Problems solved by technology

The replaced waste engine oil will pollute the environment
The oil and gas discharged by the vacuum pump during the working process will also pollute the workshop and the packaged products.
Because the packaging box completes the gas replacement and product packaging in the vacuum chamber, its complex vacuum chamber structure and the gas path structure requiring high precision will greatly increase the manufacturing cost and the price is expensive
The purchasing power of customers is greatly reduced, which is not conducive to the safe and hygienic production in the field of food and medicine in my country

Embodiment 1

[0074]A fresh-keeping gas replacement device, comprising a positioning mold 101, a pressing plate 102 and a sealing film cutting device 103; the positioning mold 101 is provided with a positioning cavity 104 for placing a packaging box 114, and the positioning mold 101 is also provided with an inlet connecting the positioning cavity 104 The air hole 105 and the exhaust hole 106; the air inlet 105 includes a connected air inlet 107 and an air outlet 108, the air inlet 107 is arranged on the outside of the positioning mold 101, and the air outlet 108 is arranged on the side wall of the positioning cavity 104. There are 6 air outlets 108, and the 6 air outlets 108 are arranged in a "one" shape, and are evenly spaced on one of the side walls of the positioning cavity 104, and the side wall is inclined upward, so that the air outlet 108 is inclined upward. There are also 6 exhaust holes 106, which are evenly spaced on the other side wall of the positioning cavity 104. One end of the...

Embodiment 2

[0078] A fresh-keeping gas replacement method, comprising the steps of:

[0079] The packing box is placed in the positioning cavity 104 of the positioning mold 101, so that the edge of the positioning mold 101 is bonded to the sealing ring 109 in the positioning cavity 104;

[0080] Cover a layer of film 113 on the upper surface of the positioning mold 101;

[0081] The film 113 is pressed on the upper surface of the positioning mold 101 by the pressing plate 102;

[0082] Through the air inlet 105 arranged on the positioning mold 101, fresh-keeping gas is passed into the packaging box, so that the fresh-keeping gas is obliquely entered in the packaging box and forms a vortex-shaped air flow, and the original gas in the packaging box is discharged through the exhaust hole 106;

[0083] The sealing and film cutting mechanism is used to seal and cut the packaging box.

[0084] The fresh-keeping gas replacement device and method obtained through the above design can quickly fe...

Abstract

The invention provides a fresh-keeping gas replacement device and method and belongs to the field of packaging equipment. The fresh-keeping gas replacement device comprises a positioning die, a pressing plate and a sealing film cutting device, wherein a positioning cavity for holding a packaging box is arranged on the positioning die; an air inlet hole and an air outlet hole which are communicated with the positioning cavity are formed in the positioning die; the pressing plate and the sealing film cutting device are connected through an elastic device; holes are formed in the pressing plate; the sealing film cutting device comprises a sealing film cutting mechanism; when the elastic device performs compression, the sealing film cutting mechanism can penetrate through the holes. By means of the fresh-keeping gas replacement device and method, fresh gas can be rapidly fed into the packaging box; a vacuum pump is not required; compared with the prior art, the fresh-keeping gas replacement device and method is more environmentally friendly and economical, higher in replacement accuracy, simple in structure and extremely convenient to maintain, the cost is greatly reduced, the machine purchase cost is also reduced for a user, and the influence on the whole food industry is profound.

Description

technical field [0001] The invention relates to the field of packaging equipment, in particular to a fresh-keeping gas replacement device and method. Background technique [0002] The packaging machine is one of the necessary equipment in the field of food packaging. At present, the more advanced modified atmosphere packaging machines in the market use a vacuum pump to extract the air in the packaging box, and then fill it with freshness and quality preservation gas. This method makes the vacuum pump work frequently, and the oil has to be changed after each working period. The replaced waste engine oil will pollute the environment. The oil and gas discharged by the vacuum pump during the working process will also pollute the workshop and the packaged products. Because the packaging box completes the gas replacement and product packaging in the vacuum chamber, its complex vacuum chamber structure and the gas path structure requiring high precision will greatly increase the ...
