Abstract

The invention provides an over-edging sewing machine automatically cutting fabric and cutting a over-edging strip, and belongs to the technical field of sewing equipment manufacturing. The over-edgingsewing machine solves the technical problem that an existing over-edging sewing machine is monotonous in function, low in efficiency and the like. The over-edging sewing machine comprises a machine shell, a main shaft and a needle rod capable of reciprocating vertically, a clutch support is connected to the main shaft through a connecting rod, and the main shaft can drive the clutch support to reciprocate vertically; the machine shell is provided with a cutter base and a lifting base, wherein the cutter base and the lifting base can move vertically, a fabric cutter is fixedly connected to thecutter base through a cutter mounting frame, and a cutter is fixedly connected to the lifting base; the cutter base is further provided with a locking rod capable of making the clutch support connected with the cutter base; the lifting base is provided with a movable pin capable of being inserted into the cutter base, and the machine shell is provided with a driving part driving the movable pin to move. By means of the over-edging sewing machine, a power source of the over-edging sewing machine itself can be adopted to automatically cut fabric edges, the over-edging strip and a bottom face line, and the efficiency is high.

Description

technical field [0001] The invention belongs to the technical field of sewing equipment, and relates to a hemming sewing machine, in particular to a hemming sewing machine which can automatically cut cloth and cut hemming strips. Background technique [0002] The hemming sewing machine is used to oversew the edges of flexible fabrics with a certain thickness, which not only makes such fabrics more beautiful, but also increases the strength of the fabrics. Existing hemming sewing machines have functions such as automatic backstitching, automatic thread clamping, automatic thread pulling, and automatic presser foot lifting. Due to the influence of hemming faucets and funnels, the structure is restricted and interfered. Ordinary hemming sewing machines do not have such functions. Set the functions of automatically cutting the hemming strip, cutting the bottom thread and cutting the fabric. When using the hemming sewing machine to hem the fabric, after the hemming sewing of the ...
