[0029] During the process of sewing topstitching and covering seams, the fabric is prone to shifting due to its smoothness or thinness, causing it to twist and wrinkle, which affects the appearance and quality of the garment.

[0030] This utility model proposes a sewing auxiliary tool.

[0031] Please see Figure 1 and Figure 2 In one embodiment of this utility model, the sewing auxiliary tool 100 includes:

[0032] Positioning plate 1 extends along the seam direction of the target piece, is positioned on the upper surface of the target piece and abuts against the presser foot of the sewing machine, such that two opposite sides of positioning plate 1 contact the target piece and the presser foot respectively; and

[0033] The flattening component 2 is rotatably positioned on one side of the positioning plate 1 and is used to flatten the target component before the stitching.

[0034] The technical solution of this utility model, through the cooperation of the positioning plate 1 and the presser foot on the sewing machine, ensures the precise positioning of the target part during the sewing process, reducing dimensional errors caused by fabric movement or stretching. During sewing, the target part (the fabric to be sewn) is placed on the sewing machine's worktable, and the positioning plate 1 is placed on the upper surface of the target part, ensuring that the positioning plate 1 is correctly aligned along the seam direction and abuts against the presser foot of the sewing machine. During sewing, the positioning plate 1 and the fabric move synchronously. For fabrics that are too thin or too soft, with the support of the positioning plate 1, the fabric can also be moved by the user along the seam direction, ensuring accurate dimensions during sewing. Furthermore, to ensure the flatness of the fabric, the target part can be flattened before sewing using the flattening device 2, reducing fabric movement and wrinkles, thus improving the consistency and aesthetics of the finished product.

[0035] Specifically, the shape of the positioning plate 1 is not specifically limited. For example, it can be rectangular, trapezoidal, or elliptical, or it can be L-shaped, T-shaped, or other irregular shapes, as long as the shape is suitable for the seam position of the target piece. In this embodiment, the size and material of the positioning plate 1 are not specifically limited, as long as it can cooperate with the fabric and play the role of supporting and positioning the fabric. The flattening component 2 can be a weighted roller or an ironing board with a heating function. It applies physical pressure or heat to the fabric to make it flat and helps to eliminate wrinkles in the fabric. The flattening component 2 is located on the side of the positioning plate 1 and does not affect the contact and positioning between the positioning plate 1 and the fabric, or between the positioning plate 1 and the presser foot. In actual use, the positioning plate 1 can be stood up first so that the flattening component 2 can contact the fabric to flatten the fabric before sewing; then the positioning plate 1 can be laid flat on top of the fabric and abut against the presser foot to assist in completing the sewing work.

[0036] In the embodiments of this utility model, please refer to Figure 2 The positioning plate 1 has a mounting groove 11, and a support shaft 12 is provided inside the mounting groove 11, extending through its opening. The flattening component 2 is a rolling ball, which is rotatably fitted around the outer periphery of the support shaft 12. The mounting groove 11 extends along the seam direction of the target part and is used to accommodate the support shaft 12. For example, the mounting groove 11 can be designed as rectangular or circular to accommodate support shafts 12 of different shapes. The support shaft 12 is fixed to the positioning plate 1 and is used to support the flattening component 2 (rolling ball). The rolling ball, which can be a steel ball or a plastic ball, is rotatably fitted around the outer periphery of the support shaft 12. Its surface can be smooth or textured to increase friction, and the diameter of the rolling ball can be adjusted according to the thickness of the target part and the required pressure. The rolling ball moves along the support shaft 12, which can flatten the target part before sewing. The movement of the rolling ball can be manual or driven by a motor. For example, a manual knob or lever can be designed on the side of the positioning plate 1, which the operator can rotate or push to control the rotation of the rolling ball.

[0037] In the embodiments of this utility model, please refer to Figure 2Multiple rolling balls are spaced at intervals and are evenly distributed on one side surface of the positioning plate 1. The rolling balls can be fixed to the positioning plate 1 using bearings or an embedded design. For example, the rolling balls can be partially embedded in the mounting groove 11 on the surface of the positioning plate 1, or mounted in the mounting groove 11 on the positioning plate 1 via bearings, allowing them to rotate freely. The multiple rolling balls are evenly distributed on one side surface of the positioning plate 1; for example, one rolling ball can be placed every 2 centimeters. The specific spacing can be adjusted according to the width of the fabric and the stitch length of the sewing machine to ensure uniform pressure is applied to the target material during sewing, reducing unevenness and wrinkles in the fabric. The size of the rolling balls can be adjusted according to the thickness of the fabric and the required pressure. For example, for thin fabrics, smaller diameter rolling balls can be selected, while for thick fabrics, larger diameter rolling balls are needed to provide sufficient pressure.

[0038] In the embodiments of this utility model, please refer to Figure 1 The positioning plate 1 has scale lines 13 located on the edge of the positioning plate 1 near the presser foot and on the surface of the positioning plate 1 facing away from the target part. This allows the operator to clearly see the scale lines 13 during sewing, serving as a sewing reference. For example, the scale lines 13 can be a series of equidistant straight lines, each spaced 1 cm or 0.5 inch apart, or they can be a standard ruler with a graduation of 1 mm to accommodate different sewing needs. The scale lines 13 on the positioning plate 1 provide an intuitive visual reference and allow for real-time observation of the thread size, enabling the operator to more accurately align the thread and improve sewing precision.

[0039] In the embodiments of this utility model, please refer to Figure 4 The positioning plate 1 has a length ranging from 15 to 30 cm, a width ranging from 3 to 5 cm, and a thickness ranging from 1 to 3 cm. These dimensions cover most everyday sewing needs, from small repairs to large garment projects; they also do not occupy much workbench space and do not interfere with normal sewing operations. The length, width, and thickness of the positioning plate 1 can be designed according to specific needs, allowing the tool to adapt to different sizes and shapes of workpieces, thus providing a wider range of applications.

[0040] In the embodiments of this utility model, please refer to Figure 1 and Figure 3The sewing auxiliary tool 100 also includes a shaped presser plate 3, which is rotatably configured with the positioning plate 1. This allows the shaped presser plate 3 to have an unfolded state (rotating away from the positioning plate 1) and a folded state (overlapping with the positioning plate 1). The edge of the shaped presser plate 3 has an arc-shaped portion 31 for contacting the presser foot. The shaped presser plate 3 can be designed in different shapes, such as L-shaped, T-shaped, or S-shaped, to suit different sewing tasks. For example, for fabrics requiring sewing along curves, the shaped presser plate 3 can be designed with a corresponding curved shape. A hinge or rotating shaft can be provided between the shaped presser plate 3 and the positioning plate 1, allowing the shaped presser plate 3 to rotate above the positioning plate 1. For example, a metal hinge can be used, allowing the shaped presser plate 3 to rotate freely within a certain angle range. During sewing, the positioning plate 1 and the shaped presser plate can be unfolded first, and then one of them can be laid flat on the fabric, contacting both the fabric and the presser foot. It should be noted that a flattening component 2 can be provided on the left side of the positioning plate 1. After the irregularly shaped pressure plate 3 rotates, it is superimposed on the upper side of the positioning plate 1 to avoid the flattening component 2 and prevent the flattening component 2 from interfering with the rotation of the irregularly shaped pressure plate 3.

[0041] In the embodiments of this utility model, please refer to Figure 1 The curved portion 31 includes multiple concave portions 311 and multiple convex portions 312 with different curvatures, and the concave portions 311 and convex portions 312 are arranged adjacent to each other. The curved portion 31 can be designed as a series of continuous concave portions 311 and convex portions 312, and the curvature of each part can be customized according to common seam shapes. For example, the curved portion 31 can be designed as a wave-shaped or stepped shape to adapt to different sewing needs. For seams that require a soft curve, such as at the neckline, the concave portions 311 can be used to adapt to its shape; while for seams that need to keep the fabric flat, such as at the hem edge, the convex portions 312 can be used to support the fabric. For example, the curved portion 31 at the neckline can be designed as a deeper concave portion 311, while the curved portion 31 at the hem edge can be designed as a shallower convex portion 312.

[0042] In the embodiments of this utility model, please refer to Figure 1 and Figure 3 The sewing aid tool 100 also includes a damping shaft 4. Mounting holes 14 are provided on both the positioning plate 1 and the shaped pressure plate 3, with the damping shaft 4 passing through the mounting holes 14. The damping shaft 4 can be a slender metal rod or a plastic rod, its diameter and length determined according to the size and weight of the positioning plate 1 and the shaped pressure plate 3. For example, the damping shaft 4 can be a rod with a diameter of a few millimeters to one centimeter, and a length sufficient to pass through both mounting holes 14. The damping shaft 4 can be fixed in the mounting holes 14 by threads, slots, or fasteners to ensure it does not loosen during sewing. The damping shaft 4 allows the positioning plate 1 and the shaped pressure plate 3 to be fixed in different positions and angles, increasing the tool's adaptability and enabling it to be used for various sewing tasks.

[0043] In the embodiments of this utility model, please refer to Figure 4 The positioning plate 1 is provided with an anti-slip layer 15. The anti-slip layer 15 is provided on the side of the positioning plate 1 facing the target part and / or on the side of the positioning plate 1 facing away from the target part. That is, the anti-slip layer 15 can be provided on either the upper or lower side of the positioning plate 1, or on both sides, depending on actual needs. The anti-slip layer 15 can be made of rubber, silicone, or other materials with a high coefficient of friction to ensure effective anti-slip performance. For example, the anti-slip layer 15 can be designed with a textured or dotted surface to increase friction. The anti-slip layer 15 on the positioning plate 1 increases the friction between the positioning plate 1 and the fabric, allowing the fabric and the positioning plate 1 to move synchronously during sewing, preventing the fabric from slipping during sewing and improving sewing accuracy.

[0044] In embodiments of this invention, the anti-slip layer 15 is made of at least one of kerosene paper, an absorbent film, or a silicone pad. These three materials offer a variety of anti-slip effects and cost-effectiveness options to suit different sewing environments and needs. The specific choice depends on the required grip strength of the fabric. Keratin paper has good anti-slip properties and is environmentally friendly, providing stable fabric grip and is suitable for ordinary fabrics. The absorbent film provides strong adsorption and is suitable for smooth surfaces such as silk. The silicone pad has good elasticity and anti-slip properties and is suitable for fabrics requiring soft contact, such as silk.

[0045] In embodiments of this utility model, the positioning plate 1 is made of at least one of plastic, metal, fiberglass, wood, or rubber. The specific material chosen can be selected based on the user's actual needs. ABS plastic is lightweight, durable, and inexpensive, suitable for everyday household use. Metal positioning plates 1, such as aluminum alloy, are high-strength, sturdy, and durable, suitable for industrial sewing. Fiberglass positioning plates 1 have excellent strength and heat resistance, allowing for use in high-temperature sewing environments. Wooden positioning plates 1 offer good feel and aesthetics, and hardwood can be used to make positioning plates 1 for high-end sewing tools. Rubber positioning plates 1 have good elasticity and anti-slip properties, and natural rubber can be used to make positioning plates 1 that require soft contact.

[0046] In another embodiment, the mesh count of the positioning plate 1 ranges from 1000 to 3000 mesh, and the specific mesh count can be selected according to the fabric material. For example, for slippery and thin materials, a pressure plate with a smaller mesh count can be used. This is because a pressure plate with a smaller mesh count usually means that the holes on the pressure plate are larger, which allows for a larger contact area between the pressure plate and the fabric, thereby providing better grip and friction, helping to stabilize the fabric and reduce slippage during sewing. Of course, the choice of mesh count must also be determined in conjunction with the material of the positioning plate 1. A positioning plate 1 with a smaller mesh count and made of rubber or silicone can provide good protection for thin and easily damaged fabrics.

[0047] The above description is merely an exemplary embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
