Sewing machine and sewing machine stitch distance adjustment limit device

Abstract

The invention discloses a sewing machine and a sewing machine stitch length adjusting and limiting device. The sewing machine stitch length adjusting and limiting device comprises a stitch length adjusting assembly and a lifting assembly; the stitch length adjusting assembly comprises a first driver; the first driver is connected with a guide rod through a first transmission assembly, the guide rod is used for driving a stitch length adjusting small connecting rod to move, and the guide rod is slidably connected with the interior of a guide sleeve; the first driver is used for driving the guide rod to linearly move in the guide sleeve through the first transmission assembly; the limiting assembly comprises a second driver, and the second driver is connected with a limiting rod through a second transmission assembly; the limiting rod is used for moving under the driving of the second driver so as to lock or unlock the first transmission assembly. The first driver and the second driver are adopted to control the stitch length adjusting process and the locking process after stitch length adjustment, the efficiency is high, and the automation degree of the stitch length adjusting and limiting processes of the sewing machine is high.

Description

technical field [0001] The invention relates to the technical field of sewing equipment, in particular to a sewing machine and a needle distance adjusting and limiting device for the sewing machine. Background technique [0002] At present, the needle distance of industrial sewing machines is generally adjusted manually by a knob. After the needle distance is manually adjusted, the fixed pin must be manually inserted into the position of the limiting mechanism to prevent the needle distance from changing. Although this method is simple, it is less efficient and less automated. [0003] Therefore, how to adjust and limit the stitch length of the sewing machine more efficiently is a technical problem to be solved by those skilled in the art. Contents of the invention [0004] In view of this, the object of the present invention is to provide a sewing machine stitch length adjustment and limiting device, which can more efficiently adjust and limit the sewing machine stitch le...
