Technical Field
[0001] The utility model relates to the technical field of back coating devices, in particular to a back coating device for laser direct aluminum plating paper. Background Art
[0002] Laser-coated aluminum foil is a new technology that has seen rapid growth and application both domestically and internationally in recent years. It is gradually replacing aluminum foil composite paper as the base material for aluminum foil. This type of laser-coated aluminum foil is primarily used in packaging for tobacco, alcohol, food, gifts, cosmetics, and labels, offering a distinctive texture and color. Compared to aluminum foil composite paper, direct-coated aluminum foil reduces the thickness of the aluminum coating, lowering material costs, making it easier to recycle and decompose in soil, contributing to environmental benefits. To improve the quality of laser-coated aluminum foil, a layer of material must be applied to the back of the base paper to conceal any imperfections. This is accomplished using a back coating device.
[0003] When the existing back coating device is in use, the back coated base paper is usually left to dry naturally. This drying process takes a long time, which is not conducive to the subsequent processing flow of the base paper and affects the production efficiency of laser direct aluminum plating paper. Therefore, it is necessary to design a back coating device for laser direct aluminum plating paper. Utility Model Content

[0025] Reference Figure 1-4 The utility model provides a back coating device for laser direct aluminum plating paper, including a base plate 1, a first support frame 2 and a holding tank 5 are fixedly connected to the upper end of the base plate 1, the holding tank 5 is located inside the first support frame 2, an adjusting mechanism 4 is provided at the upper end of the first support frame 2, a pressing roller 10 is provided inside the first support frame 2, and the adjusting mechanism 4 is used to adjust the position of the pressing roller 10; a back coating roller 6 is rotatably connected to the lower end of the first support frame 2, a second motor 11 is fixedly connected to the side end of the first support frame 2, the output end of the second motor 11 is fixedly connected to the back coating roller 6, and the lower end of the back coating roller 6 is located inside the holding tank 5; a scraping mechanism 3 is provided inside the rear end of the first support frame 2; and an air-drying mechanism 8 is provided on the rear side of the upper end of the base plate 1.
[0026] Specifically, the back coating liquid is added to the inside of the holding tank 5, and then the base paper is passed between the back coating roller 6 and the pressure roller 10, and then passed through the upper end of the scraper mechanism 3, and then passed through the upper end of the air-drying mechanism 8. After the base paper is laid, the adjustment mechanism 4 is used to drive the pressure roller 10 to move toward the back coating roller 6, so as to facilitate the contact between the base paper and the back coating roller 6. After the base paper contacts the back coating roller 6, the second motor 11 is operated to drive the back coating roller 6 to rotate. As the back coating roller 6 rotates, the back coating liquid adhered to the surface of the back coating roller 6 will be coated on the surface of the base paper, thereby achieving the purpose of back coating. Then, when the back-coated base paper passes through the scraper mechanism 3, the excess back coating liquid on the surface of the base paper can be cleaned up under the action of the scraper mechanism 3, thereby reducing the waste of back coating liquid; when the back-coated base paper passes through the upper end of the air-drying mechanism 8, the back-coated base paper can be air-dried under the action of the air-drying mechanism 8, so that the air-drying speed of the base paper can be accelerated, which is beneficial for the base paper to perform the next step operation, thereby improving the production efficiency of laser direct aluminum plating paper.
[0027] The adjusting mechanism 4 includes an electric telescopic rod 401, a guide rod 402 and a moving frame 403. The upper end of the first support frame 2 is fixedly connected to the electric telescopic rod 401, and the extended end of the electric telescopic rod 401 passes through the first support frame 2 and is slidably connected to the first support frame 2. The extended end of the electric telescopic rod 401 is fixedly connected to the moving frame 403, and the moving frame 403 is rotatably connected to the pressure roller 10. The upper end of the moving frame 403 is fixedly connected to the guide rod 402, and the guide rod 402 is slidably connected to the first support frame 2. When working, the electric telescopic rod 401 works to drive the moving frame 403 to move, and then drives the guide rod 402 to move. Under the action of the guide rod 402, the movement of the moving frame 403 can be made more stable. As the moving frame 403 moves, the pressure roller 10 can be driven to move. When the pressure roller 10 moves toward the back coating roller 6, it is convenient for the base paper to contact the back coating roller 6, thereby facilitating the back coating operation on the base paper.

When working, by setting the first motor 301 and the scraping roller 302, the first motor 301 works, and then the scraping roller 302 can be driven to rotate. As the scraping roller 302 rotates, when the back-coated base paper passes through the scraping roller 302, the scraping roller 302 can scrape off excess back-coating liquid, thereby reducing the waste of back-coating liquid.
[0029] A guide groove 9 is fixedly connected to the inside of the first support frame 2, and the guide groove 9 is located at the lower end of the scraper roller 302. When working, the guide groove 9 is set to facilitate the scraped back coating liquid to flow back to the inside of the holding tank 5 under the action of the guide groove 9.
[0030] A guide roller 7 is rotatably connected to the front end of the first support frame 2 , and the guide roller 7 corresponds to the scraper roller 302 . When working, the guide roller 7 is provided to facilitate the movement of the base paper under the action of the guide roller 7 .
