Description
Technical field
The utility model discloses a kind of air valve that is used for the gas packing bag of special form, belong to the technical field of gas packing bag.
Background technique
Traditional package bag is that several protruding air bag bubbles are set on plastic film chip, and the absorbing buffer function by the air bag bubble prevents that breaking or damaging phenomenon from appearring in transit in article.But in actual applications,, just can't reach the purpose that absorbing cushions, cause breaking or damaging of article easily for bigger vibration or impact load because the absorbing buffer function of air bag bubble is limited in one's ability.In the face of this situation, gas packing bag a kind of package bag of absorbing buffer function better effects if appearred, i.e. on the market.
Shown in accompanying drawing 1,2,3, existing gas packing bag comprise several air chambers 6 by heat-sealing line 5 ' be divided into ', and have a suction port 7 ' intake duct 8 ', this intake duct 8 ' have gas circuit and each air chamber 6 ' be connected; The bag of this gas packing bag by last film 9 ', down film 10 ' and be arranged on film 9 ', time film 10 ' between air valve form, wherein air valve comprise several be spaced and be arranged on upper air valve film 1 ', lower air valve film 2 ' between heat-resisting printing 3 ', and each heat-resisting printing 3 ' lay respectively at intake duct 8 ' with each corresponding gas circuit of air chamber 6 ' be connected on.
As shown in Figure 1, 2, when gas by the suction port 7 of gas packing bag ' charge into, gas can along intake duct 8 ' through heat-resisting printing 3 ', lower air valve film 2 ' between enter each air chamber 6 '.Because heat-resisting printing 3 ' be positioned at intake duct 8 ' with each corresponding gas circuit of air chamber 6 ' be connected on, so can prevent upper air valve film 1 ', lower air valve film 2 ' be attached on together, make gas can be fast by each gas circuit pour into each air chamber 6 '.Each gas circuit pour into each air chamber 6 '.
Shown in Fig. 1,3, when air chamber 6 ' inflation is finished, finish intake operation, the pressurized gas of air chamber 6 ' inside will push upper air valve film 1 ', film 9 ' one sides on lower air valve film 2 ' deflection, and make upper air valve film 1 ', the pressing of lower air valve film 2 ' closely in last film 9 ' on, with each air chamber 6 ' gas circuit sealing, thereby form airtightly, prevent air chamber 6 ' interior escape of gas.
When gas packing bag is finished charge operation, each air chamber 6 ' interior gassy and expansion molding.The space that gas packing bag surrounded of expansion molding forms a holding space, can accommodate and desire to accommodate thing.Accommodate thing be subjected to air chamber 6 ' protection can avoid in transit because of vibration or impact occurring breaking or damaging phenomenon.
As shown in Figure 1, heat-resisting printing 3 ' the upper end also be provided with heat seal point 4 ', and this heat seal point 4 ' be positioned at intake duct 8 ' on.If heat seal point 4 ' be not provided with, then gas packing bag can't be inflated.
Aforesaid gas packing bag in the course of working of reality, because each gas packing bag generally adopts the end at bag to be processed into aforesaid inflator, but in actual applications, such as being in the gas replenishment process of some bigger gas packing bags, an inflator only is set, not only had a strong impact on the speed of inflation, and can cause inflating not exclusively, or when producing more small-sized gas packing bag, unnecessary bag work in-process need cut out it, and can't utilize, so compare waste material by original method processing gas packing bag, finally cause the reduction of gas packing bag manufacturing efficiency, the raising of cost of production, and influence usability.
The model utility content
In order to solve above-mentioned problems of the prior art, it is a kind of simple in structure that the utility model provides, the usability height, and improved aeration speed, improved manufacturing efficiency, the air valve of the gas packing bag that is used for special form that saves production cost.
To achieve these goals, the technological scheme that the utility model adopted is: a kind of air valve that is used for the gas packing bag of special form, comprise that several are spaced and are arranged on the heat-resisting printing on the plastic pellicle of being imprinted between upper air valve film, the lower air valve film, described upper air valve film, the lower air valve film is parallel is symmetrically arranged with 2 pairs, and 2 pairs of upper air valve films, lower air valve films are integrally manufactured.
Described heat-resisting printing runs through and is arranged between 2 pairs of upper air valve films, the lower air valve film, and also is provided with heat-resisting printing between per two adjacent heat-resisting printings.Described 2 pairs of upper air valve films, lower air valve film are arranged on the intermediate portion of gas packing bag bag.This kind is provided with the gas packing bag that air valve is mainly used in bigger shape, can both sides air inlet simultaneously, the admission velocity of accelerating gas makes sack pour into an air chamber rapidly, accelerates aeration speed, and makes inflation more complete.
The described heat-resisting spacing 1-2 centimetre symmetry that is printed as is imprinted on the plastic pellicle, and be respectively arranged with heat-resisting printing between the every pair of upper air valve film, the lower air valve film, also be respectively arranged with heat-resisting printing between per two adjacent heat-resisting printings, and be provided with 2 plastic packaging lines between the 2 pairs of upper air valve films, lower air valve film.The air valve of this kind setting mainly is used in the gas packing bag of smaller shape, and 2 pairs of upper air valve films, lower air valve films are arranged on any position of gas packing bag bag.Can after blocking between 2 pairs of upper air valve films, the lower air valve film,, just can make two sacks of two different sizes according to actual needs as long as through time processing.
The utility model is used for the air valve of the gas packing bag of special form, when producing the gas packing bag of bigger shape, 2 pairs of parallel and upper air valve films that are interconnected, the setting of lower air valve film, the passage that makes air inlet than traditional increase by one times, the air valve that has solved traditional gas packing bag has a strong impact on aeration speed because suction port is few, cause inflating incomplete problem, improved usability.Or when producing the gas packing bag of smaller shape, having solved unnecessary bag work in-process need cut out it, and unserviceable problem, can make 2 pairs of upper air valve films that do not interconnect, lower air valve film at the different parts of bag simultaneously, then after blocking between 2 pairs of upper air valve films, the lower air valve film, become two independently gas packing bags, not only improved manufacturing efficiency, saved cost of production simultaneously.
