Piston type non-contact dust removal device

The invention discloses a piston type non-contact dust removal device. The dust removal device comprises a rectangular shell, a plurality of airflow openings formed in a bottom plate of the rectangular shell, an extraction opening formed in an end plate of the rectangular shell and a piston type air blowing mechanism arranged in the rectangular shell, and the plurality of airflow openings and the extraction opening are all communicate with an inner cavity of the rectangular shell. According to the device, the piston type air blowing mechanism is arranged, airflow is blown into the piston type air blowing mechanism, the piston type air blowing mechanism drives a blocking piece of the piston type air blowing mechanism to conduct continuous blocking and opening operation on the airflow openings, high-frequency intermittent wind is blown out, a coiled material generates high-frequency vibration, and therefore dust foreign matter floats, finally the dust foreign matter is taken away through air exhaust, and the du
