Description

Technical Field

[0001] The present application relates to the technical field of filling equipment, and in particular to metering filling equipment for liquid pharmaceuticals. Background Art

[0002] At present, in the production process of chemical preparations, liquid chemicals need to be put into containers and packaged to facilitate subsequent transportation and patient use. At present, when filling liquid drugs into containers, a drug filling machine is usually used to fill the required liquid drugs into the container in a quantitative manner, thereby realizing automated production.

[0003] The utility model with the publication number CN208931707U discloses a liquid medicine quantitative filling machine, including a support frame, the bottom end of which is provided with a positioning seat, which is fixed to a workbench by bolts and nuts; a lifting cylinder is installed on the upper end of the support frame, the output end of the lifting cylinder is fixedly installed on the support frame facing upward, and a positioning shaft rod is fixedly installed on the output end of the lifting cylinder; a lifting frame is provided on the side end of the support frame. The liquid medicine quantitative filling machine works through a servo motor, which drives the threaded rod to rotate, thereby driving the piston to squeeze downward, so that the liquid medicine is discharged to add medicine into the liquid medicine bottle, and the overall structure is simple and easy to operate; the number of revolutions required can be calculated according to the amount of liquid medicine to be added to each bottle of liquid medicine, and the rotation amount of the servo motor can be set to achieve quantitative liquid addition; the overall operation is simple, and quantitative liquid addition is achieved, and the quantitative liquid addition amount can be set.

[0004] The invention with the publication number CN116692138A discloses a quantitative filling device, including: a housing; a steering mechanism, the steering mechanism is vertically arranged on the top wall of the housing, and a transmission shaft is arranged at the output end of the steering mechanism; a quantitative filling cylinder, the quantitative filling cylinder is in two groups, the two groups of quantitative filling cylinders are symmetrically distributed on the transmission shaft, the quantitative filling cylinder is composed of a retractable fixed cylinder and a rotating cylinder, the rotating cylinder is provided with a discharge port, and the top wall of the fixed cylinder and the bottom wall of the rotating cylinder are both provided with a liquid level sensor. The present invention, by setting two groups of quantitative filling cylinders, can be used alternately when filling the cartridge, after the quantitative filling cylinder on one side is replenished with liquid medicine, the quantitative filling cylinder on the other side contacts the cartridge for filling, wherein the internal volume of the quantitative filling cylinder is adjustable, the corresponding volume can be preset in advance, the volume can be automatically adjusted, adapted to different processing scenes, and the quantitative filling cylinder and the cartridge can be synchronously operated for filling.

[0005] Regarding the above-mentioned existing quantitative filling device, the inventor believes that the current filling equipment directly uses a flow valve to measure the volume of the medicine filled into the container. However, during the filling process, the flow valve detects the volume of the liquid and transmits it to the control unit. The control unit then controls the valve to close, which still takes a certain amount of time. At this time, the volume of the medicine finally filled into the container will deviate from the rated standard, thereby affecting the safe use of the medicine; and the filling is performed through the nozzle, and the filling speed is too fast. Too fast a speed can easily cause foam to form in the medicine liquid in the volumetric flask. Excessive foam will increase the volume of the medicine liquid in the volumetric flask, and then cause the medicine liquid to overflow from the volumetric flask, causing pollution.
