Description

Multi-functional multistation direct-drawing type vacuum nitrogen filling packing machine

The utility model relates to a kind of wrapping machine, refers to a kind of vacuum nitrogen fresh-keeping packaging machine especially.

The fresh-keeping packaging machinery of domestic production at present generally all adopts cavate, promptly adopts vacuum pump that vacuum chamber is vacuumized, and this wrapping machine energy consumption height, efficient are low, and need configuration nitrogen gas cylinder in addition, and not only floor area is big, and cumbersome.Recently, adopt vacuum generator directly packaging bag to be vacuumized though had on the market, and produce the wrapping machine of nitrogen voluntarily, aspect packing technique, remarkable progress has been arranged, but still had some defectives and deficiency.For example package speed is lower, and degree of automation is high not enough, and tape counter not, can not show production quantity automatically, and seal widths is narrower, is not with and seals the date etc.

The purpose of this utility model is to provide a kind of multi-functional multistation direct-drawing type vacuum nitrogen filling packing machine, thereby solve the problem that power consumption height, efficient are low, package speed is lower and degree of automation is not high that the above-mentioned domestic existing fresh-keeping packaging machine of producing exists, and will separate and must not show automatically that output and seal widths are narrow, not with the problem of sealing the date.

The purpose of this utility model reaches by following measure: multi-functional multistation direct-drawing type vacuum nitrogen filling packing machine is made of Rack Body, air accumulator, electromagnetic valve, absorption canister, nitrogen storage tank, vacuum generator and bench board and instrument carrier panel etc.Be provided with a plurality of bench board in the Rack Body front, manual ball valve is equipped with at the Rack Body rear portion, compressed air line by this manual ball valve be contained in Rack Body in-to-in air accumulator and join, the absorption canister that can make the pressurized air that enters become nitrogen also is housed in Rack Body inside and utilizes jet to aspirate the vacuum generator of principle, and nitrogen storage tank and various electromagnetic valve and pressure regulating valve.The whole system operation program is by system controlled by computer, thereby makes seal mechanism nitrogen integrated, and makes workflow: the production process and the replacement process degree of automation of material bag → compress sack → vacuumize → inflated with nitrogen → heat-sealing → cooling → product improve.

The utility model has also increased on instrument carrier panel by micro-processor controlled pulse totalizer, and adopt on each bench board widen on sealing strip, and on sealing strip, be provided with 12 through holes, in these 12 through holes, be equiped with the digital head that shows the date manufactured.

The utility model compared with prior art has following advantage:

1, it is integrated to have realized vacuumizing the nitrogen making machine capper, has reduced energy consumption and floor area, and has multiple function and multiple program is selective:

A fills nitrogen

Start → compress sack → vacuum → fill nitrogen → heat-sealing → cooling

B, vacuum

Start → compress sack → vacuum → heat-sealing → cooling

C, displacement

Start → compress sack → vacuum → vacuum nitrogen → fill nitrogen → heat-sealing → cooling

2, have a plurality of bench board position, package speed is fast, the production efficiency height, and realize system controlled by computer, improved degree of automation.

3, on each bench board, adopt the sealing strip of widening, and be equiped with digital head, make packaging bag enclosing better, and the band date manufactured.

The drawing of accompanying drawing is described as follows:
