As shown in fig. 7, it is roller to fold intensifying device 160, roller is embedded in the burst of packaging bag, is rolled in limitation packaging bag
The position of line C keeps constant.The front and back position of roller can be moved, and adjust the depth of burst.
As shown in figure 5 and figure 7, folding roller arrangement 170 includes：First folding roller 171, the second folding roller 172, folding roller branch
Frame 173 and 2 auxiliary stopper posts 174.Fold roller support 173 be arranged on support 180, fold roller support 173 by with support
Slotted hole connection, regulation before and after position.First folding roller 171 and the second folding roller 172 are symmetrically disposed in folding roller branch
On frame 173, and it is vertically arranged with mobile conveying roller.
First folding roller 171, the second folding roller 172 any one or two synchronizations are motor driven rotation.The present embodiment
In, the rotate counterclockwise of the first folding roller 171, the second folding roller 172 turns clockwise, two folding roller opposite direction rotatings.Folding is in
The packaging bag of " W " type is passed through between the first folding roller 171 and the second folding roller 172, receives both extruding, is completed final
Molding procedure.
2 auxiliary stopper posts 174 are symmetricly set on folding and merge the folding roller 171 of device 150 and first, the second folding roller
Between 172.And 2 centers of auxiliary stopper post 174 and the first folding roller 171, the midline position of the second folding roller 172
Point-blank.Still the first folding roller 171, the second folding roller 172 are parallel for 2 auxiliary stopper posts 174.2 auxiliary stoppers
Post 174 limits the position that packaging bag is advanced, to ensure packaging bag primarily to packaging bag is during folding in both sides
Size as requested is realized folding.2 auxiliary stopper posts 174 are adjustably disposed on support 180.
The method for folding of packaging bag：
Step A:Position adjustments.
Step A-1, the folding for needing the middle polyline pinch roller 135 of middle polyline pressure setting 130, folding merging device 150
Pressure head 153, the roller for folding intensifying device 160, the midline position and the first folding roller 171 of 2 auxiliary stopper posts 174 and the
The midline position of two-fold roller 172 set point-blank, that is, packaging bag middle polyline C position.
The height and position of step A-2, the middle polyline pinch roller 135 for also needing to adjust middle polyline pressure setting 130, adapts to different
Material different-thickness packaging bag, the requirement of center line C indentation.
Step A-3, the mobile conveying roller support 122-1 of regulation and folding merge the distance between support 151.
The end position of broken line gag lever post 141 of step A-4, regulation both sides broken line stopping means 140, alignment packaging bag side folding
The position of line R.
Step A-5, regulation fold the position of the roller of intensifying device 160, and regulation folds the folding roller support of roller arrangement 170
173 front and back position, adapts to the packaging bag of different in width.
Step B, the packaging bag raw material one end that will be placed on discharging device 110 are extracted out, in sequentially passing through roller devices
Each conveying roller.In the process, the right position of side locating part 123 is adjusted, the position of packaging bag raw material side is limited.
After step C, packaging bag raw material pass through the last mobile conveying roller 122-2 of roller devices 120, movement is arranged on
The middle polyline pinch roller 135 of the middle polyline pressure setting 130 on conveying roller 122-2 just extrudes middle polyline C pressures in packaging bag raw material B
Trace.
Step D, packaging bag are subject to the outside power in the end of broken line gag lever post 141, the broken line R turnovers of packaging bag side.
The end that step E, packaging bag are in is folded in " W " type, is limited at coincidence of a folding in embedded folded slot 153-1.
Step F, the burst of " W " the type bottom of packaging bag are passed through from the roller both sides for folding intensifying device 160 respectively.
Step G, complete fold packaging bag from fold roller arrangement 170 the first folding roller 171 and the second folding roller 172 it
Between press through.
The motor of step H, open collapsible roller arrangement 170, drives the first folding roller 171 and the opposite rotation of the second folding roller 172
Turn, discharging device 110 starts blowing.Fully automatically realize that a step folds in " W " type packaging bag.
It should be noted that regulating step A can respectively be adjusted when packaging bag raw material passes through each device for the first time, also
Be say with step B to step G synchronously carry out.
In addition, packaging bag folding apparatus 100 in the present invention by both sides broken lines stopping means 140, fold intensifying device 160
Removal, it is also possible to fold the packaging bag of " V " type, a tractor serves several purposes.
