Description

Technical Field

[0001] The invention relates to the technical field of material penetration testing, in particular to a diaper absorption performance testing device. Background Art

[0002] The diaper water absorption test simulates the penetration and absorption process of urine to measure the water absorption capacity and water retention capacity of diapers. This test method is designed to scientifically and accurately reflect the performance of diapers in actual use, ensuring that they can absorb urine quickly and effectively, reduce direct contact of urine with the skin, and thus reduce the incidence of skin problems such as diaper rash. The process of testing the absorption performance of diapers requires the use of corresponding testing equipment.

[0003] In the prior art, the detection device for the absorption performance of diapers directly clamps and fixes the diaper to be tested, then injects clean water from the top, calculates the difference between the injection amount and the final overflow amount, and obtains the final absorption amount. The absorption amount is used to reflect the absorption performance of the diaper to be tested. However, once the diaper is kept in a flat position in actual application, it will be squeezed, and the conventional detection device cannot accurately simulate the current water absorption performance after being squeezed in different directions during use. Therefore, the test environment cannot be fully simulated. On the other hand, it is also difficult for conventional detection devices to directly measure the penetration performance of the diaper to be tested during the absorption process, and the penetration performance of the water injection point in different directions will be different due to the influence of gravity factors and the shape of the diaper to be tested itself. This makes it more difficult for conventional detection devices to comprehensively measure the parameters of penetration in different directions of different water injection points. Summary of the invention

DETAILED DESCRIPTION

[0026] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0027] See also Figures 1 to 6The present invention provides the following technical solutions: a diaper absorption performance detection device, comprising a detection device body, the detection device body comprising a bracket 2, a water injection tank 3, a clamping assembly 5 and a test assembly 6, a bottom plate 1 is welded to the bottom of the bracket 2, a slide groove 9 is provided on the surface of the bottom plate 1, and the slide groove 9 is annular in structure as a whole, the side of the water injection tank 3 is welded to the top position of the bracket 2, and the water injection tank 3 is a columnar structure as a whole, a connecting pipe 25 is inserted at the bottom of the water injection tank 3, and the test assembly 6 is installed at the end of the connecting pipe 25, a bottom slip ring 12 is welded to the bottom of the clamping assembly 5, and the bottom slip ring 12 is embedded in the inside of the slide groove 9 as a whole, and a top slip ring 20 is welded to the top of the clamping assembly 5, and the top slip ring 20 is sleeved on the surface of the water injection tank 3, and the central axes of the water injection tank 3, the top slip ring 20 and the bottom slip ring 12 coincide with each other, and the bottom of the water injection tank 3 is used to open the diaper to be tested from the inside. The diaper absorption performance testing device is used to test the water absorption and multi-directional permeability of the diaper to be tested.

[0028] When the present invention is used, the clamping assembly 5 is first released from the clamping state, and then the diaper to be tested is placed on the bottom position of the water injection tank 3 from the bottom to ensure that the wearing opening of the diaper to be tested is in contact with the side bottom of the water injection tank 3, and then the diaper to be tested can be squeezed from the outside by the clamping assembly 5 with the help of the first clamping plate 17 and the second clamping plate 18, and the diaper to be tested can be clamped and fixed with the water injection tank 3 on the inside. In this process, the entire clamping assembly 5 can be controlled to rotate in advance, and the lifting plate 22 can be controlled to descend, so that the lifting plate 22 and the outer second clamping plate 18 can squeeze one side of the diaper to be tested, so as to simulate the water absorption performance of the diaper when one side is squeezed due to lying down in a normal use state. After the installation is completed, a certain amount of clean water can be injected into the water injection channel 7, and the inside of the diaper to be tested can be sprayed with water by means of the test component 6 at the bottom until it is completely injected. The clean water that is not completely absorbed drips and is collected in the measuring tube 4 at the bottom. The amount of water absorbed by the diaper to be tested can be calculated through the measuring tube 4, so as to obtain the water absorption performance data. At the same time, in conjunction with the humidity detection module 33 in the test component 6, the amount of water that the clean water penetrates in any direction along the diaper to be tested during the water spraying process can also be tested, so as to obtain the permeability data. The humidity detection module 33 is an existing mature technology and does not belong to the protection scope of the present invention. In this embodiment, a conventional humidity detection sensor on the market can be used to achieve the functions required by this embodiment, so its specific principle and structure are not described in detail here.

[0029] In this embodiment, a water injection channel 7 is provided inside the water injection box 3, a water injection port 8 is provided on the top of the water injection box 3, a card slot 11 is provided on the side of the water injection box 3, and the card slot 11 is annular in structure as a whole, a measuring tube 4 is inserted in the middle position of the surface of the bottom plate 1, a funnel 10 is integrally formed on the top of the measuring tube 4, and scale lines are engraved on the side of the measuring tube 4, the measuring tube 4 is inserted as a whole at the center point of the slide groove 9, the water injection channel 7 is partially connected with the water injection port 8 on the top, the bottom of the water injection channel 7 is connected with the inside of the connecting pipe 25, the bottom of the measuring tube 4 is connected with a drainage pipe, and a valve is installed on the drainage pipe at the bottom of the measuring tube 4. Specifically, the slide groove 9 on the bottom plate 1 provides support and rotation guidance for the entire clamping assembly 5, ensuring that the positions of the second clamping plate 18 and the lifting plate 22 relative to the diaper to be tested can be changed, so that the diaper to be tested can be clamped from any position. At the same time, during subsequent tests, a certain amount of clean water will be injected into the water injection channel 7 through the water injection port 8 at the top, and a certain amount of clean water will be sprayed onto the inner side of the diaper to be tested through the connecting pipe 25 at the bottom.

[0030] In this embodiment, the clamping assembly 5 includes a column 13, a first clamping plate 17 and a second clamping plate 18. A threaded sleeve 14 is provided on the surface of the column 13. A screw 15 is inserted into the interior of the threaded sleeve 14. A hand wheel 16 is installed at one end of the screw 15. The other end of the screw 15 is movably connected to the first clamping plate 17 or the second clamping plate 18 through a sleeve bearing. An extension rod 19 is welded to one side of the top of the column 13. The end of the extension rod 19 is welded to the top sliding The surface of the ring 20, the inner side of the top slip ring 20 is integrally formed with a snap ring 21, the bottom of the column 13 is welded to the surface of the bottom slip ring 12, the snap ring 21 is integrally embedded in the inside of the card slot 11, and the inner side of the top slip ring 20 is inserted with a lifting plate 22, the surface of the lifting plate 22 is aligned with the second clamping plate 18, and the lifting plate 22, the first clamping plate 17 and the second clamping plate 18 are all in an arc structure, and the bottom of the first clamping plate 17 is flush with the bottom of the water injection tank 3. By setting the diaper to be tested at the bottom of the water injection tank 3 and clamping and fixing the edge of the diaper to be tested by the clamping assembly 5, this process can provide an additional squeezing effect at any position on the side of the diaper to be tested with the help of the clamping assembly 5, so that the water absorption performance of the diaper to be tested after being squeezed in different postures can be directly simulated, and the test results are more accurate.

[0031] Specifically, during installation, the diaper to be tested is first placed on the bottom of the water injection tank 3. If there is no need to simulate the situation that one side of the diaper to be tested is squeezed, there is no need to rotate the slip ring and lift the lifting plate 22. The two hand wheels 16 can be directly rotated to control the first clamping plate 17 and the second clamping plate 18 to press the diaper to be tested against the side of the water injection tank 3. If it is necessary to simulate the situation that one side of the diaper to be tested is squeezed, first rotate the bottom slip ring 12 and pull down the lifting plate 22 until the lifting plate 22 is rotated to align with the set squeezing position on the diaper to be tested, and then use the first clamping plate 17 and the second clamping plate 18 to squeeze the diaper to be tested. At this time, one side of the diaper to be tested can be pressed by the second clamping plate 18 and the lowered lifting plate 22. The diaper to be tested will be compressed after being pressed, thereby interfering with the water absorption and permeability during subsequent water absorption tests.

[0032] In this embodiment, the test assembly 6 includes a first adjusting disk 27, a second adjusting disk 28 and a water filling disk 26. A lower hanging plate 23 is welded to the bottom of the water filling box 3, and a locking bolt 24 is inserted into the end of the lower hanging plate 23. The water filling disk 26 is welded to the end of the connecting pipe 25. A sealing sleeve 34 and a sealing ring 35 are installed on the surface of the water filling disk 26. The rear end of the first adjusting disk 27 is sleeved on the surface of the sealing sleeve 34, and the surface of the first adjusting disk 27 is partially fitted with the sealing ring 35. The side of the first adjusting disk 27 is connected to a water spray pipe 29. A telescopic sleeve 30 is welded to the side of the second adjustment disk 28, and an insertion rod 32 is inserted into the inside of the telescopic sleeve 30. A humidity detection module 33 is embedded on the surface of the insertion rod 32. A push block 31 is installed on the surface of the insertion rod 32, and the push block 31 passes outward from the top of the telescopic sleeve 30. A central groove 37 is opened on the surface of the second adjustment disk 28. The middle of the first adjustment disk 27 is embedded into the inside of the second adjustment disk 28 through a docking bearing 36, and the inner side of the lower hanging plate 23 is embedded into the inside of the central groove 37 through a bearing. At the bottom, the inner side of the diaper to be tested is tested by the test component 6, and the test component 6 can control the water spray pipe 29 and the humidity detection module 33 to align and contact with multiple points of the diaper to be tested through multiple rotating structures, so that the parameters of penetration from different water injection points to different directions can be directly measured in all aspects, so that more comprehensive water absorption data can be obtained.

[0033] Before testing the water absorption and permeability through the test component 6 at the bottom, the directional position of the water spraying point and the point to be penetrated can be directly controlled manually, and after the adjustment is completed, a locking effect is provided with the help of the locking bolt 24. At the same time, through its own structural design, the water filling plate 26 part that provides a rotating connection is also subject to the squeezing effect, which further ensures that no leakage will occur during subsequent testing and improves the reliability of the data.

[0034] Specifically, when conducting the test, first rotate the first adjustment disk 27 and the second adjustment disk 28 to change the directional positions of the water spray pipe 29 and the telescopic sleeve, then pull the push block 31 to embed the end of the insertion rod 32 into the inner side of the diaper to be tested, and simultaneously embed the humidity detection module 33 into the interior of the diaper to be tested. At this time, the locking bolt 24 can be rotated, and the end of the locking bolt 24 can be pressed against the front end of the second adjustment disk 28, and a backward thrust can be applied, so that the first adjustment disk 27 and the second adjustment disk 28 can be used to press on the sealing ring 35 to ensure that subsequent clean water can have a higher sealing when entering the first adjustment disk 27. During subsequent testing, clean water is sprayed from the water spray pipe 29 into the inner side of the diaper to be tested, and during the process of penetration and diffusion, the humidity detection module 33 detects the time required for penetration from the water spray pipe 29 to the humidity detection module 33, thereby judging the permeability performance of the diaper to be tested.

For those skilled in the art, it is obvious that the present invention is not limited to the details of the above exemplary embodiments, and the present invention can be implemented in other specific forms without departing from the spirit or basic characteristics of the present invention.
