Description

Technical Field

[0001] The utility model relates to the technical field of coating machines, in particular to an anti-bonding coating mechanism for a coating machine. Background Technique

[0002] Coating machines are mainly used in the surface coating process production of films, papers, etc. Through the coating rollers arranged inside them, the coating rollers can achieve simple coating operations, which are suitable for the formulation of coatings on various substrates. In this way, coatings can be applied to many substrates, including papers, cardboard, plastic films, foils, metal plates, glass plates, wooden boards, and so on.

[0003] When traditional coating equipment is in use, after using a coating roller to coat a substrate, a scraper is used to scrape off the coating liquid attached to the outer wall of the substrate to ensure that the coating thickness is uniform. However, when the traditional scraper is in use, a large amount of coating liquid will adhere to the outer wall of the scraper, and the traditional equipment cannot clean the outer wall of the scraper, resulting in the adhesion of the coating liquid on the outer wall of the scraper, thus affecting the normal scraping effect of the scraper.

[0023] By providing a back roller 2 and a feeding roller 3 on the outer wall of the support frame 1, and a material box 4 on the outer wall of the support frame 1, there is a coating liquid in the inner cavity of the material box 4. Under the action of the rotation of the feeding roller 3, the coating liquid can be coated on the outer wall of the base material 9, so that the coating liquid can be evenly attached to the outer wall of the base material 9.

[0024] In a preferred embodiment: The outer wall of the end of the transmission belt 6 away from the drive motor 5 is in rolling connection with the outer wall of the feeding roller 3, and the outer wall of the first driven gear 7 is meshed with the outer wall of the first driving gear 8.

[0025] By providing a drive motor 5 on the outer wall of the support frame 1 and a transmission belt 6 on the power output shaft of the drive motor 5, the power of the drive motor 5 can be transmitted to the outer wall of the feeding roller 3 under the action of the transmission belt 6, so that the feeding roller 3 can rotate under the action of the drive motor 5. And a first driving gear 8 is provided on the outer wall of the feeding roller 3 to drive the first driven gear 7, so that the rotation directions of the back roller 2 and the feeding roller 3 are opposite, thereby realizing the driving of the base material 9.

[0026] In a preferred embodiment: The outer wall of the second driving gear 13 is meshed with the outer wall of the second driven gear 11, and the outer wall diameter of the second driving gear 13 is smaller than the outer wall diameter of the second driven gear 11.

[0027] By providing a drive motor 12 on the outer wall of the support frame 1, the drive motor 12 can drive the second driving gear 13 and drive the rotation of the second driving gear 13 and the second driven gear 11, so that the rotating rod 10 can rotate in the inner cavity of the support frame 1, thereby driving the rotation of the lower scraper 15 and the upper scraper 14, so that the outer wall of the upper scraper 14 or the lower scraper 15 can contact the outer wall of the base material 9 to scrape off the residual coating liquid on the outer wall of the base material 9, so that the thickness of the coating liquid coated on the outer wall of the base material 9 can be more uniform.

[0028] In a preferred embodiment: The included angle between the outer walls of the lower scraper 15 and the upper scraper 14 is 45°, and the power output shaft of the cleaning motor 19 is connected to the outer wall of the drive rod 16.

[0029] By providing an upper scraper 14 and a lower scraper 15 on the outer wall of the rotating rod 10, and the included angle between the upper scraper 14 and the lower scraper 15 is 45°. When there is more coating liquid attached to the outer wall of the upper scraper 14, at this time, the outer wall of the upper scraper 14 cannot well scrape the outer wall of the base material 9, resulting in uneven coating liquid on the outer wall of the base material 9. At this time, rotate the rotating rod 10 again to make the lower scraper 15 move upward to replace the upper scraper 14 to scrape the outer wall of the base material 9.

[0030] In a preferred embodiment: the outer wall width of the upper squeegee 14 is greater than the outer wall width of the substrate 9, an internal thread is provided on the inner wall of the cleaning block 18, and the internal thread on the inner wall of the cleaning block 18 meshes with the external thread on the outer wall of the driving rod 16.

[0031] Through the internal thread provided on the inner wall of the cleaning block 18, when the cleaning motor 19 drives the driving rod 16 to rotate, the driving rod 16 can be made to rotate under the action of the cleaning motor 19. Furthermore, during the rotation of the driving rod 16, the cleaning block 18 is driven to move back and forth along the outer wall of the limiting rod 17. Thus, during the movement, the outer wall of the upper squeegee 14 is cleaned under the action of the cleaning block 18, preventing a large amount of coating liquid from adhering to the outer wall of the upper squeegee 14 and affecting its coating effect.

[0032] In a preferred embodiment: the inner wall shape of the cleaning block 18 matches the outer wall shape of the upper squeegee 14, a limiting hole is provided on the outer wall of the cleaning block 18, and the inner diameter of the limiting hole matches the outer diameter of the limiting rod 17.

[0033] Through the cleaning block 18 provided on the outer wall of the limiting rod 17, when the cleaning block 18 moves under the action of the driving rod 16, the outer wall of the upper squeegee 14 can be scraped under the action of the inner wall of the cleaning block 18, removing the coating liquid adhering to the outer wall of the upper squeegee 14. Furthermore, the upper squeegee 14 can better scrape the outer wall of the substrate 9.

[0034] Working principle: During the use of the above-mentioned device, when it is necessary to use the device to coat the outer wall of the substrate 9, coating liquid is added into the inner cavity of the material box 4. Then, the substrate 9 is passed through between the outer walls of the back roller 2 and the feeding roller 3. At this time, the device can be started. During the rotation of the back roller 2 and the feeding roller 3, the coating of the outer wall of the substrate 9 is realized. And when the substrate 9 moves outward from between the outer walls of the back roller 2 and the feeding roller 3, under the action of the upper scraping plate 14, the outer wall of the substrate 9 can be scraped, so that the coating liquid attached to the outer wall of the substrate 9 can be scraped off, ensuring that the thickness of the coating liquid attached to the outer wall of the substrate 9 is more uniform. As the upper scraping plate 14 continuously scrapes, the coating liquid will adhere to the outer wall of the upper scraping plate 14, resulting in an increase in the thickness of the outer wall of the upper scraping plate 14, causing the edge of the outer wall of the upper scraping plate 14 to be not sharp enough, and thus unable to scrape the outer wall of the substrate 9 well. At this time, under the action of the driving motor 12, the rotation of the second driving gear 13 and the second driven gear 11 is driven. By controlling the starting time of the driving motor 12, the rotating rod 10 rotates 45°, and the outer wall of the lower scraping plate 15 below is attached to the outer wall of the substrate 9. Under the action of the lower scraping plate 15, the outer wall of the substrate 9 is scraped. At this time, the cleaning motor 19 is started. Under the action of the cleaning motor 19, the rotation of the driving rod 16 is driven, so that the cleaning block 18 moves along the outer wall of the limiting rod 17 to clean the outer wall of the upper scraping plate 14, ensuring that the outer wall of the upper scraping plate 14 maintains a relatively sharp state and better scrapes the outer wall of the substrate 9. If too much coating liquid adheres to the outer wall of the lower scraping plate 15, the cleaning block 18 is used for cleaning in the same way to ensure the stable working state of the upper scraping plate 14 and the lower scraping plate 15, and avoid a large amount of coating liquid adhering to the outer wall of the upper scraping plate 14.
