Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0024] Please refer to Figures 1 to 7 The present application provides a technical scheme: a steel web coating device, comprising a mobile frame 1, mobile wheels 101 are rotatably installed at both ends of the two side surfaces of the mobile frame 1, a mounting through slot 102 is provided in the middle of the upper surface of the mobile frame 1, a spraying assembly 3 is arranged in the mounting through slot 102, a pretreatment assembly 2 is rotatably installed between the inner walls on both sides of the mobile frame 1, the pretreatment assembly 2 comprises two oppositely arranged arc-shaped frames 201, each arc-shaped frame 201 is rotatably connected to the inner wall of the corresponding side of the mobile frame 1 through a first rotating shaft 202 on one side surface, second rotating shafts 203 are rotatably installed at both ends of the opposite side surfaces of the two arc-shaped frames 201, polishing rollers 204 are fixedly connected between the two second rotating shafts 203 at the same end, the two polishing rollers 204 are connected to a driving mechanism, and the two arc-shaped frames 201 are connected to an adjusting and limiting mechanism.

[0025] Please refer to Figure 5 and Figure 6 The driving mechanism comprises a driving motor 205 and two chain wheels 206, the driving motor 205 is fixedly installed on one side surface of one of the arc-shaped frames 201, one end of the output shaft of the driving motor 205 is fixedly connected to one end of the corresponding second rotating shaft 203 through a through hole, and the two chain wheels 206 are fixedly sleeved on the two second rotating shafts 203 at the same side, and the two chain wheels 206 are drivingly connected through a chain 207.

[0026] When the driving motor 205 is started to drive the corresponding polishing roller 204 to rotate, the two polishing rollers 204 are synchronously rotated through the cooperation of the sprocket 206 and the chain 207, the polishing efficiency is improved, and the uniformity of the polishing quality is ensured.

[0027] Further, the adjusting limiting mechanism includes two adjusting handles 208, each adjusting handle 208 is fixedly connected with the upper surface of the corresponding arc-shaped frame 201, and a sliding block 209 is fixedly sleeved on each end of each adjusting handle 208. The two sliding blocks 209 located on the same adjusting handle 208 are slidingly connected in the corresponding guide sliding groove 103, and the two guide sliding grooves 103 are throughly arranged on the upper surface of the moving trolley 1.

[0028] The two polishing rollers 204 have different roughnesses of the surfaces, and in the actual operation process, the two polishing rollers 204 can be switched and selected according to the different rust removal and flattening needs of the steel web surface. In the switching process, the two arc-shaped frames 201 are relatively rotated to form an inclined state by pulling the two adjusting handles 208, the two limiting springs 210 on the corresponding side are compressed, the polishing roller 204 located on the lower side contacts the steel web surface to perform the pretreatment work such as rust removal and spraying before polishing. After the polishing is completed, the adjusting handle 208 is loosened, and the two adjusting handles 208 are reset to make the two arc-shaped frames 201 return to the horizontal state, that is, the two polishing rollers 204 simultaneously separate from the steel web surface. The device is supported by the moving wheels 101, and because the weights of the two ends of the arc-shaped frame 201 are different, the elastic force of the limiting springs 210 at the two ends should be adjusted to keep the arc-shaped frame 201 in the horizontal state without external force in the actual setting, so as to avoid that the polishing roller 204 contacts the steel web surface in the normal state.
