Abstract
It the utility model is related to a kind of forming template device that can be sealed to the bag body for having sealed valve port.The valve bag forming template device, includes insert edge template, it is characterised in that：The front end of the insert edge template is provided with the wide template of left bag and the wide template of right bag, there is valve port passage between the wide template of left bag and the wide template of right bag, cover plate is provided with above the valve port passage, the cover plate is while be connected in the wide template of left bag, another side is connected in the wide template of right bag, and there is valve port to cross groove for the bottom of the cover plate.While this valve bag forming template device can complete heat-sealing, it can ensure that a bag body trend does not shift, while valve port can be allowed to pass through among template again.
Description
Technical field
It the utility model is related to a kind of bag making device, and in particular to a kind of valve bag forming template device.
Background technology
Valve bag is that one kind seals one-way exhaust valve on the internal wall of bag（Abbreviation valve port）Sack, such as Fig. 3 and Fig. 4 institutes
Show, because equipped with one-way exhaust valve, this sack can allow the internal gas of bag to be discharged, and the air in the external world can not be allowed to enter,
The pack environment of packing material, especially foodstuff packing material are thereby ensured that, in the case of without vacuum packaging, can be extended
Shelf-life.The making of general this sack is completed on Bag Making Machine at present, and its production order is first to seal valve port in bag
On body, bag body as shown in Figure 4 is then formed by insert edge template, then the side of bag body is sealed by heat sealing mechanism
Close, then bottom is sealed, finally bag body is cut, is consequently formed a complete valve bag.Current general bag
The heat sealing mechanism of machine is all to realize to press heat-sealing with unification plane bottom plate, but this heat-sealable way meeting with plane bottom plate
Cause valve port to pass through below template, thus can cause that sack center section can not be sealed.
The content of the invention
In view of the shortcomings of the prior art, can be carried out the invention provides a kind of to the bag body for having sealed valve port
The forming template device of heat-sealing.
The valve bag forming template device, includes insert edge template, it is characterised in that：The front end of the insert edge template is provided with
The left wide template of bag and the wide template of right bag, have valve port passage, the valve port leads between the left wide template of bag and the wide template of right bag
Cover plate is provided with above road, the cover plate is while be connected in the wide template of left bag, and another side is connected in the wide template of right bag, the lid
There is valve port to cross groove for the bottom of plate.
The both sides of the cover plate are all bolted in the wide template of left bag and the wide template of right bag.
The wide template of left bag is also associated with insert edge template simultaneously with the wide template of right bag.
According to valve bag forming template device provided by the invention, pass through the valve between the wide template of left bag and the wide template of right bag
Mouthful passage, allow valve port can be in valve port passage by the way that and cover plate coordinates heat sealing mechanism to complete to seal as bottom plate, so in energy
While enough completion heat-sealings, it can ensure that a bag body trend does not shift, while valve port can be allowed to pass through among template again.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model；
Fig. 2 is along the sectional view in A-A directions in Fig. 1；
Fig. 3 is the front view of valve bag；
Fig. 4 is the side view of valve bag.
Embodiment
As shown in figure 1, this valve bag forming template device includes being connected with insert edge template 1, insert edge template 1 is used for bag body
The shaping of two side edgefolds, form bag body as shown in Figure 4, and be provided with the wide template 2 of left bag in the front end of insert edge template 1 and right bag is wide
Template 3, has a valve port passage 4 between the left wide template 2 of bag and the wide template 3 of right bag, the valve port 7 on bag body 6 is just out of valve port passage 4
By, due to the valve port 7 on continuous bag body 6 all in the valve port passage 4 by therefore ensure that the straight line trend of bag body conveying
Pass through with valve port；And cover plate 5 is provided with above valve port passage 4, the one side of cover plate 5 is connected in the wide template 2 of left bag, and another side connects
It is connected in the wide template 3 of right bag, and there is valve port to cross groove 50 for the bottom of cover plate 5.As shown in Fig. 2 valve port 7 is in valve port passage 4
It is mobile, crossed then into the valve port of cover plate 5 in groove 50, during heat-sealing, heat sealing mechanism coordinates the pressing of cover plate 5 to complete the side of bag body
Envelope, it is consequently formed the edge sealing 61 of sack.
In addition, the both sides of cover plate 5 are all bolted in left bag by the installation of cover plate 5, the utility model for convenience
In wide template 2 and the wide template 3 of right bag.
And in order to adapt to make the sack with two side edgefolds, the utility model is in the wide template 2 of left bag and right bag
The rear end of wide template 3 is connected with insert edge template 1.
