AI Technical Summary

Technical Problem

During operation, traditional sewing machine shuttles are prone to noise due to friction and vibration between components, and accelerate wear of components and reduce service life.

Method used

Inject polymer polyethylene material into the guide rail hook head to form plastic parts, and the installation groove is embedded on the periphery of the guide rail hook head to achieve shock absorption, buffering and noise reduction effects.

Benefits of technology

It effectively reduces the friction and vibration of the shuttle during operation, reduces noise, and improves the stability and service life of the sewing machine.

Abstract

The utility model discloses a sewing machine rotating shuttle with plastic damping, which comprises an outer shuttle, an inner shuttle is rotatably arranged on the inner side of the outer shuttle, a moon ring and a shuttle skin which are used for guiding sewing threads are mounted on the outer side of the outer shuttle, a guide rail is arranged on the outer side of the inner shuttle, and a combined hook head is arranged at the end of the guide rail. The combined hook head is composed of a plastic part and a guide rail hook line head part, the guide rail hook line head part is located in the middle of the plastic part, the guide rail hook line head part and the inner shuttle are of an integrated structure, a mounting groove matched with the guide rail hook line head part in shape is formed in the inner side of the plastic part, and the guide rail hook line head part is embedded into the inner side of the mounting groove in a clamped mode. The plastic part is embedded in the thread hooking head of the guide rail, so that friction and vibration between the guide rails in the operation process of the rotating shuttle can be effectively reduced, noise of the rotating shuttle of the sewing machine can be reduced on the premise that the service life of the rotating shuttle is not affected, and stability is improved.
