Problems solved by technology

During the sewing feeding process, the large presser foot presses the fabric and moves back and forth on the surface of the sewing table with the sewing of the machine needle. There is a pressure between the surface of the table, and the movement of the cloth will cause friction between the cloth and the surface of the sewing table. When such friction lasts for a long time, it will cause irreparable friction damage to some cloth, resulting in The decline in the sewing quality of fabrics will affect the appearance, and even affect the economic benefits of garment manufacturers

Embodiment 1

[0024] Such as figure 1 , figure 2 with image 3 As shown, a large presser foot of a bag opening machine, the bag opening machine includes a sewing table 7 and a large presser foot 1 with a presser foot assembly 12 and a mounting plate 11, and one end of the mounting plate 11 is provided with a foot lifting shaft. The large presser foot of the bag machine includes a cladding plate arranged directly below the presser foot assembly 12 and attached to the sewing table 7 . The presser foot assembly 12 comprises two presser foot arms 2 arranged in parallel and all hinged on the lifter shaft and two parallel presser foot bodies 3 respectively fixed on one end of the above two presser foot arms 2 by bolts. The other end of mounting plate 11 is fixed with two air cylinders 6, and the piston rods of two air cylinders 6 are respectively hinged on two presser foot arms 2 other ends. The cladding plate 4 is fixedly connected with the mounting plate 11 by bolts, and one side of the cla...

Embodiment 2

[0028] The working principle and structure of the large presser foot of the bag opening machine in the second embodiment are basically the same as those of the large presser foot of the bag opening machine in the first embodiment, the difference lies in:

[0029] Such as Image 6 As shown, the above-mentioned application board 4 can also be a strip-shaped elastic board. Gaps in the sewing fabric.

[0030] The application plate 4 in the above two embodiments can also be replaced by a strip-shaped rigid plate, and the selection of a strip-shaped elastic plate in the embodiments is only as a preferred solution.

Abstract

The invention provides a big presser foot of a bag opening machine, and belongs to the technical field of sewing machines. The big presser foot solves the problem that the big presser foot of the traditional bag opening machine enables fabric to be worn in the using process, thus the beautiful appearance is influenced. The big presser foot of the bag opening machine is arranged on a sewing platenand comprises a mounting plate which is arranged on the platen and can slide in a reciprocating way and a presser foot assembly articulated on the mounting plate, wherein the lower part of the mounting plate is fixedly connected with a platy compression board, and the compression board is attached to the surface of the platen and positioned right below the presser foot assembly. The big presser foot of the bag opening machine can fix the fabric between the presser foot body and the compression board, enables the fabric to be maintained to be static relative to the big presser foot and movablerelative to the sewing platen, reduces the friction between the fabric and the sewing platen to the maximum extent, and guarantees and improves the sewing quality of the fabric.

Description

technical field [0001] The invention belongs to the technical field of sewing machines, and relates to a large presser foot, in particular to a large presser foot of a bag opening machine. Background technique [0002] As a garment processing equipment, bag opening machine plays an important role in modern garment production. In the prior art, a large presser foot for assisting sewing is provided on the sewing table of the bag opening machine, including a presser foot mounting plate, a presser foot arm, and a presser foot body. The presser foot mounting plate is used to fix the presser foot arm. The presser foot arm is used to connect the presser foot body and the presser foot mounting plate, and at the same time drive the presser foot body to lift and press down. The presser foot moves to the proper position to press the fabric. [0003] When the bag opener is working, the operator moves the presser foot mounting plate to push the large presser foot towards the operator, ...
