With the increasing demand of the manufacturing industry for metal strips such as steel strips, aluminum strips, copper strips and the like, it is necessary to improve the processing efficiency of the metal strips. Because steel, aluminum, copper, etc. belts are cast, the surface has an oxide layer. This affects the surface quality and requires a finishing process on the surface. In the finishing process of the metal strip blank, the design and manufacturing level of two procedures of uncoiling and surface milling can generate very important influence on the finishing process.

In the traditional process, metal strips are uncoiled by adopting power of a motor and the like, uncoiling is carried out manually, and the labor intensity of workers is high. In the prior art, the uncoiling can be carried out by using the driving of a motor, but the uncoiling area is separated from the surface milling area, so that a plurality of power sources are required for completing the uncoiling and surface milling processes of the metal strip, and the processing system has the defects of complex structure, high manufacturing cost, low productivity and the like. Meanwhile, most uncoiling areas can only be uncoiled in one direction, and metal strip blanks need to be processed on two sides, so that the production rate is low by adopting single-side milling.
