Description

Combined automatic chopper of sewing machine

Technical Field

The utility model relates to a sewing machine technical field, in particular to combined type automatic chopper of sewing machine.

Background

A sewing machine is a machine that uses one or more sewing threads to form one or more stitches in a material to be sewn, thereby interweaving or stitching one or more layers of material. The sewing machine can sew fabrics such as cotton, hemp, silk, wool, artificial fiber and the like and products such as leather, plastic, paper and the like, and the sewed stitches are neat, beautiful, flat and firm, the sewing speed is high, and the use is simple and convenient. And derives the artistic forms of hand-push embroidery, computer embroidery, etc. The sorting methods of sewing machines are many, and it is common to distinguish between stitches and uses. The stitches of a sewing machine can be classified into two types, lock stitches and chain stitches. Lock-stitch stitches are most commonly made up of two stitches that are interwoven like a twine with the point of interweaving in the middle of the material. Two stitches are like two locks locking each other when viewed in cross section of the stitch, and are therefore called lock stitches. The stitch is used for sewing materials such as cotton, wool fabric or leather with small shrinkage rate, and the front and the back of the stitch have the same shape as a dotted line. The stitches are distributed densely, and the sewing fastness is generally higher than that of manual sewing.

When the conventional sewing machine sews the binding strip, the binding strip needs to be cut short manually, so that extra manpower needs to be wasted, and the working efficiency is low.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to overcome above-mentioned prior art not enough, provide a sewing machine combination formula automatic chopper, direct equipment is on sewing machine, realizes the automatic bundle strip after cutting off the sewing, provides work efficiency.

The utility model discloses a realize like this, a sewing machine combination formula automatic chopper, the faller one end at sewing machine is installed to automatic chopper, include the support and install the cylinder in the support outside, cylinder bottom swing joint has the base, the base bottom is fixed with the knife rest, the one end that the knife rest is close to the faller is the setting of buckling downwards, knife rest one end is fixed with and is fore-and-aft movable blade, faller one end is fixed with the fixed blade that is the level and places, the fixed blade surface is the slope setting, movable blade corresponds and establishes at fixed blade top.

In some embodiments, an air nozzle and an adjusting switch are arranged on one side of the air cylinder.

In some embodiments, the inner side of the bracket is provided with a nut piece, and a screw is arranged in the nut piece to fix the air cylinder on the outer side of the bracket.
