The friction push rod will rub against the outer surfaces of the rotating rollers on both sides during the rotation process, so that the rotating rollers on both sides will rotate under the action of friction resistance, thereby realizing the plate rolling of the device, and then one motor can drive the entire device to work, making the operation simple, reducing the workload of the staff, and preventing the waste of resources. At the same time, the rotation of the rotating rollers on both sides can promote the flipping of the plate during the rolling process. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] Working principle: When it is necessary to roll the plate, the staff can place the plate between the rotating rollers 21 and start the motor 3. When the motor 3 is started, it will drive the rotation of the middle rotating roller 21. When the middle rotating roller 21 rotates, it will drive the friction push rod 24 to rotate, and then the middle rotating roller 21 will drive the friction push rod 24 to rotate when it rotates.

[0025] When the friction push rod 24 rotates to the longitudinal position of the rotating roller 21, it will cause lateral knocking on the straight rod 42. Under the action of the knocking force, the straight rod 42 will swing left and right under the action of the arc-shaped elastic rod 44, and then the clamping rod 51 will cause the arc-shaped auxiliary plate 6 to clamp the plate from the bottom side under the action of the semi-arc rotating rod 5, thereby enhancing the anti-rebound effect of the plate. Secondly, by arranging a friction auxiliary plate 7 on the left arc-shaped auxiliary plate 6, when the friction auxiliary plate 7 contacts the outer surface of the plate, there is an intermittent lateral pushing force on the plate. Under the action of the lateral pushing, the plate is promoted to flip during the rolling process, thereby promoting the device to quickly roll the plate.
