When liquid is required to be filled into the infusion bag, first, the telescopic cylinder 410 controls the telescopic shaft 411 to drive the lifting cylinder 420 to move along the guide rail 300 to a first predetermined distance, and the lifting cylinder 420 controls the lifting shaft 421 to drive the filling assembly 600 to move to a second predetermined distance in a second direction, so that the filling nozzle 610 is inserted into the hose 100. In this process, the open clamp cylinder 520 controls the clamp 511 to clamp the hose 100, so that the filling nozzle 610 can be smoothly inserted into the hose 100.

Then, the opening cylinder 520 controls the opening of the nip 511 so that the hose 100 can be separated from the nip 511. The telescopic cylinder 410 controls the telescopic shaft 411 to drive the lifting cylinder 420 to move a third predetermined distance along the guide rail 300 in a third direction, and simultaneously to drive the filling assembly 600 connected to the lifting shaft 421 to move a third predetermined distance in the third direction, so that the infusion bag moves to a predetermined position, and the squeezing part 720 of the squeezing plate 700 squeezes the flexible tube 100.

Finally, the filling pneumatic valve 630 controls the fluid conduit 620 to be connected so that the filling fluid flows in the fluid conduit 620 to the filling nozzle 610 and is filled into the infusion bag through the hose 100. When the filling amount reaches a predetermined value, the filling pneumatic valve 630 timely controls the liquid pipe 620 to be disconnected so as to avoid waste of the filling liquid. At this time, the infusion bag is filled.
