Description

Technical Field

[0001] This utility model relates to a fabric fixing device for a denim cutting machine, belonging to the technical field of cutting machines. Background Technology

[0002] Cutting machines are automated devices widely used in industries such as textiles, leather, and paper to precisely cut materials into predetermined shapes and sizes. With increasing demands for production efficiency and precision, traditional manual cutting has become increasingly inadequate for large-scale production. Modern cutting machines employ advanced control systems and drive technologies to achieve automated operation, effectively improving cutting speed and accuracy. Especially in the textile industry, cutting machines must adapt to fabrics of different materials and thicknesses, and handle complex cutting patterns and precise fabric layouts. Therefore, the design of cutting machines must consider not only cutting accuracy and speed but also fabric characteristics, fixing methods, and blade life, among other factors, to ensure an efficient and stable production process.

[0003] Authorization announcement number (CN217869654U) discloses a fabric cutting fixing device. This device includes a worktable, a mounting frame fixedly connected to the top of the worktable, two electric push rods fixedly mounted on the inner top wall of the mounting frame, a support plate slidably connected to the inner wall of the mounting frame, the bottom end of each electric push rod fixedly connected to the top of the support plate, a servo motor fixedly mounted on the bottom of the support plate, and a cutting blade threaded onto the output shaft of the servo motor. This invention uses an air pump to generate suction through suction holes to adsorb and pull the fabric, thereby reducing manual labor and eliminating the need for repeated fabric pulling before cutting, which affects cutting efficiency. The spring and pressure plate configuration allows for pressure on both sides of the cutting area during cutting, preventing the fabric from shifting due to elasticity and resulting in poor cutting quality.

[0004] The aforementioned fabric cutting machine uses an air pump to generate suction, employing suction holes to adsorb and pull the fabric, thereby reducing manual operation and improving cutting efficiency. However, fabrics typically have a certain degree of breathability, which may lead to less than ideal air pump traction, especially with thinner or more breathable fabrics. In such cases, the suction force may be insufficient to effectively hold the fabric, thus affecting the accuracy and stability of the cutting process. Although the design using springs and pressure plates can alleviate the fabric slippage problem to some extent, it is still necessary to consider how to enhance the air pump traction force in the design to ensure a stable traction effect under different fabric types.

[0005] Therefore, a fabric fixing device for a denim cutting machine is proposed. Utility Model Content

[0006] In view of this, the present invention provides a fabric fixing device for a denim cutting machine to solve or alleviate the technical problems existing in the prior art, and at least provides a beneficial option.

[0031] By using the clamping and stretching assembly 9, the output of the second motor 907 drives the second threaded rod 902 to rotate. Simultaneously, the rotation of the second threaded rod 902 drives the first gear 904 to rotate and the two second threaded sleeves 903 to move inward. The first gear 904, through its meshing with the second gear 906, drives the two second threaded sleeves 903 on the surface of the second threaded rod 902 on the other side to move inward. By activating the cylinder 911, the cylinder 911 drives the clamping plate 912 to press down and clamp both ends of the fabric. By reversing the activation of the second motor 907, the fabric is stretched and pulled, effectively improving the stability and cutting accuracy of the fabric. Simultaneously, the fabric is moderately stretched, keeping it flat during the cutting process and avoiding cutting errors caused by fabric looseness or deformation.
