[0043] Wherein, the outside of side edge guide guard roller 10 is provided with arc-shaped outer guard plate 1001.

[0044] The working principle of the embodiment is:

[0045] The flattening process begins at the entry end of the steel plate, where the steel plate is guided into the leveling frame 2. The design of the leveling frame 2 is the core of the leveling machine, with the second fixed roller 6 mounted at the lower end and the adjustable second movable roller 7 at the upper end. The steel plate passes through the gap between the second fixed roller 6 and the second movable roller 7 under the drive of the servo motor 5, during which the flatness of the steel plate is preliminarily corrected. The precise control of the servo motor 5 ensures the stability of the steel plate transport and the continuity of the leveling.

[0046] Through the adjustment cylinder 8 at the upper end of the leveling frame 2, the piston rod is connected downward to the connecting roller seat 701, which in turn drives the second movable roller 7 to move up and down. This design allows users to flexibly adjust the position of the second movable roller 7 according to the thickness of the steel plate and the leveling requirements. The combination of the locking fixed block 702 on the connecting roller seat 701 and the scale rod 703 provides users with an intuitive adjustment reference, ensuring the accuracy of the adjustment. The scale rod 703 passes through the leveling frame 2, with the scale on it corresponding to the pointer on the leveling frame 2. Users can determine the current height of the second movable roller 7 by observing the position of the pointer.

[0047] When the second movable roller 7 is adjusted to the specified position, the locking motor 901 on the locking frame 9 is started, driving the lead screw 902 to rotate. The locking movable block 903 on the lead screw 902 moves downward along the movable strip hole 201 until the lower end of the inclined surface comes into contact with the inclined surface of the locking fixed block 702. This design not only fixes the position of the second movable roller 7, but also ensures the stability and reliability of the fixation. Even in high-intensity and long-time leveling operations, the position of the second movable roller 7 will not shift.

[0048] After the steel plate is preliminarily corrected by the leveling frame 2, it enters the smoothing guide frame 3 for further flattening. The design of the smoothing guide frame 3 also embodies the innovation of the utility model. The first fixed roller 301 is mounted at the lower end, and the first movable roller 302 is provided at the upper end. The first movable roller 302 is always subjected to a pushing force towards the first fixed roller 301 through the combination of the buffer rod 3021 and the buffer spring 3022. This design ensures that the steel plate can receive uniform and stable pressure when passing through the smoothing guide frame 3, thereby further improving the flatness of the steel plate.

[0049] In addition, the leveling frame 2 is provided with vertical side edge guide rollers 10 at both ends corresponding to the entry end of the steel plate, and arc-shaped outer guards 1001 are further provided outside. This design not only helps to guide the steel plate to enter the leveling frame 2 smoothly, but also effectively prevents the steel plate from shifting or being damaged during the leveling process.
