Technical Field

[0001] This utility model relates to the field of anti-counterfeiting label coating technology, specifically an anti-counterfeiting label coating device. Background Technology

[0002] Anti-counterfeiting labels are special markings attached to product packaging or the product itself to verify the authenticity and legality of the product and prevent counterfeit and shoddy products from entering the market. Anti-counterfeiting label coating refers to the uniform application of specific anti-counterfeiting materials or coatings to the surface of a substrate (such as paper, plastic film, etc.) to form a coating with anti-counterfeiting functions.

[0003] During the anti-counterfeiting label coating process, when encountering a wrinkled substrate, the coating roller has difficulty smoothing out the wrinkles, affecting the uniformity of the anti-counterfeiting label coating and causing product defects. Therefore, an anti-counterfeiting label coating device is proposed to solve the above problems. Utility Model Content

[0017] 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.

[0018] Please see Figure 1-3 This embodiment of an anti-counterfeiting label coating device includes a chamber 1. A coating roller 2 is rotatably mounted on the upper part of the chamber 1. A motor is fixedly mounted on the back of the chamber 1. The output end of the motor passes through the chamber 1 and is fixedly connected to the rear end of the coating roller 2. Two pressure roller groups 3 are fixedly mounted on the top left end of the chamber 1. A tensioning mechanism 4 is provided on the top of the chamber 1 and between the two pressure roller groups 3. A pressing and cleaning mechanism 5 is provided on the top right end of the chamber 1. A receiving mechanism 6 is provided on the front bottom end of the chamber 1.

[0019] In this embodiment, the pressure roller group 3 consists of two circular rollers, which are vertically distributed on the top of the chamber 1.

[0020] In this embodiment, the pressing and cleaning mechanism 5 includes a U-shaped plate 51, a sliding hole 52, a sliding block 53, a second motor 54, a rotating shaft 55, a scraper 56, a pressing roller 57, and an electric push rod 58. The U-shaped plate 51 is fixedly installed on the top of the chamber 1 and above the coating roller 2. The front and back of the U-shaped plate 51 are provided with sliding holes 52. The sliding block 53 is slidably installed inside the sliding hole 52. The second motor 54 is fixedly installed on the back of the rear sliding block 53. The output end of the second motor 54 passes through the sliding block 53. The output end of the second motor 54 is fixedly installed with a rotating shaft 55. The rotating shaft 55 is rotatably connected to the front sliding block 53. The top of the outer peripheral wall of the rotating shaft 55 is fixedly installed with a scraper 56. The bottom of the outer peripheral wall of the rotating shaft 55 is provided with a pressing roller 57. The front and rear ends of the top of the U-shaped plate 51 are fixedly installed with electric push rods 58. The electric push rods 58 pass through the U-shaped plate 51 and are fixedly connected to the sliding block 53.

[0021] Specifically, operating the electric push rod 58 can bring the pressing roller 57 close to the coating roller 2, so that the substrate comes into contact with the upper arm of the coating roller 2 to perform the coating operation on the substrate; when it is necessary to clean the coating roller 2, the electric push rod 58 and the motor 54 can be operated to move the scraper 56 downward and make it contact the coating roller 2, and the scraper 56 can scrape off the coating adhering to the coating roller 2.

[0022] In this embodiment, the receiving mechanism 6 includes a linear module 61, a receiving box 62, and a baffle 63. The linear module 61 is fixedly installed at the bottom front of the container 1, the receiving box 62 is fixedly installed at the output end of the linear module 61, and the baffle 63 is fixedly installed on the back of the receiving box 62. A through hole is located on the front of the container 1 above the linear module 61, and the through hole matches the baffle 63.

[0023] Specifically, the linear module 61 can be operated to extend the receiving box 62 to the lower left of the coating roller 2, and the scraped paint can fall into the receiving box 62 for collection, making it convenient for users to handle. In addition, when performing coating operations, the linear module 61 can be operated to block the through hole with the baffle 63 to prevent paint leakage.

[0024] In this embodiment, the tensioning mechanism 4 includes a mounting frame 41, a limiting hole 42, a limiting block 43, a telescopic spring 44, and a tensioning roller 45. Two mounting frames 41 are fixedly installed on the top of the chamber 1 and between the two pressure roller groups 3. A limiting hole 42 is opened on the opposite side of each of the two mounting frames 41. A limiting block 43 is slidably installed inside the limiting hole 42. A telescopic spring 44 is fixedly installed at the top and bottom of the limiting block 43, with one end fixedly connected to the inner wall of the limiting hole 42. Tensioning rollers 45 are rotatably installed at the upper and lower ends of the opposite side of each of the two tensioning rollers 45.

[0025] Specifically, when coating the anti-counterfeiting label substrate, the substrate is passed sequentially through the left pressure roller group 3, the tension roller 45 and the right pressure roller group 3, and exits between the pressing roller 57 and the coating roller 2. During normal substrate transport, since the substrate is under tension, it will be given a downward pressing force when passing through the tension roller 45, compressing the lower telescopic spring 44 and stretching the upper telescopic spring 44. When there are wrinkles in the substrate, the tension roller 45 will move upward with the help of the spring's extension and contraction, thereby stretching the wrinkles. In this way, uneven coating is avoided.
