Technical Field
[0001] This utility model relates to the field of coating device technology, and in particular to a coating device for anti-counterfeiting packaging paper. Background Technology
[0002] Coating equipment is mainly used to coat the surface of substrates such as films and paper. The coating equipment coats a roll of substrate with a layer of adhesive, paint or ink with a specific function, and after drying, it is rolled up to complete the coating operation. After the anti-counterfeiting packaging paper is produced, the packaging paper is coated by the coating equipment to coat the packaging paper with a functional protective film.
[0003] A search revealed Chinese Patent Publication (Announcement) No. CN215695434U, which discloses an anti-counterfeiting packaging paper coating device. The device includes a coating housing with an installation groove on its outer side and two coating tubes connected to a material container. Each coating tube has a coating section. A spacer is connected to the inner wall of the coating housing to drive the two coating tubes to coat the packaging paper at intervals, forming two right-angled anti-counterfeiting coatings on the packaging paper. An end-edge stabilizing component is connected to the bottom of the coating housing to stabilize the ends of the packaging paper. The output end of the end-edge stabilizing component is connected to a transmission component. When coating the packaging paper with anti-counterfeiting paint, the packaging paper to be treated is placed inside the coating housing.

Detailed Implementation
[0024] 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. Example
[0025] like Figure 1-5 As shown, an anti-counterfeiting packaging paper coating device includes a housing 1. A first coating box 2 is fixedly connected to the middle of the bottom wall of the housing 1. A first coating roller 3 is rotatably connected to the top of the inner side of the first coating box 2. A first pressure roller 4 is rotatably connected to the inner side of the housing 1 near the top of the first coating roller 3. A guide roller 5 is rotatably connected to one side of the inner side of the housing 1. A second coating box 6 is fixedly connected to the middle of the inner side of the housing 1. A second coating roller 7 is rotatably connected to the top of the inner side of the second coating box 6. A second pressure roller 8 is rotatably connected to the inner side of the housing 1 near the top of the second coating roller 7. A discharge roller 9 is rotatably connected to the inner side of the housing 1 near the side of the guide roller 5.
[0026] In practical use, through the arrangement of the first coating roller 3, the first pressure roller 4, the guide roller 5, the second coating roller 7, and the second pressure roller 8, the first paint box 2 and the second paint box 6 are respectively located in the middle of the bottom wall and the middle of the inner side of the housing 1. These boxes store paint and support the first coating roller 3 and the second coating roller 7, while also collecting the paint scraped off by the comma roller 17, preventing paint waste and reducing coating costs. The packaging paper passes between the first coating roller 3 and the first pressure roller 4. While the first coating roller 3 rotates and conveys the packaging paper, it applies the paint from the first paint box 2 to the lower surface of the packaging paper. The guide roller 5 then conveys the coated packaging paper to the second coating roller 7 and the second pressure roller 8. Between rollers 8, the packaging paper is flipped over simultaneously, and the second coating roller 7 applies the coating from the second coating box 6 to the other side of the packaging paper, enabling the device to coat both sides of the packaging paper at the same time, simplifying the process and making the operation simple and quick. The first coating roller 3 and the second coating roller 7 are made of rubber material. Because rubber is elastic and soft, it can evenly coat the coating paper on the surface, reduce the coating error rate, and have higher coating accuracy and uniformity. The first pressure roller 4 and the second pressure roller 8 can make the packaging paper better contact with the first coating roller 3 and the second coating roller 7, ensuring the coating quality. The discharge roller 9 discharges the coated packaging paper to avoid scratching the shell 1 and causing scratches on the coating surface.
[0027] In this embodiment, a material level sensor 10 is fixedly connected to the top of the inner side of the first paint box 2 and the second paint box 6, and a feeding pipe 11 is fixedly connected to the top of the outer surface of the first paint box 2 and the second paint box 6.
[0028] In practical use, the material level sensor 10 is set, and the feeding pipe 11 is connected to the pipeline of the mixed paint tank. The material level sensor 10 detects the amount of paint inside the first paint box 2 and the second paint box 6. When the amount of paint reaches the set value, the material level sensor 10 automatically replenishes the paint through the feeding pipe 11.
[0029] In this embodiment, a fixing block 12 is fixedly connected to the bottom and top of the inner side of the housing 1. A support plate 13 is rotatably connected to the inner side of the fixing block 12. A fixing rod 14 is fixedly connected to the middle of the inner side of the support plate 13. A hydraulic rod 15 is rotatably connected to the middle of the outer surface of the fixing rod 14. The hydraulic rod 15 is rotatably connected to the housing 1.
[0030] In practical use, the hydraulic rod 15 is used to rotatably connect one end of the support plate 13 to the inner side of the fixed block 12, and the other end supports the motor 16 and the comma roller 17. The two ends of the hydraulic rod 15 are rotatably connected to the housing 1 and the fixed rod 14, respectively. When the output end of the hydraulic rod 15 extends or retracts, the fixed rod 14 drives the support plate 13 to rotate a certain angle around the center of the connection between the fixed block 12 and the support plate 13, thereby adjusting the position of the comma roller 17 according to the different coating thicknesses and expanding the range of applications.
[0031] In this embodiment, a motor 16 is fixedly connected to one side of the outer surface of the support plate 13, and a comma roller 17 is fixedly connected to the output end of the motor 16.
[0032] In practical use, the comma roller 17 is a commonly used paint scraper roller structure. The motor 16 drives the comma roller 17 to rotate, scraping off excess paint from the surface of the packaging paper. This makes operation convenient and reduces coating costs.
[0033] In this embodiment, connecting plates 18 are fixedly connected to both sides of the bottom of the outer surface of the housing 1, and cleaning rollers 19 are rotatably connected to both sides of the inner side of the connecting plates 18.
[0034] In practical use, the cleaning roller 19 is set up and the connecting plate 18 supports one end of the cleaning roller 19. The cleaning roller 19 has a hollow structure inside and a threaded groove on its surface. This allows the two sets of cleaning rollers 19 to guide the packaging paper into the device while cleaning the dust and impurities on both sides of the packaging paper, ensuring uniformity during subsequent coating and guaranteeing coating quality.
[0035] In this embodiment, a fixed tube 20 is rotatably connected inside the cleaning roller 19. A connecting tube 21 is fixedly connected to one end of the fixed tube 20, and a vacuum cleaner 22 is fixedly connected to one end of the connecting tube 21. The vacuum cleaner 22 is fixedly connected to the housing 1.
[0036] In practical use, the vacuum cleaner 22 is connected to the fixed tube 20 via the connecting tube 21. The two sets of fixed tubes 20 support the cleaning roller 19, and multiple through holes are opened on its surface, so that the cleaning roller 19 can generate suction. The fixed tube 20 and the vacuum cleaner 22 collect the dust and impurities cleaned from the surface of the packaging paper, preventing the dust from being scattered randomly.
[0037] In this embodiment, a heater 23 is fixedly connected to the center of the front side of the housing 1, a first conveying pipe 24 is fixedly connected to one side of the outer surface of the heater 23, and a first drying hood 25 is fixedly connected to one end of the first conveying pipe 24.
[0038] In practical use, the heater 23 generates heat when it is in operation, and the heat is transported to the inside of the first drying hood 25 through the first conveying pipe 24. The first drying hood 25 dries the coating on the surface of the packaging paper coated by the first coating roller 3, so that the coating dries quickly, avoids contamination of the surface of the guide roller 5, and improves coating efficiency.
[0039] In this embodiment, a second conveying pipe 26 is fixedly connected to the upper surface of the heater 23, and a second drying hood 27 is fixedly connected to one end of the second conveying pipe 26.
[0040] In practical use, the second drying hood 27 is set up so that the heat inside the heater 23 is transported to the inside of the second drying hood 27 by the second conveying pipe 26. The second drying hood 27 is fixed to the inner top wall of the housing 1 and heats and dries the surface of the packaging paper coated by the second coating roller 7, thereby accelerating the curing effect of the coating.
[0041] Working principle: In use, the vacuum cleaner 22 is connected to the fixed pipe 20 through the connecting pipe 21, which allows the cleaning roller 19 to generate suction. While guiding the packaging paper into the device, it can clean the dust and impurities on both sides of the packaging paper. The packaging paper passes between the first coating roller 3 and the first pressure roller 4. While the first coating roller 3 rotates and conveys the packaging paper, it applies the coating from the first coating box 2 to the lower surface of the packaging paper. The motor 16 at the bottom of the inner side of the housing 1 drives the comma roller 17 to rotate and scrape off the excess coating on the surface of the packaging paper. The heater 23 transfers heat to the inside of the first drying hood 25 through the first conveying pipe 24 to dry the coating on the surface of the packaging paper coated by the first coating roller 3. The dried packaging paper is then conveyed to the second coating roller by the guide roller 5. Between the second pressure roller 7 and the second pressure roller 8, the packaging paper is flipped over simultaneously. The second coating roller 7 coats the coating inside the second coating box 6 onto the other side of the packaging paper, allowing the device to coat both sides simultaneously. The second conveying pipe 26 transports the heat inside the heater 23 to the inside of the second drying hood 27, heating and drying the surface of the packaging paper coated by the second coating roller 7, thus accelerating the curing effect of the coating. The material level sensor 10 detects the amount of coating inside the first coating box 2 and the second coating box 6. When the amount of coating reaches the set value, it automatically replenishes the material through the replenishing pipe 11. When the output end of the hydraulic rod 15 extends or retracts, it drives the support plate 13 to rotate a certain angle around the center of the connection between the fixed block 12 and the support plate 13 through the fixed rod 14. The position of the comma roller 17 is adjusted according to the different coating thicknesses, making operation convenient.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
