Description

Technical Field

[0001] This utility model relates to the technical field of sewing auxiliary tools, and in particular to a template for sewing decorative lines on a placket. Background Technology

[0002] As the garment manufacturing industry continues to demand higher production quality and craftsmanship, the trend towards automation in garment production is becoming increasingly apparent. To meet the high standards of quality and detail required in mass production, a series of sewing templates specifically designed for different production processes have emerged within the garment industry. Among these templates, sewing templates, as a highly practical auxiliary tool, are widely used in the production process to automate the production of placket structures. Especially in the stage of sewing decorative lines on the placket, these templates play a crucial role in ensuring the neatness and aesthetics of the decorative lines while simultaneously improving production efficiency.

[0003] Chinese Patent CN215209930U discloses a placket sewing template, including a base plate, a cover plate, and a first pressure plate. The base plate has a placket forming area and a covering surface, with the placket forming area at least partially located within the covering surface. A first sewing positioning groove penetrating the thickness direction of the base plate is provided on the placket forming area. The cover plate is foldably connected to the base plate and has a second sewing positioning groove penetrating the thickness direction of the cover plate. When the cover plate is folded over and covers the covering surface, it at least partially covers the placket forming area, and the second sewing positioning groove coincides with and communicates with the first sewing positioning groove. The first pressure plate is foldably connected to the base plate. When the first pressure plate is folded over and covers the base plate, it at least partially presses against the position within the placket forming area where the first sewing positioning groove is not provided. By setting the first pressure plate, the fabric piece can be surrounded by the first pressure plate to form the shape of the placket, thereby achieving one-time sewing of the placket and effectively simplifying the placket sewing process.

[0004] The existing technical solutions described above have the following drawbacks: In the actual application of the placket sewing template, since the placket patch requires the two pieces to be sewn together on one side before the decorative stitching is done, the connecting side of the placket patch has four layers of fabric thickness, while the other side only has two layers. When the placket patch is placed and ready for sewing, the thinner side of the template cover plate will lift up as a whole. In this case, the template can only effectively press down the thicker side of the placket patch, but cannot firmly press down the thinner side, causing the fabric pieces to loosen and shift during the sewing process, affecting the sewing quality. Utility Model Content

[0005] The present invention addresses the aforementioned shortcomings in the prior art by providing a decorative stitching template for placket patches. By designing the cover plate as a split structure, which covers and presses the placket patch from both sides of the base plate, it effectively solves the problem of the cover plate lifting and failing to press the patch tightly due to uneven thickness of the cut pieces, thus improving sewing quality.

[0006] The above-mentioned utility model objective is achieved through the following technical solution:

[0007] A template for sewing decorative lines on a placket includes a base plate, a placket limiting portion disposed on the base plate, a first sewing positioning groove formed on the base plate, two rotatable separate cover plates mounted on opposite sides of the base plate, and a positioning edge formed on one side of the separate cover plates. The placket limiting portion is arranged opposite at least two adjacent sides of the placket patch. The first sewing positioning groove is arranged with a gap relative to the decorative lines on the placket patch. After the two separate cover plates are flipped towards each other and overlapped on the base plate, a second sewing positioning groove is formed between the two positioning edges, which coincides with the first sewing positioning groove.

[0008] By adopting the above technical solution, before sewing, one side of the two pieces is sewn together to obtain a placket patch. The placket patch is then laid flat on the base plate, and at least two adjacent sides, i.e., at least one corner, of the placket patch abut against the placket limiting part to complete the initial positioning. Then, the two separate cover plates are flipped in opposite directions and overlapped on the base plate and the placket patch. Since the two separate cover plates overlap the thicker side (piece connection side) and the thinner side (non-piece connection side) of the placket patch respectively, the two positioning edges are prevented from lifting relative to the placket patch, and the placket patch can be pressed tightly on both sides. Furthermore, the orthographic projection of the two positioning edges in the vertical direction coincides with the opposite sides of the first sewing positioning groove, thus forming a second sewing positioning groove that coincides with the first sewing positioning groove. Then, the template with the placket patch is sent to the sewing machine for sewing, which works along the first and second sewing positioning grooves to obtain a placket patch with decorative lines.

[0009] The present invention is further configured to include at least two sewing limit portions disposed on the base plate, wherein the at least two sewing limit portions are sequentially abutted against the starting end of the first sewing positioning groove along the sewing direction.

[0010] By adopting the above technical solution, the starting sewing position of the placket patch can be precisely controlled during the sewing process, ensuring that the starting point of the decorative line is consistent with the predetermined position of the placket patch. In addition, the setting of the sewing limit part can also prevent the placket patch from shifting during sewing, thereby ensuring the continuity and uniformity of the decorative line. In practical applications, this design greatly improves the accuracy and efficiency of sewing the decorative line of the placket patch, while reducing the scrap rate caused by improper operation.

[0011] The present invention is further configured such that the placket limiting part and the sewing limiting part are adhered to the base plate.

[0012] By adopting the above technical solution, disassembly and replacement are facilitated.

[0013] The present invention is further configured such that the placket limiting part is configured as an L-shape or a U-shape.

[0014] By adopting the above technical solution, the placket limiting part can effectively surround the edge of the placket patch, allowing the placket patch to be more stably fixed on the template during sewing, preventing displacement during the sewing process, and ensuring that the edge of the placket patch does not curl up or flip during sewing, thus guaranteeing the neatness and aesthetics of the decorative line. Furthermore, this design facilitates quick positioning of the placket patch by the operator, improving work efficiency. In actual production, this placket limiting part design significantly reduces the skill requirements for operators, allowing even less experienced workers to quickly get started, ensuring production consistency and quality.

[0015] The present invention is further configured such that the placket limiting part is arranged near the side of the cut piece connecting the placket patch.

[0016] By adopting the above technical solution, the connecting side of the placket patch is formed by bending and stitching the edges of two pieces together, resulting in a four-layer thickness. During the sewing process, the increased thickness can easily lead to uneven sewing or wrinkles. By arranging the placket limiting part close to the connecting side of the placket patch, the sewing depth and pressure of this part can be effectively controlled, ensuring uniformity and flatness during the sewing process. In addition, this design can reduce sewing deviations caused by uneven piece thickness, thereby improving the overall aesthetics of the decorative lines. In practical applications, this setting of the placket limiting part significantly improves the sewing quality of the decorative lines on the placket patch, while reducing the dependence on the precision of the sewing equipment, making the production process more stable and reliable.

[0017] The present invention is further configured such that: the placket limiting part is arranged close to one of the split cover plates, and the L-shaped or U-shaped openings are sequentially facing the first sewing positioning groove and the other split cover plate.

[0018] By adopting the above technical solution, the contact area between the thinner side of the placket (the side not connected to the cut piece) and the other separate cover plate can be increased, so as to better press and fix the placket.

[0019] The present invention is further configured such that an adjustment port is provided on one side of the base plate and the other split cover plate that are close to each other.

[0020] By adopting the above technical solution, since both the base plate and the cover plate are flexible sheets, the design of the adjustment port allows the base plate and another separate cover plate to be flexibly fine-tuned according to the actual thickness of the placket, thereby achieving more precise positioning. This adjustment mechanism ensures that the template can adapt to and maintain the consistency of sewing quality when plackets of different thicknesses are used.

[0021] The present invention is further provided with a connecting sticker between the surfaces of the base plate and the split cover plate.

[0022] By adopting the above technical solution, disassembly and replacement are facilitated.

[0023] In summary, the beneficial technical effects of this utility model are as follows: This utility model achieves precise sewing of decorative lines on placket patches, improving production efficiency and product quality. During the sewing process, the two adjacent sides of the placket patch are limited by the placket limiting part, ensuring the accuracy of the placket patch installation on the template. At the same time, the design of the split cover plate ensures that the placket patch is subjected to uniform pressure during sewing, avoiding displacement problems caused by uneven pressure. In addition, the combined use of the first and second sewing positioning grooves makes the sewing position of the decorative line more precise and the decorative effect more beautiful. Finally, this utility model provides a placket patch sewing template that is easy to operate, accurately positioned, and has a good decorative effect, suitable for sewing decorative lines on placket patches in various garment production processes.

Detailed Implementation

[0027] To make the technical means, creative features, objectives and effects of this utility model clearer and easier to understand, the present utility model will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0028] Reference Figure 1This utility model discloses a placket decorative line sewing template, which includes a base plate 1, a placket limiting part 2 and two sewing limiting parts 3 adhered to the base plate 1, a first sewing positioning groove 4 opened on the base plate 1, two separate cover plates 5 respectively arranged on opposite sides of the base plate 1, a connecting sticker 6 set between the surfaces of the base plate 1 and the separate cover plates 5, and a positioning edge 7 opened on one side of the separate cover plates 5.

[0029] The placket limiting part 2 is L-shaped and arranged opposite the connecting side of the placket patch and its adjacent sides. The placket limiting part 2 is located near one of the split cover plates 5, and the L-shaped opening faces the first sewing positioning groove 4 and the other split cover plate 5 sequentially. The placket limiting part 2 effectively surrounds the edge of the placket patch, allowing it to be more stably fixed to the template during sewing, preventing displacement and ensuring that the edge of the placket patch does not curl or flip during sewing, thus guaranteeing the neatness and aesthetics of the decorative lines. Furthermore, this design facilitates quick positioning of the placket patch by the operator, improving work efficiency. In actual production, this design of the placket limiting part 2 significantly reduces the skill requirements for operators, allowing even less experienced workers to quickly get started, ensuring production consistency and quality.

[0030] The connecting side of the placket patch is formed by bending and stitching the edges of two pieces together, resulting in a four-layer thickness. During sewing, the increased thickness can easily lead to uneven stitching or wrinkles. By arranging the placket limiting part 2 close to the connecting side of the placket patch, the sewing depth and pressure of this part can be effectively controlled, ensuring uniformity and flatness during the sewing process. In addition, this design can reduce sewing deviations caused by uneven piece thickness, thereby improving the overall aesthetics of the decorative lines. In practical applications, this setting of the placket limiting part 2 significantly improves the sewing quality of the decorative lines on the placket patch, while reducing the dependence on the precision of the sewing equipment, making the production process more stable and reliable.

[0031] Two sewing limiters 3 are sequentially abutted against the starting end of the first sewing positioning groove 4 along the sewing direction. The sewing limiters 3 enable precise control of the starting sewing position of the placket patch during the sewing process, ensuring that the starting point of the decorative line is consistent with the predetermined position of the placket patch. In addition, the sewing limiters 3 also prevent the placket patch from shifting during sewing, thereby ensuring the continuity and uniformity of the decorative line. In practical applications, this design greatly improves the accuracy and efficiency of sewing the decorative line of the placket patch, while reducing the scrap rate caused by improper operation.

[0032] Reference Figure 2The first sewing positioning groove 4 is arranged with a gap relative to the decorative line of the placket. The two split cover plates 5 are flipped in opposite directions and overlapped with the bottom plate 1. The two positioning edges 7 form a second sewing positioning groove 8 that coincides with the first sewing positioning groove 4. Before sewing, one side of the two pieces of fabric is sewn together to form a placket patch. The placket patch is then laid flat on the base plate 1, and at least two adjacent sides, i.e. at least one corner, of the placket patch abut against the placket limiting part 2 to complete the initial positioning. Then, the two separate cover plates 5 are flipped in opposite directions and overlapped on the base plate 1 and the placket patch. Since the two separate cover plates 5 overlap the thicker side (the side where the pieces are connected) and the thinner side (the side where the pieces are not connected) of the placket patch respectively, the two positioning edges 7 are prevented from lifting relative to the placket patch, and the placket patch can be pressed tightly on both sides. The orthographic projection of the two positioning edges 7 in the vertical direction coincides with the opposite sides of the first sewing positioning groove 4, thus forming the second sewing positioning groove 8 that coincides with the first sewing positioning groove 4. Then, the template with the placket patch is sent to the sewing machine for sewing. It works along the first sewing positioning groove 4 and the second sewing positioning groove 8 to obtain a placket patch with decorative lines.

[0033] Reference Figure 1 The base plate 1 and the other split cover plate 5 are fitted with adjustment ports 9 on their adjacent sides. Since both the base plate 1 and the cover plate are flexible sheets, the design of the adjustment ports 9 allows the base plate 1 and the other split cover plate 5 to be flexibly fine-tuned according to the actual thickness of the placket, thereby achieving more precise positioning. This adjustment mechanism ensures that the template can adapt to and maintain the consistency of sewing quality when plackets of different thicknesses are used.

[0034] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
