The automatic graphite powder filling device according to claim 4, characterized in that: The graphite powder automatic filling device also includes an extension mechanism, which includes a fixed ring and a plurality of sleeves. A plurality of extension rods are arranged on the outer side of the fixed ring. The fixed ring is fixedly connected to the extension rod and is sleeved on the end of the extension rod away from the hydraulic push rod. The plurality of extension rods are respectively slidably connected to the corresponding sleeves and are located in the sleeves. The plurality of sleeves are respectively fixedly connected to the L-shaped rod and are located on the outer side of the L-shaped rod.

6. The automatic graphite powder filling device according to claim 5, characterized in that: A collar is disposed on the outer side of the lifting rod, a limiting block is disposed on the inner side of the collar, a supporting rod is disposed on the outer side of the collar, a plurality of limiting grooves are provided on the outer side of the lifting rod, and the limiting blocks are located in the limiting grooves, and the supporting rod is fixedly connected to the workbench and is located on the workbench.

7. A graphite powder automatic filling process, applied to the graphite powder automatic filling device as claimed in claim 6, characterized in that: The steps include: First, the device is moved to the side of the graphite powder processing device, and then the material is added into the storage cylinder; The third motor is started to drive the rotating rod, and the lifting rod moves upward under the action of the internal thread, so that the height of the storage barrel is adjusted to be consistent with the height of the feeding port of the graphite powder processing device; Then, the second motor is started to drive the screw, and the convex block is moved under the action of the thread groove and adjusted to a position aligned with the feed port of the graphite powder processing device; Then, the hydraulic push rod is started to push the extension rod, so that the storage barrel moves to the top of the feeding port of the graphite powder processing device; Finally, the first motor is started to drive the rotating shaft, and the spiral blade rotates under the action of the rotating shaft. The material is discharged from the discharge pipe under the action of the spiral blade and enters the feed port of the graphite powder processing device, completing the automatic filling operation.
