[0037] With reference to Figures 1 to 5 , the steel roller wiping device provided by an example of the present application comprises a rack 100, a wiping mechanism 300 and a spraying mechanism 400 arranged on the rack 100.

[0038] The rack 100 comprises two wall plates and connecting rods for connecting the two wall plates, and two ends of the steel roller 200 are rotatably connected to the two wall plates, respectively.

[0039] The wiping mechanism 300 is located on one side of the steel roller 200, and the spraying mechanism 400 is located above the wiping mechanism 300.

[0040] The wiping mechanism 300 comprises a supporting roller 310, a plurality of wiping sponges 320 arranged on the supporting roller 310, and a first driving assembly 330 for driving the supporting roller 310 to rotate. The plurality of wiping sponges 320 are arranged in a circular array along the axis of the supporting roller 310. The wiping sponge 320 has a cuboid structure, and the length direction of the wiping sponge 320 extends along the axial direction of the supporting roller 310. The supporting roller 310 is parallel to the steel roller 200.

[0041] Specifically, the number of the wiping sponges 320 is four.

[0042] Further, the spraying mechanism 400 is used for spraying cleaning liquid onto the wiping sponges 320, and comprises a liquid supply assembly 410, a spraying pipe 420, and a plurality of spray heads 430 arranged on the spraying pipe 420. The liquid supply assembly 410 is used for providing cleaning liquid into the spraying pipe 420.

The spraying pipe 420 is parallel to the supporting roller 310 and located above the supporting roller 310. The plurality of spray heads 430 are all directed towards the supporting roller 310.

[0043] When the surface of the steel roller 200 is adhered with contaminants, the wiping sponges 320 are fixed on the support roller 310 on the side of the support roller 310 far away from the steel roller 200, the first driving assembly 330 drives the support roller 310 to rotate, the support roller 310 drives the wiping sponges 320 to rotate around the axis of the support roller 310, when one of the wiping sponges 320 rotates to the top of the support roller 310, the first driving assembly 330 stops working. Then, the liquid supply assembly 410 supplies cleaning liquid into the spraying pipe 420, the cleaning liquid is sprayed from the spraying head 430 to the wiping sponge 320 on the top of the support roller 310, after the wiping sponge 320 absorbs the cleaning liquid, the liquid supply assembly 410 stops working. Then, the first driving assembly 330 continues to drive the support roller 310 to rotate by 90 degrees, so that the wiping sponge 320 absorbing the cleaning liquid abuts against the roller surface of the steel roller 200, and the other wiping sponge 320 is located on the top of the support roller 310, then the steel roller 200 rotates, the wiping sponge 320 absorbing the cleaning liquid wipes the contaminants on the roller surface of the steel roller 200, at the same time, the liquid supply assembly 410 supplies cleaning liquid into the spraying pipe 420, the cleaning liquid is sprayed from the spraying head 430 to the wiping sponge 320 on the top of the support roller 310.

If the contaminants on the roller surface of the steel roller 200 are wiped clean, at this time, the spraying mechanism 400 does not need to spray the cleaning liquid to the wiping sponge 320 on the top of the support roller 310, then the first driving assembly 330 continues to drive the support roller 310 to rotate by 90 degrees, so that the dry wiping sponge 320 abuts against the roller surface of the steel roller 200, then the steel roller 200 rotates, the dry wiping sponge 320 wipes the liquid remaining on the roller surface of the steel roller 200.
