Abstract

The invention provides an automatic lifting device for a presser foot of a bar tacking machine. The device comprises the presser foot and a lifting mechanism, wherein the presser foot is connected with the lower end of a presser bar; the upper end of the presser bar is provided with a presser slide block; the lifting mechanism is connected with the presser slide block; the lifting mechanism comprises a main shaft, a pushing ram, a connecting rod and a lifting rod. Through the lifting mechanism, automatic lifting of the presser foot of the bar tacking machine can be realized; and through the presser foot structure, the phenomenon of skipping stitch in a sewing process of the bar tacking machine is prevented through the presser foot structure, thereby ensuring nice patterns of stitching.

Description

technical field [0001] The invention relates to a presser foot lifting device, in particular to a tacking machine presser foot lifting device. Background technique [0002] The tacking machine is a special sewing equipment for bags, leather, labels, etc. It is mainly used for decorative sewing. The tacking machine in the prior art mainly drives the driving shaft through a direct-drive servo motor, and drives the tacking machine to move along the X-axis and the Y-axis through a stepping motor. Some tacking machines also use computer control to complete various patterns of sewing through programming software. [0003] The tacking machine of the prior art lacks a presser foot device, and stitch skipping occurs during the sewing process, which can cause defects such as unsightly stitch patterns. Contents of the invention [0004] In order to solve the technical defect that the tacking machine does not have a presser foot device in the prior art, and stitch skipping is likely...
