The utility model forms a rotating structure through the motor, shaft and second gear disc, the second gear disc is meshingly connected with the first gear disc, the first gear disc drives the first rotating wheel to rotate, and the outside of the first rotating wheel is fixedly connected with an extrusion block, which solves the problem that the straightened cold-rolled strip cannot be transported. The cold-rolled strip is pushed by the extrusion block installed on the outer wall of the first rotating wheel, and the processed cold-rolled strip is conveniently transported, thereby achieving the purpose of improving the working effect, accelerating the work process, and improving the overall speed.

[0004] Excessive straightening force may cause irreversible microstructural damage inside the strip, affecting the mechanical properties of the material, while insufficient straightening cannot completely solve the plate shape problem. With the advancement of science and technology, modern straightening structures have adopted more scientific mechanical design and intelligent control technology, and existing devices cannot adjust the thickness of different cold-rolled strips. Therefore, it is necessary to propose a straightening structure for the production of low stamping debris cold-rolled strip. Utility Model Content
