A packing machine with nitrogen filling device

Abstract

The invention discloses a racking machine with a nitrogen charging device. The racking machine is applied to pharmacy workshops and comprises a rotary capping machine and the nitrogen charging device corresponding to the rotary capping machine. The nitrogen charging device comprises an arc nitrogen seal part and a nitrogen charging semicircular ring, the arc nitrogen seal part is internally provided with a gas chamber communicated with two gas inlets I connected with a nitrogen source, the arc nitrogen seal part is uniformly provided with a plurality of gas outlets I communicated with the gas chamber, and a retaining curtain is arranged on an outer arc face of the arc nitrogen seal part; the nitrogen charging semicircular ring comprises a semicircular ring bent pipe section and a straight pipe section, the outer arc face of the semicircular ring bent pipe section is uniformly provided with a plurality of gas outlets II, and the nitrogen charging semicircular ring is communicated with the nitrogen source through a gas inlet I on the straight pipe section. Nitrogen is filled into bottles by two nitrogen charging systems, so that nitrogen charging efficiency is higher and nitrogen charging time is shorter; owing to the retaining curtain, remaining oxygen content in penicillin bottles is effectively reduced to less than one percent, and accordingly medicine storage time is prolonged.

Description

technical field [0001] The invention relates to a nitrogen filling device for a medicine dispensing machine, in particular to a nitrogen filling device for a dispensing machine in a pharmaceutical workshop. Background technique [0002] In the pharmaceutical preparation workshop, in order to prevent the deterioration of the pharmaceuticals that are easy to absorb moisture and oxidation, or to prolong the shelf life of the pharmaceuticals, some pharmaceuticals must be protected with nitrogen to isolate oxygen. Therefore, it is necessary to fill the packaging of the pharmaceuticals with nitrogen. When pouring into the medicine bottle, it is necessary to cover it in time to prevent the nitrogen filled in the bottle from overflowing, so the nitrogen charging device is often used in conjunction with the filling machine. Use the existing nitrogen filling equipment to fill the medicine with nitrogen, such as the capping nitrogen filling device disclosed in the invention patent CN18...

AI Technical Summary

Problems solved by technology

Use the existing nitrogen filling equipment to fill the medicine with nitrogen, such as the capping nitrogen filling device disclosed in the invention patent CN1863728A, which is also a capping device with nitrogen filling function. There is only a dispensing nozzle above the bottle to be filled, and the dispensing nozzle is connected Nitrogen source, the bottle is filled with nitrogen as the rotation drives the turret to move forward. The nitrogen filling and capping operations are carried out under the condition that the external environment is air. Since the density of nitrogen is lower than that of air, nitrogen is lighter than air. The nitrogen in the medicine bottle will overflow from the bottle in the air atmosphere, and the oxygen in the air will enter the medicine bottle. After adding the cork, the oxygen content of the nitrogen in the bottle is about 4%. When the content is 4%, it is very easy to change the color level, making the quality of the drug unable to be guaranteed
