Description

Technical Field

[0001] The invention relates to the technical field of fabric detection, in particular to a device and a method for testing the rubbing color fastness of dark cotton corduroy fabric. Background Art

[0002] Dark cotton corduroy fabric usually refers to a velvet fabric woven with cotton fibers. The surface is similar to velvet and has a rich texture and touch. Dark refers to the darker color of this fabric, usually a dark color such as dark blue, dark gray, dark purple, etc. This fabric is often used to make winter clothing, household items, etc., because its velvet texture can provide a certain warmth effect;

[0003] In combination with the above content, it should be explained that: during the rubbing color fastness test of traditional dark cotton corduroy fabric, the test fabric and rubbing color fastness test object need to be constantly replaced according to the progress. The overall replacement process is cumbersome and affects the test efficiency. In addition, there is a tendency for the test fabric and rubbing color fastness test object to be stored in a mess. At the same time, the traditional fabric testing method is single, resulting in different fabrics being interfered by texture, chroma and other related factors, resulting in large fluctuations in test accuracy and efficiency.

[0004] In view of the above technical defects, a solution is now proposed. Summary of the invention

[0005] The purpose of the present invention is to provide a dark cotton corduroy fabric rubbing color fastness test device, which collects data during use, obtains the material edge clamping floating value and the rubbing surface relaxation ratio, and comprehensively supervises and analyzes the use process of the detection device before and during material replacement, that is, compares and analyzes the collected data with the preset storage data, obtains relevant rating signals, and controls relevant components to perform compensatory operations accordingly, which can not only constitute the linkage and mutual matching of the system and the mechanical structure, avoid the feeding anomaly of the fabric during automatic material replacement, and reduce the influence of material fixation-related factors on the rubbing color fastness test results, but also utilize the multiple magnetic suction conversion connections and pneumatic adsorption connections between the material replacement mechanism and the material clamping friction dynamic inspection mechanism, combined with the ball joint rolling adjustment dynamic structure, to achieve adaptive and quick adjustment of the fabric with fabric center offset or fixation anomaly after feeding, improve the overall detection efficiency and accuracy, so as to solve the technical defects proposed by the background technology.

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a dark cotton corduroy fabric friction color fastness test device, comprising a chassis, an electric guide rail is arranged on the top periphery of the chassis, and a material changing mechanism is arranged on the top of the electric guide rail, lifting bases are symmetrically arranged at both ends of the chassis, and an adjusting beam and a control panel are arranged on the lifting base, a material clamping friction dynamic inspection mechanism is arranged in the middle of the adjusting beam, and the material clamping friction dynamic inspection mechanism includes an exhaust fan and a bottom shell, and a metal ring plate is sleeved on the outer periphery of the bottom shell;

[0011] Furthermore, a special-shaped rod is arranged on the top of the driving seat, a magnetic bracket connected to the arc-shaped material rack is arranged on the top of the special-shaped rod, and a plurality of groups of sliding rods are arranged on the bottom.

[0012] Furthermore, a magnetic pressure groove is provided in the center depression of the top of the rotating disk, and a metal sheet is provided on the top of the magnetic pressure groove, a guide column embedded in the side of the rotating disk is provided at the bottom of the pressure ring, and a groove is provided in the depression of the top edge of the rotating disk.

[0013] Furthermore, the control panel is internally provided with a processor, a data acquisition module, a state analysis module and a component execution module;

[0014] The data acquisition module is used to collect the material edge clamping floating value LJz located at the top periphery of the bottom shell and the rubbing surface relaxation ratio CMz located at the bottom of the bottom shell during use of the test device, and send the material edge clamping floating value LJz and the rubbing surface relaxation ratio CMz to the state analysis module via the processor;

[0015] After receiving the uniform floating value LJz of the material edge clamp and the rubbing surface relaxation ratio CMz, the state analysis module immediately analyzes the adaptability of the material clamp of the experimental device. The specific analysis process is as follows: the uniform floating value LJz of the material edge clamp and the rubbing surface relaxation ratio CMz of the experimental device within the time threshold are obtained, the material clamp risk coefficient JLi is obtained through the formula, and the preset material clamp risk coefficient YLi stored and entered is retrieved from the processor for comparison and analysis with the material clamp risk coefficient JLi; if the material clamp risk coefficient JLi ≥ the preset material clamp risk coefficient YLi, it is determined that there is an abnormal risk in the use of the experimental device within the time threshold, and an adjustment signal is generated. The generated signal is sent to the component execution module via the processor. After receiving the adjustment signal, the component execution module immediately controls the exhaust fan to work; if the material clamp risk coefficient JLi is less than the preset material clamp risk coefficient YLi, no signal is generated.

[0016] The present invention also provides a working method of a dark cotton corduroy fabric rubbing color fastness test device, comprising the following steps:

[0017] Step 1: Place the dark cotton wick fabrics to be tested on the curved material rack in turn, and lay the rubbing color fastness test object flat on the top of the rotating disk;

[0018] Step 2: The lifting base drives the adjustment beam to slide vertically along the Z axis through the connecting piece, and drives the distance adjustment between the clamping friction dynamic inspection mechanism and the rotating disk. A pushing cylinder connected to the inner sliding frame is embedded in the inner wall of the adjustment beam. The pushing cylinder drives the inner sliding frame to slide longitudinally along the Y axis on the adjustment beam, and the clamping friction dynamic inspection mechanism adjusts the contact area between the bottom shell and the rubbing color fastness test object on the rotating disk;

[0019] Step 3: In the first detection method, the driving motor drives the reciprocating threaded rod to rotate through the transmission member, and the reciprocating threaded rod drives the connecting rod to move axially along the guide groove through the slider, and the connecting rod drives the bottom shell and the fixed fabric to move synchronously through the exhaust fan, and then reciprocates and contacts with the local area of ​​the rubbing color fastness test object;

[0020] Step 4: In the second detection method, the servo motor drives the rotating disk to rotate through the transmission part, and the rotating disk drives the color fastness detection object to rotate and contact the fixed fabric. The fabric performs circular rotational friction on the surface of the color fastness detection object, forming a standard circular friction fading track on the surface of the color fastness detection object;

[0021] Step 5: The third detection method is to drive the drive motor and the servo motor to run synchronously, respectively driving the fabric to move back and forth along a certain trajectory, and the rubbing color fastness test object to rotate at a certain uniform speed, so that the fabric forms a curved arc friction fading trajectory on the surface of the rubbing color fastness test object;

[0022] Step 6: The lifting base and the inner sliding frame adjust the material clamping friction and the dynamic inspection mechanism moves to the edge of the rotating disk. The material changing mechanism slides along the electric guide rail through the driving seat and approaches the bottom of the bottom shell. The lifting base drives the bottom shell to slide down and abut against the central groove of the magnetic bracket. The electromagnetic force of the magnetic ring groove disappears when the electromagnetic force is disconnected, and the magnetic bracket is energized to generate magnetic force. The metal ring plate falls under the magnetic attraction, and the extrusion and clamping of the fabric are released. The exhaust fan is connected to the suction groove through the pipe fitting to adsorb the fabric that has lost its restraint on the bottom shell, and move the blank area on the arc material rack to the bottom of the bottom shell. The inspected fabric is placed in the blank area of ​​the arc material rack, the bottom shell is reset and slid up, and the arc material rack is adjusted again to move the remaining fabric to be inspected to the bottom of the bottom shell. The exhaust fan generates suction when it runs, and the fabric is adsorbed and then slides up. The magnetic bracket moves to the bottom of the bottom shell, and the bottom shell is inserted into the central groove of the magnetic bracket again. The metal ring plate slides up under the influence of magnetic attraction, and the edge of the fabric is straightened along the outer wall of the bottom shell and embedded between the magnetic ring groove and the metal ring plate for fixed clamping.

[0023] The beneficial effects of the present invention are:

[0024] 1. The present invention collects data of the detection device during use, obtains the material edge clamping floating value and the rubbing surface relaxation ratio, and comprehensively supervises and analyzes the use process of the detection device before and during material change, that is, compares and analyzes the collected data with the preset storage data, obtains relevant rating signals, and controls relevant components to perform compensatory operations accordingly, so as to form a linkage and mutual matching between the system and the mechanical structure, avoid the abnormal feeding of the fabric during the automatic material change, and reduce the influence of the material fixation-related factors on the rubbing color fastness test results, and can also use the multiple magnetic suction conversion connections and pneumatic adsorption connections between the material change mechanism and the material clamping friction dynamic inspection mechanism, combined with the ball joint rolling adjustment dynamic structure, to achieve adaptive and quick adjustment of the fabric with fabric center deviation or fixation abnormality after feeding, thereby improving the overall detection efficiency and accuracy;

[0025] 2. The present invention uses a material-clamping friction dynamic testing mechanism in conjunction with a rotating disk to form multiple methods for testing the color fastness of fabrics by rubbing, effectively improving the demand for different methods of testing the color fastness of fabrics by rubbing, and improving the utilization rate of the blank area on the surface of the object to be tested for color fastness by rubbing, thereby reducing the loss of testing materials.

DETAILED DESCRIPTION

[0035] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0036] Example 1: Please refer to Figure 1 - Figure 7 As shown, this embodiment is a dark cotton corduroy fabric friction color fastness test device, comprising a chassis 1, an electric guide rail 101 is arranged on the top periphery of the chassis 1, and a material changing mechanism 4 is arranged on the top of the electric guide rail 101, lifting bases 102 are symmetrically arranged at both ends of the chassis 1, and an adjusting beam 5 and a control panel 6 are arranged on the lifting base 102, and a material clamping friction dynamic inspection mechanism 3 is arranged in the middle of the adjusting beam 5;

[0037] The material clamping friction dynamic inspection mechanism 3 includes an exhaust fan 302 and a bottom shell 310, and a metal ring plate 307 is sleeved on the outer periphery of the bottom shell 310; the material changing mechanism 4 includes a driving seat 401 and an arc-shaped material rack 404, a rotating disk 2 is arranged at the top center of the bottom plate 1, a servo motor 206 is arranged at the bottom of the rotating disk 2, and a pressure ring 202 is arranged on the outer periphery of the top of the rotating disk 2;

[0038] The control panel 6 is internally provided with a processor, a data acquisition module, a state analysis module and a component execution module; the data acquisition module is used to collect the material edge clamping floating value LJz at the top periphery of the bottom shell 310 and the rubbing surface relaxation ratio CMz at the bottom of the bottom shell 310 during the use of the test device, and send the material edge clamping floating value LJz and the rubbing surface relaxation ratio CMz to the state analysis module via the processor; 10 minutes during the use of the detection device is set as the time threshold;

[0039] It should be noted that: the material edge clamping floating value LJz is expressed as the amount of fabric coverage area between the outer inner wall of the magnetic ring groove 304 and the metal ring plate 307 obtained within the time threshold, and the value of the material edge clamping floating value LJz reflects whether the fabric is installed skewed between the magnetic ring groove 304 and the metal ring plate 307, and the larger the value of the material edge clamping floating value LJz, the more it indicates that there is uneven fabric clamping between the magnetic ring groove 304 and the metal ring plate 307 within the time threshold, and the rubbing surface relaxation ratio CMz is expressed as the tightness of the fabric part covered by the magnetic ring groove 304 and the metal ring plate 307 on the surface of the bottom shell 310 after being clamped and limited by the magnetic ring groove 304 and the metal ring plate 307. In addition, the material edge clamping floating value LJz is collected by the object scanning sensor installed on the inner walls on both sides of the magnetic ring groove 304, and the rubbing surface relaxation ratio CMz is collected by multiple groups of pressure sensors installed on the outer edge of the bottom of the shell 310 and the industrial camera installed on the inner wall of the lifting base 102;

[0040] After receiving the material edge clamp uniform floating value LJz and the rubbing surface relaxation ratio CMz, the state analysis module immediately analyzes the material clamp adaptability of the experimental device. The specific analysis process is as follows:

[0041] Obtain the material edge clamping floating value LJz and the surface relaxation ratio CMz of the experimental device within the time threshold, and use the formula The material clamp risk coefficient JLi is obtained, where a and b are the proportional coefficients of the material edge clamp uniform floating value LJz and the rubbing surface relaxation ratio CMz respectively, a>b>0, JLi is expressed as the material clamp risk coefficient, and the preset material clamp risk coefficient YLi stored and entered is retrieved from the processor for comparison and analysis with the material clamp risk coefficient JLi;

[0042] If the material clamp risk coefficient JLi ≥ the preset material clamp risk coefficient YLi, it is determined that there is an abnormal risk in the use of the experimental device within the time threshold, and an adjustment signal is generated. The generated signal is sent to the component execution module through the processor. After receiving the adjustment signal, the component execution module immediately controls the exhaust fan 302 to work;

[0043] The lifting base 102 and the inner sliding frame 501 drive the bottom shell 310 to move close to the edge of the rotating disk 2. At the same time, the material changing mechanism 4 drives the magnetic bracket 403 to move to the bottom of the bottom shell 310. The magnetic ring groove 304 is powered off, and the magnetic bracket 403 is powered on. The metal ring plate 307 falls to release the clamping of the fabric. The bottom shell 310 is driven by the lifting base 102 to slide up slightly by 10 mm. In this state, the fabric and the bottom shell 310 remain in a loose state.

[0044] A magnetic arc plate is provided at the bottom of the telescopic cylinder 305 and is magnetically connected to the roller ball 306. The telescopic cylinder 305 mobilizes the roller ball 306 to slide down, and the magnetic arc plate is powered off to contact the magnetic attraction and lock the roller ball 306, so that the roller ball 306 is stuck at the bottom of the ball groove 312, and the bottom of the roller ball 306 extends along the notch at the bottom of the ball groove 312 to contact the inner wall of the fabric. At the same time, after the roller ball 306 slides down, the periphery contacts the output end of the micro motor 309, and the micro motor 309 is driven to rotate by the rotary cylinder 308, so that the micro motor 309 is connected to the outer periphery of the roller shaft and is adjusted according to the parameters of the material edge clamping floating value LJz generated by the detection after the fabric is installed, so that the center of the outer periphery of the fabric is calibrated with the center of the bottom shell 310, and the edges of the fabric are evenly distributed in the magnetic ring groove 304;

[0045] If the risk coefficient of the tilting material clamp JLi is less than the preset risk coefficient of the tilting material clamp YLi, no signal is generated.

[0046] Embodiment 2: This embodiment is a working method of a dark cotton corduroy fabric friction color fastness test device, comprising cutting the dark cotton corduroy fabric to be tested into the shape required by the test device, and placing them on the arc-shaped material rack 404 in sequence, cutting the test rubbing color fastness detection object into a disc shape, taking out the metal sheet 204, spreading the rubbing color fastness detection object on the top of the rotating disk 2, and putting the metal sheet 204 back on the magnetic suction pressure groove 205, taking out the pressure ring 202, smoothing the edge of the rubbing color fastness detection object, and using an external tool to press the edge of the rubbing color fastness detection object into the groove 201, and inserting the pressure ring 202 back into the groove 201 along the guide column 203;

[0049] A special-shaped rod 402 is arranged on the top of the driving seat 401, a magnetic bracket 403 connected to the arc-shaped material rack 404 is arranged on the top of the special-shaped rod 402, and a plurality of sliding rods 405 are arranged on the bottom. A magnetic pressure groove 205 is arranged in a concave center at the top of the rotating disk 2, and a metal sheet 204 is arranged on the top of the magnetic pressure groove 205. A guide column 203 embedded in the side of the rotating disk 2 is arranged at the bottom of the pressure ring 202, and a groove 201 is arranged in a concave groove at the top edge of the rotating disk 2.

[0050] The device is started through the control panel 6, and the magnetic suction pressure groove 205 is electrified to absorb the metal sheet 204, so that the rubbing color fastness test object is compacted and fixed along the center. The lifting base 102 drives the adjusting crossbeam 5 to slide vertically along the Z axis through the connecting piece, and drives the distance adjustment between the clamping material friction dynamic testing mechanism 3 and the rotating disk 2. A pushing cylinder connected to the inner sliding frame 501 is embedded in the inner wall of the adjusting crossbeam 5. The pushing cylinder drives the inner sliding frame 501 to slide longitudinally along the Y axis on the adjusting crossbeam 5, and adjusts the contact area between the bottom shell 310 of the clamping material friction dynamic testing mechanism 3 and the rubbing color fastness test object on the rotating disk 2;

[0051] In the first detection method, the driving motor 502 drives the reciprocating threaded rod 503 to rotate through the transmission member, and the reciprocating threaded rod 503 drives the connecting rod 301 to move axially along the guide groove 504 through the slider 303, and the connecting rod 301 drives the bottom shell 310 and the fixed fabric to move synchronously through the exhaust fan 302, and then reciprocates and contacts and rubs with the local area of ​​the rubbing color fastness detection object, which is used to detect the color fading and wear resistance of the fabric; in the second detection method, the servo motor 206 drives the rotating disk 2 to rotate through the transmission member, and the rotating disk 2 drives the rubbing color fastness detection object to rotate and contact the fixed fabric, so that the fabric is forced to perform circular rotational friction on the surface of the rubbing color fastness detection object, and a standard circular friction fading trajectory is formed on the surface of the rubbing color fastness detection object;

[0052] The third detection method is to drive the motor 502 and the servo motor 206 to run synchronously, respectively driving the fabric to move back and forth along a certain trajectory, and the rubbing color fastness detection object to rotate at a certain uniform speed, so that the fabric forms a curved arc rubbing color fading trajectory on the surface of the rubbing color fastness detection object, effectively improving the full utilization of the detection blank area of ​​the rubbing color fastness detection object;

The magnetic bracket 403 is moved to the bottom of the bottom shell 310, and the bottom shell 310 is inserted into the center groove of the magnetic bracket 403 again. The magnetic bracket 403 is powered off, and the magnetic ring groove 304 is powered on. The metal ring plate 307 slides up under the influence of magnetism, and the edge of the fabric is straightened along the outer wall of the bottom shell 310 and embedded between the magnetic ring groove 304 and the metal ring plate 307 for fixed clamping.

[0056] Combining Example 1 and Example 2, it can be seen that it can not only constitute the linkage and mutual matching of the system and the mechanical structure, avoid the feeding anomaly of the fabric during the automatic material change, and reduce the influence of the material fixation-related factors on the rubbing color fastness test results, but also utilize the multiple magnetic conversion connections and pneumatic adsorption connections between the material changing mechanism 4 and the material clamping friction dynamic inspection mechanism 3, combined with the ball joint rolling adjustment dynamic structure, to achieve adaptive and quick adjustment of the fabric with fabric center offset or fixation abnormality after feeding, thereby improving the overall detection efficiency and accuracy.
