It should be noted that the high frequency centrifugal paper cutter of the present utility model cuts a large thickness of paper, and the paper is suitably 200 g to 1000 g.

According to the utility model, the high-frequency vibration motor can enable the cutter 5 to vibrate and slot at the same time, so that the effect similar to that of saw cutting is achieved, the resistance of paper to the blade during slotting is smaller, the damage to the blade is effectively reduced, and the paper is prevented from being broken due to overlarge resistance between the paper and the blade at the slotting position.

In an embodiment, as shown in fig. 1 and 2, the high-frequency vibration device 2 further includes a housing 7, one end of the housing 7 is provided with a U-shaped groove, and the other end of the housing 7 is provided with a connecting piece 8, and the U-shaped groove is slidably connected with the fixing rod 1 through the resonant spring 4. It will be appreciated that the housing 7 can vibrate along the depth direction of the U-shaped groove (or the axial direction of the resonant spring 4) under the action of the resonant spring 4, and it should be noted that the fixing rod 1 is in an "L" shape, one end of the fixing rod 1 is fixed to the U-shaped groove, and the housing 7 cannot vibrate along the axial direction of the fixing rod 1 under the limitation of the U-shaped groove.

Further, as shown in fig. 1 and 2, the fixing rod 1 is provided with a through hole 9, the U-shaped groove is provided with a fixing hole 10, one end of the resonant spring 4 is fixed with the fixing hole 10, the other end of the resonant spring 4 is fixed with the through hole 9, the through hole 9 is provided with an elastic adjusting bolt 21, and the elastic adjusting bolt 21 can adjust the vibration frequency of the resonant spring 4, so that the best paper cutting effect is achieved. By the fact that the resonant spring 4 connects the housing 7 and the fixing rod 1 together, it should be noted that the housing 7 can vibrate slightly along the length direction of the U-shaped groove, in addition to vibrating along the depth direction of the U-shaped groove, because: when the resonant spring 4, the fixing rod 1 and the shell 7 are assembled, due to a certain size difference between the fixing hole 10 and the through hole 9 and the resonant spring 4, a gap exists between the resonant spring 4 and the fixing hole 10 or the through hole 9, so that the resonant spring 4 can be aligned relative to the fixing hole 10 and the through hole 9, and due to the fact that the shell 7 is limited by the U-shaped groove to vibrate along the axial direction of the fixing rod 1, the shell 7 can vibrate along the length direction of the U-shaped groove.
