Abstract

The invention provides a needle bar stroke adjusting mechanism and a sewing machine with the same. The needle bar stroke adjusting mechanism comprises a crank, an adjusting assembly and an upper shaft, wherein the adjusting assembly is connected with a needle bar, at least part of the adjusting assembly is adjustably arranged on the crank, and the stroke of the needle bar is adjusted by adjustingthe position of at least part of the adjusting assembly; and the upper shaft is connected with the crank, the needle bar is driven to reciprocate by driving the crank to move, and the problem that a sewing machine in the prior art is low in production efficiency is solved.

Description

technical field [0001] The invention relates to the field of sewing, in particular to a needle bar stroke adjustment mechanism and a sewing machine with the same. Background technique [0002] In the sewing process, due to the different types of materials to be sewn, it is necessary to adjust the formation of the needle bar of the sewing machine. Most of the needle bar strokes on the existing sewing machines cannot be adjusted. Even if they can be adjusted, the operation is cumbersome and reduces the production of the sewing machine efficiency. Contents of the invention [0003] The main purpose of the present invention is to provide a needle bar stroke adjustment mechanism and a sewing machine with it, so as to solve the problem of low production efficiency of the sewing machine in the prior art. [0004] In order to achieve the above object, according to one aspect of the present invention, a needle bar stroke adjustment mechanism is provided for adjusting the movement ...
