The invention discloses a negative pressure type quantitative filling machine which comprises a quantitative device, a liquid supply device, a liquid filling device, a vacuumizing device, a liquid delivery device and a rack, wherein the quantitative device is used for containing liquid medicine with certain amount; the liquid supply device is used for providing the liquid medicine for the quantitative device and comprises a liquid supply pipeline and a switching valve for controlling liquid supply; the liquid filling device comprises a filling head for filling the liquid medicine into a medicine bottle, and a sealing piece which is arranged on the filling head and is used for sealing the bottle opening of the medicine bottle during filling; the vacuumizing device is used for vacuumizing the sealed medicine bottle by virtue of the filling device; the liquid delivery device is used for communicating the sealed medicine bottle with the quantitative device by virtue of the liquid filling device; and the rack is used for mounting the quantitative device, the liquid supply device, the liquid filling device and the vacuumizing device. According to the filling machine, the liquid medicine filled into the medicine bottles is equivalent, and the metering difference is very small. The invention also discloses a negative pressure type quantitative filling method with the same or similar characteristics as the negative pressure type quantitative filling machine.
Description
Technical field [0001] The invention relates to the technical field of medical or beverage equipment, in particular to a negative pressure quantitative filling machine and a filling method. The above-mentioned negative pressure quantitative filling machine and filling method are mainly used in filling equipment, and are generally used in the filling of medical liquids. Therefore, it is convenient to describe the present invention in terms of such use or function, but it should be understood that the present invention can be used in alternative medical or beverage filling equipment. Background technique [0002] There are various reliability problems in the filling of medical liquids, one of which is the problem of filling measurement errors. Disadvantageously, various reasons often cause a large error between the amount of the liquid medicine poured into the corresponding packaging container and the calibration volume during the filling of the liquid medicine, which has an adver...
