It will be appreciated that air pressure may be introduced into the cavity 322 via the air hole 3191 (e.g., 0.1MPa at the air charging connector 319), and then the lift cylinder 104 of the cup holder assembly at the powder filling station may drive the cup holder 103 to move up so that the cup body in the cup holder 103 is in abutment with the filling tube 307. As the cup continues to rise, the upward movement of the cup causes the movable sleeve 318 to move upward as the outer edge 1032 of the cup abuts the lower end of the movable sleeve 318. After the filling, the lifting cylinder of the cup supporting assembly located at the powder filling station descends, and due to the pressure of the gas inside the cavity 322, the movable sleeve 318 extends downwards under the action of the air pressure to drive the cup 1031 to move downwards, so that the cup 1031 and the filling tube 307 are reliably separated, and the cup hanging phenomenon is avoided. From this, solved among the prior art cup and the problem that the filling head is difficult to reliably separate and the phenomenon of hanging the cup appears.

Further, the fixed sleeve 317 is sleeved with a position-limiting fixed ring 320 above the movable sleeve 318. The limiting fixing ring 320 is formed with an annular extension part 3201 extending longitudinally downward to extend into the first hole 3181, and the annular extension part 3201 is respectively attached to the hole wall of the first hole 3181 and the outer wall of the fixing sleeve 317. The retaining ring 320 is also formed with an annular boss 3202 extending longitudinally upward and engaging the outer wall of the retaining sleeve 317. So set up, after cup 1031 docks with filling tube 307, the cup continues the in-process that rises, and the outer edge 1032 of cup drives movable sleeve 318 and shifts up, bumps spacing solid fixed ring 320 until movable sleeve 318 tops to the size that shifts up of movable sleeve 318 plays spacing effect.
