Description

Technical Field

[0001] The present application relates to the field of coating technology, and in particular to a micro-dimpled coating machine. Background Art

[0002] Micro-concave coating uses a scraper to closely contact the surface of the micro-concave anilox roller, and controls the uniformity and thickness of the slurry by scraping off excess slurry with the scraper, and then coating the slurry on the film.

[0003] Since the uniformity and thickness of the slurry are achieved by the cooperation of the scraper, the scraper is in a state of continuous contact with the slurry. Therefore, after the coating is completed, paint or dry glue will remain on the scraper, which may easily affect the effect of the next coating. Utility Model Content

The cylinder body of the first servo cylinder 21 is hinged to the side wall of the frame 1, and the piston rod of the first servo cylinder 21 is hinged to the roller frame 2. When the piston rod of the first servo cylinder 21 is telescopically moved, the roller frame 2 is driven to rotate.

[0040] The glue coating assembly includes a glue box 3 and a glue roller 31. The glue box 3 is arranged on the frame 1.

The glue roller 31 is driven by a motor, and the motor is connected to the motor shaft through a coupling. In the working state, the first servo cylinder 21 drives the roller frame 2 to rotate, driving the two pressure rollers 22 to approach the glue roller 31 and distribute on both sides of the glue roller 31, pressing the conveyed substrate down to contact the glue roller 31; the glue roller 31 rotates to apply the coating in the glue box 3 on the surface of the substrate.

[0041] like Figure 2The frame 1 is provided with a knife seat 4, a scraper 41 is hinged on the knife seat 4, a second servo cylinder 42 is provided on the knife seat 4 for driving the scraper 41 to rotate close to or away from the glue roller 31, a cylinder body of the second servo cylinder 42 is hinged to the knife seat 4, and a piston rod of the second servo cylinder 42 is hinged to the scraper 41. During coating, the second servo cylinder 42 drives the scraper 41 to rotate and abut against the glue roller 31 to scrape off excess paint on the glue roller 31.

[0042] like Figure 2 and Figure 3 The cleaning assembly 5 includes a base 51, a slide 52 and a cutter 53. The base 51 is slidably connected to the side wall of the frame 1 and moves along the height direction of the frame 1. The side wall of the frame 1 is provided with a third servo cylinder 55 for driving the base 51 to move. The cylinder body of the third servo cylinder 55 is connected to the base 51, and its piston rod faces downward and is connected to the side wall of the frame 1.

[0043] The slide 52 is slidably connected to the base 51 along a direction parallel to the length of the scraper 41 , and the distance that the slide 52 can move in one direction is greater than the length of the scraper 41 , so that the slide 52 can move to a position away from the end of the scraper 41 .

[0044] like Figure 2 and Figure 3 A support rod 54 is rotatably connected to the slide 52, and the rotation axis of the support rod 54 is parallel to the length direction of the scraper 41. The slide 52 is provided with a fourth servo cylinder 56 for driving the support rod 54 to rotate. The cylinder body of the fourth servo cylinder 56 is hinged to the slide 52, and the piston rod of the fourth servo cylinder 56 is hinged to the support rod 54. A positioning plate 57 for supporting the support rod 54 is provided on the side of the slide 52 facing the scraper 41.

[0045] like Figure 3 and Figure 4 The support rod 54 is connected to a knife frame 7 on one side away from the slide 52. The knife frame 7 is U-shaped and its opening faces the scraper 41. Two cutters 53 are provided in parallel and are both rotatably connected in the knife frame 7. The rotation axis of the cutters 53 is perpendicular to the length direction of the scraper 41. The two opposite sides of the two cutters 53 are connected to the inner wall of the knife frame 7 through springs 71.

[0047] Principle of the embodiment of the present application: During cleaning, the support rod 54 is supported on the positioning plate 57, and the cutter 53 is spaced apart from one end of the scraper 41. The servo motor 63 drives the pulley 61 to rotate, so that the synchronous belt 62 drives the slide 52 to move, and the slide 52 drives the knife frame 7 to move through the support rod 54, so that the cutter 53 moves and contacts the guide surface 8. During the movement of the two cutters 53 along the guide surface 8, the two cutters 53 gradually move away from each other and squeeze the spring 71. When the cutters 53 pass over the guide surface 8, the spring 71 is in a compressed state, so that the two cutters 53 maintain effective contact with the surface of the scraper 41 under the elastic force of the spring 71.

[0048] The two cutters 53 scrape off the glue on the surface of the scraper 41 during the movement along the scraper 41, and the cleaning cotton block wipes the scraped surface of the scraper 41; when the cutter 53 moves to the other end of the scraper 41, the servo motor 63 drives the pulley 61 to reverse, driving the cutter 53 to move back, and so on, until the surface of the scraper 41 is cleaned.

[0049] After cleaning, the knife frame 7 moves to a position away from the end of the scraper 41, the fourth servo cylinder 56 drives the support rod 54 to drive the knife frame 7 to rotate backward, and the third servo cylinder 55 drives the base 51 to move downward, so that the cleaning assembly 5 is located below the coater.

[0050] The above description is only a specific implementation of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the present invention, which should be included in the protection scope of the present invention.
