Description

A sewing machine with a wrinkle-free feeding structure

technical field

The utility model relates to the technical field of sewing machines, in particular to a sewing machine with a wrinkle-free feeding structure.

Background technique

A large number of sewing machines are used in clothing, shoe bags and other industries for sewing processing. A sewing machine is a machine that can interweave or sew one or more layers of cloth, leather, etc. It is durable and fast in sewing speed, which can improve the efficiency of sewing processing;

For example, the sewing machine whose publication number is CN207109291U is a kind of fortification thread winding structure, which includes a sewing machine base, an auxiliary driving wheel, a sewing machine head, a main driving wheel, a driving belt and a thread take-up lever, etc., and the thread take-up lever drives the sewing thread to realize reciprocating fast movement. , the limit sleeve can limit the movement track of the sewing thread (that is, it is located within the range limited by the limit sleeve), thereby preventing the sewing thread from being caught by surrounding objects and causing thread breakage. When it is necessary to change the size of the limit space (that is, the space for the movement of the sewing thread), the lifting rod is driven up and down through the lifting mechanism. The shaft head rotates to drive the limit sleeve to rotate, so that the projected area of the limit sleeve changes, thereby realizing the change of the limit space. Therefore, the change of the limit sleeve is carried out synchronously, and the convenience of adjustment is good;

However, this sewing machine lacks a feeding structure in actual use, so that the sewing machine does not need to manually push the cloth or leather to move during the working process, making it impossible to interweave and sew the cloth or leather in time and quickly. After working, the speed will slow down, which will affect the processing efficiency of the sewing machine, and there are certain defects.

Therefore, we have proposed a sewing machine with a wrinkle-free feeding structure that can well solve the above problems.
