Case sewing processing equipment corresponding to shoulder strap positioning configuration

Abstract

The invention discloses case sewing processing equipment corresponding to a shoulder strap positioning configuration, which structurally comprises a thread inlet guide roller, a guide roller seat, a sewing center, and a machine box, wherein the guide roller seat and the sewing center and the machine box are vertically arranged from top to bottom in sequence to form a sewing driving system, and thethread inlet guide roller is arranged outside an upper end of the sewing center and all signal terminals inside the thread inlet guide roller are electrically connected to one another. By the adoption of the sewing processing equipment corresponding to the shoulder strap positioning configuration, a double-layer positioning formed by a mountain-shaped pressing die and a pressing plate is utilizedto press the mountain-shaped pressing die and the pressing plate on a sewing surface of a shoulder bag, and a formed mountain-shaped structure is matched with a shoulder strap, the shoulder strap ispositioned on an outer lining of the shoulder bag by pressing two sides of the mountain-shaped pressing die, and the mountain-shaped pressing die is in large-area contact with the shoulder bag so as to avoid an influence of over concentration of a lining cotton body on the use comfort; and a left gap is filled with the shoulder strap, the shoulder strap can be prevented from being uneven due to amanual distance measurement by using the model, and in sewing, a sewing needle vertically knits along an inner side of the mountain-shaped pressing die, and esthetic of a sewing edge line of the shoulder strap can be improved along the edge line.

Description

technical field [0001] The invention relates to the field of case and bag manufacturing, in particular, it is a case and bag sewing processing equipment corresponding to the positioning configuration of shoulder straps. Background technique [0002] At present, the stitching of the shoulder straps in the backpack requires the outer fabric, the inner cloth and the shoulder straps to be stitched together. In order to ensure the comfort of the use, the inner lining of the shoulder straps is often filled with some cotton materials, and the stitching of the shoulder straps and the bag body It is necessary to use the blank holder positioning configuration to facilitate better sewing. At present, this positioning configuration has the following defects: [0003] In the positioning configuration, only the compression of the corners is considered. The compression of the corners will easily cause the cotton body inside the shoulder strap to concentrate in one area, resulting in poor c...

AI Technical Summary

Problems solved by technology

[0003] In the positioning configuration, only the compression of the corners is considered. The compression of the corners will easily cause the cotton body inside the shoulder strap to concentrate in one area, resulting in poor comfort;

[0004] In addition, most of the shoulder straps are sewn by manual distance measurement, resulting in uneven shoulder straps after sewing, and the qualified rate of finished products is poor.
