Abstract

The invention relates to a thread adjuster. The thread adjuster comprises a thread adjusting seat. Multiple yarn selecting assemblies and yarn cutting and releasing assemblies are arranged on the thread adjusting seat. Each yarn selecting assembly is composed of a swing arm, a yarn selecting connecting piece, a carriage saddle, and a cutter bar arranged on the carriage saddle, wherein one end of the swing arm is hinged to the thread adjusting seat, one end of the yarn selecting connecting piece is connected with the other end of the swing arm, and the other end of the yarn selecting connecting piece is connected with the carriage saddle. Each yarn cutting and releasing assembly is composed of a yarn cutting and releasing connecting piece, a linkage block, a yarn cutting piece and a yarn releasing piece, wherein the middle of the linkage block is hinged to the thread adjusting seat, one end of the yarn cutting and releasing connecting piece is connected with one end of the linkage block, and one end of the yarn cutting piece and one end of the yarn releasing piece are connected to the ends of the linkage block respectively. The yarn cutting pieces and the yarn releasing pieces are matched with the cutter bars to cut and release yarn. The yarn cutting and releasing connecting pieces in all the yarn cutting and releasing assemblies are connected through linkage bars, and the linkage bars are located in the swing tracks of the swing arms. The accuracy of yarn cutting is guaranteed.

Description

Yarn changing device

Technical field

The present invention relates to the technical field of knitting machine, the yarn changing device particularly in pointer loom.
