[0035] Specifically: The input end of the vacuum cleaner 14 is communicated with one end of the particle suction pipe 15. The other end of the particle suction pipe 15 extends to the outside of the cross bar 11. The surface of the particle suction pipe 15 is movably connected to the inner cavity of the cross bar 11. The filter screen 16 is fixed on one side of the inner cavity of the particle suction pipe 15, which can prevent the particle suction pipe 15 from being blocked when particles enter. One side of the conical pot 17 is fixed to the top end of the spring rod 18, the other side is fixed to one side of the vibrating plate 19, and the bottom is slidably connected to the inner cavity of the partition plate 4. By pushing the front end of the bottom of the vibrating plate 19 by the cam 10, the conical pot 17 can vibrate, so that the internal particles will not be blocked at the bottom of the inner cavity. There are two right-angle plates, and an anti-blocking brush 20 is fixedly connected to one side of each of them, so as to facilitate the cleaning of the filter screen 16;

[0036] One end of the feed pipe 21 extends to one side of the inner cavity of the anti-leakage cylinder 2 and is communicated with one end of the feeding rod 22.

The ventilation opening can ventilate the screening cylinder 3, and the gap size of the dust-proof plate will not allow the particles to escape.

[0037] The working principle of the present utility model is as follows: When it is necessary to carry out rotary screening and discharging of powder coatings, firstly, the unscreened powder particles are introduced into the feeding rod 22 through the valve and the feeding pipe 21, and the powder particles are introduced into the screening cylinder 3 through the discharge port of the feeding rod 22. Then, the double-shaft motor 5 is started. The double-shaft motor 5 drives the driving bevel gear 12 and the worm 6 to rotate simultaneously. The driving bevel gear 12 drives the driven bevel gear 13 to rotate, the driven bevel gear 13 drives the cross bar 11 to rotate, and the cross bar 11 drives the screening cylinder 3 to rotate, so as to carry out rotary screening of the powder particles;

[0038] The rotation of the worm 6 drives the worm wheel 8 to rotate, the worm wheel 8 drives the rotating rod 7 to rotate, the rotating rod 7 drives the eccentric wheel 9 to rotate, the eccentric wheel 9 drives the cam 10 to rotate, and the rotation of the cam 10 pushes the vibrating plate 19. Through the cooperation of the spring rod 18, the vibrating plate 19 generates a vibration phenomenon. The vibrating plate 19 drives the conical pot 17 to vibrate, so that the particles screened out in the screening cylinder 3 will not block the conical pot 17, and the particles fall into the discharge pipe 23 through the bottom of the inner cavity of the conical pot 17, and the discharging is completed through the discharge pipe 23;

[0039] When screening is carried out inside the screening cylinder 3, the cross bar 11 drives the right-angle plate to rotate, and the right-angle plate drives the anti-blocking brush 20 to rotate, so as to prevent some small-particle powders from entering the particle suction pipe 15. When the screening work is completed, the switch of the vacuum cleaner 14 can be turned on. The vacuum cleaner 14 works to make the particle suction pipe 15 adsorb the remaining particles inside the screening cylinder 3, so that the remaining particles are discharged to the output end of the vacuum cleaner 14 through the particle suction pipe 15, and the large particles are discharged through the output end, so that the rotary screening and discharging work of the powder coatings can be completed in this way.
