Bag body 4 can be fixed by connecting band 12；
S9, it carries out folding shaping inspection after installing vent valve, valve port position adds bottom to be put into liner plate by technique ruler
Very little folding pays attention to the position for checking dog-ear, and dog-ear wants smooth, puts magnet positions well, and being put into platform will check whether position is accurate,
It folds whether position has mobile appearance, determines not misunderstand seal and scald, envelope will check the quality that envelope is scalded after scalding, see if there is folding
Position gas leakage；
S10, qualified bag body 4 will be examined to carry out finished product vanning.
In the present invention, in production, the middle envelope of suitable size is placed on station, then choosing need to be to be added
Vent valve obtains the size and size of vent valve, carries out upper bottom by grinding tool centering envelope, using bottom ironing machine carry out pressing, one
Secondary molding cannot be cut out, and the sheet stock of vent valve valve port is positioned using valve port localization machine, is reinforced, is carried out by grinding tool
Mouth covers, and then bottom ironing machine is recycled to carry out pressing, cannot cut out, one-pass molding, by the disposable hot pressure of vent valve valve port at cylinder
Shape, according to the size of vent valve valve port cut in valve port length on envelope, fold after vent valve is installed whole
Shape is examined, and when testing, capping 3 is backed out from connector 1, is then squeezed bag body 4, the air in bag body 4 is squeezed out,
Then capping 3 is screwed on connector 1 again, then qualified bag body 4 will be examined to carry out finished product vanning, is held using bag body 4
When article, connecting band 12 is pulled out out of fixed bin 9, is then wound bag body 4 using connecting band 12, then utilizes connection
With on 12 velcro hook 13 and velcro generatrix 14 be fixed, to improve the fastness of bag body 4.
The foregoing is only a preferred embodiment of the present invention, but scope of protection of the present invention is not limited thereto,
Anyone skilled in the art in the technical scope disclosed by the present invention, according to the technique and scheme of the present invention and its
