Description
Technical Field
[0001] This application relates to the field of sewing technology, and in particular to a sewing auxiliary component. Background Technology
[0002] Sewing is widely used in garment manufacturing, especially in functional apparel and high-end products, where the addition of special decorative elements is a crucial means of enhancing product value. For example, in sportswear and safety clothing, reflective strips not only enhance visual appeal but also improve safety. However, as consumers increasingly demand both aesthetic appeal and durability from ready-made garments, traditional sewing techniques face new challenges. In the sewing industry, the presser foot is an essential component of the sewing machine's feeding mechanism. It is typically located in the sewing area of the worktable used to hold the fabric, specifically between the sewing needle and the worktable. It is an important component of the sewing machine, responsible for holding down the fabric so that it can move forward smoothly and ensuring the accuracy and stability of the sewing. The presser foot is mainly composed of the presser foot body and the base. The presser foot body usually consists of two horizontal presser foot parts that press against the sewing area. When the operator sits at the front of the sewing machine, the base is positioned above the sewing area away from the operator. The presser foot body is installed between the base and the operator, with both presser foot parts facing the operator. A sewing hole is set between the two presser foot parts, through which the sewing needle can pass freely. The sewing hole is set in accordance with the sewing area. When the fabric is pushed, the drive rack of the sewing area drives the fabric to move directly below the sewing hole.
[0003] Currently, common solutions for achieving precise fixation of reflective strips include using a four-needle, six-thread sewing machine and relying on manual experience to hold the fabric and reflective strip down with the presser foot during sewing, or manual positioning and assisted sewing. Additionally, some companies choose to use pre-treatment processes, such as temporarily fixing the strip with adhesive before sewing, in an attempt to reduce quality issues caused by reflective strip displacement. However, these methods generally have certain limitations. Manual positioning and sewing is not only time-consuming and labor-intensive but also reduces efficiency and increases the rework rate; furthermore, the reflective strip is prone to displacement during sewing. Utility Model Content
[0004] In order to simplify the sewing process, improve processing efficiency, solve the problem of easy displacement of decorative elements such as reflective strips during sewing, and improve sewing accuracy, this application provides a sewing auxiliary component.
[0005] To achieve the above objectives, this application provides a sewing auxiliary component, including a base and a presser foot body disposed on the base. The presser foot body surrounds a sewing hole, and a positioning component is disposed on the side of the presser foot body away from the sewing area. The positioning component includes a guide plate and a limiting plate. The limiting plate is disposed at the end of the presser foot body away from the connection between the two presser feet. The guide plate is detachably disposed on the side of the limiting plate away from the presser foot body. A guide channel is formed at the end of the guide plate near the connection between the two presser feet. The outlet of the guide channel faces the limiting plate. The limiting plate has a limiting opening that communicates with the sewing hole. A reflective strip passes sequentially through the guide channel, the limiting opening, and the sewing hole to abut against the sewing area. By adopting the above technical solution, the guide channel on the guide plate can guide the reflective strip, causing it to enter the limiting opening from the guide channel along a predetermined path and finally pass through the sewing hole to reach the sewing area. Because the outlet of the guide channel faces the limiting plate, this design ensures that the reflective strip accurately aligns with the limiting opening, avoiding positional deviations caused by improper operation. Simultaneously, the limiting opening on the limiting plate connects to the sewing hole, further restricting the movement trajectory of the reflective strip and improving its stability during transport. This allows the reflective strip to be fed more smoothly and accurately to the sewing area during sewing, effectively improving work efficiency and reducing the risk of material waste. Preferably, the limiting opening of the limiting plate is located between the two presser feet of the presser foot body. By adopting the above technical solution, placing the limiting opening between the two presser feet of the presser foot body effectively limits the positional deviation of the reflective strip. Since the limiting opening is located in the middle area of the two presser feet, this position is more stable than the sides, preventing lateral sliding or deviation from the predetermined path during transport. Furthermore, this design allows the reflective strip to more accurately align with the sewing hole when it enters the limiting opening through the guide channel, ensuring smooth transport of the reflective strip to the sewing area and maintaining good tension. Ultimately, this achieves the goal of improving sewing accuracy and work efficiency. Preferably, the extension line connecting the feed end and discharge end of the guide channel forms an angle of 15° to 75° with the worktable surface. By adopting the above technical solution, the angle between the extension line connecting the feed end and discharge end of the guide channel and the worktable surface is designed to be within the range of 15° to 75°. This angle design is carefully considered. First, it ensures that the reflective strip can obtain a suitable inclination when entering the guide channel, thereby reducing the phenomenon of material falling due to gravity and avoiding material jamming or deviation from the predetermined path. Second, this angle setting can also effectively guide the reflective strip to be transported from the guide channel to the limiting opening position in a stable state, further ensuring that the reflective strip accurately passes through the sewing hole and finally reaches the sewing area, improving the smoothness and accuracy of the overall sewing operation.Therefore, this specific angle limitation not only optimizes material transfer performance but also significantly improves the quality and efficiency of sewing. Preferably, the length of the guide channel is 'a', ranging from 1cm to 3cm. By adopting the above technical solution, setting the length of the guide channel within the range of 1cm to 3cm effectively balances operational convenience and positioning accuracy. When the guide channel is too short, the reflective strip is prone to deviating from the predetermined path, affecting the accuracy of subsequent sewing; while being too long increases material consumption and reduces assembly efficiency. Controlling the length within this range not only ensures the smooth introduction of the reflective strip and prevents it from deviating but also takes into account structural compactness and ease of use, thereby improving the overall quality and efficiency of sewing operations. Preferably, the limiting opening is elongated, and the width of the limiting opening is 'b', ranging from 0.5cm to 2cm. By adopting the above technical solution, the elongated design of the limiting opening effectively accommodates reflective strips of different widths, while limiting its width to the range of 0.5cm to 2cm ensures that the reflective strip can smoothly pass through the limiting opening and enter the sewing hole during the sewing process. This dimensional range is precisely calculated to ensure stable transmission of the reflective strip while avoiding positional shifts caused by an excessively wide opening or jamming caused by an excessively narrow opening, thereby improving the accuracy and efficiency of the sewing operation. Preferably, the limiting piece is provided with two reinforcing parts, each of which is respectively located on the presser foot of the presser foot body. The two reinforcing parts form a through hole, which communicates with the sewing hole. By adopting the above technical solution, the limiting piece is provided with two reinforcing parts located on the presser foot of the presser foot body. This not only enhances the structural stability between the limiting piece and the presser foot body but also effectively prevents deformation or displacement caused by uneven force during sewing. Since the two reinforcing parts together form a through hole, and this through hole communicates with the sewing hole, in actual use, this design further ensures a smooth and unobstructed path for the reflective strip as it passes through the limiting opening from the guide channel into the sewing hole, while maintaining the stability of the sewing area, thereby improving the operational accuracy and reliability of the entire device. Preferably, the inner wall of the guide channel is a smooth inner wall. By adopting the above technical solution, the inner wall of the guide channel is designed with a smooth surface, which can significantly reduce the friction between the reflective strip and the inner wall of the guide channel during the conveying process. This low-friction design helps ensure that the reflective strip is smoothly transferred from the feed end to the discharge end of the guide channel and accurately guided into the limiting opening and sewing hole, thereby avoiding jamming or damage caused by excessive friction. At the same time, the smooth inner wall can also improve the conveying stability of the reflective strip, further ensuring the efficiency and accuracy of the sewing operation. Preferably, the sewing auxiliary component also includes screws, and both the guide plate and the limiting plate are provided with screw holes. The screws pass through the screw holes of the guide plates in sequence and are detachably connected by the screws.This design allows the guide plate to be easily installed onto or removed from the limiting plate, enabling quick replacement of guide plates of different specifications according to varying sewing needs during actual use. The screw connection method offers high stability and reliability, ensuring the guide plate will not loosen or fall off during operation. This guarantees the reflective strip can be smoothly conveyed along the guide channel to the limiting opening and ultimately into the sewing hole for precise sewing. Furthermore, this simple structure is easy to manufacture and assemble, effectively reducing production costs and maintenance difficulty.
[0006] In summary, this application includes at least one of the following beneficial technical effects: 1. By setting a positioning component consisting of a guide plate and a limiting plate, the limiting opening of the limiting plate cooperates with the guiding channel of the guide plate to accurately guide the reflective strip to the position of the sewing area, preventing it from shifting during the sewing process, and significantly improving sewing accuracy and product quality; 2. The detachable guide plate design adapts to reflective strips of different sizes and types, eliminating the need to frequently replace the entire presser foot, reducing operational difficulty and time costs; Attached Figure Description Figure 1 This is a structural schematic diagram of a sewing auxiliary component in Embodiment 1.

[0008] The following is in conjunction with the appendix Figure 1 This application will be described in further detail.
[0009] This application discloses a sewing auxiliary component, referring to... Figure 1 It includes a base 1, a pressure needle body 2 disposed on the base 1, and a positioning component 3 disposed on the pressure needle body 2. The pressure needle body 2 is surrounded by a sewing hole for the free passage of a sewing needle.
[0010] Specifically, the positioning component 3 includes a limiting piece 31 and a guide piece 32 disposed on the pressing foot body 2. The limiting piece 31 is fixed at one end away from the connection between the two pressing feet. The guide piece 32 is installed on the limiting piece 31. Both the guide piece 32 and the limiting piece 31 are provided with screw holes 4. The guide piece 32 and the limiting piece 31 are screwed together by screws 5 to realize the detachable setting of the guide piece 32.
[0011] Specifically, the guide plate 32 has a smooth inner wall guide channel 321 at one end near the connection of the two presser feet. The limiting plate 31 has an elongated limiting opening 311, which is connected to the sewing hole of the presser foot body 2. The outlet of the guide channel 321 faces the limiting opening 311 of the limiting plate 31. When sewing the reflective strip, the reflective strip passes through the guide channel 321, the limiting opening 311, and the sewing hole in sequence, and then contacts the sewing area. The reflective strip is exposed at the sewing hole. The sewing needle passes through the sewing hole up and down to sew the reflective strip and the fabric in the sewing area.
[0012] In this embodiment, the width b of the limiting opening 311 is designed to range from 0.5cm to 2cm, allowing reflective strips of various widths to pass through. The length a of the guide channel 321 ranges from 1cm to 3cm. Within this range, the guide channel 321 not only ensures smooth insertion of the reflective strip and prevents it from shifting, but also takes into account the compact structure and ease of use. This is the optimal length designed for the size of the sewing machine used in this embodiment. In other embodiments, if the sewing machine is larger, the length of the guide channel 321 can be appropriately increased. The extension line of the connecting line between the feed end and the discharge end of the guide channel 321 forms an angle of 15° to 75° with the workbench surface, avoiding material jamming or deviation from the predetermined path.
[0013] Specifically, the limiting piece 31 is provided with two reinforcing parts 312, which abut against the two presser feet of the presser foot body 2. The two reinforcing parts 312 surround to form a through hole 313, which is located above the sewing hole and communicates with it. The limiting opening 311 is located between the sewing hole and the material outlet end of the guide channel 321. When sewing the reflective strip, the fabric is first placed on the sewing area of the table, the presser foot body 2 abuts against the fabric, and then the reflective strip is passed through the guide channel 321 and the limiting opening 311 in sequence and placed in the sewing area near the base 1, so that the reflective strip is exposed at the sewing hole. The sewing needle 4 moves up and down through the sewing hole to sew the reflective strip to the fabric.
[0014] In summary, by adding a double layer of protection with a guide plate 32 and a limiting plate 31 specifically designed for reflective strips, the cumulative effect of errors caused by human intervention is greatly reduced. The guide plate 32 is designed to guide the reflective strip to be conveyed in the correct direction, while the limiting plate 31 is correspondingly provided with a limiting opening 311 to quickly position the reflective strip below the sewing hole after it exits the guide channel 321. In addition, to accommodate reflective strips of different specifications, the guide plate 32 is provided with screw holes 4. The guide plate 32 is fastened by screws 5 passing through the screw holes 4, which facilitates the replacement of different models of guide plates 32 without the need for complex disassembly and assembly of the entire presser foot. When sewing reflective strips, the reflective strips are passed through the guide channel 321 and the limiting opening 311 in sequence to the bottom of the presser foot and abut against the sewing area. The reflective strips can be exposed through the through hole 313 on the limiting piece 31 and the sewing hole of the presser foot body 2. Then the sewing is started to sew the reflective strips and the fabric. The above structural design makes the sewing process simple and easy, which can improve the processing efficiency and solve the problem that reflective strips and other decorations are easy to shift during sewing.
[0015] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
