Description

Technical Field

[0001] This invention relates to the field of in-vehicle textile testing technology, specifically to a quality testing device for in-vehicle textiles. Background Technology

[0002] For in-car textiles, especially ceiling fabrics, seat fabrics, and carpets, the ability to resist water penetration is particularly important. When drinking water in the car, it is very easy to spill it onto the textiles. The textiles absorb the liquid due to their own properties. However, if the absorbed liquid penetrates to the deepest parts of the textiles, it will be difficult for the liquid to evaporate naturally, resulting in a fermented smell in the car and affecting the air quality. Therefore, testing of in-car textiles is particularly important.

[0003] For example, in the patent document with application number 202323628381.1, a precise penetration detection device for textiles is disclosed, specifically disclosing that water is sprayed onto textile samples through a rain spray component to detect the textiles.

[0004] In the above technical solution, the penetration of textiles inside the vehicle cannot be simulated when testing them. Furthermore, the amount of rain sprayed by the rain shower component is relatively large, and weighing is insufficient to detect small amounts of liquid penetration, thus affecting the accuracy of the test. Summary of the Invention

[0005] The purpose of this invention is to provide a quality inspection device for in-vehicle textiles.

[0006] The technical problem solved by this invention is to address the issue that existing technologies cannot simulate the permeation process when testing textiles inside vehicles.

[0007] The present invention can be achieved through the following technical solution: a quality inspection device for in-vehicle textiles, including a movable plate that can move, a support mechanism for supporting a first test sample on the movable plate, a test slot on the movable plate, a top test plate above the test slot, and the top test plate fixed on a top base.

[0008] A further technical improvement of the present invention is that the support mechanism includes a test take-up roller and a waste take-up roller, a first base and a second base are provided on both sides of the movable plate, a test take-up roller for taking up and supporting the first test sample is rotatably provided on the first base, and a waste take-up roller for supporting the test sample is provided on the side of the second base.

[0009] A further technical improvement of the present invention is that: a test roller is rotatably arranged on the second base, and a support roller is rotatably arranged on the side of the second test base, and the support roller and the waste winding roller are at the same height.

[0010] A further technical improvement of the present invention is that: the test roller is rotatably mounted on the rotating rod, the rotating rod is mounted on the rotating base through a torsion spring, and the rotating base is fixedly mounted on the second base.

[0011] A further technical improvement of the present invention is that: the test roller is rotatably mounted on the first rod, the first rod is rotatably connected to the second rod via a torsion spring, and the second rod is rotatably mounted on the second base.

[0012] A further technical improvement of the present invention is that: a bottom moving component is fixedly installed on the top base through a supporting base, a bottom base is provided at the output end of the bottom moving component, a bottom rotating wheel is rotatably provided on the bottom base, and several sets of test nozzles are evenly arranged on the bottom rotating wheel.

[0013] A further technical improvement of the present invention is that a side support plate is fixed to the side of the movable plate, and a spectral scanner for scanning and detecting the top test plate is provided on the side support plate.

[0014] A further technical improvement of the present invention is that a side support column is fixed on the bottom base, and a side humidity detection sensor for detecting the test sample is provided on the side support column.

[0015] A further technical improvement of the present invention is that: the bottom moving component includes a moving base, a limiting groove is formed on the moving base, a moving roller is arranged inside the limiting groove, a moving conveyor belt is arranged on the adjacent moving roller, a limiting slider is fixed on the moving conveyor belt, the limiting slider and the limiting groove are slidably connected, and the limiting slider and the bottom base are fixedly connected.

[0016] Compared with the prior art, the present invention has the following beneficial effects: 1. This application utilizes a movable and rotatable precision nozzle assembly to simulate a real-world scenario where liquids such as water or beverages are spilled onto textiles in a small, targeted manner under controlled pressure inside a vehicle, rather than the traditional method of large-area rain. This makes the testing conditions more consistent with actual accidental spills. Furthermore, this application mixes a fluorescent agent into the test liquid, and after penetration, uses a spectral scanner to image and analyze the test plate below. This method can visualize and accurately quantify the area, distribution, and amount of liquid penetration, far exceeding the accuracy of traditional methods relying on weighing or visual observation. It can effectively distinguish between the surface impermeability and deep absorption performance of fabrics.

[0017] 2. The device of this application integrates real-time penetration detection (spectral scanning) and residual humidity detection (side humidity sensor). It can not only determine whether the liquid has penetrated, but also assess the internal residual humidity of the textile after absorbing the liquid, thereby predicting its drying speed and the risk of odor generation. In addition, the test roller of this application adopts a spring or torsion spring hinge structure, which can automatically adjust when the liquid is sprayed and impacted, keeping the test fabric in a flat and taut stable state, avoiding the influence of fabric looseness or wrinkles on the penetration path, and ensuring the reliability and repeatability of the test results.

[0021] To further illustrate the technical means and effects adopted by the present invention in order to achieve the intended purpose, the following detailed description is provided in conjunction with the accompanying drawings and preferred embodiments, based on the specific implementation methods, structures, features and effects of the present invention.

[0022] Please see Figures 1-6 As shown, the quality inspection device for in-vehicle textiles includes a top base 1, wherein a support base 5 is fixed to the side of the top base 1, and the support base 5 and the bottom moving component 6 are fixedly connected. The bottom moving component 6, the support base 5 and the top base 1 form a stable frame, thereby enabling stable inspection of textiles.

[0023] The bottom moving component 6 includes a moving base 31, on which a limiting groove 35 is formed. A moving roller 30 is connected to the inside of the limiting groove 35 via a moving motor. A moving conveyor belt 34 is sleeved on an adjacent moving roller 30. A limiting slider 32 is fixed on the moving conveyor belt 34, and the limiting slider 32 is slidably connected to the limiting groove 35. A moving mounting base 33 is fixed on the limiting slider 32, and a detection mechanism for inspecting textiles is provided on the moving mounting base 33. In this application, the moving roller 30 is driven by a moving motor, which in turn causes the moving conveyor belt 34 to move the limiting slider 32, allowing the limiting slider 32 to slide within the limiting groove 35, adjusting the position of the detection mechanism for convenient inspection of textiles.

[0024] Furthermore, the testing mechanism includes a bottom base 7, which is fixedly mounted on a movable mounting base 33. A bottom support rod 8 is fixedly mounted on the bottom base 7, and a bottom wheel 9 is rotatably mounted on the bottom support rod 8 via a rotating motor. Several test nozzles 10 are evenly arranged on the bottom wheel 9. Each test nozzle 10 is connected to a different fluorescent agent mixing tank via a suction pump. The fluorescent agent mixing tank contains a liquid of the required viscosity, and the fluorescent agent is mixed into the liquid to facilitate the capture of test results. Therefore, during use, the movement of the movable mounting base 33 controls the movement of the bottom wheel 9, and the rotation of the bottom wheel 9 is controlled by the rotating motor, thereby controlling the accuracy of the spray area 11 acted upon by the test nozzles 10. Due to the use of different types of fluorescent agents, the penetration results during the test can be judged, thus obtaining more accurate test results. The rotation of the bottom wheel 9 can also adjust the spraying of liquids of different viscosities, ensuring the completeness of the textile penetration test and further ensuring the accuracy of the results.

[0025] Furthermore, a top moving component 41 is provided on the top base 1, and a top test plate 14 is provided on the top of the top base 1. A clamping mechanism 12 for clamping the textile is provided at the output end of the top moving component 41. Therefore, in use, the top moving component 41 drives the clamping mechanism 12 to move, thereby moving the textile so that the textile can cooperate with the test nozzle 10 for testing. The liquid sprayed after penetration will adhere to the top test plate 14, which is convenient for capturing the results, thereby obtaining more accurate results.

[0026] Furthermore, the top moving assembly 41 adopts a lead screw assembly set on the side of the top base 1. That is, a lead screw is rotatably set on the side of the top base 1, driven by a motor, and drives a slider threaded on the lead screw to slide. The slider is slidably connected to the top base 1, thereby driving the clamping mechanism 12 fixedly installed on the slider to move, so that the clamping mechanism 12 can move the textile, ensuring sufficient testing of the textile. At the same time, the lead screw is set on the side of the top base 1, so that the textile can act on the top test plate 14 during testing, achieving sufficient testing of the textile.

[0027] Furthermore, the clamping mechanism 12 includes a movable plate 18, which is fixedly mounted on a slider. The slider drives the movable plate 18 to move. A test groove 19 is provided on the movable plate 18, which allows liquid to pass through and act on the top test plate 14, thereby achieving preliminary detection of the first test sample 20. A first base 15 is fixed at the bottom of the movable plate 18, and a test take-up roller 26 is rotatably mounted on the first base 15 via a take-up motor. The first test sample 20 rotates on the test take-up roller 26. A second base is fixed on the side of the movable plate 18 away from the first base 15. The second base 22 has a test roller 21 for tension testing of the first test sample 20. A support roller 23 is provided on the side of the test roller 21, and a waste take-up roller 24 is provided on the side of the support roller 23 via a take-up motor. The bottom heights of the waste take-up roller 24 and the support roller 23 are the same. At this time, the first test sample 20 has been tested to obtain a test inspection sample 25. The test inspection sample 25 is tested. When the first test sample 20 is located between the test take-up roller 26 and the test roller 21, the test nozzle 10 is used to test the first test sample 20, thereby obtaining a more accurate test result.

[0028] As a further embodiment of this application, a side support plate 16 is fixed on the movable plate 18, wherein a spectral scanner 17 is fixed on the side support plate 16. The spectral scanner 17 acts on the top test plate 14 to capture the fluorescent agent that permeates on the top test plate 14, determine the area of ​​fluorescent agent distribution, thereby determining the transmittance of the fluorescent agent, and further determining the permeability of the liquid.

[0029] Furthermore, a side support column 3 is fixed on the bottom base 7, and a side humidity detection sensor 2 is fixed on the side support column 3. The side humidity detection sensor 2 acts on the test sample 25 to test the absorption of the test sample 25 and determine its humidity, thereby enabling a thorough test of the textile.

[0030] Furthermore, the test roller 21 is rotatably mounted on the rotating rod 36, which is rotatably mounted on the rotating base 37 via a torsion spring. The rotating base 37 is fixedly mounted on the second base 22. During use, when liquid is sprayed onto the first test sample 20, the test roller 21 bears a certain upward force, causing the rotating rod 36 to deflect to a certain extent, thereby tensioning the first test sample 20 and further ensuring the accuracy of its test.

[0031] As a further embodiment of this application, the test roller 21 is rotatably mounted on the first rod 38, the first rod 38 is rotatably mounted on the hinge shaft 39 via a torsion spring, and the second rod 40 is rotatably mounted on the hinge shaft 39 via another torsion spring. The second rod 40 is rotatably mounted on the second base 22 via a torsion spring. In use, when liquid is sprayed onto the first test sample 20, the test roller 21 bears a certain upward force, causing the first rod 38 and the second rod 40 to rotate to a certain extent, further tensioning the first test sample 20 and further ensuring the accuracy of its test.

[0032] Furthermore, the top test plate 14 is provided with a spare surface 28 and a test surface 29, which are respectively set on the conveyor belt and driven by the flip roller 27. The flip roller 27 drives the conveyor belt to rotate, so that the test surface 29 moves to the position of the spare surface 28, and the test surface 29 is cleaned to achieve non-stop testing.

[0033] In use, the present invention first places the test take-up roller 26, on which the first test sample 20 is wound, on the first base 15. Then, the first test sample 20 is wound onto the waste take-up roller 24 after passing through the test roller 21 and the support roller 23. Subsequently, the top moving component 41 drives the clamping mechanism 12 to move. At this time, the bottom moving component 6 drives the bottom base 7 to move, and the rotation of the bottom rotating wheel 9 controls the spraying area 11, spraying the liquid carrying the fluorescent agent onto the first test sample 20. The force of the spray determines whether the liquid carrying the fluorescent agent is sprayed onto the first test sample 20. After the fluorescent agent liquid passes through the test tank 19, it comes into contact with the top test plate 14. As the clamping mechanism 12 moves, the spectral scanner 17 acts on the top test plate 14 to capture the fluorescent agent on the top test plate 14, thereby initially determining the permeability of the first test sample 20. Then, by rotating the test take-up roller 26 and the waste take-up roller 24, the first test sample 20 is moved to the position of the test inspection sample 25. The humidity of the test inspection sample 25 is detected by the side humidity detection sensor 2, further realizing the testing function of textiles. In the above technical solution, each test nozzle 10 is connected to a different fluorescent agent mixing tank via a suction pump. The fluorescent agent mixing tank contains a liquid of the required viscosity, and the fluorescent agent is mixed into the liquid to facilitate the capture of test results. Therefore, during use, the movement of the bottom wheel 9 is controlled by the movement of the movable mounting base 33. During use, the rotation of the bottom wheel 9 is controlled by a rotating motor, thereby controlling the accuracy of the spray area 11 acted upon by the test nozzle 10. Furthermore, due to the use of different types of fluorescent agents, the penetration results during the test can be judged, thus obtaining more accurate test results. The rotation of the bottom wheel 9 can also adjust the spraying of liquids of different viscosities, ensuring the completeness of the textile penetration test and further ensuring the accuracy of the results.
