Description

Technical Field

[0001] This invention relates to the field of component detection technology, and more specifically to a textile fiber component detection device and detection method. Background Technology

[0002] Textiles refer to materials that process fibers into yarns, fabrics, or finished products (such as clothing, home textiles, and industrial fabrics) through technologies such as spinning, weaving, knitting, and non-woven fabric production. Raw materials include natural fibers (cotton, linen, wool, silk, etc.) and chemical fibers (polyester, nylon, acrylic, etc.). Traditional clothing often uses blended processing, making it difficult to clearly define the composition when measuring garment components. Furthermore, textile fibers, whether natural or chemical, vary greatly in fineness and cross-sectional shape. A textile fiber composition analysis 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, and fiber types and materials are constantly being innovated. Therefore, accurate detection of textile composition has become particularly important. The analysis of textile composition not only affects product quality and safety but also directly impacts the market positioning and price of textiles. However, when performing composition testing on textiles, it is usually necessary to flatten the surface and fix the flattened textiles with clamps to ensure the accuracy and consistency of the test results. The operation of flattening and then clamping the textiles significantly reduces the textile composition testing rate. At the same time, the clamps used to fix the textiles can easily cause uneven stress on the textile surface, which can cause local bending and wrinkling of the textile surface. This can lead to misjudgment of fiber type or surface characteristics when observed under an optical microscope, thus affecting the accuracy of the test results. Summary of the Invention

[0003] In order to overcome the above-mentioned defects of the prior art, the present invention provides a textile fiber composition detection device and detection method to solve the problems existing in the background art.

[0004] This invention provides a textile fiber composition detection device, including a detection platform. A support column is fixedly connected to one side of the top of the detection platform, and a microscope observation bracket is fixedly connected to the top of the support column. A limiting flattening seat is fixedly connected to the center of the top of the detection platform. Air guide boxes are fixedly connected to both the left and right side walls of the detection platform. Negative pressure fans are installed inside the air guide boxes on both sides of the detection platform. Air guide hoses are fixedly connected to the top of the air guide boxes. An auxiliary flattening bracket is fixedly connected to the other end of each air guide hose. The auxiliary flattening bracket is located vertically above the limiting flattening seat and is movably connected to the inside of the support column near the detection platform. An adjustment component is installed inside the detection platform below the support column.

[0005] Furthermore, a rectangular slide groove is provided inside the support column, and a lifting threaded rod is provided inside the rectangular slide groove. The non-threaded sections at both ends of the lifting threaded rod are rotatably connected to the top and bottom of the rectangular slide groove, respectively. A turbine is fixedly connected to the bottom end of the lifting threaded rod, and the turbine meshes with the adjustment component for transmission. Arc-shaped limiting slide grooves are provided on the left and right inner sidewalls of the rectangular slide groove.

[0006] Furthermore, the adjustment component includes an adjustment rod, which passes through the side wall of the testing platform and is fixedly connected to a rotary knob. An adjustment thread is formed on the surface of the adjustment rod near the bottom of the lifting threaded rod. The turbine meshes with the adjustment thread, and both ends of the adjustment rod are rotatably connected to the testing platform. By including the adjustment component, lifting threaded rod, auxiliary flattening bracket, and limiting flattening seat, it is advantageous to rotate the lifting threaded rod via the adjustment component during fiber composition testing of textiles. This causes the lifting threaded rod to lower the auxiliary flattening bracket, automatically pushing and flattening the textile at the top of the limiting flattening seat. The operation is simple and convenient, and the flattened textile surface is evenly stressed, avoiding interference with subsequent observation under an optical microscope, thereby improving the accuracy of the test results.

[0007] Furthermore, the auxiliary flattening support includes a flattening rubber ring. A lifting rod is fixedly connected to the side of the flattening rubber ring closest to the support column. A threaded tube is fixedly connected to the end of the lifting rod away from the flattening rubber ring. The threaded tube is helically connected to the lifting threaded rod through internal matching threads. A cylindrical inner cavity is formed inside the flattening rubber ring, and regularly arranged air jet holes are formed around the bottom of the flattening rubber ring, communicating with the cylindrical inner cavity. The auxiliary flattening support facilitates the rapid flattening of textiles to be inspected, improving the convenience of actual testing.

[0008] Furthermore, the air jets are all inclined at a 30-degree angle towards the bottom of the center of the flattened rubber ring, and the cylindrical inner cavity is also inclined at a 30-degree angle towards the bottom of the center of the flattened rubber ring, which helps to clean the surface of the textile to be tested, thereby improving its surface cleanliness.

[0009] Furthermore, the limiting flattening seat includes a flattening base, an inner negative pressure cavity is formed inside the flattening base, exhaust holes are formed on both sides of the inner wall of the inner negative pressure cavity, and first suction holes are formed in a regular arrangement around the top of the flattening base. The first suction holes are connected to the inner negative pressure cavity. The limiting flattening seat facilitates the rapid fixation and restraint of the textile to be tested, preventing the textile from slipping during the testing process.

[0010] Furthermore, a support observation head is fixedly connected to the top of the flattened base. The support observation head has regularly arranged second air intake holes inside and near its perimeter. The second air intake holes are interconnected with the inside of the negative pressure cavity.

[0011] The present invention also provides a detection method for the above-mentioned textile fiber composition detection device, comprising the following steps; S1. First, when testing the fiber composition of textiles, the textile to be tested is placed on top of the support observation head. Then, the negative pressure fan is activated to extract the air from the negative pressure inner cavity. The air inside the negative pressure inner cavity is then drawn out through the exhaust hole and enters the air guide box. Then, it is sent into the cylindrical inner cavity opened by the flattening rubber ring through the air guide hose at the top of the air guide box. At this time, the textiles on top of the support observation head and the flattening base are adsorbed and fixed through the first and second air intake holes. At the same time, the air inside the cylindrical inner cavity is discharged through the jet hole and sprayed to the top of the textiles on the limit flattening seat. At this time, the dust on the surface of the textiles on the limit flattening seat is blown off by the sprayed air, thereby improving the cleanliness of the surface of the textile to be tested. S2. Then, hold the knob with your right hand and rotate it. This will cause the knob to rotate the adjusting rod and its surface adjusting threads. The adjusting threads will then drive the meshing turbines on one side, which in turn will drive the lifting thread rod to rotate. At this time, the rotation of the lifting thread rod will cause the threaded tube, which is limited by the limiting slide groove, to move up and down in the rectangular slide groove inside the support column. Then, the threaded tube will drive the lifting rod and the flattening rubber ring to move closer to the textile on the top of the limiting flattening seat. Finally, the flattening rubber ring will be placed on the outer wall of the support observation head, thereby flattening the textile on the top of the support observation head. At the same time, the flattening rubber ring will fix and limit the textile on the top of the support observation head, further preventing wrinkles from affecting the accuracy of the detection. Then, the fiber composition of the textile on the top of the limiting flattening seat can be detected by observing the observation lens set below the microscope observation bracket.

[0012] The technical effects and advantages of this invention are as follows: 1. This invention, by incorporating an adjustment component, a lifting threaded rod, an auxiliary flattening bracket, and a limiting flattening seat, facilitates fiber composition testing of textiles. The adjustment component drives the lifting threaded rod to rotate, causing it to lower the auxiliary flattening bracket. This automatically pushes the textile at the top of the limiting flattening seat to the surrounding areas for flattening. The operation is simple and convenient, and the flattened textile surface experiences uniform force, avoiding interference with subsequent observation under an optical microscope and thus improving the accuracy of the test results.

[0013] 2. The present invention, by incorporating an air guide box, a negative pressure fan, an air guide hose, and an auxiliary flattening bracket, facilitates the initial fixation of textiles by adsorption during the flattening process using the negative pressure fan. Simultaneously, the air generated during the adsorption process is delivered into the auxiliary flattening bracket through the air guide hose, allowing the auxiliary flattening bracket to clean the surface of the textile to be tested through air jet holes at the bottom, thereby improving the accuracy of subsequent textile testing.

[0021] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. The textile fiber composition detection device and detection method involved in the present invention are not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] Reference Figures 1-6As shown, the present invention provides a textile fiber composition detection device and detection method, including a detection platform 1, a support column 2 fixedly connected to one side of the top of the detection platform 1, a microscope observation bracket 3 fixedly connected to the top of the support column 2, a limiting flattening seat 4 fixedly connected to the center of the top of the detection platform 1, air guide boxes 5 fixedly connected to both the left and right side walls of the detection platform 1, negative pressure fans 6 are provided inside the air guide boxes 5 fixedly connected to both sides of the detection platform 1, air guide hoses 7 are fixedly connected to the top of the air guide boxes 5, and auxiliary flattening brackets 8 are fixedly connected to the other end of the air guide hoses 7. The auxiliary flattening brackets 8 are located vertically above the limiting flattening seat 4 and are movably connected to the inside of the support column 2 near the detection platform 1. An adjustment component 9 is provided inside the detection platform 1 below the support column 2. The support column 2 has a rectangular slide groove 201 inside, and a lifting threaded rod 10 is installed inside the rectangular slide groove 201. The non-threaded sections at both ends of the lifting threaded rod 10 are rotatably connected to the top and bottom of the rectangular slide groove 201, respectively. A turbine 1001 is fixedly connected to the bottom end of the lifting threaded rod 10, and the turbine 1001 meshes with the adjusting component 9 for transmission. The left and right inner sidewalls of the rectangular slide groove 201 are provided with arc-shaped limiting slide grooves 2011.

[0023] The adjustment assembly 9 includes an adjustment rod 901. One end of the adjustment rod 901 passes through the side wall of the test bench 1 and is fixedly connected to a rotary knob 902. An adjustment thread 903 is provided on the surface of the adjustment rod 901 and near the bottom of the lifting threaded rod 10. The turbine 1001 meshes with the adjustment thread 903. Both ends of the adjustment rod 901 are rotatably connected to the test bench 1. The auxiliary flattening support 8 includes a flattening rubber ring 801. A lifting rod 802 is fixedly connected to the side surface of the flattening rubber ring 801 near the support column 2. A threaded tube 803 is fixedly connected to the end of the lifting rod 802 away from the flattening rubber ring 801. The threaded tube 803 is helically connected to the lifting threaded rod 10 through internal matching threads. A cylindrical inner cavity 804 is opened inside the flattening rubber ring 801. Air jet holes 805 are regularly arranged around the bottom of the flattening rubber ring 801 and communicate with the cylindrical inner cavity 804. The bottom edge of the inner ring of the flattening rubber ring 801 is chamfered to avoid damage to the textile.

[0024] In this embodiment, the auxiliary flattening bracket 8 facilitates the rapid flattening of the textile to be tested, thus improving the convenience of actual testing.

[0025] Among them, the jet holes 805 are all tilted 30 degrees toward the bottom center of the flattened rubber ring 801; In this embodiment, the air jet holes 805 at the bottom of the cylindrical inner cavity 804 are all tilted 30 degrees toward the center bottom of the flattened rubber ring 801, which is beneficial for cleaning the surface of the textile to be tested, thereby improving its surface cleanliness.

[0026] Among them, the limiting flattening seat 4 includes a flattening base 401, a negative pressure inner cavity 402 is opened inside the flattening base 401, exhaust holes 404 are opened on both the left and right sides of the inner wall of the negative pressure inner cavity 402, and first air intake holes 403 are opened on the top four sides of the flattening base 401 in a regular arrangement, and the first air intake holes 403 are connected to the negative pressure inner cavity 402. The flattening base 401 has a fixed support observation head 405 at its top. The support observation head 405 has regularly arranged second air intake holes 406 inside and near its perimeter. The second air intake holes 406 are connected to the negative pressure inner cavity 402. The top edge of the support observation head 405 is chamfered to facilitate the engagement of the flattening rubber ring 801 with the chamfered bottom edge, thereby limiting and fixing the textile while preventing damage to the textile.

[0027] In this embodiment, the limiting flat seat 4 helps to quickly fix and restrict the textile to be tested, preventing the textile from slipping during the testing process.

[0028] Working principle of the invention: S1. First, when performing fiber composition testing on textiles, the textile to be tested is placed on top of the support observation head 405. Then, the motor is started, and the output of the motor drives the negative pressure fan 6 to rotate. The negative pressure fan 6 will then draw out the air inside the negative pressure cavity 402. The air inside the negative pressure cavity 402 is drawn out through the exhaust hole 404 into the air guide box 5, and then sent through the air guide hose 7 at the top of the air guide box 5 into the cylindrical cavity 804 opened in the flattening rubber ring 801. At this time, the textile on top of the support observation head 405 and the flattening base 401 passes through the first air intake hole 403 and the second air intake hole 404. 06 Adsorption and fixation are performed. By setting two air suction holes, it can be ensured that when the textile is adsorbed in the hole area, it means that it is automatically positioned in the standard detection area. The second air suction hole 406 ensures that each test is performed in the same type area of ​​the sample (such as the center of the fabric), avoiding compositional differences caused by different positions (such as the edge and center of the fabric may be different). At the same time, the air inside the cylindrical cavity 804 is discharged through the air jet hole 805 and sprayed to the top of the textile on the top of the limiting flat seat 4. At this time, the dust on the surface of the textile on the top of the limiting flat seat 4 is blown off by the sprayed air, thereby improving the cleanliness of the surface of the textile to be tested. S2. Hold the knob 902 with your right hand and rotate it. This causes the knob 902 to rotate the adjusting rod 901 and its adjusting thread 903. The adjusting thread 903 then drives the meshing turbine 1001 on one side, which in turn drives the lifting threaded rod 10 to rotate. At this time, the rotation of the lifting threaded rod 10 causes the threaded tube 803, which is limited by the limiting slide groove 2011, to move up and down in the rectangular slide groove 201 inside the support column 2. Then, the threaded tube 803 drives the lifting rod 802 and the flattening rubber ring 801 to move closer to the textile on the top of the limiting flattening seat 4. Finally, the flattening rubber ring 801 will be placed on the outer wall of the support observation head 405, thereby flattening the textile on the top of the support observation head 405. At the same time, the flattening rubber ring 801 will fix and restrict the textile on the top of the support observation head 405, further preventing the textile from being flattened. Wrinkles during product inspection affect the accuracy of the inspection. Then, the textile at the top of the limiting flattening seat 4 can be inspected through the observation mirror 301 set below the microscope observation bracket 3 to detect the fiber composition. The observation mirror 301 can be adjusted up and down on the microscope observation bracket. The distance between the microscope observation bracket 3 and the support observation head 405 is fixed. After the monitoring and observation of the textile is completed, the rotary knob 902 is rotated in the opposite direction. The rotary knob 902 will drive the adjusting rod 901 and the adjusting thread 903 on its surface to rotate in the opposite direction. In this way, the adjusting thread 903 will drive the turbine 1001 meshing with it to rotate in the opposite direction. Then, the turbine 1001 will drive the lifting thread rod 10 to rotate in the opposite direction. In this way, the threaded tube 803 will move up and down in the rectangular slide groove 201 inside the support column 2. The threaded tube 803 will drive the lifting rod 802 and the flattening rubber ring 801 away from the limiting flattening seat 4. The observation mirror 301, model AM7013MZT, can quickly observe the plant fibers (cellulose fibers) used in general textiles, as well as the yarn structure, fabric density, surface defects, pilling grade, and dyeing uniformity.

[0029] It should be noted that the control of the negative pressure fan and its motor in this application can all be achieved through automated control using a program set in the control panel, inputting relevant parameters as needed to achieve orderly operation. This control method can be implemented using existing technologies, such as PLCs. Two corrugated pipe protective covers can be fitted onto the lifting threaded rod 10 for dust and moisture protection. The two ends of each corrugated pipe protective cover are fixedly connected to one side of the threaded pipe 803 and the top and bottom of the inner wall of the rectangular slide groove 201, respectively. For ease of assembly, the support column 2 itself can be assembled from two or more components. The rectangular slide groove 201 is a cavity naturally formed after the components are joined, and the threaded pipe 803 can be inserted during the bracket assembly process.
