Description

Technical Field

[0001] This utility model relates to the field of sewing machine technology, specifically to a special presser foot for zipper installation in garment production. Background Technology

[0002] In the garment manufacturing industry, zipper installation is a common yet challenging task, especially when using automated quilting equipment, which typically relies on pre-programmed quilting operations. Currently, traditional presser feet are widely used in zipper installation. However, traditional presser feet have a significant drawback when applied to zipper installation: due to the inherent structural characteristics of zippers, their heads have a protruding portion. When using a traditional presser foot, this protrusion obstructs the normal passage of the presser foot, thus affecting the efficiency of zipper installation.

[0003] In existing zipper installation processes, overcoming this problem usually requires secondary processing of the zipper installation step. This not only increases the complexity of the operation, prolongs the zipper installation time, and reduces production efficiency, but may also introduce more errors due to multiple processing steps, adversely affecting the quality of the final product. Utility Model Content

[0004] To address the aforementioned technical problems, this application resolves the issue of requiring secondary processing in the zipper installation step. This not only increases operational complexity and prolongs zipper installation time but also reduces production efficiency.

[0005] To achieve the above objectives, the technical solution adopted in this application is as follows: a special presser foot for zipper installation in garment production, comprising a presser foot fixing rod, wherein a presser foot housing is provided at the bottom of the presser foot fixing rod.

[0006] The presser foot housing includes a shell body, which is a hollow structure with an open top. The bottom of the shell body on the left front side of the presser foot fixing rod has a tunnel notch that is vertically connected to the presser foot housing along the front and rear directions. A track support block is provided on the left wall of the shell body. The tunnel notch and the track support block together form a presser foot tunnel arranged along the front and rear directions.

[0007] To better realize this utility model, the presser foot fixing rod further includes a fixing rod body, and the top surface of the fixing rod body is provided with a vertical through installation channel;

[0008] The bottom of the fixing rod body is integrally formed with a connecting seat. The bottom of the connecting seat is connected to the top edge of the right rear side of the shell body. The rear side of the connecting seat is provided with a vertical through mounting groove. The rear side of the fixing rod body is flush with the inner bottom surface of the mounting groove to form a mounting surface.

[0009] The mounting surface has a straight groove that communicates with the mounting channel.

[0010] To better realize this utility model, the bottom of the shell body located on the right side of the tunnel opening is further configured as a plane parallel to the top edge of the shell body.

[0011] To better realize this utility model, the inner top surface of the tunnel opening is parallel to the top edge of the shell body;

[0012] To better realize this utility model, the track support block further includes a track support block body, the top of the track support block body is connected to the left wall of the shell body, the bottom surface of the track support block body is flush with the bottom plane of the shell body, and the right side of the track support block body is parallel to the right inner wall of the tunnel gap.

[0013] The technical solution provided by this utility model has the following advantages compared with the prior art:

[0014] 1. This utility model significantly improves installation efficiency. Traditional presser feet cannot pass through properly when installing zippers because the zipper head protrudes, requiring secondary processing, which greatly reduces installation efficiency. This tunnel presser foot, however, can easily pass through the zipper head, avoiding secondary processing and simplifying the originally complex zipper installation process into a single step. This greatly shortens zipper installation time, significantly improves the efficiency of zipper installation in garment production, makes the entire production process smoother and more efficient, and helps improve the overall production efficiency of garment manufacturing.

[0015] 2. This invention significantly reduces operational difficulty. Traditional zipper installation methods, due to the aforementioned problems, require a high level of skill and operational proficiency from the operator, necessitating manual adjustment to overcome the obstruction of the zipper head on the presser foot. However, with this tunnel presser foot, operators no longer need to address the operational obstacles caused by the protruding zipper head, making operation simpler, reducing skill requirements, minimizing human error during operation, and thus improving product quality stability and consistency.

[0016] 3. This utility model is well adapted to automated production. The tunnel presser foot is suitable for automatic quilting equipment that relies on pre-programmed quilting processes, and can be seamlessly integrated into the automated workflow of garment production. By reducing operational steps and simplifying operation, the reliability and smoothness of automated equipment in the zipper installation stage can be improved, reducing downtime or errors caused by zipper installation problems. This provides strong support for the automation and intelligentization of garment production, and helps improve the automation level and production management efficiency of garment manufacturing enterprises.

[0017] 4. This invention offers excellent customization flexibility. The tunnel presser foot's tunnel dimensions are determined based on the product's zipper size, and the entire structure is fabricated using a 3D printer after a model is built. This manufacturing method not only enables rapid production but also offers high flexibility, allowing for customized production based on zippers of different sizes. This meets the zipper installation requirements of various garment products, improving the presser foot's applicability and versatility, enabling it to perform well in a variety of garment production scenarios.

[0018] 5. This utility model offers excellent cost-effectiveness. By reducing the zipper installation process, it avoids the additional manpower, material, and time costs that might arise from secondary processing. Furthermore, it allows for flexible manufacturing via 3D printing, thereby reducing garment production costs to a certain extent. Simultaneously, it improves production efficiency and product quality, bringing considerable economic benefits to garment manufacturers from a comprehensive cost-benefit perspective.
