Description
Technical field
The present invention relates to a kind of wrapping machine, relate in particular to a kind of gas-control packing device.
Background technology
Gas-control packing device is the foods packing machine of using composite gas displacement fresh-keeping package technology.The principle of controlled atmospheric packing is to adopt fresh-keeping miscellaneous gas (multiple gases is mixed by material characteristic proportioning to be packaged), air in displacement packing box or the packaging bag, the change package external environment condition of material in the device, reach anti-bacteria, microbial growth procreation, slow down the rate of metabolism of material, thereby prolong freshness date or the shelf life of material.So the fresh-keeping packaging in the fields such as food all develops into controlled atmospheric packing by vacuum packaging gradually at present, also namely utilize other fresh-keeping or interior air of the gas replacement material package of guaranteeing the quality, controlled atmospheric packing has the incomparable advantage of a lot of traditional vacuum packings, its gas replacement rate is high, capacity rating is higher, but structurally also there is the improved place of some needs in present gas-control packing device.
Because the transmission device of gas-control packing device need to be finished the vacuum chamber folding, film seal, three of useless membranectomies must move, and traditional transmission device has two kinds of settling modes:
The first utilizes Air compressor as propulsion source, the output squeezing air, and the band dynamic air cylinder is realized the vacuum chamber folding, film seal, the actions such as useless membranectomy.Its shortcoming is that the installation requirement of Air compressor is very high, must be that the technical professional could install, and it takes up room greatly, and in use can cause larger noise pollution, and potential safety hazard is also larger, and cost is high;
The second, utilize motor as propulsion source, thereby realize the vacuum chamber folding, film seal, three of useless membranectomies etc. must move, but its defective is must will use at least two motors could realize sealing, cut film and vacuum chamber folding etc., so just caused the 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 produces easily 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 the prior art high, it is large to take up room, complex structure, and the noise pollution that produces in its use procedure is large and the high in cost of production defective, provides a kind of simple in structure, stable working, safety factor is 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 place in the frame;
Cylinder body comprises cover plate, upper piston, piston rod, lower piston and cylinder cap;
