[0026] Specifically, in actual use of this case, the electric push rod 5 is used to move the bottom adjustment component 2 to the appropriate position, and the cutting plate 203 at the edge is moved to slide on the first slide bar 202, and the adjustment rod 205 on the cutting plate 203 rotates, driving the cutting plate 203 connected thereto to move. Because a fixed block 204 is fixed in the middle of the fixed plate 201, and the adjustment rod 205 fixed on the cutting plate 203 adjacent to the fixed block 204 is rotatably connected to the fixed block 204, the cutting plate 203 is symmetrically adjusted along the fixed block 204 on the fixed plate 201 during movement. After adjusting to the appropriate position, the protective film is passed through and transported between the two material transport roller groups 1011 to achieve the effect of automatic material transport and cutting. The component can quickly adjust the spacing between the cutting plates 203 to meet the slitting requirements of protective films of different sizes.

[0027] Combination Figure 4-Figure 5 The cutting knife 2032 is fixed to the bottom of the cutting plate 203 by bolts. The cutting knife 2032 is fixed to the bottom of the cutting plate 203 by bolts. When the cutting knife 2032 needs to be replaced or maintained, it can be partially disassembled without disassembling the entire device, which is convenient for replacement and maintenance, saving maintenance time and efficiency.

[0028] Rubber pads 2031 are fixed on both sides of the cutting plate 203 and the fixing block 204. The rubber pads 2031 are fixed on both sides of the cutting plate 203 and the fixing block 204, which can effectively prevent collisions during movement and damage to the components, thereby protecting the components and extending the service life of the components.

[0029] A measuring block 2033 is fixed on one side of the cutting plate 203, and a ruler 206 is fixed between the two fixed plates 201.
