[0023] The present application will be further described in detail below with reference to the accompanying drawings and embodiments.

[0024] Reference Figures 1 to 4 This application provides a quality inspection device for the production of double-mouth three-dimensional bags, including a holding box 1, inside which a three-dimensional bag 4 is placed. A protective component 2 is provided on the top of the holding box 1, and a detection component 3 is provided on the side of the holding box 1. A bag opening 5 is fixedly installed on the top of the three-dimensional bag 4, and a first sealing cover 6 is screwed to the outside of the right bag opening 5. The detection component 3 includes a rigid tube 36, and a second sealing cover 35 is rotatably connected to the outside of the rigid tube 36. The second sealing cover 35 is screwed to the outside of the left bag opening 5. The rigid tube 36 is inserted into the inside of the bag opening 5, and a pressure sensor 38 is fixedly installed at the bottom of the rigid tube 36. The pressure sensor 38 is located inside the three-dimensional bag 4.

[0025] An equipment box 31 is fixedly installed on the left side of the container 1. Inside the equipment box 31 are a battery and an air pump. A flexible hose 33 is fixedly installed between the air pump's outlet and a rigid pipe 36. A connecting groove 37 is formed on the side wall of the rigid pipe 36, located inside the three-dimensional bag 4. A data cable 34 is fixedly installed inside the rigid pipe 36. A controller 32 is fixedly installed on the left side of the equipment box 31, and the controller 32 is electrically connected to a pressure sensor 38 via the data cable 34. The battery is electrically connected to the air pump and the controller 32. The air pump's inlet is located below the equipment box 31.

[0026] In the embodiment, when detecting the three-dimensional bag 4, the right bag opening 5 is sealed by the first sealing cover 6, the hard pipe 36 is inserted into the three-dimensional bag 4 from the left bag opening 5 together with the pressure sensor 38, and after insertion, the second sealing cover 35 is fixed outside the left bag opening 5 by rotating the second sealing cover 35, thus completing the sealing of the left bag opening 5. Then, the gas pump is started to pass gas into the hard pipe 36 through the hose 33, and into the three-dimensional bag 4 through the communication groove 37. After the gas is passed in, the internal pressure is detected by the pressure sensor 38. After the gas is passed in completely, the internal pressure change is detected by the pressure sensor 38, so that whether the three-dimensional bag 4 leaks can be known.

[0027] With reference to Figures 1 to 4 In one aspect of the embodiment, the protection assembly 2 includes a protection cover 21 which is screwed on the top of the containing box 1. The three-dimensional bag 4 is located between the containing box 1 and the protection cover 21. The containing box 1 is made of transparent acrylic plate.

[0029] In the embodiment, when detecting, the three-dimensional bag 4 is placed in the containing box 1, and the protection cover 21 is covered on the top of the containing box 1. The three-dimensional bag 4 is fixed by adsorbing the magnet block 22 on the iron plate 23. After fixing, water is injected into the containing box 1. After injection, gas is passed into the three-dimensional bag 4. Whether the three-dimensional bag 4 leaks can be known by observing whether bubbles are generated on the outer surface of the three-dimensional bag 4. The specific leaking position can be known. The maximum pressure that the three-dimensional bag 4 can bear can be detected by continuously passing gas into the three-dimensional bag 4 and through the pressure change of the pressure sensor 38, so as to detect the strength of the three-dimensional bag 4.

After insertion, the second sealing cover 35 is fixed outside the left bag opening 5 by rotating the second sealing cover 35, thus completing the sealing of the left bag opening 5. At this time, the gas pump in the equipment box 31 is started. The gas inlet of the gas pump is located below the equipment box 31. The ambient air is extracted. After the air is pressurized by the gas pump, the air is passed into the hard pipe 36 through the hose 33, and then enters the three-dimensional bag 4 through the communication groove 37 in the side wall of the hard pipe 36. After the gas enters, the pressure sensor 38 starts to detect the internal pressure of the three-dimensional bag 4. When the gas is passed in completely, the internal pressure change is detected by the pressure sensor 38, so that whether the three-dimensional bag 4 leaks can be judged.

[0032] When the protection assembly 2 is used for detection, the three-dimensional bag 4 is placed inside the containing box 1, and then the protection cover 21 is covered on the top of the containing box 1, the magnet block 22 on the front of the protection cover 21 is adsorbed on the iron plate 23 on the front of the containing box 1, so as to fix the three-dimensional bag 4, after fixing, water is injected into the containing box 1, then gas is introduced into the three-dimensional bag 4, at this time, whether the three-dimensional bag 4 leaks and the specific leakage position can be judged by observing whether bubbles are generated on the outer surface of the three-dimensional bag 4, and the gas is continuously introduced into the three-dimensional bag 4, the maximum pressure that the three-dimensional bag 4 can withstand can be detected by monitoring the pressure change through the pressure sensor 38, so as to evaluate the strength of the three-dimensional bag 4.
