Description

Inflation device and inflation method thereof

Technical Field

The present invention relates to an inflator, and more particularly, to an inflator for continuously and automatically inflating an inflatable cushion body and an inflation method thereof.

Background

In modern society, logistics systems are rapidly developing. Many articles are traded in the form of logistics, such as electronic products, chemical products, medical products, ceramics, glass and other daily necessities, and the like, and the articles are inevitably extruded, collided, dropped and the like in the process of storing or transporting, so that the products are damaged or deformed, and serious losses are brought to people. Various cushioning devices are used during the transportation of goods in order to protect the goods. The conventional paper packaging box cannot provide a good buffering effect and cannot achieve a good protection effect, so that in the using process, products to be packaged are often required to be packaged through multi-layer packaging by using foam, flexible plastic and the like and then are put into the packaging box, so that good anti-falling and anti-collision performance is achieved, the transportation cost is obviously increased, the packaging is extremely inconvenient, the time is wasted, the working efficiency is reduced, the labor cost is increased, and the requirements of the modern transportation industry are not met. Among these cushioning devices, inflatable cushioning devices are increasingly used. The inflatable cushioning device, such as an inflatable bag, is a planar multi-layer material before use, and the inflatable cushioning device is needed to be inflated for three-dimensional molding after use to protect articles.

An inflation device is essential in the inflation process. In the existing inflating operation, the film forming the inflating opening is preferably tightly attached to the air tap, so that air needs to be first introduced into one inflating opening of the inflating bag and then is allowed to enter the corresponding air storage chamber through the inflating opening, however, if the size of the air packaging material is large and the inflating operation with a large depth is required, the air storage chamber may not be effectively filled in time due to the air entering through the single inflating opening, that is, the required inflating pressure in the air storage chamber may not be achieved. The joint degree of the charging connector of some existing charging devices and the air inlet of the charging bag is poor. The air source loss is easy to occur because a relatively sealed environment cannot be formed between the air charging nozzle and the air inlet in the working process of the air charging equipment.

Some existing inflation equipment inflates from the both ends of air bag, and the air inlet of air bag has set up in the tip, and air equipment lacks positioning performance to need the manual location air bag of operating personnel to inflate and singly do not continuously inflate, be unfavorable for improving work efficiency. In the inflation process of the conventional airbag, the conventional airbag is also excessively dependent on manual work, for example, when a small-sized inflator is used, an operator needs to hold the inflator with one hand and hold the air bag adjacent to the inflation port with the other hand, and then inflation operation is performed, or two persons are required to cooperatively operate. For example, when the high-pressure air source is replaced, an operator needs to hold the air bag by two hands, then the air tap of the air charging device is placed at the air charging port of the air bag for charging operation, and in the process of charging operation, the operator needs to hold the air charging packaging bag tightly to prevent the air charging bag from moving due to charging. Also, in conventional inflation operations, essentially a single said airbag is inflated, i.e. multiple airbags cannot be inflated continuously, and thus there is a lack of continuous automated inflation schemes.

In addition, some existing inflation devices are prone to defective products during inflation due to inaccurate positioning, that is, partial inflation of the inflation bag or excessive pressure in the bag is caused during inflation. And after the defective products are taken out, operators need to readjust and correct the inflation equipment, which is not beneficial to improving the efficiency. In order to meet the requirement of higher inflation quality, some inflation devices have complex structures, are inconvenient to operate, have single shape and are inconvenient to move, and the main performance of the inflation device is also affected.

Detailed Description

The following description is presented to enable one of ordinary skill in the art to make and use the invention. The preferred embodiments in the following description are by way of example only and other obvious variations will occur to those skilled in the art. The basic principles of the invention defined in the following description may be applied to other embodiments, variations, modifications, equivalents, and other technical solutions without departing from the spirit and scope of the invention.

Fig. 1 to 9 show a preferred embodiment of an inflatable device according to the present invention for continuously and automatically inflating an inflatable cushion body 10 to form a three-dimensional inflatable cushion body. The inflatable device includes a support 30, a handpiece 40, and a platform 50. The handpiece 40 is disposed on the support 30, and the support 30 is disposed on the platform 50. In this preferred embodiment of the present invention, the handpiece 40 is slidably disposed on the support 30 and is free to slide under gravity to always press against the inflatable cushion body 10, and the inflation apparatus includes a positioning structure to ensure that the inflatable cushion body 10 is not relatively displaced during operation. It will be appreciated by those skilled in the art that the inflatable cushion 10 is sized and dimensioned to accommodate the weight of the handpiece 40. The inflation apparatus is capable of automatically and continuously inflating the inflatable cushion 10 of various specifications and sizes, and the present invention is not limited thereto.

In this preferred embodiment of the invention, the inflation apparatus of the invention is capable of performing an inflation operation on one or more of the inflatable cushion bodies 10 arranged in superposition, i.e., on a wad of the inflatable cushion bodies 10. Each of the inflatable cushion bodies 10 includes at least two air cell films 11 and 12 which are connected to each other by a sealing process such as a heat sealing process or an adhesive process, and one or more air storage units 13 formed by the heat sealing process are preferable in the present invention. As shown in fig. 2A and 2B, a gas storage chamber 14 for storing gas is formed in each of the gas storage units 13. In a single inflation operation of the inflatable cushion 10 of the wad by the inflation arrangement, the gas storage unit 13 of one of the inflatable cushion 10 may be inflated.

More specifically, the two air cell films 11 and 12 are partitioned into the plurality of air storage units 13 by the plurality of rows of partition slits 101, that is, each row of the partition slits 101 may be formed by a heat-sealing process that heat-seals the two air cell films 11 and 12 so that one row of the partition slits 101 is formed between the adjacent two air storage units 13. The separation slits 101 may be continuous heat-seal lines so that the plurality of the air storage units 13 are independent of each other. The separation slits 101 may be intermittent heat-seal lines so as to communicate a plurality of the air storage units 13 with each other. The air storage unit 13 may have various shapes such as a bar shape, a circular shape, a polygonal shape, or other irregular shapes, and the air-filled cushion body 10 of the present invention may include a plurality of air-filled columns arranged side by side as shown in fig. 2A, but the present invention is not limited in this respect.

In this preferred embodiment, the inflatable cushion body 10 further includes an air valve, which is a variety of valve structures capable of achieving one-way check, and in this preferred embodiment of the present invention is an inflation valve 20 formed of at least two valve films 21 and 22, the valve films 21 and 22 of the inflation valve 20 being disposed in overlapping relation with the air chamber films 11 and 12, and an air intake passage 23 for inflating the air reservoir 14 being formed between the valve films 21 and 22. When the air in the air storage chamber 14 is inflated through the air intake passage 23 and the air pressure in the air storage chamber 14 reaches a predetermined requirement, the air pressure in the air storage chamber 14 acts on the valve films 21 and 22 to cause the valve films 21 and 22 to adhere to one of the air chamber films, thereby closing the air intake passage 23 to cause the inflation valve 20 to function as a one-way valve. When at least one air inlet channel 23 is formed in each air storage unit 13 and each air storage unit 13 is independent of each other, when one air storage unit 13 is damaged and leaks air, the other air storage units 13 are not affected, and an air buffering effect can be achieved.

The inflatable cushion body 10 further comprises an inflatable unit 15 connected to each of the air storage units 13, preferably integrally extending from each of the air storage units 13. More specifically, in this preferred embodiment, the air chamber films 11 and 12 form air chamber film main body portions 111 and 121, respectively, and inflation end portions 151 and 152 integrally extending to the air chamber film main body portions 111 and 121, respectively, the air chamber film main body portions 111 and 121 being used to form the air storage unit 13 by a heat sealing process, and that portions of the air chamber films 11 and 12 adjacent to the inflation side form the inflation end portions 151 and 152 of the inflation unit 15, respectively. The inflated ends 151 and 152 are overlapped with each other and connected to each other at their distal edges 1511 and 1521 by an edge heat seal 102, i.e., the edge heat seal 102 is formed by a heat seal process which sealingly heat seals the edges 1511 and 1521 of the inflated ends 151 and 152.

As shown in fig. 2B, at the positions where the air chamber film main body parts 111 and 121 of the air chamber films 11 and 12 are connected to the air charging end parts 151 and 152, respectively, the air chamber films 11 and 12 are connected to the valve films 21 and 22, respectively, by an air charging passage heat sealing slit 103, as the air charging passage heat sealing slit 103 is formed by subjecting four films to a heat sealing process, which heat-seals the air chamber film 11 and the valve film 21 in a sealed manner, and heat-seals the air chamber film 12 and the valve film 22 in a sealed manner, but does not heat-seal the valve films 21 and 22 in a sealed manner, thereby forming an air charging passage 23 between the valve films 21 and 22, which can charge the air storage unit 13.

It should be noted that, when the heat sealing process forms the inflation channel heat seal 103, a heat-resistant barrier may be placed between the valve films 21 and 22 so that the valve films 21 and 22 are not heat-sealed together. In this preferred embodiment, a plurality of heat-resistant layers 24, such as high temperature-resistant ink or the like, may be provided between the valve films 21 and 22, which are arranged at a distance from each other corresponding to the air intake passage 23, and attached to the inner surface of one of the valve films 21 and 22, so that the heat-resistant layers 24 may be such that the valve films 21 and 22 are not joined together by the heat-sealing operation of the air intake passage heat-sealing slit 103 in the heat-sealing process, so that the air intake passage 23 which may be formed therebetween may be communicated with the air intake passage 153 in the air-charging unit 15.

More specifically, the inflation unit 15 of the inflatable cushion 10 forms the inflation channel 153 between the edge heat seal slit 102 and the inflation channel heat seal slit 103. As shown in fig. 2A, in this example, for convenience of description, the gas storage units 13 are arranged in the longitudinal direction, and the gas charging passages 153 are arranged in the lateral direction, that is, before non-charging, each of the longitudinally arranged gas storage units 13 may communicate with the same gas charging passage 153 arranged in the lateral direction through the corresponding gas inlet passage 23. It can also be said that the inflation channel 153 extends in the width direction of the inflatable cushion body 10 and communicates with each of the air storage units 13 arranged in the length direction thereof.

It is specifically proposed that in the prior art, the inflation channel 153 leaves at least one end opening, which is formed between two films, after heat sealing of the edge heat seal 102 and the inflation channel heat seal 103, however, inflation takes place through the end opening between such films. But this is detrimental to the automated continuous inflation scheme of the illustrated inflatable cushion of the present invention. Thus, in this preferred embodiment of the present invention, the two ends of the inflation channel 153 of the inflatable cushion are each closed by an inflation channel end seal 1030. That is, the inflation end portions 151 and 152 are overlapped with each other and the inflation channel 153, which is closed by the inflation channel end seal 1030 to form an outer closed but inner communicating with each of the intake channels 23, is formed by the two side openings left after heat-sealing by the edge heat seal 102 and the inflation channel heat seal 103. The inflation channel end seal 1030 may be formed by a sealing process such as a heat sealing or bonding process, which seals both ends of the inflation channel 153.

It should be noted that the separation slits 101 at the two ends of the inflatable cushion body 10 form the boundary slits at the outermost sides of the inflatable cushion body, and the inflation channel end seal 1030 may be integrally formed with the outermost separation slits 101, that is, formed in the same heat sealing process, or the inflation channel end seal 1030 may be formed separately, and formed at the two ends of the inflatable unit 15 through an additional heat sealing process.

In order to achieve the inflation operation of the inflatable cushion body by using the inflation device, an air source is conveniently introduced into the inflation channel, and the inflation end 151 has an air inlet 150, so that the inflatable cushion body 10 can be inflated through the air inlet 150. That is, in the process of producing the inflatable cushion body 10, the inflated end portion 151 is perforated by a perforating device to form the air inlet 150, and then the inflated end portion 151 is laminated and sealed with other films.

In the present invention, a certain layer of the film forming the inflator unit 15 is perforated, for example, in this embodiment, the inflator unit 15 has an air inlet 150 implemented as a single film air port. In this way, gas is adapted to enter the inflation channel 153 from the gas inlet 150 in a direction perpendicular to the plane of the inflation channel 153 and then enter each of the gas reservoirs 14 through each of the gas inlet channels 23 of the inflation valve 20 to complete the inflation operation.

That is, in the present invention, the air charging unit 15 is not charged through the end portion like in the prior art, but is charged at the upper surface. The air inlet holes of the prior art are disposed between two films, while the air inlet 150 of the present invention is disposed in one of the air chamber films.

It will be appreciated that in this example, the inflation unit 15 is formed from the air chamber films 11 and 12, and in other possible embodiments it may also be formed from the valve films 21 and 22 of the inflation valve 20, or from one air chamber film and one valve film, as the invention is not limited in this respect.

In addition, the air chamber films 11 and 12 of the air cushion body 10 and the valve films 21 and 22 of the air valve 20, respectively, may be made of various suitable film materials, such as polyethylene film, polypropylene film, polyvinyl chloride film, polyester film, polystyrene film, or composite film, etc., and the present invention is not limited in this respect as long as it is a suitable flexible film. It should be noted that, in order to increase the unidirectional sealing effect, the valve films 21 and 22 of the inflation valve 20 may also be self-adhesive films modified by adding chemical components to the films.

In the present invention, the inflatable cushion 10 forms a plurality of the air reservoirs 14 capable of storing air by a plurality of films, at least two of which are used to form the one-way inflation valve 20. When the air inlet 150 is in the air, the air enters the air charging channel 153, and then is charged into each air storage chamber 14 through the one-way air charging valve 20 formed by two layers of films, and after the air charging is completed, the films forming the air charging valve 20 are automatically attached together due to the action of the pressure in the air storage chambers, so as to prevent the reverse osmosis of the air.

It should be noted that, the inflatable cushion body 10 of the present invention may form a cushion pad after being inflated, which may be placed in another inflatable box to serve as a cushioning material, or may form a plurality of inflatable sidewalls after being inflated, and have an inner accommodating space, so as to form an inflatable packaging bag, in which an article to be packaged may be stored, so that the inflatable packaging bag provides cushioning protection for the article through the plurality of inflatable sidewalls.

Specifically, in this preferred embodiment of the present invention, the platform 50 is implemented to include an inflatable cushion loading platform 50. The platform 50 is capable of holding one or more of the inflatable cushion bodies 10 stacked in a stack. The support 30 includes a vertical strut 31 and a transverse base frame 32, which are connected to the vertical strut 31 to serve as an operation platform. The platform 50 is disposed on the transverse base frame 32. The nose 40 is disposed on the vertical strut 31. The bracket 30 further includes a sliding rail 34, which is disposed on the vertical strut 31. The handpiece 40 includes a slider 41, and the slider 41 has a sliding groove that can slide on the vertical strut 31 along the sliding rail 34, so that the handpiece 40 can have an up-and-down slidable displacement function.

It will be appreciated that the slide rail 34 may also be provided on the handpiece 40, and correspondingly, the bracket 30 has a slide with a slide slot that mates with the slide rail 34. The platform 50 may be provided separately or may be a work table, i.e. the stand 30 with the handpiece 40 assembled is mounted on an environmental surface, so that the environmental surface provides a loading platform for the inflatable cushion body 10.

Further, the handpiece 40 further has an air source inlet and an air charging port 430 as an air source outlet for charging the inflatable cushion body 10. The air source inlet is connected to an air inlet pipe 60 of an external air source device for providing air source, and the air source enters the machine head 40 from the air inlet pipe 60 through the air source inlet and inflates the inflatable buffer body 10 from the inflation inlet 430.

In order to avoid the influence of the relative displacement of the inflatable cushion body 10 during the inflation operation of the inflation apparatus on the continuity of the operation and the yield of the finished product, the head 40 further comprises a positioning device, and the platform 50 is further provided with a limiting structure, such as one or more limiting devices 55. The inflatable cushion bodies 10 which are formed into a stack with the same specification are placed on the platform 50, and the inflatable cushion bodies 10 are in a relatively overlapped state through the limiting device 55 arranged on the platform 50. That is, the outermost separation slits 101 of the outer side of the air cushion body 10 have notches 107 on the outer side thereof, which match the side shape of the stopper 55. The number of the limiting devices 55 may be one or more, and correspondingly, the number of the notches 107 may be one or more. It will be appreciated that a locating hole is also possible, and the stop device 55 is fitted over the locating hole. In this preferred embodiment of the present invention, as shown in fig. 6, each of the limiting devices 55 includes a limiting connection portion 552 and a limiting cap 551 extending from the limiting connection portion 552. The limit connection 552 is connected to the bracket 30, and in other embodiments, the limit connection 552 may be disposed on a side of the platform 50. The length of the limit connection 552 can be adjusted according to the thickness of the wad of air cushion bodies. The limit cap 551 extends from the limit connection 552 and protrudes outward, and has a size larger than the notch 107, so that when the inflatable cushion body 10 is further limited from above the platform 50 by the limit cap 551 during inflation, the air source loss caused by the offset of the air inlet 150 and the air inlet 43 due to the offset of the inflatable cushion body during inflation is avoided.

Of course, those skilled in the art will appreciate that in other embodiments, the stop 55 may be implemented as a stop bar, a stop plate, or the like. The invention is not so limited. It should be noted that the platform 50 may also have a number of notches 107 matching with the limiting device 55, so that the position of the inflated cushion body on the platform 50 may be better adjusted, thereby being more beneficial to realizing the limiting function of the limiting device 55. In this embodiment of the present invention, the recess 107 cooperates with the stop means 55 to act as a stop and also to facilitate horizontal withdrawal of the inflated cushion body 10.

The bracket 30 further comprises a locking device 35 connected to the vertical strut 31, i.e. limiting the nose 40 to the vertical strut 31. In this preferred embodiment of the present invention, the locking device 35 includes a fixing portion 351 and a locking portion 352, the fixing portion 351 is fixedly disposed on the vertical strut 31, the fixing portion 351 and the locking portion 352 are connected by a bolt 353, and the locking portion 352 is capable of performing a pivoting movement about the bolt 353 as a central axis. That is, when the locking part 352 is pivoted to the lower side of the head 40, the bottom of the head 40 can be blocked by the top of the locking part 352, stopping the downward relative displacement, thereby providing an operating space for installing the air cushion 10 in a stack for the non-operating state of the air charging apparatus.

Further, the positioning means of the handpiece 40 are implemented in this preferred embodiment of the invention as a positioning cutter 44. That is, the handpiece 40 further includes a body 42 connected to the slider 41, the positioning cutter 44 disposed at the bottom of the body 42, and an air nozzle 43 connected to the bottom of the body 42, the air nozzle 43 having the air inlet 430, it being understood that the air nozzle 43 may be integrally formed with the handpiece 40 or may be a separate air nozzle device mounted on the handpiece 40. In this embodiment, in order to more fit the air inlet 150 of the inflatable cushion body 10, the air inlet 43 is a cylindrical air inlet made of a silicone material, so that the air inlet 430 can be well matched with the air inlet 150, and air source loss during the inflation process is reduced. Of course, the air charging nozzle 43 may be made of other materials, such as metal or organic materials, and the invention is not limited in this respect.

It should be noted that the positioning cutter 44 comprises one or more blades, and in this preferred embodiment of the invention is implemented as a double blade structure for easier positioning of the wad of inflated cushioning bodies. Specifically, as shown in fig. 9, the positioning cutter 44 has a two-blade structure, and each blade includes a supporting portion 441 and a positioning tip 442, which integrally extends to the supporting portion 441, the supporting portion 441 is located in the main body 42, and the positioning tip 442 protrudes outside the main body 42. It will be understood, of course, that the entire blade may be disposed entirely outside of the body 42 and the invention is not limited in this respect. Due to the gravity of the handpiece 40 itself, the positioning tip 442 can smoothly pierce the plurality of inflatable cushion bodies 10 on the top end of the wad of inflatable cushion bodies without affecting the tightness of the inflation channel 153 of the inflatable cushion bodies 10.

It will be appreciated that the outer sides of the inflation channel end seal 1030 and the outermost separation slits 101 of each of the inflatable cushion bodies 10 define a margin area 17, and that the positioning cutter 44 pierces the margin area 17, such as the margin areas 17 of at least two of the inflatable cushion bodies 10, so as not to affect the sealability of each of the gas storage units 13 and the inflatable units 15.

When the inflation process is performed, the locking device 35 is in an unlocked state, the sliding block 41 of the machine head 40 is matched with the sliding rail 34 connected to the vertical supporting rod 31, and the machine head 40 can freely fall along the sliding rail 34 to contact with the inflation buffer 10 in a wading manner through the self gravity of the machine head 40. At this time, the positioning cutter 44 on the handpiece 40 is vertically inserted into the wad of the inflatable cushion body 10 until it is free to rest in an equilibrium state.

Further, the external air source device may be an air pump, which is turned on, and enters the air inlet nozzle 43 of the handpiece 40 via the air inlet pipe 60, and then enters the air charging channel 153 from the air charging port 430 of the air inlet nozzle 43, and the air charging channel 153 expands to open the air charging valve 20, so as to charge each air storage chamber 14. After the air source device is opened, air forms downward high-pressure air flow through the air source inlet of the air inlet pipe 60 and the air charging port 430 of the air charging nozzle 43 by the internal mechanism of the machine head 40, and the air flow enters the air charging channel 153 through the single-membrane air inlet 150 of the uppermost inflatable cushion body 10 of the inflatable cushion body in a wading mode, so that the inflatable cushion body 10 is inflated. At the same time, the inflation channel 153 expands to cause the air inlet 150 of the upper single film forming the inflation channel 153 to contact with the inflation inlet 430 of the handpiece 40, and after the air pressure reaches a certain range, the pressure is enough to enable the upper single film to be tightly attached to the inflation inlet 43 of the handpiece 40, that is, the inflation inlet 430 can be tightly attached to and communicated with the air inlet 150, and the inflation inlet 43 and the upper single film forming the inflation channel 95 form a relatively airtight environment so as to maintain the inflation air pressure.

After the inflation of the topmost inflatable cushion body 10 of the stack is completed, the inflated inflatable cushion body 10 can be pulled out horizontally. Since the positioning cutter 44 is vertically inserted into the wad of air cushion bodies all the time, the pulled out air cushion body 10 is cut off in accordance with the pulling track at the positioning position of the positioning cutter 44. Because of the gravity of the handpiece 40 and the positioning of the positioning cutter 44, the uppermost inflatable cushion 10 is pulled out, and the cushion not inflated below is not displaced, so that the overlapping state of the wad of inflatable cushions can be continuously maintained.

After the first inflatable buffer body is pulled out, under the constraint of the sliding rail 34 and the influence of the gravity of the machine head 40, the machine head 40 automatically moves downwards, and meanwhile, the second inflatable buffer body is exposed on the uppermost surface of the inflated buffer body, and similarly, the inflated buffer body 10 is inflated through the inflation port of the upper single film forming the inflation channel 95, and is pulled out after inflation is completed, and the like, so that a working cycle is formed until the inflation of the inflated buffer body of the whole stack is completed, and the air source device is closed. It should be noted that, since the number of the inflatable cushion bodies 10 is too large, that is, the thickness of the entire wad is relatively large in value, the positioning accuracy of the inflatable device is affected. Thus, preferably, the number of inflatable cushion bodies 10 placed on the platform 50 at a time is optimally adjusted in value according to the weight of the handpiece 40.

When the head 40 is lifted and the locking device 35 is in the locked state, the head 40 cannot be dropped. At this point, a new inflated wad of the inflated cushion body 10 may be placed on the platform 50 and the previous inflation step continued. During inflation, the stop devices 55 are used to make the inflatable cushion bodies of the wad coincide relatively, the locking devices 35 are placed in an unlocked state, and the machine head 40 slowly drops under the influence of gravity so that the positioning cutter 44 is inserted into the inflatable cushion body 10 of the wad. Starting the air source again, continuously inflating the newly added wading inflatable buffer body, starting the inflation of the first inflatable buffer body 10, and forming an automatic seal with the inflatable buffer body 10 after the inflation is finished. And taking off the inflatable cushion body 10, and starting to inflate the inflatable cushion body 10, and repeating the cycle until all the inflatable cushion bodies 10 are inflated. Only the air supply needs to be maintained in the whole process. Thus, the inflation apparatus forms a work cycle that enables continuous automatic inflation of the wad of inflatable cushion bodies 10, providing a continuously automated inflation scheme. And when a certain inflatable buffer body needs to be supplemented with air, the inflatable buffer body can be further inflated through the air inlet 150 by a handheld inflation pump.

It will be appreciated by those skilled in the art that the inflation apparatus is simple in structure, can accommodate inflation of different inflatable cushions by adjusting the relative positions of the head and the loading platform and the various specifications of the loading platform, and can be formed in a table-type, portable or other custom-made model without affecting the main performance of the inflation apparatus, and the invention is not so limited.

(c) An air source enters an air inlet 150 of the inflatable cushion body 10 through an air inlet 430 of an air charging nozzle 43 of the air head 40, then enters an air charging channel 153 through the air inlet 150 and finally enters each air storage chamber 14 of the inflatable cushion body 10, wherein the air charging port 430 of the air head 40 corresponds to the air inlet 150 in position and the air charging nozzle 43 contacts the surrounding area of the air inlet 150 of the air charging unit 15 to form a relatively closed environment;

(d) The first inflatable cushion body 10 on the top layer of the inflated cushion bodies is taken out after being inflated, and meanwhile, the positioning cutter 44 cuts off the non-inflated margin area 17 of the first inflatable cushion body 10 according to the pulling track, and the inflation port 430 of the machine head 40 is separated from the air inlet 150 of the first inflatable cushion body 10;

(e) The machine head 40 automatically moves downwards due to self gravity, and the second inflatable buffer body 10 contacted with the bottom of the machine head 40 is continuously inflated;

(f) And (3) repeatedly executing the steps (c) to (f) by the air charging equipment until the air source supply is closed after the whole air charging buffer body is completely charged.
