Description

Technical Field

[0001] This utility model relates to the field of packaging bag processing technology, and in particular to a leak-proof detection device for food packaging bag processing. Background Technology

[0002] Gas-filled packaging is a common food packaging method, frequently used for puffed foods such as popular potato chips in supermarkets. Gas-filled packaging involves vacuuming the packaging bag and then filling it with a single gas, such as nitrogen, carbon dioxide, or oxygen, or a mixture of two or three gases. Nitrogen, being an inert gas, acts as a filler, maintaining positive pressure inside the bag to prevent outside air from entering and protecting the food. However, during the gas-filling and sealing process, leaks can occur, allowing internal gas to escape and external gases carrying bacteria and other substances to enter the bag. This can affect the proper preservation of the product inside, necessitating testing of the packaging bag's seal.

[0003] Currently, most methods for testing the sealing of packaging bags involve manually squeezing the bags or immersing them in water to observe for air bubbles. This method is not only inefficient but also requires a lot of labor and is very inconvenient.

[0004] Therefore, it is necessary to provide a leak-proof detection device for food packaging bag processing to solve the above-mentioned technical problems. Utility Model Content

[0015] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0016] First Embodiment Please refer to the following: Figure 1 , Figure 2 , Figure 3 ,in, Figure 1 A schematic diagram of the first embodiment of a leak-proof detection device for food packaging bags provided by this utility model; Figure 2 for Figure 1 The diagram shows the structure of the detection frame. Figure 3 for Figure 1 The diagram shows another perspective of the structure.

[0017] A leak-proof detection device for food packaging bag processing includes: a conveying assembly 1; The feeding component 3 is disposed on one side of the conveying component 1; Detection frame 4 is disposed on the outer side of the conveying assembly 1; An ultrasonic leak detector 8 is disposed on the inner side of the detection frame 4; The clamping assembly 5 is respectively disposed on both sides of the detection frame 4.

The second drive telescopic member 51 is fixedly installed inside the side of the detection frame 4. The pressure sensor 52 is fixedly installed on the moving end of the second drive telescopic member 51 and the clamping plate 53 is fixedly installed on the side of the pressure sensor 52.

[0018] An object sensor is provided on the inner side of the detection frame 4. When the packaging bag moves to the bottom of the ultrasonic leak detector 8, the controller 7 can control the second drive telescopic component 51 to automatically extend and then be detected by the ultrasonic leak detector 8.

[0019] The conveying assembly 1 includes a conveying frame 11, a drive motor 12, two rotating shafts 13, and a conveyor belt 14. The two rotating shafts 13 are rotatably connected to both ends of the inner side of the conveying frame 11, the drive motor 12 is fixedly installed on one side of the conveying frame 11, and the output end of the drive motor 12 is fixedly installed on one end of one of the rotating shafts 13. The conveyor belt 14 is sleeved on the outer side of the two rotating shafts 13.

[0020] When in use, the drive motor 12 drives one of the rotating shafts 13 to rotate, and the rotating shaft 13 drives the conveyor belt 14 to rotate, thereby transporting the packaging bags that need to be inspected.

[0021] The feeding assembly 3 includes a side plate 31, a first driving telescopic member 32, and a feeding plate 33. The side plate 31 is fixedly installed on one side of the conveying frame 11, the second driving telescopic member 32 is fixedly installed inside the side plate 31, the feeding plate 33 is fixedly installed on the moving end of the first driving telescopic member 32, and a feeding frame 2 is fixedly installed on the other side of the conveying frame 11.

[0022] An object sensor is provided on the side of the feeding plate 33 near the conveying component 1. When the leaking packaging bag moves to the side of the feeding plate 33, the first drive telescopic component 32 will extend and push the packaging bag to the top of the feeding frame 2 through the feeding plate 33, and then feed it.

[0023] The controller 7 is fixedly installed on the top of the detection frame 4.

[0024] The controller 7 is electrically connected to the drive motor 12, the first drive telescopic component 32, the second drive telescopic component 51, the pressure sensor 52, and the ultrasonic leak detector 8. When in use, the controller 7 can control the drive motor 12, the first drive telescopic component 32, the second drive telescopic component 51, the pressure sensor 52, and the ultrasonic leak detector 8 respectively.

[0025] An adjustment component 6 is provided on the top of the detection frame 4. The adjustment component 6 includes a fixing ring 61, a locking screw 62, and an adjustment rod 63. The fixing ring 61 is fixedly installed inside the top of the detection frame 4. The adjustment rod 63 is slidably connected to the inner side of the fixing ring 61. The locking screw 62 is threadedly connected to the inside of the side of the fixing ring 61.

[0026] One end of the locking screw 62 abuts against the side of the adjusting rod 63, and the bottom of the adjusting rod 63 is fixedly installed on the top of the ultrasonic leak detector 8.

[0027] When in use, the adjusting rod 63 slides up and down on the inner side of the fixing ring 61 to adjust the height of the ultrasonic leak detector 8, so as to test packaging of different sizes. After adjusting to the appropriate position, the user rotates the locking screw 62 so that one end of the locking screw 62 abuts against the side of the adjusting rod 63, thereby fixing the adjusting rod 63.

[0028] The working principle of the leak-proof detection device for food packaging bags provided by this utility model is as follows: During use, the conveying assembly 1 transports the packaging bag to the inner side of the detection frame 4. At this time, the controller 7 controls the extension of the two second drive telescopic components 51, thereby causing the two clamping plates 53 to clamp and squeeze the packaging bag. During the squeezing process, the pressure sensor 52 monitors the magnitude of the clamping force in real time and feeds the data back to the controller 7 to ensure that the clamping force is within a suitable range and to avoid damage to the packaging bag due to excessive clamping force. If there is a leak in the packaging bag, the internal gas leakage will generate ultrasonic waves of a specific frequency, which can be captured by the ultrasonic leak detector 8. The sound wave signal is converted into an electrical signal and transmitted to the controller 7. After analyzing and processing the electrical signal, the controller 7 determines whether the packaging bag is leaking. After the detection is completed, the controller 7 controls the second drive telescopic component 51 to retract and release the clamping plate 53. At this time, the conveying component 1 conveys the packaging bag. When the packaging bag leaks air, the first drive telescopic component 32 in the unloading component 3 extends and pushes the unloading plate 33 to push the detected packaging bag into the unloading frame 2. When the packaging bag does not leak air, the packaging bag will be conveyed by the conveying component 1 to one end of the conveying component 1, thus completing one detection process.

[0029] Compared with related technologies, the leak-proof detection device for food packaging bags provided by this utility model has the following advantages: The conveying component 1, the unloading component 3, the detection frame 4, the clamping component 5, and the ultrasonic leak detector 8 work together to automatically transport the packaging bags to be tested during use. Then, the clamping component 5 and the ultrasonic leak detector 8 work together to automatically detect leaks in the packaging bags. This eliminates the need for manual testing by staff, which not only increases testing efficiency but also reduces labor costs and makes the operation more convenient.

[0030] Second Embodiment Please refer to the following: Figure 4 Based on the first embodiment of this application which provides a leak-proof detection device for food packaging bag processing, the second embodiment of this application proposes another leak-proof detection device for food packaging bag processing. The second embodiment is merely a preferred embodiment of the first embodiment, and the implementation of the second embodiment will not affect the separate implementation of the first embodiment.

[0031] Specifically, the second embodiment of this application provides a leak-proof detection device for food packaging bag processing, which differs in that the leak-proof detection device for food packaging bag processing also includes two guide components 9. The two guide components 9 are respectively disposed on both sides of the conveying component 1. Each of the two guide components 9 includes a fixed plate 91, a threaded rod 92, a guide plate 93, and a rotating handle 94. The threaded rod 92 is threadedly connected to the inside of the fixed plate 91, the guide plate 93 is rotatably connected to one end of the threaded rod 92, and the rotating handle 94 is fixedly installed on the other end of the threaded rod 92.

[0032] The working principle of the leak-proof detection device for food packaging bags provided by this utility model is as follows: During use, rotating the handle 94 drives the threaded rod 92 to rotate. Since the threaded rod 92 is threadedly connected to the fixed plate 91, the threaded rod 92 will move axially, thereby driving the guide plate 93 to adjust its position in the horizontal direction. When the packaging bag moves with the conveyor belt 14, the guide plates 93 on both sides can limit the offset range of the packaging bag, keeping it in the center position of the conveying assembly 1, ensuring accurate entry into the detection frame 4. After adjusting the position of the guide plate 93, the threaded engagement between the threaded rod 92 and the fixed plate 91 can stably fix the guide plate 93, preventing displacement during the detection process.

[0033] Compared with related technologies, the leak-proof detection device for food packaging bags provided by this utility model has the following advantages: By adding the guide component 9, the guide plate 93 can correct the conveying trajectory of the packaging bag in real time during use, preventing the clamping component 5 from failing to clamp accurately or the ultrasonic leak detector 8 from deviating due to offset, thus ensuring the continuity of the detection process.

[0034] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
