Description

Technical Field

[0001] The utility model relates to the technical field of coating equipment, and more specifically, to a coating mechanism. Background Art

[0002] The coating roller can realize the coating operation and is suitable for the formulation of coating films on various substrates. In this way, the coating can be applied to the surface of substrates such as paper and film. The coating roller is partially immersed in the coating in the coating box. When the coating roller rotates, the coating will adhere to the surface of the coating roller and coat the substrate;

[0003] The coating roller has a concave and convex texture on its surface under the microscopic level. After coating, the coating roller needs to be scraped off the residual paint on the surface of the coating roller by a scraper, and then the paint is re-applied. However, due to the texture on the surface of the coating roller, the existing scraper cannot deeply penetrate into the surface texture of the coating roller to scrape the material, resulting in paint residue on the surface of the coating roller after cleaning by the scraper. After long-term use, the paint remaining on the surface of the coating roller will solidify, which will not only affect the coating quality, but also make the coating roller difficult to clean. Therefore, it is urgently needed to improve this. Utility Model Content

DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] like Figures 1 to 4 As shown, a coating mechanism comprises a frame 1, wherein a coating box 2 and a coating roller 3 are arranged inside the frame 1, wherein the coating roller 3 is located inside the coating box 2, wherein the coating box 2 is provided with coating, wherein the coating roller 3 is partially immersed in the coating, wherein both ends of the coating roller 3 are connected to the frame 1, wherein a rotatable cleaning roller 4 and a second scraping roller 8 are arranged on both sides of the coating roller 3, wherein the cleaning roller 4 comprises a central roller 41, wherein a sponge sleeve 42 is fixed to the outside of the central roller 41, wherein the sponge sleeve 42 abuts against and squeezes the surface of the coating roller 3, and wherein a gap between the surface of the second scraping roller 8 and the surface of the coating roller 3 is formed. In coordination, the cleaning roller 4 and the second scraper roller 8 are both higher than the coating. The coating direction of the coating roller 3 in this embodiment rotates counterclockwise. By setting the second scraper roller 8, the coating on the surface of the coating roller 3 can be evenly scraped, thereby improving the coating quality. By setting the cleaning roller 4, when the cleaning roller 4 is normally cleaned, the coating roller 3 drives the cleaning roller 4 to rotate, and squeezes the surface of the coating roller 3 through the surface of the sponge cover 42, so that the surface of the sponge cover 42 can penetrate into the depression on the surface of the coating roller 3, thereby cleaning the surface of the coating roller 3, greatly improving the surface cleaning quality of the coating roller 3, and effectively ensuring the coating effect.

[0025] The cleaning roller 4 is provided with a rotatable first scraper roller 5 on the side away from the coating roller 3, and both ends of the first scraper roller 5 are connected to the frame 1, and the first scraper roller 5 is connected to the frame 1 through bearings. The surface of the first scraper roller 5 abuts and squeezes the surface of the sponge sleeve 42. When the cleaning roller 4 cleans the surface of the coating roller 3, the paint on the surface of the coating roller 3 will be transferred to the surface of the cleaning roller 4. Through the cooperation between the cleaning roller 4 and the first scraper roller 5, the cleaning roller 4 can be cleaned, and the paint on the surface of the cleaning roller 4 can be transferred to the surface of the first scraper roller 5, thereby improving the service life of the cleaning roller 4 and further improving the cleaning effect of the cleaning roller 4.

[0026] A scraper is provided on the side of the first scraper roller 5 away from the cleaning roller 4, and both ends of the scraper are fixed to the frame 1. Connecting rods 77 are provided at both ends of the connecting plate 7, and the connecting rods 77 are connected to the frame 1. The scraper includes a rubber block 6 and a connecting plate 7. The connecting plate 7 is connected to the rubber block 6. A limiting rib 61 is provided on one side of the rubber block 6, and a limiting groove 71 is provided on one side of the connecting plate 7. The limiting rib 61 is inserted into the limiting groove 71 and fixed. The rubber block 6 abuts against the side of the first scraper roller 5, and the scraper is designed to be inclined upward toward the first scraper roller 5. By setting the scraper, the paint on the surface of the first scraper roller 5 can be scraped off, and the first scraper roller 5 and the scraper are both located above the paint box 2, so that the paint scraped off by the scraper can fall into the paint box 2.

[0027] The surface of the connecting plate 7 is provided with a plurality of first through holes 75 and a plurality of second through holes 76, wherein the plurality of first through holes 75 are arranged side by side and spaced apart, and the plurality of second through holes 76 are arranged side by side and spaced apart, and the first through holes 75 and the second through holes 76 are arranged in a staggered manner. During normal cleaning, the cleaning roller 4 rotates clockwise, thereby driving the first scraping roller 5 to rotate counterclockwise, and the scraped paint is located on the upper surface of the scraper and slides down from the first through holes 75 or the second through holes 76 along the upper surface of the scraper, thereby effectively preventing the paint from accumulating on the scraper surface.

[0028] The rubber block 6 is provided with a first rib 62 on one side facing the connecting plate 7. The first rib 62 is located on the upper surface of the connecting plate 7. By providing the first rib 62, when the scraper is effectively used to clean the surface of the first scraper roller 5, the paint falls into the matching gap between the limiting rib 61 and the limiting groove 71.

[0029] Among them, the cleaning roller 4 is driven by a driving mechanism, and the driving mechanism includes a motor 9. A driving wheel 91 is fixed to the end of the driving shaft of the motor 9. A cam 43 is provided at one end of the center roller 41. A driven wheel 44 is fixed to the outer side of the cam 43. The driving wheel 91 is connected to the driven wheel 44 through a belt 100. After the coating roller 3 has worked for a period of time, the surface of the coating roller 3 needs to be vigorously cleaned. Specifically, the cleaning roller 4 is driven by the motor 9 to rotate counterclockwise rapidly, so that the surface of the coating roller 3 can be vigorously cleaned, and the cleaning roller 4 can drive the first scraper roller 5 to rotate clockwise. At this time, the paint on the surface of the first scraper roller 5 scraped off by the scraper is located below the scraper.

[0030] A second rib 72 is provided on the side of the lower part of the connecting plate 7 facing the rubber block 6, and an arc groove 73 is provided on the side of the second rib 72 away from the rubber block 6. The lower end of the second rib 72 transitions to the lower part of the rubber block 6 via an inclined surface 74. Since the paint is a viscous emulsion and becomes more viscous when transferred to the scraper, the inclined surface 74 can guide the paint in the strong cleaning state, and the second rib 72 can make the paint fall into the paint box 2 better, and the arc groove 73 can effectively prevent the paint from condensing on the side of the second rib 72.
