A control center 5 is threadedly connected to the outer surface of the first screw 3. When the first motor 2 is started, the first screw 3 will be driven to rotate. The rotation of the first screw 3 will drive the control center 5 to move horizontally along the first screw 3. The setting of the first connecting rod 4 can support the control center 5 to prevent the control center 5 from rotating along with the rotation of the first screw 3.

[0024] See also Figure 3 , Figure 4 The outer surface of the control center 5 is fixedly connected to a support block 6, the inner wall of the support block 6 is slidably connected to a first connecting rod 4, both ends of the first connecting rod 4 are rotatably connected to the fixed frame 1, the outer surface of the first screw 3 is rotatably connected to the fixed frame 1, and the bottom surface of the control center 5 is fixedly connected to a connecting plate 7. The control center 5 will slide on the first connecting rod 4 through the support block 6, and the connecting plate 7 fixes the control center 5 and the connecting frame 8 together.

[0025] See also Figure 3 , Figure 4 The bottom surface of the connecting plate 7 is fixedly connected to a connecting frame 8, and the inner wall of the connecting frame 8 is rotatably connected to four second screws 9. The outer surface of each second screw 9 is threadedly connected to a push plate 10, and the outer surface of each push plate 10 is slidably connected to the connecting frame 8. The connecting frame 8 serves as a supporting mechanism for the push plate 10, and the PLC control of the four second screws 9 by the control center 5 makes the second screw 9 rotate, and the rotation of the second screw 9 drives the corresponding push plate 10 to move horizontally along the corresponding second screw 9, and the two opposite push plates 10 will move in opposite or reverse directions at the same time.

[0026] See also Figure 1 , Figure 2 The outer surface of the fixed frame 1 is rotatably connected to two support plates 13, and the sides of the two support plates 13 that are away from each other are fixedly connected to a fixed block 14, and the sides of the two support plates 13 that are close to each other are rotatably connected to the transmission belt 12. The support plates 13 can rotate around the fixed frame 1, and when the support plates 13 rotate, the transmission belt 12 can be driven to rotate, and the support plates 13 stop when they rotate to be horizontal with the conveying roller 19.

When the traction chain 16 is pulled, the material on the transmission belt 12 can be lifted. The traction chain 16 bypasses the pulley 17, and the direction of the traction chain 16 can be changed through the pulley 17.

[0029] The implementation principle of a feeding mechanism for a die-cutting machine in the embodiment of the present application is as follows: first, the chain drum 18 is controlled by the control panel 20 to extend the traction chain 16, at which time the traction chain 16 drives the support plate 13 to rotate around the fixed frame 1 until the support plate 13 contacts the ground, at which time the material is placed on the transmission belt 12, and then the chain drum 18 starts to operate and the traction chain 16 is retracted, at which time the traction chain 16 drives the support plate 13 to rotate around the fixed frame 1 through the connecting block 15 until the support plate 13 is horizontal, at which time the material is lifted and made horizontal, and then Start the second motor 11, the second motor 11 will drive the transmission belt 12 to operate, and drive the material onto the conveying roller 19. When the support plate 13 lifts the material, the material will enter the middle of the four push plates 10, and the four second screws 9 will rotate through PLC control, and the material will be clamped by the push plates 10. The first motor 2 will be started at the same time as the second motor 11, and the rotation of the first screw 3 driven by the first motor 2 will drive the control center 5 to push horizontally, until the material enters the conveying roller 19, the push plate 10 clamps the material and continues to transport and feed the material.
