A pressing rod 20 is snap-connected to the top of the positioning bracket 21 through a snap groove. One end of the pressing rod 20 is fixedly connected to an electric telescopic frame 7. The other end of the electric telescopic frame 7 is fixedly connected to the top of the pressing plate 5 through an articulation hinge. Through the positioning bracket 21 fixed to the top of the pressing plate 5, the pressing rod 20 can be limited, so as to avoid the situation that the electric telescopic frame 7 is displaced excessively due to the pressing rod 20 being pressed down too much, which affects the cutting effect. At the same time, it is also convenient to toggle the pressing rod 20 to separately lift one end of the electric telescopic frame 7 to perform maintenance and replacement operations on the slitting knife plate 8 at the bottom of the electric telescopic frame 7, which facilitates the maintenance of the entire device.

[0041] As Figure 4 As shown, one end of the telescopic rod at the bottom of the electric telescopic frame 7 is fixedly connected to a slitting knife plate 8. The slitting knife plate 8 is located inside the knife groove 24 and is directly above the reflective strip 17. By pushing the slitting knife plate 8 to move through the electric telescopic frame 7, the slitting knife plate 8 is brought close to the cutting support plate 16, so as to cooperate with the cutting support plate 16 to perform extrusion cutting on the explosion-proof film.

[0042] As Figure 5 As shown, a pair of limiting convex blocks 19 are fixedly connected to the top surface of the bearing plate 1. The pair of limiting convex blocks 19 are respectively located at both ends of the cutting support plate 16.

[0044] As Figure 1 and Figure 5 shown, on the other side of the bearing plate 1, a second extension bracket 10 is fixedly connected. Inside the second extension bracket 10, a winding roller 12 is movably connected through a bearing. One end of the winding roller 12 is fixedly connected to a rocker 13. An outer wall of the winding roller 12 is sleeved with a rubber cylinder 22. Vacuum hole grooves 23 are formed on an outer wall of the rubber cylinder 22. The winding roller 12 is a hollow tube. A sealing plug 14 is rotatably installed at the other end of the winding roller 12. An air vent hole is formed between an inside of the winding roller 12 and an inside of the vacuum hole grooves 23. By rotating the rocker 13 fixedly connected to one end of the winding roller 12, the winding roller 12 can be driven to rotate, so as to wind the explosion-proof film by using the rubber cylinder 22 on the outer wall of the winding roller 12 and wind up the cut explosion-proof film. The vacuum hole grooves 23 formed on the outer wall of the rubber cylinder 22 can be used to generate a vacuum pressure to adsorb and fix the explosion-proof film, preventing the explosion-proof film from being easily detached. At the same time, by removing the sealing plug 14 rotatably installed at the other end of the winding roller 12 to ventilate the vacuum hole grooves 23, the vacuum state can be released, facilitating the removal of the explosion-proof film wrapped around the outer wall of the rubber cylinder 22.

[0045] As Figure 1 and Figure 2 shown, the pressing plate 5 is made of a transparent acrylic plate. A knife groove 24 is fixedly connected to a bottom end of the bearing plate 1, and the bearing plate 1 is made of a colored resin plate. A latex plate 25 is fixedly connected to the bottom end of the bearing plate 1. By using the pressing plate 5 made of the transparent acrylic plate, the production cost of the device is reduced, and at the same time, it is convenient for a user to observe the cutting position of the explosion-proof film through the pressing plate 5, so as to timely understand the cutting progress and accuracy of the explosion-proof film. The bearing plate 1 made of the colored resin plate can form a color difference contrast with the explosion-proof film, so as to facilitate the user to understand the position of the explosion-proof film. By the latex plate 25 fixedly connected to the bottom end of the bearing plate 1, the stability and anti-slip property of the whole device during placement and use can be improved.

[0046] As Figure 4 shown, the slitting knife plate 8 is a slitting knife plate with stripping rubber plates wrapped on both sides. The slitting knife plate 8 with stripping rubber plates wrapped on both sides can prevent the cutting edge from jamming materials.

[0047] The working principle provided by the present utility model is as follows: Insert the winding cylinder of the explosion-proof film to be cut into the outer wall of the positioning roller 11 movably connected through a bearing inside the first extension bracket 9, then pull the explosion-proof film to lay the explosion-proof film flat between a pair of limit bumps 19 on the top end of the bearing plate 1. After confirming the cutting position, press down the pressing plate 5 to clamp and fix the explosion-proof film by using the pressing plate 5 in cooperation with the bearing plate 1. Then, toggle the pressing rod 20 to position the electric telescopic frame 7, and push the slitting knife plate 8 close to the cutting support plate 16 through the electric telescopic frame 7, so as to squeeze and cut the explosion-proof film in cooperation with the cutting support plate 16.

[0048] During the use of the device, the limit bumps 19 located at both ends of the cutting pallet 16 can limit the explosion-proof film, thus avoiding the situation that the explosion-proof film shifts sideways and affects the cutting effect. By rotating the rocker 13 fixedly connected to one end of the winding roller 12, the winding roller 12 can be driven to rotate, so as to wind the explosion-proof film by the rubber cylinder 22 on the outer wall of the winding roller 12 and wind up the cut explosion-proof film. The vacuum hole grooves 23 formed on the outer wall of the rubber cylinder 22 can be used to generate vacuum pressure to adsorb and fix the explosion-proof film, preventing the explosion-proof film from being easily detached. At the same time, by removing the sealing plug 14 rotatably installed at the other end of the winding roller 12 to ventilate the vacuum hole grooves 23, the vacuum state can be released, which is convenient for removing the explosion-proof film wrapped around the outer wall of the rubber cylinder 22. The pressing plate 5 made of transparent acrylic plate reduces the production cost of the device. At the same time, it is convenient for users to observe the cutting position of the explosion-proof film through the pressing plate 5, so as to timely understand the cutting progress and accuracy of the explosion-proof film. The bearing plate 1 made of colored resin plate can form a color difference contrast with the explosion-proof film, so as to facilitate users to understand the position of the explosion-proof film. The latex plate 25 fixedly connected to the bottom end of the bearing plate 1 can improve the stability and anti-slip performance of the whole device when it is placed and used. The slitting knife plate 8 wrapped with stripping rubber plates on both sides can avoid the situation of material jamming on the cutting edge.
