Zipper and rolling line one-time forming device and forming method for manufacturing zipper rolling line

Abstract

The invention discloses a zipper and rolling line one-time forming device and forming method for manufacturing a zipper rolling line. The zipper and rolling line one-time forming device comprises a stitching mechanism, a folding guide unit, a zipper guide unit and a rolling line guide unit, wherein the stitching mechanism is provided with a knit stitch presser foot on a work table. Cloth rolling grooves which are symmetric and are crimped oppositely are formed in the folding guide unit, the cloth rolling grooves are used for making edge wrapping strips which wrap up a rolling line folded in half, and the cloth outlet end of each cloth rolling groove is in butt joint with the cloth inlet end of the knit stitch presser foot; the zipper guide unit is used for leading a semi-finished zipper to the knit stitch presser foot, the cloth outlet end of the zipper guide unit is aligned to the cloth outlet ends of the cloth rolling grooves, the cloth outlet end of the zipper guide unit and the cloth outlet ends of the cloth rolling grooves are arranged up and down, and the semi-finished zipper led out by the cloth outlet end of the zipper guide unit are superimposed with the edge wrapping strips led out by the cloth outlet ends of the cloth rolling grooves in an up-down mode. By means of the device, one-time forming manufacturing of the semi-finished zipper and the rolling line can be achieved, the operation is simple, the work efficiency is high, and the sewn product is high in flatness and high in aesthetic degree.

Problems solved by technology

[0002] In the existing clothes, the zipper is a very common opening and closing part. When the consumer pulls the zipper, the force acting on the zipper is often different or the direction is deviated, causing the zipper to entangle the clothes together in the zipper (that is, the two sides of the zipper) Cloth), and then make the zipper not pull smoothly, and it is easy to tear or scratch the clothes if the force is too large. Therefore, the existing design sews a retaining line (rolling line) on both sides of the zipper of the clothes to prevent the zipper edge cloth from being involved in the zipper In the head, improve the smoothness of the zipper sliding; in order to facilitate the sewing of the zipper blank and the clothes with rolling threads, it is often necessary to sew a layer on the cloth tapes on both sides of the zipper blank during the sewing process. The hemming strip covered with rolling thread, during the production process, the hemming strip is folded in half and covered with rolling thread, and then it is sewn by a sewing machine after ironing; The cloth tapes on both sides of the zipper chain blank are sewn, and the following problems mainly exist in the process of making the entire zipper strip:

[0003] After wrapping the rolling thread, the edge strip can only be sewn with the cloth tape on one side of the zipper chain blank at a time. Therefore, the cloth tapes on both sides of the zipper chain blank need to be stitched twice to complete the production of the zipper strip. Poor performance and inconvenient operation not only increase the workload and working hours of the staff, but also complicate the process and low work efficiency, thereby greatly reducing the production efficiency. At the same time, there are also problems such as asymmetrical sewing on both sides of the zipper strip; in addition, the hemming strip In the sewing process of covering rolled thread, since the hemming strip is made of elastic material, when the hemming strip is covered with rolling thread and sewed, the elastic hemming strip is easy to be pushed away by the sewing machine's presser foot or during the sewing process. Arching due to the stretching effect in the middle, causing the edge strip with rolling line after sewing is not smooth, thus affecting the quality of the product and the later use, aesthetics and good quality of the zipper strip formed after the edge strip and the chain blank are sewn together Rate
