I. Project Background

In the operation of textile machinery and automated sewing equipment, needle threading is a key process affecting sewing quality and efficiency. To break through the bottleneck of quality and efficiency improvement, automated threading technology has become an inevitable choice for industry development.

As automated threading requires millisecond-level precise control, traditional monitoring equipment is limited by sampling rate and resolution, making it difficult to fully capture the dynamic interaction data between the thread and the needle. With high-resolution imaging and high-frame-rate sampling technology, Shenshi Intelligent high-speed cameras provide reliable image data support for core steps of threading: thread guiding, needle hole positioning, and thread pulling through.

II. Case Analysis

The Shenshi Intelligent SH3-103 high-speed camera captures needle threading in real time at a high frame rate of 3000 FPS. With a resolution of 1280 × 1024 pixels, it fully records the needle movement trajectory, needle hole positioning accuracy, and thread end guiding profile.

By frame-by-frame analysis of the footage recorded by the high-speed camera, engineers can promptly identify mechanical defects such as thread breakage, needle hole blockage, and machine vibration, thereby optimizing equipment processes, improving the stability of sewing machines, and effectively ensuring sewing surface quality.

In addition, Shenshi Intelligent high-speed cameras can be linked with machinery via external trigger signals. Combined with the center recording mode using equipment alarm signals, they realize real-time monitoring of equipment operation and accurately capture the entire process of failures.

III. Recommended Shenshi Intelligent High-Speed Cameras

The application of Shenshi Intelligent high-speed cameras in textile machinery needle threading strongly supports quality control, process improvement, and equipment performance optimization. By capturing high-speed motion details during threading, it helps detect and solve issues hard to notice with traditional methods, driving the advancement of textile machinery and automated sewing equipment.
