Patent ID: 7464639

Claim:
An automatic liquid density-regulating device, comprising: a workbench provided with a preparation area, a stir area, and a storage area; a controlling mechanism located at a side of the workbench and connected with a clipping unit; a powder supply mechanism located vertically on the preparation area of workbench, holding at least one container unit; a weighing mechanism located on the preparation area of workbench and connected to the controlling mechanism; a liquid supply mechanism provided on the preparation area of workbench and adjacent the weighing mechanism and connected to the controlling mechanism; an automated absorption mechanism provided on the preparation area of workbench and at a side of the weighing mechanism, connected to a control interface and having access to a container in the stir area, and adapted to withdraw redundant liquid; wherein liquid density in a container in the stir area is iteratively adjusted by automatically withdrawing redundant liquid and inputting selected amounts of additional powder and liquid with a selected amount of stirring between successive iterations, until a target value of liquid density is achieved.
