[0051] The driving mechanism is installed on the fixing frame 1 and is used to control the two dust removal brushes 2 to move closer to or farther from each other along the X direction.

[0052] In the present technical solution, the pole roll after cutting is placed on the supporting mechanism, and the driving mechanism controls the two dust removal brushes 2 to approach the pole roll. After the bristles 13 of the dust removal brush 2 are in contact with the axial sides of the pole roll, the supporting mechanism controls the pole roll to rotate, so that the burrs or dust formed on the edge of the pole roll due to cutting are brushed away by the bristles 13 of the dust removal brush 2. A negative pressure hole 3 is provided on the dust removal brush 2, and the negative pressure mechanism can be an exhaust fan. The output end of the negative pressure mechanism is connected to the negative pressure hole 3 of the dust removal brush 2 by setting a negative pressure pipe 4.
