Description
Technical Field
The invention relates to the technical field of film layered products, in particular to a suitable bubble bag and a die thereof.
Background
Products and articles which are fragile and afraid of collision exist in daily life and industrial production, and the products and articles are generally wrapped through a bubble bag or a gas column bag in the prior art so as to provide a buffer protection layer and avoid collision damage.
Among them, for the object with higher protection requirement, the object is usually protected by an inflated bubble bag, which can provide stronger protection and impact buffering effects, for example, the chinese patent publication CN 207060862U discloses a small calabash bubble bag and a mold, which comprises a plurality of calabash-shaped air bags, and can be used as a packaging protection layer for the object.
However, for the bottle gourd bubble bag with a fixed die, the application range is limited, the thickness and the specification of the bubble bag limit the flexibility and the packaging volume of the bubble bag, and for objects with different requirements, the dies with different specifications are needed to produce the bubble bag with adaptability, so that the production cost is high, and the time and the labor are wasted.
Disclosure of Invention
In order to solve the technical problems, the technical scheme of the prior application is improved, and the application aims to provide the applicable bubble bag and the die thereof.
An applicable bubble bag is formed by laminating at least two layers of films, comprising:
Each inflatable belt comprises a plurality of expansion air bags and a contraction air passage which are alternately communicated, and the expansion air bags are communicated with the contraction air passages through communication ports;
the connecting part is arranged between two adjacent inflatable belts and is used as a fusion and fixation structure between the films, and is provided with a plurality of connecting structures with outline adaptation, and each connecting structure is formed by connecting an inflatable air bag on one inflatable belt with a contraction air passage on the other adjacent inflatable belt;
The inflatable parts are respectively arranged at the end parts of the inflatable belts;
the plurality of bending promoting parts are arranged at the expanding air sac and are fusion and fixedly connected structures among the films;
The bending promoting part comprises a strip-shaped first bending surface, and two ends of the first bending surface are respectively pointed to the joint structures at two sides of the inflatable bag where the first bending surface is positioned;
Or alternatively
The bending promoting part comprises a block-shaped second bending surface which at least covers the center of the expansion air bag where the second bending surface is located.
The technical scheme aims at improving the bottle gourd bubble bag so that the bottle gourd bubble bag with the same specification has a better application range, and particularly has better flexibility and thinner use thickness.
Specifically, the maximum resistance limiting the flexibility of the existing cucurbit bubble bag comes from the maximum thickness of the inflated air bags, namely the central position of the inflated air bags, the position is almost inflexible under the action of air pressure filling, and the bending of the existing cucurbit bubble bag is realized mainly through the connecting positions among a plurality of air bags and the edge parts of the air bags which are relatively easy to compress and deform, so that the shape matched with the outer contour of an object is obtained through bending;
Therefore, a bending promoting module is arranged on the bubble bag mould in a targeted manner, and a bending promoting part fixedly connected with the bubble bag through hot melting is formed on the bubble bag;
firstly, the obstruction of the airbag to the bending operation can be reduced;
secondly, the bending promoting part has good bending property and can be used as a bending base;
And the bending promoting part reduces the thickness of the inflated air bag, and is more suitable for objects with higher requirements on the flexibility and the packaging volume.
For the strip-shaped first bending surface, two ends of the first bending surface point to the joint structures on two sides respectively, besides the bending of the joint parts, the first bending surface also provides a bending basis of the other dimension, namely the bending of the bubble bag is realized on the basis of the first bending surface, and the bubble bag is particularly suitable for spherical or similar-shaped objects, and can provide the joint and comprehensive protection;
For the second bending surface of the block shape, the lifting amplitude of the bending performance is smaller than that of the first bending surface, but the air inflation resistance and the air inflation speed are smaller, and the air bubble bag product with slightly poorer coating flexibility and faster air inflation speed can be provided as the supplement of the air bubble bag with the first bending surface.
In order to improve the defect of larger inflation resistance of the first bending surface, as an optimal technical scheme, the first bending surface is formed by a plurality of bending nodes which are arranged at intervals, and a resistance-reducing air inlet hole is formed between the bending nodes.
Further preferably, due to the existence of the resistance-reducing air inlet hole, the action range of the first bending surface can be prolonged as much as possible, and two ends of the first bending surface are respectively connected with two sides of the inner wall of the expansion air bag where the first bending surface is positioned.
For reinforcing the flexibility of the tubular member based on the engagement portion, the bending promoting portion includes a third bending surface having a strip shape, two ends of the third bending surface are respectively directed to two communication ports of the inflatable airbag where the third bending surface is located, and the plurality of third bending surfaces form another bending base outside the engagement portion.
As the bubble bag that the flexibility is strongest, among the preferred technical scheme, first bending surface with the third bending surface exists simultaneously, just first bending surface with the third bending surface constitutes crisscross bending promotion structure on the inflation gasbag, and such bubble bag is particularly useful for the special-shaped article that the volume is less, the structure is more complicated, provides laminating and comprehensive protection as far as possible.
Preferably, the second bending surface is a circular surface with less influence on the inflation resistance.
Preferably, the resistance-reducing air inlet hole is provided with a pore passage with a gradually reduced caliber along the air inlet direction so as to improve the power of air inlet.
Preferably, the width of the first bending surface is not more than 2mm, and the maximum diameter of the second bending surface is not more than 3mm.

In summary, the technical scheme of the invention has the following main beneficial effects:
According to the technical scheme, the bottle gourd bubble bag with the same specification has a better application range by improving the bottle gourd bubble bag, and when the bubble bag is manufactured, the bottle gourd bubble bag with different bending properties can be obtained by only replacing or removing the bending-promoting heat-sealing insert blocks, so that the mould does not need to be manufactured again, the production cost is saved, and the time and the labor are saved.
