Technical Field

[0001] This invention relates to the field of textile testing equipment technology, and in particular to a device and method for chemical testing of the surface of textile consumer products. Background Technology

[0002] Textile production involves the use of numerous chemicals, which may remain on the final product and pose health risks through skin contact or inhalation. Certain azo dyes, upon prolonged contact with the human body, can decompose to produce carcinogenic aromatic amines, potentially inducing cancer. Formaldehyde is a common allergen, causing skin itching, redness, and even asthma. Excessively high pH levels can damage the skin's slightly acidic protective layer, leading to dryness, itching, or allergies. Heavy metal residues can also accumulate toxicity through skin contact. Some alkylphenol polyoxyethylene ethers and phthalates are considered endocrine disruptors that may interfere with the human endocrine system, affecting reproduction and development. Therefore, surface chemicals in textiles need to be tested. The most common testing equipment currently available is a water fastness tester. However, existing water fastness testers have some problems and defects that can affect their usability.

Therefore, the terms used to describe positional relationships in the drawings are only for illustrative purposes and should not be construed as limiting the present patent. For those skilled in the art, the specific meaning of the above terms can be understood according to the specific circumstances.

[0024] The technical solution of the present invention will be further described in detail below through specific embodiments and in conjunction with the accompanying drawings: Example 1: like Figure 1-6 As shown, this embodiment provides a chemical detection device for the surface of textile consumer products, including a frame 1; An adjustment component is mounted on the frame 1 and is used to adjust the position of the textile. A clamping assembly, two sets of the clamping assemblies are mounted on the movable end of the adjusting assembly, the clamping assemblies being used to cooperate with the adjusting assembly to clamp and flatten the textile fabric; A friction assembly, mounted on the clamping assembly, for rubbing a textile fabric; A cleaning assembly, which is mounted on the frame 1, is used for washing textiles. A detection component is mounted on the frame 1 and is equipped with a detection part for visually identifying and analyzing the color fastness of textiles.

[0025] In this embodiment, the frame 1 has a U-shaped structure and a slot for textiles to pass through, with the slot facing downwards. Through holes 22 are provided on both sides of the frame 1. The cleaning component and the detection component are respectively located on both sides of the frame 1 through the through holes 22. A handle 8 is provided on the top of the frame 1.

[0026] In this embodiment, the frame 1 is also provided with detachable protective covers 73 on both sides. The protective covers 73 are used to protect the core components such as the detection components and cleaning components installed on both sides of the frame 1 from external dust, water stains and foreign objects, maintain the cleanliness and working stability of the internal components, and ensure that the detection process is not affected by environmental impurities and thus the accuracy of the results. At the same time, the detachable structural design makes it easy for operators to regularly inspect, calibrate or replace vulnerable parts of the internal components, improving the maintenance convenience of the device.

[0027] Specifically, the adjustment assembly includes a mounting frame 31, a mounting plate 32, a positioning gear 33, a positioning rack 34, a first motor 35, and positioning blocks 37. The bottom end of the mounting plate 32 is connected to the top end of the frame 1, and the bottom end of the mounting frame 31 is connected to the top end of the mounting plate 32. The first motor 35 is mounted on the mounting frame 31, and the output end of the first motor 35 passes through a machine hole 312 on the mounting frame 31 and is connected to the positioning gear 33. A pair of positioning blocks 37 are respectively mounted at both ends of the mounting frame 31. A pair of positioning racks 34 are slidably connected through positioning grooves 313 provided on each positioning block 37. The pair of positioning racks 34 mesh with both sides of the positioning gear 33 and slide away from or slide closer to each other. The ends of the positioning racks 34 away from the positioning gear 33 are rotatably connected to two adjusting arms 311. The clamping assembly is connected to the ends of the adjusting arms 311. The adjustment assembly also includes a driving component for driving the adjusting arms 311 to change the clamping distance.

[0028] In this embodiment, a limiting rod 36 is provided on one side of each of the two positioning racks 34, and a limiting hole 314 is provided on each of the two racks 34 to cooperate with the limiting rod 36. The limiting rod 36 of each positioning rack 34 is inserted into the limiting hole 314 of its corresponding positioning rack 34 to limit the offset of the positioning rack 34 during the sliding process, ensuring that it always moves smoothly along the extension direction of the positioning groove 313, avoiding the failure of meshing with the positioning gear 33 due to rack misalignment, thereby ensuring the fitting accuracy of the adjustment component to the width of the textile and improving the stability of the clamping component in flattening the textile.

[0029] Specifically, the driving component includes a first electric push rod 38, a connecting rod 39, and a connecting block 310. The first electric push rod 38 is fixedly connected to the positioning rack 34, and the connecting block 310 is connected to the output end of the first electric push rod 38. One end of the connecting rod 39 is rotatably connected to the connecting block 310, and the other end of the connecting rod 39 is rotatably connected to the mounting groove 315 of the adjusting arm 311.

[0030] Specifically, the clamping assembly includes a support shaft 41 and a pressing roller 43. The adjusting arm 311 is provided with a shaft hole 21. The support shaft 41 passes through the shaft hole 21 and is fixedly fitted with the adjusting arm 311. The pressing roller 43 is rotatably connected to the support shaft 41 through a first connecting piece 42 with a coil spring 49.

[0031] In this embodiment, a total of four adjusting arms 311 are provided, with two adjusting arms 311 forming a group. The two adjusting arms 311 drive the corresponding support shaft 41 and the pressing roller 43 mounted on the support shaft 41 to move synchronously to achieve clamping. The two groups of adjusting arms 311 can drive each pressing roller 43 to symmetrically clamp the textile from both sides of the edge. Under the elastic force of the coil spring 49, the pressing roller 43 is tightly attached to the surface of the textile, which not only ensures sufficient clamping force to flatten the fabric, but also avoids fabric deformation or damage caused by excessive compression through the buffering effect of the coil spring 49.

[0032] Specifically, the friction mechanism includes a second connecting plate 47, a bending frame 48, a second motor 44, a drive gear 45, a driven gear 46, a third motor 411, and a friction wheel 412. The second connecting plate 47 is rotatably connected to the support shaft 41 through a through hole 410. The top end of the bending frame 48 is connected to the bottom end of the second connecting plate 47. The second motor 44 is mounted on the bending frame 48, and the output end of the second motor 44 is connected to the drive gear 45. The driven gear 46 is fixedly connected to the bottom end of the support shaft 41 and meshes with the drive gear 45. The third motor 411 is mounted on the second connecting plate 47, and the output end of the third motor 411 is connected to the friction wheel 412.

[0033] In this embodiment, the friction assembly moves synchronously with the support shaft 41 to the friction test area of ​​the textile. The second motor 44 drives the drive gear 45 to rotate, and drives the second connecting piece 47 to rotate around the driven gear 46 and the support shaft 41 as the rotation axis, thereby adjusting the contact angle between the friction wheel 412 and the surface of the textile, ensuring that the friction wheel can adhere to the fabric with a preset pressure and angle, providing stable contact conditions for the subsequent rubbing color fastness test. After the third motor 411 is started, the friction wheel 412 rotates and performs reciprocating friction on the surface of the textile, simulating the wear scenario in daily use, so that the detection assembly can accurately capture the color change and chemical residue on the surface of the fabric.

[0034] Specifically, it also includes a flipping mechanism, which includes a side plate 51, a flip plate 52, and a flipping drive component. The side plate 51 is fixedly installed in the through hole 22 of the frame 1. The flip plate 52 is rotatably connected to the lateral groove 57 provided on the side plate 51. The flipping drive component includes a second electric push rod 56, a rolling rack 54, and a rolling gear 53. The rolling gear 53 is fixed at the bottom end of the flip plate 52. The rolling rack 54 is slidably connected to the slide rail 55 provided on the side plate 51 and meshes with the rolling gear 53. The second electric push rod 56 is connected to the side plate 51. The output end of the second electric push rod 56 is connected to the rolling rack 54 to drive the rolling rack 54 to slide along the slide rail 55. The cleaning assembly is installed on the flip plate 52.

[0035] In this embodiment, a guide groove 58 is provided on one side of the rolling rack 54, and the rolling rack 54 is slidably connected to the slide rail 55 through the guide groove 58.

[0036] In this embodiment, after the textile completes the friction test, the second electric push rod 56 pushes the rolling rack 54 to slide along the slide rail 55, causing the rolling gear 53 meshing with it to rotate, thereby driving the flip plate 52 to flip in the side groove 57 to a preset angle, so that the cleaning component installed on the flip plate 52 is precisely aligned with the water washing test area of ​​the textile. At this time, the atomizer 61 in the cleaning component connects to the water supply passage of the water bottle 62, and sprays the atomized water film evenly onto the surface of the textile. At the same time, the brush 63 rotates at high speed under the drive of its built-in micro drive motor (not shown), and performs a gentle brushing of the textile surface to simulate daily water washing, effectively removing the fiber debris and surface attachments left by friction.

[0037] Specifically, the cleaning assembly includes an atomizer 61, a water bottle 62, and a brush 63. The atomizer 61 and the brush 63 are installed on one side of the flap 52, and the water bottle 62 is installed on the other side of the flap 52. The water bottle 62 is connected to the input end of the atomizer 61.

[0038] In this embodiment, the flap 52 is provided with a connection hole 64, and the atomizer 61 passes through the connection hole 64 and is fixedly fitted to the flap 52.

[0039] Specifically, the detection component includes a vision sensor 76, a main control box 74, and a signal processor 75. The main control box 74 is electrically connected to the signal processor 75 and the vision sensor 76, respectively. The vision sensor 76 is positioned facing the clamping station of the clamping component.

[0040] In this embodiment, a fixing plate 72 is provided on the through hole 22 on the side of the frame 1 away from the cleaning component, and the vision sensor 76, the main control box 74 and the signal processor 75 are respectively installed on the fixing plate 72.

[0041] In this embodiment, the central control box 74, as the core control unit of the device, integrates a PLC control system and a touch operation interface. It can receive feedback signals from actuators such as the first motor 35, second motor 44, third motor 411, first electric push rod 38, second electric push rod 56, and atomizer 61 in real time. It automatically sends start / stop, angle adjustment, and speed control commands according to a preset detection process, achieving automated and coordinated operation of the entire process of adjustment, clamping, friction, washing, and detection. Simultaneously, the central control box 74 also allows operators to manually set detection parameters, such as the number of friction cycles, washing time, and ultraviolet irradiation intensity, through the touch interface, and stores historical detection data for subsequent traceability and analysis. The signal processor 75 has a built-in high-performance image algorithm module that can quickly process the textile surface images captured by the vision sensor 76. During the color fastness test, it analyzes the color difference of the textile before and after friction or washing using the RGB color space, automatically determines the color fastness level according to standard specifications, and transmits the analysis results to the display interface of the central control box 74 in real time, presenting them to the operator in intuitive charts or numerical form. In addition, both the main control box 74 and the signal processor 75 adopt a modular design, which, together with the protective cover 73, ensures the electromagnetic compatibility and anti-interference capability of the internal circuits.

[0042] Example 2: This embodiment is similar to Embodiment 1, except that, in this embodiment, as Figure 2 , 6 As shown, it also includes an ultraviolet spotlight 71 electrically connected to the main control box 74. The ultraviolet spotlight 71 is arranged facing the clamping station of the clamping assembly. The ultraviolet spotlight 71 faces one side of the clamping station, and the vision sensor 76 faces the other side of the clamping station. The ultraviolet spotlight 71 can simulate the effect of sunlight exposure, and the color fastness to sunlight can be tested in conjunction with the vision sensor 76 and the signal processor 75.

[0043] In this embodiment, the ultraviolet spotlight 71 is mounted on the fixed plate 72, and the vision sensor 76 is mounted on the flip plate 52, on the same side as the water bottle 62. This prevents the water mist generated by the atomizer 61 from directly splashing onto the lens surface of the vision sensor 76, thus preventing water mist adhesion and lens blurring. This ensures that the vision sensor 76 can clearly capture the details of the fluorescence reaction or color change on the textile surface under ultraviolet irradiation, thereby guaranteeing the accuracy of the wash fastness test results. Simultaneously, the ultraviolet spotlight 71 and the vision sensor 76 are located on opposite sides of the clamping station, forming a facing detection layout. This allows the ultraviolet light to evenly cover the textile detection area, and the vision sensor 76 can receive reflected light signals from the optimal angle, further improving the reliability of the detection data. Furthermore, this layout design reduces spatial interference between the detection and cleaning components, making the internal structure of the device more compact and optimizing overall space utilization. During the detection stage, the grayscale value of the fluorescent area generated under the ultraviolet spotlight 71 is extracted and compared with a threshold to accurately identify the distribution range and concentration level of residual chemical substances.

[0044] In this embodiment, since the vision sensor is installed on the flip plate 52, after the washing is completed, the second electric push rod 56 pulls the rolling rack 54 to make the flip plate 52 flip so that the vision sensor 76 is aligned with the textile. The vision sensor 76 captures the color fading and staining of the textile in the washing area in real time.

[0045] Example 3: like Figure 7 As shown, this embodiment provides a method for chemical detection of the surface of textile consumer products, employing the aforementioned detection device and including the following steps: S1: The adjustment component is used to adapt to the size of the textile to be tested, and the clamping component is used to flatten and fix it. S2: Activate the friction mechanism on the clamping assembly to rub the textile, and cooperate with the detection assembly to test the color fastness of the rubbing area of ​​the textile. S3: Move the textile that has been rubbed to the cleaning station, start the cleaning assembly to clean its surface, and cooperate with the detection assembly to test the color fastness of the water-washed area of ​​the textile.

[0046] In this embodiment, a light fastness test is also included, the specific process of which is as follows: after the textile is flattened and fixed by the clamping component and the adjusting component, Although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention.
