The bottom of the connecting column 334 is connected to the driven roller 335, driving the driven roller 335 to lift in height, thereby adjusting the distance from the conveying roller 32.

[0037] Working principle: When the steel art door needs to level the steel coil plate during the production process, by driving the piston rod of the telescopic cylinder 13 to expand and contract, driving the connected connecting rod 151 and the end seat 152 connected to the connecting rod 151 to expand and contract synchronously, the left and right movement of the end seat 152 can be used to drive the cross telescopic frame 153 to expand and contract up and down until the steel coil can be placed on the expansion mechanism 15. Then, by pulling the steel coil plate on the steel coil to the feeder 2, through the conveying of the feeder 2, the steel coil can be conveyed to the flattening mechanism 3 for leveling;

[0038] When the rotating handle 332 drives the threaded column 333 to rotate and descend, the threaded column 333 will engage and rotate on the connecting column 334 and drive the connecting column 334 to move up and down. The bottom of the connecting column 334 is connected to the driven roller 335, which will drive the driven roller 335 to move up and down in height, thereby adjusting the distance from the conveying roller 32, and enabling flattening of steel coil plates of different thicknesses. At the same time, through the forward and reverse rotation of the output end of the drive motor group 348, the rotating plate 347 connected thereto will be driven to rotate synchronously, thereby driving the push rods 346 at both ends of the rotating plate 347 to push inwards or outwards, driving the bottom plate 344 connected to the other end of the push rod 346 and the limiting plates 345 located on the bottom plate 344 to move towards or away from each other, adjusting the distance between the two limiting plates 345, so that the centering mechanism 34 can limit the position of the steel coil and prevent the steel coil from running off during flattening.
