The invention relates to the technical field of aluminum roll cleaning, in particular to a surface treatment device and method for an aluminum roll, the surface treatment device comprises a main side plate and an auxiliary side plate, the aluminum roll is inserted between the main side plate and the auxiliary side plate, the lower ends of the main side plate and the auxiliary side plate are jointly provided with a collecting box, and the upper face and the
lower face of the aluminum roll abut against an upper
sponge wheel and a lower
sponge wheel correspondingly; positioning frames are installed in cavities of the upper
sponge wheel and the lower sponge wheel in a penetrating mode, the two ends of each positioning frame are rotationally connected with the main side plate and the auxiliary side plate, a liquid conveying
pipe is inserted into a cavity of each positioning frame, and a guide
pipe is fixedly connected to the side surface of the end, close to the main side plate, of each liquid conveying
pipe; through sponge wheel wiping, spray hot
water softening and deep cleaning and
drying of the cleaning wheel, oil stains and aluminum scraps are thoroughly removed, waste water can be recycled, the sponge wheel is low in cost, easy to replace, energy-saving and environment-friendly, oil accumulation and blockage of the pressing wheel are prevented through hot air, stable operation is guaranteed, and the aluminum coil
treatment quality and efficiency are greatly improved.
