Description
Technical field
The present invention relates to bag manufacture field, and in particular to a kind of process for pressing of bag.
Background technology
Bag is had been widely used in daily life, and it can hold various articles, according to what is held
The difference of article, bag can be divided into polytype and style.And during there is the bag of heat insulation function to be exactly numerous bags
One kind, the bag with heat insulation function is generally used for the bag for containing various foods and keeping food temperature and freshness, and it also may be used
For refrigeration, ice cube, cold drink cold items can be such as put into, it has the function of thermal protection cold insulation.
In order to strengthen the heat insulation effect of bag, current insulation is wrapped and is attached using welding mode.Prior art
In in the prior art, manufactured by the way of seamless welding insulation bag processing method it is as follows：
Each sheet material for constituting outer layer is carried out into melting to be formed in the outer indentured of deployed condition；Each sheet material for constituting internal layer is entered
Row melting is formed in the interior indentured of deployed condition；Then by interior indentured upper edge and outer indentured welding, and by interior indentured two
End welding, outer indentured two ends welding makes outer indentured and interior indentured formation frame structure；Then in interior indentured lower end welding
Bottom, it is necessary to set up heat-insulation layer can by heat-insulation layer be put into it is interior indentured and it is outer it is indentured between；Finally carry out outer indentured and outer bottom
Welding works.
When carrying out bag production using the above method, the top-stitching of internal layer and outer layer is attached and carry out again welding shape in framework
Structure, be wrapped inside body and it is outer it is indentured connect into framework when operate more complicated, production efficiency is relatively low.
The content of the invention
Regarding to the issue above, the technical problems to be solved by the invention are to provide a kind of process for pressing of bag, its technique
Simply, it is possible to increase production efficiency.
In order to solve the above technical problems, the technical solution adopted by the present invention is,
A kind of process for pressing of bag, it is comprised the following steps,
Step one, frame structure is formed by outer indentured welding；
Step 2, forms frame structure, and bag bottom is fused into interior indentured lower end by interior indentured welding；
Step 3, frame structure is connected into by heat-insulation layer；
Step 4, will be fused to outer indentured medial surface in the internal layer of frame structure；
Step 5, by heat-insulation layer be placed on internal layer and it is outer it is indentured between, make side heat-insulation layer be interposed in it is interior indentured and it is outer it is indentured it
Between, bottom heat-insulation layer and applied thereto；
Step 6, outer indentured lower end is fused to by outer bottom.
Further, the outer indentured use one piece construction or multiple-piece construction in the step one.
Further, the interior indentured use one piece construction or multiple-piece construction in the step 2.
Further, a step, lateral surface welding reinforced sheet indentured outside were added before the step one.
Further, the step 3 and step 4 are exchanged, step 3, will be fused in the internal layer of frame structure
Outer indentured medial surface；Step 4, frame structure is connected into by heat-insulation layer.
Further, before the step 6 being placed on into step 3 or step 4, first by outer bottom and in frame structure
Internal layer is carried out after outer indentured welding again to be worked with the welding of outer layer.
After adopting the above technical scheme, in the production process of bag, first by the internal layer of bag and the other welding of outsourcing status
Into frame structure, then carry out internal layer and outer indentured welding work, simplify internal layer and it is outer it is indentured between connection work, reduce
The complexity of bag production, improves the productivity ratio of bag.

Specific embodiment
It is the technology contents of the detailed present invention, architectural feature, institute's reached purpose and effect, will below enumerates embodiment and match somebody with somebody
Figure of description is closed to be described in detail.
The invention discloses a kind of process for pressing of bag, wherein, bag is double-decker, including internal layer 3 and outer layer 1,
A heat-insulation layer 2 can be set up between internal layer 3 and outer layer 1.Internal layer 3 includes interior indentured 31 and interior bottom 32, and outer layer 1 includes outer indentured
11 and outer bottom 12, heat-insulation layer 2 includes side heat-insulation layer 21 and bottom heat-insulation layer 22.
A kind of process for pressing of bag disclosed by the invention is comprised the following steps,
Step one, outer indentured the 11 of outer layer 1 left and right two ends are welded together, and make outer indentured 11 to form frame structure；
Step 2, in internal layer 3 indentured 31 left and right two ends are welded together, and the interior bottom 32 of internal layer 3 is fused into interior bag
The lower end of body 31, makes internal layer 3 form the frame structure with bottom；
Step 3, the left and right two ends of sidepiece heat-insulation layer 21 are linked together, and bottom heat-insulation layer 22 is connected into sidepiece heat-insulation layer
21 lower end, so that heat-insulation layer 2 forms a frame structure；
Step 4, outer indentured 11 medial surface is fused to by mould by the upper edge of internal layer 3, is made in the internal layer 3 of frame structure
Linked together with outer indentured the 11 of frame structure；
Step 5, will be placed between internal layer 3 and outer indentured 11 in the heat-insulation layer 2 of frame structure, make bottom heat-insulation layer 22 in interior
Fit at bottom 32；
Step 6, welding is carried out by mould by outer indentured 11 with outer bottom 12, so that forming one has good sealing property and insulation
The bag of effect.
Above-mentioned steps three and step 4 can be exchanged, i.e., welding work of the internal layer 3 with outer indentured 11 is completed in step 3
Make, the connection work of heat-insulation layer 2 is completed in step 4, make heat-insulation layer 2 be in frame structure.
In above-mentioned steps, before step 6 being placed on into step 3 or step 4, that is to say, that first by outer bottom with
After in the outer indentured welding of frame structure, then the welding work for carrying out internal layer and outer layer.
The use of bag for convenience, outside indentured 11 lateral surface can set up reinforced sheet 4, the reinforced sheet 4 can even
Connect handle strip, it is also possible to connect brace, the pocket that placing articles can also be formed with outer indentured 11.It is before step one, i.e., outer
Reinforced sheet 4 can be fused to outer indentured 11 lateral surface by indentured 11 welding before forming frame structure.
Above-mentioned outer indentured 11 and interior indentured 31 can be formed using polylith sheet material welding, it would however also be possible to employ one piece construction.
During using polylith sheet material welding, polylith sheet material is first fused into one piece construction, is then in by outer indentured 11 and the welding of internal layer 3 again
Frame structure.
It is of the invention it is critical that in the production process of bag, first by the internal layer 3 of bag and outer indentured 11 difference welding
Into frame structure, then carry out internal layer 3 and worked with outer indentured 11 welding, simplify the connection work between internal layer 3 and outer indentured 11
Make, reduce the complexity of bag production, improve the productivity ratio of bag.
The above, is only the embodiment of the present invention, and not technical scope of the invention is imposed any restrictions, therefore every
Any trickle amendment, equivalent variations and the modification made to above example according to technical spirit of the invention, still fall within this
In the range of inventive technique scheme.
