Specifically, in use, the material is placed on the conveying device 10 so that the material moves on the conveying device 10, when the material moves to the anti-static device 20, the anti-static device 20 removes the static electricity on the surface of the material, so that the dust on the surface of the material loses strong adhesion, when the material moves to the flushing device 30, the dust on the surface of the material can be more efficiently blown off by the airflow, so that the dust can be better sucked away by the negative pressure device 40, in this way, the material passes through the anti-static device 20 first and then passes through the flushing device 30, which can more efficiently and sufficiently remove the dust, and can significantly reduce the airflow velocity and airflow volume of the flushing device 30, which can avoid the dust flying around, and can better save energy consumption.

[0022] The destaticizing device 20 in the embodiment comprises an upper ion air pipe 21 arranged horizontally, a plurality of upper ion air nozzles 22 arranged on the lower side of the upper ion air pipe 21, and an ion air generator connected with the ion air pipe; the upper ion air pipe 21 is arranged above the conveying device 10 and is perpendicular to the conveying direction, and the upper ion air nozzles 22 are arranged towards the conveying device 10. The destaticizing device 20 further comprises a lower ion air pipe 24 parallel to the upper ion air pipe 21, and a plurality of lower ion air nozzles 25 arranged on the lower ion air pipe 24; the lower ion air pipe 24 is connected with the ion air generator; the lower ion air pipe 24 is arranged below the conveying device 10, and the lower ion air nozzles 25 are arranged towards the conveying device 10. Specifically, the ion air is different from the common air, and is composed of ionized molecules instead of molecules in natural state.

Specifically, the negative pressure machine generates negative pressure, so that the dust in the cover body 31 enters the dust collecting hopper 41 and is discharged in a directional manner by the negative pressure machine.

[0028] The conveying device 10 in the embodiment comprises a pair of horizontally arranged support plates 11, a plurality of conveying rollers 12 rotatably arranged between the pair of support plates 11, a support column 13 supporting the support plates 11, and a power mechanism driving the conveying rollers 12 to rotate. Specifically, the conveying device 10 uses a conventional roller structure, which can better blow the lower surface of the material.

[0029] In summary, the device for automatically removing dust from the outer surface of the material in the embodiment can move the material on the conveying device 10 when the material is placed on the conveying device 10, remove the static electricity on the surface of the material by the destaticizing device 20 when the material moves to the destaticizing device 20, so that the dust on the surface of the material loses strong adhesion, and blow the dust on the surface of the material more efficiently by the air flow when the material moves to the flushing device 30, so that the dust can be better sucked away by the negative pressure device 40. In this way, the material can pass through the destaticizing device 20 and then the flushing device 30, which can more efficiently and sufficiently remove the dust, and can significantly reduce the flow rate and flow volume of the air flow of the flushing device 30, avoid the dust from flying around, and better save energy consumption.
