[0038] Furthermore, according to some embodiments of the present invention, the pressure roller 640 is made of plastic material, and a rubber layer is provided on the surface of the pressure roller 640.

[0039] Understandably, the pressure roller 640, made of plastic, has a rubber layer on its surface, which provides sufficient friction to ensure the stability of the label paper 800 without damaging the label material, making it suitable for label papers 800 made of various materials.

[0040] Furthermore, refer to Figure 1 and Figure 2 According to some embodiments of the present invention, the cutting structure 700 includes a first electric push rod 710 and a cutting blade 720. The first electric push rod 710 is mounted on the side of the frame 510 and located behind the mounting base 610. The first electric push rod 710 is connected to the cutting blade 720 and can drive the cutting blade 720 to move up and down.

[0044] It can be understood that, by moving the die cutter 310 and the stripper 320 downward, the die cutter 310 is used to die cut the label paper 800, and then the pressing part 322 is used to press the die cut label product downward to press the label product on the workbench 100, so as to realize the separation of the label product and the waste.

[0045] It should be noted that, according to different label products in actual production, the cross-sectional shape of the die cutter 310 is also different, and the cross-sectional shape of the pressing part 322 is adapted to the cross-sectional shape of the die cutter 310, so as to ensure that the label product can be pressed completely, which is helpful for the separation of the label product and the waste. For example, when the label product is circular, the pressing part 322 can be designed as a sphere. Since the pressing part 322 has elasticity, when the pressing part 322 moves downward to contact the label paper 800 on the workbench 100, the pressing part 322 deforms and gradually shrinks into the die cutter 310. When the die cutting is completed and the die cutter 310 moves upward, the pressing part 322 continuously presses the die cut label product to separate it from the waste. At the same time, through the deformation of the spherical pressing part 322, the contact area between the pressing part 322 and the circular label product is increased, and the connecting edges of the label product and the waste are uniformly stressed, which improves the separation efficiency and prevents the uneven stress from causing cracks. The rest is the same, and will not be repeated here.

[0046] It should be noted that the elastic material of the stripper 320 can be rubber, silicone, etc., but is not limited thereto.
