Description

Technical Field

[0001] This invention relates to automated equipment, and more particularly to an automatic packaging device and method for an air inflator. Background Technology

[0002] Inflatable air bags have become an important packaging material in the packaging field. Before use, air bags need to be inflated by an inflation device. The current inflation process of air bags is usually done manually, that is, the inflation device directly inflates the air bag through the inflation port. This inflation method is not only inefficient, but also complicated in operation, making it difficult to use on a large scale. In the existing technology, an inflation nozzle is also used to speed up the inflation process. That is, an inflation nozzle is sealed and installed at the inflation port of the air bag, and the air bag is inflated through the inflation nozzle. However, since the inflation nozzle is inserted into the inflation channel of the air bag, there are still at least one of the following drawbacks: (1) it is manually inserted, which has low production efficiency and cannot be industrialized for mass production to speed up the process; (2) it is easy to fall off. Because it is manually inserted, it is easy to fall off over time and during transportation, resulting in defective products. Summary of the Invention

[0047] The following description is intended to disclose the present invention and enable those skilled in the art to implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art. The basic principles of the invention defined in the following description can be applied to other embodiments, modifications, improvements, equivalents, and other technical solutions that do not depart from the spirit and scope of the invention.

[0048] Those skilled in the art should understand that, in the disclosure of this invention, the terms "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, the above terms should not be construed as limiting this invention.

[0049] It is understood that the term "a" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element can be one, while in another embodiment, the number of the element can be multiple, and the term "a" should not be understood as a limitation on the number.

[0050] Refer to the accompanying drawings in this application specification. Figures 1 to 8As shown, an automatic sealing device and method for inflatable nozzles according to a first preferred embodiment of this application will be described in the following description. The automatic sealing device for inflatable nozzles includes a vibration posture adjuster 10, a conveying mechanism 20, a pushing mechanism 30, and a heat sealing device 40, wherein the vibration posture adjuster 10, the conveying mechanism 20, the pushing mechanism 30, and the heat sealing device 40 are connected in sequence. The inflatable nozzle to be processed is adjusted in posture by the vibration posture adjuster and then passes through the conveying mechanism 20 and the pushing mechanism 30 to reach the heat sealing device 40. The heat sealing device 40 then fixes the inflatable nozzle to the packaging bag to be processed by heat sealing, that is, the inflatable nozzle is installed into the inflation port of the packaging bag.

[0051] The vibration posture adjuster 10 is connected to the conveying mechanism 20, and the vibration posture adjuster 10 is used to adjust the way the inflatable nozzle to be processed enters the conveying mechanism 20, so as to facilitate subsequent processing. It should be noted that, in this preferred embodiment of the present application, the inflatable nozzle includes an air inlet end and an air outlet end, wherein the inflatable nozzle is a hollow cylindrical structure, and the diameter of the air inlet end of the inflatable nozzle is larger than the diameter of the air outlet end.

[0052] The vibration posture adjuster 10 adjusts the position and posture of the inflatable nozzles to be processed as they enter the conveying mechanism 20 by vibration, and conveys the adjusted inflatable nozzles to the conveying mechanism 20 in a sequential arrangement, that is, the outlet end of the inflatable nozzles to be processed, which are conveyed to the conveying mechanism 20 by the vibration posture adjuster 10, faces forward and the inlet end faces backward, and any two adjacent inflatable nozzles to be processed are arranged along a conveying channel. In other words, the inflatable nozzles to be processed, after being adjusted by the vibration posture adjuster 10, enter the conveying mechanism 20 in a sequential arrangement with the outlet end facing forward and the inlet end facing backward.

[0053] The vibration posture adjuster 10 includes a vibrator 11 and a spiral track 12 disposed on the vibrator 11. The inflatable nozzle to be processed is placed in the vibratory plate of the vibrator 11, and the vibratory plate of the vibrator 11 conveys the inflatable nozzle to the spiral track 12 in a vibrating manner. As the inflatable nozzle moves along the spiral track 12, it is continuously adjusted in posture and angle by the vibration of the vibrator 11. Inflatable nozzles that meet the track requirements will move along the direction of the spiral track 12, while inflatable nozzles that do not meet the track requirements will return to the vibratory plate of the vibrator 11.

[0054] The vibrator 11 includes a vibratory plate 111 and a recovery trough 112 disposed on the outer edge of the vibratory plate 111. The recovery trough 112 is used to receive and store the inflatable nozzles to be processed. The vibratory plate 111 conveys the inflatable nozzles to be processed to the spiral track 12 in a vibrating and rotating manner. The inflatable nozzles conveyed by the vibratory plate 111 to the spiral track 12 will move along the spiral track 12 above the recovery trough 112, or fall from the spiral track 12 into the recovery trough 112.

[0055] like Figures 1 to 6 As shown, the spiral track 12 includes an inner track 121, a first position adjustment mechanism 122, a second position adjustment mechanism 123, a third position adjustment mechanism 124, and a fourth position adjustment mechanism 125 connected to and sequentially connected to the inner track 121. The inner track 121 is positioned above the vibrating disk 111 of the vibrator 11. During rotation, the vibrating disk 111 delivers the air nozzle to the inner track 121. The air nozzle rotates from bottom to top along the track direction of the inner track 121.

[0056] The first position adjustment mechanism 122, the second position adjustment mechanism 123, the third position adjustment mechanism 124, and the fourth position adjustment mechanism 125 are disposed on the outside of the inner ring track 121, and the first position adjustment mechanism 122, the second position adjustment mechanism 123, the third position adjustment mechanism 124, and the fourth position adjustment mechanism 125 are spirally arranged downward on the outside of the inner ring track 121. Some of the inflation nozzles pass through the first position adjustment mechanism 122, the second position adjustment mechanism 123, the third position adjustment mechanism 124, and the fourth position adjustment mechanism 125 in sequence under the action of gravity, while other inflation nozzles fall from the spiral track 12 into the recovery tank 112.

[0057] The inner track 121 includes an inner track wall 1211, an outer track wall 1212, and a spiral track 1213 between the inner track wall 1211 and the outer track wall 1212. The spiral track 1213 extends spirally upward from the bottom. The height of the inner track wall 1211 of the inner track 121 is less than the height of the outer track wall 1212, so that the inflation nozzle can fall back to the vibrating plate 111 from the inner track wall 1211 during the movement along the spiral track 1213, preventing it from falling outward.

[0058] It is worth mentioning that, in this preferred embodiment of the present application, the inner ring track 121 extends obliquely from top to bottom to the first position adjustment mechanism 122, wherein the air inlet slides down from the inner tube track 121 to the first position adjustment mechanism 122.

[0059] Preferably, in this preferred embodiment of the present application, the inclination of the inner track 121 and the first position adjustment mechanism 122 is 15°.

[0060] The inflation nozzles reach the first position adjustment mechanism 122 along the inner ring track 121. The inflation nozzles that enter the first position adjustment mechanism 122 are arranged laterally along the track direction of the first position adjustment mechanism 122, that is, the axial direction of the inflation nozzles is parallel to the track direction of the first position adjustment mechanism 122. The inflation nozzles that do not enter the first position adjustment mechanism 122 slide into the recovery trough 112 and then enter the vibrating plate 111 through the recovery trough 112.

[0061] like Figure 3 As shown, the first position adjustment mechanism 122 includes a first sidewall 1221 and a first adjustment track 1222, wherein the first sidewall 1221 is disposed inside the first adjustment track 1222, and the first adjustment track 1222 extends inwardly at an incline. When the inflation nozzle enters the first position adjustment mechanism 122 from the inner track 121, the inflation nozzle moves along the first adjustment track 1222 and the first sidewall 1221 of the first position adjustment mechanism 122. Since the first adjustment track 1222 is inclined inward, some of the inflation nozzles are arranged side by side on the first adjustment track 1222, relying on the first sidewall 1221.

[0062] It should be noted that, in this preferred embodiment of the present application, the first adjustment track 1222 of the first position adjustment mechanism 122 is inclined inward, preferably by 15°. In short, in this preferred embodiment of the present application, when the air nozzles move from the inner track 121 to the first position adjustment mechanism 122, they are inclined inward along the first position adjustment mechanism 122 and arranged in a row.

[0063] like Figure 4As shown, the second position adjustment mechanism 123 protrudes outside the first sidewall 1221 of the first position adjustment mechanism 122, and a second adjustment track 1230 is formed between the second position adjustment mechanism 123 and the first adjustment track 1222 of the first position adjustment mechanism 122. The second adjustment track 1230 allows the laterally moving air nozzle to pass through, while blocking the vertically moving air nozzle. The vertically moving air nozzle is blocked and returns to the recovery trough 112. It can be understood that the air nozzles via the second position adjustment mechanism 123 include air nozzles with the air inlet facing forward and air nozzles with the air inlet facing backward. Let the air nozzle with the air inlet facing forward be the air nozzle that moves in the opposite direction, that is, the orientation of the air inlet is opposite to the direction of movement of the air nozzle; let the air nozzle with the air inlet facing backward be the air nozzle that moves in the forward direction, that is, the orientation of the air inlet is the same as the direction of movement of the air nozzle.

[0064] In short, in this preferred embodiment of the present application, the second position adjustment mechanism 123 pushes down the vertically moving air nozzle and allows the laterally moving air nozzle to move on the second adjustment track 1230.

[0065] When the inflation nozzle moves from the second position adjustment mechanism 123 to the third position adjustment mechanism 124, the inflation nozzle moving in the forward direction is retained in the third adjustment track 1240 of the third position adjustment mechanism 124, and the inflation nozzle moving in the reverse direction is pushed into the recycling tank 112 by the third position adjustment mechanism 124.

[0066] Specifically, the third position adjustment mechanism 124 includes a third track body 1241, a third locking mechanism 1242, and a slot 1243 formed between the third track body 1241 and the third locking mechanism 1242. The width of the slot 1243 is greater than the width of the air outlet end of the inflation nozzle but less than the width of the air inlet end. When the inflation nozzle enters the third position adjustment mechanism 124 from the second position adjustment mechanism 123, the air outlet end of the inflation nozzle slides to the inside of the slot 1243, while the air inlet end of the inflation nozzle is locked to the outside of the slot 1243.

[0067] like Figure 5As shown, the third position adjustment mechanism 124 further includes a third track extension plate 1244, wherein the third track extension plate 1244 is located outside the third track body 1241, and the third track extension plate 1244 is connected to the second position adjustment mechanism 123. The length of the third track extension plate 1244 is less than the length of the third track body 1241. When the inflation nozzle moves from the second position adjustment mechanism 123 to the third track extension plate 1244 of the third position adjustment mechanism 124, the inflation nozzles moving in the forward direction will be arranged sequentially along the direction of the latch 1243 and move towards the direction of the fourth position adjustment mechanism 125, while the inflation nozzles moving in the reverse direction will slide from the third track extension plate 1244 into the recycling tank.

[0068] It is worth mentioning that, in this preferred embodiment of the present application, the third position adjustment mechanism 124 extends obliquely from the outside to the inside and from the top to the bottom, so that the air outlet end of the air nozzle can be inserted into the slot 1243.

[0069] The third position adjustment mechanism 124 further includes a stop bar 1245, wherein the stop bar 1245 is located at the end of the third track body 1241, and the stop bar 1245 is on the outside of the third locking mechanism 1242, forming an anti-slip structure with the third locking mechanism 1242 to prevent the inflation nozzle from slipping off the third position adjustment mechanism 124.

[0070] The third position adjustment mechanism 124 is located at the front end of the fourth position adjustment mechanism 125. The air nozzle that moves forward when it enters the air nozzle of the fourth position adjustment mechanism 125 from the third position adjustment mechanism 124 is further guided and adjusted by the fourth position adjustment mechanism 124 to prevent the air nozzle from becoming blocked.

[0071] like Figure 6 As shown, the fourth position adjustment mechanism 125 further includes a fourth inner sidewall 1251, a fourth outer sidewall 1252, and a fourth track 1253 located between the fourth inner sidewall 1251 and the fourth outer sidewall 1252. The fourth track 1253 is located below the third track 1240, that is, there is a height difference between the fourth track 1253 and the third track 1240, so that the inflation nozzle can detach from the third track 1240 and fall into the fourth track 1253.

[0072] It should be noted that, in this preferred embodiment of the present application, the width of the fourth track 1253 of the fourth position adjustment mechanism 125 does not exceed twice the width of the air nozzle. The fourth position adjustment mechanism 125 can further adjust the order and relationship of adjacent air nozzles to prevent blockage and accumulation.

[0073] The length of the fourth outer sidewall 1252 of the fourth position adjustment mechanism 125 is less than the length of the fourth inner sidewall 1251. That is, a notch is provided on the outer side of the fourth position adjustment mechanism 125, which allows excess air nozzles to fall into the recycling tank, preventing the air nozzles from becoming blocked and accumulating.

[0074] In this preferred embodiment of the present application, the fourth track 1253 of the fourth position adjustment mechanism 125 is inclined from the outside inward and from the top down to prevent the normally moving air nozzle from disengaging from the fourth track. Preferably, the fourth track of the fourth position adjustment mechanism 125 has an inward inclination of 15°.

[0075] The fourth position adjustment mechanism 125 sequentially conveys each of the forward-moving air nozzles to the conveying mechanism 20. It should be noted that, in this preferred embodiment of the application, since the vibration posture adjuster 10 vibrates during operation, the conveying mechanism 20 conveys the air nozzles with adjusted order and posture to avoid the vibration affecting subsequent processing.

[0076] In detail, the conveying mechanism 20 includes an inflation nozzle conveying track 21, a conveying pipe 22, and a blocking mechanism 23 that restricts the movement sequence of the inflation nozzles within the conveying pipe 22. The inflation nozzle conveying track 21 is conductively connected to the fourth position adjustment mechanism 125 and the conveying pipe 22. The inflation nozzles to be processed are sent from the fourth position adjustment mechanism 125 to the conveying pipe 22 via the inflation nozzle conveying track 21.

[0077] It should be noted that, in this preferred embodiment of the present application, the air nozzle conveying track 21 may be, but is not limited to, a transmission hose, which can prevent the vibration of the vibration posture adjuster 10 from being transmitted to the conveying mechanism 20.

[0078] The inflator to be processed enters the pipe channel 220 of the conveying pipe 22, wherein the conveying pipe 22 is provided with at least one blocking hole 230 corresponding to the blocking mechanism 23, wherein the blocking mechanism 23 is retractable into the blocking hole 230 of the conveying pipe 22 to block the movement of the inflator in the pipe channel 220.

[0079] like Figure 7A and Figure 7BAs shown, the conveying pipe 22 further includes a pipe storage section 221 and a pipe conveying section 222, wherein the pipe storage section 221 is connected to the pipe conveying section 222, and the pipe storage section 221 is located at the front end of the pipe conveying section 222. The inflatable nozzle to be processed moves from the pipe storage section 221 to the pipe conveying section 222. After being conveyed from the inflatable nozzle conveying track 21 to the conveying pipe 22, the inflatable nozzle to be processed is stored in the pipe storage section 221.

[0080] Preferably, in this preferred embodiment of the present application, the conveying pipe 22 extends downwardly from the pipe storage section 221 to the pipe delivery section 222, and the inflation nozzle can slide from the pipe storage section 221 of the conveying pipe 22 to the pipe delivery section 222 under its own gravity.

[0081] The blocking hole 230 of the blocking mechanism 23 is formed between the pipe storage section 221 and the pipe delivery section 222 of the conveying pipe 22, that is, the blocking mechanism 23 can block the air nozzle stored in the pipe storage section 221.

[0082] In this preferred embodiment of the present application, the blocking mechanism 23 further includes a first blocking member 231 and a second blocking member 232, wherein the first blocking member 231 and the second blocking member 232 are spaced apart along the axial direction of the conveying pipe 22, and wherein the first blocking member 231 is located behind the second blocking member 232. Correspondingly, the blocking hole 230 of the conveying pipe 22 includes a first blocking hole 2301 and a second blocking hole 2302, wherein the first blocking hole 2301 corresponds to the first blocking member 231, and the second blocking hole 2302 corresponds to the second blocking member 232.

[0083] The conveying pipe 22 is further provided with a back-end storage position 2201, a front-end conveying position 2202 and a middle-end preparation position 2203 that are interconnected. The middle-end preparation position 2203 is located between the back-end storage position 2201 and the front-end conveying position 2202. The first blocking hole 2301 is located between the back-end storage position 2201 and the middle-end preparation position 2203, and the second blocking hole 2302 is located between the middle-end preparation position 2203 and the front-end conveying position 2202.

[0084] The inflation nozzles conveyed to the conveying pipe 22 are stored in the rear storage position 2201 of the conveying pipe 22, and the inflation nozzles stored in the rear storage position 2201 are blocked by the first stop 231. When the first stop 231 leaves the first stop hole 2301, the inflation nozzles located in the rear storage position 2201 can move to the middle preparation position 2203. The inflation nozzles located in the middle preparation position 2203 are blocked by the first stop 231 and the second stop 232 and are held in the middle preparation position 2203. When the second stop 232 leaves the second stop hole 2302, the inflation nozzles located in the middle preparation position 2203 can move to the front conveying position 2202. The inflation nozzles can be conveyed from the front conveying position 2202 to the pushing mechanism 30 for the next processing operation.

[0085] It should be noted that, in this preferred embodiment of the present application, the middle preparation position 2203 of the conveying pipe 22 can accommodate at most one inflation nozzle, which can prevent two or more inflation nozzles from being transported to the pushing mechanism 30 through the conveying pipe 22 at one time.

[0086] Specifically, the first resist 231 enters the first resist hole 2301 and abuts against the inflation nozzle located in the rear storage position 2201. The second resist 232 enters the second resist hole 2302 and abuts against the inflation nozzle located in the middle preparation position 2203. The inflation nozzle located in the front conveying position 2202 can move along the conveying pipe 22 toward the pushing mechanism 30.

[0087] When the first resist 231 leaves the first resist hole 2301, an inflation nozzle falls from the rear storage position 2201 to the middle preparation position 2203, and the inflation nozzle in the middle preparation position 2203 is blocked by the second resist 232; the first component 231 re-enters the first resist hole 2301 to block the inflation nozzle in the rear storage position 2201; the second resist 232 leaves the second resist hole 2302, and the inflation nozzle in the middle preparation position 2203 slides down to the front conveying position 2202 and moves along the conveying pipe 22 towards the pushing mechanism 30; the second resist 232 re-enters the second resist hole 2302 to realize the lowering of an inflation nozzle.

[0088] The automatic sealing device for the inflation nozzle further includes a blowing mechanism 50, which is disposed on one side of the conveying pipe 22. The conveying pipe 22 is further provided with an air inlet 2204 corresponding to the blowing mechanism 50, wherein the air inlet 2204 is located at the middle preparation position 2203 of the conveying pipe 22. When the second resist 22 leaves the second resist hole 2302, the blowing mechanism 50 can blow air into the air inlet 2204 of the conveying pipe 22, thereby moving the inflation nozzle to the pushing mechanism 30. It is worth mentioning that the gas blown by the blowing mechanism 50 into the air inlet 2204 can form a bidirectional airflow. The downward airflow can push the inflation nozzle downward, while the upward airflow can move the inflation nozzle located in the rear storage position 2201, preventing the inflation nozzle from being stuck by the first resist 231.

[0089] The automatic packaging equipment for inflatable nozzles further includes a detection sensor 60 and a system controller 70, wherein the system controller 70 is electrically connected to the detection sensor 60 and the vibration posture adjuster 10. The detection sensor 60 is used to detect whether there is an inflatable nozzle to be processed in the conveying pipe 22. When the detection sensor 60 does not detect the inflatable nozzle, the system controller 70 controls the vibration posture adjuster 10 to work in order to convey the inflatable nozzle into the conveying pipe 22.

[0090] The conveying pipe 22 is provided with a corresponding detection port 2205, wherein the detection sensor 60 corresponds to the detection port 2205 and detects whether an air filling nozzle exists in the rear storage position 2201 of the conveying pipe 22 through the detection port 2205. As an example, in a specific embodiment of this application, the detection sensor 60 may be, but is not limited to, a laser sensor.

[0091] The conveying mechanism 20 conveys the inflator to be processed to the pushing mechanism 30, and then the pushing mechanism 30 moves the inflator to be processed to the heat sealing device 40, whereby the heat sealing device 40 seals the inflation port of the packaging bag with the inflator.

[0092] like Figure 8 As shown, the pushing mechanism 30 includes a pushing pipe 31 and a pushing rod 32, wherein the pushing rod 32 can reciprocate back and forth along the axial direction of the pushing pipe 31. The air nozzle to be processed arrives from the conveying mechanism 20 to the pushing pipe 31 of the pushing mechanism 30, and is moved by the pushing rod 32 along the pushing pipe 31 to the heat sealing device 40.

[0093] The inflator to be processed falls into the push pipe 31, wherein the push rod 32 is inserted into the air inlet end of the inflator and passes through the inflator, and the push rod 32 carries the inflator along the axial direction of the push pipe 31 to the corresponding position of the heat sealing device 40.

[0094] It is understood that in this preferred embodiment of the present application, the diameter of the push rod 32 is adapted to the inner diameter of the inflation nozzle. As an example, in a specific example of the present application, the push rod 32 may be, but is not limited to, a pneumatic push-pull device.

[0095] The heat sealing device 40 includes a heat sealing main unit 41, a telescopic mechanism 42 disposed on the heat sealing main unit 41, and a heat sealing block 43. The heat sealing main unit 41 is disposed at the end of the push rod 32, and has an extension opening 410 corresponding to the push rod 32. The push rod 32 of the push mechanism 30 carries the inflation port and extends from the extension opening 410 of the heat sealing main unit 41. The heat sealing block 43 is disposed on the telescopic mechanism 42, and the telescopic mechanism 42 can move the heat sealing block 43.

[0096] The telescopic mechanism 42 includes a first telescopic unit 421 and a second telescopic unit 422, wherein the first telescopic unit 421 and the second telescopic unit 422 face each other. The heat-sealing block 43 includes a first heat-sealing unit 431 and a second heat-sealing unit 432, wherein the first heat-sealing unit 431 is disposed below the first telescopic unit 421, and the second heat-sealing unit 432 is disposed above the second telescopic unit 422, and a heat-sealing cavity 420 for fixing the inflation port is formed between the first heat-sealing unit 421 and the second heat-sealing unit 422. The inflation nozzle to be processed is pushed out of the protrusion 410 by the push rod 32 and reaches the position of the heat-sealing cavity 420.

[0097] The first telescopic unit 421 and the second telescopic unit 422 of the telescopic machine 42 can push or pull the first heat-sealing unit 431 and the second heat-sealing unit 432 connected thereto to move, and the first heat-sealing unit 431 and the second heat-sealing unit 432 of the heat-sealing device 40 heat-seal and fix the aligned inflation nozzle and the film of the packaging bag together. It is worth mentioning that the first heat-sealing unit 431 and the second heat-sealing unit 432 of the heat-sealing block 43 are provided with arc mechanisms corresponding to the inflation nozzle. Preferably, in a specific example of this application, the heat-sealing block 43 is an electrically heated mechanism.

[0098] The heat sealing host 41 further includes a limiting structure 411, wherein the limiting structure 411 is set at the position of the protrusion 410. When the push rod 32 pushes the inflation nozzle through the protrusion 410, the limiting structure 411 blocks the front end of the inflation nozzle. The push rod 32 can pass through the inflation nozzle under the resistance of the limiting structure 411, thereby preventing the inflation nozzle from extending too quickly and falling off from the end of the push rod.

[0099] The pushing mechanism 30 further includes a limiting barrier 33, wherein the limiting barrier 33 is disposed on the pushing rod 32 and protrudes outward from the pushing rod 32. When the pushing rod 32 passes through the inflation nozzle, the limiting barrier 33 blocks the rear of the inflation nozzle, thereby preventing the pushing rod 32 from inserting too deeply into the inflation nozzle. The limiting barrier 33 serves to fix the position, securing the inflation nozzle to the front end of the pushing rod 32.

[0100] The push rod 32 is further provided with an adsorption port 320, wherein the adsorption port 320 is formed at the end of the push rod 32 and is directly opposite the inner side of the inflation nozzle. When the push rod 32 is inserted into the inflation nozzle, the inflation nozzle is fixed at the end of the push rod by drawing air in through the adsorption port 320 of the push rod 32, thereby preventing the inflation nozzle from falling off from that end position.

[0101] According to another aspect of this application, this application further provides an automatic sealing method for an inflation nozzle, wherein the automatic sealing method includes the following steps:

[0102] (d) Adjust the position and orientation of the air nozzle to be processed, and sequentially transport the air nozzle to the conveying mechanism 20;

[0105] In step (b) of the automatic packaging method of this preferred embodiment of the application, a first resist 231 is inserted into a first resist hole 2301, and a second resist is inserted into a second resist hole 2302, wherein the second resist blocks the inflation nozzle located in the middle preparation position 2203, and the first resist blocks the inflation nozzle located in the rear storage position 2201; the second resist 232 is pulled out of the second resist hole 2302, the inflation nozzle stored in the middle preparation position is moved to the front delivery position, and the second resist is inserted into the second resist hole 2302 again; the first resist is pulled out of the first resist hole 2301, the inflation nozzle stored in the rear storage position is moved to the middle preparation position, and the first resist is inserted into the first resist hole again.
