[0030] like Figure 1 As shown, a telescopic mechanism 3 perpendicular to the top surface of the placement platform 1 is provided above the placement platform 1. The telescopic mechanism 3 is connected to the placement platform 1 through an L-shaped bracket 2. The telescopic mechanism 3 is one of a cylinder, an electric lifting rod or a hydraulic cylinder.

[0031] After the cylinder is placed, a clamping mechanism for clamping and fixing the cylinder is installed on the L-shaped bracket 2, wherein Figure 1As shown, the clamping mechanism includes a strip groove 20 opened on the L-shaped bracket 2, and a second bidirectional screw rod 21 is arranged in the strip groove 20. The end of the second bidirectional screw rod 21 is fixedly connected to the end of the strip groove 20, and a second driving motor 22 is installed at one end of the second bidirectional screw rod 21. Arc-shaped clamping plates 24 coaxially corresponding to the circular groove 28 are arranged on both sides above the placement table 1. The two arc-shaped clamping plates 24 are relatively far away from each other. The strip brackets 23 are arranged at both ends of the second bidirectional screw rod 21 and are threadedly connected to the second bidirectional screw rod 21.

[0035] When the filling joint 8 moves toward the steel cylinder, a connecting rod 16 is installed on the pressing block 15, and a second movable plate 14 is arranged on the connecting rod 16. The top of the second movable plate 14 is threadedly connected with the first bidirectional screw rod 5. The pressing block 15 will also approach the steel cylinder with the rotation of the first bidirectional screw rod 5, and press against the side of the steel cylinder away from the filling joint 8, so that a relative clamping effect is formed between the pressing block 15 and the filling joint 8, so as to improve the docking effect of the filling joint 8 on the steel cylinder valve; wherein, the connecting rod 16 slides through the second movable plate 14, and a second compression plate 14 is sleeved on the connecting rod 16 Spring 36, one end of the second compression spring 36 is fixed on the pressure block 15, and the other end of the second compression spring 36 is fixed on the second movable plate 14, and has the same function as the first compression spring 18, so that the second compression spring 36 generates an elastic force acting on the pressure block 15 after the pressure block 15 contacts the steel cylinder, so as to improve the effect of the pressure block 15, and the filling joint 8 and the pressure block 15 can slide after contacting the steel cylinder, so as to ensure that the effect of the filling joint 8 and the pressure block 15 is not limited by the specifications of the steel cylinder (i.e. the size and length of the steel cylinder valve, etc.), thereby improving the applicability of the filling station.

In the actual operation process, for the steel cylinder placed on the support seat 31, the telescopic mechanism 3 drives the U-shaped frame 4 to descend and approach the valve at the top of the steel cylinder, and then after the filling joint 8 is facing the valve, the U-shaped frame 4 provides movement. At this time, the first bidirectional screw rod 5 controls the two moving plates to approach the valve of the steel cylinder, and the filling joint 8 will be connected to the valve mouth of the valve, and the pressing block 15 will be against the back of the valve to ensure that the filling joint 8 is evenly stressed when it is connected to the valve. Then, the end of the support tube 9 away from the filling joint 8 is connected to the telescopic hose 10, and the telescopic hose An electric control valve is provided on 10, which is connected to the controller through a wire and is used for switch control during the carbon dioxide filling process.

After the filling connector 8 is connected to the cylinder valve, the high-pressure gas injection pump 11 will pump the carbon dioxide in the buffer tank 13 into the cylinder to complete the filling, and the buffer tank 13 is connected to the carbon dioxide storage station through a delivery pipe. The buffer tank 13 plays a gas buffering function to prevent the occurrence of a similar "water hammer effect".

[0037] In order to prevent the filling joint 8 and the pressing block 15 from slipping due to the elastic effect of the compression spring after the filling joint 8 and the pressing block 15 are removed from the cylinder valve, a second limit plate 17 is installed on the ends of the connecting rod 16 and the supporting tube 9 that are away from each other.

[0038] Further, such as Figure 1 As shown, at least one first guide rod 34 is provided in parallel on the side of the telescopic mechanism 3, the bottom of the first guide rod 34 is fixed on the U-shaped frame 4, and the top of the first guide rod 34 slides through the L-shaped bracket 2 to improve the lifting stability of the U-shaped frame 4.

[0039] Further, such as Figure 1 and Figure 4 As shown, a second guide rod 19 is provided parallel to the lower side of the first bidirectional screw rod 5, and the end of the second guide rod 19 is fixedly connected to the end of the U-shaped frame 4, and the two ends of the second guide rod 19 slide through the first movable plate 7 and the second movable plate 14 respectively, so as to enhance the guiding effect on the movement of the two movable plates, so as to enhance the movement stability of the filling joint 8 and the pressing block 15, and further enhance the stress strength of the two movable plates, so as to prevent the filling joint 8 and the pressing block 15 from bending and damaging the two movable plates or the first bidirectional screw rod 5 due to the interaction of forces after contacting the cylinder valve.
