In force, first the woven bag in stacked state cut is placed on woven bag stacking platform 201, will be cut out
It cuts and the hot inner membrance in stacked state is placed on inner membrance stacking platform 701.
The first step：Lifter plate 302 declines and contacts woven bag, and vacuum device used 601 start air-breathing, after woven bag is sucked
Lifter plate 302 rises to the position higher than the conveyer belt 309 in conveying mechanism 4, whole along braiding under the driving of motor 1
The direction movement of bag width, after reaching designated position, vacuum device used 601 stop suction, and woven bag is fallen, and lifter plate 302 is in electricity
Backhaul under the driving of machine 1.In this way, a woven bag is just placed on conveyer belt 309, position at this time is known as woven bag etc.
Wait for station 9.
Second step：Conveyer belt 309 moves a certain distance woven bag under the drive of motor and reaches woven bag set inner membrance work
Position 10, at this time upper vacuum device used 502 and under vacuum device used 503 start simultaneously at air-breathing, under vacuum device used 503 woven bag lower layer is inhaled
Firmly, open cylinder 501 is released downwards, is retracted after woven bag upper layer is sucked, and so just opens the sack of a woven bag.When opening
When implication cylinder 501 is released downwards, vacuum device used 601 on pivoted arm 607 freely turn under contact and an inner membrance hot bottom be sucked
One end, when open cylinder 501 is retracted upwards, at the same by push rocking arm 104 without slot 101 one end pushing, in this process
In, it pushes rocking arm 104 and touches the magnetic material 608 being fixed on 607 one end of pivoted arm and be depressed into horizontal position, that is,
It is raised to horizontal position being fixed on vacuum device used the 601 of 607 other end of pivoted arm, that is, the one end at inner membrance hot bottom is lifted
Horizontal position is played, this horizontal position is just between the woven bag upper layer being open and lower layer.
Third walks：Inner membrance releases suspension bar 603 and inner membrance is dragged in forward the braiding being open under the driving of motor 3 605
In bag, this distance being dragged in is controlled by PLC, and after reaching specified distance, vacuum device used 601 on pivoted arm 607 stop suction,
Inner membrance is decontroled, after inner membrance is freely fallen, inner membrance releases suspension bar 603, and volume is exited in movement backward under the driving of motor 3 605
It knits bag and returns to original position.
4th step：Released after suspension bar 603 exits woven bag in inner membrance, upper vacuum device used 502 and under it is vacuum device used 503 same
When stop suction, woven bag sack is closed, at this point, conveying mechanism 4 acts, set inner membrance will be completed in conveyer belt 309 thereon
Woven bag is sent to the working range for making bar 801, while the woven bag in woven bag waiting station 9 is sent into woven bag and covers inner membrance
Station 10.The woven bag that set inner membrance is completed is known as finished bag.At this point, the perpendicular placement status of finished bag, makes bar 801 by vertical
Position turns to horizontal position, the woven bag that set inner membrance is completed namely finished bag is laid, and heap is folded.So far, a volume
It knits bag and completes set inner membrance work.
To sum up, i.e. in the cycle first step to the 4th step when woven bag covers inner membrance machine normal work automatically.Because being provided with connection
Dynamic device 100, pivoted arm 607 thereon are in heeling condition when drawing inner membrance, horizontality are in when covering inner membrance so that both
Most last layer inner membrance can be removed on the inner membrance that heap is folded, and inner membrance is released into suspension bar 603 and inhales the one end for putting inner membrance vertical
Histogram it is upward be sized for as small as possible, the bottom of woven bag is extend into when covering inner membrance convenient for it in this way.Again because of setting
Woven bag waiting station 9 and woven bag set inner membrance station 10 so that the first step can be with second step to the in recycling at one
Four step concurrent workings, improve the working efficiency of machine in this way.As woven bag in heaps and inner membrance in heaps gradually complete set
Inner membrance work becomes finished bag, and the height of their most last layers is gradually reduced, then, driving mechanism 1 and driving mechanism two
Woven bag stacking platform 201 and inner membrance stacking platform 701 are raised to position appropriate by 702 respectively under the control of PLC, in this way
Can with time processing 500 or more and midway does not have to again by being manually placed into woven bag and interior film raw material.
The basic principles and main features and advantage of the utility model have been shown and described above.The implementation of the utility model
What example was announced is preferred embodiment, and however, it is not limited to this, those skilled in the art, easily according to above-mentioned implementation
Example, understands the spirit of the utility model, and make different amplification and variation, but as long as not departing from the spirit of the utility model,
It is all within the protection scope of the present utility model.
