[0034] It should be noted that a guide groove 111 is provided on the inner wall of the slitter body 110, and the end of the sliding frame 170 is slidably arranged in the guide groove 111.

[0035] In a specific implementation scheme, support feet 114 are provided at the bottom of the slitter body 110.

[0036] Please refer to Figure 1 、 3 As shown in FIGS. 4 and 5, the cutting mechanism 200 includes a secondary cutting knife 210 and a main cutting knife 220. The secondary cutting knife 210 is fixedly connected to the slitter body 110, and the main cutting knife 220 is fixedly connected to the sliding frame 170 and the cutting edge is inclined.
