[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the embodiments of the present invention. Example

[0022] See also Figure 1-3 The utility model provides a technical solution: a locking canning mouth sealing device, comprising a support frame 1, a liquid injection pipe 2 and a sealing frame 3 are provided at the bottom of the support frame 1, the liquid injection pipe 2 passes through the sealing frame 3 and can be extended to the tank truck for feeding, the sealing frame 3 can be embedded in the feeding port of the tank truck during feeding and sealed with the feeding port, a stabilizing component for ensuring the sealing effect during filling is provided inside the sealing frame 3, the stabilizing component includes an air bag 4 and a plurality of holes 301 provided on the outer wall of the sealing frame 3, after the sealing frame 3 is embedded in the feeding port, the gap can be filled by the expansion of the air bag 4, thereby achieving sealing, and after the expansion of the air bag 4, the gap between the connecting plate 401 and the inner wall of the feeding port can also be filled;

[0023] A cylinder 302 is provided inside each of the plurality of hole slots 301, and a connecting plate 401 is provided at the output end of the cylinder 302. A latching tooth 402 is provided on the outer wall of the connecting plate 401. The cylinder 302 can drive the connecting plate 401 to abut against the inner wall of the feeding port and support the connecting plate 401. The connecting plate 401 and the external latching tooth 402 can be inserted into the inner wall of the feeding port to make the sealing frame 3 hard-connected to the inner wall of the feeding port and locked, so that the sealing frame 3 needs greater pressure to move or separate from the feeding port, thereby reducing the separation rate;

[0024] The sealing frame 3 is provided with a cavity 5 inside, which is used to limit the angular positioning of the injection tube 2 when it moves in the sealing frame 3. The inner wall of the cavity 5 is provided with multiple air chambers 501. The high-pressure gas in the air chamber 501 can push the connecting rod 601 outward, thereby supporting the position between the sealing frame 3 and the injection tube 2. When the pressure generated when the tank truck is adding materials pushes the sealing frame 3 to detach from the outside of the feeding port, the gas in the air chamber 501 cooperates with the connecting rod 601 to perform pneumatic support (the pressure will cause the sealing frame 3 to slide on the injection tube 2, causing the connecting rod 601 to contract into the air chamber 501, squeezing the gas and increasing the pressure in the air chamber 501. When the pressure sensor detects that the pressure is greater than the set value, it sends a signal and cooperates with the hydraulic cylinder in the support frame 1 to push the sealing frame 3 into the feeding port to correct the position). An air pressure sensor is provided inside the multiple air chambers 501, and a ring 6 is provided on the outer wall of the injection tube 2. Multiple connecting rods 601 are provided at the bottom of the ring 6.

[0025] In this embodiment, all electrical components are controlled by conventional controllers.

[0026] For example, please refer to Figure 1-3 , the injection tube 2 is connected to the bottom of the support frame 1 through a sleeve, and the other end of the injection tube 2 extends to the outside through the cavity 5 through the sealing frame 3, and a hydraulic cylinder is installed on the inner wall of the support frame 1, and the output end of the hydraulic cylinder is connected to the sealing frame 3 through a bolt, and a plurality of the hole grooves 301 are annularly distributed on the outer wall of the sealing frame 3, the cylinder 302 is embedded in the hole groove 301, and the output end extends from the hole groove 301 and is connected to the connecting plate 401 through a bolt, the airbag 4 is sleeved to wrap the outside of the sealing frame 3 and is connected to the outer wall of the sealing frame 3, a plurality of the connecting plates 401 are inlaid and connected to the inner wall of the airbag 4, and are annularly distributed on the airbag 4 outer wall, the distribution angle corresponds to the hole groove 301 on the outer wall of the sealing frame 3, the latch teeth 402 are connected to the outer wall of the connecting plate 401 by bolts, the injection pipe 2 passes through the cavity 5 and is slidably connected to the sealing frame 3, the gas chamber 501 is located in the cavity 5 and is annularly distributed on the inner wall of the cavity 5, the gas chamber 501 is loaded with high-pressure gas, the collar 6 is sleeved on the area where the injection pipe 2 is located in the cavity 5, one end of the connecting rod 601 is connected to the outer wall of the collar 6 by bolts, and the other end extends into the gas chamber 501 and is installed with a piston, and the air pressure sensor in the gas chamber 501 is electrically connected to the hydraulic cylinder in the support frame 1. When in use, the tank truck first moves to the feeding position, the empty support frame 1 descends and drives the sealing frame 3 and the injection pipe 2 to be embedded in the feeding port of the tank truck, and then the PLC controller cylinder 302 drives the connecting plate 401 to extend and abut against the inner wall of the feeding port, and at the same time controls the air pump to inflate the airbag 4 to expand it to fill the gap in the feeding port; during the injection process, when the tank truck descends, the sealing frame 3 and the injection pipe 2 slide together so that it can descend synchronously with the tank truck. On the contrary, when the air pressure in the tank truck pushes the sealing frame 3 away from the feeding port, the position is supported by the connecting rod 601 and high-pressure gas inside the sealing frame 3. If the pressure in the tank truck is too high and causes the sealing frame 3 to move upward, the connecting rod 601 in the cavity 5 will contract and squeeze into the gas chamber 501 to increase the pressure. When the pressure in the gas chamber 501 is greater than the set value, a signal is sent to control the hydraulic cylinder in the support frame 1 to push the sealing frame 3 to be embedded in the feeding port again for support.

If the pressure in the tank truck is too high and causes the sealing frame 3 to move upward, the connecting rod 601 in the cavity 5 will contract and squeeze into the gas chamber 501 to increase the pressure. When the pressure in the gas chamber 501 is greater than the set value, a signal is sent to control the hydraulic cylinder in the support frame 1 to push the sealing frame 3 to be embedded in the feeding port again for support.
