The first ball screw 31 drives the telescopic plate 412 to rise and fall through the first connecting rod 413, which can be adjusted according to the length of the graphite rods. The graphite rods are sent to the loading device 1 in batches by the conveyor belt, and the guide seat 5 guides the No. 1 graphite rod into the vertical cylinder 4. The No. 1 graphite rod can be first sent to the first guide cylinder 51 and the second guide cylinder 52 through the inclined inclined plate 54.

[0041] See also Figure 5-8 The bottom of the nozzle 73 is connected with a water pipe 74, and the water pipe 74 runs through the interior of the base 6. A drain port is opened at one end of the flushing seat 7, and the drain port is connected with the flushing chamber 71.

[0042] During operation, the graphite rods in the waste lithium battery are first taken out and placed on the conveyor belt. The first ball screw 31 drives the telescopic plate 412 to rise and fall through the first connecting rod 413, which can be adjusted according to the length of the graphite rods. The graphite rods are sent to the feeding device 1 in batches by the conveyor belt. The guide seat 5 guides the No. 1 graphite rod into the vertical cylinder 4.

The mesh plate 72 supports the bottom end of the No. 1 graphite rod. By connecting the water pipe 74 to the external water pump, and then spraying water through the nozzle 73 to wash the No. 1 graphite rod, the waste water flows back to the inside of the washing chamber 71 and is discharged through the drain port. When the movable brush seat 8 is separated from the bottom of the vertical cylinder 4, the adjusting motor 32 drives the mounting column 3 to rotate, and the vertical cylinder 4 can be driven to rotate synchronously through the straight partition plate 41 and the telescopic plate 412 to adjust the new small material opening. When it reaches the bottom of the material guide seat 5, the mounting column 3 stops rotating, and the movable brush seat 8 rises and enters the bottom of the vertical cylinder 4. At this time, the top of the No. 1 graphite rod stays inside the brushing channel 83, and the No. 2 graphite rod can continue to be vertically put into the vertical cylinder 4.

During the lifting process, the cleaning brush 84 can brush the surface of the graphite rod. When the movable brush seat 8 rises to the highest point, the top of the graphite rod is separated from the movable brush seat 8, and the cleaned graphite rod can be taken out. The batches of graphite rods can be separated and cleaned as a whole. During the cleaning process, the graphite rods will not collide with each other and be damaged.
