[0026] It can be seen from the above technical scheme that when in use, first, the steel plate to be leveled is placed on the feeding plate 14 by a forklift, and the lifting plate 13 is driven by the first driving mechanism 2 to raise the steel plate to a higher position, so that the height of the steel plate is consistent with the height of the steel plate to be leveled, so that the steel plate can be horizontally fed between the upper pressing roller and the lower pressing roller to prevent the steel plate from not being able to smoothly enter between the upper pressing roller and the lower pressing roller due to the inconsistent height of the steel plate and the rolling, causing material obstruction, and then, the feeding plate 14 is driven by the second driving mechanism 3 to move in a horizontal direction to guide the steel plate to be uniformly transported in a horizontal direction to the front feeder The steel plate surface can be rolled evenly at a constant speed by the feeding mechanism 6, and the steel plate can be quickly directional and flattened in the horizontal direction by the pressing roller structure 4. The rolled steel plate is continuously conveyed to the support plate 16 by the rear feeding mechanism 6, and the flatness of the leveled steel plate is detected by the detection mechanism 5, which increases the flatness leveling efficiency of the steel plate. The detection mechanism 5 is convenient for quickly detecting the flatness of the steel plate, and the uneven position of the steel plate can be quickly detected, with high detection efficiency and fast detection speed. The detection principle of the detection mechanism 5 includes: first, First, the DCS controller controls the second motor 57 to rotate the driving gear 56. According to the lateral width of the steel plate, the driving gear 56 meshes with the two racks 55 to drive the two racks 55 to move in opposite directions, so that the lifting rods 52 on the racks 55 can be pressed against the surface of the steel plate through the universal ball 553. When the steel plate moves in the longitudinal direction, the larger protrusions on the steel plate will cause the lifting rod 52 to move upward. When the lifting rod 52 moves upward, the lifting rod 52 will drive the compression spring 554 upward to press the elastic plate 557 upward. The elastic plate 557 pushes upward against the pressure sensor 556, and the detection end at the bottom of the force sensor 556 detects a signal that the spring elastic force increases. The force sensor 556 feeds back the force change signal to the control system in real time. The control system alarms and immediately stops leveling. Then the operator controls the control valve of the paint spray gun 58 through the controller button of the paint spray gun 58, so that the paint spray gun 58 automatically sprays paint liquid to the raised parts of the steel plate detected by the force sensor 556 to mark them, so as to facilitate timely detection and timely marking, and timely secondary leveling treatment of unqualified steel plates.
