The fabric pulling lifting slider slides on one side of the fabric pulling lifting guide rail, positioning, pulling, clamping, and overlapping the zipper and fabric. During zipper sewing, a small area of the lining and fabric that contacts the zipper is folded, creating a folded shape. This results in four layers of fabric, clamping one side of the zipper in the middle, significantly increasing the strength of the sewn zipper. This method does not require adding more fabric layers to increase zipper strength; it only requires small folds to increase the number of layers in contact with the zipper. This not only enhances the zipper's sewing strength but also saves fabric. The fully automated operation significantly improves production efficiency and reduces labor costs. Strict multi-layer automatic sewing avoids quality problems such as inconsistent lengths, wrinkles, and unevenness. Attached Figure Description

A cloth-pulling lifting synchronous pulley belt 42 and an upper bearing 43 are fixedly connected to the top of the cloth-pulling lifting base arm 36. A multi-rail cloth-pulling lifting motor 44 is fixedly connected to the top of the cloth-pulling lifting base arm 36. A lifting drive synchronous pulley 46 is fixedly connected to the output end of the multi-rail cloth-pulling lifting motor 44. The lifting drive synchronous pulley 46 is connected to the cloth-pulling lifting synchronous pulley belt 42. A multi-rail cloth-pulling motor mounting plate 45 is fixedly connected to the top of the cloth-pulling lifting base arm 36.

[0032] It should be noted that, in this process, the positioning clamping lifting cylinder 11 is activated to drive the zipper fabric positioning clamping and shifting assembly 12 to rise, and the rotation of the fabric pulling lifting screw 39 drives the multi-track fabric pulling assembly 48 to fall. The fabric pulling lifting slider 38 slides on one side of the fabric pulling lifting guide rail 37, driving the multi-track fabric pulling assembly 48 to insert the hook into the lower part of the positioning piece of the zipper fabric positioning clamping and shifting assembly 12, pulling the already pressed upper fabric to the lower part of the positioning piece and clamping it, and then removing the hook and driving the multi-track fabric pulling assembly 48 to return to its original position. The zipper fabric positioning clamping and shifting component 12, with the folded upper fabric in place, is driven by the positioning clamping and lifting cylinder 11 to descend to the zipper positioning and straightening plate component 14 (folded edge, zipper clamped, straightened, bottom fabric) and overlap the zipper and bottom fabric on top of the placket bottom fabric suction positioning component 15. The zipper fabric positioning clamping and shifting component 12, which overlaps the folded upper fabric, zipper, bottom fabric, and zipper positioning and straightening plate component 14, is driven by the rotating positioning folding plate drive motor 6 and the hollow platform rotary motor to rotate together between the independent lifting double needle sewing head and the independent lifting rotary shuttle seat for synchronous sewing.
[0033] By folding a small area of the lining fabric along the side that contacts the zipper, creating a folded shape, the lining and fabric fold together to form four layers of fabric when sewn to the zipper. This sandwiches one side of the zipper in the middle, significantly increasing the strength of the zipper after sewing. This method does not require adding more layers of fabric to increase the zipper's strength; it only requires folding a small area of the existing fabric to increase the number of layers in contact with the zipper. This not only enhances the zipper's sewing strength but also saves fabric. Furthermore, both sides of the zipper can be sewn together in one go, greatly reducing the zipper sewing time.
[0034] Finally, the following points should be noted: First, in the description of this application, it should be noted that, unless otherwise specified and limited, the terms "installation", "connection", and "linkage" should be interpreted broadly, and can be mechanical or electrical connections, or internal connections between two components, or direct connections.
