Problems solved by technology

[0002] The column type sewing machine is a kind of sewing machine. The existing column type sewing machine adopts the tangent method combining the movable knife and the fixed knife. Due to the limitation of the structure, the distance between the tangent point and the needle plate hole is relatively far, resulting The threads on the material are relatively long
Therefore, a special process is required to remove the thread ends, which in turn affects the processing efficiency

Abstract

The invention provides a thread trimming device of a vertical column sewing machine, which comprises a feeding mechanism and a trimming mechanism arranged at one side of the feeding mechanism. By optimizing the thread trimming structure and mode, the problem of long residual thread head of the seam material is solved, the process of the product is simplified, the labor and the thread are saved, and the labor intensity is reduced.

Description

technical field [0001] The invention relates to the technical field of sewing machines, in particular to a thread trimmer of a column type sewing machine. Background technique [0002] The column type sewing machine is a kind of sewing machine. The existing column type sewing machine adopts the tangent method combining the movable knife and the fixed knife. Due to the limitation of the structure, the distance between the tangent point and the needle plate hole is relatively far, resulting The threads on the material are relatively long. Therefore, a special process is required to remove the thread ends, which in turn affects the processing efficiency. Therefore, in view of the above problems, it is necessary to propose a further solution. Contents of the invention [0003] The object of the present invention is to provide a thread trimming device of a column type sewing machine, so as to overcome the deficiencies in the prior art. [0004] In order to achieve the purpos...
