Abstract

The invention provides a strip cutting structure for a patchwork sewing machine, which belongs to the technical field of sewing machines. It solves the problem of low efficiency of pasting strips in the existing seaming machines. The stitching machine includes a machine head, which is fixedly connected with a mounting shell, and the cutting structure includes a rotatable cam installed in the mounting shell, a sliding bar that is installed in the mounting shell and can move up and down along the mounting shell, and a fixed connection. On the mounting base at the bottom of the sliding bar and the chopping knife arranged on the mounting base, the rotation of the cam can push the sliding bar to move downward, and a resetting part that can make the sliding bar move upward and reset is provided between the sliding bar and the mounting shell. The tape cutting structure of the patchwork machine improves the efficiency of tape bonding on the basis of ensuring stability.

Description

technical field [0001] The invention belongs to the technical field of sewing machines, and relates to a strip cutting structure of a patchwork sewing machine. Background technique [0002] Four-needle six-thread patchwork sewing machine is mainly used for splicing and merging of seams. It is composed of four upper threads, one bottom thread and one Hasu thread. It has a unique high-elastic, flat and high-strength patchwork effect. . [0003] In the process of sewing, the stitching machine needs to cut the tape. The existing tape cutting structure, for example, the Chinese patent literature discloses a tape machine with an improved structure [application number: 201020142536.4; authorized announcement number: CN201665765U ], which comprises a sewing machine body, the body of the sewing machine body is provided with an unwinding stand, the needle presser foot of the sewing machine body is provided with a flat sleeve in front of it, the sleeve is vertically arranged, and its ...
