[0021] refer to Figures 2 to 4 A slide groove 11 is provided on the inner surface of the body 1, and a second motor 12 is fixedly connected to the left side of the body 1. The output end of the second motor 12 passes through the interior of the slide groove 11 and is fixedly connected to a bidirectional screw 13. Both ends of the surface of the bidirectional screw 13 are threadedly connected to sliders 14. A slot cover 15 is fixedly connected to the top of the slide groove 11, and a correction plate 16 is fixedly connected to the top of the slider 14. The correction plate 16 is slidably connected to the slot cover 15.

[0022] As a technical optimization scheme of the utility model, through the setting of the correction plate 16, the bidirectional screw 13 is rotated by starting the second motor 12, and the rotation of the bidirectional screw 13 drives the sliders 14 on both sides of its surface to move relative to each other, so that the correction plate 16 moves relatively to limit the horizontal correction of the plate, thereby avoiding the tilt of the plate when moving, which greatly affects the processing accuracy.

[0023] refer to Figure 1 , Figure 2 and Figure 4 Both sides of the top of the lifting frame 7 are fixedly connected with sliding columns 17, the top of the sliding column 17 penetrates the top of the body 1 and is fixedly connected to the limited position support 18, and the sliding column 17 is slidably connected to the body 1.

[0025] refer to Figure 1 , Figure 2 and Figure 4 , the center lines of the top roller 3 and the pressure roller 10 are at the same level.

[0026] As a technical optimization solution of the utility model, by arranging the center lines of the top roller 3 and the pressure roller 10 at the same level, the horizontal misalignment of the center lines of the top roller 3 and the pressure roller 10 and the problem of tilted discharge after plate correction are avoided.

[0030] As a technical optimization solution of the utility model, the curved edge is provided so that the plate can slide along the curved edge of the correction plate 16 and be automatically corrected, thereby avoiding the problem of the plate colliding with the front end of the correction plate 16 and causing material jamming.

[0031] The working principle and use process of the utility model: when in use, when the user needs to correct the plate, the plate is placed on the top of the top roller 3, and the hydraulic rod 5 is started to drive the lifting frame 7 to descend. The descent of the lifting frame 7 drives the pressure roller 10 to fit the surface of the plate, and the first motor 9 is started. The first motor 9 drives the pressure roller 10 to rotate. The rotation of the pressure roller 10 drives the top roller 3 and the plate to move at a uniform speed. The pressure roller 10 corrects the deformation of the plate by rotating with the top roller 3 to squeeze the plate, and then the second motor 12 is started to rotate the bidirectional screw 13. The rotation of the bidirectional screw 13 drives the sliders 14 on both sides of its surface to move relative to each other, so that the correction plate 16 moves relative to limit the horizontal correction of the plate, and finally the plate enters the processing port 19 for processing.
