The turning part of the M-type cutting edge adopts a small arc transition. The roller cutter shaft 21, cutting edge steps 22 and roller cutter mounting shaft 23 are integrally machined.

[0016] The adjusting mechanism 4 is used to adjust the downward stroke of the double M-shaped roller 2, thereby adjusting the cutting pressure of the double M-shaped roller 2 on the plaster backing paper. In this invention, the double M-shaped roller 2 and the bottom roller 3 rotate together through the friction of the materials.

[0017] Specifically, such as Figure 4 As shown, the upper part of the side plate 12 of the frame 1 has a square opening 14, and rails 15 are symmetrically arranged on both sides of the square opening 14; a connecting hole is opened on the side plate 12 below the square opening 14, and a bottom roller bearing 16 is installed in the connecting hole; a step is provided in the connecting hole to prevent the bottom roller from coming off the outside of the frame. The bottom roller 3 consists of a bottom roller shaft 31 and mounting shafts 32 set at both ends of the bottom roller shaft 31. The bottom roller 3 is connected to the frame 1 through two bottom roller bearings 16; the bottom roller shaft 31 and the mounting shaft 32 are integrally machined, as shown. Figure 6 As shown.

The slider 43 has sliding grooves 47 on both sides that cooperate with the rail 15 on the side plate 12. Under the action of the cylinder, the slider 43 can slide up and down along the rail 15. The slider 43 has mounting holes 48 for mounting the double M-type roller cutter 2. The double M-type roller cutter 2 is set in the frame 1 through the mounting holes 48 on the two sliders 43. A compressed air pipe 49 is connected to the cylinder 42.

[0019] The cylinder stroke adjuster is used to adjust the stroke length of the cylinder stroke rod, thereby adjusting the cutting force of the double M-type roller cutter; the cylinder stroke rod fixing nut is used to fix the cylinder stroke adjuster to prevent it from shifting during the operation of the die-cutting device; the cylinder stroke protective cap is used to protect the top of the cylinder stroke rod; the movement of the cylinder stroke rod is controlled by the cylinder, which is powered by compressed air supplied by the compressed air pipe.

[0020] The design has been further optimized by adding an annular step inside the mounting hole 48 to prevent the double M-type roller cutter bearing from coming off the outside of the frame and to avoid displacement of the double M-type roller cutter.

[0021] After adopting the die-cutting device with double M-type roller cutters of this utility model, the plaster backing paper is cut into three parts: left, right, and center. Figure 7 As shown. When using, first peel off the middle part of the backing paper, then stick the plaster to the patient's affected area, and finally peel off the left and right parts of the backing paper to avoid the plaster sticking together and wrinkling when sticking it on after peeling off the backing paper.
