AI Technical Summary
In existing gravure coating equipment, the coating liquid does not fully contact the surface of the aluminum foil roll when coating it, resulting in incomplete coating and affecting the coating effect.
The spacing between the pressure roller and the gravure roller is adjusted by a pressing mechanism. The aluminum foil roll is pressed by the pressure roller, and the coating liquid is spread evenly by a scraper head. The surface of the gravure roller after coating is cleaned by a cleaning brush to ensure that the coating liquid is completely applied.
This achieves more complete contact between the aluminum foil roll and the surface of the gravure roller, resulting in more complete application of the coating liquid and improved coating effect.

[0023] The following describes in detail, with reference to the accompanying drawings, a precision micro-gravure coating device for aluminum foil rolls according to an embodiment of the present invention.
[0024] Example 1
[0025] For easier understanding, please refer to Figures 1 to 3 An embodiment of a precision micro-gravure coating device for aluminum foil rolls provided by this utility model includes a housing 1, a gravure roller 3 installed inside the housing 1, and a pressing mechanism provided on the top of the housing 1.
[0026] The pressing mechanism includes a support frame 2, an adjusting screw 4, a sliding plate 5, a mounting frame 7, and a pressure roller 8. The support frame 2 is fixedly installed on the top of the housing 1, the sliding plate 5 is slidably connected inside the support frame 2, the adjusting screw 4 is threadedly connected inside the support frame 2, the mounting frame 7 is installed inside the sliding plate 5, and the pressure roller 8 is rotatably connected to the bottom end inside the mounting frame 7.
[0027] It should be noted that a servo motor is installed on one side of the housing 1, and the gravure roller 3 is installed at the output end of the servo motor. During use, the aluminum foil roll is conveyed between the pressure roller 8 and the gravure roller 3. The distance between the pressure roller 8 and the gravure roller 3 can be adjusted by rotating the adjusting screw 4, so as to adjust according to the thickness of the aluminum foil roll. During the conveying process, the aluminum foil roll is pressed by the pressure roller 8, so that the aluminum foil roll and the surface of the gravure roller 3 are in more complete contact, the coating liquid is applied more completely, and thus the coating effect is better.
[0028] In some embodiments, such as Figure 2 As shown, the bottom of the adjusting screw 4 is rotatably connected to the top of the sliding plate 5. A first spring 6 is fixedly installed on the sliding plate 5. A mounting bracket 7 is fixedly installed on one end of the first spring 6. There are two mounting brackets and two pressure rollers 8.
[0029] It should be noted that the first spring 6 can be used to support the mounting frame 7, and the two pressure rollers 8 can make the aluminum foil roll and the surface of the gravure roller 3 more closely contacted.
[0030] In some embodiments, such as Figure 2 As shown, a scraper head 9 is fixedly installed on the inner wall of the housing 1. The scraper head 9 fits into the side wall of the gravure roller 3. An injection pipe 10 is fixedly installed on one side of the housing 1.
[0031] It should be noted that by setting the scraper head 9, the coating liquid on the surface of the gravure roller 3 before coating can be scraped evenly, and by setting the filling pipe 10, the coating liquid can be added into the housing 1.
[0032] Example 2
[0033] In some embodiments, such as Figure 3As shown, a mounting component 11 is fixedly installed on the top of the housing 1, and a support rod 12 is fixedly installed on the top of the mounting component 11. A cleaning brush 14 is slidably connected inside the support rod 12 through a second spring 13. The working end of the cleaning brush 14 fits into the side wall of the gravure roller 3.
[0034] It should be noted that the second spring 13 can be used to support the cleaning brush 14, so that the cleaning brush 14 is in close contact with the surface of the gravure roller 3, thereby enabling the cleaning brush 14 to better clean the surface of the gravure roller 3 after coating and avoid affecting the coating effect of the next coating.
[0035] Working principle: During use, the aluminum foil roll is conveyed between the pressure roller 8 and the gravure roller 3. The gravure roller 3 is driven to rotate by the servo motor. The distance between the pressure roller 8 and the gravure roller 3 can be adjusted by rotating the adjusting screw 4, so as to adjust according to the thickness of the aluminum foil roll. During the conveying process, the pressure roller 8 holds the aluminum foil roll, so that the aluminum foil roll and the surface of the gravure roller 3 are in more complete contact, and the coating liquid is applied more completely. The scraper head 9 can scrape the coating liquid evenly on the surface of the gravure roller 3 before coating. The cleaning brush 14 can better clean the surface of the gravure roller 3 after coating to avoid affecting the coating effect of the next time.
