Description

Technical Field

[0001] The utility model relates to the technical field of fabric shearing, in particular to a device for shearing elastic fabrics. Background Art

[0002] With the continuous development of the textile industry, elastic fabrics are increasingly used in clothing, home textiles, and industrial products. However, traditional elastic fabric processing methods suffer from low efficiency and poor precision. This is particularly true for shearing, where traditional mechanical shearing methods struggle to meet the demands for high precision and complex patterns. Consequently, the application of laser cutting technology in elastic fabric processing has gradually gained attention. However, existing shearing devices still suffer from issues such as inaccurate fabric positioning and inability to quickly remove pre-cut threads.

[0003] Therefore, it is very necessary to invent a kind of elastic fabric cutting device. Utility Model Content

[0004] In order to solve the above technical problems, the present invention provides an elastic fabric cutting device to solve the problem that the existing fabric cutting device still has the problem of being unable to accurately position the fabric and unable to quickly remove the thread ends before cutting. An elastic fabric cutting device includes a support base, a support plate, a fabric positioning roller group, a silk thread discharge box, a silk thread discharge trough, a laser cutting structure and fabric, wherein: the support base adopts two groups and is fixedly installed on the ground, and the support plates are respectively fixedly installed on the top of the two groups of support bases, the fabric positioning roller group is respectively fixedly installed on the two groups of support plates; the silk thread discharge box is fixedly installed between the two groups of fabric positioning roller groups, and the silk thread discharge trough is fixedly installed between the two groups of support bases, and the laser cutting structure is fixedly installed inside the silk thread discharge trough; the fabric is located inside the two groups of fabric positioning roller groups and below the silk thread discharge box.

[0005] The cloth positioning roller group includes a support frame, a sliding seat, a downward pressing push rod, a movable roller and a support roller, and the support frame is fixedly installed at both ends of the support plate, and the sliding seat is slidably installed inside the support frame; the downward pressing push rod is fixedly installed between the support frame and the sliding seat, and the movable roller is rotatably installed inside the sliding seat, and the support roller is rotatably installed on the inner side of the bottom of the support frame.

[0006] The wire stripping box includes a support beam, a support arm, a high-pressure box, a protective layer and a pressurized tube, and two groups of support beams are used, which are fixedly installed inside two groups of cloth positioning roller groups respectively; the high-pressure box is installed on the inner side of the support beam through the support arm, and the protective layer is bonded to the surface of the high-pressure box, and the pressurized tube is fixedly installed on the top of the high-pressure box.

[0007] The moving roller inside the fabric positioning roller group can move back and forth in the vertical direction, and neither the moving roller nor the support roller can rotate actively. The moving roller and the support roller can rotate passively through the friction of the fabric, and have the following functions: ① Fabric positioning: The fabric positioning roller group is used to accurately position the fabric to ensure that the fabric remains stable and flat during the cutting process, avoiding the impact of fabric shifting on cutting accuracy; ② Fabric fixing: The downward push rod fixes the fabric between the support frame and the sliding seat to prevent the fabric from sliding or shifting during transportation, thereby ensuring the accuracy of the cutting lines; ③ Support provision: The support frame and the sliding seat provide a stable support structure for the fabric, ensuring that the fabric will not be deformed or shifted due to its own weight or external force during the cutting process.

[0008] The high-pressure box inside the thread removal box is a stainless steel metal box with a rounded top and bottom, and a protective layer made of a smooth, hard rubber. Several air outlets are located within the box and the protective layer. These outlets eject high-speed air, discharging the threads from the fabric downward, facilitating subsequent cutting. A pressurized tube connected to an air pump supplies air to the high-pressure box, which performs the following functions: 1. Thread separation and removal: The high-speed airflow generated by the high-pressure box separates the threads from the fabric and ejects them downward. This helps clean loose threads from the fabric surface, ensuring a smooth cutting process. 2. Protection: The thread removal box is equipped with a protective layer to prevent damage to the equipment or operators caused by the high-speed airflow. The protective layer is made of a smooth, hard rubber layer, enhancing safety and durability. 3. Assisted cutting: By ejecting the threads downward, the thread removal box provides a cleaner, tidier surface for the subsequent laser cutting process, improving cutting accuracy and quality.

[0009] Compared with the prior art, the present invention has the following beneficial effects:

[0010] 1. The setting of the cloth positioning roller group of the utility model has the following functions: ① Cloth positioning: The cloth positioning roller group is used to accurately position the cloth, ensuring that the cloth remains stable and flat during the cutting process, and avoiding the impact of cloth shifting on cutting accuracy; ② Cloth fixing: The downward push rod fixes the cloth between the support frame and the sliding seat to prevent the cloth from sliding or shifting during the transmission process, thereby ensuring the accuracy of the cutting line; ③ Support provision: The support frame and the sliding seat provide a stable support structure for the cloth, ensuring that the cloth will not be deformed or shifted due to its own weight or external force during the cutting process.

[0011] 2. The setting of the wire removal box of the utility model has the following functions: ① separation and removal of wires:

[0012] The thread release box uses high-speed airflow generated by a high-pressure box to separate the threads from the fabric and eject them downward. This helps clean any loose threads from the fabric surface, ensuring a smooth cutting process. ② Protection: The thread release box is equipped with a protective layer to prevent damage to the equipment or operators caused by the high-speed airflow. This protective layer is made of a smooth hard rubber layer, which not only increases safety but also improves the durability of the equipment. ③ Assisted Cutting: By ejecting the loose threads downward, the thread release box provides a cleaner and tidier fabric surface for the subsequent laser cutting process, thereby improving cutting precision and quality.
