[0021] This application proposes a pleating presser foot, comprising: The presser foot handle 100 is used for fixed connection with the sewing machine, and the presser foot handle 100 is provided with a transverse through threaded hole; The presser foot plate 200 is rotatably connected to the bottom of the presser foot handle 100 at one end. The presser foot plate 200 is provided with at least two through holes 10 for needles to pass through. The at least two through holes 10 are spaced apart in the width direction of the pleating presser foot. Adjusting element 300 is threadedly engaged with threaded hole. One end of adjusting element 300 protrudes from threaded hole and abuts against presser foot plate 200 so as to drive presser foot plate 200 to swing during rotation. The first elastic element 400 elastically connects the presser foot handle 100 and the presser foot plate 200 so that the presser foot plate 200 elastically abuts against the adjusting element 300.

[0022] In the technical solution of this utility model, the first elastic member 400 ensures that the presser foot 200 is always in contact with the adjusting member 300. When the adjusting member 300 is rotated, it can drive the presser foot 200 to swing, thereby adjusting the tilt angle of the presser foot 200. During sewing, the shape of the pleats can be adjusted. In addition, the presser foot 200 is provided with two spaced holes 10 for the sewing needle to pass through. This allows a double-needle sewing machine to sew two pleats at the same time, ensuring that the spacing and uniformity of the pleats are consistent. When processing the collar of sweaters, dresses, etc. with pleats, the sewing speed can be increased, and the finished product has a delicate appearance and a uniform pleat feel.

[0023] like Figures 1 to 4In one embodiment of this application, the pleating presser foot includes a presser foot handle 100, a presser foot plate 200, an adjusting member 300, and a first elastic member 400. The presser foot handle 100 and the presser foot plate 200 are made of metal, with a fixed structure at the top for connection to a sewing machine and a transversely penetrating threaded hole at the bottom. The presser foot handle 100 serves as the mounting reference for the overall structure, providing support for other components. The presser foot plate 200 is flat, with one end rotatably connected to the bottom of the presser foot handle 100 via a pivot. Specifically, the presser foot plate 200 can be a metal plate with a bending structure. The presser foot plate 200 has two through holes 10, spaced apart along the width of the presser foot. The through holes 10 allow the sewing machine needle to pass through during sewing, and the two through holes allow the sewing machine to operate with two needles simultaneously. The adjusting element 300 can be a bolt structure. It engages with a threaded hole on the presser foot handle 100, with one end extending beyond the threaded hole and abutting against the side of the presser foot plate 200. The adjusting element 300 can convert rotational motion into axial displacement, causing the presser foot plate 200 to change angle. The first elastic element 400 is a compression spring, with one end fixed to the bottom of the presser foot handle 100 and the other end connected to the presser foot plate 200. The first elastic element 400 can be a coil spring or a spring sheet structure. It ensures that the presser foot plate 200 and the adjusting element 300 are always in contact, maintaining the stability of the presser foot plate 200's angle. In use, the presser foot handle 100 is mounted on the sewing machine. By rotating the adjusting member 300, it moves within the threaded hole, thereby pushing the presser foot plate 200 to rotate around its rotatable connection with the presser foot handle 100. This changes the tilt angle of the presser foot plate 200, thus controlling the thickness of each pleat. During this process, the first elastic member 400 constantly pushes the presser foot plate 200 upwards, keeping it in contact with the adjusting member 300. During sewing, two sewing needles pass through the two through holes on the presser foot plate 200, simultaneously forming two parallel pleats on the fabric. This not only ensures consistent spacing between the two pleats, eliminating dimensional deviations caused by secondary sewing in traditional processes, but also improves sewing efficiency.

[0024] like Figure 2 A specific structural design of the presser foot handle 100 is shown. In this design, the presser foot handle 100 includes a connecting rod 110. The connecting rod 110 has a first connecting part 111 and a second connecting part 112 that are bent and connected. The first connecting part 111 is used to connect with a sewing machine, and a threaded hole is provided on the first connecting part 111. The second connecting part 112 is used to hinge with the presser foot plate 200. A first elastic member 400 connects the second connecting part 112 and the presser foot plate 200.

[0025] The presser foot handle 100 includes a connecting rod 110, which has a first connecting part 111 and a second connecting part 112 connected by bending. The included angle between the first connecting part 111 and the second connecting part 112 can be set to 90 degrees or other arbitrary angles as required. To ensure structural strength, the connecting rod 110 can be integrally formed. The first connecting part 111 is used to connect with a sewing machine, and a threaded hole is provided on the first connecting part 111. The threaded hole can be located on the first connecting part 111 near the second connecting part 112, and its diameter can be... The adjustment component 300 is matched to the dimensions of the adjustment component 300. The end of the second connecting part 112 away from the first connecting part 111 is hinged to the presser foot plate 200, specifically via a pin. The first elastic element 400 connects the second connecting part 112 and the presser foot plate 200. The first elastic element 400 can be a common compression spring. The first elastic element 400 can be clamped between the second connecting part 112 and the presser foot plate 200. Under the action of the first elastic element 400, the presser foot plate 200 has an upward swing tendency and abuts against the adjustment component 300. Through the above technical solution, this solution improves the connection stability between the presser foot handle 100 and the presser foot plate 200. After the second connecting part 112 is bent away from the first connecting part 111, it provides the presser foot plate 200 with a larger swing space, increasing the swing angle range of the presser foot plate 200.

[0026] Figure 2 The specific structure of the presser foot plate 200 is also shown. In this scheme, the presser foot plate 200 includes a bent and connected pressing part 210 and an abutting part 220. The pressing part 210 is hinged to the second connecting part 112. The first elastic member 400 connects the pressing part 210 and the second connecting part 112. The abutting part 220 abuts against the adjusting member 300. The pressing part 210 can be designed as a flat plate structure, with one end of it hinged to the second connecting part 112 via a hinge shaft. The first abutting part 220 can be designed as an inclined plate structure at a certain angle to the pressing part 210, with its end face away from the pressing part 210 abutting the end of the adjusting member 300. The bending angle between the pressing part 210 and the abutting part 220 can be 90 degrees. The thrust applied by the adjusting member 300 acts directly on the abutting part 220, and the abutting part 220 drives the pressing part 210 to rotate around the hinge position, thereby realizing the functional zoning and force optimization of the presser foot plate 200 and reducing the overall force offset of the presser foot plate 200.

[0027] like Figure 2In another embodiment of this application, the abutment portion 220 is provided with an opening 221, and the pressing portion 210 is provided with two connecting bodies 211 spaced apart along the width direction. The two connecting bodies 211 are provided at two opposite edges of the opening 221, and the second connecting portion 112 passes through the opening 221 and is hinged to the two connecting bodies 211. The abutment portion 220 has a rectangular opening 221, the size of which is larger than that of the second connecting portion 112. The pressing portion 210 has two connecting bodies 211 spaced apart along its width. The two connecting bodies 211 can be integrally formed with the pressing portion 210 to ensure strength. The two connecting bodies 211 are located on two opposite sides of the opening 221. The second connecting portion 112 is designed to be able to pass through the opening 221. For example, it can be a flat rectangular block. After passing through the opening 221, its two sides are connected to the two connecting bodies 211 through hinge shafts to form a hinge structure. During the swinging process of the presser foot 200, the two connecting bodies 211 can disperse the force between themselves and the second connecting portion 112. In addition, the opening 221 also restricts the direction of swinging, reducing the shaking of the presser foot 200 and thus ensuring the quality of sewing. Through the above technical solution, this application simplifies the hinge structure between the presser foot plate 200 and the presser foot handle 100, and at the same time uses the opening 221 to ensure the stability of the swing trajectory of the presser foot plate 200, thus ensuring the sewing effect.

[0028] In another embodiment of this application, the outer peripheral wall of the adjusting member 300 is provided with a plurality of markers, which are spaced apart along the axial direction of the adjusting member 300. The markers can be scale lines or grooves, and can extend around the adjusting member 300. Each marker can be painted a different color. By observing the positional changes of these markers, the operator can intuitively judge the amount of rotation of the adjusting member 300, thereby accurately controlling the swing amplitude of the pressure foot plate 200 and improving the convenience and accuracy of the adjustment operation.

[0029] like Figure 2 and Figure 3 In another embodiment of this application, the presser foot handle 100 further includes a fixing post 120 for fixed connection with the sewing machine. The bottom of the fixing post 120 is provided with a guide hole, and a second elastic element 130 is disposed within the guide hole. The first connecting part 111 slides through the guide hole and is connected to the second elastic element 130. The fixing post 120 may be made of metal, and its top is fixed to the sewing machine table. The guide hole may be a shape adapted to the first connecting part 111, and its size is slightly larger than the outer perimeter of the first connecting part 111. The first connecting part 111 slides through the guide hole and can move along... Figure 3The presser foot 100 moves relative to the fixed column 120 in the vertical direction; the second elastic element 130 can be a compression spring, with one end fixed to the bottom of the fixed column 120 and the other end connected to the first connecting part 111. The elastic coefficient of the second elastic element 130 can be selected according to actual needs. During sewing, the first connecting part 111 can elastically abut against the sewn fabric, thus ensuring a stable connection between the presser foot handle 100 and the sewing machine, and realizing flexible buffering of the presser foot 200 during the sewing process. This effectively absorbs vibration or impact during the sewing process, avoids component wear or presser foot 200 swinging and shifting caused by rigid connection, and improves sewing quality.

[0030] like Figure 2 and Figure 3 In another embodiment of this application, a fixing hole is provided on the side of the fixing post 120, which communicates with the guide hole. The presser foot handle 100 also includes a fixing member 140, which is screwed into the fixing hole to fix or release the first connecting part 111. The fixing hole can be a circular hole, and its axis intersects perpendicularly with the axis of the guide hole. The presser foot handle 100 also includes the fixing member 140, which can be a bolt. The fixing member 140 is screwed into the fixing hole, and one end of the fixing member 140 can be provided with a groove to facilitate operation with tools. The other end of the fixing member 140 can be a flat head and can make close contact with the first connecting part 111. In use, the depth of the fixing member 140 inserted into the guide hole can be adjusted by rotating it. Specifically, when it is necessary to adjust the floating of the pressure foot plate 200, the fixing member 140 can be loosened, allowing the first connecting part 111 to slide within the guide hole, at which point the second elastic member 130 provides a buffering force; when floating is not required, the fixing member 140 can be tightened, fixing the first connecting part 111 in place. This structure allows users to flexibly adjust the state of the pressure foot plate 200 according to actual needs, improving the flexibility of use.

[0031] like Figure 4In another embodiment of this application, two presser foot plates 200, two adjusting members 300 and two first elastic members 400 are provided. The two presser foot plates 200 are spaced apart along the width direction. Each presser foot plate 200 is provided with a through hole 10. The two presser foot plates 200 are respectively hinged to the second connecting part 112. Each presser foot plate 200 is connected to the second connecting part 112 through a first elastic member 400. Each adjusting member 300 abuts against a presser foot plate 200. The two presser feet 200 are respectively connected to the second connecting part 112 through independent hinge shafts, forming a rotational engagement. Each presser foot 200 can rotate independently. In addition, a helical spring is provided between the pressing part 210 of each presser foot 200 and the second connecting part 112 as a first elastic element 400. Two adjusting screws are provided and screwed into the presser foot handle 100 respectively. The two adjusting screws abut against the two presser feet 200 one by one, so that the rotation angle of the two presser feet 200 can be independently controlled by the corresponding adjusting screws. Specifically, when the sewing machine is operating with two needles, by adjusting the angles of the two presser feet 200 respectively, when the angles of the two presser feet 200 are the same, two pleats with the same state can be sewn. When the angles of the two presser feet 200 are different, two pleats with different density can be sewn. That is to say, with the above structure, the operator can complete two different pleats simultaneously in a single sewing process, further improving the flexibility of use.

[0032] This utility model also proposes a sewing machine, which includes a machine body and a pleating presser foot disposed on the machine body. The specific structure of the pleating presser foot is as described in the above embodiments. Since all the technical solutions of the above embodiments are adopted, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.

[0033] 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.
