The top of the vibrating plate 171 is provided with three screening holes 193 arranged from small to large, and a limit plate 194 is provided at the middle of the top of the vibrating plate 171. When the circular workpiece is to be screened, first, the rotating rod 12 is driven to rotate, driving the disc 13 and the fixed block 14 to rotate, and the top of the crank 15 is rotated and installed at the bottom of the connecting rod 16. When the disc 13 and the fixed block 14 rotate, the crank 15 is driven to move up and down, thereby driving the connecting rod 16 and the moving rod 17 to move up and down. By setting a first spring 192, when the moving rod 17 moves downward, the first spring 1 The elastic force of 92 will bounce the moving rod 17 upward, causing the moving rod 17 to regularly collide with the connecting block 18, thereby causing the vibration plate 171 to vibrate. At this time, the workpiece to be screened is vertically placed in the limiting plate 194, and the vibration plate 171 is set to a slightly inclined state and the vibration generated by the vibration plate 171 causes the workpiece to slowly move downward, so that workpieces with larger or smaller diameters fall into different screening holes 193 respectively, thereby screening the workpieces.

[0030] By adopting the above technical solution and providing the second spring 3, the vibration frequency of the vibration plate 171 is made faster, thereby improving the screening efficiency.
[0031] A blocking plate 4 is fixedly mounted on one side of the top of the vibration plate 171 close to the fixing box 11 , and the blocking plate 4 is in contact with the limiting plate 194 .
[0032] By adopting the above technical solution and providing the blocking plate 4, it is possible to prevent the workpieces that have not entered the screening hole 193 from falling and thus causing damage to the workpieces.
[0033] A support plate 5 is fixedly mounted on one side of the fixed box 11 close to the rotating rod 12 , a motor 51 is fixedly mounted on the top of the support plate 5 , and an output end of the motor 51 is fixedly mounted coaxially with the rotating rod 12 .
[0034] By adopting the above technical solution and providing the motor 51 , the rotating rod 12 can be rotated, and the vibration plate 171 can be vibrated, so that the workpieces can be screened.
[0035] A support box 6 is fixedly installed on the side of the top of the bottom plate 1 away from the fixed box 11 , and two symmetrically distributed third springs 61 are fixedly installed on the top of the support box 6 . The top ends of the two third springs 61 and the bottom end of the vibration plate 171 are fixedly installed.
[0036] By adopting the above technical solution and providing the support box 6 and the third spring 61, the vibration plate 171 can be supported when vibrating, making it more stable during vibration, thereby improving the screening efficiency.
[0037] Working principle: When it is desired to screen the circular workpiece, first, the rotating rod 12 is driven to rotate, driving the disc 13 and the fixed block 14 to rotate, and the top of the crank 15 is rotated and installed at the bottom of the connecting rod 16. When the disc 13 and the fixed block 14 rotate, the crank 15 is driven to move up and down, thereby driving the connecting rod 16 and the moving rod 17 to move up and down. By setting the first spring 192, when the moving rod 17 moves downward, the elastic force of the first spring 192 will bounce the moving rod 17 upward, so that the moving rod 17 regularly hits the connecting block 18, thereby causing the vibration plate 171 to vibrate. At this time, the workpiece to be screened is vertically placed in the limit plate 194, and the vibration plate 171 is set to a slightly inclined state and the vibration generated by the vibration plate 171, so that the workpiece moves slowly downward, so that the workpiece with a larger or smaller diameter falls into different screening holes 193 respectively, thereby screening the workpiece. Compared with manual screening one by one, the work efficiency is greatly improved and the labor intensity of the staff is reduced;
[0038] Then, by setting the limiting plate 194, the workpiece can be limited so that it can fall into the screening hole 193;
[0039] Finally, by setting up the feed pipe 2, the workpiece can fall into the first collecting box 21 through the feed pipe 2 when falling into the screening hole 193, so that the workpiece can be collected. By setting up the second collecting box 22, workpieces with larger or smaller diameters can be collected. The second collecting box 22 is slightly smaller than the first collecting box 21, so that more precise workpieces can be collected.
[0040] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
