A fixing block 604 is fixedly connected to the side of the rotating block 602 away from the connecting block 601. Second springs 603 are fixedly connected to both the upper and lower ends of the fixing block 604. One end of the second spring 603 away from the fixing block 604 is fixedly connected to a clamping plate 605. The clamping plate 605 is rotatably connected to the rotating block 602. Open the clamping plate 605 and place both ends of the sheet into the symmetrical clamping plates 605. The anti-slip pad 7 applies pressure to the sheet to prevent it from slipping out. The second spring 603 applies a pulling force to clamp the sheet by the clamping plate 605.

[0025] The feeding mechanism 2 includes a fixing frame 201. The fixing frame 201 is fixedly connected to the front side of the top of the workbench 101. A motor 202 is fixedly connected to the front end of one side of the fixing frame 201. The output shaft of the motor 202 is connected to a conveyor belt 203.

The anti-slip pads 7 exert pressure on the plate to prevent it from slipping out. The second spring 603 exerts a pulling force to clamp the plate with the clamping plates 605. Subsequently, the cylinder 301 drives the movable plate 302 to descend, causing the pressing plate 304 to press down on the plate. The two ends of the plate are upturned due to bending, causing the rotating block 602 to rotate within the connecting block 601, pushing the sliding block 501 to slide within the sliding groove 104, and avoiding the movement of the plate due to deformation during the bending process.
