[0018] The subject matter described herein will now be discussed with reference to example embodiments. It should be understood that the discussion of these embodiments is only to enable those skilled in the art to better understand and implement the subject matter described herein, and the functions and arrangements of the elements discussed may be changed without departing from the scope of protection of the contents of this specification. Each example may omit, replace or add various processes or components as needed. In addition, the features described relative to some examples may also be combined in other examples.

[0019] Please refer to Figures 1 to 3 A gas cylinder rapid inflation device, comprising: a preparation machine body 1, a raw gas supply mechanism 2, a connecting mechanism 3 and a gas transmission mechanism 4. The raw gas supply mechanism 2 comprises a rotating platform 21 and six raw gas cylinders 22, and the six raw gas cylinders 22 are evenly distributed on the rotating platform 21; the connecting mechanism 3 is arranged between the preparation machine body 1 and the rotating platform 21, and the connecting mechanism 3 comprises a docking joint 31, a connecting pipe 32, a docking locking assembly 33, a screwing assembly 34, a driving assembly 35 and a linear lifting assembly 36; the docking joint 31 is fixed to the telescopic end of the linear lifting assembly 36, and the docking joint 31 is driven by the linear lifting assembly 36 to descend and align with the raw gas cylinder 22 at a preset position; the docking locking assembly 33 is arranged on the docking joint 31, and one end of the docking locking assembly 33 is connected to the driving assembly 35. The connecting member 35 cooperates with the transmission connection, the other end of the docking locking component 33 is fixed to one end of the connecting pipe 32, and the driving component 35 drives the docking locking component 33 to move, so that the end of the connecting pipe 32 is tightly docked with the interface of the raw gas cylinder 22 and keeps the locked state, and the other end of the connecting pipe 32 is connected to the gas preparation unit inside the preparation machine body 1; the screwing component 34 is arranged at the upper end of the docking head 31, and one end of the screwing component 34 is connected with the driving component 35 for transmission. After the screwing component 34 is docked with the screw switch 23 on the top of the raw gas cylinder 22, the screwing component 34 is driven to rotate by the driving component 35 to turn the screw switch 23 on or off.

[0020] It should be noted that when the above-mentioned inflation device is in use, the gas delivery mechanism 4 is connected to the gas cylinder to be inflated, and the docking joint 31 is driven downward by the linear lifting component 36. When the docking joint 31 is lowered to the preset position, the docking joint 31 is aligned with the top of the raw gas cylinder 22 below. At this time, the screwing component 34 moves downward to cooperate with the screw switch 23 on the top of the raw gas cylinder 22, and the end of the connecting pipe 32 is also horizontally aligned with the interface on the top of the raw gas cylinder 22. Afterwards, the driving component 35 first drives the docking locking component 33 to move, so that the docking locking component 33 drives the end of the connecting pipe 32 to move horizontally with the original The interface of the raw gas cylinder 22 is docked. After the two are completely docked, the docking locking component 33 contacts and presses against the top of the raw gas cylinder 22 to lock the connecting pipe 32, so that it remains tightly connected with the interface of the raw gas cylinder 22. Then, the driving component 35 continues to drive. At this time, since the driving component 35 is temporarily separated from the docking locking component 33 and is transmission-connected with the screwing component 34, the driving component 35 continues to drive and will no longer drive the docking locking component 33 to move, but will drive the screwing component 34 to rotate, thereby causing the screwing component 34 to drive the screw switch 23 of the raw gas cylinder 22 to rotate. The gas outlet of the raw material gas cylinder 22 is opened, and the raw material gas inside is discharged and introduced into the gas preparation unit inside the preparation machine body 1 through the connecting pipe 32. After being prepared by the preparation unit, it is transported to the gas cylinder to be filled through the gas delivery mechanism 4. When the raw material gas of the first component is introduced, the driving component 35 drives the screwing component 34 to rotate in the opposite direction, so that the interface of the raw material gas cylinder 22 is closed, and the driving component 35 is separated from the screwing component 34, and at the same time cooperates with the docking locking component 33 to drive the end of the connecting pipe 32 to separate from the interface of the raw material gas cylinder 22, and then the linear lifting component 3 is driven to rotate the screwing component 34 in the opposite direction. 6 drives the docking head 31 to move up and reset, and then rotates through the rotating platform 21, driving the raw material gas cylinder 22 of the next component to rotate at a preset angle and then stop. At this time, the raw material gas cylinder 22 of the next component arrives at the preset station and keeps the upper and lower alignment with the docking head 31. Then repeat the above operation to introduce the raw material gas of the next component into the gas cylinder to be inflated. The operation is circulated until all the raw material gas is introduced into the gas cylinder to be inflated and the inflation is completed. In this way, the raw material gas cylinder 22 is automatically replaced, replacing the manual replacement operation, reducing the workload of the staff, and achieving the purpose of speeding up the inflation of the gas cylinder.

[0021] Please refer to Figures 4 to 5The docking locking assembly 33 includes a threaded rod 331, a tightening rod 332 and two connecting sliders 333. The threaded rod 331 is rotatably installed in the docking joint 31. The two ends of the outer side of the threaded rod 331 are provided with threads in opposite directions. One end of the two connecting sliders 333 is respectively fixed to the connecting pipe 32 and the tightening rod 332. The other ends of the two connecting sliders 333 are respectively threadedly connected to the two ends of the outer side of the threaded rod 331. The outer sides of the two connecting sliders 333 are both slidably connected to the docking joint 31, and the tightening rod 332 is slidably installed at one end of the docking joint 31.

[0022] The connecting pipe 32 is locked to the bottom of the connecting pipe 32, and the connecting pipe 32 is locked to the bottom of the connecting pipe 32.

[0023] Please refer to Figure 6 The screw assembly 34 includes a turntable 341, a rotating shaft 342 and five rotating contacts adapted to the screw switch 23. The top end of the rotating shaft 342 is rotatably connected to the upper end of the docking head 31, and the bottom end thereof is fixedly connected to the top of the turntable 341. The five rotating contacts are evenly distributed around the bottom of the turntable 341, and the rotating contacts are used to be plugged into the gap position of the screw switch 23.

[0024] It should be noted that when the above-mentioned screwing assembly 34 is in use, after the docking joint 31 moves down to the preset position, the five rotating contacts are respectively inserted into the gaps of the raw gas cylinder 22 and the screw switch 23, and the driving assembly 35 drives the rotating shaft 342 to rotate, so that the turntable 341 drives the five rotating contacts to rotate together, and then drives the screw switch 23 to rotate, so that it is in an open state. After the raw gas is introduced, the driving assembly 35 drives the turntable 341 to rotate in the opposite direction, and the screw switch 23 can be turned to close.

[0025] Please refer to Figures 6 to 9, due to the inconsistency in the tightening degree of the rotary switch 23 of each raw gas cylinder 22 and the problem of the rotation accuracy of the rotating platform 21, the screw assembly 34 may not be precisely aligned with the screw switch 23, so that the screw assembly 34 cannot be properly plugged with the screw switch 23, and manual adjustment is often required. Therefore, in order to further solve this problem, the present invention optimizes the above scheme. The specific scheme is as follows: the rotating contact member includes a contact rod 343, a ball 344, a support spring 345, a clamping body 346 and two limit sliding shafts 347, the bottom of the turntable 341 is provided with a slide groove 348 with the same number as the rotating contact members, and both sides of the inner wall of the slide groove 348 are provided with a rising groove 34 9. The rising groove 349 is an inclined linear groove structure. The top of the contact rod 343 slides correspondingly with the slide groove 348. The ball 344 is rotatably installed at the bottom of the contact rod 343. The support spring 345 is fixedly installed between the contact rod 343 and the inner wall of the slide groove 348. The two limit sliding shafts 347 are respectively fixedly installed on both sides of the top of the contact rod 343. The ends of the two limit sliding shafts 347 are respectively slidably connected with the two rising grooves 349. A matching slot 3410 is provided on one side of the inner wall of the slide groove 348. One end of the clamping body 346 is fixedly connected with the top of the contact rod 343, and the other end thereof is clamped with the matching slot 3410. The inclination of the matching slot 3410 is the same as that of the rising groove 349.

[0026] It should be noted that when the above-mentioned rotating contact piece is in use, during the process of the screw assembly 34 moving downward and plugging into the screw switch 23 below, if the rotating contact piece is aligned with the gap of the screw switch 23, the contact rod 343 can be smoothly inserted into the gap. When the screw switch 23 is turned to open, the top of the contact rod 343 is resisted by the inner wall of the slide groove 348, so that it will not move and can rotate with the turntable 341, thereby driving the screw switch 23 to turn to open. When the screw switch 23 is turned to close, the clamping action of the clamping body 346 and the matching clamping groove 3410 generates a pulling force on the contact rod 343, so that it will not slide in the slide groove 348. If the rotating contact piece is not aligned with the corresponding gap of the screw switch 23, when the ball 344 contacts the top of the screw switch 23, an upward force will be generated on the contact rod 343. Under the guidance of the rising groove 349, the contact rod 3 43 moves upward and squeezes the support spring 345 to contract. Since the inclination of the locking body 346 and the rising groove 349 is the same, the locking body 346 can move with the contact rod 343 and separate from the matching locking groove 3410. When the contact rod 343 is aligned with the gap between the rotary switch 23, it is no longer squeezed by the rotary switch 23, and under the elastic force of the support spring 345, it automatically extends downward to the gap between the rotary switch 23. In this way, the self-adaptive adjustment function of the contact rod 343 is realized through the tilting movement of the contact rod 343, so that the contact rod 343 can be accurately plugged into the gap between the rotary switch 23 without manual adjustment, thereby ensuring that the rotary assembly 34 and the rotary switch 23 are successfully plugged in once. In addition, the elastic sliding setting of the contact rod 343 can avoid direct rigid contact between the bottom end of the contact rod 343 and the rotary switch 23, thereby preventing damage to the rotary switch 23.

[0027] Please refer to Figure 6 and Fig.10 The driving assembly 35 includes a driving motor 351, an incomplete gear 352, a transmission gear 353 and a transmission member. The driving motor 351 is fixedly mounted on the top of the docking joint 31. The incomplete gear 352 is located inside the docking joint 31, and its top is fixed to the rotating end of the driving motor 351. The transmission gear 353 is fixedly sleeved on the outer side of the rotating shaft 342. One end of the transmission member is meshed with the incomplete gear 352, and the other end is connected to the docking locking assembly 33 in a transmission manner. The transmission member includes a passive gear 354, a transmission rod 355 and two bevel gears 356. The transmission rod 355 is rotatably mounted inside the docking joint 31. The passive gear 354 is fixedly mounted on the top of the transmission rod 355, and its outer side is meshed with the incomplete gear 352. The two bevel gears 356 are respectively fixed to the bottom end of the transmission rod 355 and the outer side of the threaded rod 331, and the outer sides of the two bevel gears 356 are meshed.

[0028] It should be noted that when the driving assembly 35 is in use, the incomplete gear 352 drives the passive gear 354 to rotate by driving the motor 351, and the transmission rod 355 rotates together with the passive gear 354, and finally the two bevel gears 356 rotate together, which can drive the threaded rod 331 to rotate, and finally the connecting pipe 32 is movable to dock with the interface of the raw gas cylinder 22, and when the incomplete gear 352 is separated from the passive gear 354, the end of the connecting pipe 32 is completely docked with the interface of the raw gas cylinder 22, and the incomplete gear 352 is also meshed with the transmission gear 353, and the incomplete gear 352 is meshed with the transmission gear 353. The complete gear 352 rotates, which can drive the transmission gear 353 to rotate, so that the rotating shaft 342 rotates together with the transmission gear 353, and the turntable 341 rotates together with the rotating shaft 342, and the rotary switch 23 can be turned on. In this way, the driving component 35 can successively drive the docking locking component 33 and the screwing component 34 to move, so that the two can complete the docking of the connecting pipe 32 in sequence, and the screwing switch 23 is turned on, realizing a complete automatic connection operation of the connecting pipe 32, without the need for manual auxiliary operation, and sharing a power source 214, thereby reducing the manufacturing cost of the connecting mechanism 3 and reducing the consumption of electric energy.

[0029] Please refer to Figure 3 The linear lifting assembly 36 includes a support frame 361 and an electric push rod 362. The support frame 361 is located between the compounding machine body 1 and the rotating platform 21. The electric push rod 362 is fixedly installed on the top of the support frame 361, and its telescopic end is fixedly connected to the top of the docking head 31.

[0030] It should be noted that when the linear lifting assembly 36 drives the docking head 31 to descend, the electric push rod 362 extends downward, which can drive the docking head 31 to move downward. After the inflation is completed, the electric push rod 362 moves upward, which drives the docking head 31 to move upward and reset.

[0031] Please refer to Figure 1 and Fig.11 The rotating platform 21 includes a base 211, a rotating table 212, a stable frame 213 and a power source 214. The power source 214 is arranged in the base 211, and its driving end is fixedly connected to the bottom of the rotating table 212. The bottom of the preparation machine body 1 is fixed to the top of the base 211, and the stable frame 213 is fixedly installed on the top of the rotating table 212. Six raw material gas cylinders 22 are evenly and movably connected to the stable frame 213. A weighing device 5 is provided on the top of the base 211. The weighing device 5 is used to weigh the weight of the gas cylinder to be inflated in real time.

[0032] It should be noted that after completing the inflation of one component gas, the rotating table 212 is driven to rotate by the power source 214, so that the raw gas cylinder 22 on it rotates along with the rotating table 212. After rotating by a preset angle, the raw gas cylinder 22 of the next component just reaches the position below the screw assembly 34. By rotating the rotating table 212, the raw gas cylinder 22 is switched, so that different raw gas cylinders 22 are connected to the connecting mechanism 3 to transport the raw gas.

[0033] Please refer to Figure 1 The gas delivery mechanism 4 includes a gas delivery pipeline 41 and a connecting fixture 42. The gas delivery pipeline 41 is connected to the gas preparation unit inside the preparation machine body 1. The connecting fixture 42 is connected to one end of the gas delivery pipeline 41. The connecting fixture 42 is used to connect to the gas cylinder to be inflated.

[0034] An example of the present specific implementation mode is described above, but the present embodiment is not limited to the above-mentioned specific implementation mode, which is merely illustrative and not restrictive. A person skilled in the art may make many forms inspired by the present embodiment, all of which are protected by the present embodiment.
