Description

Technical Field

[0001] The present invention relates to the technical field of detection devices, and in particular to a textile fiber composition detection device and a detection method. Background Art

[0002] Traditional clothing is often blended, making it difficult to clearly define its composition. Textile fibers, whether natural or chemical, vary greatly in fineness and cross-sectional shape. A fabric fiber composition detection device is used to detect and analyze the proportions of various fiber components in textiles. With the development of the textile industry, textiles are becoming increasingly diverse, with continuous innovation in fiber types and materials. Therefore, accurate testing of textile composition has become increasingly important. Textile composition analysis not only impacts product quality and safety but also directly influences the market positioning and pricing of textiles.

[0003] When testing the composition of textiles, their surfaces typically need to be flattened to ensure the accuracy and consistency of the test results. Existing textile flattening technologies rely primarily on pulling the textile at multiple points to achieve the desired flattening effect. This stretching at multiple points can easily result in uneven force on the textile surface, causing localized surface bends and wrinkles. This can lead to misjudgment of fiber type or surface characteristics during subsequent observation under an optical microscope, compromising the accuracy of test results. Summary of the Invention

When the first arc block and the second arc block move away from the second magnetic ring, the textile fabric between the two will be straightened and flattened. Through this arrangement, when the textile fabric is straightened and flattened, the tension on its surface is more uniform, avoiding the generation of bending and wrinkles on the local surface of the textile fabric due to uneven tension, ensuring that the fiber type or surface characteristics of the textile fabric are clear under the detection of the optical detection lens, and ensuring the accuracy of the detection result.

[0017] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0018] The existing detection device straightens the textile at multiple points, which easily causes uneven force on the textile surface, causing local bending and wrinkling of the textile surface, thereby affecting the subsequent detection effect. In order to solve this problem, the present application discloses a textile fiber composition detection device, such as Figure 1 As shown, it includes: an optical detector 100, a carrying component 200, and a flattening component 300.

[0019] like Figure 1As shown, the optical detector 100 is internally provided with an optical detection lens, which can take pictures of the outer surface of the textile fabric 500 and collect images. The inspector then transmits the image information to the database for comparison to determine the composition information of the inspected textile fabric 500.

[0020] In order to fix the textile fabric 500 to be inspected directly below the optical inspection lens of the optical detector 100, in a further solution, as shown in FIG. Figure 2 and Figure 3 As shown, a carrying assembly 200 is provided on the optical detector 100, and the carrying assembly 200 includes: a base 230, a second magnetic ring 220 and a first magnetic ring 210. The base 230 is provided on the optical detector 100, and is located directly below the optical detection lens. The second magnetic ring 220 is fixedly mounted on the top of the base 230. The textile fabric 500 is provided on the upper surface of the second magnetic ring 220. The first magnetic ring 210 is provided above the textile fabric 500. The first magnetic ring 210 is configured so that when the second magnetic ring 220 attracts the textile fabric 500 through magnetic attraction, the first magnetic ring 210 is provided. When the textile cloth 500 is placed on the upper surface of the second magnetic ring 220, the textile cloth 500 to be detected can be quickly fixed directly under the optical detection lens through this device. It should be noted that when the textile cloth 500 is placed on the upper surface of the second magnetic ring 220, the textile cloth 500 is approximately located in the middle of the second magnetic ring 220. At the same time, the first magnetic ring 210 also needs to be placed roughly in the middle of the second magnetic ring 220, so that the optical detection lens can detect the textile cloth 500 at the hole position in the middle of the first magnetic ring 210.

[0021] In order to ensure that the surface of the textile fabric 500 is smooth and wrinkle-free during testing, Figure 3 and Figure 4 As shown, a flattening assembly 300 is provided on the bearing assembly 200 , and the flattening assembly 300 includes: a plurality of first arc blocks 340 , a plurality of second arc blocks 350 , a plurality of rods 330 , a mounting ring 310 and a turntable 320 , and a driving assembly 400 for driving the turntable 320 to rotate.

[0022] like Figure 4 and Figure 5As shown, the mounting ring 310 is fixedly mounted on the top of the base 230, and a circular groove 311 is provided on the upper surface of the middle position of the mounting ring 310. A plurality of first arc blocks 340 and a second arc block 350 are provided inside the circular groove 311. The plurality of second arc blocks 350 are respectively provided between two adjacent first arc blocks 340. The textile fabric 500 is provided on the upper surfaces of the first arc blocks 340 and the second arc blocks 350. The upper surfaces of the first arc blocks 340 and the second arc blocks 350 are provided flush with the upper surface of the second magnetic ring 220. When the first magnetic ring 210 is surrounded by the second magnetic ring 220, the second arc blocks 350 are provided flush with the upper surface of the second magnetic ring 220. During magnetic attraction, the textile fabric 500 can be pressed against the upper surfaces of the first arc block 340 and the second arc block 350, so that friction is generated between the textile fabric 500 and the first arc block 340 and the second arc block 350 respectively. Because the suction force of the first magnetic ring 210 when being magnetically attracted by the second magnetic ring 220 is constant, and the radial thickness of the first arc block 340 and the second arc block 350 are set to be the same, the friction generated above is also constant, which facilitates the subsequent radial straightening and flattening of the textile fabric 500 along the circumferential direction of the first magnetic ring 210. In order for the first magnetic ring 210 to completely press and compress the textile fabric 500, as shown in FIG. Figure 2 As shown, the second magnetic ring 220 is disposed inside the circular groove 311 and co-centered therewith, and the first magnetic ring 210 completely covers the circular groove 311 .

[0023] It should be noted that when the first arc block 340 and the second arc block 350 straighten and flatten the textile fabric 500 through friction, when the pulling force reaches a certain value, the first arc block 340 and the second arc block 350 and the lower surface of the textile fabric 500 can slide relative to each other to prevent the textile fabric 500 from being excessively stretched and deformed.

[0024] In order to drive the first arc block 340 and the second arc block 350 to move, the textile fabric 500 is radially straightened and flattened, such as Figure 5 As shown, the plurality of rods 330 are fixedly mounted on the outer surfaces of the arcs of the plurality of first arc blocks 340 and the second arc blocks 350, respectively. Figure 7 As shown, a plurality of holes 312 are equidistantly provided on the inner wall of the circular groove 311 in the circumferential direction, and the rod body 330 is slidably installed on the inner wall of the hole 312. The outer shapes of the hole 312 and the rod body 330 are both square, so that the rod body 330 can only move along its axial direction. A turntable 320 is rotatably installed on the outer surface of the circumference of the mounting ring 310, and a plurality of through grooves 321 are equidistantly provided on the upper surface of the turntable 320 in the circumferential direction. A guide post 331 is fixedly installed on the lower surface of the plurality of rod bodies 330 away from the end of the first arc block 340. The guide post 331 is slidably installed on the inner wall of the through groove 321. When at least one component in the driving assembly 400 drives the turntable 320 as shown in FIG. Figure 6As shown, when the turntable 320 rotates counterclockwise, the through slot 321 drives the through slot 321 to move counterclockwise with the center of the turntable 320 as the rotation center. The through slot 321 drives the rod body 330 to move away from the second magnetic ring 220 through the guide column 331, and drives the multiple first arc blocks 340 and second arc blocks 350 to move away from the second magnetic ring 220 through the rod body 330. Due to the friction between the first arc blocks 340 and the second arc blocks 350 and the textile fabric 500, when the first arc blocks 340 and the second arc blocks 350 move away from the second magnetic ring 220, the textile fabric 500 between the two will be straightened and flattened. Through this arrangement, when the textile fabric 500 is straightened and flattened, the tension on its surface is more uniform, thereby avoiding the generation of bending and wrinkles on the local surface of the textile fabric 500 due to uneven tension, ensuring that the fiber type or surface characteristics of the textile fabric 500 are clear under the inspection of the optical inspection lens, and ensuring the accuracy of the inspection result.

[0025] In order to drive at least one component of the assembly 400 to drive the turntable 320 Figure 6 Turn counterclockwise as shown, Figure 8 As shown, the driving assembly 400 includes an inflator 410 , a first column 430 , a second column 440 and an air guide tube 450 .

[0026] like Figure 8 As shown, the second column 440 is fixedly connected to the circumferential outer surface of the mounting ring 310, the first column 430 is fixedly connected to the lower surface of the turntable 320, the inner wall of the inflatable cylinder 410 is slidably mounted with a piston plate 421, the outer surface of one side of the piston plate 421 is fixedly mounted with a telescopic rod 420, one end of the inflatable cylinder 410 is provided with an opening, one end of the telescopic rod 420 passes through the opening and is rotatably mounted with the first column 430, the other end of the inflatable cylinder 410 is rotatably mounted with the second column 440, and the outer surface of the inflatable cylinder 410 is fixedly connected with a one-way air inlet valve 413, as shown in FIG. Figure 10As shown, the outer surface of the inflatable cylinder 410 is provided with an exhaust valve 411, and a cavity is formed between the bottom wall of the inflatable cylinder 410 and the piston plate 421. The exhaust valve 411 and the one-way air inlet valve 413 are both connected to the inside of the cavity. External compressed air is filled into the cavity inside the inflatable cylinder 410 through the one-way air inlet valve 413. When the compressed air continues to enter the cavity, it pushes the piston plate 421 to move toward the first column 430. The piston plate 421 drives the telescopic rod 420 to move toward the first column 430. A gap is set between the telescopic rod 420 and the inner wall of the retaining ring 412, so that the inflatable cylinder 410 can be opened. The air at the other end of the air cylinder 410 can circulate normally. Through the cooperation of the telescopic rod 420 and the first column 430, the telescopic rod 420 can push the turntable 320 to rotate counterclockwise. Because the one-way air intake valve 413 can only intake air in one direction, the air entering the cavity of the air cylinder 410 will be kept inside it, so that the turntable 320 remains in its current position. In order to enable the turntable 320 to rotate in the opposite direction and reset, when the air in the cavity of the air cylinder 410 needs to be released, the inspector opens the exhaust valve 411 to discharge the air inside the air cylinder 410, and closes the exhaust valve 411 after the air is discharged.

[0027] Because the fiber tissue inside the part of the textile fabric 500 is arranged very tightly when it is reproduced, that is, the adjacent fiber lines are closely together, in order to allow the optical detection lens to clearly capture the individual fiber lines when collecting image information, the fiber lines inside the textile fabric 500 can be separated by appropriate tension while the textile fabric 500 is straightened and flattened, so that there are gaps between the adjacent fiber lines, so that a clearer image can be collected later. To achieve this purpose, in a further solution, as shown in FIG. Figure 8 and Figure 9 As shown, the outer surface of the base 230 is fixedly connected with an air guide tube 450, and an air hole 490 is opened inside the base 230. One end of the air guide tube 450 passes through the outer surface of the base 230 and is connected to the air hole 490. Figure 3 As shown, by covering the upper surface of the second magnetic ring 220 with the textile cloth 500, a cavity is formed inside the second magnetic ring 220, as shown in FIG. Figure 4As shown, the air outlet end of the air hole 490 is arranged between the inner walls of the second magnetic ring 220 and is connected to the cavity, the air inlet end of the air guide tube 450 is fixedly installed with an air inlet solenoid valve 470, and the air inlet end of the one-way air inlet valve 413 is fixedly connected to the air pipe 460, and the other end of the air pipe 460 is connected to the outer surface of the air guide tube 450. The air hole 490 is connected to the interior of the inflatable cylinder 410 through the air guide tube 450, the air pipe 460 and the one-way air inlet valve 413. The inspector is straightening and expanding the air. Before unrolling the textile fabric 500, connect an external air pump to the air inlet end of the air inlet solenoid valve 470 through a connecting pipe. The air pump provides constant-pressure compressed air. When the textile fabric 500 needs to be unfolded and straightened, the air inlet solenoid valve 470 is turned on, allowing the compressed air to enter the air hole 490 through the air inlet solenoid valve 470 and the air guide tube 450, and then be discharged from the air outlet end of the air hole 490 into the cavity between the textile fabric 500 and the second magnetic ring 220. Because the textile fabric 500 is pressed against the upper surface of the second magnetic ring 220 by the first magnetic ring 210, the air entering the cavity is difficult to be discharged in time, causing the pressure inside the cavity to rise. Because the cavity is under pressure, the air guide tube 450 is also under pressure, and some air will enter the cavity of the inflator 410 through the air tube 460 and the one-way air inlet valve 413. The compressed air pushes the piston plate 421 to move toward the first column 430, and the piston plate 421 drives the telescopic rod 420 to move toward the first column 430. Through the cooperation between the telescopic rod 420 and the first column 430, the telescopic rod 420 can push the turntable 320 to rotate counterclockwise. The rotation of the turntable 320 can straighten and unfold the textile fabric 500 while pulling a certain gap between the fiber lines inside the textile fabric 500. At this time, because there are gaps on the surface of the textile fabric 500, the air can be discharged from these gaps, thereby reducing the air pressure inside the cavity.

[0028] In order to ensure that no air enters the cavity of the inflator 410 after the air pressure drops to a fixed value, a retaining ring 412 is fixedly installed on the inner wall of the inflator 410 near the opening, and a spring 480 is sleeved on the outer surface of the telescopic rod 420. The spring 480 is arranged between the retaining ring 412 and the piston plate 421. When the air pressure inside the cavity reaches a fixed value, the pressure in the cavity of the inflator 410 is balanced due to the force of the spring 480, and compressed air will no longer enter the cavity of the inflator 410. At this time, the turntable 320 stops rotating and the inspector closes the air inlet solenoid valve 470. Through this arrangement, the textile fabric 500 is straightened and unfolded, and the fiber lines that can be pulled to its surface are separated to create a gap. By separating the fiber lines on the surface of the textile fabric 500, the optical detection lens can collect clearer and more complete image information of a single fiber line, thereby further improving the accuracy of the detection data.

[0029] It should be noted that when compressed air initially enters the cavity of the textile fabric 500, the surface of the textile fabric 500 will bulge due to the pressure. When the pressure drops to a fixed value, the surface of the textile fabric 500 will return to being flat by pulling it, and will not affect subsequent image acquisition.

[0030] When the textile fabric 500 is stretched and stretched, the two adjacent first arc blocks 340 will move away from the second magnetic ring 220. Therefore, a gap 600 will be formed between the adjacent ends of the two first arc blocks 340, and as they move, the gap 600 will gradually increase. This results in the textile fabric 500 in this area being unable to withstand the pressure from the first magnetic ring 210, and thus unable to generate friction with the first arc blocks 340, thereby preventing the textile fabric 500 in this area from being subjected to tension, ultimately causing the surface of the textile fabric 500 to become more wrinkled. Figure 5 As shown, a second arc block 350 is provided between two adjacent first arc blocks 340, and the second arc block 350 and the adjacent ends of the two adjacent first arc blocks 340 are provided with the same overlapping distance. When there is an overlapping distance, the upper surface of the overlapping position of the second arc block 350 and the first arc block 340 contacts the lower surface of the textile fabric 500 the most, so the friction force on the textile fabric 500 in the overlapping area is also the largest, resulting in the largest pulling force at this position when the textile fabric 500 is straightened and unfolded, causing the textile fabric 500 to be subjected to uneven pulling force, thereby generating bending and wrinkles. In order to avoid this problem, as shown in FIG. Figure 11 As shown, the radial thickness of the first arc block 340 and the second arc block 350 are set to be the same, and a first groove 341 is opened on the upper surface of the first arc block 340, and a second groove 351 is opened on the upper surface of the second arc block 350. The first groove 341 and the two adjacent second grooves 351 will have the same overlapping distance as the second arc block 350 and the first arc block 340 overlap. The first groove 341 is streamlined and thin in the middle and wide at both ends, and the second groove 351 is streamlined and thin in the middle and wide at both ends. The groove widths of the first groove 341 and the second groove 351 near the middle area of ​​the arc are set to be the same, so that the upper surfaces of the first arc block 340 and the second arc block 350 near the middle position of the arc are also the same in contact with the textile fabric 500. When the first arc block 340 and the second arc block 350 are straightened and flattened on the textile fabric 500, the first arc block 340 and the second arc block 350 will move relative to each other, as shown in FIG. Figure 6 and Figure 11As shown, when the first arc block 340 and the second arc block 350 move to a position close to the end point, as the overlapping distance between the two decreases, the overlapping distance between the first groove 341 and the second groove 351 also decreases. At this time, the contact area between the upper surface of the overlapping area of ​​the first arc block 340 and the second arc block 350 and the textile fabric 500 is only slightly different from the contact area between the upper surface of the non-overlapping area and the textile fabric 500, so that the friction force between the contact surfaces of the first arc block 340 and the second arc block 350 and the textile fabric 500 is within a reasonable error. This ensures that when the first arc block 340 and the second arc block 350 stretch and flatten the textile fabric 500, the change in the radial tension of the second magnetic ring 220 in the circumferential direction remains within a very small range, thereby achieving uniform distribution of force on the fabric. A method for using a textile fiber composition detection device comprises the following steps: S1: The textile fabric 500 is placed on the upper surface of the second magnetic ring 220, and the first magnetic ring 210 is placed above the textile fabric 500. The first magnetic ring 210 is configured to press the textile fabric 500 against the upper surface of the second magnetic ring 220 when the second magnetic ring 220 is attracted by magnetic attraction, thereby fixing the position of the textile fabric 500. S2: The fixed textile fabric 500 is placed directly below the optical inspection lens inside the optical inspection instrument 100, and an image of the outer surface of the textile fabric 500 is captured. The inspector then transmits the image information to a database for comparison to determine the composition information of the inspected textile fabric 500. S3: In order to ensure that the surface of the textile fabric 500 is flat and wrinkle-free during testing, when the first magnetic ring 210 is magnetically attracted by the second magnetic ring 220, the textile fabric 500 can be pressed against the upper surfaces of the first arc block 340 and the second arc block 350, so that friction is generated between the textile fabric 500 and the first arc block 340 and the second arc block 350, respectively, to facilitate subsequent radial straightening and flattening of the textile fabric 500 along the circumferential direction of the first magnetic ring 210; S4: The driving assembly 400 is used to make the turntable 320 drive the through slot 321 to move counterclockwise with the center of the turntable 320 as the rotation center. The through slot 321 drives the rod body 330 to move away from the second magnetic ring 220 through the guide column 331. The rod body 330 drives multiple first arc blocks 340 and second arc blocks 350 to move away from the second magnetic ring 220. Due to the friction between the first arc blocks 340 and the second arc blocks 350 and the textile fabric 500, when the first arc blocks 340 and the second arc blocks 350 move away from the second magnetic ring 220, the textile fabric 500 between the two will be straightened and flattened.
