The first inlet pipe 1220 is used for feeding liquid into the first chamber a, and the flow rate of the fed liquid is greater than the outflow flow rate of the filling heads 1600 (the total outflow flow rate of the filling heads 1600), so that the first chamber a can be always kept full of liquid, and the pressure in the first chamber a is kept constant.
The liquid return pipe 1230 is connected to the second chamber B and connected to the first liquid inlet pipe 1220 via the liquid return pump 1240, so that the liquid in the second chamber B is pumped to the first liquid inlet pipe 1220 through the liquid return pipe 1230.
When the liquid storage bin 1200 works, liquid is continuously fed into the first cavity a through the first liquid feeding pipe 1220, the first cavity a is full of liquid, overflowing liquid flows to the second cavity B, and the liquid in the second cavity B is pumped back to the first liquid feeding pipe 1220 through the liquid returning pipe 1230, so that the first cavity a is always kept in a full state of liquid, the pressure in the first cavity a is kept constant, and errors caused by filling quantity are avoided.
As shown in fig. 1 and 2, the conveyor 1300 is used to horizontally transport a plurality of bottles to be filled into and out of the cabinet 1100.
As shown in fig. 1, the bottle blocking and placing mechanism 1400 is configured to block a plurality of bottles fed into the cabinet 1100 back and forth, so that the plurality of bottles are located just below the plurality of filling heads 1600, and after filling is completed, the bottles are placed so that the plurality of bottles are sent out of the cabinet 1100 along with the conveyor 1300.
The conveyor 1300 and the bottle blocking and placing mechanism 1400 are common mechanisms, and are not described in detail here.
