Abstract
The utility model provides an inflatable shim air valve. Each of charging cylinders of an inflatable shim is provided with an independent air inlet. All of the air inlets are arranged in an inlet channel. A one-way valve is arranged at the air inlet of each of the charging cylinders. The non-return valve comprises one layer or a plurality of layers of air valve films parallel with an outer film of the inflatable shim. A heat resisting and insulating layer is sprayed on an air valve film adjacent to an outer film of the inflatable shim, and the surface of the air valve film towards the outer film. Netty thermocompression points, through which an upper air valve film and a lower air valve film adhere to an outer film of another inflatable shim are arranged in the area of the heat resisting and insulating layer. The utility model completely separates one of the two layers of air valve films from the outer film of the inflatable shim through the heat resisting and insulating layer by adopting the simple art that the film surface is sprayed with the heat resisting and insulating layer to achieve hot compacting of the inflatable shim all at once. Accordingly, the manufacturing engineering and the production efficiency are improved by a plurality of times; the cost of goods manufactured is reduced.
Description
Technical field
The utility model relates to a kind of wrapper, particularly relates to a kind of air valve that is used in inflatable gasket or the gas flushing pouch.
Prior art
The current packaging packing has corrugated paper and bubble plastic film, and gas flushing pouch.In existing gas flushing pouch, the inflation bumper bag that is provided has all been used a kind of unidirectional gas charging valve, the structure of this gas charging valve is: this air bag is divided into independently inflator pump of some gas circuits, suction port at each inflator pump is provided with the two-layer air valve film parallel with plastic pellicle, because film has pliability, when inflation, external pressure is higher than the air pressure in the bumper bag inflator pump, two-layer air valve film is blown open, and gas can enter in the inflator pump smoothly; After inflation finishes, the tube internal air pressure is higher than external pressure, and gas flushing pouch expands because of inflation, near the suction port barrel (promptly constituting the two layers of plastic thin films of gas flushing pouch) no longer is parallel double-layer films, but the drum ovalisation, two-layer air valve film is pressed to barrel by air pressure inside, and crooked jam-packed, thereby the sealing suction port reaches and prevents the effect of leaking gas.When this unidirectional gas charging valve can guarantee that damaged gas leakage takes place for single inflator pump, still keep inflated shapes in other inflator pumps, can not cause devastating impact the shockproof effect of whole air bag.
In order further to simplify technology, improve airtight effect, some gas flushing pouch is made into whole and during across whole gas flushing pouch width at the air valve film, at the air valve place weblike heat printing points is set, with certain outer membrane heat-sealing of upper air valve film, lower air valve film and air bag, finish the back unification along the one side inwall bending of inflator pump outer membrane in inflation to guide two-layer air valve film.Yet the manufacturing process of this air bag when hot-forming be more complicated still, needs hot-forming at twice.That is: all cause adhesion for fear of air valve film and two-layer air bag outer membrane, at first upper and lower air valve film and individual layer air bag outer membrane to be carried out mesh point hot pressing, and then another outer membrane of this three-layer thin-film and air bag carried out overall thermocompression forming, like this, completing of whole air bag need be carried out twice repetition stone and start the thermoforming machine twice, is unfavorable for fabricating cost is reduced to bottom line.
Summary of the invention
In view of this, the purpose of this utility model is to provide a kind of new inflatable gasket air valve.It adopts the technology that sprays heat-resisting barrier layer in single face air valve thin film exterior layer, guarantees that air valve film and inflatable gasket film are once hot-forming, and simplified manufacturing technique is enhanced productivity.
For achieving the above object, the technical solution of the utility model is: described inflatable gasket is formed by thermo-compression bonding sealing around the two layers of plastic thin films, also be provided with some shielding wires in the middle of the enclosed edge all around, double-layer films hot pressing on this shielding wire is fixed, this inflatable gasket is divided into independently inflator pump of some air chambers, each inflator pump is respectively equipped with independently suction port, and all suction ports all are located in the common gas-entered passageway, is provided with one-way cock in the suction port position of each inflator pump; This one-way valve comprises that one or more layers is clipped between the two-layer inflatable gasket outer membrane and parallel with it air valve film, on the air valve film adjacent, be coated with heat-resisting barrier layer, in this heat-resisting barrier layer zone, be provided with the weblike heat pressure point that upper and lower air valve film and another inflatable gasket outer membrane are bonded together towards the air valve film surface of this outer membrane with the inflatable gasket outer membrane.
Air valve of the present utility model is by spraying the such relative simple technology of heat-resisting barrier layer at single face air valve film outer surface, one deck in the two-layer air valve film is kept apart fully by heat-resisting barrier layer and inflatable gasket outer membrane, when air cushion is hot-forming, when stone, just upper and lower air valve film can be sandwiched between the upper and lower inflatable gasket outer membrane, finish shielding wire hot pressing between edge sealing hot pressing, the inflator pump simultaneously and the air valve film is hot-forming with the mesh point of the individual layer air cushion outer membrane that does not have heat-resisting barrier layer to isolate through hotpress.Therefore manufacturing process and manufacturing efficiency have all obtained to increase exponentially, and have reduced labour cost and expenses such as machine loss, electric energy, have further reduced cost of goods manufactured.
