Description

Technical Field

[0001] This utility model relates to the field of sewing machine presser foot technology, specifically to a disposable button-attaching presser foot. Background Technology

[0002] In the garment manufacturing industry, button fasteners are a crucial step in connecting garment components and enhancing structural stability and aesthetics. Traditional button fastener processes involve several independent and tedious steps, including hand-cutting buttons, sewing buttons on a flatbed sewing machine, and button fastener attaching using a bartacking machine. These steps are not only time-consuming and require relatively high levels of worker skill, but also have significant shortcomings in terms of production efficiency and cost control.

[0003] Specifically, hand-cutting the buttonholes requires workers to possess a high degree of precision and patience to ensure that the shape and size of the buttonholes meet design requirements. Next, sewing the buttonholes onto the garment using a flatbed sewing machine requires precise stitching, a process that also demands a high level of skill from the workers. Finally, the buttonholes are secured with a bartacking machine to reinforce the seams, improving the garment's durability. However, this entire process is time-consuming and carries the risk of inconsistent quality due to improper human operation.

[0004] Furthermore, traditional button-fastening techniques present several technical challenges. For instance, human error and varying levels of skill often lead to inaccurate button placement and uneven stitching. These issues not only affect the garment's appearance but can also cause the buttons to detach or become damaged during use, thus reducing the garment's durability and wearing experience.

[0005] To address the aforementioned issues, this project developed a novel one-time buttonhole presser foot technology. This technology aims to combine multiple cumbersome steps in the traditional process into one, thereby improving production efficiency, reducing the skill requirements for workers, and ensuring the stitching position and quality of the buttonhole. Utility Model Content

[0006] To address the aforementioned issues, a new type of presser foot for one-time fastening is provided. Through the presser foot mechanism, the problem of low work efficiency caused by the complex three-step process in the existing technology is solved.

[0008] Preferably, the winding assembly includes a support block; the support block is disposed on top of the connecting foot and above the sewing machine worktable.

[0009] Preferably, the support block has an opening in the middle for the strip of fabric to pass through; the opening is oriented towards the front of the sewing machine.

[0010] Preferably, the winding assembly further includes a threading block; the threading block is disposed on the top of the support plate, and the threading block has a through hole in the middle for the strip of cloth to pass through and be wound; the through hole is elliptical in shape.

[0011] Preferably, the support block is U-shaped; the lower end face of the support block can extend outward from the connecting foot.

[0012] Preferably, the winding assembly further includes a mounting plate; the mounting plate is disposed at the bottom end of the threading block and located at the top of the support block; the threading block is elliptical in shape.

[0013] Preferably, the threading block is made of a rigid material.

[0014] Preferably, the support block is made of a rigid material.

[0015] The advantages of this utility model compared to the prior art are:

[0016] 1. By setting up a winding component, this utility model significantly reduces sewing time, ensures sewing accuracy, shortens the processing time of each buckle to thirty seconds, achieves zero rework and repair, significantly improves product quality, and reduces the technical requirements for operators, thereby greatly improving production efficiency.

[0024] To further understand the features, technical means, and specific objectives and functions achieved by this utility model, the following detailed description of this utility model is provided in conjunction with the accompanying drawings and specific embodiments.

[0025] See Figures 1-6 As shown, the disposable buttonhole presser foot includes a connecting foot 1 installed on the side of the sewing machine; the connecting foot 1 is V-shaped; the presser foot also includes a winding assembly 2; the winding assembly 2 is located on the top of the connecting foot 1.

[0026] First, the garment to be processed is placed in the sewing machine's working area. Then, the garment is processed and buttonholes are sewn on using the thread winding assembly 2. This workflow combines the existing three steps of manually cutting buttonholes, sewing buttonholes on a flatbed sewing machine, and attaching buttonholes on a barn door into one, completing the barn door and buttonhole attachment in one go. Following the improved barn door sewing method, buttonhole attachment is completed in one go in 30 seconds, compared to 56 seconds for a flatbed sewing machine and 18 seconds for a barn door sewing machine before the improvement. This represents a 59% increase in production efficiency and effectively replaces skilled workers. It ensures sewing accuracy and significantly improves product quality. Furthermore, the operation is simple, reducing the technical requirements for operators and greatly increasing production efficiency. Before the improvement, the average processing time per garment was 74 seconds, but the rework rate was 10%, and 486 garments could be completed per day. After the improvement, the processing time per garment is 30 seconds, with no rework or rework, and 1200 garments can be completed per day.

[0027] See Figure 2 and Figure 3 As shown, the winding assembly 2 includes a support block 21; the support block 21 is disposed on top of the connecting foot 1 and located above the sewing machine worktable.

[0028] The support block 21 can press the garment to be processed above the working area of ​​the sewing machine, and can prevent the garment to be processed from shifting during processing.

[0029] See Figure 4 and Figure 5 As shown, the support block 21 has an opening 211 in the middle for the strip of fabric to pass through; the opening 211 is oriented towards the front of the sewing machine.

[0030] The garment to be processed is placed at the bottom of the support block 21, and in this state, the garment to be processed can be supported by the support block 21.

[0031] See Figure 6As shown, the winding assembly 2 also includes a threading block 22; the threading block 22 is disposed on the top of the support plate, and the threading block 22 has a through hole 221 in the middle for the strip of cloth to pass through and be wound; the through hole 221 is elliptical in shape.

[0032] First, the strip of fabric is passed through the oval-shaped perforation 221 at the top of the threading block 22. Then, the fabric is overlapped and folded over the outer area of ​​the connecting leg 1. Next, the fabric is wrapped around the opening 211 in the middle of the support block 21, at which point the strip of fabric is effectively held against the garment to be processed by the support block 21. The sewing machine then begins operation. The strip of fabric, passed through the threading block 22 and overlapped in the opening 211, is sewn to the garment to be processed, which is pressed against the bottom of the support block 21. After sewing, the worker uses scissors to trim any excess fabric or garment. The sewing process for the garment to be processed is now complete.

[0033] See Figure 5 and Figure 6 As shown, the support block 21 is U-shaped; the lower end face of the support block 21 can extend outward from the connecting leg 1.

[0034] The strips of fabric can be overlapped or wrapped through the opening 211 on the support block 21.

[0035] See Figure 5 and Figure 6 As shown, the winding assembly 2 also includes a mounting plate 23; the mounting plate 23 is disposed at the bottom end of the threading block 22 and located at the top of the support block 21; the threading block 22 is elliptical in shape.

[0036] Mounting plate 23 can be installed on top of support block 21 by welding, and wire threading block 22 is also fixed to mounting plate 23 by welding.

[0037] See Figure 6 As shown, the wire threading block 22 is made of a rigid material.

[0038] The material of the threading block 22 is preferably a rigid material made of iron.
