Embodiment

[0017] Example: such as figure 1 As shown, the presser foot 1 includes a presser foot seat 14 and a presser foot plate 11 , and the presser foot seat 14 is connected to the transmission rod 2 . Presser foot seat 14 and presser foot plate 11 are provided with presser bar 12 and connecting rod 13, one end of presser bar 12 is hinged on presser foot seat 14, and the other end is hinged at the middle part of presser foot plate 11, and presser foot plate 11 follows presser bar 12 Rotate relative to the presser foot seat 14, the rotation angle of the pressure rod 12 is a rotation angle a, and the rotation angle a is 1°-5°. The presser foot seat 14 is provided with a rotating groove 141, and one end of the pressing rod 12 is hinged in the rotating groove 141. The rotating groove 41 is provided with a rib that limits the rotation angle of the pressing rod 12. The angle between the two ribs is the same as that of the pressing rod 12 The corner a is the same. One end of the connecting...

Abstract

The invention relates to the technical field of bartack sewing machines, in particular to a presser foot used for a bartack sewing machine. The presser foot comprises a presser foot base and a presser foot plate. A pressing rod and a connection rod are arranged between the presser foot base and the presser foot plate. One end of the pressing rod is hinged to the presser foot base, and the other end of the pressing rod is hinged to the middle of the presser foot plate. The presser foot plate rotates relative to the presser foot base together with the pressing rod. The rotation angle of the pressing rod is alpha. One end of the pressing rod is hinged to the end of the presser foot plate, and the other end of the pressing rod is connected into a slide groove in the presser foot base in a sliding mode. The presser foot is simple in structure, wide in application range and good in cloth pressing effect, the angle of the presser foot plate can be automatically regulated, and unsmooth and uneven cloth can be effectively pressed; meanwhile, the pressing rod rotates to generate an included angle smaller than 90 degrees relative to the horizontal plane after the pressing rod is pressed downwards. When the cloths moves reversely, the pressing force can be improved, the processed cloth can only enter the bartack sewing machine but can not leave the bartack sewing machine, and the cloth is prevented from being scratched when moving reversely.

Description

technical field [0001] The invention relates to the technical field of tacking machines, in particular to a presser foot for tacking machines. Background technique [0002] The tacking machine is also called a jujube cart or a knotting machine. It is usually used to strengthen the stitches. It is generally suitable for garments, knitting, sweaters, suits, jeans and other manufacturers. The tacking machine mainly plays the role of clothing receiving The role of the reinforcement section sewing of the force part, the reinforcement of the seam tail of the round head buttonhole and the top circle of the sewing lock umbrella. In the past, after the button was bound in the production process, it was necessary to manually wrap several times with sewing thread behind the button neck to reinforce the button. Firmness, now the tacking machine can automatically operate this process, shorten the working time, improve production efficiency, reduce the production intensity of workers, and...
