Description

Technical Field

[0001] The invention relates to a sewing machine presser foot and belongs to the technical field of sewing equipment. Background Art

[0002] The sewing machine presser foot is an indispensable part of the sewing process. It is located under the sewing machine needle and is mainly responsible for fixing the fabric flatly on the workbench to facilitate the formation of sewing stitches.

[0003] like Figure 1 As shown in the figure, the front end of the presser foot of a general sewing machine is split and slightly raised to facilitate the entry of fabric under the presser foot. However, when sewing fluffy materials such as cotton and silk floss, the material often gets caught, making it impossible to sew normally.

[0004] In the prior art, there is a solution of extending the presser foot forward and raising the front end height of the presser foot body to reduce hooking, and a pre-pressing device is also required for cooperation. Summary of the invention

[0005] In view of the above-mentioned defects of the prior art, the task of the present invention is to provide a sewing machine anti-hanging presser foot to solve the problem of hooking when sewing fluffy flocculent materials such as cotton and silk floss.

[0006] The technical solution of the present invention is as follows: a sewing machine anti-hanging presser foot, comprising a presser foot body and an anti-hanging component sleeved on the front end of the presser foot body, the anti-hanging component comprising a central connecting part and an outward extension part, the central connecting part is sleeved on the front end of the presser foot body and wraps the fork at the front end of the presser foot body, the outward extension part is connected to both sides of the central connecting part and warped upward, and the upper end spacing of the outward extension parts on both sides is greater than the lower end spacing.

[0007] Furthermore, the angle between the outwardly extending portion and the central connecting portion is no greater than 150°.

[0008] Furthermore, the anti-hanging component is made of a flexible material.

[0009] Furthermore, the anti-hanging component is made of cloth folded into multiple layers and bent to form the outward extension part, the outward extension parts on both sides are connected with connecting belts, a mounting rod is provided in the middle of the pressing foot body, and the connecting belt is connected to the mounting rod.

[0010] Furthermore, two ends of the connection belt are connected to the outwardly extending portions on both sides, and the connection belt is sleeved on the mounting rod.

[0011] Furthermore, the connecting belt is an elastic belt.

[0012] Furthermore, the multiple layers of fabric are folded to form an opening, and the slit at the front end of the pressed foot body is inserted into the opening.

[0013] Furthermore, the front end spacing of the outwardly extending portions on both sides is greater than the rear end spacing.

[0014] Furthermore, the corners of the outwardly extending portion are chamfered.

[0015] The advantages of the present invention compared with the prior art are: The invention wraps the fork at the front end of the press foot body with an anti-hanging part and forms a trapezoidal shape similar to a wide upper part and a narrow lower part, which can effectively prevent the front end of the press foot body from drilling into the gap of the fluffy material and prevent the fluffy material from hooking from both sides of the press foot body, so that the sewing of the fluffy material is smoother, each seam position is flat, and the material hooking and jamming will not cause the fabric to be twisted, thereby improving the quality of the product and making the product appearance flat and beautiful. At the same time, the front end of the press foot body does not need to be extended significantly, which can facilitate the pushing of the fabric and the observation of the actual working position of the press foot.

[0022] The present invention will be further described below in conjunction with the embodiments, but are not intended to limit the present invention.

[0023] Please combine Figures 1 to 4 As shown, a sewing machine anti-hanging presser foot involved in this embodiment includes a presser foot body 1 and an anti-hanging part 2 sleeved on the front end of the presser foot body 1. The presser foot body 1 is the same as the ordinary sewing machine presser foot body 1 used in the prior art, the front end of the presser foot body 1 has a fork, and the middle part of the presser foot body 1 has a mounting rod 3, and the presser foot body 1 can be installed on the sewing machine through the connection of the mounting rod 3.

[0024] The anti-hanging member 2 is made of a flexible material and has a two-fold three-section structure, which includes a central connecting portion 201 and an outward extension portion 202. The central connecting portion 201 is mounted on the front end of the pressing foot body 1 and wraps the fork at the front end of the pressing foot body 1. The outward extension portion 202 is connected to both sides of the central connecting portion 201 and warps upward. The upper end spacing of the outward extension portions 202 on both sides is greater than the lower end spacing. Figure 3 As shown. Specifically, there is an opening structure 203 on the rear side of the central connecting portion 201, and the fork at the front end of the press foot body 1 is inserted into the opening structure 203, and the original fork of the press foot body 1 is closed by the central connecting portion 201. The function of the outward extension portion 202 is to block the fluffy material on both sides of the press foot body 1 under the press foot, thereby preventing the fluffy material from moving from both sides of the press foot body 1 to the press foot body 1 and forming hooks. As a preferred embodiment, the front end spacing of the outward extension portions 202 on both sides is greater than the rear end spacing, as shown in FIG. Figure 4 As shown. Thus, the structure of the anti-hanging member 2 is a trapezoidal shape with a larger top and a smaller bottom when viewed from the main perspective, and a trapezoidal shape with a larger front and a smaller back when viewed from the top perspective. In addition, it is easy to understand that the corners of the outward extension portion 202 are chamfered to further reduce the possibility of hooking.

[0025] Further integration Figure 5 and Figure 6 As shown, in a preferred embodiment, the anti-hanging component 2 is made of a rectangular cloth of 4.5 cm in length and 4 cm in width, folded into multiple layers and radially bent at both ends to form an outward extension portion 202, with a central connecting portion 201 in the middle. A connecting belt 205 is connected to the outward extension portions 202 on both sides. Specifically, an elastic belt is used as the connecting belt 205, one end of the connecting belt 205 extends from the rear edge of one outward extension portion 202 and is sewn and connected, and the other end of the connecting belt 205 extends from the rear edge of the other outward extension portion 202 and is sewn and connected. The multiple layers of cloth are folded to form an opening 204. During installation, the fork at the front end of the pressing foot body 1 is inserted into the opening 204, and the connecting belt 205 is put on the installation rod 3, that is, the connecting belt 205 is tied to the rear side of the installation rod 3. In this way, the anti-hanging component 2 of the cloth can also easily maintain the bent and raised shape of the outward extension portion 202, so that the angle between the outward extension portion 202 and the central connecting portion 201 is not greater than 150°. When sewing fluffy materials such as cotton and wool fabrics, the sewing machine anti-hanging presser foot of the present invention can prevent the presser foot from hooking the materials during the sewing process, and the anti-hanging part 2 can be directly mounted on the original presser foot, which can save time for replacing the presser foot.
