Textile dust collecting device

The invention belongs to the technical field of textile processing, and discloses a textile dust collecting device which comprises a cleaning box and a collecting box communicated with the interior of the cleaning box. Through cooperation of the separation assembly, the motor and other structures, the trigger rod rotates and pushes the contact rod and the supporting rod to rotate and pick up the textile cloth, fiber gaps in the textile cloth can be enlarged, dust attached to the textile cloth is exposed, the textile cloth is continuously whipped by the extraction assembly at the moment, and the dust falls off the textile cloth; the elastic force of the arc-shaped spring telescopic rod and the toughness generated after the textile cloth is shocked can force the textile cloth, the contact rod and the supporting rod to return to the initial position and impact the filtering assembly, vibration generated when the textile cloth impacts the filtering assembly can enable dust on the textile cloth to fall off, and th
