[0020] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific embodiments. However, the following embodiments are only preferred embodiments of the present invention and are not exhaustive. Based on the embodiments in the implementation manner, other embodiments obtained by those skilled in the art without making any creative efforts shall fall within the scope of protection of the present invention.

[0021] Example

[0022] Please refer to Figure 1-Figure 5 As shown, the utility model provides a metal packaging barrel sealing detection device, including a water storage tank 1, a plurality of arc-shaped detection chambers 2 are opened inside the water storage tank 1, and adjacent arc-shaped detection chambers 2 are connected by a connecting chamber 16, so that the water stored in the arc-shaped detection chambers 2 can flow. A water outlet 14 and a water inlet 13 are provided on one side of the water storage tank 1, and the water in the arc-shaped detection chamber 2 can be replaced and replenished through the water inlet 13 and the water outlet 14.

[0023] like Figure 1-Figure 5 As shown, a receiving groove 3 is provided on the rear side of the arc-shaped detection chamber 2, and a rectangular column 4 is fixed on the rear side of the water tank 1. The rectangular column 4 is located directly behind the receiving groove 3, and the number of rectangular columns 4 is the same as the number of arc-shaped detection chambers 2. A guide groove 7 is provided on the front side of the rectangular column 4. A vertically placed guide round rod 6 is fixed inside the guide groove 7. An L-shaped lifting block 5 is provided inside the guide groove 7 and is sleeved on the outside of the guide round rod 6. The telescopic end of the L-shaped lifting block 5 extends into the receiving groove 3 and fits with the three side walls of the receiving groove 3, and a packaging barrel placement rack 11 is fixed to the bottom end of the vertical end of the L-shaped lifting block 5. The packaging barrel placement rack 11 has two arc rods, which fit with the inner wall of the arc-shaped detection chamber 2. Through the fit between the L-shaped lifting block 5 and the receiving groove 3 and the fit between the packaging barrel placement rack 11 and the inner wall of the arc-shaped detection chamber 2, when the metal packaging barrel is placed on the packaging barrel placement rack 11, it will not be easily bent due to gravity and thrust. Figure 2 As shown, the outer side of the guide rod 6 is provided with a spring 15 located below the crossbar of the L-shaped lifting block 5. The elastic force of the spring 15 can push the L-shaped lifting block 5 upward. In actual use, the spring 15 will push the packaging barrel placement rack 11 above the water surface.

[0024] like Figure 1 and Figure 2 As shown, a support plate 8 is fixed to the top of the rectangular column 4, and the other end of the support plate 8 extends directly above the water tank 1. A mounting hole is opened at one end of the support plate 8 located above the water tank 1, and a telescopic cylinder 9 is fixed in the mounting hole. The telescopic end of the telescopic cylinder 9 faces downward, and a pressure plate 10 is fixed to the telescopic end of the telescopic cylinder 9. The pressure plate 10 is horizontally located directly above the water tank 1;

[0025] like Figure 1 and Figure 5 As shown, the water tank 1 is provided with an air pipe 12 on one side, which is embedded in the bottom wall of the water tank 1. One end of the air pipe 12 passes through the water tank 1 and is exposed outside the water tank 1 and is connected to the air supply equipment. An electromagnetic air outlet valve 17 is fixed in the middle of the packaging barrel rack 11, and the top surface of the electromagnetic air outlet valve 17 is coplanar with the top surface of the packaging barrel rack 11. The air pipe 12 and the electromagnetic air outlet valve 17 are connected by an air supply hose 18.

[0026] Specific working principle:

[0027] When inspecting uncovered barrels, barrels of different heights are placed upside down on the packaging barrel placement rack 11 with the barrel mouth facing downward, and the telescopic cylinder 9 is started. The telescopic cylinder 9 pushes the pressing plate 10 downward. In the process of the pressing plate 10 moving downward, the pressing plate 10 first contacts the bottom of the higher barrel. As the pressing plate 10 moves downward, the higher barrel is immersed in the water first. When the pressing plate 10 contacts the bottom of the last barrel, the pressing plate 10 continues to move downward to press all the barrels into the water, so that the entire barrel is immersed in water, thereby realizing the sealing test of the metal packaging barrel. Since subsequent operations such as cleaning and painting are still required, the method of using water to test the sealing of the metal packaging barrel will not cause the packaging barrel to rust or affect its subsequent performance.

[0028] Since water will enter a part of the barrel during the inspection of the uncovered barrel, it is impossible to detect whether the part is sealed. Therefore, when inspecting the uncovered barrel, the mouth of the uncovered barrel is turned upside down above the electromagnetic air outlet valve 17. After the barrel is completely immersed in water, air is inflated into the interior of the electromagnetic air outlet valve 17 through the air supply pipe 12 for a certain period of time until all the barrels can discharge bubbles from the bottom. After the inflation is completed, it is left to stand for a period of time. If there are still bubbles in a barrel, it means that the barrel is not sealed.

[0029] When testing a covered metal packaging barrel, place the metal barrel upright and immerse the entire metal packaging barrel in water using the telescopic cylinder 9 and the pressing plate 10 to observe whether bubbles are generated.

[0030] The above shows and describes the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely preferred examples of the present invention and are not intended to limit the present invention. Various changes and improvements may be made to the present invention without departing from the spirit and scope of the present invention, and such changes and improvements fall within the scope of the present invention. The scope of protection claimed in the present invention is defined by the appended claims and their equivalents.
