[0027] Among them, a positioning shaft 6 is fixedly connected inside the sliding rod 3, an axial hole 7 is opened on the outer wall of the filter frame 4, and the positioning shaft 6 is connected to the axial hole 7 by bearings. When the screening is completed, the filter frame 4 can be rotated around the positioning shaft 6, the filter screen can be turned over, and the residual metal material on the filter screen can be cleaned by vibration again.

[0028] A fine filter 8 is provided inside the filter frame 4. Through holes are provided at both ends of the fine filter 8. The through holes allow the fingers of the staff to pass through, so that the filter can be easily pulled out for replacement and cleaning. A chute 10 is provided on the inner wall of the filter frame 4. The fine filter 8 is slidably connected to the chute 10, so that the fine filter 8 can be easily disassembled, replaced, and better adapted to the filtration of metal powders of different fineness, and the unfiltered metal powder can be recovered.

[0029] Both ends of the top and bottom of the filter frame 4 are provided with material guiding slopes 15, and the filter screen is positioned deep in the filter frame 4, so as to reduce the flying metal powder during the vibration process.

[0030] Vibration motors 9 are embedded and fixedly connected at both ends of the filter frame 4, and installation ports 11 are provided at both ends of the filter frame 4. Nylon bristles 14 are provided at the bottom of the installation port 11 near the outer port. When the fine filter 8 is pulled out for replacement, the metal powder remaining on the filter can be cleaned by the nylon bristles 14 to reduce the residue. At the same time, the staff arranges a tray at the bottom of the installation port 11 to recycle the metal powder.

[0031] Limiting frames 12 are provided at both ends of the filter frame 4. The two limiting frames 12 are located at the two ends of the corresponding installation openings 11. A limiting plate 13 is provided through the two limiting frames 12. The limiting plate 13 is inserted into the limiting frame 12 to fix the fine filter 8 and prevent the filter from falling out.

[0032] A dual-axis motor 16 is embedded and fixedly connected at the inner center of the base 1, and both driving shafts of the dual-axis motor 16 are fixedly connected with screws 17, and the outer walls of the two screws 17 are threadedly connected with connecting plates 18, and both ends of the connecting plates 18 are fixedly connected with pillars 19, and the top of the pillar 19 is slidably connected with a bracket 20, and the bottom of the bracket 20 and the inside of the pillar 19 are fixedly connected with a buffer spring 21, and the top of the bracket 20 is fixedly connected with a support 22, and the cross-section of the support 22 is L-shaped, and the top of the support 22 is fixedly connected with a rubber pad 23, and the top of the rubber pad 23 is in contact with the bottom of the filter frame 4, so that the filter frame 4 is positioned on the top of the support 22 and in contact with it, and vibrates in cooperation with the vibration motor 9.

[0033] When in use, first connect the dual-axis motor 16 and the two vibration motors 9 to the external power supply, pour the metal dry powder to be filtered into the center of the fine filter 8, and spread the powder as gradually as possible. At this time, the four supports 22 are respectively located at the four corners of the filter frame 4, and the elasticity of the support spring 5 in this device is lower than that of the buffer spring 21.

[0034] Start one of the vibration motors 9 to generate vibration, so that the filter frame 4 vibrates to facilitate the metal powder to be better filtered by the filter screen. At the same time, a metal powder collection tray is set on the base 1 at the bottom of the filter screen. Although the slide rod 3 is slidably connected to the fixed tube 2, and the bracket 20 is slidably connected to the support 19, there is a certain gap between the two sliding parts, which facilitates the vibration of the filter frame 4 to compress the spring to produce a certain amplitude.

[0035] The two vibration motors 9 start and stop alternately to vibrate the filter frame 4 and filter the metal powder. When the filtering is completed, a part of the metal powder that does not meet the size requirements will remain on the top of the filter. At this time, the dual-axis motor 16 is started to drive the screw 17 to rotate, and the two connecting plates 18 are driven to move to both sides, so that the pillar 19 gradually separates from the filter frame 4. When the support 22 separates from the filter frame 4, the staff can flip the filter frame 4 180 degrees around the positioning axis 6, and then start the vibration motor 9 to vibrate the filter frame 4 to vibrate the remaining metal powder on the filter frame 4 for recovery. Then flip it back again, and support the support 22 to the four corners of the filter frame 4 again, pour in the metal powder to be filtered, and repeat the above operation to obtain ultrafine metal dry powder.

[0036] After the entire filtering process is completed, the unfiltered larger metal powder is recovered. If there is metal powder stuck in the fine filter 8, the limit plate 13 is pulled out from the limit frame 12, and then the fine filter 8 is pulled out. During the extraction, the filter is in contact with the nylon bristles 14 at the bottom of the installation port 11. The nylon bristles 14 are used to further sweep the residual metal powder out of the mesh, so that the filter is cleaned and the metal powder is fully recovered. At the same time, it is convenient to remove the fine filter for maintenance and replace it with a new filter.

[0037] Although the present invention has been described above with reference to the embodiments, various modifications may be made thereto and parts thereof may be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the various features in the embodiments disclosed in the present invention may be used in combination with each other in any manner, and the fact that these combinations are not exhaustively described in this specification is only for the sake of omitting space and saving resources. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
