[0027] It also includes:

[0028] Paint box 3 is fixedly installed on the bottom wall of the inner casing 1. A coating roller 17 is rotatably connected to the inner casing 1 via a bearing, and the lower part of the coating roller 17 is located inside the paint box 3. A No. 1 motor 4 is fixedly installed on the front side wall of the casing 1, and the output shaft of the No. 1 motor 4 is connected to the coating roller 17.

[0029] The movable frame 5 is slidably mounted inside the housing 1 at the position above and to the right of the coating roller 17 via a slide rail pair. A second motor 6 is fixedly mounted on the right side wall of the housing 1. A lead screw 7 is fixedly mounted on the output shaft of the second motor 6. The lead screw 7 is rotatably mounted inside the housing 1 via a bearing, and one end of the lead screw 7 is rotatably inserted into the movable frame 5 via a thread.

[0030] A metering roller 8 is rotatably mounted on a movable frame 5 via bearings. A No. 3 motor 9 is fixedly mounted on the front side of the movable frame 5, and the output shaft of the No. 3 motor 9 is connected to the metering roller 8. A cleaning mechanism 10 connected to the metering roller 8 is provided on the movable frame 5. A guide frame 15 is fixedly mounted on the upper right side of the paint box 3, and the guide frame 15 is located below the metering roller 8. The guide frame 15 can provide flow guidance for excess paint falling from the metering roller 8. A filter plate 16 is fixedly mounted on the guide frame 15, and the filter plate 16 can filter the excess paint to further ensure the quality of the recovered excess paint.

[0031] The scraper 11 is obliquely and fixedly installed at the lower part of the movable frame 5, and the scraper 11 is located above the paint box 3;

[0032] The cleaning mechanism 10 includes:

[0033] Rotating rod 10-1 is rotatably mounted in the movable frame 5 via bearings. Rotating rod 10-1 is connected to the quantitative roller 8 via pulleys and belts. Sliding strip 10-2 is movably sleeved on rotating rod 10-1. Sliding strip 10-2 is slidably mounted in the sliding groove 12 opened on the movable frame 5.

[0034] A cleaning cloth 10-3 is fixedly mounted on a sliding bar 10-2 and is movably mounted against a metering roller 8. A wastewater box 14 is fixedly mounted at the lower part of the moving frame 5 below the cleaning cloth 10-3. The wastewater box 14 can collect the waste liquid dripping from the cleaning cloth 10-3.
