Description

Technical Field

[0001] This utility model relates to the field of sewing machine accessories technology, specifically to a tool for assisting in cutting the stop edge. Background Technology

[0002] In garment making, especially in haute couture, to reduce seam thickness and ensure a smooth seam after sewing two layers of fabric, particularly in areas requiring folding, a layered trimming method is used. This involves cutting the edges of the two sewn layers into different widths; for example, the inner seam allowance is trimmed narrower than the outer layer. This prevents the seam from appearing bulky after folding, maintaining a smooth finish. The common practice is to sew first and then trim by hand. This method not only increases labor costs but also, due to uneven pressure control during manual operation, easily leads to uneven cutting of the lower layer or accidental cutting of the upper layer, affecting the quality of the finished product. Therefore, further improvements are needed. Utility Model Content

[0003] This utility model addresses the shortcomings of existing technologies by providing an auxiliary tool for cutting the stop, thereby solving the problems mentioned in the background art, such as increased labor costs due to sewing before manual trimming and uneven application of manual operation force leading to uneven cutting of the lower layer or accidental cutting of the upper layer fabric.

[0004] To achieve the above technical objectives, this utility model proposes the following technical solution: a tool for assisting in cutting the stop edge, including a presser foot, a cutting knife, and a cutting rod. One end of the cutting rod is provided with a U-shaped positioning component, which is fixed to the sewing machine worktable by a mounting component. The presser foot and the cutting knife are installed below the sewing machine and located on both sides of the cutting rod. A guide component is provided on the side of the cutting rod near the presser foot along the length direction of the cutting rod.

[0005] Furthermore, a guide plate is provided on the side away from the cutting bar along the fabric travel direction, and the guide plate is installed on the sewing machine's worktable.

[0006] Furthermore, the mounting component includes a mounting base, and a guide groove adapted to the U-shaped positioning component is provided on one side of the mounting base.

[0007] Furthermore, the mounting component includes a mounting base, and a guide groove adapted to the U-shaped positioning component is provided on one side of the mounting base.

[0008] Furthermore, the mounting base has a through mounting hole on its upper part for fixing it to the sewing machine workbench, and a fastening screw is provided in the mounting hole.

[0009] Compared with the prior art, the beneficial effects of this utility model are as follows: This utility model uses a cutting rod, a guide, and a sewing machine presser foot and cutting knife to separate the upper and lower layers of fabric and cut the lower layer of fabric in the double-layer fabric. In one process, it can produce edge edges of different widths. Compared with the traditional operation method, it not only reduces labor costs but also improves work efficiency. It is also more convenient to install and use. Attached Figure Description

[0014] The following are specific embodiments of the present invention, and the technical solution of the present invention will be further described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0015] like Figure 1-3 As shown, this utility model provides a tool for assisting in cutting the stop edge, including a presser foot 1, a cutting knife 2, and a cutting rod 3. A U-shaped positioning component 4 is fixedly provided at one end of the cutting rod 3. The U-shaped positioning component 4 is fixed to the sewing machine worktable by a mounting component 5. The presser foot 1 and the cutting knife 2 are installed below the sewing machine and located on both sides of the cutting rod 3. A guide component 6 is provided on the side of the cutting rod 3 near the presser foot 1 along the length direction of the cutting rod 3.

[0016] like Figure 1 and Figure 2As shown, the presser foot 1 is a single-sided presser foot. The U-shaped positioning piece 4 is fixed to the sewing machine worktable under the action of the mounting piece 5 to fix the cutting rod 3. The guide piece 6 has an arc-shaped cross-section to guide the upper layer of fabric and prevent the upper layer of fabric from passing through the cutting rod 3. In use, the upper layer of fabric 9 of the double-layer fabric is placed in the guide piece 6. The guide piece 6 isolates the upper layer of fabric 9. The presser foot 1 of the sewing machine is lifted, and the lower layer of fabric 10 is passed through the cutting rod 3. Then the presser foot 1 is lowered, and the presser foot 1 will press the fabric tightly. The cutting blade 2 of the sewing machine is located on one side of the cutting rod 3 to cut the lower layer of fabric. At the same time, the needle 8 of the sewing machine is located at one end of the guide piece 6 to sew the double-layer fabric together. Compared with the traditional operation method, it can not only realize the simultaneous sewing and cutting, but also avoid cutting the upper layer of fabric 9, reduce labor costs and improve production efficiency.

[0017] A guide plate 7 is provided on the side away from the cutting rod 3 along the fabric travel direction, and the guide plate 7 is installed on the sewing machine worktable.

[0018] like Figure 1 As shown, the guide plate 7 has an L-shaped structure and is installed on the sewing machine's worktable by adjusting screws. It can guide the direction of the lower layer of fabric. The distance between the guide plate 7 and the cutting rod 3 can be adjusted according to the width of the lower layer of fabric 10 to be cut.

[0019] The U-shaped positioning component 4 and the cutting rod 3 are designed as an integral part of bent iron wire.

[0020] like Figure 3 As shown, iron wire is readily available, reducing processing difficulty.

[0021] The mounting component 5 includes a mounting base 51. A guide groove 52 adapted to the U-shaped positioning component 4 is provided on one side of the mounting base 51. A mounting hole 53 is provided above the mounting base 51 to fix the mounting to the sewing machine workbench. A fastening screw 54 is provided in the mounting hole 53.

[0022] like Figure 2 and Figure 3 As shown, the U-shaped positioning piece 4 is inserted into the guide groove 52. By adjusting the depth of the U-shaped positioning piece 4 inserted into the guide groove 52, the horizontal distance between the cutting rod 3 and the cutting blade 2 can be adjusted, thereby adjusting the width of the stop. After the U-shaped positioning piece 4 is inserted into the guide groove 52, the fastening screw 54 is screwed into the mounting hole 53, so that the mounting base 51 is fixed on the sewing machine's worktable. The U-shaped positioning piece 4 is fixed in the guide groove 52 under the pressure of the fastening screw 54. After loosening the fastening screw 54, the horizontal distance between the cutting rod 3 and the cutting blade 2 can be easily adjusted by pushing or pulling out the cutting rod 3 and the U-shaped positioning piece 4.

[0023] Operating principle: First, fix the cutting rod 3 on the sewing machine worktable. Specifically, insert the U-shaped positioning piece 4 into the guide groove 52, and then insert the fastening screw 54 into the mounting hole 53. Adjust the depth of the U-shaped positioning piece 4 into the guide groove 52 according to the required cutting width. Then fix the mounting base 51 and the U-shaped positioning piece 4 together on the sewing machine worktable.

[0024] During cutting, bring the cutting edge of the double-layered fabric close to the cutting blade 2 of the sewing machine so that the edge of the upper fabric 9 enters the guide 6. Raise the presser foot 1 of the sewing machine, pass the lower fabric 10 through the cutting bar 3 and align it with the guide plate 7, and then lower the presser foot 1. The presser foot 1 will press the fabric tightly, and the cutting blade 2 on one side of the cutting bar 3 will cut the lower fabric 10. At the same time, the upper fabric 9 passes through the guide 6 and is sewn to the lower fabric 10.

[0025] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to replace them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.
