[0061] The working principle and use process of the present application are as follows: first, the driving motor 624 drives the movable rod 713 to rotate, and through the cooperation of the worm 715 and the worm wheel 710, a transmission assembly is formed to transmit power and drive the conveying roller 5 in the conveying frame 4 to rotate, facilitating the conveying of the metal plate, so that the metal plate enters the finishing box 2 through the fixed frame 701, and at the same time, in the process of the metal plate passing through the fixed frame 701, the transmission rod 720 is driven to rotate through the cooperation of the bevel gear 722, and then the vertical rod 717 and the width regulating roller 718 are driven to rotate synchronously through the transmission belt 721, so that the width of the metal plate is adjusted during the conveying of the metal plate, and the metal plate is prevented from deviating during conveying, facilitating subsequent rolling;

[0062] When the metal plate does not enter the finishing box 2 and derails, the metal plate is accumulated in the fixed frame 701, the compression roller 704 and the concave plate 703 are pushed up, the concave plate 703 pushes the sliding rod 702 and the top plate 705 up, the top plate 705 contacts the touch switch 709 at the bottom end of the mounting frame 707, so that the electric push rod 711 is started, the electric push rod 711 pushes the frame 712 up, the meshing of the worm 715 and the worm wheel 710 at the top end in the frame 712 is released, the meshing of the worm 715 and the worm wheel 710 at the bottom end in the frame 712 is engaged, the rotating direction of the conveying roller 5 is changed, the metal plate is forced to move out of the fixed frame 701, the accumulation of the metal plate in the fixed frame 701 is prevented, and subsequent processing is facilitated;

[0063] Then, through the cooperation of the rotating motor 821 and the inner cross splicing cylinder 822, the cross rod 814 is rotated, so that the cross rod 814 drives the load roller 815 to rotate, and at the same time, the piston rod 807 is pushed down by the hydraulic cylinder 806, so that the top frame 808 drives the load roller 815 to descend, the distance between the two rollers 820 is adjusted, the passing metal plate is rolled by the rollers 820, the thickness of the metal plate is reduced, and the length of the metal plate is increased;

[0064] Then, after the metal plate is rolled, it passes through the guide frame 3, and the driving motor 624 is started to rotate the connecting rod 622, and the power is transmitted by the track 623 to rotate the six-rib rod 609 together with the two connecting rods 622, forcing the six-rib rod 609 to rotate with the inner hexagonal sleeve 610 and the half-tooth ring 611, and then through the cooperation of the tooth protrusion 617, forcing the half-tooth ring 611 to slide along the inner wall of the vertical plate 613 left and right, and further transmitting power through the cooperation of the tooth plate 618 to drive the driven gear 620 and the rotating rod 619 to rotate, so that the rotating rod 619 drives the traction disc 603 to rotate left and right, and then pushes the push plate 604, so that the push plate 604 drives the limiting hammer head 608 to move on the guide frame 3, and the width of the metal plate is adjusted, the deformation size of the metal plate in the width direction after rolling is reduced, and the rolling effect of the subsequent metal plate is ensured.
