AI Technical Summary

Technical Problem

Existing sewing equipment requires frequent changes or adjustments when processing different fabrics, which is inefficient, increases maintenance costs, and makes it difficult to guarantee the processing quality of the fabrics.

Method used

The system employs a thread-lifting mechanism, which controls the reciprocating rotation of the drive shaft via a drive device. This allows for flexible adjustment of the position of the first thread-passing hole by adjusting the position of the thread-lifting hook, thus matching the thread quantity requirement of each stitch in real time and achieving a dynamic balance between the thread supply and the required thread quantity.

Benefits of technology

Without requiring equipment adjustments, it optimizes sewing results, significantly improves the adaptability and stability of the sewing process to fabrics, and ensures high-quality sewing results.
