The first discharging unit 113 includes a first notch 1131 formed on the outer side of the plane of the first guide track 112, a first outlet 1133 formed on the inner baffle 1132 of the first guide track 112 behind the first notch 1131, and a first output track 1134 fixedly mounted on the first vibration table 111 disposed below the first outlet 1133;

The second discharging unit 114 includes a second outlet 1141 located behind the first outlet 1133 and having the same specifications as the first outlet 1133, a second notch 1142 located behind the first notch 1131 and having the same specifications as the first notch 1131, a third outlet 1143 located behind the second outlet 1141 and higher than the second outlet 1141, and a second output track 1144 fixedly mounted on the first vibration table 111 is provided below the third outlet 1143, and a gear lever 1145 is provided on the third outlet 1143 toward the output end of the first guide track 112;

The third discharging unit 115 includes a third output track 1151 which is fixedly mounted on the first vibration table 111 and is located at the output end of the first guide track 112 .

In this embodiment, by setting up the first vibration mechanism 11, the dust cover 101, the back cover 102, and the nut column 103 that are integrally injection-molded are screened in an orderly manner, which is convenient for the early processing of the dust cover 101, the back cover 102, and the nut column 103, as only one machine is needed to injection-mold the three products, saving costs and raw materials. At the same time, the dust cover 101, the back cover 102, and the nut column 103 after screening can be assembled in an orderly manner, thereby improving the efficiency of manual sorting, and is suitable for mass production.

In detail, first, the dust cover 101, the rear cover 102, and the nut column 103 output by injection molding are mixed and poured into the first vibration table 111, and the first vibration table 111 is started, and the mixed material is output in an orderly manner. When the nut column 103 with a larger width moves to the first notch 1131, most of the nut column 103 falls outward and flows back to the bottom of the first vibration table 111 to wait for screening again. Then the dust cover 101 enters the first output track 1134 through the first outlet 1133 and is automatically output. Then the mixed material passes through the second discharging unit 114, and the nut column 103 with a larger width that has not been output in the previous pass falls again through the second notch 1142, and the dust cover 101 that has not successfully fallen from the first outlet 1133 falls back to the first vibration table 111 through the second outlet 1141 to wait for the next screening. Then the rear cover 102 moves to the third outlet 1143 and is output from the second output track 1144. Finally, only the nut column 103 remains on the first guide track 112 and is output backward.

In addition, the screened dust cover 101 is collected in the first temporary storage box 12, the screened back cover 102 is collected in the second temporary storage box 13, and the screened nut column 103 is collected in the third temporary storage box 14. At the same time, the only product remaining in the first vibration table 111 is the nut column 103. Finally, the nut column 103 is poured into the third temporary storage box 14 for collection together. Subsequently, the three products can be placed in the corresponding vibration table of the next process by manual handling or conveyor belt transmission.

It should be noted that the purpose of the first guide rail 112 being tilted inward is to prevent the product from falling outward during vibration, but to trap it between the first guide rail 112 and the baffle 1132; utilizing the height difference between the third outlet 1143 and the second outlet 1141, the dust cover 101 and the back cover 102 fall in batches; due to the fast vibration speed, the rear cover 102 can be dropped back to the third outlet 1143 for normal output through the shift rod 1145.
