Description

Technical Field

[0001] This utility model belongs to the field of packaging testing technology, specifically relating to a packaging container immersion test detection device. Background Technology

[0002] The standard for basic performance testing and evaluation of large transport packaging includes assessing the adaptability of transport packaging to the transport environment and its ability to protect the contents. This standard stipulates that the leakage test of the packaging box or container requires immersing the test sample in water to a depth of up to 750 mm for no less than 1 hour. After immersion, the sample is removed, the parts to be opened are wiped dry, and the water marks inside the box or container and the leakage situation are observed to determine whether the packaging box or container is qualified.

[0003] For large packaging boxes, they may be subjected to several tons of buoyancy during immersion tests. Due to the variation in the size of the packaging containers, the pressure fixtures used for immersion tests are required to have the ability to adjust various variables such as immersion height, pressing width, and length. The new testing device needs to solve the inconvenience caused by manually loading weights to press the packaging and unloading, and also meet the problem of continuously testing samples without the need to drain water.

The pressing plate is pressed and connected to the packaging box. The lead screw drives the packaging box to move up and down through bidirectional control by an external control unit.

[0008] Furthermore, the pressing plate includes a first L-shaped pressing plate and a second L-shaped pressing plate. The first L-shaped pressing plate is provided with a plurality of flange connection holes at intervals. The first L-shaped pressing plate is connected to the flange through the flange connection holes according to the length of the packaging box. The two ends of the first L-shaped pressing plate are provided with elongated holes.

Detailed Implementation

[0019] The present invention will be further described in detail below through specific embodiments. The following embodiments are only descriptive and not limiting, and should not be used to limit the protection scope of the present invention.

[0020] A packaging container immersion test detection device is characterized by: including a water tank 1, two U-shaped connecting beams 2 symmetrically spaced on the outside of the water tank 1, a horizontal plate 3 fixedly installed between the U-shaped connecting beams 2, a screw linkage mechanism installed on the horizontal plate 3, the lower end of the screw linkage mechanism being connected to a packaging box 9, and an inlet and outlet at the bottom of the water tank 1 for convenient water filling operation, etc.

[0021] The lead screw linkage mechanism includes a drive motor 4 and a lead screw jack 5. The drive motor 4 is fixedly installed on the horizontal plate 3. The lead screw jacks 5 are symmetrically spaced on the horizontal plate 3. The lead screw jacks 5 are connected to the drive motor 4 through a coupling 15 and an optical shaft 14. The lower end of the lead screw jack 5 is connected to a lead screw 6. The bottom end of the lead screw 6 is connected to a pressing plate 8 through a flange 7. The pressing plate 8 is pressed and connected to the packaging box 9. The lead screw is bidirectionally controlled by an external control unit to drive the packaging box to move up and down.

[0022] This invention achieves the function of immersion and pressing of packaging containers through a screw linkage mechanism, replacing the labor-intensive, inefficient, and unsafe operation of manually loading and unloading weights on packaging containers; at the same time, it can continuously change packaging sample boxes for testing without draining water, directly pressing the box to the bottom of the water, thus improving testing efficiency.

[0023] The pressing plate 8 includes a first L-shaped pressing plate 11 and a second L-shaped pressing plate 10. The first L-shaped pressing plate 8 is provided with a plurality of flange connection holes 12 at intervals. The first L-shaped pressing plate 11 is connected to the flange 7 through the flange connection holes 12 according to the length of the packaging box 9. The two ends of the first L-shaped pressing plate 11 are provided with elongated holes 13. The second L-shaped pressing plate 10 is connected to the packaging box 9 through the elongated holes 13 according to the width of the packaging box 9. The first L-shaped pressing plate 11 and the second L-shaped pressing plate 10 are respectively connected and attached to the front, back, left and right surfaces of the packaging box 9.

[0024] This invention utilizes a screw linkage mechanism to enable the pressing plate to adjust its width and length, facilitating the use of packaging boxes of different sizes and making it widely applicable. At the same time, it can completely enclose the packaging container underwater, avoiding the risk of the water tank escaping from the side due to strong buoyancy during the screw's ascent.

[0025] The water tank 1 is integrally welded to the U-shaped connecting beam 2, saving space and avoiding the problems of large space and complex structure of the split structure.

[0026] The working principle of this utility model is as follows:

[0027] Connect the pressing plate of this utility model to the packaging box to be tested, start the drive motor and control the downward movement of the screw jack through the external control unit to completely immerse the packaging box in the water tank to complete the immersion test. After the immersion time requirement is reached, the screw jack moves in the reverse direction to drive the packaging box to move upward, so that the staff can take off the packaging box for inspection.

[0028] When the packaging box has different sizes, the connection position between the pressing plate and the packaging box can be adjusted through the elongated hole and the flange connection hole to achieve different lengths and widths.
