Description

Technical Field

[0001] This utility model relates to the field of detection device technology, and in particular to a packaging bag sealing detection device. Background Technology

[0002] In the packaging industry, the sealing quality of packaging bags is an important indicator for measuring the integrity, protection, and aesthetics of product packaging. Traditional packaging bag sealing inspection methods mostly rely on manual observation and manual testing. This method is not only inefficient but also easily affected by human factors, leading to inaccurate test results. At the same time, some destructive testing methods, such as cutting and tearing, although they can directly reflect the sealing strength, can cause irreversible damage to the packaging bag, increasing production costs and waste.

[0003] Therefore, in order to address this problem, this utility model provides a packaging bag sealing detection device. Utility Model Content

[0010] Preferably, the testing water tank is provided with handles on both sides, and the handles are used for lifting.

[0011] Compared with the prior art, the present invention provides a packaging bag sealing detection device, which has the following beneficial effects:

[0012] 1. This packaging bag sealing inspection device utilizes the principles of water level change and magnetic induction, combined with a sliding pressing frame and a colored detection liquid. This device enables non-destructive testing of packaging bag seals. The interaction between the water level change in the sensing tube and the induction magnet directly reflects the tightness of the seal, while the pressing frame ensures uniform pressure on the bag during testing. This design not only improves accuracy but also avoids the waste and contamination caused by traditional destructive testing methods. Furthermore, the testing process is simple and quick, significantly improving efficiency.

[0013] 2. The packaging bag sealing detection device is firmly fixed to the detection water tank by fasteners to prevent it from shaking or falling off during the detection process, thus ensuring the accuracy of the detection results. At the same time, the top of the detection water tank is designed with a cover groove that matches the sealing cap, which can form a closed detection environment to prevent leakage of detection liquid or entry of external contaminants.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0019] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0020] Reference Figures 1-3 A packaging bag sealing detection device mainly includes a detection water tank 1. On the side of the detection water tank 1, a sensing tube 2 is set for observing and detecting water level changes. The top of the detection water tank 1 is designed with a movable sealing cover 3 to seal the detection environment and prevent leakage of the detection liquid. The bottom and top of the sensing tube 2 are respectively equipped with a first sensing magnet 4 and a second sensing magnet 5, which work together to detect water level changes. The inner wall of the sensing tube 2 is equipped with a sliding sensing float 6, which moves up and down with the water level change. To facilitate the observation of the water level, a scale strip 7 is opened on the side of the sensing tube 2. The sensing tube 2 is connected to the detection water tank 1 through a connecting pipe 8. A sensing valve 9 is installed on the connecting pipe 8 to control the flow of water. In addition, a sliding pressing frame 10 is installed inside the detection water tank 1. In use, first place the packaging bag to be tested into the testing water tank 1, then press it down with the pressing frame 10. Next, pour the colored testing liquid into the testing water tank 1. If the packaging bag is not sealed tightly, the testing liquid will seep in from the seal. By observing the water level change in the sensing tube 2 and the interaction of the sensing magnet, the sealing condition of the packaging bag can be easily detected. This device achieves non-destructive testing of the packaging bag seal through the principle of water level change and magnetic induction, improving the accuracy and efficiency of the test.

[0021] In this device, a fixing component 11 is provided on the side of the sensing tube 2, and the side of the fixing component 11 is installed on the detection water tank 1. The function of the fixing component 11 is to firmly fix the sensing tube 2 on the detection water tank 1, preventing it from shaking or falling off during the detection process, which would affect the accuracy of the detection results. The use of the fixing component 11 ensures that the connection between the sensing tube 2 and the detection water tank 1 is firm and reliable, and improves the stability and durability of the detection device.

[0022] In particular, a cover groove 101 is provided on the top of the test water tank 1. The shape and size of the cover groove 101 are perfectly matched with the sealing cover 3. The sealing cover 3 can be tightly closed on the cover groove 101 to form a closed test environment, preventing leakage of test liquid or entry of external contaminants. The tight fit between the cover groove 101 and the sealing cover 3 ensures the sealing of the inside of the test water tank 1, improving the accuracy and safety of the test.

[0023] In this design, two slots 102 are symmetrically provided on the inner wall of the testing water tank 1, and a locking strip matching the slots 102 is provided on the side of the pressing frame 10. When the pressing frame 10 is placed into the testing water tank 1, the locking strip will engage with the slots 102, allowing the pressing frame 10 to slide up and down in a fixed position while remaining stable. The matching design of the slots 102 and the locking strip makes the sliding of the pressing frame 10 in the testing water tank 1 more stable and reliable, improving the convenience and accuracy of the testing operation.

[0024] The pressing frame 10 includes a pressing frame 1002 and a frame handle 1001 for easy gripping and operation by the user. On both sides of the pressing frame 1002, several pressing plates 1003 are evenly arranged. These pressing plates 1003 can apply pressure to the packaging bag evenly to test the strength of its seal. The design of the pressing frame 10 makes the pressure on the packaging bag more uniform and controllable, improving the accuracy and reliability of the seal test.

[0025] On both sides of the testing tank 1, we have installed a handle 12 for easy gripping and lifting of the entire testing device. The design of the handle 12 makes the testing device easier to move and operate, improving the efficiency of the testing work. The addition of the handle 12 enhances the portability and operability of the testing device, allowing users to easily move the device to the required location and perform testing operations.

[0026] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
