Abstract
Description
Technical Field
[0001] This utility model belongs to the field of micro-concave coating technology, specifically relating to a micro-concave coating device for sunscreen film. Background Technology
[0002] A micro-grooving device is a device that coats a membrane surface with micro-grooves to improve the membrane's performance.
[0003] In existing microgravure coating devices, after the microgravure roller coats the sunscreen film, some residual coating material remains unevenly on the outer wall of the roller and adheres for a long time, affecting the uniform coating of the film and resulting in poor practicality. In addition, the coating tank in existing microgravure coating devices lacks a stirring device, and the coating material in the tank will settle after a long period of accumulation.
[0004] Therefore, a micro-grooving coating device for sunscreen film is proposed, which has a scraper structure to make the coating on the micro-grooving roller uniform and increase the smoothness of the coating. The coating tank has a stirring structure to avoid the problem of coating sedimentation and clumping during long-term operation. Utility Model Content
[0005] To overcome the problem that some residual paint remains unevenly on the outer wall of the micro-gravure roller after coating the sunscreen film in existing micro-gravure coating devices, which affects the uniform coating of the film, the paint tank in the existing micro-gravure coating devices lacks a stirring device, and the paint in the tank will settle after a long period of accumulation.
[0006] The technical solution of this utility model is as follows: a sunscreen film micro-concave coating device, including a base plate; a paint tank is fixedly connected to the upper end of the base plate, and two first fixing plates are fixedly connected to the upper end of the base plate. The two first fixing plates are located at the front and rear ends of the paint tank. A first motor is fixedly connected to the front end face of the first fixing plate. A micro-concave roller is fixedly connected to the outer wall of the output shaft of the first motor. The micro-concave roller is located between the two first fixing plates. An L-shaped plate is fixedly connected to the upper end of the base plate. An auxiliary roller assembly is provided at the front end of the inner wall of the L-shaped plate. The auxiliary roller assembly includes a first fixing post, a limiting ring, and an auxiliary roller. Two first fixing posts are fixedly connected to the front end of the inner wall of the L-shaped plate. An auxiliary roller is rotatably arranged on the outer wall of the first fixing posts. Limiting rings are fixedly connected to the front and rear ends of the auxiliary roller.
[0007] Preferably, a sunscreen film is rotatably mounted on the outer wall of the auxiliary roller, and the sunscreen film is in contact with the outer wall of the micro-concave roller. The sunscreen film is driven by two auxiliary rollers, which straighten the sunscreen film so that it can make flat contact with the micro-concave roller, ensuring the flatness of the coating. By setting a scraper above the micro-concave roller, the coating on the surface of the micro-concave roller can be scraped evenly, so that the coating can be evenly coated on the surface of the sunscreen film. After coating, the coating on the surface of the micro-concave roller can be cleaned by the scraper, which solves the problem of residual coating on the micro-concave roller adhering to the surface. By setting a limit rod, the angle of the scraper can be maintained to avoid damage to the surface of the micro-concave roller. By installing a stirring plate in the coating tank, the problem of coating sedimentation and clumping in the coating tank can be avoided, ensuring the uniformity of the coating. By installing multiple ultraviolet lamps at the outlet, ultraviolet light irradiates the coating, causing the photosensitizer in the coating to undergo a chemical reaction, which can quickly solidify the coating on the surface of the sunscreen film, which helps to enhance the adhesion between the coating and the sunscreen film, ensuring that the coating adheres firmly.
[0008] Preferably, a first groove is provided through the right end face of the L-shaped plate, and a second groove is provided through the bottom of the first groove. The sun protection film enters through the first groove, adheres to the outer wall of the two auxiliary rollers, and then extends through the second groove to the outside of the L-shaped plate.
[0009] Preferably, the scraping assembly includes a second fixing plate, a second fixing post, a round hole, a second motor, and a scraper; two second fixing plates are fixedly connected to the upper end of the base plate, a round hole is opened through the front end of the second fixing plate, a second fixing post is rotatably arranged on the inner wall of the round hole, a second motor is fixedly connected to the front end of the second fixing plate, the output shaft of the second motor is fixedly connected to the second fixing post, and a scraper is fixedly connected to the outer wall of the second fixing post.
[0010] Preferably, a limiting plate is fixed to the left end of the first fixed plate, and a limiting rod is fixed to the rear end of the limiting plate, with the limiting rod located below the scraper.
[0011] Preferably, the mixing assembly includes a third motor, a third fixed column, and mixing plates; the third motor is fixedly connected to the left end of the paint tank, the output shaft of the third motor is fixedly connected to the third fixed column, and multiple mixing plates are fixedly connected to the outer wall of the third fixed column.
[0012] Preferably, the UV lamp assembly includes support columns, a protective cover, and UV lamps; four support columns are fixed to the upper end of the base plate, a protective cover is fixed to the upper end of the support columns, and multiple UV lamps are fixed to the inner wall of the protective cover.
[0013] The beneficial effects of this invention are as follows: By setting a scraper above the micro-concave roller, the coating on the surface of the micro-concave roller can be scraped evenly, allowing the coating to be evenly applied to the surface of the sun protection film. After coating, the scraper can be used to clean the coating residue on the surface of the micro-concave roller. By setting a limiting rod below the scraper, the angle of the scraper can be maintained, avoiding damage to the surface of the micro-concave roller. By installing a stirring plate in the coating tank, continuous stirring during the coating process can prevent the coating in the coating tank from settling and clumping, ensuring the uniformity of the coating. By installing multiple ultraviolet lamps at the outlet, the coating on the surface of the sun protection film can be quickly solidified, which helps to enhance the adhesion between the coating and the sun protection film, preventing the coating from peeling off.

An auxiliary roller 103 is rotatably arranged on the outer wall of the first fixing posts 101. The front and rear ends of the auxiliary roller 103 are fixedly connected to the limiting rings 102.
[0023] Please see Figure 3 In this embodiment, the scraping assembly includes a second fixing plate 201, a circular hole 202, a second fixing post 203, a second motor 204, and a scraper 205. Two second fixing plates 201 are fixedly connected to the upper end of the base plate 1. A circular hole 202 is opened through the front end of the second fixing plate 201. The second fixing post 203 is rotatably arranged on the inner wall of the circular hole 202. The second motor 204 is fixedly connected to the front end of the second fixing plate 201. The output shaft of the second motor 204 is fixedly connected to the second fixing post 203. The scraper 205 is fixedly connected to the outer wall of the second fixing post 203. The scraper 205 can scrape the coating on the surface of the micro-concave roller 6 evenly, so that the coating can be evenly coated on the surface of the sunscreen film 7. After the coating is completed, the coating on the surface of the micro-concave roller 6 can be cleaned by the scraper 205.
[0024] Please see Figure 4 In this embodiment, a limiting plate 10 is fixedly connected to the left end of the first fixing plate 4, and a limiting rod 11 is fixedly connected to the rear end of the limiting plate 10. The limiting rod 11 is located below the scraper 205, which can maintain the angle of the scraper 205 and avoid damage to the surface of the micro-concave roller 6.
[0025] Please see Figure 5 In this embodiment, the stirring assembly includes a third motor 301, a third fixed column 302, and a stirring plate 303; the third motor 301 is fixedly connected to the left end of the paint tank 3, the output shaft of the third motor 301 is fixedly connected to the third fixed column 302, and multiple stirring plates 303 are fixedly connected to the outer wall of the third fixed column 302.
