At the same time, the engagement between the reciprocating screw 17 and the screw nut drives the cleaning seat 10 and the nozzle 14 to adjust their positions, thereby enabling a comprehensive rinsing and cleaning of the bolts on the conveyor 6.
[0060] Reference Figures 3-6The oscillating mechanism includes a first gear ring 19, a second cavity 20, a first gear 21, and a reciprocating rotation mechanism. The first gear ring 19 is fixedly mounted on the cleaning ring 13. The second cavity 20 is opened inside the cleaning seat 10 and communicates with the first cavity 11. The first gear 21 is rotatably mounted inside the second cavity 20 and meshes with the first gear ring 19.

[0061] In this embodiment, during use, the bolts can fall from the discharge plate 3 onto the oil drain plate 7 during the discharge process, and then slide onto the conveyor 6 via the oil drain plate 7. During this process, the lubricating oil can fall into the collection bin 8 via the oil drain plate 7, which facilitates the initial separation and collection of the lubricating oil on the bolt surface, avoiding waste of lubricating oil. Then, the operator controls the third motor to work, which drives the conveyor belt and bolts to move by rotating the conveyor roller. During the movement of the bolts, cleaning agent can be introduced into the first cavity 11 through the first water supply pipe 15 and the second water supply pipe 16, and then sprayed and rinsed onto the bolt surface through the nozzle 14, which facilitates the cleaning of the lubricating oil on the bolt surface. During the cleaning process, the operation of the first motor 18 can drive the reciprocating screw 17 to rotate, and at the same time, the reciprocating screw 17 and the screw... The engagement of the nut causes the cleaning seat 10 and the nozzle 14 to adjust their positions, thereby enabling a thorough rinsing and cleaning of the bolts on the conveyor 6. Simultaneously, the operator controls the electric push rod 27, which drives the second rack 26 to reciprocate. The meshing of the second rack 26 with the second gear 25 drives the drive prism 23 to rotate. The sliding engagement of the drive prism 23 with the first drive port 22 drives the first gear 21 to reciprocate. The meshing of the first gear 21 with the first gear ring 19 drives the cleaning ring 13 to reciprocate, which in turn drives the nozzle 14 to swing. This allows the nozzle 14 to spray the bolt surface at different angles, further enhancing the cleaning effect on the bolts. After rinsing, the bolts fall into the collection box 28 under the conveyor belt for collection.
