[0034] During the sewing of fabric pieces and elastic bands, the elastic band's tension needs to be constantly controlled to prevent uneven stretching. This process requires manual adjustment, which is not only tedious but also makes it difficult to control the elastic band's tension, resulting in low overall sewing efficiency and poor quality.
[0035] Based on this, this application provides an elastic band sewing auxiliary device that can assist in controlling the tension of the elastic band. To more clearly illustrate the structure of the elastic band sewing auxiliary device, the following description will be provided in conjunction with the accompanying drawings.
[0036] For example, please see Figure 1 As shown, one embodiment of this application relates to an elastic band sewing auxiliary device. The elastic band sewing auxiliary device includes a main body and an elastic adjustment component and a sewing guide 200 connected to the main body. The elastic adjustment component is used to adjust the tension of the elastic band, and the sewing guide 200 is used to guide the elastic band after the elasticity is adjusted to a set sewing path. The elastic adjustment component includes a first guide rail 110 and a first limiting member 120 located on the first guide rail 110. The first limiting member 120 cooperates with the first guide rail 110 to form a first channel 410 for the elastic band to pass through. The height of the first channel 410 is adjustable.
[0037] The aforementioned elastic band sewing auxiliary device adjusts the tension of the elastic band by incorporating an elasticity adjustment component. Specifically, by adjusting the size of the first channel 410, different pressures are applied to the elastic band, thereby controlling the tension during sewing. Furthermore, the sewing guide 200 guides the adjusted elastic band onto a predetermined sewing path, eliminating the need for manual control of the elastic band's tension and achieving fast, high-quality elastic band sewing.
[0038] In some embodiments, the elastic adjustment component further includes a first shim. The first shim is attached to the first guide rail 110, and the height of the first channel 410 is adjusted by adjusting the height of the first shim.
[0039] In some embodiments, the first limiting member 120 includes two connecting ends perpendicular to the first guide rail 110 and a limiting head parallel to the first guide rail 110. The two ends of the limiting head are respectively connected to the two connecting ends, and the two connecting ends are respectively connected to the first guide rail 110. The first channel 410 is formed through the cooperation of the limiting head, the two connecting ends, and the first guide rail 110. Optionally, the first limiting member 120 has a "U"-shaped structure.
[0040] In some embodiments, the sewing guide 200 includes a second guide rail 210 and a second limiting member 220. The second limiting member 220 and the second guide rail 210 form a second channel 420 for the elastic band to pass through. Optionally, the structure of the second limiting member 220 is consistent with that of the first limiting member 120.
[0041] In some embodiments, the sewing guide 200 further includes a second shim. The second shim is attached to the second guide rail 210, and the height of the second channel 420 is adjusted by adjusting the height of the second shim. The main function of the second limiting member 220 is to guide the elastic band in the sewing direction and keep the elastic band flat during sewing, preventing the elastic band from spiraling. Therefore, the position of the second limiting member 220 is closer to the sewing position than the first limiting member 120. Optionally, the elastic band can be pressed by adjusting the relative distance between the second limiting member 220 and the second guide rail 210, thereby achieving tightness adjustment. However, since the position of the second limiting member 220 is closer to the sewing position than the first limiting member 120, the sewing position is closer to the deformation position, resulting in a shorter stretching deformation area of the elastic band. The local stretching degree is more easily affected by the sewing speed, which may lead to uneven sewing.
[0042] In some embodiments, a third limiting member 230 is further provided on the second guide rail 210, which cooperates with the second guide rail 210 to form a third channel 430 for the elastic band to pass through. Furthermore, the third limiting member 230 is closer to the seam than the first limiting member 120. Optionally, the third limiting member 230 may be closer to the seam than the second limiting member 220, or it may be farther away from the seam than the second limiting member 220. Optionally, the distance between the second limiting member 220 and the third limiting member 230 along the first guide rail 110 is 2cm to 15cm. Optionally, the distance between the second limiting member and the third limiting member 230 along the first guide rail 110 can be, but is not limited to, 2cm, 5cm, 7cm, 10cm, 13cm, 15cm, or other values within the range of 2cm to 15cm.
[0043] Please see Figure 2 , Figure 2This is another structural schematic diagram of the elastic band sewing auxiliary device according to one embodiment of this application, where x1 represents the initial direction of the elastic band when entering and adjusting its tension, and x2 represents the sewing method. When the direction of the elastic band needs to be significantly changed, such as deviating from the original direction by more than 45°, the second limiting member 220 and the third limiting member 230 can be set to jointly assist in guiding the elastic band, so as to avoid the problem of the elastic band rotating or folding itself when it deviates significantly.
[0044] In some embodiments, for the purpose of flattening the elastic band, a plurality of second limiting members 220 and a plurality of third limiting members 230 are provided on the second guide rail 210.
[0045] In some embodiments, the position of the first limiting member 120 on the first guide rail 110 is adjustable.
[0046] In some embodiments, a plurality of first limiting members 120 are provided on the first guide rail 110. Optionally, two sets of first limiting members 120 are provided on the first guide rail 110, and the distance between the two sets of first limiting members 120 along the direction of the first guide rail 110 is 3~20cm.
[0047] In some embodiments, the elastic band sewing aid further includes a first connector 310, which is connected to the main body, the elasticity adjustment component, and the sewing guide 200.
[0048] In some embodiments, the elastic adjustment component and the sewing guide 20 are fixedly connected to the first connector 310. Optionally, the fixed connection can be achieved by welding.
[0049] In some embodiments, the first connector 310 is provided with a mounting hole 311, and the elastic adjustment component is mounted at the mounting hole 311 via a first fastener. Optionally, the first fastener includes a nut.
[0050] In some embodiments, the mounting position of the elastic adjustment component on the mounting hole 311 is adjustable.
[0051] In some embodiments, the sewing guide 200 is mounted at the mounting hole 311 via a second fastener. Optionally, the second fastener includes a nut.
[0052] In some embodiments, the mounting hole 311 is an elongated mounting hole 311; the mounting position of the sewing guide 200 on the mounting hole 311 is adjustable.
[0053] In some embodiments, the first connector 310 is rotatably connected to the main body. Optionally, the main body has a first through hole, and the first connector 310 has a second through hole. A fastener 312 passes through the first through hole and the second through hole to fix the main body to the first connector 310. Before fastening, the angle between the first connector 310 and the main body is adjusted to achieve a rotatable connection between the first connector 310 and the main body.
[0054] In some embodiments, the elastic band sewing aid further includes a second connector 320, which is connected to the main body and is used to connect the elastic band sewing aid to the sewing equipment.
[0055] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of this patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
