Description

Technical Field

[0001] The utility model relates to the technical field of mechanical engineering, and particularly relates to a filling machine for industrial gases. Background Art

[0002] A gas is a compressible and expandable fluid without a shape but with a volume. Gas is a state of matter. The Chinese utility model patent with the authorization announcement number "CN215215732U" discloses a connecting mechanism for gas filling. A partition is fixedly connected to the top of the bottom plate. A connecting groove is formed in the middle of the partition. A lead screw is rotatably connected inside the connecting groove. The top of the partition is connected with a motor through a U-shaped shell. The output end of the motor is fixedly connected to one end of the lead screw. A threaded sleeve is threadedly connected to the outer surface of the lead screw. One end of the threaded sleeve is fixedly connected to a cross bar. With the cooperation of a storage cover, after the gas filling is completed, the suction valve can be stored inside the storage cover for dust protection, avoiding the dust on the surface of the suction valve from contaminating the gas during the next use.

[0003] The above technical solution adjusts according to the height required by the suction valve, and with the cooperation of a guiding structure, the cross bar drives the suction valve to move up and down. The motor can be installed in both forward and reverse directions to drive the suction valve to a suitable position. Start the air pump to pump the gas inside the collection box into the storage tank through the suction valve. Start the motor again to store the suction valve inside the storage cover, which plays a role in dust prevention for the suction valve. However, the above technical solution still has certain defects. For example, the above device places the collection box on the bottom plate and then controls the suction valve to be adjusted to a suitable position through the motor. However, the collection box may move or tilt due to gas impact or mechanical vibration during the filling process, which may lead to the interruption of the filling process and may also cause gas leakage, thus reducing the practicability of the device.

[0044] Please refer to Figures 1-3 , the present utility model provides a technical solution: a filling machine for industrial gases, including a base 1;

[0045] A limiting device is provided on the base 1;

[0046] The limiting device includes a fixed frame 9, a collection box 10 and two limiting plates 11. First limiting plate grooves 14 are opened on the outer walls of both sides of the fixed frame 9. The two limiting plates 11 are respectively slidably connected inside the corresponding first limiting plate grooves 14. Two fixing rods 12 are fixedly connected to the outer walls of both sides of the fixed frame 9. The front, rear, left and right sides of the two limiting plates 11 are respectively slidably connected to the outer walls of the corresponding fixing rods 12. Return springs 8 are sleeved on the outer walls of the two fixing rods 12. The collection box 10 is slidably connected inside the fixed frame 9. The two ends of the two return springs 8 are respectively fixedly connected to the outer walls of the corresponding limiting plates 11 and the outer walls of the fixing rods 12. Second limiting plate grooves 15 are opened on the outer walls of the left and right sides of the collection box 10. The inner parts of the two limiting plates 11 close to the second limiting plate grooves 15 are respectively slidably connected inside the corresponding second limiting plate grooves 15. The fixed frame 9 is fixedly connected to the upper surface of the base 1.

[0047] Among them, a support plate 3 is fixedly connected to the upper surface of the base 1. A threaded rod groove 16 is formed in the outer wall of the support plate 3. A threaded rod 6 is rotatably connected inside the threaded rod groove 16. A motor 5 is fixedly connected to the upper surface of the support plate 3. The output end of the motor 5 rotatably extends into the threaded rod groove 16 and is fixedly connected to one end of the threaded rod 6. A limiting rod 7 is fixedly connected to the lower surface of the fixing plate on the outer wall of the support plate 3. A gas storage tank 2 is fixedly connected to the upper surface of the end of the base 1 away from the collection box 10. An air pump 4 is fixedly connected to the upper surface of the gas storage tank 2. The input end of the air pump 4 is fixedly connected to the gas storage tank 2 through a hose. A dust-proof cover 13 is fixedly connected to the outer wall of the support plate 3. An air suction valve 17 is arranged inside the dust-proof cover 13.

The air pump 4 is fixedly connected to the air suction valve 17 through a hose. The air suction valve 17 is slidably connected to the outer wall of the limiting rod 7.

[0048] Further, when using this device, it is started by connecting to an external power supply. First, pull the limiting plate 11 to move in the opposite direction, driving the reset spring 8 to contract while placing the collection box 10 into the fixed frame 9. Then release the limiting plate 11. The limiting plate 11 is reset by the force generated by the reset spring 8 and enters the second limiting plate groove 15 at the same time, thereby realizing the fixation of the collection box 10. Then, the output end of the motor 5 rotates to drive the threaded rod 6 to rotate while driving the air suction valve 17 to move downward, so that the height of the air suction valve 17 can be adjusted according to the height of the collection box 10.

[0049] Further, after adjustment, the air pump 4 pumps the air inside the collection box 10 through a hose and transports it into the gas storage tank 2. Then, the motor 5 can reset the air suction valve 17 into the dust-proof cover 13 to protect it from dust.

[0050] By pulling the limiting plate 11 to move in the opposite direction in the limiting device, driving the reset spring 8 to contract while placing the collection box 10 into the fixed frame 9. Then release the limiting plate 11. The limiting plate 11 is reset by the force generated by the reset spring 8 and enters the second limiting plate groove 15 at the same time, thereby realizing the fixation of the collection box 10. This facilitates the fixation of the collection box 10 and avoids the interruption of the packaging process caused by the movement or tilt of the collection box 10 due to impact or mechanical vibration, effectively improving the practicability of the equipment. The output end of the motor 5 rotates to drive the threaded rod 6 to rotate while driving the air suction valve 17 to move downward, so that the height of the air suction valve 17 can be adjusted according to the height of the collection box 10. This facilitates the air suction of collection boxes 10 with different heights, effectively improving the flexibility of the equipment and at the same time improving the work efficiency of the staff.

[0051] Working principle: First, pull the limit plate 11 to move in the opposite direction, driving the reset spring 8 to contract while placing the collection box 10 into the interior of the fixed frame 9. Then, release the limit plate 11. The limit plate 11 is reset by the acting force generated by the reset spring 8 and enters the interior of the second limit plate groove 15, thereby realizing the fixation of the collection box 10. Then, the output end of the motor 5 rotates to drive the threaded rod 6 to rotate while driving the suction valve 17 to move downward, so that the height of the suction valve 17 can be adjusted according to the height of the collection box 10. After adjustment, the air pump 4 extracts the air inside the collection box 10 through the hose and transports it to the interior of the air storage tank 2. Then, the motor 5 can reset the suction valve 17 into the interior of the dust-proof cover 13 to prevent dust from it.
