Auxiliary, Lai Zucheng more preferably connection structure.Each technical characteristic in the invention, under the premise of not conflicting conflict
It can be with combination of interactions.
Referring to figs. 1 to Fig. 3, this is the embodiment of the present invention, specifically:
Air inlet including being sequentially communicated is intubated 111, air inlet pipeline 112, nitrogen cylinder 113, and the air inlet pipeline 112 is equipped with
Intake valve 114 further includes that interconnected pumping is intubated 121, exhaust pipe 122, and the exhaust pipe 122 is equipped with extraction valve
123, further include mounting rack 130, air inlet intubation 111, pumping intubation 121 with the mounting rack 130 in the up-down direction
It is slidably connected.
It is protruded into packaging bag in use, air inlet is intubated 111, pumping intubation 121, opens extraction valve 123 for packaging bag
It vacuumizes, after reaching certain vacuum degree, opens intake valve 114 and start inflated with nitrogen, inflated with nitrogen closes extraction valve after a certain period of time
123, then certain time is waited, when nitrogen charging tolerance is certain, intake valve 114 is closed, air inlet is then intubated 111, pumping intubation 121
It is removed from packaging bag, carries out subsequent envelope movement.The structure of the application is simple, and control is simple, it is only necessary to control pumping
The opening and closing of valve 123 and intake valve 114, by the opening time point of intake valve 114 be arranged in extraction valve 123 shut-in time point it
Before, air inlet can be intubated air originally remaining in 111 and pumped, it is good to take out air effect.
Further, the mounting rack 130 be equipped with the first cylinder 131, the second cylinder 132, first cylinder 131,
The output end of second cylinder 132 is connected with air inlet intubation 111, pumping intubation 121 respectively.Such setting can be controlled separately
Air inlet intubation 111, pumping intubation 121 move up and down, and adjust the difference in height of the lower end of air inlet intubation 111, pumping intubation 121, into
Gas intubation 111, the height of lower end of pumping intubation 121 can be the same or different, can from the different parts of packaging bag into
Row vacuumizes and inflated with nitrogen, in general, vacuumizing from top, from lower part inflated with nitrogen, the effect of air-discharging is best.
Further, the lower end of the air inlet intubation 111 is set to the lower section of the pumping intubation 121.From the upper of packaging bag
Portion vacuumizes, and lower part flows to from the bottom up into nitrogen, packaging bag interior air-flow, and air is squeezed out packaging bag from lower part by nitrogen, emptying
Nitrogen charging effect is more preferable.
Optionally, the cross section that the air inlet is intubated 111, pumping intubation 121 is sector, and the air inlet intubation 111 is taken out
Gas intubation 121 includes flat side wall and arc side wall, the flat side of the flat side wall of the air inlet intubation 111 and the pumping intubation 121
Wall abuts.In this way, being not easy gas leakage between air inlet intubation 111, pumping intubation 121, air inlet intubation 111, pumping intubation 121 are whole
Shape and a root cutting tubing seemingly, bag-clamping mechanism in the prior art can be directly used cooperatively with the nitrogen charging device of the application,
Without being intubated gas leakage in 121 gap from packaging bag and air inlet intubation 111, pumping.
Optionally, the mounting rack 130 is equipped with installation through-hole, and the air inlet intubation 111, pumping intubation 121 are set to
In the installation through-hole, the air inlet intubation 111, pumping intubation 121 are slidably connected with the installation through-hole.Installation through-hole is protected
The stabilization for having demonstrate,proved the relative position of air inlet intubation 111, pumping intubation 121 avoids sending out between air inlet intubation 111, pumping intubation 121
Raw lateral mutual sliding.
A kind of sealing machine further includes bag openning body, cutting agency 3, bag-clamping mechanism, heat-sealing including the nitrogen charging device
Mechanism.
After bag openning body opens packaging bag, blanking is carried out with cutting agency 3, and the air inlet in nitrogen charging mechanism is intubated
111, in the 121 insertion packaging bag of pumping intubation, after the completion of blanking, the oral area of packaging bag is clamped with bag-clamping mechanism and air inlet is intubated
111, pumping intubation 121, is vacuumized and inflated with nitrogen, after the completion of inflated with nitrogen, original position is retracted by nitrogen charging mechanism, uses heat sealing machine
Structure is clamped packaging bag oral area and is sealed, and bag-clamping mechanism retracts original position, and the nitrogen charging and sealing of packaging bag can be completed.
Further, the bag openning body includes sucker 21 and opens bag cylinder 22, and the cutting agency 3 opens bag set on described
Above mechanism, the nitrogen charging device is set to 3 side of cutting agency, and the bag-clamping mechanism includes nip rolls 41 and folder bag cylinder
42, the heat sealing mechanism heating roller 51, heat seal cylinder 52, the sucker 21, nip rolls 41, the setting of 51 vertical array of heating roller.It should
In technical solution, each mechanism structure is compact, takes up space small.
The nip rolls 41 is equipped with elastic layer.Elastic layer can according to air inlet be intubated 111, pumping intubation 121 shape and
Deformation avoids air inlet intubation 111, pumping intubation 121 from being clamped and cause gas that can not circulate.
Better embodiment of the invention is illustrated above, but the invention is not limited to the implementation
