Description

Technical Field

[0001] The utility model relates to the technical field of clothing processing equipment, in particular to a limiting device for a straight-mouth zipper. Background Art

[0002] Fabric straight-mouth is a decorative zipper processing method commonly used in clothing production. It is usually used in clothing styles such as skirts, pants, and tops to add an opening to the side seam or the middle of the back of the clothing for easy wearing and taking off. The characteristics of the straight-mouth are that it is highly decorative and practical. Through the processing of the straight-mouth, details and design sense can be added to the clothing, making the overall shape more diverse. Moreover, the straight-mouth also provides a convenient way for the wearer to put on and take off, avoiding the trouble of passing through the head or waist. Zippers usually need to sew the two sides of the zipper to the two sides of the fabric respectively, and then sew the central part of the zipper together. When using an ordinary sewing machine presser foot, since the pressure of the sewing machine presser foot is evenly distributed, it is difficult to fit the two sides of the zipper tightly to the fabric, resulting in uneven zipper sewing or deviation of the seams. The zipper presser foot can effectively solve these problems.

[0003] The existing zipper presser foot needs to be changed in size when processing zippers of different widths. Often, a piece of clothing has multiple zippers of different widths, which requires frequent changes in the size of the presser foot during sewing, resulting in low processing efficiency.

[0004] In view of this, we propose a limiting device for a straight-mouth zipper. Utility Model Content

[0008] Furthermore, the presser foot adjustment assembly includes a bracket, and an opening one is opened at the top of one side of the surface of the bracket, and the opening one penetrates the one side of the surface of the bracket and extends to the other side of the surface of the bracket.

[0009] Furthermore, a lifting ear is fixedly installed at the bottom center of the fixing seat, and the lifting ear is rotatably connected to an opening on the surface of the bracket through a metal rod, and a pressing plate is fixedly installed at the bottom of the fixing seat.

[0010] Furthermore, a second opening is provided in the middle of one side of the surface of the bracket, and the second opening is arranged at the bottom of the first opening. The second opening passes through one side of the surface of the bracket and extends to the other side of the surface of the bracket.

[0011] Furthermore, a third opening is provided at the bottom of one side of the surface of the bracket, and the third opening is arranged at the bottom of the second opening. The third opening passes through one side of the surface of the bracket and extends to the other side of the surface of the bracket.

[0012] Furthermore, a side panel is provided on one side of the bracket, a sliding rod is fixedly installed on the top of one side of the surface of the side panel, a metal rod is rotatably connected to the bottom of one side of the surface of the side panel, and one end of the metal rod passes through the side panel and is fixedly installed with a rotating handle.
