The entire device housing is moved to the target position by rolling wheels, then fixed by a self-locking mechanism, and the protective cover is opened by flipping the connector.
[0004] Currently, simple instrument testing equipment cannot test multiple packaging bags simultaneously. After testing one packaging bag, it is necessary to replace the packaging bag before testing can continue, resulting in low work efficiency. Utility Model Content
[0005] The technical problem that this utility model aims to solve in view of the above-mentioned prior art is that the current simple instrument testing equipment cannot simultaneously test multiple packaging bags. After the testing of one packaging bag is completed, the packaging bag needs to be replaced before testing can continue, resulting in low work efficiency.
[0006] To address the aforementioned problems, this utility model provides a device for testing the sealing performance of medical testing supplies packaging. The device includes a main body with a water tank embedded in its top. Multiple partitions divide the water tank into multiple water troughs. A groove is formed on the top wall of the main body directly above the partitions. A symmetrical lead screw and slide rod are rotatably connected to the inner wall of the groove. Moving blocks are fitted onto the surfaces of both the lead screw and slide rod, with one of the moving blocks threadedly connected to the lead screw. An air cylinder is installed within each moving block, and multiple air nozzles corresponding to the water troughs are equidistantly formed on the bottom wall of the air cylinder. The device has symmetrically fixed damping telescopic rods at both ends. The movable end of the damping telescopic rod is connected to a connecting plate with a handle. Multiple connectors that pass through the connecting plate and correspond to multiple air nozzles are installed on the connecting plate. A delivery pipe is threaded between the connector and the corresponding air nozzle. Multiple clamps that communicate with the connectors are connected to the bottom end of the connecting plate. An air inlet that connects to the connector is installed at the lower end of the clamp. A magnetic block is detachably connected to the bottom end of the clamp. An air inlet extending beyond the moving block is opened on the side end of the air cylinder. An air pump is fixedly connected to the side end of the device body, and the output end of the air pump is connected to the air inlet through an air pipe.
[0007] In the aforementioned sealing test device, multiple clamps are installed on the water tank to simultaneously test multiple packaging bags, thereby improving work efficiency.
[0008] As a further improvement of this application, a support plate is fixedly connected to the back of the device body, a servo motor is fixedly connected to the support plate, and the output end of the servo motor is connected to the lead screw.
[0009] As a further improvement of this application, a magnetic sheet is fixedly connected to the bottom end of the fixture, and the magnetic block and the magnetic sheet attract each other. A sealing ring is fixedly connected to the inner wall of the fixture.
[0010] As a further improvement of this application, multiple limiting grooves are installed at equal intervals on the bottom wall of the water tank, and the partition plate engages with the corresponding limiting groove.
[0011] As another improvement of this application, a pressure plate is snapped onto the top of the water tank, and multiple sets of limiting plates corresponding to the partition are fixedly connected to the inner wall of the pressure plate, and the pressure plate is engaged with the top of the partition.
[0012] As a further improvement to this application, a water outlet extending out of the device body is provided at the bottom side of the water tank, and a solenoid valve is installed inside the water outlet.
[0013] As a further improvement to this application, a controller for controlling the air pump, servo motor and solenoid valve is fixedly connected to the main body of the device.
[0014] In summary, the magnetic block is placed over the opening of the medical packaging bag to be tested, and then the bag opening is rolled up and placed over the magnetic block. At this point, the magnetic block and magnetic sheet are magnetically attracted and fixed together, and the medical packaging bag is clamped at the bottom of the fixture. At this time, the inflation nozzle inside the fixture is facing the opening of the packaging bag. Multiple packaging bags are installed on the corresponding fixtures in sequence. The servo motor is activated by the controller to drive the lead screw to rotate, thereby driving the moving block to move horizontally on the surface of the lead screw and slide bar, moving the packaging bag to a position directly above the water tank. Then, the side of the connecting plate is held by hand. Pull the handle down to move the packaging bag into the corresponding water tank via the extension and retraction adjustment of the damping telescopic rod. Then, turn on the air pump through the controller to deliver gas to the air cylinder inside the moving block through the air pipe. Then, through the inflation nozzles connected to the corresponding delivery pipes, inflate multiple packaging bags to check the sealing performance. If the packaging bag is qualified, the water in the tank will not fluctuate. If the sealing performance is not qualified, the packaging bag will leak air and produce obvious bubbles in the water tank. After the test, the packaging bag can be raised and moved horizontally outside the water tank for drainage. Attached Figure Description

[0024] The two embodiments of this application will be described in detail below with reference to the accompanying drawings.
[0025] First implementation method:
[0026] Figures 1-5 and Figure 7 This invention discloses a device for testing the sealing performance of medical testing supplies packaging. The device includes a main body 1, with a water tank 11 embedded in its top. Multiple partitions 12 are installed inside the water tank 11, dividing it into multiple water troughs. A groove 13 is formed on the top wall of the main body 1 directly above the partitions 12. A symmetrical lead screw 14 and a sliding rod 18 are rotatably connected to the inner wall of the groove 13. Moving blocks 5 are fitted onto the surfaces of both the lead screw 14 and the sliding rod 18, with one of the moving blocks 5 threadedly connected to the lead screw 14. An air cylinder is installed inside the moving block 5, and multiple air nozzles 15, corresponding to the water troughs, are equidistantly formed on the bottom wall of the air cylinder. The two ends of the moving block 5 are symmetrically fixed. A damping telescopic rod 6 is connected, and the movable end of the damping telescopic rod 6 is connected to a connecting plate 7 with a handle. Multiple connectors 20 are installed on the connecting plate 7 and are respectively connected to multiple air nozzles 15. A delivery pipe 8 is threaded between the connector 20 and the corresponding air nozzle 15. Multiple clamps 9 that communicate with the connectors 20 are connected to the bottom end of the connecting plate 7. An air inlet 19 connected to the connector 20 is installed at the lower end of the clamp 9. A magnetic block 10 is detachably connected to the bottom end of the clamp 9. An air inlet 3 extending to the outside of the moving block 5 is opened on the side end of the air cylinder. An air pump 2 is fixedly connected to the side end of the device body 1, and the output end of the air pump 2 is connected to the air inlet 3 through an air pipe 4.
[0027] A support plate 17 is fixedly connected to the back of the device body 1. A servo motor 16 is fixedly connected to the support plate 17, and the output end of the servo motor 16 is connected to the lead screw 14. A magnetic sheet 21 is fixedly connected to the bottom of the clamp 9, and the magnetic block 10 and the magnetic sheet 21 attract each other. A sealing ring is fixedly connected to the inner wall of the clamp 9. A controller for controlling the air pump 2, the servo motor 16 and the solenoid valve is fixedly connected to the device body 1.
[0028] The damping telescopic rod 6 adopts existing technology, and those skilled in the art shall select a suitable damping telescopic rod 6 from the existing technology for installation, such as: MISUMI GCTB6.
[0029] Working principle: The magnetic block 10 is placed over the opening of the medical packaging bag to be tested. The bag opening is then rolled up and placed over the magnetic block 10, at which point the magnetic block 10 and magnetic sheet 21 are magnetically attracted and fixed together (magnetic attraction stabilizes the bag opening sealing pressure at 0.2MPa±5%). The medical packaging bag is then clamped at the bottom of the clamp 9. The inflation nozzle 19 inside the clamp 9 faces the opening of the packaging bag. Multiple packaging bags are sequentially installed onto their corresponding clamps 9. The controller activates the servo motor 16, which drives the lead screw 14 to rotate, thereby driving the moving block 5 to move horizontally across the surfaces of the lead screw 14 and slide bar 18, moving the packaging bag... Position the bag directly above the water tank 11, then pull it down by holding the handle on the side of the connecting plate 7. Adjust the bag's position by extending and retracting the damping telescopic rod 6 to move it into the corresponding water tank. Then, turn on the air pump 2 through the air pipe 4 to deliver gas to the air cylinder inside the moving block 5. Inflate the bags through the inflation nozzles 19 connected to the multiple delivery pipes 8 to check the seal. If the bag is qualified, the water in the tank will not fluctuate. If the seal is not qualified, the bag will leak air and produce obvious bubbles in the tank. After the test, the bag can be raised and moved horizontally outside the water tank 11 to drain.
[0030] This invention improves work efficiency by setting multiple clamps 9 on the water tank 11 to simultaneously inspect multiple packaging bags.
[0031] Second implementation method:
[0032] Figure 1 and Figure 6 The bottom wall of the water tank 11 is shown to have multiple limiting grooves 22 installed at equal intervals, and the partition 12 is engaged with the corresponding limiting groove 22. The top of the water tank 11 is engaged with a pressure plate 23, and the inner wall of the pressure plate 23 is fixedly connected with multiple sets of limiting plates 24 corresponding to the partition 12, and the pressure plate 23 is engaged with the top of the partition 12. The bottom side of the water tank 11 has an outlet extending to the outside of the device body 1, and a solenoid valve is installed in the outlet.
[0033] Working principle: Based on the number of packaging bags to be tested at one time, the corresponding number of partitions 12 can be selectively inserted into the limiting grooves 22 in the water tank 11. Then, the pressure plate 23 is engaged with the top of the water tank 11, and the corresponding limiting plate 24 is engaged with the corresponding partition 12 to reinforce the partition 12. At this time, the water tank 11 is divided into water tanks with the same number of packaging bags, which facilitates independent testing of the packaging bags and allows for better observation of water surface fluctuations to determine whether the packaging bags are qualified. After testing, the partitions 12 can be removed, and then the solenoid valve is opened by the controller to drain the water in the water tank 11 from the drain outlet.
[0034] The design of the detachable partition 12 inside the water tank 11 makes it easy to adjust the number of water tanks inside the water tank 11 according to the number of packaging bags to be tested simultaneously.
[0035] In light of current practical needs, the above-described embodiments adopted in this application are not limited to these. Any changes made within the scope of knowledge possessed by those skilled in the art without departing from the concept of this application still fall within the protection scope of this utility model.
