The course of work of the present utility model is described as follows（Referring to Fig. 9-Figure 17）：

1st, the folded polybag A after the station of blurting out of Bag Making Machine will blurt out is from front to back（That is in Fig. 9-Figure 17 from left to right） It is sent to above anterior angle folded sheet 10 of the present utility model, trapezoidal preceding folded plate 41, lifting supporting plate 3 and rear folded plate 5（Such as in Fig. 9 pairs Shown in chain-dotted line）；Lifting supporting plate 3 now is located at highest order（The height of slightly below trapezoidal preceding folded plate 41 and rear folded plate 5.

2nd, pressing plate 6 moves forward under the driving of pressing plate drive cylinder 9, while makes pressing plate under the driving of oscillating cylinder 18 6 are upturned, and when reaching polybag A top, pressing plate 6 is downwardly against polybag A（As shown in Figure 10）；

3rd, an anterior angle folded sheet 10 is flipped up 180 °, and then another anterior angle folded sheet 10 is also flipped up 180 °, Two anterior Strap portions of polybag A are folded into middle part respectively（As shown in Figure 10 and Figure 11）；

4th, bag pressing hook 11 is turned over about 170 ° upwards, and polybag A anteriomedial is pushed down after the upset of its front end, Exactly the polybag A just folded two suspender belts are pushed down（As shown in figure 11）, latter two right anterior angle folded sheet 10 resets（Such as Shown in Figure 12）；Then, pressing plate 6 leaves polybag A resets（As shown in figure 13）；

5th, the trapezoidal front end of preceding folded plate 41 is flipped up 180 °, continues upwards to fold back current polybag A front portion Once（As shown in figure 14）.The impression bar 13 of the trapezoidal front end of preceding folded plate 41 is just pressed in above the back of lifting supporting plate 3 at this moment Polybag at, extrude a transverse direction impression（Fold line）.Meanwhile supporting plate 3 is lifted under the driving of small size lift cylinder 22 Move down a less amplitude（About 20-30mm）, positioned at a secondary high position.It is flipped up about in the trapezoidal preceding front end of folded plate 41 At 150 °, the approximated position sensor 40 of swing component 39 on preceding folded plate axle 2, the latter sends signal to the controller of complete machine, control Device control bag pressing hook 11 resets.The opportunity of reset does not stop that the folding of trapezoidal preceding folded plate 41 is defined by bag pressing hook 11）, according to Need the position of throttle position sensor 40.

6th, 180 ° of the upward collapsed forward of rear folded plate 5, the impression that polybag A rear portion extrudes along impression bar 13 is folded one It is secondary, it is seen then that to have the impression, polybag folds more easily along impression, prevents occurring arching upward upwards at fold line when folding Or occur folding irregular phenomenon, this is advantageous to the folding of polybag A rear portions upwards forward（As shown in Figure 15 and Figure 16）.This When polybag A folding be fully completed（If the embodiment shown in Fig. 6, also once to fold）.

7th, lifting supporting plate 3 drops to lowest order（Height slightly below above transmission belt 7）, the polybag A folded falls In transmission belt 7, as transmission belt 7 moves backward to lower step process（As shown in figure 17）.Complete the whole work process folded.
