[0031] In order to further explain the technical solution of the present invention, the present invention will be elaborated in detail below through specific embodiments.

[0032] Refer to Figures 1-5 As shown, the present invention discloses a sealing test mechanism for a waterproof bag body, including a frame 1, a water storage bucket 2, a driving device 3 installed on the frame 1, a sealing component 4, and an inflatable tube 5;

[0033] The water storage bucket 2 is made of a transparent material, and a through hole 21 for the bag body to enter is provided on its upper end surface, and a fixing ring 22 for fixing the peripheral edge of the bag body opening is provided on the periphery of the through hole 21;

[0034] The driving device 3 is arranged above the through hole 21;

[0035] The sealing component 4 is installed at the output end of the driving device 3 and is driven by the driving device 3 to move up and down to achieve active contact with the fixing ring 22; the sealing component 4 is provided with an inflation hole 411;

[0036] The output end of the inflatable tube 5 is inserted into the inflation hole 411, and its input end is used to connect to an inflation device.

[0037] Through the above solution, when the present invention conducts a sealing test, a certain amount of water is contained in the water storage bucket 2, and the bag body to be tested is placed in the bucket. The peripheral edge of the bag body opening is folded back and sleeved on the fixing ring 22, and then the driving device 3 drives the sealing component 4 to descend to press the opening of the bag body and seal the opening of the bag body. Then, the inflatable tube 5 inflates the inner bag body; since there is water in the water storage bucket 2, when there is a leak gap in the bag body, continuous bubbles will be generated at the gap during inflation, which can be quickly observed by the employee through the transparent water storage bucket 2. Thus, it is possible to judge the sealing performance of the bag body by whether there are bubbles, so as to quickly test the sealing performance of the bag body, and it has the advantages of reducing labor intensity, simple operation, and high efficiency.

[0038] The following shows specific embodiments of the present invention.

[0039] The upper end surface of the fixing ring 22 is provided with a plurality of anti-slip grooves 221, which can increase the friction between the bag body and the fixing ring 22, thereby better fixing the bag body.

[0040] The fixing ring 22 is integrally formed with the upper cover 23 of the water storage barrel 2, and the upper cover 23 is detachably connected to the main body of the water storage barrel 2, so that fixing rings 22 of different sizes can be replaced to match different bags to be tested.

[0041] The driving device 3 is a vertically arranged cylinder.

[0042] The sealing assembly 4 comprises a pressing plate 41 driven by the driving device 3, and a buffer plate 42 attached to the lower surface of the pressing plate 41, the buffer plate 42 is made of elastic material, and the inflation hole 411 is arranged on the pressing plate 41 and penetrates the buffer plate 42. The buffer plate 42 on the lower surface of the pressing plate 41 can prevent the pressing plate 41 from directly contacting the bag body and causing wear, thereby ensuring that the bag body will not be damaged during testing, and the buffer plate 42 made of elastic material can provide a better sealing effect after pressing the bag body, preventing air leakage from the gap between the sealing assembly 4 and the buffer plate 42 during inflation. In this embodiment, the buffer plate 42 is made of silicone.

[0043] Furthermore, the sealing assembly 4 further comprises a connecting plate 43 mounted at the output end of the driving device 3, and a plurality of springs 44 arranged between the connecting plate 43 and the pressing plate 41; the connecting plate 43 is provided with a clearance hole 431 opposite to the inflation hole 411, for making way for the inflation tube 5. The spring 44 can buffer the pressure output by the driving device 3, further preventing the sealing assembly 4 from crushing the opening of the bag body.

[0044] An air pump 6 is installed on the frame 1 , and the air pump 6 is connected to the input end of the inflation tube 5 .

[0045] Furthermore, the air pump 6 is provided with a pressure gauge 61 for real-time monitoring of the output air pressure.

[0046] A control panel 7 is disposed on the side of the frame 1 , and a display screen 71 and operation buttons 72 are disposed on the control panel 7 .

[0047] The above embodiments and drawings do not limit the product form and style of the present utility model. Any appropriate changes or modifications made by ordinary technicians in the relevant technical field should be deemed to be within the patent scope of the present utility model.
