Technical Field

[0001] This invention relates to the field of clothing technology, specifically to a strip limiting structure and a sewing device. Background Technology

[0002] Sewing, in olden times, referred to the textile, sewing, and embroidery work done by women.

[0003] A sewing machine is a machine that uses one or more sewing threads to create one or more stitches on fabric, allowing one or more layers of fabric to interweave or sew together. This has led to the development of art forms such as hand embroidery and computer embroidery.

[0004] Sewing machines can sew fabrics such as cotton, linen, silk, wool, and synthetic fibers, as well as products made of leather, plastic, and paper. The stitches produced are neat, beautiful, flat, and strong. The sewing speed is fast and the machine is easy to use.

[0005] Most ordinary double-needle sewing machines include a base plate, on which a sewing head is fixed. Various mechanical mechanisms are installed on the sewing head and the base plate, and these mechanisms work together to complete ordinary sewing.

[0006] Currently, when sewing a strip onto fabric, workers need to manually place and control the strip's orientation, which can easily lead to distortion and affect the yield rate. This is especially true when sewing multiple strips at the same time, which requires multiple sewing operations and greatly reduces the yield rate. Summary of the Invention

[0007] In view of this, the purpose of the present invention is to provide a strip limiting structure and a sewing device to solve the technical problem in the prior art that when sewing strips on fabric, workers need to manually place and control the position of the strips, which is troublesome and prone to distortion.

[0024] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be described in detail below. Obviously, the described embodiments are merely some embodiments of this invention, and not all embodiments. Based on the embodiments of this invention, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0025] See Figs. 1-2The present invention provides a strip limiting structure, including an mounting part 1 and a limiting part 2. The limiting part 2 is provided with mounting parts 1 at both ends. The limiting part 2 is mounted on the pressure plate 3 of the sewing machine through the mounting parts 1, and the strip limiting structure can slide relative to the pressure plate 3 through the mounting parts 1 to adjust the position of the strip limiting structure. A strip channel 5 is formed on the limiting part 2 to allow the strip to pass through. The rough edges on both sides of the strip along its length direction are bent and can pass through the strip channel 5 and be placed between the pressure plate 3 and the base plate of the sewing machine.

[0026] In this embodiment, the mounting part 1 is generally U-shaped, including a first vertical plate 11, a second vertical plate 12, and a horizontal connecting plate 13. The first vertical plate 11 and the second vertical plate 12 are arranged opposite to each other. The horizontal connecting plate 13 is used to connect the first vertical plate 11 and the second vertical plate 12. The first vertical plate 11, the second vertical plate 12, and the horizontal connecting plate 13 form a clamping cavity, which is used to clamp the pressure plate 3. The first vertical plate 11 can be connected to the limiting part 2, or the second vertical plate 12 can be connected to the limiting part 2, and the limiting part 2 is located on the outside of the pressure plate 3.

[0027] In this embodiment, the limiting part 2 includes a first blocking plate 21, a second blocking plate 22, and an intermediate connecting plate 23. The intermediate connecting plate 23 is used to connect the first blocking plate 21 and the second blocking plate 22. The first blocking plate 21 and the second blocking plate 22 are respectively fixedly connected to the corresponding mounting part 1, and the structure is stable. When the strip passes through the strip channel 5, the first blocking plate 21 and the second blocking plate 22 can respectively prevent the rough edges on both sides of the strip from unfolding.

[0028] Typically, the distance between the first baffle plate 21 and the second baffle plate 22 is the same as the width of the strip after the rough edge is bent.

[0029] For example, the width of the raw edges on both sides of the strip before bending is 1.5 to 2 cm. When sewing, the raw edges on both sides need to be bent. After bending, the strip is placed under the pressure plate 3 through the strip channel 5, which is above the base plate of the sewing machine. The width of the strip after the raw edges are bent is usually 1 cm. In other words, the distance between the first blocking plate 21 and the second blocking plate 22 in this embodiment is usually set to 1 cm.

[0030] As an optional embodiment of the present invention, the connection between the first blocking plate 21 and the intermediate connecting plate 23 and the connection between the second blocking plate 22 and the intermediate connecting plate 23 are both smoothly transitioned connections, which can reduce friction with the strip and effectively prevent wear on the strip.

[0031] The first blocking plate 21 and the second blocking plate 22 are detachably fixedly connected to the corresponding mounting part 1 by bolts. The connection method is simple and facilitates the installation and disassembly of the limiting part 2 and the mounting part 1.

[0032] Furthermore, the present invention provides a sewing device, including a sewing machine and the aforementioned strip limiting structure, wherein the strip limiting structure and the pressure plate 3 of the sewing machine are slidably connected, which facilitates the adjustment of the position of the strip limiting structure.

[0033] The sewing machine includes a pressure plate 3 and a base plate. The pressure plate 3 includes a flat plate 31 and a vertical plate 32 connected to the flat plate 31. The flat plate 31 is used to place fabric and strips between the base plate and the flat plate. The strips are located above the fabric, and a strip limiting structure is installed on the vertical plate 32.

[0034] The number of strip limiting structures provided on the pressure plate 3 is at least two, and the strip limiting structures are spaced apart on the pressure plate 3 according to actual use needs.

[0035] like Fig. 2 The sewing device shown has three strip limiting structures, and the corresponding sewing machine has three sets of needles 4. In addition, a long strip groove 6 is provided on the flat plate 31 to allow the sewing machine needles 4 to pass through. This sewing device can sew three strips simultaneously, improving work efficiency.

[0036] When using it, first install the strip limiting structure on the pressure plate in advance, and you can easily pass the strip through the strip channel and place it between the fabric on the base plate and the pressure plate 3. This improves the yield rate when sewing and reduces the occurrence of distortion and unevenness when sewing multiple strips.

[0037] The above are merely specific embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
