Forward and backward two, side that stay bearing plate 571,572 is separately fixed at main box 511; Forward and backward airbag pressing plate 573,574 is fixed on separately forward and backward on the stay bearing plate 571,572; Two of inside and outside pressing plate 575,576 is connected airbag pressing plate 573,574 with forward and backward respectively movably, so that the parallel sided of inside and outside pressing plate 575,576 and main box 511; Forward and backwardly ballonet 577,578 is folded in forward and backward between airbag pressing plate 573,574 and the inside and outside pressing plate 575,576 respectively, these ballonets 577,578 and atmosphere are communicated with.

Two of inside and outside pressing plate 575,576 is connected airbag pressing plate 573,574 with forward and backward by the folder bag stage clip 579 ' that a folder bag connecting rod 579 and is enclosed within on this folder bag connecting rod 579 respectively.

Press the principle of work of bag reshaping device to be: when the encapsulation bag on the bag transporting body 54 needs shaping, the interior air pressure of vacuum chamber this moment is negative pressure, be higher than the forward and backward pressure that is arranged in vacuum chamber to ballonet 577,578 because of ambient pressure, can make and forward and backward ballonet 577,578 is expanded and promotes inside and outside pressing plate 575,576 and move in opposite directions up to closing up, thereby the bottom of pushing down the encapsulation bag encapsulates the shaping of bag.Guarantee also under the effect of load-transfer device separating device simultaneously that two are transmitted when band separates synchronously, the encapsulation bag is clamped remains on original position, can not fall down.When vacuum chamber recovers normal pressure, forward and backward pressure in the ballonet 577,578 are reduced, inside and outside pressing plate 575,576 is separated under folder bag stage clip 579 ' application force, finish shaping.

See also Fig. 9 more also in conjunction with consulting Fig. 2, folder bag regulating mechanism 58 has quadruplet, is mounted in pairs in two, front and back of the two sides of main box 511 respectively, and is connected with bag transporting body 54 with pressing a bag reshaping device 57.Every cover folder bag regulating mechanism comprises that one regulates adapter plate 581, an adjust bar 582, inboard lock sleeve 583, outside lock sleeve 584 and inner and outer slider 585,586, wherein:

Regulate on adapter plate 581 is connected main box 511 by a lower cantalever 587 the side and with the parallel sided of main box 511; One end of adjust bar 582 be installed in rotation on regulate on the adapter plate 581 and with the lateral vertical of main box 511, the medial segment of the close main box 511 of this adjust bar 582 is provided with sinistral external thread, and is provided with the dextrorotation outside thread away from the segmentum laterale of main box 511; Inboard lock sleeve 583 rotation sets are on the medial segment of adjust bar 582; Outside lock sleeve 584 rotation sets are on the segmentum laterale of adjust bar 582; Inner and outer slider 585,586 is fixed on inboard lock sleeve 583 and the outside lock sleeve 584 by some screws 588 respectively.Along with the rotation of adjust bar 582 make inner and outer slider 585,586 near or separately.

Inner and outer slider 585,586 in the folder bag regulating mechanism 58 is connected with forward and backward two to the inside and outside support wheel adapter plate 541,542 in stay bearing plate 571,572 and the bag transporting body 54 in pressing bag reshaping device 57 by support respectively, is used for regulating the distance between the inside and outside support wheel adapter plate 541,542 in the distance of pressing between bag reshaping device 57 inside and outside pressing plates 575,576 and the bag transporting body 54.Unclamp the fixing screw of slide block and lock sleeve in addition, the rotational lock cover, just the scalable slide block is to the distance between the side of main box 511, and then the scalable distance of pressing bag reshaping device 57 and bag transporting body 54 to arrive between the side of main box.

See also Figure 10 again and in conjunction with consulting Fig. 2, belt conveyor separating mechanism 59 has two covers, lay respectively at the both sides of main box 511 and be installed on the folder bag regulating mechanism 58, and a cover belt conveyor separating mechanism 59 and overlaps bag transporting body 54 and is connected.

Every cover belt conveyor separating mechanism comprises forward and backward cylinder 591,592, forward and backward support 593,594 and forward and backward right angle fagging 595,596, wherein:

Forward and backward cylinder 591,592 is installed on the forward and backward support 593,594 separately; Forward and backward support 593,594 is installed in respectively on a pair of folder bag regulating mechanism 58; The vertical surface of forward and backward right angle fagging 595,596 is connected with the piston rod end of forward and backward cylinder 591,592 respectively, the piston rod end of forward and backward cylinder 591,592 is connected with the vertical surface of forward and backward right angle fagging 595,596 by one dull and stereotyped 597 respectively, and the horizontal surface of forward and backward right angle fagging 595,596 is connected two, front and back of outer support wheel adapter plate 542.

The principle of work of belt conveyor separating mechanism is: when the inside and outside support wheel adapter plate 541,542 of needs clamps, the piston rod of forward and backward cylinder 591,592 stretches out simultaneously, drive moves inward from the outer support wheel adapter plate 542 of main box 511, and clamps with interior support wheel adapter plate 541; When the inside and outside support wheel adapter plate of needs was opened in 541,542 minutes, the piston rod of forward and backward cylinder 591,592 is withdrawn simultaneously, inside and outside support wheel adapter plate was opened in 541,542 minutes, thereby make the synchronous band of transmission on the support wheel 543 not reclamp the encapsulation bag, discharge fully to guarantee the gas in the encapsulation sack.
