[0038] The vibration mechanism 2 comprises a motor 201 installed in the main machine 1, the output end of the motor 201 is fixed with a disc 202, the upper end of the disc 202 is fixed with a convex shaft 203, the convex shaft 203 and the fixed frame 204 are in sliding connection, the fixed frame 204 and the main machine 1 are in sliding connection, the fixed frame 204 is fixed on the lower end face of the carrier 205; the carrier 205 and the guide rod 206 are in sliding connection, the guide rod 206 is symmetrically fixed on the upper end face of the main machine 1, the spring 207 is fixed between the carrier 205 and the main machine 1; the blowing mechanism 3 comprises a sealing cylinder 301 symmetrically fixed in the main machine 1, the piston 302 is in sliding connection with the sealing cylinder 301, the end of the piston 302 away from the sealing cylinder 301 is fixed with the fixed frame 204, the one-way air inlet valve 303 is installed on the lower end of the sealing cylinder 301, the one-way air outlet valve 304 is installed on the upper end of the sealing cylinder 301; the driving mechanism 4 comprises a first rotating shaft 401 bearing connected on the carrier 205, the first rotating shaft 401 and the main machine 1 are in sliding connection, the gear 402 is fixed on the first rotating shaft 401, the gear 402 and the convex tooth plate 403 are in meshing connection, the convex tooth plate 403 is fixed in the main machine 1, the first rotating shaft 401 is connected with the one-way air outlet valve 304 through the rotary joint and the conduit;

[0039] After the device is assembled, as Figures 1-8As shown, the starting motor 201 drives the disc 202 and the convex shaft 203 to rotate, and the sliding action between the convex shaft 203 and the fixed frame 204 drives the carrier 205 and the screening mechanism 5 to vibrate orderly, so that the screen disc 502 realizes the screening of the new material metal powder, and further realizes the classification of different new material metal powder particles. When the fixed frame 204 moves orderly, the piston 302 is driven to move synchronously, and the sliding action between the piston 302 and the sealing cylinder 301 can realize the exhaust function of the sealing cylinder 301, so that the gas in the sealing cylinder 301 is output in one direction. The output gas enters the gas distribution plate 508 through the through hole on the first rotating shaft 401, the connecting piece 504 and the second rotating shaft 505, and is sprayed outwards through the gas outlet 509 on the gas distribution plate 508. Since the gas outlet 509 is located below the screen mesh on the screen disc 502, the high-speed airflow sprayed through the gas outlet 509 can blow off the powder particles that block the screen mesh on the screen disc 502, thereby avoiding the influence of particle blockage on normal screening. Under the action of high-speed airflow, the material on the screen disc 502 can be blown, so that the powder particles can collide with each other. Through the collision of powder particles, small particle materials adhered to the surface of large particles can be detached, further ensuring the separation quality of the material. When the carrier 205 moves, the first rotating shaft 401 and the gear 402 move synchronously, and the meshing transmission action between the gear 402 and the convex tooth plate 403 can make the first rotating shaft 401 rotate orderly, thereby driving the connecting piece 504, the second rotating shaft 505 and the gas distribution plate 508 to rotate. Through the rotation of the gas distribution plate 508, the position of the airflow blown out of the gas outlet 509 can be adjusted to realize the overall unblocking of the screen mesh on the screen disc 502, thereby ensuring the normal operation of the device.

[0040] After the material screening is completed, the screening mechanism 5 is disassembled according to the above principle, and the powder particles carried in the plurality of screen discs 502 and the bottom supports 501 are weighed to determine the particle size distribution of the new material metal powder.
