The lower end of plate 56 pre-folds briquetting 55 with 2 tops being oppositely arranged respectively and is hinged by first rotating shaft A, and cylinder block 53 is pre-folded at top
It is upper to be hinged by bearing pin and two upper ends of cylinder 8, briquetting 55 is pre-folded at the top of two lower ends of cylinder 8 and two by hinge,
Two cylinders 8 can drive two tops to pre-fold briquetting 55 and be rotated by the center of circle of first rotating shaft A；
As shown in Fig. 2 the bottom forming core membrane module 9 includes briquetting 92 in base angle shaping expansion plate 91 and base angle shaping, bottom
Angle is molded expansion plate 91 and connected with briquetting 92 in the shaping of base angle by guide bearing, and base angle shaping expansion plate 91 pre-folds core with top
Mould hinge seat 51 is fixedly connected, and the lower end that top pre-folds core hinge seat 51 and the first pull bar 3 is hinged, base angle shaping expansion plate 91
It is connected with the upper end of running fix bar 52 by guide bearing, the lower end of running fix bar 52 is fixed on top and pre-folds cylinder block 53
On, top pre-folds core component 5 and is used as guiding up and down motion by running fix bar 52 at work.
The course of work of pre-shaping device at the top of modeling bag box in roof of the present invention：The present invention is broadly divided into 2 processes, and one
Individual is that top pre-folds the pressing of briquetting 55 and the bonding processes of briquetting 92 in the shaping of base angle, and a top pre-folds briquetting 55 and is molded with base angle
The interior opening procedure of briquetting 92.
Top pre-folds the pressing of briquetting 55 and the bonding processes of briquetting 92 in the shaping of base angle：When roof bag 10 arrives position as shown in Figure 1
Put, top pre-folds the in the vertical direction under the driving of corresponding cam link drive device of expansion link 11 and moved downward, and top is pre-
Folding expansion link 11 pulls portable plate 7 synchronously to move downward.On the one hand, it is solid with portable plate 7 to pre-fold the upper end of briquetting connecting plate 56 for top
Fixed connection, lower end pre-fold core 54 with top and are fixedly connected, and top, which pre-folds core 54 and pre-folds briquetting connecting plate 56 with top, to be passed through
Portable plate 7 is moved downwardly to certain position, and passes through because top pre-folds the lower end of briquetting connecting plate 56 and pre-folds briquetting 55 with top
Bearing pin connects, and when top, which pre-folds briquetting connecting plate 56, drops to certain position, top pre-folds briquetting 55 and drops to certain position
While rotated to an angle around first rotating shaft A, the second rotating shaft B, two air inlets of cylinder 8 ensure that top pre-folds briquetting 55 and compressed
With certain thrust when at the top of box.Pre-fold core 54 at top to pre-fold under the collective effect of briquetting 55 with top, top is pre-
For crimping block 55 according to the original rolling line in the top of roof bag 10 by the pre- foldable type in box top, top pre-folds process completion；On the other hand, by
In portable plate 7 is fixedly connected with bearing block 6, the upper and lower side of the second pull bar 4 connects with core lever 2 and bearing block 6 by the way that ball is secondary respectively
Connect, core lever 2 is by portable plate 7 and bearing block 6 around the 3rd rotating shaft C clockwise rotation, the first pull bar 3 and core lever
2 connect by the way that ball is secondary, and the rotary motion of core lever 2 can cause the parallel motion of the first pull bar 3 and the second pull bar 4, i.e., vertical
Moving downward, top pre-folds the upper end of core hinge seat 51 and is hinged with the first pull bar 3, and lower end is hinged with base angle shaping expansion plate 91,
And connected between base angle shaping expansion plate 91 and two running fix bars 52 by guide bearing, so the first pull bar 3 is vertical
Moving downward can cause base angle shaping expansion plate 91 be used as to lead by running fix bar 52 and move downward, base angle be molded in briquetting 92
Be threadably secured and be connected with base angle shaping expansion plate 91, therefore under being molded the vertical promotion of expansion plate 91 at base angle, base angle into
Briquetting 92 is also vertically movable downwards in type arrives certain height, and now, base angle is molded outer briquetting 12 and drives dress by cam link
Put driving base angle shaping expansion link 13 to move straight up, briquetting 92 is synchronous in the base angle outer briquetting 12 of shaping is molded with base angle
Under effect, base angle forming blocks bonding processes are completed.
Top pre-folds briquetting 55 and the opening procedure of briquetting 92 in the shaping of base angle：Top pre-folds expansion link 11 and passes through cam link
Moved upwards in vertical direction under drive device driving, top pre-folds expansion link 14 and pulls the synchronous motion upwards of portable plate 7.One side
Face, 2 tops pre-fold briquetting 55 and rotated to an angle by pre-folding briquetting connecting plate 56 rotating around first rotating shaft A, the second rotating shaft B
Open, while top pre-folds core 54 and moved straight up by portable plate 7, that is, pre-folds briquetting opening, cylinder 8 is deflated, and is unclamped
Tense, reseting procedure is completed；On the other hand, core lever 2 is turned counterclockwise by the second pull bar 4 and bearing block 6 around the 3rd rotating shaft C
Dynamic, briquetting 92 pre-folds core hinge seat 51 by the first pull bar 3 and top and is used as guiding using running fix bar 52 in the shaping of base angle
Move straight up, while base angle is molded outer briquetting 12 and drives base angle shaping expansion link 13 vertical by cam link drive device
Move downward, i.e., the pressing block of briquetting 92 is opened in the shaping of base angle, and base angle shaping reseting procedure is completed.
The present invention during preforming position, first blows roof modeling bag inside with high-temperature hot-air, makes room at the top of roof modeling bag reaches
Top modeling packaging material reaches certain pliability.Then pre-fold core with base angle former and top simultaneously and realize that the top of bag box is moulded on roof
