Description

Technical Field

[0001] This invention relates to the field of fabric testing devices, and more particularly to a device and method for detecting the aurora on the surface of fabrics. Background Technology

[0002] During processing or wearing, fabrics are subject to frequent external friction, pressure, stretching, improper ironing, and improper finishing, all of which can cause changes in the fabric's surface luster, even producing an "aurora" phenomenon. This "aurora" phenomenon detracts from the elegant appearance of clothing, and its visual comfort is generally considered poor, something to be avoided during garment processing and wearing. In clothing, the aurora phenomenon is particularly prone to occur on pure wool and wool-polyester garment fabrics, especially on worsted pure wool and wool-polyester blended outerwear fabrics. Once aurora appears on a fabric, it is very difficult to eliminate.

[0003] In existing technologies, the aurora testing and rating of fabrics mostly adopts the Martindale method for measuring fabric abrasion resistance. However, when using the Martindale method for friction testing, existing devices generate a large amount of static electricity, which attracts airborne particles and dust to the fabric under test. This results in the fabric not being able to be rubbed to the expected degree, and it is also impossible to ensure that all fabrics under test have inconsistent abrasion levels due to particles and dust after the same number of rubs, leading to non-standard testing structures. Summary of the Invention

[0004] This invention overcomes the shortcomings of the prior art and provides a device and method for detecting aurora on the surface of fabrics.

[0005] To achieve the above objectives, the technical solution adopted by the present invention is as follows: a device for detecting the aurora on the surface of a fabric, comprising: a transmission mechanism, a friction mechanism fixedly connected to the transmission mechanism, and a telescopic mechanism fixedly connected to the friction mechanism.

[0006] The transmission mechanism includes a sprocket assembly and a servo motor fixedly connected to the sprocket assembly; the transmission mechanism is used to provide power to drive the friction mechanism to rotate.

[0007] The friction mechanism includes a fabric clamp and a detection clamp, which are arranged symmetrically above and below each other. The detection clamp is fixedly connected to the sprocket assembly. The detection clamp is used to fix or replace the detection piece or combing piece, and the fabric clamp is used to fix or replace the fabric to be inspected.

[0008] The telescopic mechanism is fixedly connected to the fabric clamp. The telescopic mechanism is used to control the lifting and lowering of the fabric clamp. The telescopic mechanism is equipped with metal wires that are connected to the fabric clamp and the ground respectively. The telescopic mechanism is equipped with a display screen for displaying pressure.

[0009] In a preferred embodiment of the present invention, the transmission mechanism further includes a sprocket housing, a sprocket set is evenly arranged inside the sprocket housing, the sprocket housing is rotatably connected to the sprocket set, and a fixed shaft is fixedly connected to the bottom of the sprocket set, the fixed shaft passing through the sprocket housing.

[0010] In a preferred embodiment of the present invention, the sprocket assembly includes a driving sprocket and a driven sprocket, and the output shaft of the servo motor passes through the sprocket housing and is fixedly connected to the driving sprocket; the driving sprocket and the driven sprocket are driven by a chain.

[0011] In a preferred embodiment of the present invention, the detection fixture includes a fixing plate, which is circular in shape and has a convex cross-section. The bottom circumference of the fixing plate is threaded, and the top circumference is provided with a rubber ring. The fixing shaft is fixedly connected to the fixing plate of the detection fixture.

[0012] In a preferred embodiment of the present invention, the detection fixture further includes a fixing ring, which is circular in shape and has an inverted L-shaped cross-section. A threaded groove is provided on the inner side of the fixing ring, and the fixing ring engages with the fixing plate. The detection fixture has the same structure as the fabric fixture.

[0013] In a preferred embodiment of the present invention, the telescopic mechanism includes a sleeve, a base plate fixedly connected to the bottom of the sleeve, the base plate being made of metal, a threaded rod being provided inside the sleeve, the threaded rod being slidably connected to the sleeve, and a rotating plate being rotatably connected to the top of the sleeve, the rotating plate engaging with the threaded rod.

[0014] In a preferred embodiment of the present invention, a metal wire is disposed inside the threaded rod, and the two ends of the metal wire are respectively connected to the base plate and the fixing plate. A support shaft is fixedly connected between the base plate and the sprocket housing.

[0015] A method for detecting aurora on the surface of a fabric includes the following steps:

[0016] S1: Use the inspection fixture to fix the combing part and the fabric fixture to fix the fabric to be inspected. The telescopic mechanism drives the fabric fixture to rise until the combing part contacts the fabric to be inspected.

[0017] S2: The transmission mechanism drives the testing fixture to rotate in one direction, combing the fibers on the fabric to be inspected to the same direction;

[0018] S3: The telescopic mechanism drives the fabric clamp to descend, replacing the combing part on the inspection clamp with the inspection part;

[0019] S4: The telescopic mechanism drives the testing fixture to rise, and the testing fixture squeezes against the fabric fixture. Observe the pressure value on the display screen, and adjust the pressure according to different fabrics to be tested.

[0020] S5: After rubbing, remove the fabric to be inspected, place it in sunlight to observe its condition, and then rate it.

[0021] In a preferred embodiment of the present invention, in S1, the bottom of the combing component is uniformly provided with a plurality of teeth; in S3, the detection component is a woven plain woolen fabric.

[0022] In a preferred embodiment of the present invention, in S5, the rating is divided into no aurora, slight aurora, and severe aurora based on the color depth and variation.

[0023] This invention addresses the shortcomings of the prior art and has the following beneficial effects:

[0024] (1) The present invention provides a detection device and method for the aurora on the surface of fabric. By using the friction mechanism, the telescopic mechanism and the transmission mechanism in cooperation, the pressure intensity can be adjusted according to different fabrics to be tested by the telescopic mechanism during the test, avoiding the need to use the number of frictions to achieve the expected effect, thereby improving the detection efficiency. Furthermore, by changing the combing part and the detection part, the fabric to be tested can be combed and tested separately, thereby effectively improving the accuracy of the test.

[0025] (2) The present invention provides a detection device and method for the aurora on the surface of fabric. By using the cooperation between the fixed plate, the metal wire and the base plate, the static electricity generated during friction is transmitted to the metal wire through the fixed plate and finally conducted to the ground through the base plate. This effectively avoids the adsorption of particles and dust in the air during the friction test, so that the expected effect cannot be achieved in the specified friction process. Under the same number of frictions as other test pieces, the presence of particulate matter leads to inaccurate test results.

[0026] (3) The present invention provides a detection device and method for the aurora on the surface of fabric. Through the cooperation between the detection fixture, the combing part and the fabric to be inspected, the combing part is used to comb the fabric to be inspected first. The combing part has several teeth. When it is rotating and combing, the fibers on the fabric to be inspected can be aligned in the same direction. Then, friction detection is performed. This effectively avoids the situation where the fibers on the surface of the fabric to be inspected are messy during friction detection, which causes the fibers to overlap and not be rubbed. This results in some fibers not being rubbed and some fibers being rubbed repeatedly, thereby effectively improving the accuracy of detection. Attached Figure Description

Those skilled in the art will understand the specific meaning of the above terms in this application based on the specific circumstances.

[0040] like Figure 1 , Figure 2 and Figure 3 As shown, a device for detecting aurora on the surface of a fabric includes: a transmission mechanism 1, a friction mechanism 2 fixedly connected to the transmission mechanism 1, and a telescopic mechanism 3 fixedly connected to the friction mechanism 2.

[0041] It should be noted that the transmission mechanism 1 is the power source of the entire testing device, driving the friction mechanism 2 to rotate. The telescopic mechanism 3 is used to adjust the distance between the friction mechanisms 2. When different pressures are required for friction testing, the telescopic mechanism 3 is used to adjust the distance between the friction mechanisms 2 to generate pressure, thereby achieving the pressure required for friction during testing and ensuring the accuracy of the test.

[0042] The transmission mechanism 1 includes a sprocket assembly 10 and a servo motor 11 fixedly connected to the sprocket assembly 10; the transmission mechanism 1 is used to provide power to drive the friction mechanism 2 to rotate.

[0043] In a preferred embodiment of the present invention, the transmission mechanism 1 further includes a sprocket housing 12, and a sprocket set 10 is evenly arranged inside the sprocket housing 12. The sprocket housing 12 is rotatably connected to the sprocket set 10, and a fixed shaft 13 is fixedly connected to the bottom of the sprocket set 10, the fixed shaft 13 passing through the sprocket housing 12.

[0044] In a preferred embodiment of the present invention, the sprocket assembly 10 includes a driving sprocket and a driven sprocket, and the output shaft of the servo motor 11 passes through the sprocket housing 12 and is fixedly connected to the driving sprocket; the driving sprocket and the driven sprocket are driven by a chain.

[0045] It should be noted that the transmission mechanism 1 is composed of a servo motor 11 as the power source, a sprocket assembly 10 as the driving component, and a fixed shaft 13 as the transmission component. The servo motor 11 is located at the bottom of the outer side of the sprocket housing 12. The sprocket assembly 10 is rotatably connected to the inner side of the sprocket housing 12. The sprocket assembly 10 consists of one driving sprocket and five driven sprockets. The driving sprocket and the driven sprockets are driven by a chain. The output shaft of the servo motor 11 passes through the sprocket housing 12 and is fixedly connected to the bottom of the driving sprocket. The fixed shaft 13 is fixedly connected to the bottom of the five driven sprockets. The fixed shaft 13 passes through the sprocket housing 12 and is slidably connected to the sprocket housing 12. When the equipment is running, the servo motor 11 starts, thereby driving the driving sprocket to rotate. The driving sprocket drives the driven sprockets to rotate through the chain, and then the driven sprockets drive the fixed shaft 13 to rotate.

[0046] The friction mechanism 2 includes a fabric clamp 20 and a detection clamp 21, which are arranged symmetrically in the upper and lower positions. The detection clamp 21 is fixedly connected to the sprocket assembly 10. The detection clamp 21 is used to fix or replace the detection piece or combing piece, and the fabric clamp 20 is used to fix or replace the fabric to be inspected.

[0047] In a preferred embodiment of the present invention, the detection fixture 21 includes a fixing plate 22, which is in the shape of a circular plate with a convex cross-section. The bottom circumference of the fixing plate 22 is threaded, and the top circumference is provided with a rubber ring 23. The fixing shaft 13 is fixedly connected to the fixing plate 22 of the detection fixture 21.

[0048] In a preferred embodiment of the present invention, the detection fixture 21 further includes a fixing ring 24, which is formed in a circular shape and has an inverted L-shaped cross-section. A threaded groove is provided on the inner side of the fixing ring 24, and the fixing ring 24 engages with the fixing plate 22. The detection fixture 21 has the same structure as the fabric fixture 20.

[0049] It should be noted that the inspection fixture 21 consists of a fixed plate 22, a fixed ring 24, and a rubber ring 23. The fixed plate 22 has a convex cross-section, similar to a small-diameter circular plate fixed to a large-diameter circular plate. The large and small diameters are only symbolic comparisons used to represent the shape of the fixed plate 22. Threads are provided on the outer circumference of the bottom of the fixed plate 22. The fixed ring 24 has an inverted L-shaped cross-section, and threaded grooves are also provided on its inner side. The threads on the fixed ring 24 engage with the threads on the fixed plate 22. The rubber ring 23 is located on the smaller circumference at the top of the fixed plate 22. The rubber ring 23 can slide up and down or be removed from the fixed plate 22. When the fixed ring 24 is fitted onto the fixed plate 22, the rubber ring 23 is stretched. The inspection fixture 21 has the same structure as the fabric fixture 20. The inspection fixture 21 is used to fix the inspection piece or combing piece, while the fabric fixture 20 is used to fix the fabric to be inspected. The inspection fixture 21 and the fabric fixture 20 are arranged symmetrically. The bottom of the fixed shaft 13 is fixedly connected to the inspection fixture 21 by a threaded fixing plate 22. That is, the bottom of the fixed shaft 13 is threaded, and one side of the fixing plate 22 is threaded. The two are fixedly connected by the engagement of the threaded hole of the fixing plate 22 and the thread of the fixed shaft 13. During the inspection, the friction mechanism 2 is removed, and then the fabric, combing part or friction material to be inspected is laid flat on the fixing plate 22 to avoid wrinkles. Then, the rubber ring 23 is placed on the fixing plate 22, and then pressed down and stretched in all directions to fit around the circumference of the fixing plate 22. After it fits around the circumference of the fixing plate 22, it is pressed down again, which plays an auxiliary role in fixing under the action of friction. Then, the fixing ring 24 is put on the fixing plate 22, and the threads on the fixing ring 24 and the fixing plate 22 are engaged. While tightening the engagement, the rubber ring 23 between the fixing plate 22 and the fixing ring 24 is clamped. At this time, the fabric, combing part or friction material to be inspected is fixed. Then the friction mechanism 2 is reinstalled.

[0050] The telescopic mechanism 3 is fixedly connected to the fabric clamp 20. The telescopic mechanism 3 is used to control the lifting and lowering of the fabric clamp 20. The telescopic mechanism 3 is equipped with a metal wire 30, which is connected to the fabric clamp 20 and the ground respectively. The telescopic mechanism 3 is equipped with a display screen for displaying pressure.

[0051] In a preferred embodiment of the present invention, the telescopic mechanism 3 includes a sleeve 31, a base plate 32 fixedly connected to the bottom of the sleeve 31, the base plate 32 being made of metal, a threaded rod 35 being provided inside the sleeve 31, the threaded rod 35 being slidably connected to the sleeve 31, and a rotating plate 34 being rotatably connected to the top of the sleeve 31, the rotating plate 34 engaging with the threaded rod 35.

[0052] In a preferred embodiment of the present invention, a metal wire 30 is disposed inside the threaded rod 35, and the two ends of the metal wire 30 are respectively connected to the base plate 32 and the fixing plate 22. A support shaft 33 is fixedly connected between the base plate 32 and the sprocket housing 12.

[0053] It should be noted that the telescopic mechanism 3 mainly consists of a sleeve 31, a threaded rod 35, and a rotating plate 34. The threaded rod 35 is located inside the sleeve 31 and passes through the middle of the sleeve 31, and is slidably connected to the sleeve 31, meaning the threaded rod 35 can slide up and down inside the sleeve 31. The rotating plate 34 is located at the top of the sleeve 31 and is rotatably connected to the sleeve 31, meaning the rotating plate 34 can rotate at the top of the sleeve 31. A threaded hole is provided in the middle of the rotating plate 34, and the threaded hole on the rotating plate 34 engages with the threaded rod 35, thereby allowing the rotating plate 34 to rotate clockwise or counterclockwise. Do not move the threaded rod 35 up or down inside the sleeve 31. The top of the threaded rod 35 is also fixedly connected to the inspection fixture by threads. That is, a small threaded rod 35 is provided at the top of the threaded rod 35. A threaded hole is opened on the fixing plate 22 of the inspection fixture to engage with it. During fixing, the two are fixed by threading them together. A through hole is opened in the middle of the threaded rod 35, and a metal wire 30 is placed in the middle of the through hole. A base plate 32 is fixedly connected to the bottom of the sleeve 31. Both the base plate 32 and the fixing plate 22 in the inspection fixture are made of conductive metal. The two ends of the metal wire 30 are always connected to the base plate 32 and the inspection fixture respectively. The fixed plate 22 of the substitute inspection fixture is in contact with the base plate 32 and the sprocket housing 12. A support shaft 33 is provided between the base plate 32 and the sprocket housing 12. The two ends of the support shaft 33 are fixedly connected to the sprocket housing 12 and the base plate 32, respectively. The tightening direction of the fixed plate 22 in the substitute inspection fixture and the detection fixture 21 is clockwise. During the detection, the rotation direction of the friction is also clockwise. The display plate is fixedly connected to the outside of the sleeve 31. A pressure sensor is provided on the fixed plate 22 of the substitute inspection fixture. During the detection, the rotation plate 34 is rotated to control the up and down movement of the threaded rod 35, thereby driving the substitute inspection fixture to move up and down, so that the surface The fixing plates 22 of the material clamp 20 and the detection clamp 21 are squeezed together, thereby generating a certain pressure on the material to be inspected. The pressure value varies depending on the material to be inspected. At the same time, the pressure value is converted into a numerical value and displayed on the display panel by the pressure sensor. During friction detection, static electricity is generated between the detection piece and the material to be inspected. The fixing plate 22 of the material to be inspected is made of metal. When static electricity is generated, the metal wire 30 is made of copper wire, which has good conductivity. At the same time as static electricity is generated, the static electricity is quickly conducted to the base plate 32 and then transmitted from the point to the ground.

[0054] A method for detecting aurora on the surface of a fabric includes the following steps:

[0055] S1: Use the inspection clamp 21 to fix the combing part and the fabric clamp 20 to fix the fabric to be inspected. The telescopic mechanism 3 drives the fabric clamp 20 to rise until the combing part contacts the fabric to be inspected.

[0056] S2: The transmission mechanism 1 drives the detection fixture 21 to rotate in one direction, so that the fibers on the fabric to be inspected are combed to the same direction.

[0057] S3: The telescopic mechanism 3 drives the fabric clamp 20 to descend, replacing the combing part on the detection clamp 21 with the detection part;

[0058] S4: The telescopic mechanism 3 drives the detection fixture 21 to rise, and the detection fixture 21 is squeezed against the fabric fixture 20. Observe the pressure value on the display screen, and adjust the pressure according to different fabrics to be inspected.

[0059] It should be noted that different fabrics require different pressure values: 4-6 kPa for apparel fabrics and 8-10 kPa for decorative fabrics.

[0060] S5: After rubbing, remove the fabric to be inspected, place it in sunlight to observe its condition, and then rate it.

[0061] It should be noted that the pressure value is displayed by a pressure sensor sensing the pressure and transmitting the specific value to the display panel. Specifically, a pressure sensor is a sensor capable of sensing pressure. It measures pressure by converting the pressure from an object into an electrical signal. Generally, a pressure sensor consists of three parts: a sensing element, a signal processing circuit, and an output interface. The sensing element is the core of the pressure sensor, and its working principle mainly includes piezoresistive effect, capacitive effect, and inductive effect. Among these, the piezoresistive effect is the most commonly used. Its principle is based on the change in resistance of a metal thin film or semiconductor material with pressure. When pressure is applied by an object, the resistance of the sensing element changes accordingly, thereby generating an electrical signal. The signal processing circuit mainly amplifies, filters, and linearizes the electrical signal output by the sensing element to ensure that the output signal is stable, reliable, and accurate. The output interface outputs the processed signal to the display screen of an external device. Common output methods include analog signal output and digital signal output. In summary, the working principle of a pressure sensor is to convert the pressure applied by an object into an electrical signal, process it through the signal processing circuit, and finally output it to an external device.

[0062] In a preferred embodiment of the present invention, in S1, the bottom of the combing component is uniformly provided with a plurality of teeth; in S3, the detection component is a woven plain woolen fabric.

[0063] In a preferred embodiment of the present invention, in S5, the rating is divided into no aurora, slight aurora, and severe aurora based on the color depth and variation.

[0064] It should be noted that the rating standards for the aurora produced after fabric friction are usually based on the depth and degree of color change. The rating standards are as follows: Severe aurora: bright color, distinct change, rich color, obvious gloss effect; Slight aurora: lighter color, less distinct change, relatively simple color, slightly weaker gloss effect; No aurora: very light color, very weak change, simple color, almost invisible gloss effect.

[0065] Based on the preferred embodiments of the present invention described above, those skilled in the art can make various changes and modifications without departing from the inventive concept. The technical scope of this invention is not limited to the contents of the specification, but must be determined according to the scope of the claims.
