[0001] The present invention relates to the field of detection technology, and particularly to a detecting device and a detecting method for the surface texture of a flushable spunlace fabric. Background Art

[0002] The flushable spunlace fabric is an environment-friendly non-woven material made by the spunlace process, and has the characteristics of being degradable and flushable, and is commonly used in fields such as wet wipes and medical supplies. Plain patterns, concave-convex patterns, mesh patterns, etc. are provided on the surface of the spunlace fabric, and the width, depth and distribution of the surface texture will directly affect the hand feeling, strength, liquid permeability and flushability of the product. In the industry, the quality of the surface texture is judged by visually observing the difference from the standard sample to qualitatively estimate whether the texture is qualified. This method has large human operation errors and randomness, the detection process takes a long time, the accuracy is low, the efficiency is low, and the index cannot be quantified.

[0003] A patent for a novel living paper texture detection device with the publication number of CN109884075A in the prior art is composed of at least a detection device, a positioning device, an integrated protection device and a transmission analysis device. The detection device and the positioning device are arranged in the integrated protection device, and the positioning device can be freely put in or taken out. After the sample is placed on the positioning device, the detection device will detect the sample, and the detection device will input the detection data into the transmission analysis device to count and calculate the thickness and quantity of the texture of the biological paper; the detection device includes a high-definition industrial camera and an automatic induction light source; the high-definition industrial camera is arranged at the center of the top of the integrated protection device, and the automatic induction light source is arranged on the lower side of the high-definition industrial camera.

[0004] The above detection device detects the paper surface texture by taking pictures with a high-definition industrial camera, which has the characteristics of high detection accuracy and good stability. However, due to the limitations of industrial camera photography, the above detection device can only detect the width of the texture and cannot detect the depth of the texture, and the detection has great limitations. Summary of the Invention

[0005] The present invention provides a detecting device and a detecting method for the surface texture of a flushable spunlace fabric, which solve the problems in the prior art that the texture detection is not comprehensive and the depth and width of the texture cannot be detected simultaneously.

[0006] The technical solution of the present invention is realized as follows: A detecting device for the surface texture of a water-soluble spunlace fabric, comprising a frame. An installation component one for driving the fabric to be measured to move and an installation component two for driving the test paper to move are provided on the frame. A probe component is movably connected to the frame. When the detecting device is in use, the head of the probe component contacts the fabric to be measured, and the tail of the probe component contacts the test paper. When the probe component contacts the surface of the fabric to be measured, as the installation component one drives the fabric to be measured to move, the probe component vibrates along with the surface texture of the fabric, and this vibration is recorded on the test paper through the tail of the probe component. The test data of the texture is displayed on the test paper. By analyzing the texture data on the test paper, the width and depth of the surface texture of the fabric to be measured can be obtained, ensuring the comprehensiveness of the surface texture detection of the fabric.

[0007] The installation component one includes a first pulley and a second pulley rotatably arranged on the frame. A first belt is connected between the first pulley and the second pulley, and the fabric to be measured is detachably arranged on the first belt. The installation component two includes a third pulley and a fourth pulley rotatably arranged on the frame. A second belt is connected between the third pulley and the fourth pulley, and the test paper is detachably arranged on the second belt. A driving mechanism is provided on the frame, and the driving mechanism drives the first belt and the second belt to move synchronously through a transmission mechanism. The probe component records the texture data of the surface of the fabric to be measured on the test paper in a one-to-one ratio, digitalizes the texture on the fabric surface that is not easy to measure, and plays a certain role in standardizing the texture of the fabric.

[0008] The first pulley and the second pulley are arranged on the horizontal panel of the frame, and the first belt is wound around the first pulley and the second pulley. The third pulley and the fourth pulley are arranged on the vertical panel of the frame, and the second belt is wound around the third pulley and the fourth pulley.

[0009] The transmission mechanism includes a transmission rod. One end of the transmission rod is connected to the third pulley through a second bevel gear set, the middle of the transmission rod is connected to the first pulley through a first bevel gear set, and the other end of the transmission rod is connected to the driving mechanism. The transmission ratios of both the first bevel gear set and the second bevel gear set are 1, so that the rotation speeds of the first pulley and the third pulley are equal, thereby ensuring the synchronous movement of the fabric to be measured and the test paper.

[0010] The driving mechanism includes a driving motor. The output end of the driving motor is connected to the transmission rod, and the input end of the driving motor is connected to a control system. A test switch, a reset switch, and a power switch are provided on the frame, and the test switch, the reset switch, and the power switch are all connected to the control system. The power switch controls the power on or off of the driving motor, the test switch controls the forward rotation of the driving motor, and the reset switch controls the reverse rotation of the driving motor.

[0011] The probe assembly includes a support frame and a detection probe. The detection probe is movably connected to the support frame. The lower end of the detection probe corresponds to the position of the cloth to be measured, and a recording pen is connected to the upper end of the detection probe. The recording pen corresponds to the position of the test paper. When the cloth to be measured moves relative to the detection probe, the detection probe vibrates along with the surface of the cloth to be measured, and the pattern is recorded on the test paper by the recording pen.

[0012] A counterweight block is detachably connected to the detection probe. By installing counterweight blocks of different weights, the contact pressure between the detection probe and the cloth to be measured is adjusted, so that the detection device is suitable for detecting the patterns of the cloth to be measured under different conditions.

[0013] The detection probe is connected to the support frame through a connecting rod. One end of the connecting rod is fixedly connected to the detection probe, and the other end of the connecting rod is hinged to the support frame. When the detection probe contacts the surface of the cloth to be measured, the pattern on the cloth to be measured pushes up the detection probe, causing the detection probe to swing slightly up and down; in addition, the hinged connecting rod facilitates the separation of the detection probe from the first installation component, thereby facilitating the installation of the cloth to be measured.

[0014] The connecting rod is a telescopic rod. By adjusting the length of the connecting rod, the relative position between the detection probe and the cloth to be measured can be adjusted, thereby facilitating multiple detections of the cloth to be measured, obtaining multiple detection results, and improving the accuracy of the detection results.

[0015] A spring clip is provided at the upper end of the detection probe, and the recording pen is connected to the detection probe through the spring clip. The spring clip fixes the recording pen at the upper end of the detection probe, ensuring the stable connection between the recording pen and the detection probe during the detection process. At the same time, the position of the recording pen on the detection probe can be adjusted to make the recording pen contact or separate from the test paper on the second installation component, facilitating the installation of the test paper.

Start the drive motor, and the drive motor drives the first belt and the second belt to move synchronously through the transmission mechanism; S6, the detection probe and the cloth to be tested generate relative movement, the detection probe contacts the grain on the surface of the cloth to be tested and generates vibration; the vibration of the detection probe drives the recording pen to move on the test paper, and the recording pen records the vibration generated by the detection probe on the test paper; the test paper displays the grain line of the grain on the surface of the cloth to be tested, and the grain line includes fluctuating line segments and stable line segments; S7, water needle pattern width detection, intercept n peaks or troughs from the wave line segment, measure the total width m of the n peaks or troughs, and divide the length m of the pattern line segment by the number of peaks or troughs n to obtain the water needle pattern width W; water needle pattern depth detection, measure the height values ​​of n peaks and troughs, calculate the average value of the heights of n peaks and the average value of the depths of n troughs, and subtract the average value of the peak heights from the average value of the trough depths to obtain the water needle pattern depth D; S8, embossing width detection, measuring the width of the stable line segment on the test paper to obtain the embossing width W1; embossing depth detection, calculating the average value of the height of each peak in the fluctuating line segment on the test paper, and subtracting the height of the stable line segment from the average value of the peak height to obtain the embossing depth D1; S9, replace the test paper, reset the cloth to be tested when the detection probe is separated from the cloth to be tested, adjust the length of the connecting rod, change the relative position of the detection probe and the cloth to be tested, repeat steps S5 to S8, and obtain another set of grain width detection results and grain depth detection results; determine the grade of the cloth to be tested by detecting the grain width and grain depth.

[0017] The beneficial effects of the present invention are as follows: 1. When the detection probe is in contact with the surface of the cloth to be tested, the detection probe and the cloth to be tested are relatively moved, and the recording pen on the detection probe draws the texture of the surface of the cloth to be tested on the test paper, so as to realize the data of the texture of the cloth surface, and then the width and depth of the texture of the cloth surface can be obtained by calculating and analyzing the texture data on the test paper, so as to ensure the comprehensiveness of the texture detection; 2. The relative position between the detection probe and the fabric to be tested is adjusted by adjusting the length of the connecting rod, so that the detection device can perform multiple tests on the same fabric to be tested, thereby improving the accuracy of the texture detection results; 3.

[0021] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0022] Embodiment 1, as Figure 1 、 Figure 2As shown in the figure, a detecting device for the surface texture of a water-soluble spunlace fabric includes a frame 1. On the frame 1, there is a first mounting component 2 for driving the fabric to be tested 7 to move and a second mounting component 3 for driving the test paper 6 to move. A probe component is movably connected to the frame 1. When the detecting device is in use, the head of the probe component contacts the fabric to be tested 7, and the tail of the probe component contacts the test paper 6. Specifically, on the frame 1, there are a horizontal panel and a vertical panel perpendicular to each other. The first mounting component 2 is arranged along the front-back direction of the frame 1 on the horizontal panel of the frame 1, that is, the y-axis direction of the frame 1; the second mounting component 3 is arranged along the left-right direction of the frame 1 on the vertical panel of the frame 1, that is, the x-axis direction of the frame 1, and the moving direction of the probe component is the up-down direction of the frame 1, that is, the z-axis direction of the frame 1; when the first mounting component 2 drives the fabric to be tested 7 to move along the y-axis direction, the texture on the surface of the fabric to be tested 7 will cause the probe component to vibrate up and down. At the same time, since the second mounting component 3 drives the test paper 6 to move along the x-axis direction, the probe component can record the texture on the surface of the fabric to be tested 7 on the test paper 6 in a vibrating manner, realizing the digitization of the surface texture of the fabric. By calculating and analyzing the texture data on the test paper 6, the width and depth of the surface texture of the fabric can be obtained, ensuring the comprehensiveness of texture detection.

[0023] Furthermore, the first mounting component 2 includes a first pulley 21 and a second pulley 23 rotatably arranged on the frame 1. A first belt 22 is connected between the first pulley 21 and the second pulley 23. The fabric to be tested 7 is detachably arranged on the first belt 22; the second mounting component 3 includes a third pulley 31 and a fourth pulley 33 rotatably arranged on the frame 1. A second belt 32 is connected between the third pulley 31 and the fourth pulley 33. The test paper 6 is detachably arranged on the second belt 32. A driving mechanism is provided on the frame 1, and the driving mechanism drives the first belt 22 and the second belt 32 to move synchronously through a transmission mechanism. Specifically, the fabric to be tested 7 is connected to the first belt 22 through double-sided tape, and the test paper 6 is connected to the second belt 32 through double-sided tape, ensuring the installation stability of the fabric to be tested 7 on the first belt 22 and the installation stability of the test paper 6 on the second belt 32.

[0024] Embodiment 2, different from Embodiment 1, for a detecting device for the surface texture of a water-soluble spunlace fabric, elastic bandages are respectively arranged on the outer sides of the first belt 22 and the second belt 32. When installing the fabric to be tested 7 or the test paper 6, the elastic bandages press and fix the two ends of the fabric to be tested 7 or the test paper 6, thereby realizing the installation and fixation of the fabric to be tested 7 or the test paper 6.

[0025] Embodiment 3, on the basis of Embodiment 1, for a detecting device for the surface texture of a water-soluble spunlace fabric, as Figure 4As shown in the figure, the transmission mechanism includes a transmission rod 8. One end of the transmission rod 8 is connected to the third pulley 31 through a second bevel gear set 83, the middle of the transmission rod 8 is connected to the first pulley 21 through a first bevel gear set 82, and the other end of the transmission rod 8 is connected to a driving mechanism. The transmission ratios of both the first bevel gear set 82 and the second bevel gear set 83 are 1, so that the rotational speeds of the first pulley 21 and the third pulley 31 are equal, thereby ensuring the synchronous movement of the cloth to be measured 7 and the test paper 6. Furthermore, the pattern can be recorded on the test paper 6 at a ratio of 1:1, facilitating subsequent detection of the pattern width and depth.

[0026] Furthermore, as Figure 5 shown in the figure, the driving mechanism includes a driving motor 9. The output end of the driving motor 9 is connected to the transmission rod 8, and the input end of the driving motor 9 is connected to a control system 92. A test switch 12, a reset switch 13, and a power switch 14 are provided on the frame 1. The test switch 12, the reset switch 13, and the power switch 14 are all connected to the control system 92. The power switch 14 controls the power-on or power-off of the driving motor 9, the test switch 12 controls the forward rotation of the driving motor 9, and the reset switch 13 controls the reverse rotation of the driving motor 9. A driving gear 91 is connected to the output end of the driving motor 9, and a driven gear 81 is connected to the end of the transmission shaft 8. The driving gear 91 meshes with the driven gear 81. In addition, a display screen 11 is further provided on the frame 1, and the display screen 11 is used to display the moving speed and moving direction of the test paper 6 and the cloth to be measured 7.

[0027] Embodiment 4, based on Embodiment 1, a device for detecting the pattern on the surface of a disposable spunlace fabric. The probe assembly includes a support frame 5 and a detection probe 4. The detection probe 4 is movably connected to the support frame 5. The lower end of the detection probe 4 corresponds to the position of the cloth to be measured 7, and a recording pen 41 is connected to the upper end of the detection probe 4. The recording pen 41 corresponds to the position of the test paper 6. In this embodiment, the detection probe 4 is connected to the support frame 5 through an elastic rod. When the detection probe 4 contacts the surface of the cloth to be measured 7, the pattern on the surface of the cloth to be measured 7 will push the detection probe 4 to move up and down. At this time, the elastic rod deforms, and the recording pen 41 on the detection probe 4 can record the shape of the pattern on the test paper 6.

[0028] Furthermore, a spring clip is provided at the upper end of the detection probe 4, and the recording pen 41 is connected to the detection probe 4 through the spring clip. The spring clip fixes the recording pen 41 at the upper end of the detection probe 4, ensuring the stable connection between the recording pen 41 and the detection probe 4 during the detection process. At the same time, the position of the recording pen 41 on the detection probe 4 can be adjusted to make the recording pen 41 contact or separate from the test paper 6 on the second mounting assembly 3, facilitating the installation of the test paper 6.

[0029] Furthermore, a counterweight block is detachably connected to the detection probe 4. As Figure 3As shown in the figure, in this embodiment, there are 5 weight mounting holes provided on the detection probe 4. The weight mounting holes are threaded holes, and the weight nuts are threadedly connected to the weight threaded holes. Different weights of weight blocks are threadedly connected to the weight bolts. By installing the weight bolts, the contact pressure between the detection probe 4 and the cloth to be measured 7 is adjusted, so that the detection device is applicable to the texture detection of the cloth to be measured 7 in different situations. Specifically, since the raw materials used for the flushable cloth and the internal fiber entanglement structures are mostly different, the support forces presented by the fibers inside the texture are also different. Weighing the detection probe 4 and unifying the contact pressure can limitedly formulate detection standards and ensure the unity of raw material detection in this index.

[0030] Different weights will yield different results when testing the same sample. By adjusting the weight and setting the preconditions of the weight, the depth of the texture can be specifically defined. In this embodiment, a weight of 100 cN is set on the detection probe 4, and the measured texture depth is 0.3 mm. Among them, 100 cN is the precondition for testing the texture depth, that is, under the weight of 100 cN, the texture depth is 0.3 mm.

[0031] Embodiment 5, on the basis of Embodiment 4, a flushable spunlace cloth surface texture detection device, the detection probe 4 is connected to the support frame 5 through a connecting rod 51. One end of the connecting rod 51 is fixedly connected to the detection probe 4, and the other end of the connecting rod 51 is hinged to the support frame 5. When the detection probe 4 contacts the surface of the cloth to be measured 7, the texture on the cloth to be measured 7 lifts the detection probe 4, causing the detection probe 4 to swing slightly up and down. In addition, the hinged connection of the connecting rod 51 facilitates the separation of the detection probe 4 from the first mounting component 2, and thus facilitates the installation of the cloth to be measured 7.

[0032] Furthermore, the connecting rod 51 is a telescopic rod. By adjusting the length of the connecting rod 51, the relative position between the detection probe 4 and the cloth to be measured 7 in the left-right direction can be adjusted, so as to facilitate multiple detections of the cloth to be measured 7 and obtain multiple detection results, improving the accuracy of the detection results.

[0033] Embodiment 6, on the basis of Embodiment 5, a detection method for a flushable spunlace cloth surface texture detection device, the cloth to be measured 7 is a flushable spunlace cloth, as Figure 6 shown, water needle patterns and embossed patterns are provided on the surface of the cloth to be measured 7. The detection of the width and depth of the water needle patterns and the width and depth of the embossed patterns includes the following steps: S1, sample preparation, cut the cloth to be measured 7 and the test paper 6; specifically, cut the cloth to be measured 7 and the test paper 6 with a length of 12 cm and a width of 4 cm; S2. Install the cloth to be measured 7 on the first belt 22 of the first installation component 2, and install the test paper 6 on the second belt 32 of the second installation component 3. Specifically, use double-sided tape to install and fix the cloth to be measured 7 and the test paper 6. The cloth to be measured 7 is arranged along the front-back direction of the frame 1, and the test paper 6 is arranged along the left-right direction of the frame 1. S3. Install a counterweight on the detection probe 4. Adjust the number of installation of the counterweight bolts on the detection probe 4 to adjust the contact pressure between the detection probe 4 and the cloth to be measured 7. Since the raw materials used for the scourable cloth and the internal fiber entanglement structures are mostly different, the supporting forces presented by the fibers inside the texture are also different. By performing counterweight and unifying the contact pressure, the detection standard can be limitedly formulated to ensure the unity of the raw material detection in this index. S4. Install a recording pen 41 on the upper part of the detection probe 4. The recording pen 41 contacts the test paper 6, and the lower end of the detection probe 4 contacts the cloth to be measured 7. The recording pen 41 is connected to the detection probe 4 by a spring clip, and the spring clip ensures the installation stability of the recording pen 41 on the detection probe 4. The writing diameter of the tip of the recording pen 41 ≤ 0.05 mm. S5. Start the drive motor 9. The drive motor 9 drives the first belt 22 and the second belt 32 to move synchronously through the transmission mechanism. S6. Relative movement is generated between the detection probe 4 and the cloth to be measured 7. The detection probe 4 contacts the texture on the surface of the cloth to be measured 7 and generates vibration. The vibration of the detection probe 4 drives the recording pen 41 to move on the test paper 6, and the recording pen 41 records the vibration generated by the detection probe 4 on the test paper 6. The texture lines of the surface of the cloth to be measured 7 are displayed on the test paper 6, and the texture lines include fluctuating line segments and stable line segments. Specifically, as Figure 7 shown, the cloth to be measured 7 moves in the front-back direction, and the test paper 6 moves in the left-right direction. The moving speeds of the cloth to be measured 7 and the test paper 6 are equal. Among them, the fluctuating line segment is the shape of the water needle texture, and the stable line segment is the shape of the embossed texture. S7. Detection of the width of the water needle texture. Intercept n wave peaks or wave valleys from the fluctuating line segment, measure the total width m of the n wave peaks or wave valleys, and divide the length m of the texture line segment by the number n of wave peaks or wave valleys to obtain the width W of the water needle texture. Detection of the depth of the water needle texture. Measure the height values of the n wave peaks and wave valleys, calculate the average value of the heights of the n wave peaks and the average value of the depths of the n wave valleys, and subtract the average value of the depths of the wave valleys from the average value of the heights of the wave peaks to obtain the depth D of the water needle texture. S8. Detection of the width of the embossed texture. Measure the width of the stable line segment on the test paper 6 to obtain the embossed width W1. Detection of the depth of the embossed texture. Calculate the average value of the heights of the n wave peaks in the fluctuating line segment on the test paper 6, and subtract the height value of the stable line segment from the average value of the heights of the wave peaks to obtain the embossed depth D1. S9. Replace the test paper 6, reset the cloth to be tested 7 when the detection probe 4 is separated from the cloth to be tested 7, adjust the length of the connecting rod 51, change the relative position between the detection probe 4 and the cloth to be tested 7, and repeat steps S5 - S8 to obtain another set of detection results for the width and depth of the texture; determine the grade of the cloth to be tested based on the detected width and depth of the texture.

[0034] Grade evaluation of the cloth to be tested 7: The wider the water needle texture width, the rougher the surface of the cloth to be tested 7; the smaller the water needle texture width, the finer the surface of the cloth to be tested 7. Specifically, when W ≤ 0.4 mm, the texture on the surface of the cloth to be tested 7 is a fine water needle texture; when 0.4 mm < W ≤ 0.7 mm, the texture on the surface of the cloth to be tested 7 is a medium water needle texture; when W > 0.7 mm, the texture on the surface of the cloth to be tested 7 is a wide water needle texture.

[0035] The deeper the water needle texture depth, the clearer the water needle texture, the higher the texture, and the greater the frictional force on the cloth surface during wiping; the shallower the water needle texture depth, the more blurred the water needle texture, the lower the texture, and the lower the frictional force on the cloth surface during wiping. When the ratio of the texture depth D to the thickness of the cloth to be tested 7 is less than 0.5, the cloth surface texture is a shallow water needle texture; when the ratio of the texture depth D to the thickness of the cloth to be tested 7 is greater than 0.5, the cloth surface texture is a deep water needle texture.

[0036] The width of the embossed pattern directly affects the embossed area. The larger the width of the embossed pattern, the larger the embossed area, and the less linting on the surface of the cloth to be tested 7; the smaller the width of the embossed pattern, the smaller the embossed area, and the more linting on the surface of the cloth to be tested 7. In addition, the width of the embossed pattern affects the visual sense. For embossed patterns of the same shape, the larger the width of the embossed pattern, the more bloated the visual manifestation of the embossed pattern; the smaller the width of the embossed pattern, the more delicate the visual manifestation of the embossed pattern. Although the embossed patterns are of the same shape, the visual manifestations are different, which is not conducive to the unified application of the cloth surface texture for products with flushable cloth as the raw material. After detecting the width W1 of the embossed pattern, it is necessary to compare it with the set width W0 of the embossed pattern. When the width deviation at the same position of different textures > 2% * W0, the visual deviation of the texture is defined as large; when the width deviation at the same position of different textures ≤ 2% * W0, the visual deviation of the texture is defined as small.

[0037] The deeper the embossed pattern depth, the clearer the embossed pattern, and the higher the recognition and stronger the three - dimensional sense of the cloth surface texture. Classify the embossed pattern by comparing the embossed pattern thickness. The value of the embossed pattern thickness ratio I = (thickness of the cloth to be tested - embossed pattern depth D1) / thickness of the cloth to be tested * 100%. When I ≥ 70%, the embossed pattern is a shallow pattern; when 40% ≤ I < 70%, the embossed pattern is a medium pattern; when I < 40%, the embossed pattern is a deep pattern.

[0038] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
