At this time, it should be ensured that the pressing plate 32 also presses the bottle cap tightly against the gas distributor nozzle 22 to prevent gas leakage from the connection between the bottle cap and the gas distributor nozzle 22, and introduces gas into the gas distributor 2 from the air inlet 21. After observing that the air pressure detected by the air pressure detector 4 reaches the specified air pressure, stop ventilation, and then if the detected air pressure can be maintained within the specified time, the bottle cap has good sealing performance, otherwise on the contrary, the detection efficiency is effectively improved.

[0022] Furthermore, in a specific implementation, a mounting plate 5 is horizontally rotatably connected to the above-mentioned base 1 provided in an embodiment of the utility model, and a plurality of gas distributors 2 are provided. The plurality of gas distributors 2 are all fixed on the mounting plate 5, and the plurality of gas distributors 2 are centrally symmetrically arranged with the rotation center of the mounting plate 5. It should be noted that it should be ensured that the plurality of gas distributors 2 can be rotatably shifted to directly below the pressing mechanism 3 so that the pressing force is stable. When in use, the plurality of gas distributors 2 can be used alternately, with one of the gas distributors 2 being in the detection position, and the remaining gas distributors 2 being in an idle position for bottle cap installation operations, thereby further improving work efficiency.

[0023] Furthermore, in a specific implementation, the above-mentioned gas separation nozzles 22 provided in the embodiment of the utility model are provided with a plurality, and the plurality of gas separation nozzles 22 are evenly distributed on the gas separation plate 2. Specifically, the plurality of gas separation nozzles 22 are connected to the air inlet 21 through the gas separation branch holes 23, so that the sealing of a plurality of bottle caps can be detected at the same time.

[0024] Furthermore, in a specific implementation, the above-mentioned limit columns 33 provided in the embodiment of the utility model are provided in plurality, and the plurality of limit columns 33 act evenly on the upper surface of the gas distribution plate 2. It should be noted that the setting position of the limit column 33 should avoid the position of the gas distribution nozzle 22 to avoid interference between the limit column 33 and the gas distribution nozzle 22, so that the limit column 33 can stably act on the gas distribution plate 2.

[0025] Furthermore, in a specific implementation, the above-mentioned limiting column 33 provided in the embodiment of the utility model is provided on the pressing plate 32 with an adjustable height.

The processor detects the air pressure and performs threshold judgment to control the signal light and the air source. Specifically, when the air pressure sensor detects that the air pressure in the air distribution disk 2 has reached the specified air pressure, the processor first controls the air source to stop ventilation and waits for a specified time. The air pressure sensor detects the air pressure in real time. If the air pressure value can be maintained within the specified time, the control signal light turns on green, otherwise the red light turns on.
