Description

Technical Field

[0001] This utility model relates to the field of textile machinery and equipment manufacturing technology, and in particular to an anti-wrinkle hem sewing auxiliary tool. Background Technology

[0002] In the textile processing industry, hemming is a common technique widely used in garment manufacturing, home textile production, and other industries requiring fine sewing skills. The main purpose of hemming is to enhance the strength and aesthetics of the fabric edge by folding and sewing it inwards, while preventing fabric abrasion or tearing. Traditional hemming typically relies on the operator's manual skill and experience, involving manually folding the fabric edge and sewing with a standard presser foot. To improve efficiency and consistency, various hemming aids have emerged on the market, such as fixed hemming guides and dedicated hemming presser feet. However, most of these existing tools employ short guide designs, only guiding the fabric edge locally and lacking effective control over the overall direction of the fabric.

[0003] However, due to the short guide grooves, this design presents several problems in practical applications. The short guide grooves cannot provide sufficient continuous support, causing the fabric to easily shift and wrinkle during transport, especially when handling thin or elastic fabrics.

[0004] Therefore, it is necessary to provide an anti-wrinkle hem sewing auxiliary tool to solve the above problems. Summary of the Invention

[0005] To solve the above-mentioned technical problems, this utility model provides an auxiliary tool for anti-wrinkle hem sewing.

[0024] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0025] Please refer to the following: Figures 1 to 5 A wrinkle-resistant hem-rolling sewing aid tool, comprising:

[0026] Workbench 1;

[0027] Guide rail 2 is set on the surface of worktable 1;

[0028] The guide assembly has multiple sets, each set of which includes a locking block 301, a guide groove block 302, a connecting plate 303, and a first locking rod 304. The surface of the guide rail 2 is provided with a main limiting hole 305. The first locking rod 304 is slidably connected to the inner wall of the main limiting hole 305. The connecting plate 303 is fixedly connected to one end of the first locking rod 304. The locking block 301 is fixedly connected to the surface of the connecting plate 303, and the guide groove block 302 is fixedly connected to the surface of the locking block 301.

[0029] In the specific implementation process, the guide rail 2 is first installed on the workbench 1 by disassembling and assembling the components. Then, the guide component is lifted up, with the connecting plate 303 at the bottom and the locking block 301 at the top. At this angle, the first locking rod 304 is inserted into the main limiting hole 305. Then, the first locking rod 304 is rotated as the axis to make the locking block 301 lock on the guide rail 2, thus fixing the guide groove block 302. By rotating the locking block 301, the guide groove block 302 is made to fit tightly against the surface of the guide rail 2, thus achieving stable installation of multiple sets of guide groove blocks 302. The edge of the fabric can pass through multiple guide groove blocks 302. Through continuous guidance, fabric wrinkles are reduced, solving the problem of offset and wrinkling caused by the inability of traditional short guide grooves to provide continuous support, thus improving sewing efficiency and finished product quality.

[0030] refer to Figures 1 to 5As shown, the surface of the guide rail 2 is provided with multiple secondary limiting holes 4, and the multiple secondary limiting holes 4 and the multiple primary limiting holes 305 are arranged in a linear array.

[0031] In the above embodiment, the multiple secondary limiting holes 4 on the surface of the guide rail 2 are linearly arranged with the main limiting hole 305. When it is necessary to adjust the position of the guide block 302, the first locking rod 304 of the guide assembly is rotated out of the current main limiting hole 305 and inserted into the adjacent secondary limiting hole 4, so that the lateral spacing of the guide block 302 can be quickly changed to adapt to the hemming requirements of fabrics of different lengths without the need to change tools or reposition.

[0032] refer to Figures 1 to 5 As shown, it also includes a disassembly and assembly assembly, which includes a handle 501, a fixed cylinder 502, a limiting rod 503, a spring 504, a stop plate 505, a second connecting plate 507, and a insert plate 508. The surface of the worktable 1 has a connecting hole 506 and a slot 509. The fixed cylinder 502 is fixedly connected to the surface of the guide rail 2. The limiting rod 503 is slidably connected to the connecting hole 506 and the fixed cylinder 502. The stop plate 505 is fixedly connected to the circumferential surface of the limiting rod 503, and the stop plate 505 can slide. A spring 504 is sleeved on the circumferential surface of a limiting rod 503 and connected to the inner wall of a fixed cylinder 502. One end of the spring 504 is fixedly connected to the surface of abutment plate 505, and the other end of the spring 504 is fixedly connected to the inner wall of a fixed cylinder 502. A handle 501 is fixedly connected to one end of a limiting rod 503. A second connecting plate 507 is fixedly connected to one end of a guide rail 2. An insert plate 508 is fixedly connected to the surface of the second connecting plate 507 and is slidably connected to the inner wall of a slot 509.

[0033] In the above embodiment, when disassembling the guide rail 2, hold the handle 501 and pull the limiting rod 503 outward to disengage it from the connecting hole 506. At the same time, the insert plate 508 is pulled out of the slot 509 to remove the guide rail 2. When installing, the operation is reversed. After inserting the insert plate 508 into the slot 509, release the handle 501. The limiting rod 503 automatically resets and locks under the action of the spring 504. The whole process does not require tools, saves time, has high stability, and significantly improves the flexibility of the equipment.

[0034] refer to Figures 1 to 5 As shown, a storage slot 6 is provided on the surface of the guide rail 2.

[0035] In the above embodiment, the storage slot 6 provided on the surface of the guide rail 2 can be used to store small accessories such as scraper strips. During operation, there is no need to find additional tools; they can be taken directly from the storage slot 6 for use, reducing operation interruption time, improving work efficiency, and keeping the workbench 1 clean, avoiding the loss or messy accumulation of small accessories.

[0036] refer to Figures 1 to 5 As shown, the surface of the guide rail 2 is marked with scale marks 7.

[0037] In the above embodiment, the scale mark 7 on the surface of the guide rail 2 can accurately indicate the installation position of the guide block 302. During operation, the guide block 302 is aligned with the corresponding scale mark 7 according to the length of the fabric and then fixed to ensure that the installation position is consistent each time, reduce human error, and improve sewing accuracy.

[0038] refer to Figures 1 to 5 As shown, both ends of the guide block 302 are curved surfaces.

[0039] In the above embodiment, the guide block 302 is designed with curved surfaces at both ends, so that the fabric edge is subjected to more uniform force when passing through the guide groove, reducing wrinkles or damage caused by friction of right-angled edges. It is especially suitable for processing thin or elastic fabrics, making the rolled edge effect smoother and improving the appearance quality of the finished product. At the same time, it reduces the fabric wear rate and extends the service life of the tool.

[0040] The working principle of the anti-wrinkle hem-rolling sewing auxiliary tool provided by this utility model is as follows:

[0041] By setting a guide rail 2 with a main limiting hole 305 and a secondary limiting hole 4 on the workbench 1, and installing an adjustable guide component on the guide rail 2, the guide slot block 302 can be fixed in multiple desired positions. In use, the guide rail 2 is first installed on the workbench 1 through the insertion plate 508 and the slot 509, and then locked and fixed by the limiting rod 503 and the connecting hole 506. Then, the first locking rod 304 of the guide component is inserted into the main limiting hole 305, and the locking block 301 is rotated to make the guide slot block 302 stably fit against the guide rail 2. Multiple guide slot blocks 302 form a continuous guiding path, and the edge of the fabric passes through each guide slot block 302 in sequence. During the sewing process, it is continuously guided, reducing deviation and wrinkling. At the same time, the guide slot spacing can be precisely adjusted by the scale mark 7 to adapt to the needs of different lengths of fabric. The storage slot 6 can also be used to store small accessories, improving the convenience of operation. This structure effectively solves the problems of easy fabric deviation, wrinkling, and unstable sewing quality caused by the short and insufficient support of traditional guide slots in the background technology.

[0042] The above are merely embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
