[0002] Stainless steel sheet, as an important industrial raw material, is widely used in automobiles, home appliances, construction, aerospace, and other fields. During its processing, residual stress, warping, or waviness caused by rolling, stamping, or heat treatment processes often require straightening to restore its flatness. However, traditional stainless steel sheet straightening devices mostly rely on manual loading and unloading, requiring operators to frequently move and adjust the position of the sheets. This is labor-intensive, inefficient, and difficult to match the needs of high-speed continuous production lines, resulting in unsatisfactory straightening effects. Utility Model Content

The second upper straightening roller 901 and the second lower straightening roller 701 are designed with a small roller gap and low pressure. The second motor screw assembly 908 drives the second lifting connecting block 907, which in turn drives the second support frame 902 and the second upper straightening roller 901 downwards to further straighten the plate and correct local unevenness. Each second upper straightening roller 901 is driven by an independent second drive motor 905 and can rotate in both directions, making it an active roller that can drive the plate conveying.

[0040] Next, the stainless steel plate a is fed between the two rear conveyor rollers 501, as follows: Figure 7 , Figure 8 The rear drive cylinders 503 on both sides drive the rear bracket 502 to extend the rear conveyor roller 501. The two rear conveyor rollers 501 are used to position the input plate. Then, the two rear drive motors 504 drive the two rear conveyor rollers 501 to rotate, and use friction to convey the plate.

[0041] When the sheet material is output, the surface flatness is tested by the flatness tester 11 to ensure product quality. Finally, the unloading robot arm 3 grabs the sheet material and uses a vacuum suction cup to stably adsorb the sheet material for transportation and output.
