Description

Technical Field

[0001] This utility model relates to the field of fully automatic helium filling technology for balloons, specifically a fully automatic helium filling device for balloons. Background Technology

[0002] Helium is a colorless, odorless, and tasteless inert gas that is gaseous at room temperature. It has a low critical temperature and is the most difficult gas to liquefy in nature. It is chemically inert, cannot burn, and does not support combustion. Common balloons filled with helium include aluminum foil balloons, pearl balloons, magic balloons, agate balloons, birthday balloons, and wedding balloons. Helium is usually filled into a helium tank, and then, as needed, the helium is used to fill the balloon.

[0003] Common fully automatic helium filling devices for balloons still have some problems. For example, when filling helium, the connector needs to be connected to the connector of the helium tank, but it is inconvenient to raise or lower the connector as needed, resulting in poor flexibility. Furthermore, it is inconvenient to limit the hose, which can easily affect the filling efficiency.

[0004] Therefore, we propose a fully automated balloon helium filling device to improve upon the above-mentioned problems. Utility Model Content

[0010] As a further technical solution of this utility model, the guide rod slides inside the guide groove, and multiple sets of the limiting rollers are provided.

[0011] As a further technical solution of this utility model, a chain conveyor belt is provided inside the frame, and rotating shafts are movably connected to the left and right sides inside the frame. A sprocket is fixedly connected to the outside of the rotating shaft, and a drive motor is installed on the right side of the front end of the frame.

[0012] Compared with the prior art, the beneficial effects of this utility model are: the fully automatic balloon helium filling device not only realizes convenient and rapid filling and convenient centering of the helium tank, but also facilitates the transportation of the helium tank;

[0013] (1) The system is equipped with a cylinder, hose, limit plate, fixed plate, connector, solenoid valve and pressure sensor. When the position sensor at the bottom of the fixed plate senses that the helium tank has moved to the bottom of the fixed plate, the cylinder is activated. The cylinder drives the connector to descend through the fixed plate, so that the connector is tightly fitted onto the inlet pipe clamp of the helium tank. This allows the connector to be connected to the inlet pipe clamp. After the connection is complete, the solenoid valve and air pump are opened, and the helium tank is filled with air through the connecting pipe and hose. The pressure sensor can detect the pressure inside the helium tank. After the helium tank is full, the solenoid valve and air pump are automatically closed. The limit plate can limit the hose to prevent the hose from getting tangled.

[0014] (2) By setting up a guide plate, guide groove, guide rod, limit roller and hydraulic cylinder, start the hydraulic cylinder, the hydraulic cylinder drives the guide plate and limit roller to move closer to the center, so as to guide the helium tank to the center and prevent the helium tank from deviating and affecting the filling. The guide rod slides inside the guide groove, which can not only limit the guide plate, but also support the two sides of the guide plate.

[0015] (3) By setting up a chain conveyor belt, a rotating shaft, a sprocket and a drive motor, the helium tank is placed at the top of the chain conveyor belt. The drive motor drives the chain conveyor belt to rotate through the rotating shaft and the sprocket, so that the helium tank can be transported. Using the chain conveyor belt to transport the helium tank can realize assembly line operation and improve work efficiency. Attached Figure Description

[0023] The bottom end of the connecting pipe 15 passes through the inside of the gas storage tank 2 and extends to the bottom of the inside of the gas storage tank 2. The connector 23 is fixed inside the limiting sleeve 22, and the hose 10 is movably embedded inside the limiting plate 11.

[0024] Specifically, such as Figure 1 , Figure 3 and Figure 4 As shown, when the position sensor at the bottom of the fixed plate 21 detects that the helium tank has moved to the bottom of the fixed plate 21, the cylinder 9 is activated. The cylinder 9 drives the connector 23 to descend through the fixed plate 21, so that the connector 23 is tightly fitted onto the inlet pipe clamp of the helium tank, thereby connecting the connector 23 to the inlet pipe clamp. After the connection is complete, the solenoid valve 24 and the air pump 14 are opened, and the helium tank is filled with gas through the connecting pipe 15 and the hose 10. The pressure sensor 25 can detect the pressure inside the helium tank. After the helium tank is full, the solenoid valve 24 and the air pump 14 automatically close. The limit plate 11 can limit the hose 10 to prevent the hose 10 from getting tangled.

[0025] Mounting plates 16 are fixedly connected to the front and rear ends of the top of the frame 4. A hydraulic cylinder 20 is installed inside the mounting plate 16. A guide plate 7 is installed at the end of the hydraulic cylinder 20 near the middle. A limit roller 19 is movably connected inside the guide plate 7. Guide rods 18 are fixedly connected to the left and right sides of the guide plate 7 near the outer end. A guide groove 17 is opened at the top of the inside of the frame 4. The guide rods 18 slide inside the guide groove 17. Multiple sets of limit rollers 19 are provided.

[0026] Specifically, such as Figure 1 and Figure 2 As shown, when the hydraulic cylinder 20 is activated, it drives the guide plate 7 and the limiting roller 19 to move closer to the center, thereby guiding the helium tank to the center and preventing the helium tank from shifting and affecting the filling. The guide rod 18 slides inside the guide groove 17, which can not only limit the guide plate 7, but also support the two sides of the guide plate 7.

[0027] The frame 4 is equipped with a chain conveyor belt 5. The left and right sides inside the frame 4 are movably connected to the rotating shaft 6. The rotating shaft 6 is fixedly connected to the outside of the sprocket 12. The right side of the front end of the frame 4 is equipped with a drive motor 13, which is fixedly connected to the rotating shaft 6 through a coupling.

[0028] Specifically, such as Figure 1 As shown, a helium cylinder is placed at the top of the chain conveyor belt 5. The drive motor 13 drives the chain conveyor belt 5 to rotate through the rotating shaft 6 and the sprocket 12, thereby transporting the helium cylinder. Using the chain conveyor belt 5 to transport helium cylinders can realize assembly line operation and improve work efficiency.

[0029] Working Principle: In use, the helium cylinder is placed at the top of the chain conveyor belt 5. The hydraulic cylinder 20 is activated, causing the guide plate 7 and the limiting roller 19 to move towards the center, thus guiding and centering the helium cylinder and preventing it from shifting and affecting filling. The guide rod 18 slides inside the guide groove 17, not only limiting the guide plate 7 but also supporting its sides. The drive motor 13 drives the chain conveyor belt 5 to rotate via the rotating shaft 6 and sprocket 12, thus conveying the helium cylinder. When the position sensor at the bottom of the fixed plate 21 detects that the helium cylinder has moved to the bottom of the fixed plate 21, the drive motor 13 stops driving the rotating shaft 6, and then the cylinder 9 is activated. 9. The fixed plate 21 drives the connector 23 to descend, so that the connector 23 is tightly fitted onto the inlet pipe clamp of the helium tank, thus connecting the connector 23 to the inlet pipe clamp. After connection, the solenoid valve 24 and the air pump 14 are opened, and the helium tank is filled with gas through the connecting pipe 15 and the hose 10. The pressure sensor 25 can detect the pressure inside the helium tank. After the helium tank is full, the solenoid valve 24 and the air pump 14 automatically close. The limit plate 11 can limit the hose 10 to prevent the hose 10 from getting tangled. After full, the drive motor 13 is started again to make the chain conveyor belt 5 move the helium tank. Using the chain conveyor belt 5 to transport the helium tank can realize assembly line operation and improve work efficiency.
