AI Technical Summary

Technical Problem

In existing embroidery machines, long, strip-shaped limiting bars tend to protrude from the main body of the equipment, resulting in poor operational safety and unstable limiting effect.

Method used

Each set of line-lifting rods corresponds to a set of limiting components, including a locking rod and a reset component. The edge of the locking rod is equipped with a hook that cooperates with the limiting groove of the line-lifting rod. The reset component ensures that the locking rod flips over, achieving individual limiting and avoiding the collision risk of long limiting strips.

Benefits of technology

It significantly improves the safety of equipment operation and the reliability of limit switches, avoids limit switch deviation, and ensures the stability and accuracy of the line take-up lever.
