As shown in fig. 1, a liquid tank structure 100 of a liquid filling machine is provided at an upper side inside a cabinet 21 of the liquid filling machine 20, and is connected to a plurality of filling heads 23 through a plurality of liquid outlet regulating valves 22 so as to discharge the filling heads 23, see fig. 2 to 3.
As shown in fig. 1 and 2, the liquid tank structure 100 of the present invention includes a tank body 110, a first liquid inlet pipe 120, a liquid return pipe 130, and a liquid return pump 140.
The inner chamber of box body 110 is separated into first chamber A that is used for to the unloading of filling head 23 and is used for holding the second chamber B of the overflow from first chamber A through vertical baffle 111, and the height of baffle 111 is less than the height of box body 110 for first chamber A and second chamber B are in the upside intercommunication, and first chamber A liquid is full back, and liquid can be followed the upside surface of baffle 111 and is overflowed to second chamber B.
The first liquid inlet pipe 120 is used for feeding liquid into the first chamber a, and the flow rate of the fed liquid is larger than the liquid outlet flow rate of the filling heads 23 (the total liquid outlet flow rate of the plurality of filling heads 23), 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 130 is connected to the second chamber B and connected to the first liquid inlet pipe 120 via the liquid return pump 140, so that the liquid in the second chamber B is pumped to the first liquid inlet pipe 120 through the liquid return pipe 130.
During operation, last feed liquor to first chamber A through first feed liquor pipe 120, first chamber A liquid is full, and the liquid that spills over flows to second chamber B, and the liquid in the second chamber B is taken back for first feed liquor pipe 120 through returning liquid pipe 130, can make first chamber A keep the liquid full state like this to maintain the constancy of pressure in the first chamber A, avoid the filling volume to produce the error.
The utility model discloses pressure when liquid tank structure can keep the filling is invariable, effectively avoids producing filling volume error.
In this embodiment, as shown in fig. 1-3, the utility model discloses still have the second feed liquor pipe 150 that is used for to the feed liquor of second chamber B, be used for detecting the liquid level detection device of the liquid level of second chamber B and according to the liquid level detection device's detection signal control second feed liquor pipe 150 feed liquor advance liquid control valve 160, advance liquid control valve 160 and locate on second feed liquor pipe 150.
The first chamber a and the second chamber B are arranged in front and rear, the first liquid inlet pipe 120 horizontally penetrates from the upper portion of the rear side of the box body 110 and horizontally extends forward to the upper portion of the first chamber a, the liquid return pipe 130 is connected with the bottom of the second chamber B, and the second liquid inlet pipe 150 penetrates downward from the upper side of the box body 110 to the upper portion of the second chamber B.
