Description

Technical Field

[0001] This invention belongs to the field of fabric inspection technology, and in particular relates to a multifunctional fabric defect marking device. Background Technology

[0002] With the textile industry's ever-increasing demands for product quality, the detection and marking of defects on fabric surfaces has become a crucial step in the production process. Currently, the industry widely uses fully automated inspection equipment for online or offline defect identification and marking of fabrics. These systems typically rely on high-resolution image acquisition and machine learning algorithms to achieve rapid identification and location of common defects.

[0003] Existing defect marking devices often suffer from performance degradation when inspecting fabrics, significantly influenced by the fabric's physical condition. On one hand, fabrics are prone to wrinkles and deformation during production and handling, leading to shadows or texture distortion during image acquisition, resulting in false or missed detections. On the other hand, dust and fiber debris, common in textile environments, adhere to the fabric surface, interfering with the accuracy of image sensors. Furthermore, fabrics easily generate static electricity due to friction, attracting dust and potentially causing fabric vibration or adhesion to sensors, further affecting detection stability. Therefore, multiple pre-treatment steps are required before defect detection, including eliminating wrinkles with spreading rollers or steam ironing, removing surface dust using negative pressure vacuuming or airflow cleaning systems, and reducing static electricity buildup using ionizers. These pre-treatment steps increase equipment complexity, floor space, and energy consumption.

[0004] To address these issues, we provide a multifunctional fabric defect marking device. Summary of the Invention

The bottom of the reinforcing rod is fixedly connected to the collection box 592. A sealing plate is fixedly connected to one side of the collection box 592 via bolts.

[0040] The working principle of this invention is as follows: the connecting pipe 65 is connected to an external antistatic agent storage device. The fabric body 4 passes through the space between two conveying rollers 2 on one side, then through the bottom of the dust-adhesive roller 54, between the tension roller 52 and the first cleaning roller 53, between the two guide rollers 3 and the two atomizing spray plates 63, and exits from the space between two conveying rollers 2 on the other side. The servo motor drives the conveying rollers 2 to rotate. The conveying rollers 2 are driven in pairs by the synchronous pulley, synchronous belt and drive gear to convey the fabric body 4. During the conveying process, the fabric body 4 drives the tension roller 52 to rotate counterclockwise. The tension roller 52 eliminates wrinkles in the fabric body 4. The first cleaning roller 53 is driven to rotate counterclockwise by the synchronous pulley and synchronous belt to clean the dust at the bottom of the fabric body 4. At the same time, the fabric body 4 drives the dust-adhesive roller 54 to rotate counterclockwise. The first linkage gear 56 drives the second linkage gear 583 to rotate clockwise to clean the dust-adhesive roller 54.

[0041] The drive motor 672 drives the second threaded rod 673 to rotate, which in turn drives the piston plate 675 to move via the second threaded sleeve rod 674. This causes the antistatic agent in the storage tank 61 to be squeezed out from the atomizing spray plate 63 through the conduit 62 and the diverter pipe 64, thus atomizing and eliminating static electricity on both sides of the fabric body 4. When the second threaded sleeve rod 674 moves, it drives the toothed plate 6610 to move via the connecting frame 676. This drives the drive rod 661 to rotate via the third linkage gear 662, which in turn drives the rotating rod 596 and the fan 597 to rotate via the synchronous pulley and synchronous belt. The rotation of the fan 597 generates negative pressure, which draws dust into the collection box 592 through the dust collection hood 591. The dust can be removed by periodically opening the sealing plate. When the storage tank 61 is emptied, the one-way valve at the connecting pipe 65 is opened, causing the drive motor 672 to reverse and draw in the antistatic agent in a measured amount.

[0042] When the tension of the tension roller 52 needs to be adjusted, the second cylinder 668 is activated to move the limiting plate 669, releasing the limit on the fourth linkage gear 666. The first cylinder 664 is activated to insert the limiting rod 665 into the limiting groove 667. The drive rod 661 rotates, causing the fourth linkage gear 666 to rotate. The second linkage gear 583 drives the first threaded rod 581 to rotate. The first threaded sleeve rod 582 and the bracket 51 move downward as a whole, thereby adjusting the tension. When the antistatic agent is quantitatively inhaled, the tension roller can be adjusted to move upward.

[0043] After undergoing pretreatment such as tensioning, wrinkle removal, dust removal, and static electricity removal, the fabric enters the inspection area. The industrial inspection camera 10 acquires images of the fabric and detects the location of defects using image recognition technology. The inspection results are transmitted to the control system, which drives the electric drive unit 8 to move the marker 9 along the guide rail 7 to accurately mark the defects.

[0044] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
