Description

Technical Field

[0001] This invention relates to the field of fabric inspection equipment technology, specifically an inspection device for air-jet looms. Background Technology

[0002] Air-jet looms are commonly used weaving equipment. To ensure the quality of fabric woven by air-jet looms, it is often necessary to inspect the fabric, which requires the use of fabric inspection equipment. Patent application number CN202210777807.0 discloses a double-sided defect inspection machine for textile fabrics. By using two image acquisition devices in conjunction with a first transmission roller, it can simultaneously detect and warn of defects on both sides of the fabric, and can verify the defect detection results in real time, thereby improving the efficiency of fabric inspection. This reduces the labor intensity of workers. By setting a backlight strip, the contrast of the backlight strip can improve the quality of fabric defect detection by the image acquisition instrument. At the same time, the image acquisition instrument can detect the parallelism between the colored light strip on the backlight strip and the edge of the fabric in real time, which can detect whether the fabric has shifted in real time, thus improving the stability of fabric transmission. The invention patent with patent application number CN202411794661.6 discloses a fabric detection device and detection method for linen and cotton yarn-dyed fabric production. The extension component is equipped with multiple sets of photosensors and wiping frames. The wiping frames are sensitive to the photosensors. The surface of the photosensitive element is wiped to prevent water mist from affecting its detection accuracy. The washing component of this invention automatically rubs and washes the fabric while controlling the rubbing force to restore the fabric to its state after long-term use. The washing component also automatically dries the fabric, improving washing efficiency. The photometric component of this invention includes multiple irradiators and cameras. The working angles of the irradiators and cameras can be adjusted to expand the detection and irradiation range of the fabric, improving the detection accuracy of various fabric properties. According to the disclosed technical solution, existing fabric inspection equipment has several drawbacks. First, during inspection, debris and impurities attached to the fabric and the inspection plate can easily interfere with the test results, compromising the reliability of the inspection. Second, the absorption and filtration of debris and impurities is often slow and difficult to remove quickly, thus hindering the absorption effect. Third, it cannot accurately mark defects on the fabric, often requiring machine downtime, which is detrimental to the production efficiency of the loom. Summary of the Invention

The bottom of the shovel plate is connected to the inner wall of the inner groove by a spring. The top of the shovel plate is stuck on the bottom of the rotating roller.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0015] 1. When using this detection device for an air-jet loom, the motor is turned on, and the motor pushes the yarn sleeve through the lead screw, causing the two suction ports to move away from each other, providing a sufficient feeding channel for the fabric to pass through the machine housing. Then, the motor is turned on in reverse, moving the two suction ports closer to the two sides of the fabric. The fan generates suction in the air box through the air duct, drawing debris and impurities attached to the fabric into the inside of the air box through the suction ports. These are then filtered out by the filter screen. The air duct blows the filtered dust-free air into the inside of the machine housing, effectively cooling the laser generator, laser receiver one, and laser receiver two. The cooled air then exits through the outlet. The air is blown out from the other side of the box, creating a dust-free environment on the left side of the box. This effectively prevents debris and impurities from the production workshop from entering the inside of the box. The laser generator emits a laser, which is reflected by the fabric and received by the laser receiver two. The laser that passes through the fabric is received by the laser receiver one, and the light signal is converted into an electrical signal for data processing and display. When the light signal generated on the fabric is abnormal, it indicates that there is a quality defect in that area of ​​the fabric. This effectively removes debris and impurities from the fabric surface and the inside of the box, preventing debris and impurities from interfering with the fabric's detection structure and ensuring the reliability of the detection results.

[0016] 2. In use, the detection device for this air-jet loom blows the film on the side plate to the left, allowing air and inhaled debris and impurities to enter the inner side of the insertion box through the opening in the side plate. The debris and impurities are filtered out by the filter screen. As the amount of debris and impurities increases, the ventilation speed of the filter screen decreases. By pushing the locking pin, the insertion box is separated from the outer side of the machine casing. Then, the insertion box is pulled out from the inside of the machine casing. A spring pushes the scraper, scraping off the filtered debris and impurities on the filter screen and collecting them inside the insertion box. The film on the side plate can only be pushed open in one direction, thus preventing debris from returning to the inside of the air box. After removing the insert box and cleaning away debris, push the scraper and spring together to the inside of the slot and lock them with the stop pin. Then insert the insert box into the slot until it is fully inserted. The guide block pushes the stop pin, and the spring pushes the scraper to the left and locks it in place on the right side of the slot. This prevents debris from being scraped to the bottom of the slot, which would hinder the cleaning process. The top of the insert box is locked to the chassis with a latch, facilitating the cleaning of debris and ensuring effective absorption of debris from the fabric. At the same time, the cleaning process does not affect the testing process, making it more convenient to use.

[0017] 3. When the detection device for the air-jet loom detects a defect in the fabric, the electromagnet is activated. The electromagnet attracts the support block through magnetic force, compresses the second spring, and drives the support rod upward. The support rod drives the pressure roller upward to the bottom of the rotating roller. The rotating roller is driven by the fabric, and the rotating roller drives the pressure roller to rotate. The pressure roller drives the piston upward through the pull cable. The piston moves upward to the squeeze button, and the button opens the nozzle. The distance the fabric moves from the bottom of the laser generator to the top of the nozzle matches the distance the pressure roller drives the piston upward to the button. The nozzle sprays the fluorescent agent in the box onto the defect area on the fabric, thus marking the defect. This allows for the treatment of defects in subsequent processing without stopping the air-jet loom, ensuring the working efficiency of the air-jet loom. If fluorescent agent adheres to the rotating roller, the scraper, under the elastic force of the fourth spring, scrapes the fluorescent agent adhering to the rotating roller onto the inside of the receiving hopper, preventing the fluorescent agent from adhering to the normal area of ​​the fabric.

The debris and impurities are filtered out by the filter screen 17. As the amount of debris and impurities increases, the ventilation speed of the filter screen 17 decreases. By pushing the stop pin 22, the insertion box 14 is separated from the outer side of the casing 1, and then the insertion box 14 is pulled out from the inside of the casing 1. The spring 20 pushes the scraper 19 to scrape off the filtered debris and impurities on the filter screen 17. The debris is collected inside the insert box 14.

The air duct 12 is connected to one side of the partition plate 6 through the air box 11. Slots 18 are provided on the inner side of the air box 11 and the top of the casing 1. In use, the motor 8 is turned on, and the motor 8 is connected to the lead screw 10. Pushing the wire sleeve 9 moves the two suction ports 7 away from each other, providing ample feeding channels for the fabric to pass through the housing 1. Then, turning on the motor 8 in the opposite direction moves the two suction ports 7 closer to the fabric. The fan 13 generates suction on the air box 11 through the air duct 12, drawing debris and impurities adhering to the fabric into the inside of the air box 11 through the suction ports 7. These are then filtered out by the filter screen 17. The air duct 12 blows the filtered dust-free air into the inside of the housing 1, effectively cooling the laser generator 3, laser receiver 1 4, and laser receiver 2 5. The air is then blown out from the other side of the housing 1 through the outlet 24. The system creates a dust-free environment on the left side of the housing 1, effectively preventing debris and impurities from the production workshop from entering the inside of the housing 1. The laser generator 3 emits a laser, which is reflected by the fabric and received by the laser receiver 2 5. The laser that passes through the fabric is received by the laser receiver 1 4, and the light signal is converted into an electrical signal for data processing and display. When the light signal generated on the fabric is abnormal, it indicates that there is a quality defect in that area of ​​the fabric. The system can effectively remove debris and impurities from the surface of the fabric and the inside of the housing 1, preventing debris and impurities from interfering with the fabric detection structure and ensuring the reliability of the detection results.

[0030] In this embodiment, the two ends of the rotating roller 23 are mounted on the inner wall of the housing 1 via bearings. The outlet 24 is located on the other side of the housing 1 and is evenly distributed on the housing 1. The housing 25 is bolted to the inner wall of the bottom of the housing 1. The nozzle 26 is bolted to the top of the housing 25. The inner side of the housing 25 is filled with fluorescent agent. The bottom of the nozzle 26 is connected to the bottom of the housing 25.

The bottom of the shovel plate 38 is connected to the inner wall of the inner groove via a spring 39, and the top of the shovel plate 38 is engaged at the bottom of the rotating roller 23. When a defect in the fabric is detected, an electromagnet 29 is activated. The electromagnet 29 attracts the support block 27 through magnetic force, compresses the spring 30, and drives the support rod 28 to move upward. The support rod 28 drives the pressure roller 31 to move upward to the bottom of the rotating roller 23. The rotating roller 23 is driven by the fabric, and the rotating roller 23 drives the pressure roller 31 to rotate. The pressure roller 31 drives the piston 33 to move upward via a pull wire 35. The piston 33 moves upward to the bottom of the extrusion... Press button 36 to open nozzle 26. The distance the fabric moves from the bottom of laser generator 3 to the top of nozzle 26 matches the distance the pressure roller 31 drives the piston 33 to move upward to button 36 via pull line 35. Nozzle 26 sprays fluorescent agent from box 25 onto defective areas of fabric, thus marking defects and enabling subsequent processing without stopping the air-jet loom, ensuring its efficiency. If fluorescent agent adheres to roller 23, scraper plate 38, under the elastic force of spring 39, scrapes the fluorescent agent onto roller 23 to the inside of receiving hopper 37, preventing fluorescent agent from adhering to normal areas of fabric.

[0031] The detection device for the air-jet loom provides power to all electrical equipment via an external power supply. During operation, motor 8 is turned on, and motor 9 pushes the yarn sleeve 9 via the lead screw 10, causing the two suction ports 7 to move away from each other, providing ample feeding channels for the fabric to pass through the machine housing 1. Then, motor 8 is turned on in reverse, moving the two suction ports 7 closer to the fabric. Fan 13 generates suction on the air box 11 through the air duct 12, drawing debris and impurities adhering to the fabric into the inside of the air box 11 through the suction ports 7. These are then filtered out by the filter screen 17. The air duct 12 blows the filtered, dust-free air into the inside of the machine housing 1, effectively cooling the laser generator 3, laser receiver 1 4, and laser receiver 2 5. The cooled air then exits through the outlet. 24 is blown out from the other side of the casing 1, forming a dust-free environment on the left side of the casing 1, effectively preventing debris and impurities from the production workshop from entering the inside of the casing 1. The laser generator 3 emits a laser, and the laser reflected by the fabric is received by the laser receiver 2 5. The laser passing through the fabric is received by the laser receiver 1 4, and the light signal is converted into an electrical signal for data processing and display. When the light signal generated on the fabric is abnormal, it indicates that there is a quality defect in that area of ​​the fabric. It can effectively remove debris and impurities from the surface of the fabric and the inside of the casing 1, preventing debris and impurities from interfering with the fabric detection structure and ensuring the reliability of the detection results. Air and sucked-in debris and impurities enter the insertion box 14 through the opening of the side plate 15. Inside the air box 11, debris and impurities are filtered out by the filter screen 17. As the amount of debris and impurities increases, the ventilation speed of the filter screen 17 decreases. By pushing the locking pin 22, the insertion box 14 is separated from the outer side of the casing 1. The insertion box 14 is then pulled out from the inside of the casing 1. The spring 20 pushes the scraper 19 to scrape off the debris and impurities filtered on the filter screen 17 and collect them inside the insertion box 14. The film 16 on the side plate 15 can only be pushed open in one direction, thus preventing debris from returning to the inside of the air box 11. After the insertion box 14 is pulled out and the debris and impurities are cleaned off, the scraper 19 is compressed by the spring 20 and pushed into the inside of the slot, and locked by the stop pin 21. Then the insertion box 14 is inserted into the inside of the slot 18 until the insertion box 14 is fully inserted into the slot 18. Inside, the guide block pushes the stop pin 21, and the spring 20 pushes the scraper 19 to the left until it is locked in place on the right side of the slot 18, preventing debris from being scraped to the bottom of the slot 18 and hindering the cleaning process. The top of the insertion box 14 is locked to the housing 1 by the latch 22, facilitating the cleaning of debris and impurities and ensuring the absorption effect of debris and impurities on the fabric. At the same time, the cleaning process does not affect the detection work, making it more convenient to use. When a defect in the fabric is detected, the electromagnet 29 is activated. The electromagnet 29 attracts the support block 27 through magnetic force, compresses the spring 30, and drives the support rod 28 to move upward. The support rod 28 drives the pressure roller 31 to move upward to the bottom of the rotating roller 23. The rotating roller 23 is driven by the fabric, and the rotating roller 23 drives the pressure roller 31 to rotate.The pressure roller 31 drives the piston 33 upward via the pull cable 35. The piston 33 moves upward to the pressing button 36, which opens the nozzle 26. The distance the fabric travels from the bottom of the laser generator 3 to the top of the nozzle 26 matches the distance the pressure roller 31, driven by the pull cable 35, moves the piston 33 upward to the button 36. The nozzle 26 sprays the fluorescent agent from the housing 25 onto the defective areas of the fabric, thus marking the defects. This allows for subsequent processing of the defects without stopping the air-jet loom, ensuring its efficiency. If fluorescent agent adheres to the roller 23, the scraper plate 38, under the elastic force of the spring 39, scrapes the fluorescent agent off the roller 23 and onto the inside of the receiving hopper 37, preventing the fluorescent agent from adhering to the normal areas of the fabric.
