[0017] It should be particularly noted that when an element is described as "fixed to, fixedly connected to, connected to, or communicated with" another element, it can be directly fixed, fixedly connected, connected, or communicated to the other element, or indirectly fixed, fixedly connected, connected, or communicated to the other element through other intermediate connecting members.

[0018] Unless otherwise defined, all professional terms used hereinafter have the same meaning as commonly understood by those skilled in the art. The professional terms used herein are only for the purpose of describing specific embodiments and are not intended to limit the protection scope of the present utility model. Embodiment

[0019] As Figure 1 shown, a kind of extreme foil cutting device includes a base 1, a cutter group 2, a cutter group support 3 and side plates 4. Both ends of the cutter group 2 are connected to the base 1 through the cutter group support 3, and the side plates 4 are connected to the cutter group support 3. The base 1, the cutter group support 3 and the side plates 4 form a cutting space for the cutter group 2; a negative pressure dust removal component 5 is arranged on the side plates 4. The negative pressure dust removal component 5 includes a negative pressure pipe (not shown in the figure) and a dust suction member 51. The dust suction member 51 includes a connection end 511 and a dust suction end 512. The dust suction end 512 is arranged inside the cutting space, the dust suction port of the dust suction end 512 faces the cutter group 2, and the connection end 511 passes through the side plate 4 and is connected to the negative pressure pipe. In this embodiment, as Figure 3 shown, the dust suction end 512 is in a horn shape; the dust suction port of the dust suction end 512 is arranged opposite to the cutting knife of the cutter group 2, and the dust suction port is arranged as a strip-shaped, round-hole-shaped or V-shaped diversion port; so that the dust thrown off from the cutting knife can be sucked away in time. In this embodiment, the dust suction end can also be V-shaped or U-shaped.

[0020] In this embodiment, there are two side plates 4 and they are arranged oppositely; negative pressure dust removal components 5 are arranged on the oppositely arranged side plates 4, and the dust suction member 51 of each negative pressure dust removal component 5 faces a cutting roller of the cutter group 2; the cutting roller of this embodiment can adopt the guiding die disclosed in Patent CN 117584189 A, a capacitor positive and negative material and battery positive and negative sheet material cutting device and its method.

[0021] As Figure 1 and Figure 3 shown, a felt 62 brush assembly 6 is arranged on the side plate 4 above the dust suction member 51. The felt 62 brush assembly 6 includes a clamp 61, a felt 62 and a joint 63. One end of the joint 63 is connected to the felt 62 on the clamp 61 and the other end is connected to an alcohol infusion pipe; a through groove for accommodating the clamp 61 is arranged on the side plate 4. After the clamp 61 is arranged in the through groove, the felt 62 on the clamp 61 contacts the cutting knife of the cutter group 2.
