Description

Technical Field

[0001] This utility model relates to the field of clothing fabric cutting technology, specifically a quick clamping assembly for a positioning ruler used in clothing fabric cutting. Background Technology

[0002] In the field of custom clothing and sample garment production, the accuracy of fabric cutting directly affects the pattern and production efficiency of the finished garment. Therefore, the positioning process has always been a core focus of the industry. Currently, when manually cutting clothing fabric, the positioning operation mostly relies on traditional methods: operators usually use a ruler for basic positioning. After determining the cutting boundary, they either mark the cutting path with lines or use pre-made paper or plastic templates to cover the fabric surface as a reference. Then, they use a straight cutter or a roller cutter to complete the cutting operation along the marked lines or the edge of the template.

[0003] However, this traditional operating mode has many limitations in practical applications and cannot meet the demands of modern garment manufacturing for efficiency, environmental protection, and convenience. First, some special fabrics (such as high-grade silk, tulle, flocked fabrics, etc.) have sensitive surfaces, and the markings will leave marks that are difficult to remove, damaging the appearance of the fabric and even affecting the quality of the finished garment. If a marking-free operation is used, the operator must press the positioning ruler by hand throughout the process to prevent it from shifting. This not only increases hand fatigue but may also cause the ruler to tilt due to uneven pressure, resulting in cutting errors.

[0004] Secondly, while the use of paper molds and plastic molds solves the problem of positioning stability, it consumes a large amount of paper or plastic materials, increases production costs, and generates a large amount of waste, which contradicts the green and environmentally friendly concept advocated by the current apparel industry.

[0027] Furthermore, a second flexible pad 17 is provided in the second groove 15. The first flexible pad 13 and the second flexible pad 17 are used to avoid rigid contact. If the positioning ruler used is made of steel, the first flexible pad 13 and the second flexible pad 17 are required to prevent damage to the steel ruler or the device. If the positioning ruler used is made of plastic, the first flexible pad 13 and the second flexible pad 17 are not required.

[0028] Furthermore, a functional notch 18 is provided on the side of the pressure block 2 near the positioning scale. The functional notch 18 can be used as needed, and the user can place the edge of the fabric at the functional notch 18.

[0029] Furthermore, the ruler fixing assembly 14 includes multiple sets of press-fit buckles 20 and a plastic sheet 21. The upper pressure block 1 has a square structural groove 19 that intersects with the first ruler groove 11. The press-fit buckles 20 are fixedly disposed on both sides of the structural groove 19.

[0031] Working Principle: The working principle of this quick-clamping assembly for positioning rulers in garment fabric cutting is to achieve quick clamping, stable fixation, and flexible sliding adjustment of the positioning ruler through the coordinated cooperation of various structures, thereby efficiently assisting garment fabric cutting operations. The assembly uses an upper pressure block 1 and a lower pressure block 2 as the core clamping structure, both of which adopt an aluminum square block design. The upper pressure block 1 is located directly above the lower pressure block 2, and the two are hinged together by a hinge assembly 4 on one side. The hinge assembly 4 specifically consists of two sets of hinge ears 5 fixed to the upper pressure block 1, a central protrusion 6 fixed to the lower pressure block 2 and located between the two sets of hinge ears 5, and a rotating shaft 7 passing through the hinge ears 5 and the central protrusion 6. The rotating shaft 7 is rotatably connected to the hinge ears 5 and the central protrusion 6. During use, the upper pressure block 1 can be rotated to open and close, making it easy to insert or remove the positioning ruler. After clamping, the positioning ruler can be placed against the fabric to be cut. During adjustment, the upper pressure block 1 and the positioning ruler can be easily slid by slightly raising them. The horizontal sliding rail 3 is fixed to the horizontal side of the workbench. Its fixing method is flexible; it can be fixed together with the workbench or moved using a simple bracket. The horizontal sliding groove 8 on the lower pressure block 2 slides and engages with the horizontal sliding rail 3. The groove 9 on the side of the rail near the positioning scale cooperates with the corresponding protrusion 10 in the sliding groove 8, ensuring stable sliding without derailment. The upper pressure block 1 and lower pressure block 2 achieve sliding adjustment along a single axis through this rail structure, facilitating the movement of the clamped positioning scale to the desired position. The upper pressure block 1 has a first ruler groove 11 on the side near the lower pressure block 2. A magnet 12 and a first flexible pad 13 are located at the bottom. A ruler fixing assembly 14 is also provided at the corresponding position. This assembly includes multiple sets of press-fit buckles 20, plastic sheets 21, and a square structural groove 19 on the upper pressure block 1 that intersects with the first ruler groove 11. The press-fit buckles 20 are fixed to both sides of the structural groove 19. The plastic sheets 21 are connected to the press-fit buckles 20 through their snap-fit ​​openings and are detachably fixed within the structural groove 19. The lower pressure block 2 is used to further clamp the positioning scale. It can be released by pressing or applying force during loading and unloading. The lower pressure block 2 has a second scale groove 15 corresponding to the first scale groove 11. The bottom is provided with a ferromagnetic metal block 16 and a second flexible pad 17. Since the lower pressure block 2 is made of aluminum, the ferromagnetic metal block 16 can cooperate with the magnetic block 12 of the upper pressure block 1 to form a fixing force and prevent the scale from loosening. The first flexible pads 13 and 17 can prevent the steel scale from being damaged by rigid contact with the device. If a plastic scale is used, these pads can be omitted. In addition, the lower pressure block 2 has a functional notch 18 on the side near the positioning scale. The user can place the edge of the fabric here to assist in positioning.During overall operation, the upper pressure block 1 is first opened through the hinge assembly, and the positioning ruler is placed between the first ruler groove 11 and the second ruler groove 15. It is initially clamped by the plastic sheet 21 of the ruler fixing assembly 14, and then further fixed by the attraction of the magnetic block 12 and the ferromagnetic metal block 16. Subsequently, the assembly is slid to the required position by the horizontal sliding rail 3. It is stable by the weight of the upper pressure block 1 and the lower pressure block 2, without the need for manual pressing. When cutting, it is operated directly along the edge of the positioning ruler. There is no need to draw lines on the fabric or use paper molds or plastic molds. It is both environmentally friendly and convenient. Moreover, through the selective use of flexible pads and flexible rail fixing methods, it can adapt to the needs of different materials of rulers and workbenches, making it highly practical.

[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
