Abstract

The invention provides a thread cutting mechanism and a sewing machine with the same. The thread cutting mechanism is used for cutting a bottom thread and an upper thread of the sewing machine, and comprises first and second cutter pieces and a fixing seat. The first cutter piece is provided with a thread hooking part, the first cutter piece is rotatably arranged around a preset axis so as to hook the bottom thread and the upper thread through the thread hooking part, and the thread hooking part is provided with a first cutting surface which is horizontally arranged; at least part of the second cutter piece is located in the side of the first cutter piece, the second cutter piece is provided with a horizontally-arranged second cutting face, and in the process that the first cutter piece rotates in the direction close to the second cutter piece, the first cutting face and the second cutting face make contact with each other so as to cut the bottom line and the upper line; and the second cutter piece is mounted on the fixing seat, and the position of the second cutter piece relative to the fixing seat is adjustably arranged. Thus, the problem of low production efficiency of the sewing machine in the prior art is solved.

Description

technical field [0001] The invention relates to the field of mechanical design, in particular to a thread trimming mechanism and a sewing machine with the same. Background technique [0002] At present, during the working process of the sewing machine, the lengths of the bottom thread and the upper thread on the sewing material after cutting the sewing thread are all determined by the distance from the pinhole to the cutting edge. [0003] In the existing thread trimming mechanism, the edge of the thread trimming is far away from the hole of the needle plate, resulting in too long residues of the bottom thread and upper thread on the sewing material after thread trimming, which requires manual secondary thread trimming, resulting in workers' labor Increased strength reduces the productivity of the sewing machine. Contents of the invention [0004] The main purpose of the present invention is to provide a thread trimming mechanism and a sewing machine with the same, so as ...
