Description

Technical Field

[0060] Example 4:

[0061] See Figure 6 In this embodiment, the combination of brush, blower, suction and ultrasonic wave is used. During the rotation of the roller, the brush 3 is used to sweep away the dust on the surface of the roller, and the ultrasonic waves generated by the ultrasonic generator cavity are used to remove the dust with adhesion on the surface of the roller.
