[0002] Cutting is a crucial step in the manufacturing process of down jackets. The main purpose of cutting is to cut the fabric into the necessary components, such as the front panel, back panel, sleeves, hood, and pockets, according to the design drawings. Cutting not only affects the final product's appearance and dimensions but also directly impacts fabric utilization and production costs. Proper fabric layout can minimize waste and maximize fabric utilization.
[0003] In existing technologies, down jacket fabrics are usually lightweight and have a smooth surface (such as high-density nylon, polyester, etc.), which are prone to displacement or wrinkling during the conveying and cutting process, resulting in deviations in the size of the cut pieces, which in turn affects the uniformity of subsequent sewing and down filling. Therefore, we propose a fabric rotation cutting device to solve the above problems. Utility Model Content

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.
[0020] Depend on Figures 1-3 As shown, a fabric rotary cutting device is disclosed, including a cutting machine body 1 (ZCS-1625). Two rollers 2 are rotatably connected inside the cutting machine body 1 (ZCS-1625). The outer walls of the two rollers 2 are fitted with the same conveyor belt 3. There is tension between the conveyor belt 3 and the two rollers 2. A first linear motor 4 is fixedly installed on the outer wall of the cutting machine body 1. A frame 5 is fixedly connected to the outer wall of the moving end of the first linear motor 4. A second linear motor 6 is fixedly connected to the top of the frame 5. A guide rail is provided on the outer wall of the frame 5. The first linear motor 4 and the second linear motor 6 are used to control the forward and backward and left and right movements of the cutting blade 9, respectively.
[0021] The outer wall of the moving end of the second linear motor 6 is fixedly connected to the frame 7. The inside of the frame 7 is fixedly connected to the electric push rod 8. The outer wall of the frame 7 is provided with a sliding hole. The inner wall of the sliding hole is slidably connected to the outer wall of the output end of the electric push rod 8. The electric push rod 8 can automatically adjust the downward pressure of the cutting blade 9 according to different fabric thicknesses to avoid overcutting or incomplete cutting. It is especially suitable for multi-layer composite down jacket fabrics.
[0022] A cutting blade 9 is fixedly connected to the bottom of the output end of the electric push rod 8, and an ear plate 10 is fixedly connected to the outer wall of the moving end of the second linear motor 6. An L-shaped tube 11 is fixedly connected inside both ear plates 10.
[0023] The outer wall of the I-beam frame 5 is provided with a cutting auxiliary component, which includes two vertical tubes 12. The inner walls of the two L-shaped tubes 11 are slidably connected to the outer walls of the two vertical tubes 12 respectively. A gasket 13 is fixedly sleeved on the outer wall of the vertical tube 12. A spring 14 is sleeved on the outer wall of the vertical tube 12. The bottom of the spring 14 is fixedly connected to the top of the gasket 13. The top of the spring 14 is fixedly connected to the bottom of the L-shaped tube 11. A ball sleeve 15 is fixedly connected to the bottom of the vertical tube 12. A ball 16 is rotatably connected inside the ball sleeve 15.
[0024] During the cutting process, the two spheres 16 are always in close contact with the fabric under the elastic force of the spring 14 and move synchronously with the cutting blade 9 to prevent the fabric from shifting or warping during cutting. The bottom of the spheres 16 is in contact with the outer wall of the conveyor belt 3. The spheres 16 can rotate flexibly inside the ball sleeve 15 to reduce friction with the fabric and avoid scratching the high-density coated fabric.
[0025] Working principle: During use, the fabric is placed on the conveyor belt 3, and the fabric is loaded and unloaded by the rotation of two rollers 2. The rotation of the rollers 2 is driven by the existing drive equipment. During cutting, the first linear motor 4 drives the I-frame 5 and the cutting blade 9 to move back and forth, while the second linear motor 6 drives the frame 7 and the cutting blade 9 to move left and right to adjust the position of the cutting blade 9. During cutting, the electric push rod 8 drives the cutting blade 9 to move downward to contact the fabric. The cutting blade 9 is driven by the existing electric motor to cut the fabric. During the cutting process, the two balls 16 move synchronously with the position of the cutting blade 9. The two balls 16 rotate through the ball sleeve 15, and the two balls 16 are kept in contact with the fabric by the elastic force of the two springs 14. During the contact process, the cutting part is limited to prevent the fabric from deviating.
[0026] It should be noted that, in actual use, an existing PLC controller can be added. The PLC controller is electrically connected to the first linear motor 4, the second linear motor 6, and the electric push rod 8 to facilitate the control of the overall operation.
