Dust removal mechanism

Abstract

The utility model provides a dust removal mechanism. The dust removal mechanism comprises a supporting seat; the first viscous roll shaft is rotationally mounted on the supporting seat; the second viscous roll shaft is rotationally mounted on the supporting seat; and the dust removal driving unit is connected with the supporting seat. The peripheral surface of the second viscous roll shaft is bonded with the peripheral surface of the first viscous roll shaft, and the viscosity of the second viscous roll shaft is greater than that of the first viscous roll shaft. The dust removal driving unit drives the first viscous roller shaft to be close to or away from the tool. When the first viscous roll shaft is in contact with the tool, the first viscous roll shaft can clean sundries on the tool through viscosity; and sundries on the first viscous roll shaft can be cleaned through the second viscous roll shaft with high viscosity, namely, the sundries on the tool can be transferred to the second viscous roll shaft from the first viscous roll shaft. Thus, compared with a cleaning mode of a traditional blowing nozzle, through the viscous cleaning effect of the first viscous roller shaft and the second viscous roller shaft, the cleaning effect on the tool can be improved, and improvement of the cleanliness of the membrane is facilitated.
