Hook ring swing seat device for sewing machine and adjusting method thereof

Abstract

The invention relates to a hook ring swing seat device for a sewing machine and an adjusting method thereof. A hook ring swing seat is arranged and a rotary shaft installed on the sewing machine. A transverse adjusting part, a shuttle needle adjusting part and a needle-guiding device adjusting part are arranged on the hook ring swing seat. When benchmarks of the shuttle needle, the needle-guiding device and a machine needle are set and adjusted on the hook ring swing seat, the transverse adjusting part is utilized for adjusting and correcting the transverse distance between the shuttle need and the machine needle located at a lower starting point and the needle-guiding device is utilized for adjusting and correcting interference amount of the needle-guiding device to the machine needle. Ultimately, the shuttle needle adjusting part is used for adjusting and correcting the pointed end of the shuttle needle, and a concave part of the machine needle. Therefore, the hook ring swing seat device for the sewing machine and the adjusting method thereof have following beneficial effects: by utilization of separate design of adjusting structures, benchmarks of the shuttle needle, the needle-guiding device and the machine needle are finished setting, adjusting and correcting; no adjusted and corrected benchmarks do not vary; and real benefits such as improvement in convenience for adjustment and correction are achieved.
