Working Principle of Vacuum Filling Machine (Self-discharging Type)

Open the hand-held valve and connect with the air source. Put the bottle to be filled under the filling head, and make use of the elasticity of the shelf of the bottle to make the bottle stand upright and sealed with the filling head. At this time, the cam opens the mechanical valve, closes the vacuum bottle valve and opens the suction valve, which makes the vacuum generator produce vacuum (negative pressure).

Form a vacuum environment system (vacuum bottle - filling head - filling bottle - filling head silica gel tube). Vacuum suction causes the material to be poured into the bottle. When the inner material of the bottle rises to the height of the outer casing of the filling head. As the vacuum suction passes through the outer sleeve, the inner material of the bottle is sucked into the vacuum bottle so that the inner material of the bottle remains at a certain height until the filling bottle is removed. The mechanical valve closes and the vacuum generator stops producing vacuum. The suction pipe is closed. The valve of the vacuum bottle is opened, and the inner material of the vacuum bottle is flowed into the barrel due to gravity, thus completing a filling cycle.
