Description
Technical field
The present invention relates to a kind of wrapping machine, particularly relate to a kind of gas-control packing device.
Background technology
Gas-control packing device is the foods packing machine of application composite gas displacement fresh-keeping package technology.The principle of controlled atmospheric packing adopts fresh-keeping miscellaneous gas (multiple gases mixes by material characteristic proportioning to be packaged), replace the air in packing box or packaging bag, to change package the external environment condition of material in device, reach anti-bacteria, microbial growth procreation, slow down the rate of metabolism of material, thus extend freshness date or the shelf life of material.So the fresh-keeping packaging at present in the fields such as food all develops into controlled atmospheric packing gradually by vacuum packaging, also air in other fresh-keeping or gas replacement material package of guaranteeing the quality namely is utilized, controlled atmospheric packing has a lot of traditional vacuum and packs incomparable advantage, its gas replacement rate is high, capacity rating is higher, but current gas-control packing device structurally also exists some areas for improvement.
Transmission device due to gas-control packing device has needed vacuum chamber folding, film seal, the necessary action of useless membranectomy three, and traditional transmission device has two kinds of settling modes:
The first, utilize Air compressor as propulsion source, output squeezing air, and band dynamic air cylinder realizes vacuum chamber folding, film seal, the actions such as useless membranectomy.Its shortcoming is that the installation requirement of Air compressor is very high, and must be that technical professional could install, and it takes up room greatly, and in use can cause larger noise pollution, potential safety hazard be also larger, and cost is high;
The second, utilize motor as propulsion source, thus realize vacuum chamber folding, film seal, the necessary action of useless membranectomy etc. three, but its defect at least must will use two motors could realize sealing, cut film and vacuum chamber folding etc., so just cause gas-control packing device volume to increase, structure is very complicated, and cost is high, and maintenance is also inconvenient.
In sum, taking up room of existing gas-control packing device is all larger, and structure is more complicated also, and in use also easily produces noise pollution, and potential safety hazard is large, and cost is high, and maintenance is very inconvenience also.
Summary of the invention
The technical problem to be solved in the present invention is for gas-control packing device safety requirements in prior art high, take up room large, complex structure, and the noise pollution produced in its use procedure is large and high in cost of production defect, provide that a kind of structure is simple, stable working, safety factor are high, cost is low and the simpler gas-control packing device of maintenance.
The technical solution adopted for the present invention to solve the technical problems is: a kind of gas-control packing device comprises frame, cylinder body, pressing plate, depression bar, upper vacuum chamber and lower vacuum chamber, and cylinder body, pressing plate, depression bar, upper vacuum chamber and lower vacuum chamber are placed in frame;
Cylinder body comprises cover plate, upper piston, piston rod, lower piston and cylinder cap;
