Description
Technical Field
The invention relates to the technical field of packaging equipment, in particular to a pulling exhaust type air column bag.
Background
In the process of packaging and transporting fragile articles such as liquid crystal display screens, a gas column bag is generally used as a buffer protection device, and during production and manufacture of the gas column bag, two layers of reverse air stop valve films are adhered on the inner wall of each air column strip, when in inflation, air enters the air column strips through the air valve films at two sides, after inflation, the air pressure in the air column strip firmly presses the two air valve films to lock the valves, so that the air can not be discharged through the valves, therefore, the air column bag can not leak air after being inflated, but the inflatable bag with the structure can not exhaust, occupies larger space after being inflated, is inconvenient to store, after receiving goods, people can only prick the gas column bag and throw away the gas column bag, and the gas column bag becomes a disposable consumable, and the gas column bag after pricking can not be recycled by factories, so that not only is great resource waste caused, but also the generated gas column bag garbage can influence the natural environment.
For example, patent No. CN 108408251 a proposes a multi-use two-way air valve and a gas column bag, including a bag body and a multi-use two-way air valve, the two-way air valve includes an upper membrane, a lower membrane and a movable sheet clamped between the two membranes, when inflating, the movable sheet is tightly attached between the two membranes, close the air inlet, when deflating, the two membranes are opened by the rotary movable sheet, thereby exhausting, but the movable sheet is always inserted between the two membranes, can cause influence on the sealing performance of the two-way air valve, reduce the service life of the two-way air valve, all the movable sheets in the gas column bag are connected through two pull ropes, the pulling is poor because the pull ropes are flexible structures, the stability is poor, the rotating effect of the movable sheet driven by the pull ropes is not ideal, and when inflating and exhausting, the air flow can drive the movable sheet.
For example, patent No. CN 206813670U proposes a convenient exhaust gas column bag, including a plurality of outer air chamber films and the gas column that interior gas film hot plastic package formed, it has the breach to open on the gas column, when exhausting, go up the membrane and separate with lower membrane, insert the blast pipe again and exhaust in the check valve, because go up membrane and lower mould and paste in breach department through the non-setting adhesive, the non-setting adhesive receives the influence of environmental factors such as humidity and temperature easily and leads to the stickness to reduce, therefore the sealed fastness of breach is relatively poor, the condition of gas leakage appears after aerifing easily, and the device needs to join in marriage a dedicated blast pipe in addition, the blast pipe pricks the gas column bag easily in the transportation and causes gas leakage, influence the use.
