[0021] A pushing plate 66 is provided to slide through the inside of the material storage frame 4 near the bottom, and a square plate 65 is fixedly connected to the end of the pushing plate 66 away from the conveyor belt 7. A rotating plate 62 is provided on the side of the square plate 65 away from the pushing plate 66. A cylinder 63 is fixedly connected at the center of the top end of the square plate 65 and at the eccentric point of the bottom end of the rotating plate 62. The two cylinders 63 are connected by a third connecting rod 64 rotatably arranged on the cylinder 63 at both ends; a second fixed sleeve 61 is fixedly connected to the side of the U-shaped frame 1 near the square plate 65, and a motor 6 is fixedly arranged in the second fixed sleeve 61, and the output end of the motor 6 is fixedly connected to the center of the top end of the rotating plate 62; the rotating plate 62 is driven to rotate by the motor 6, and when the rotating plate 62 rotates, it will drive the third connecting rod 64 rotatably arranged at the bottom to move, which will cause the square plate 65 and the material stripping plate to perform reciprocating linear motion, thereby achieving the effect of evenly controlling the discharge of materials and preventing blockage caused by excessive discharge of materials.

[0022] The top of the material storage frame 4 is fixedly connected with a trapezoidal frame 5, which can make material unloading more convenient.

[0023] The buckle device includes a connecting plate 31 fixedly connected to the top of the second connecting rod 3, two symmetrically distributed sliding grooves 32 are provided on the connecting plate 31, two symmetrically distributed clamping plates 33 are slidably connected to the connecting plate 31, a spring 34 is fixedly provided at the centers of the opposite sides of the two clamping plates 33, a clamping block 35 is provided between the two clamping plates 33, a support rod 36 is fixedly connected to the side of the clamping block 35 close to the U-shaped frame 1, the support rod 36 slides through the U-shaped frame 1, and two symmetrically distributed triangular blocks 12 are fixedly provided on the side of the compression plate 11 close to the U-shaped frame 1, and the triangular blocks 12 can squeeze the support rod 36; a rotating shaft 21 is rotatably passed through one side of the bottom plate 2 away from the second connecting rod 3, and both ends of the rotating shaft 21 are fixedly connected to the first connecting rod Rod 22, the first connecting rod 22 is fixedly connected to the U-shaped frame 1 at one end away from the rotating shaft 21; after the compression plate 11 is compressed into the U-shaped frame 1, when the triangular block 12 moves to the support rod 36, the support rod 36 will be pushed outward, so that the block 35 is pushed out, and the card plate 33 loses the support point, and cooperates with the rotating shaft 21 to make the bottom plate 2 flip over, so that the compressed waste is discharged, and then when the compression plate 11 retreats, the rotating shaft 21 is cooperated to make the entire bottom plate 2 slowly return to the level, and then the staff pushes the block 35 toward the U-shaped frame 1, so that the block 35 is stuck between the two card plates 33, thereby completing the compression and recovery of the waste, reducing the space occupied by the waste, and reducing the workload of the staff.

[0024] The top of the U-shaped frame 1 is located below the conveyor belt 7 and is fixedly connected with an inclined plate 16 , which can prevent waste from remaining on the surface of the conveyor belt 7 .

[0025] Working principle: When the die-cutting machine is working, the waste materials generated fall from the trapezoidal frame 5 into the material storage frame 4, and then the motor 6 is started to drive the rotating plate 62 to rotate. When the rotating plate 62 rotates, it will drive the third connecting rod 64 set at the bottom to move, which will make the square plate 65 and the material stripping plate move back and forth in a straight line, so as to achieve the effect of uniformly controlling the discharge of materials, prevent the blockage caused by excessive discharge of materials, and push the waste materials in the material storage frame 4 to the conveyor belt 7;

[0026] The waste is then transported to the U-shaped frame 1 through the conveyor belt 7. After the waste is transported, the cylinder 13 is started to push the compression plate 11 to compress the waste in the U-shaped frame 1. When the compression of the compression plate 11 is completed, the triangular block 12 on the compression plate 11 will push the support rod 36 outward, so that the card block 35 is pushed out, and the card plate 33 loses its support point. In conjunction with the rotating shaft 21, the bottom plate 2 is flipped, so that the compressed waste is discharged. Then, when the compression plate 11 retreats, the rotating shaft 21 is cooperated to make the entire bottom plate 2 slowly return to the horizontal level. Then the staff pushes the card block 35 toward the U-shaped frame 1, so that the card block 35 is stuck between the two card plates 33, thereby completing the compression and recovery of the waste, reducing the space occupied by the waste, and reducing the workload of the staff.

Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
