Description

Technical Field

[0001] The invention relates to the technical field of cloth detection, and in particular to a cloth detection device and a detection method for producing linen-cotton yarn-dyed cloth. Background Art

[0002] Post-production testing of fabrics is an important part of ensuring the quality and suitability of fabrics, which is mainly reflected in quality control, compliance with standards, improving customer satisfaction, reducing returns and complaints, improving production efficiency, and promoting product innovation. Through testing, defects that may occur in the production process, such as uneven fibers, color differences, insufficient tear strength, etc., can be identified and eliminated. Washability testing can evaluate the strength, color stability and appearance changes of fabrics after multiple washes to ensure the durability of fabrics in actual use. Transmittance testing ensures the performance of fabrics under different lighting conditions, especially in applications such as curtains and sunshades. Transmittance directly affects the use effect and living comfort. At the same time, materials that are too translucent may cause privacy issues, so testing can ensure that the product meets the needs of users.

[0038] A method for detecting fabric used in the production of linen-cotton yarn-dyed fabrics comprises the following steps:

[0039] S1, placing the cloth 103 on the bracket 101, and driving the clamping mechanism to clamp the cloth 103 and lay it flat on the bracket 101.

[0040] S2. Drive the cleaning disc 208 to scrub the surface of the cloth 103.

[0041] S3, after cleaning is completed, the drying head 204 and the scraper 205 are started to dry the cloth 103.

[0042] S4, driving the washing component 2 to reset, and starting the light measuring component 3 to detect the cloth 103.

[0043] S5, starting the camera 305 to detect surface defects of the cloth 103.

[0044] S6 , start the irradiator 312 to irradiate the cloth 103 with light, and start the photoreceptor 113 to detect the amount of light passing through the cloth 103 .

[0045] S7. Drive the adjustment mechanism to adjust the angle between the camera 305 and the illuminator 312 to improve the accuracy of the detection of the cloth 103.

[0046] Working principle: During operation, a group of fabrics 103 to be inspected is placed on the bracket 101, one end of the fabric 103 is passed under the roller 102 and placed between the clamping block 106 and the sliding block 107, the clamping block 106 is driven to slide on the sliding block 107, the clamping block 106 and the sliding block 107 clamp the fabric 103, and the two groups of sliding blocks 107 are driven to slide on the bracket 101, the sliding block 107 gradually moves away from the roller 102, the sliding block 107 drives the fabric 103 to move away from the roller 102 synchronously, and the roller 102 is driven to rotate at the same time, and the roller 102 is driven to rotate, and the fabric 103 is pushed to slide on the bracket 101 when the roller 102 rotates, so as to prevent the fabric 103 from sliding on the bracket 101. Wrinkles, when the sliding block 107 drives the cloth 103 to move, it will drive the cloth 103 to pass through the multiple groups of support plates 105 and support plates 2 108. When the cloth 103 is laid flat on the bracket 101, the support plate 105 is driven to slide on the support frame 104, and the support plate 105 is close to the support plate 2 108. At this time, the support plate 105 clamps the cloth 103, and the support plate 105 and the support plate 2 108 control the cloth 103 to be pressed on the surface of the bracket 101 to prevent the cloth 103 from shifting during the washing process, and complete the laying of the cloth 103. In the initial state, the multiple groups of closing covers 112 close the bracket 101, and the closing cover 112 is located above the photoreceptor 113.

[0047] When the cloth 103 needs to be washed, the washing rack 206 is driven to slide on the sliding rack 202, and the washing rack 206 drives the cleaning disc 208 to descend and gradually approach the cloth 103. When the cleaning disc 208 is in contact with the cloth 103, the multiple groups of spray columns 212 are driven to rotate, and the angles of the spray columns 212 are adjusted so that the spraying positions of the spray columns 212 are aligned with the contact positions of the cleaning disc 208 and the cloth 103. The spray columns 212 are driven to work, and the spray columns 212 spray water and cleaning liquid onto the cloth 103. The cleaning disc 208 is driven to rotate, and the cleaning disc 208 scrubs the cloth 103. The sliding rack 202 is driven to slide on the fixed rack 201, and the sliding rack 202 drives the cleaning disc 208 to move, thereby increasing the cleaning range of the cloth 103. The cam 210 is driven to rotate, and the cam 210 pushes the extension rod 211 moves with the second sliding frame 207. Since the second sliding frame 207 is provided with a spring 209, the second sliding frame 207 slides back and forth on the washing frame 206 through the deformation recovery force of the spring 209. The second sliding frame 207 drives the cleaning plate 208 to slide back and forth, thereby improving the scrubbing effect of the cleaning plate 208, and increasing the pressure between the cleaning plate 208 and the cloth 103 when driving the washing frame 206 to continue to descend. At this time, the cleaning plate 208 will cause greater damage to the cloth 103 when scrubbing the cloth 103, and restore the state of the cloth 103 after long-term use and multiple washings, thereby improving the accuracy of various performance detections of the cloth 103, and the waste water generated when washing the cloth 103 flows out through the two groups of leakage grooves 109 and the multiple groups of leakage holes 111 on the bracket 101, so as to avoid the accumulation of waste water on the bracket 101.

[0048] After washing the cloth 103, the drying rack 203 is driven to slide on the sliding rack 202, and the drying rack 203 drives the drying head 204 and the scraper 205 to approach the cloth 103, and the scraper 205 is driven to rotate on the drying rack 203 so that the scraper 205 fits the cloth 103, and the multiple groups of drying heads 204 are driven to work, and the drying heads 204 blow hot air to the cloth 103 for drying. At the same time, the sliding rack 202 is driven to slide on the fixed rack 201, and the sliding rack 202 drives the drying head 204 to move, scrape the surface of the cloth 103, and push the cleaned sewage to move while scraping off the stains.

[0049] After the drying of the cloth 103 is completed, the sliding frame 202 is driven to slide on the fixed frame 201, so that the sliding frame 202 is located at the end of the bracket 101 away from the roller 102, the mobile frame 301 is driven to slide on the bracket 101, and the mobile frame 301 drives the camera 305 and the illuminator 312 to reach the detection position, and the lifting frame 302 is driven to slide on the mobile frame 301, and the lifting frame 302 drives the camera 305 and the illuminator 312 to approach the cloth 103, and the camera 305 detects defects on the surface of the cloth 103 to determine the washability of the cloth 103. The irradiator 312 is started to irradiate the cloth 103 with light, and the support plate 105 and the support plate 108 are driven to slide on the support frame 104, so that the support plate 105 and the support plate 108 drive the cloth 103 to rise, so that there is a gap between the cloth 103 and the bracket 101, which is convenient for light to penetrate, and the closing cover 112 is driven to slide on the detection box 110, and the closing cover 112 releases the blocking of the photoreceptor 113, and at the same time drives the wiping frame 114 to move, and the wiping frame 114 wipes the surface of the photoreceptor 113 to prevent the surface of the photoreceptor 113 from being damaged. The presence of water mist on the surface affects the detection result. The photoreceptor 113 receives the light passing through the cloth 103. The light transmittance of the cloth 103 after washing is judged according to the amount of light received by the cloth 103. In order to improve the detection accuracy of the light transmittance of the cloth 103, it is necessary to irradiate the cloth 103 from multiple angles. When the angles of the irradiator 312 and the camera 305 are adjusted, the lifting plate 304 is driven to slide on the support rod 307, and the lifting plate 304 drives the limit slot 306 to move. Since the limit ball 311 slides in the limit slot 306, the limit slot 306 drives the limit ball 311 rotates along the axis of the second rotating column 309. When the second rotating column 309 rotates, it drives the placement plate 310 to rotate. The placement plate 310 drives the illuminator 312 and the camera 305 to rotate, so as to adjust the positions of the illuminator 312 and the placement plate 310. When the rotating column 1 308 is driven to rotate, the rotating column 1 308 drives the second rotating column 309 to rotate along the axis of the rotating column 1 308. The rotating column 2 309 drives the placement plate 310 to rotate along the axis of the rotating column 1 308, so as to adjust the angle of the illuminator 312, so as to ensure that the cloth 103 can be irradiated at all angles.
