Abstract

The invention provides a thread trimming mechanism and a sewing machine with the thread trimming mechanism. The thread trimming mechanism is used for cutting off a sewing thread of a sewing material located on a needle plate assembly, and a needle hole for the sewing thread to pass through is formed in the needle plate assembly. The thread trimming mechanism comprises a fixed knife and a movable knife, wherein at least a part of a cutting edge of the fixed knife is arranged opposite to the needle hole; the movable knife is movably arranged, so that the movable knife has a thread drawing position and a thread cutting position; the movable knife is movably arranged along the moving direction of the sewing material, so that after the movable knife pulls the sewing thread to move from the thread drawing position to the thread cutting position, the sewing thread is cut off under the action of the movable knife and the fixed knife. The thread trimming mechanism provided by the invention solves the problem that in the prior art, after threads are trimmed by the thread trimming mechanism, thread ends on sewing materials are too long.

Description

technical field [0001] The invention relates to the field of sewing machines, in particular to a thread cutting mechanism and a sewing machine with the same. Background technique [0002] In the thread trimming structure of the sewing machine in the prior art, the length of the remaining sutures (upper thread and bottom thread) on the sewing material after the thread trimming is relatively long. The thread ends are cut off manually, which directly affects the subsequent processing technology, and the whole processing process takes a lot of time. Contents of the invention [0003] The main purpose of the present invention is to provide a thread trimming mechanism and a sewing machine having the same, so as to solve the problem in the prior art that the thread end on the sewing material is too long after thread trimming by the thread trimming mechanism. [0004] In order to achieve the above object, according to one aspect of the present invention, a thread cutting mechanis...
