The function of camera detection device used on the warp knitting machine is to detect and monitor the fabric being produced. It uses a camera or cameras to capture images of the fabric as it is being knitted. The device then analyzes these images to identify and detect any defects or irregularities in the fabric. The camera detection device can detect various types of defects such as holes, dropped stitches, missing loops, or any other abnormalities in the fabric. It can also identify issues with the yarn tension or yarn breakages during the knitting process. Once a defect or irregularity is detected, the camera detection device sends a signal to the machine's control system. The control system can then take appropriate actions to rectify the issue, such as stopping the machine, adjusting the yarn tension, or initiating repairs. By using a camera detection device, manufacturers can ensure the production of high-quality fabrics with minimal defects. It helps in reducing waste, improving productivity, and maintaining consistent fabric quality.
