[0018] Put the hot-rolled plate on the placement table, and then push the hot-rolled plate to move, so that the hot-rolled plate moves between the active roller and the driven roller mechanism. Since the control frame drives multiple sets of driven roller mechanisms to tilt, and the inclined openings of the multiple sets of driven roller mechanisms are directed toward the placement table, the hot-rolled plate moves with the active roller, so that the distance between the active roller and the driven roller mechanism of the hot-rolled plate becomes smaller and smaller, and then the pressure on the hot-rolled plate gradually increases during the movement, so that the straightening effect of the hot-rolled plate becomes better and better.

[0040] Working principle: When in use, the worker first starts the hydraulic cylinder 618, so that the hydraulic cylinder 618 pulls the slide 66 to slide along the slide rail 65 through the linkage plate 617, so that the slide 66 drives the push plate 67 to move, and then the push plate 67 pushes the linkage rod 612 to move upward, and the linkage rod 612 drives the slide rod 69 to slide along the slide groove 68 through the docking frame 611 and the connecting piece 610, so that the linkage rod 612 is close to the surface of the push plate 67, and the control frame 613 is tilted with another set of linkage rods 612 as the axis, and at the same time the control frame 613 drives the adjustment frame 614 to move upward, and the adjustment frame 614 drives the control rod 616 to slide in the inner side of the support frame 615, so that the adjustment frame 614 pulls the support frame 615 to move upward through the control rod 616. The plurality of driven roller mechanisms 7 are moved upward, and the support frame 615 drives the sliding frame 62 to move upward, so that the plurality of driven roller mechanisms 7 move upward in sequence, and each group of driven roller mechanisms 7 moves upward by a different distance, so that the plurality of driven roller mechanisms 7 are tilted, and then the limit plate 631 is pulled upward, so that the limit plate 631 rotates around the rotating shaft 634, so that the limit plate 631 is adjusted to be tilted, and the limit plate 631 is made parallel to the plurality of driven roller mechanisms 7, and then the limit plate 631 is pushed to rotate toward the limiting seat 61, so that the limit plate 631 clamps the limit rod 633 in the control groove 632, and then the bolt 635 is passed through the limit plate 631 and screwed into the inside of the limiting seat 61, so that the limit plate 631 limits the driven roller mechanism through the limit rod 633. 7 moves up and down, and by starting the hydraulic cylinder 618, the slide 66 drives the push plate 67 to move, and the push plate 67 pushes the connecting rod 612 to move upward, so that the control frame 613 rotates with another set of connecting rods 612 as the axis, and the control frame 613 drives the support frame 615 to move upward through the adjustment frame 614, and the support frame 615 drives the driven roller mechanism 7 to move upward through the slide frame 62, so that the purpose of driving multiple sets of driven roller mechanisms 7 to move upward in sequence can be achieved, and the distance that each set of driven roller mechanisms 7 moves upward is different, so that the multiple sets of driven roller mechanisms 7 are tilted. Secondly, if the other two sets of hydraulic cylinders 618 are started, the control frame 613 is rotated in the opposite direction, so that the tilt openings of the multiple sets of driven roller mechanisms 7 are released. The change occurs, and then another set of limiting portions 63 is used to limit the up and down movement of the multiple sets of driven roller mechanisms 7, so that the multiple sets of driven roller mechanisms 7 can adapt to different use environments. At this time, the screws 714 are unscrewed, and the rotating ring 74 is rotated, so that the rotating ring 74 drives the sliding ring 73 to slide in the inner side of the connecting plate 72, and the rotating ring 74 drives the linkage block 710 to slide in the moving groove 77, so that the rotating ring 74 drives the regulating rod 76 to rotate through the linkage block 710, and the regulating rod 76 drives the protrusion 713 to rotate, so that the regulating rod 76 pushes the telescopic block 79 outward through the protrusion 713, so that the telescopic block 79 drives the contact piece 711 to expand outward, and at the same time, the multiple sets of contact pieces 711 stretch the spring sleeve 716, so that the multiple sets of contact pieces 711 always form a circle,At this time, screwing the screw 714 from the inside of the connecting plate 72 to the inside of the sliding ring 73 again can limit the rotation of the rotating ring 74, thereby limiting the rotation of the regulating rod 76, and limiting the contact piece 711, thereby changing the diameter of the circle formed between the multiple groups of contact pieces 711, thereby changing the spacing between the multiple groups of driven roller mechanisms 7, and changing the distance between the multiple groups of driven roller mechanisms 7 and the active roller 2. By rotating the rotating ring 74, the rotating ring 74 drives the regulating rod 76 to rotate through the linkage block 710, and the regulating rod 76 pushes the telescopic block 79 to move through the protrusion 713, so that the telescopic block 79 drives the contact piece 711 to expand outward, so as to achieve the purpose of facilitating the adjustment of the diameter of the circle formed between the multiple groups of contact pieces 711, thereby achieving the change of the spacing between the multiple groups of driven roller mechanisms 7. , and change the distance between multiple sets of driven roller mechanisms 7 and the active roller 2. At this time, start the motor 5 again, so that the motor 5 drives the gear transmission group 3 to operate through the transmission shaft 4, so that the gear transmission group 3 drives multiple sets of active rollers 2 to rotate. Then the worker puts the hot-rolled plate on the placement table 8, and then pushes the hot-rolled plate to move, so that the hot-rolled plate moves between the active roller 2 and the driven roller mechanism 7. Because the control frame 613 drives the multiple sets of driven roller mechanisms 7 to tilt, and makes the inclined openings of the multiple sets of driven roller mechanisms 7 face the placement table 8, when the hot-rolled plate follows the active roller 2 to move, the distance between the active roller 2 and the driven roller mechanism 7 on the hot-rolled plate becomes smaller and smaller, and then the pressure on the hot-rolled plate during the movement gradually increases, so that the straightening effect of the hot-rolled plate is getting better and better. ,
