On the top surface of the box body 2, a sub-packaging tank 5 is installed. At the front end of the box body 2, two symmetrically arranged movable doors 4 are hinged, so that the box body 2 is in a closed space, which can reduce the entry of dust in the air into the box body 2. On one side of the sub-packaging tank 5, an intake pipe 6 is fixedly connected through. A threaded cap is threadedly connected to the intake pipe 6 to prevent dust from adhering to the pipe orifice of the intake pipe 6. Below the sub-packaging tank 5, it is fixedly connected through an outlet pipe 20 to a flow-dividing shell 17 fixed to the inner wall of the upper end of the box body 2. Below the flow-dividing shell 17, multiple pairs of flow-dividing pipes 18 fixed to a fixing plate 10 are connected. Multiple pairs of flow-dividing pipes 18 can simultaneously fill multiple sub-packaging steel cylinders. The side wall of the fixing plate 10 is horizontally fixed to the inner wall of the box body 2. The outlet pipe 20 is located inside the box body 2. The fixing plate 10 is located below the flow-dividing shell 17. The fixing plate 10 fixes the lower ends of the flow-dividing pipes 18. The fixing plate 10 is provided with holes 11 corresponding to the flow-dividing pipes 18, so that the gas in the flow-dividing pipes 18 can pass through the fixing plate 10. The outer wall of the lower end of the flow-dividing pipe 18 is fixed to the inner wall of the hole 11. Below each pair of flow-dividing pipes 18, a baffle 23 sliding on the bottom surface of the fixing plate 10 is horizontally provided correspondingly. At both ends of the baffle 23, a connecting rod 19 is horizontally fixed through an L-shaped plate 22. The L-shaped plate 22 is slidably connected to the fixing plate 10, and the lower wall of the upper end of the L-shaped plate 22 is slidably connected to the top surface of the fixing plate 10. The L-shaped plate 22 can make the baffle 23 slide stably on the fixing plate 10. On one side of each baffle 23, a cleaning rod 24 slidably connected to the fixing plate 10 is horizontally fixed. The cross-section of the cleaning rod 24 is in the shape of a right-angled trapezoid. When the baffle 23 moves, the baffle 23 drives the cleaning rod 24 to clean the dust on the adjacent fixing plate 10, so that the dust will not adhere to the top surface of the baffle 23, and thus there is no dust between the baffle 23 and the port of the flow-dividing pipe 18. Between adjacent two baffles 23, a stop rod 21 fixed to the fixing plate 10 is horizontally provided. One end of the connecting rod 19 is connected to a horizontal reciprocating movement assembly. The horizontal reciprocating movement assembly includes a fixing frame 12 fixed to the outer wall of the box body 2. The cross-section of the fixing frame 12 is in the shape of a U. Inside the fixing frame 12, a connecting shaft 13 is horizontally rotatably connected. One end of the connecting shaft 13 is fixed with a motor 16. The motor 16 is fixed to the outside of the fixing frame 12. At both ends of the connecting shaft 13, gears 14 are fixed. The gears 14 are all meshed with a rack 15 horizontally sliding in the box body 2. One end of the rack 15 is fixed to one end of the connecting rod 19. On the outer wall of the box body 2, a protective shell 3 sleeved outside the horizontal reciprocating movement assembly is fixed. The protective shell 3 can prevent the dust in the air from entering the box body 2 from the connection between the box body 2 and the rack 15. The protective shell 3 can also protect the structure outside the box body 2. On the top surface of the base 1, a cylinder 7 is fixed. The movable end of the cylinder 7 is horizontally fixed with a support plate 8. On the top surface of the support plate 8, a movable plate 25 located below the fixing plate 10 horizontally slides. There are four cylinders 7. The four corners of the bottom surface of the support plate 8 are respectively fixed to the movable ends of the four cylinders 7. The support plate 8 is located inside the box body 2.A bearing seat 9 corresponding to the shunt pipe 18 is fixedly installed on the top surface of the movable plate 25. The movable plate 25 can slide outwards on the support plate 8, facilitating the installation of the sub-packaging cylinder in the bearing seat 9 or the removal of the sub-packaging cylinder from the bearing seat 9.

[0027] The working principle of the present utility model:

[0028] Refer to the attached Figures 1-7 Open the movable door 4, pull out the movable plate 25, install the sub-packaging cylinder in the bearing seat 9, push the movable plate 25 in and then close the movable door 4; start the cylinder 7, the movable end of the cylinder 7 drives the support plate 8 to move upwards, so that the sub-packaging cylinder on the movable plate 25 moves upwards and approaches the baffle 23. When the mouth of the sub-packaging cylinder is about to fit with the baffle 23, the motor 16 is started. The output end of the motor 16 drives the connecting shaft 13 to rotate on the fixed frame 12. The connecting shaft 13 drives the gear 14 to rotate. The gear 14 drives the rack 15 to slide horizontally on the box body 2. The rack 15 drives the connecting rod 19 to move horizontally. The connecting rod 19 drives a plurality of L-shaped plates 22 to slide on the fixed plate 10 at the same time. The L-shaped plates 22 drive the baffle 23 to slide on the fixed plate 10. When the baffle 23 disengages from the shielding of the shunt pipe 18 and reaches the appropriate position, the motor 16 is turned off. At this time, the sub-packaging cylinder continues to move upwards and is connected to the port of the shunt pipe 18. The setting of the baffle 23 can prevent the shunt pipe 18 from contacting the dust in the air and improve the sub-packaging effect; then open the corresponding valve, the gas enters the shunt housing 17 from the air outlet pipe 20 of the sub-packaging tank 5, and then the gas flows out through a plurality of pairs of shunt pipes 18 on the shunt housing 17 and enters the sub-packaging cylinder. The setting of the plurality of pairs of shunt pipes 18 thus realizes the multi-channel inflation structure for sub-packaging a plurality of sub-packaging cylinders; before placing the sub-packaging cylinder until it is connected to the shunt pipe 18, the pipe orifice of the shunt pipe 18 is always in a closed protection state; it solves the problem that when placing the sub-packaging cylinder, the pipe orifice of the sub-packaging pipe is exposed to the air during this period, and the dust in the air will adhere to the pipe orifice, and the dust will enter the sub-packaging cylinder through the sub-packaging pipe, improving the purity of the sub-packaged gas.
