Description

Technical Field

[0001] The present invention relates to the technical field of cloth printing and dyeing difference detection, and in particular to a cloth printing and dyeing difference detection device. Background Art

[0002] As the textile printing and dyeing industry continues to flourish, consumers are increasingly demanding textile quality. Color consistency, in particular, has become a key indicator of product quality. Poor printing and dyeing not only impacts the aesthetics of the product but also impacts a company's market reputation and profitability. Traditional methods for detecting poor printing and dyeing rely primarily on manual experience and simple instrumentation, which presents numerous drawbacks.

[0003] Manual inspection methods are highly subjective, and the judgment standards of different inspectors may differ, resulting in a lack of accuracy and consistency in the inspection results. Moreover, manual inspection is inefficient and cannot meet the needs of large-scale production. In addition, traditional inspection equipment shows obvious limitations when faced with complex fabric materials and printing and dyeing processes. For example, for woven fabrics made of cotton, linen or flax materials, wrinkles are easily generated due to their soft texture. After folding and long-term external force compression, wrinkles that are difficult to eliminate will remain on the surface of the fabric. During the inspection process, these wrinkles will prevent the detection end from fitting tightly against the fabric surface, forming gaps where the wrinkles overlap, seriously interfering with the detection equipment's accurate judgment of color difference, resulting in deviations in the detection results. To this end, we propose a fabric printing and dyeing difference detection device to solve the above problems. Summary of the Invention

[0013] Preferably, the detection unit includes an LED lighting fixture, a color difference detector and a detection sensor.

[0014] In the present invention, when color difference detection is performed:

[0015] 1. Fabric placement: The fabric to be tested is passed through the second opening on one side of the testing box, and then passes through the clamping device in one of the carrier boxes in turn. Then, the fabric is placed on the upper end of the support roller, and finally the other end of the fabric is passed through the clamping device in the other carrier box again to complete the initial placement of the fabric.

[0016] 2. Fabric flattening: Start the hydraulic pushing mechanism, which consists of fixed blocks fixed to both sides of the protective box, a rotatably connected folding frame, a mounting block, and a first hydraulic cylinder. The piston rod of the first hydraulic cylinder pushes the mounting block, driving the folding frame to unfold, so that the mounting plates on both sides slide on the bottom of the protective box through the slider, and then drives the supporting boxes and clamping devices on both sides to move to the sides, realizing the expansion of the fabric.

[0020] The present invention has the following advantages:

[0021] 1. The hydraulic pushing mechanism and clamping device are used to flatten the fabric, and the lifting limit mechanism is used to provide auxiliary support for the fabric, effectively solving the problem of fabric wrinkles. This allows the detection end to be closely attached to the fabric surface, avoiding the influence of gaps caused by overlapping wrinkles on the detection results, and greatly improving the accuracy of color difference detection.

[0036] The detection equipment includes a fixed plate 1 fixed to one side of the top of the detection box 2, and a detection unit 29 is installed on the fixed plate 1. The hydraulic pushing mechanism includes two fixed blocks 12 fixed on both sides of the protection box 7. One side of the fixed block 12 is rotatably connected to the folding frame 10, and one end of the folding frame 10 is rotatably connected to the mounting block 30.

A first hydraulic cylinder 9 is installed on one side of the fixed block 12, and the end of the piston rod of the first hydraulic cylinder 9 is connected to one side of a mounting block 30 on the same side. The first hydraulic cylinder 9 adopts a high-precision hydraulic control system, which can accurately control the telescopic length and speed of the piston rod to ensure the stability and accuracy of the movement of the mounting plate 5. The folding frame 10 is made of high-strength metal and has undergone special surface treatment.

[0039] The lifting mechanism includes support columns 20 fixed on both sides of the upper end of the U-shaped mounting frame 26. The upper ends of the two support columns 20 are fixed with a bearing block 18 by screws 27. The upper end of the bearing block 18 is installed with a third hydraulic cylinder 16. The piston rod of the third hydraulic cylinder 16 passes through the bearing block 18 and is connected to the upper end of the first moving block 21. The upper end of the first moving block 21 is connected to two first springs 19. The upper ends of the two first springs 19 are connected to the lower end of the bearing block 18. The third hydraulic cylinder 16 can accurately control the lifting height of the first moving block 21. The first spring 19 plays a role of buffering and auxiliary reset, ensuring that the first clamping roller 25 is stable and reliable during the lifting process.

[0040] Two covers 17 are hinged on one side of the test box 2. The covers 17 are made of high-strength plastic with a smooth surface. They can not only effectively prevent external dust from entering the test box 2, but also operate smoothly when opened and closed, making it convenient for operators to maintain and clean the interior of the test box.

[0041] The four corners of the lower end of the detection box 2 are fixed with fixing parts 31, and the fixing parts 31 are rotatably connected to the rollers 15. The rollers 15 are equipped with brake devices, which can roll freely when the device needs to be moved; when the designated position is reached, the rollers are locked by the brake device to ensure that the device remains stable during the detection process;

[0042] The detection unit 29 includes an LED lighting fixture, a color difference detector and a detection sensor. The LED lighting fixture uses a light source with high color rendering index and can simulate different lighting environments, such as natural light, indoor light, etc., to meet the needs of different detection scenarios; the color difference detector has high-precision color recognition capabilities and can accurately detect subtle differences in fabric color. Its detection accuracy can reach ±0.1ΔE; the detection sensor can monitor the tension and flatness of the fabric and the temperature, humidity and other environmental parameters in real time to ensure the accuracy of the detection results.

[0043] In the present invention, when color difference detection is performed:

[0044] 1. Fabric placement: The fabric to be tested is passed through the second opening 14 on one side of the testing box 2, and then passed through the clamping device in one of the carrier boxes 3. Then, the fabric is placed on the upper end of the support roller 6. Finally, the other end of the fabric is passed through the clamping device in the other carrier box 3 again to complete the initial placement of the fabric. During the fabric placement process, the operator can use auxiliary tools, such as fabric guide rods, to ensure that the fabric can pass through each component accurately and avoid wrinkles or deviations. At the same time, the operator also needs to check the surface of the fabric for stains, damage, etc., and promptly deal with any problems if necessary.

[0045] 2. Fabric Flattening: The hydraulic push mechanism is activated. This mechanism consists of fixed blocks 12 fixed to both sides of the protective box 7, a rotatably connected folding frame 10, a mounting block 30, and a first hydraulic cylinder 9. The piston rod of the first hydraulic cylinder 9 pushes the mounting block 30, causing the folding frame 10 to expand. This causes the mounting plates 5 on both sides to slide along the bottom of the protective box 7 via sliders 11, which in turn drives the carrier box 3 and the clamping device on both sides to move toward the sides, thereby expanding the fabric. Simultaneously, the clamping device and the lifting mechanism work together to firmly clamp the ends of the fabric. The piston rod of the third hydraulic cylinder 16 in the lifting mechanism pushes the first moving block 21, which drives the first clamping roller 25 downward to clamp the fabric together with the second clamping roller 28. As the carrier box 3 expands, the fabric is gradually flattened. During the fabric flattening process, the operator can observe the fabric tension and flatness and adjust the extension and retraction speed of the piston rod of the first hydraulic cylinder 9 to ensure that the fabric is not overstretched or wrinkled during the flattening process. At the same time, the control system can monitor the tension changes of the cloth in real time and automatically adjust the working parameters of the first hydraulic cylinder 9 according to the monitoring results;

[0046] 3. Auxiliary support: The lifting limit mechanism starts working, and the piston rod of the second hydraulic cylinder 13 installed on both sides of the bottom of the protective box 7 extends, pushing the vertical rod 8 upward. The vertical rod 8 drives the support roller 6 to rise, providing auxiliary and stable support for the lower end of the flattened fabric, ensuring that the fabric remains flat during the inspection process; 4. Color difference detection: The detection unit 29 starts working, and the LED lighting fixtures therein provide stable lighting conditions for detection. The color difference detector accurately detects the color of the fabric and transmits the detection data to the control system in real time. The detection sensor is used to monitor the state of the fabric and environmental parameters to ensure the accuracy of the detection results. During the rising process of the support roller 6, the control system can accurately adjust the height of the support roller 6 according to the thickness and tension of the fabric, so that the contact pressure between the support roller 6 and the fabric is maintained appropriately, which can provide effective support without causing excessive squeezing of the fabric. At the same time, the support roller 6 can rotate synchronously according to the moving speed of the fabric to reduce the friction between the fabric and the support roller 6;

[0047] 5. Data Analysis and Result Output: The control system analyzes and processes the data transmitted by the colorimeter and outputs the test results in an intuitive manner, such as displaying them on a screen or generating a detailed test report for the operator's reference. The control system utilizes advanced data analysis algorithms to quickly and accurately analyze and process test data. Test results can be output in a variety of formats, such as numbers, charts, and color comparisons, allowing operators to intuitively understand the color differences of the fabric. Furthermore, the test report can include detailed information such as test parameters, test results, and judgment criteria, providing a strong basis for fabric quality control.

[0048] The above are only preferred specific embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with this technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solutions and inventive concepts of the present invention, should be covered by the scope of protection of the present invention.
