[0023] Through the screening box 1, the storage container 5, the fixed block 6 and the two inclined plates 8 can be used to add the crushed metal powder from the feed hopper 2 to the inner cavity of the screening box 1. At this time, the two inclined plates 8 will cause the crushed metal powder to fall into the top of the screen 91. Since two motors 10 are fixedly installed on the top of the fixed block 6, and a bracket 9 is inserted into the interior of the fixed block 6, and a screen 91 is installed inside the bracket 9, the two motors 10 are started to drive the two eccentric wheels 11 to rotate along the two transmission blocks 92, so that the two transmission blocks 92 drive the bracket 9 and the screen 91 to move up and down, thereby screening the metal powder on the top of the screen 91. When the screening is completed, the protective door 3 is opened to clean the large particles of impurities on the surface of the screen 91, thereby improving the efficiency of metal powder screening.

[0024] See Figure 2 、 Figure 3 The feed hopper 2 is kept perpendicular to the screen 91, and a protective shell 7 is installed on the top of the fixed block 6 and outside the two motors 10. The bottom of the screen 91 is kept perpendicular to the storage container 5, and the storage container 5 is slidably connected to the inside of the screening box 1. The touch all-in-one machine 4 is connected to the two motors 10 through a wire.

[0025] Through the fixing block 6, the two protective shells 7 and the two motors 10 can be installed respectively. Since the feed hopper 2 is kept vertical to the screen 91, the bottom of the screen 91 is kept vertical to the storage container 5, and the storage container 5 is slidably connected to the inside of the screening box 1, the crushed metal powder can be added from the feed hopper 2 to the inner cavity of the screening box 1, and the crushed metal powder will fall to the top of the screen 91 through the two inclined plates 8. At the same time, by starting the two motors 10 to drive the two eccentric wheels 11, the two transmission blocks 92 are driven to drive the screen 91 and the bracket 9 to move up and down to screen the metal powder, and the screened metal powder falls to the inner wall of the storage container 5, so that the screened metal powder can be collected.

[0026] See Figure 3 、 Figure 4 A slot 61 is provided on the inner side of the fixed block 6, the bracket 9 is connected to the inner wall of the slot 61, and two transmission blocks 92 are installed on the top of the bracket 9. At the same time, the tops of the two screens 91 are connected to the two eccentric wheels 11. A limiting rod 62 is installed inside the slot 61, and the limiting rods 62 are respectively inserted into the inner walls of the bracket 9. At the same time, the screen 91 is fixedly installed inside the bracket 9. The bottom of the inner wall of the slot 61 and the outer wall of the limiting rod 62 are fixedly connected with a spring 63, and the upper end of the spring 63 is fixedly connected to the bottom of the bracket 9.

[0027] The limiting rod 62, spring 63 and bracket 9 can be installed through the slot 61 opened on the inner side of the fixed block 6. Since the two transmission blocks 92 are installed on the top of the bracket 9, the bottom of the inner wall of the slot 61 and the outer wall of the limiting rod 62 are fixedly connected with a spring 63, and the upper end of the spring 63 is fixedly connected to the bottom of the bracket 9. Then, the two motors 10 are started to drive the two eccentric wheels 11 to rotate along the two transmission blocks 92, which will cause the two transmission blocks 92 to drive the bracket 9 and the screen 91 respectively, and the compression spring 63 moves up and down along the limiting rod 62, thereby being able to screen the metal powder on the top of the screen 91.

[0028] During operation, the storage container 5, the fixed block 6 and the two inclined plates 8 can be adjusted through the screening box 1, so that the crushed metal powder can be added from the feed hopper 2 to the inner cavity of the screening box 1. At this time, the two inclined plates 8 will cause the crushed metal powder to fall into the top of the screen 91. Since two motors 10 are fixedly installed on the top of the fixed block 6, and a bracket 9 is inserted into the interior of the fixed block 6, and a screen 91 is installed inside the bracket 9, the two motors 10 are started to drive the two eccentric wheels 11 to rotate along the two transmission blocks 92, so that the two transmission blocks 92 drive the bracket 9 and the screen 91 to move up and down, thereby screening the metal powder on the top of the screen 91. After the screening is completed, the protective door 3 is opened to clean the large particles of impurities on the surface of the screen 91, thereby improving the efficiency of metal powder screening.

[0029] Through the fixing block 6, the two protective shells 7 and the two motors 10 can be installed respectively. Since the feed hopper 2 is kept vertical to the screen 91, the bottom of the screen 91 is kept vertical to the storage container 5, and the storage container 5 is slidably connected to the inside of the screening box 1, the crushed metal powder can be added from the feed hopper 2 to the inner cavity of the screening box 1, and the crushed metal powder will fall to the top of the screen 91 through the two inclined plates 8. At the same time, by starting the two motors 10 to drive the two eccentric wheels 11, the two transmission blocks 92 are driven to drive the screen 91 and the bracket 9 to move up and down to screen the metal powder, and the screened metal powder falls to the inner wall of the storage container 5, so that the screened metal powder can be collected.

[0030] The limiting rod 62, spring 63 and bracket 9 can be installed through the slot 61 opened on the inner side of the fixed block 6. Since the two transmission blocks 92 are installed on the top of the bracket 9, the bottom of the inner wall of the slot 61 and the outer wall of the limiting rod 62 are fixedly connected with a spring 63, and the upper end of the spring 63 is fixedly connected to the bottom of the bracket 9. Then, the two motors 10 are started to drive the two eccentric wheels 11 to rotate along the two transmission blocks 92, which will cause the two transmission blocks 92 to drive the bracket 9 and the screen 91 respectively, and the compression spring 63 moves up and down along the limiting rod 62, thereby being able to screen the metal powder on the top of the screen 91.

[0031] In summary, the device starts two motors 10 to drive two eccentric wheels 11, which rotate along the two transmission blocks 92, so that the two transmission blocks 92 drive the bracket 9 and the screen 91 respectively, and the compression spring 63 moves up and down along the limit rod 62, thereby being able to screen the metal powder on the top of the screen 91. After the screening is completed, the protective door 3 is opened to clean the large particles of impurities on the surface of the screen 91, thereby improving the efficiency of metal powder screening.
