In this structure, the first screening mesh frame 3 and the second screening mesh frame 4 are respectively provided with a first screening mesh 302 and a second screening mesh 401. The second screening mesh frame 4 is subjected to vibration screening treatment by the existing vibration motor, so that the first screening mesh frame 3 and the second screening mesh frame 4 respectively perform primary screening and secondary screening treatment on the powder coating through the first screening mesh 302 and the second screening mesh 401. A third discharge channel 9 with an inclined structure is provided below the second screening mesh frame 4, and the outlet at the lowest end of the third discharge channel 9 is located between the first discharge channel 301 and the second discharge channel 402. This structure can collect and process the screened materials through the first discharge channel 301, the second discharge channel 402 and the third discharge channel 9 arranged at different positions. A loading seat 8 is clamped on one side of the upper end of the mounting shell 5, and a feed plate 2 and a positioning ring 801 are clamped in the loading seat 8. The feed plate 2 is clamped by The punching machine is evenly spaced to provide feed holes 201, and the feed holes 201 are of a conical structure. A rotating plate 7 of a straight-line structure is provided above the feed plate 2, and a rotating shaft 701 is screwed and fixed to the upper end of the rotating plate 7. Pushing brushes 702 are provided at the bottom and both ends of the rotating plate 7, respectively, and the pushing brushes 702 are provided in contact with the upper end of the feed plate 2 and the inner side of the positioning ring 801. This structure enables the rotating shaft 701 to be driven to rotate by an existing stepping motor, so that the rotating shaft 701 drives the rotating plate 7 to rotate in the loading seat 8, so that the rotating plate 7 cooperates with the pushing brush 702 to push the material on the feed plate 2 to move, thereby realizing uniform distribution of powder coatings. A loading barrel 6 is provided on the upper end cover of the loading seat 8, and a conical mounting cover 6 is provided in the middle of the inner side of the loading barrel 6. 01, and the driving structure of the rotating shaft 701 is installed in the conical mounting cover 601.

The positioning ring 801 is used for the installation and fastening of the feeding plate 2. The stepper motor installed in the conical mounting cover 601 drives the rotating plate 7 to rotate through the rotating shaft 701, so that the rotating plate 7 cooperates with the pushing brush 702 to push the powder coating on the feeding plate 2, so as to further make the powder coating uniform. Distribution, the screening device body 1 is driven by the vibration motor to make the first screening frame 3 and the second screening frame 4 screen synchronously. After the first screening frame 3 screens the powder coating through the first screening net 302, the screened powder coating falls on the second screening net 401, and then is screened by the second screening net 401. The powder coating that is not screened by the first screening frame 3 and the second screening net 401 is discharged from the first discharge channel 301 and the second discharge channel 402 for collection, while the powder coating screened by the second screening frame 4 is recorded in the third discharge channel 9 and then discharged, thereby completing a series of tasks.
