Description

Technical Field

[0001] The utility model relates to the technical field of luggage processing auxiliary equipment, in particular to an auxiliary tooling for sewing luggage zippers. Background Art

[0002] The manufacturing process of bags is very complicated, usually including design, material selection, cutting, sewing, assembly and other steps. Among them, the sewing step includes sewing the pre-prepared zipper on the fabric at the opening of the bag. At present, operators sew the zippers of bags with the help of sewing machine equipment according to the following process: first, according to the design of the bag, measure the required zipper length; then, place the zipper in the correct position of the bag fabric, usually with the zipper teeth facing down, corresponding to the right side of the fabric; secondly, use pins or sewing clips to temporarily fix the zipper position to prevent it from moving during the sewing process; finally, use the zipper foot or ordinary presser foot to sew on both sides of the zipper.

[0003] In order to effectively improve the sewing effect of bag zipper sewing and improve the sewing efficiency, those skilled in the art have made relevant designs for the sewing tooling of bag zipper sewing. For example, Chinese patent document CN217895916U discloses a zipper sewing auxiliary tooling for bag processing. The auxiliary tooling limits the fixed seat on the sewing machine through positioning bolts, and the connecting rod and the support plate are installed at the rear of the upper end of the fixed seat through splicing bolts and are rotatably connected with it. When the splint is in use, it is manually rotated to the sewing area. When not in use, it can be turned away from the sewing area. It does not need to be disassembled and can be used at any time, which is convenient and quick.

[0004] However, the existing auxiliary tooling for sewing luggage zippers is difficult to meet production needs. For example, before sewing, the operator needs to repeatedly compare the placement of the zipper, which reduces the sewing efficiency of the zipper. In another example, when the sewing machine is sewing the zipper to the fabric, as the fabric and the zipper are pulled, the temporary limiting structure of the sewing clip has a poor fixing effect, the path of the stitching line is easily offset, and even the needle of the sewing equipment may interfere with the zipper teeth, thereby affecting the sewing effect of the zipper.
