Embodiment 1

[0025] see Figure 1-2 , an air column bag of a co-extruded film air-tight and air-tight airtight body, comprising an outer jacket 1 and an interface device 2 provided on the outer jacket 1, the interface device 2 includes a wall cover 21, the wall cover 21 is connected with the outer cover 1, and the wall cover 21 is internally connected There is a connecting sleeve 28 extending to the inside of the jacket 1, the wall sleeve 21 is provided with a first sealing cone sleeve 24, the outer surface of the connecting sleeve 28 is in contact with the inner wall of the first sealing cone sleeve 24, and the inner wall of the wall sleeve 21 is slidingly connected with The extrusion device 4 includes a push ring 44 , which slides on the inner wall of the extrusion device 4 , and the axial movement of the push ring 44 compresses the first sealing taper sleeve 24 to be deformed so as to seal the connecting sleeve 28 .

[0026] In this embodiment: through the inflatable nozzle inserted int...

Embodiment 2

[0028] This embodiment is an improvement made on the basis of Embodiment 1. The push ring 44 is connected to the locking device 3, and the inner wall of the wall sleeve 21 is provided with a first squeeze pad 22 at a position close to the first sealing taper sleeve 24. An extrusion pad 22 is in contact with the outside of the first sealing taper sleeve 24, and the push ring 44 is in contact with the outside of the first extrusion pad 22, and the axial movement of the push ring 44 squeezes the first extrusion pad 22 and the first seal. The taper sleeve 24 is deformed to seal the connection sleeve 28;

[0029]The inner wall of the wall sleeve 21 is provided with a conveying sleeve 26 near the position of the connecting sleeve 28, the conveying sleeve 26 is provided with a second extrusion pad 25, the connecting sleeve 28 is provided with a second sealing taper sleeve 27, and the second sealing taper sleeve 27 and The second extrusion pads 25 are all buckled inside the first seal...

Embodiment 3

[0034] This embodiment is an improvement made on the basis of Embodiment 2. The locking device 3 includes an air delivery channel 31, the air delivery channel 31 is buckled in the inner wall of the wall sleeve 21, and one end of the air delivery channel 31 extends to the overcoat 1, the other end of the air delivery channel 31 runs through the inner wall of the wall cover 21 and is connected with a first folded tube 32, and the inner wall of the wall cover 21 is provided with a second limit air cushion 34 and a first limit air cushion 33, and the second limit air cushion 33 The position air cushion 34 and the first position-limiting air cushion 33 wrap one end of the first turning tube 32, and when the first turning-over tube 32 is inflated and expanded, the second position-limiting air cushion 34 and the first position-limiting air cushion 33 are used to limit the first position. A folded tube 32 is inflated and expanded to squeeze the second squeeze pad 25 at an angle.

Abstract

The invention relates to the technical field of air column bags, and discloses an air column bag of a co-extrusion film air-tight and air-tight sealing body. The air column bag comprises an outer sleeve and a connector device arranged on the outer sleeve, wherein the connector device comprises a wall sleeve; the wall sleeve is connected with the outer sleeve; a connecting sleeve extending into the outer sleeve is connected in the wall sleeve; a first sealing taper sleeve is arranged on the wall sleeve; the outer surface of the connecting sleeve abuts against the inner wall of the first sealing taper sleeve; the inner wall of the wall sleeve is in sliding connection with an extrusion device; the extrusion device comprises a push ring; the push ring slides on the inner wall of the extrusion device; and the first sealing taper sleeve is extruded to deform through axial movement of the push ring so as to seal the connecting sleeve. A second extrusion pad is arranged to evenly apply pressure to the outer surface of a second sealing taper sleeve to better seal the connecting sleeve, the device can achieve multi-stage sealing through cooperation of a first extrusion pad and the second extrusion pad, and impact resistance is achieved.

Description

technical field [0001] The invention relates to the technical field of air-column bags, in particular to an air-column bag with a co-extruded film air-tight air-lock seal. Background technique [0002] With the rapid development of social economy, air column bags, also known as buffer air column bags, inflatable bags, bubble column bags, and columnar inflatable bags, are new packaging materials filled with natural air in the 21st century. Protection, to minimize the loss rate of product transportation. The air-packing bag has the characteristics of anti-stretch and balance, and the surface has good printability. Through continuous pressing, it forms an airtight inflatable column. [0003] However, the air column bag of the existing co-extruded film air-tight air-lock seal body has a poor automatic air-lock effect and has no impact resistance effect, resulting in internal gas leakage; therefore, it does not meet the existing needs, and we have proposed A needle type positio...
