[0008] In one embodiment, a first scraper and a second scraper are disposed on both sides of the base; wherein the first scraper is suitable for being mounted on the base through a first pressing plate.

[0009] In one embodiment, a first installation position is provided on both side walls of the base; and the second scraper is arranged in the first installation position.

[0010] In one embodiment, the first scraper is located outside the second scraper and abuts against the second scraper.

[0011] In one embodiment, a first scraper is disposed on at least one side of the base; and a second scraper is disposed on the base; wherein the first scraper is mounted on the base via a first pressing plate.

[0012] In one embodiment, a second installation position is provided on a side wall of the base; the second scraper is suitable for being arranged in the second installation position through the first support plate.

[0013] In one embodiment, a second support plate and a third support plate are provided on the base; wherein two ends of the second support plate are respectively abutted against the corresponding first scraper blade; and two ends of the third support plate are respectively abutted against the corresponding second scraper blade.

[0014] In one embodiment, a drainage channel is left between the first scraper and the second scraper.

[0015] In a second aspect, the utility model further provides a coating device, which comprises: a coating knife cleaning scraper device as described above; and a moving crossbeam; wherein the coating knife cleaning scraper device is arranged on the moving crossbeam.

[0016] The beneficial effect of the utility model is that the first scraper of the scraper device for cleaning the coating knife is used to clean the side wall of the coating knife, and the waste liquid cleaned out will flow along the side wall to the bottom blade of the coating knife. Therefore, the second scraper is provided in this scheme to clean the bottom blade to prevent waste liquid from remaining on the coating knife.
