Abstract

The invention provides a presser foot device of a bar tacking machine, which comprises a middle presser foot, a presser foot bar and a lifting bar, wherein the middle presser foot is connected to the lower end of the presser foot bar, the upper end of the presser bar is provided with a middle presser foot slide block, a connecting pin is arranged on the lifting bar, the lifting bar rotates up anddown by using the connecting pin as a center, and the lifting bar is in contact connection with the middle presser foot slide block. The presser foot device also comprises a work lifting mechanism and a pneumatic lifting mechanism. The invention can effectively prevent bouncing pin phenomenon of the bar tacking machine during the sewing so as to enable a sewn wire to reach the industrial standardrequirements and enlarge the sewing range.

Description

technical field [0001] The invention relates to a presser foot device, in particular to a presser foot device for a tack machine. Background technique [0002] Tacking machine is a special sewing equipment for bags, leather, labels, etc. It is mainly used for repeated sewing of sewing stitches and plays a processing role. It is also called a reinforcement machine. 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 prior art does not have intermediate presser foot device, and after the material is pressed tightly by the edge of the outer presser foot, it is repeatedly sewed to reinforce, so it can only sew the scope of 30mm * 10mm. When the sewing range is expanded, especially wh...
