[0025] As Figures 1-3Also shown, there are brush rollers 4, the left and right parts of the cleaning pool 1 are rotatably connected with brush rollers 4, the brush rollers 4 are opposite to the adjacent conveying rollers in the rotating direction, the height of the right brush roller 4 is higher than that of the left brush roller 4, the left brush roller 4 and the conveying rollers of the left part of the cleaning pool 1 are connected with gears 5 at the front and back parts, the gears 5 adjacent to each other are engaged, a servo motor 6 is installed at the front side of the right part of the cleaning pool 1, the output shaft of the servo motor 6 is connected with the right brush roller 4, spraying assemblies 7 are installed at the left and right parts of the cleaning pool 1, the spraying assemblies 7 can spray the adjacent brush rollers 4, an arc-shaped baffle 8 is installed at the upper side of the right part of the cleaning pool 1, shielding assemblies 11 are slidably connected at the inner sides of the front and back parts of the middle part of the cleaning pool 1, damping springs are connected between the shielding assemblies 11 and the cleaning pool 1, adjusting rollers 9 are rotatably connected between the shielding assemblies 11, locking pieces 10 are rotatably connected at the front and back sides of the adjusting rollers 9, the locking pieces 10 are threadedly connected with the cleaning pool 1, the front and back parts of the conveying rollers on the cleaning pool 1 are provided with limit adjusting mechanisms 13, the front and back sides of the adjusting rollers 9 are also provided with limit adjusting mechanisms 13.
[0026] It should be noted that the cold-rolled steel strip is a kind of steel produced by cold rolling process, which has high dimensional accuracy, good surface quality and excellent mechanical properties. In order to ensure the surface quality and the smooth progress of subsequent processing, it is usually necessary to clean and dry the surface of the steel strip to remove oil stains, oxides and other impurities, improve the surface quality of the steel strip and the adhesion of the subsequent coating. The cold-rolled steel strip is placed from the right side between the arc-shaped baffle 8 and the cleaning tank 1, and then passes through the right side of the brush roller 4 and the conveying roller and the lower side of the adjusting roller 9 and the upper side of the conveying roller and the brush roller 4 on the right side in turn. The adjacent conveying rollers are driven by the driving motor to rotate, and then the remaining conveying rollers and the conveying belt are successively moved, so that the cold-rolled steel strip continuously transmits to the left. During the conveying process of the cold-rolled steel strip, the spraying assembly 7 sprays cleaning agent on the cold-rolled steel strip, and the servo motor 6 operates to drive the adjacent brush roller 4 to move away from the adjacent conveying roller, so that the brush roller 4 cleans the upper part of the cold-rolled steel strip. The arc-shaped baffle 8 can shield the cleaning agent when the right brush roller 4 cleans the cold-rolled steel strip to prevent the cleaning agent from splashing outward. At the same time, the driving motor operates to drive the conveying roller on the left side of the cleaning tank 1 to rotate, which makes the adjacent brush roller 4 rotate away from the conveying roller on the left side of the cleaning tank 1, so that the brush roller 4 cleans the lower part of the cold-rolled steel strip. The brush roller 4 dynamically cleans the cold-rolled steel strip, which can improve the cleaning strength of the original soaking cleaning and improve the cleaning effect. The spraying assembly 7 sprays cleaning agent on the brush roller 4, which can clean the brush roller 4 while ensuring the cleaning effect of the cold-rolled steel strip, so as to avoid the residues on the brush roller 4. During the conveying process of the cold-rolled steel strip, the cold-rolled steel strip is conveyed by the conveying roller, which may cause unbalanced tension, which may cause the cold-rolled steel strip to stretch or compress, affecting the specifications and properties of the cold-rolled steel strip. The height of the adjusting roller 9 can be adjusted by adjusting the height of the shielding assembly 11, and then the tension of the cold-rolled steel strip during transportation can be adjusted according to the actual production requirements. Rotate the locking piece 10 to make the shielding assembly 11 separate from the locking state of the locking piece 10, then slide the shielding assembly 11 to the appropriate position, and rotate the locking piece 10 again to lock the shielding assembly 11. The shielding assembly 11 can shield the liquid during cleaning to prevent it from overflowing. The cleaned cold-rolled steel strip is conveyed to the left into the drying cavity 12, and the heating pipe 122 heats and dries the cold-rolled steel strip to keep the surface of the cold-rolled steel strip dry.

[0029] It should be noted that, in order to prevent the cold-rolled steel strip from being deviated during the conveying process, the limiting adjustment mechanism 13 can be used to limit the position, when the cold-rolled steel strip is pulled, the clamping bolt 132 can be upwardly pushed, the reset spring 133 is stretched, so that the sliding piece 131 is separated from the adjusting roller 9 and the adjacent conveying roller, then the sliding piece 131 is slid to the appropriate position according to the specification of the cold-rolled steel strip, the clamping bolt 132 is released, and the reset spring 133 is reset, so that the sliding piece 131 is again in the locked state with the adjusting roller 9 and the adjacent conveying roller, and the sliding piece 131 plays a limiting role on the cold-rolled steel strip.
