Sewing machine providing convenience for needle threading

Abstract

The invention discloses a sewing machine providing convenience for needle threading. The sewing machine comprises a supporting table, a machine body is installed at the top of the supporting table, and a fixing column is arranged at the top of one side of the machine body; a machine head and a sewing needle are arranged at the bottom of one side of the machine body in sequence, sliding rails, first sliding blocks, second sliding blocks, a first fixing plate and a second fixing plate are arranged at the top of the supporting table in sequence, and a guide needle is arranged at one side of the first fixing plate; a groove opening is formed in one end of the guide needle, a laser emitter is arranged at one side of the first fixing plate, a reflection mirror is installed on one side wall of the second fixing plate, and a flexible ruler is installed at one side of the top of the supporting table; a ruler strip and a fixing clamp are connected to one side of the flexible ruler in sequence, and a ruler is installed at the top of the supporting table. According to the sewing machine, the sewing needle can be conveniently used for needle threading, the time required by needle threading is shortened, the working efficiency is improved, the length of sewed cloth can be measured, the accurate length of the cloth is obtained accordingly, processing waste is reduced, and the cloth cost is lowered.

Description

technical field [0001] The invention relates to the technical field of sewing machines, in particular to a sewing machine which is convenient for threading a needle. Background technique [0002] There are many ways to classify sewing machines. The most common ones are based on stitches and uses. The stitches of sewing machines can be classified into two types: lock stitches and chain stitches. Lock stitches are the most common and consist of two stitches. , intertwined like twisted ropes, the interweaving point is in the middle of the sewing material. From the cross-section of the stitch, the two stitches are like two locks locked to each other, so they are called lock stitches. This stitch is used For sewing materials such as cotton, wool fabric or leather with a small shrinkage rate, the front and back sides have the same shape, like a dotted line, and the stitches are densely distributed, and the sewing fastness is generally higher than that of manual sewing.

AI Technical Summary

Problems solved by technology

[0003] Due to the thinner needles of the existing sewing machines, the user generally needs to repeat the thread many times before passing the needles through the needles, which is extremely inconvenient to use. At the same time, the length of the sewing fabric cannot be accurately known when sewing, which often causes Processing waste and lead to increased fabric cost
