Automatic screening and packaging device for antioxidant powder coating

The utility model belongs to the technical field of powder coating production, and particularly relates to an anti-oxidation powder coating automatic screening and packaging device which comprises a base provided with a packaging mechanism, two symmetrically-arranged L-shaped supports are welded to the outer wall of the top of the base, and the same screening box is welded to the outer walls of the upper portions of the opposite sides of the two L-shaped supports. A feeding hopper is arranged at the top of the screening box, a discharging pipe is arranged at the bottom of the screening box, and a cooling mechanism and a screening mechanism are sequentially arranged on the screening box. The cooling mechanism is arranged, so that the powder coating can be fully condensed and cooled during discharging and packaging, the caking probability of the powder coating is reduced, and subsequent sales is facilitated; and the screening mechanism is arranged, vibration is continuously generated on a screen through startin
