] The staff puts the advertising film 101 that needs to be coated with glue in the coating machine body 1, and the other end of the advertising film 101 passes through the drying equipment and is connected to the winding equipment. At the same time, the water pump 5 is turned on to pump the glue in the raw material barrel 2 into the storage box 6 through the feeding pipe 4. The glue in the storage box 6 flows out along the guide hole 8 opened in the discharge plate 7 and falls on the moving advertising film 101. The glue will remain directly on the advertising film 101. The advertising film 101 continues to move. When passing through the scraper 10, the excess glue on the advertising film 101 is scraped off, so that the glue height on the advertising film 101 is at a suitable thickness. At the same time, it can flatten the uneven glue and scrape the excess glue to the left. The glue flows along the scraper 10 into the recovery pipe 11 and flows into the raw material barrel 2 along the recovery pipe 11. Figure 2 , a filter is provided at the bottom of the recovery pipe 11, which can filter the refluxed glue to ensure the cleanliness of the glue after contact with the air. As the coating work proceeds, the staff observes the consumption rate of the glue and adjusts the extraction rate of the water pump 5 to make the rate at which the water pump 5 extracts glue slightly greater than the consumption rate of the glue, and when the excess glue is scraped off, it will not overflow when passing through the recovery pipe 11, maintaining a balanced state. When a roll of advertising film 101 is about to be coated, the water pump 5 is turned off, and the remaining glue in the storage box 6 falls into the recovery tank 1101 after the coating is completed, and flows into the recovery pipe 11 along the recovery tank 1101, and finally flows back to the raw material barrel 2, reducing the waste of glue;
[0025] like Figure 1 As shown, a transparent scale plate 15 is also included. Transparent scale plates 15 are set on both sides of the storage box 6 to display the amount of glue in the storage box 6.
[0026] When adjusting the extraction rate of the water pump 5, the staff first observes the changes in the amount of glue in the storage box 6 through the transparent scale plate 15, then observes the amount of glue blocked by the scraper 10, and ensures the height of the glue in the storage box 6, and finally slowly adjusts the extraction rate of the water pump 5. When a roll of advertising film 101 is about to be coated, the staff can accurately observe the remaining amount of glue in the storage box 6 through the transparent scale plate 15, so as to accurately judge when to turn off the water pump 5.
[0027] like Figure 1 As shown, a protective net 14 is also included. A through hole is opened on the top of the storage box 6, and a protective net 14 is set on the through hole. The through hole can discharge the air in the storage box 6 and maintain the atmospheric pressure in the storage box 6, thereby ensuring that the glue can flow out smoothly when passing through the material guide hole 8.
[0028] The protective net 14 can prevent foreign objects from entering the storage box 6, and can also ensure air circulation, maintain the atmospheric pressure in the storage box 6, and allow the glue to flow out smoothly.
[0029] like Figure 1 As shown, it also includes a handle 13 and a bracket 12. The handle 13 is connected to the feed cover 3, and the bracket 12 is connected to the side of the raw material barrel 2 for placing the feed cover 3.
[0030] It is more convenient to open the feed cover 3 through the handle 13, and when adding materials to the raw material barrel 2, the feed cover 3 can be placed on the bracket 12, and the bracket 12 is close to the feeding port of the raw material barrel 2, which is convenient for placing the feed cover 3.
[0031] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any modifications or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be based on the scope of protection of the claims.
