Description
Technical field
The present invention relates to packaging bag production technical field, and in particular to a kind of manufacture method of Double-layer packaging bag.
Background technology
At present, as the continuous development of chemical industry, various chemical raw materials, the production capacity of heavy chemicals have obtained significantly
Improve, correspondingly, the demand of packaging material is constantly expanded, requires also improving constantly.Relatively lived because many chemicals have
Bold and vigorous chemical property, the sealing to packaging material can propose very high requirement, and Double-layer packaging bag is usually used in packing this kind of material,
Such packaging bag uses PP bag films that material sealing is reached to the purpose for obstructing air, outer layer by hot-seal as inner layer bag
Higher intensity is provided using plastic woven cloth or paper and plastics compound bag, protects inner layer bag not damaged and can be printed, be multiple
The operations such as conjunction do not influence the sealing property of inner bag, are a kind of packaged forms being widely used.But the preparation section of double-ply bag is numerous
It is trivial, it is necessary to the consumption of a large amount of human resources.Because the inside and outside bag sack of double-ply bag is sutured by manually, thus bring with
Lower shortcoming：(1) need to fold before inside and outside bag sack suture, so as to cause the waste of raw material, artificial sealing requires alignment folding
Mouth, rotation suture, height, defect rate are high to be required to operation；(2) automaticity is low, and operating efficiency is difficult to improve.
The content of the invention
It is an object of the invention to provide a kind of manufacture method of Double-layer packaging bag, and it advantageously reduces material consumption, and
And bag body flatness is more preferable, while improve automaticity and production efficiency.
To achieve the above object, the present invention provides following technical scheme：
A kind of manufacture method of Double-layer packaging bag, it comprises the following steps：
(1) outer bag is cut：According to bag body length size, using the cutting length required for color sensor automatic identification,
And the outer bag bag body of strip is cut out from braiding cylinder cloth；
(2) inner bag is cut：Fixed length cutting PP or PE film roll cloth, PP the or PE film roll cloth cut are longer than outer bag bag body 10-
20mm, and the inner bag for being longer than outer bag part is folded, that is, obtain strip inner bag；
(3) interior outer bag fit：The outer bag bag body for delivering to inner bag outlet is opened by vacuum chuck device, blowing device is matched somebody with somebody
Close manipulator the inner bag cut feeding outer bag bag is internal, manipulator is arranged alignment, and inner bag sack is put down with external bag opening
Together, inner bag with outer bag bag body is smooth is bonded, there is no bubble between inner bag and outer bag bag body, by inner bag and outer bag bag body sack position
With point gum machine green tack, welded to open the sack of inner bag and outer bag bag body；
(4) inner bag seam bottom：The bag bottom of outer bag bag body and inner bag is sutured using crimping unit, sewing machine, turning into can be straight
It is hinged with the interior outer bag complex of material；
(5) inside and outside sack welding：Into inside and outside sack welding sequence, first using vacuum cup respectively by inner bag, outer bag
Mouth is opened, and manipulator is sent into anti-welding plate at the sack of inner bag, and after sucker is decontroled, interior outer bag complex is sent by anti-welded plate
Onto welding bench, welding bench ultrasonic wave welds external bag opening and inner bag sack by upper and lower faces simultaneously, can be by outside after the several seconds
The inwall of bag sack and the outer wall of inner bag sack are combined together, and are then pumped anti-welding plate, are become the bilayer of shaping
Packaging bag；
(6) arrange：After examining Double-layer packaging bag sealing to have no problem, packing mouth is transported to；
(7) count, pack, can pack and dispatch from the factory after being counted according to production requirement.
Preferably, the PP film roll cloth cut is longer than outer bag bag body 15mm.
Compared with prior art, the beneficial effects of the invention are as follows：
The present invention using ultrasonic wave internally, outer bag seal, compared to Traditional Man sealing, sealing regularity is good, automates journey
Degree is high, improves efficiency, reduces substandard products, requires low to craftsmanship；Ultrasonic bond interface does not have lap, reduces production
Material consumption, the sealing that bag body flatness is more preferable, sealing will not destroy bag body.
Embodiment
