[0028] In the embodiment of the utility model, the start of the electric push rod 17 can drive the die-cutting blade 6 to descend. When the die-cutting blade 6 is in contact with the paper package, the die-cutting blade 6 and the extrusion plate 4 continue to descend, and the die-cutting blade 6 can die-cut the paper package.

[0029] Embodiment 2:

[0030] Please refer to Figure 1-4 The servo motor 9 and the bidirectional screw 10 are fixedly connected by a coupling, the mounting seat 7 is provided with two groups and are symmetrically distributed, the mounting plate 8 is provided with two groups and are symmetrically distributed, the servo motor 9 is provided with two groups and are symmetrically distributed, and the bidirectional screw 10 is provided with two groups and are symmetrically distributed. A limit rod 12 is fixedly connected between the mounting seat 7 and the mounting plate 8, and the limit rod 12 is inserted into the inner cavity of the moving block 11, and the limit rod 12 is provided with multiple groups of linear distribution. The top of the moving block 11 is hinged with a rotating plate 13, and the top of the rotating plate 13 is hinged with a sliding plate 14. The top of the sliding plate 14 is installed with a lifting plate 15, and the sliding plate 14 and the lifting plate 15 are slidably connected.

[0031] A support frame 16 is fixedly connected to the top of the lifting plate 15, an electric push rod 17 is fixedly connected to the inner cavity of the support frame 16, the electric push rod 17 is fixedly connected to the working plate 2, a second telescopic rod 18 is fixedly connected between the support frame 16 and the working plate 2, and the second telescopic rod 18 is provided with a plurality of groups of rectangular array distributions.

[0032] In the embodiment of the utility model, the servo motor 9 is started, and the servo motor 9 drives the bidirectional screw 10 to rotate, and drives the moving blocks 11 to move closer to or away from each other. Since the rotating plate 13 is hinged at the top of the moving block 11, the rotating plate 13 will fold with each other as the moving blocks 11 approach each other, and drive the sliding plate 14 to move and rise.

[0033] During use, in order to be able to cooperate with staff members of different heights, the servo motor 9 is started at this time, and the servo motor 9 drives the bidirectional screw rod 10 to rotate, and drives the moving blocks 11 to move closer or farther away from each other.

Since the bottom of the working plate 2 is fixedly connected with the die-cutting blade 6, the start of the electric push rod 17 can drive the die-cutting blade 6 to descend. When the die-cutting blade 6 is in contact with the paper package, the die-cutting blade 6 and the extrusion plate 4 continue to descend, and the die-cutting blade 6 can die-cut the paper package, while the first telescopic rod 3 and the extrusion spring 5 are squeezed by the paper package. When the die-cutting is completed, the die-cutting blade 6 and the extrusion plate 4 move up, and the squeezed first telescopic rod 3 and the extrusion spring 5 will provide a reverse force to push the extrusion plate 4 downward. In the process of the die-cutting blade 6 moving up, the die-cutting blade 6 close to the paper package can separate the paper package from the die-cutting blade 6 to avoid the adhesion of the die-cutting blade 6 to the paper package.
