[0031] Please refer to figure 1 -2. This embodiment provides a gas mixing device 100 , which includes a plurality of mixing gas tanks 110 , a plurality of gas delivery pipes 120 and a packing box tray 140 .

[0032] Wherein, the plurality of mixing gas tanks 110 are cylindrical as a whole, and both ends are conical. A plurality of mixed gas tanks 110 are closely arranged together in the horizontal direction and vertical direction, and the axes of the multiple mixed gas tanks 110 are parallel to each other, which can effectively improve the compactness of the assembly of multiple mixed gas tanks 110, thereby reducing the The space occupied by multiple mixing gas tanks 110 .

[0033] In order to replenish gas in the mixed gas tank 110 conveniently, in this embodiment, one end of each mixed gas tank 110 is connected with an inflatable tube 150, and a plurality of inflated tubes 150 are all made of plastic hoses, so as to be arranged and installed, and to improve The flexibility...

[0050] This embodiment provides a gas mixing device 100, whose overall structure, working principle and technical effects are basically the same as those of the first embodiment, except that:

[0051] In this embodiment, the solenoid valve 130 on each gas delivery pipe 120 is replaced by a mass flow controller. Mass flow controller, referred to as MFC in English, not only has the function of mass flow meter, but also can automatically control the gas flow, that is, the user can set the flow according to the needs, and the MFC will automatically keep the flow constant at the set value, even if the system Fluctuations in pressure or changes in ambient temperature will not cause it to deviate from the set point. Compared with the solenoid valve 130, its operation is simpler, more convenient and intelligent.

Abstract

A gas mixing device and a modified atmosphere packaging machine belong to the packaging equipment field. The gas mixing device comprises a plurality of mixing gas tanks, a plurality of gas transporting pipes and a packaging box tray; the multiple mixing gas tanks correspond to the multiple gas transporting pipes one by one; the packaging box tray is provided with a plurality of packaging box seal cavities; the packaging seal cavities correspond to the gas transporting pipes one by one; and the two ends of each gas transporting pipe communicate with the corresponding mixing gas tank and the corresponding packaging box seal cavity correspondingly. The modified atmosphere packaging machine comprises a machine cabinet and the gas mixing device; and the multiple mixing gas tanks of the gas mixing device are fixedly arranged in the machine cabinet. According to the gas mixing device and the modified atmosphere packaging machine, the uniformity of gas distributing of each packaging box can be effectively improved, and the quality of the packaging boxes is improved after the packaging boxes are processed; and meanwhile, gas consumption is effectively reduced, gas wasting is avoided, the cost of operation and maintenance is reduced, and the defect of an existing technology is remedied.

Description

technical field [0001] The invention relates to the field of packaging equipment, in particular to a gas mixing device and a modified atmosphere packaging machine. Background technique [0002] Modified atmosphere packaging is also called MAP or CAP in foreign countries, and it is called modified atmosphere packaging or displacement gas packaging and inflatable packaging in China. Commonly used gases are N2, O2, CO2, mixed gas O2+N2 or CO2+N2+O2 (ie MAP). Modified atmosphere packaging technology can be widely used to keep various types of food fresh, prolong the shelf life of food, and enhance the value of food. [0003] Most of the gas distribution systems of existing modified atmosphere packaging equipment adopt the mixed gas supply method, that is, one gas tank supplies gas to multiple packaging boxes at the same time. The structure of this gas distribution system is relatively simple, but there are problems of uneven gas distribution for each packaging box, which affec...
