Detailed Implementation
[0021] To further explain the technical solution of this utility model, a detailed description is provided below through specific embodiments.
[0022] Please see Figure 1 and Figure 2 This utility model provides an automatic fabric edge cutting device, including a fixed platform 1, a mounting frame 2 fixed to the top of the fixed platform 1 by bolts, a pressure roller 3 in the mounting frame 2, a fabric roller 4 in the middle of the mounting frame 2, and an adjustable cutter structure 5 in the mounting frame 2.
[0023] Connect the external drive device to the pressure roller 3 and the fabric roller 4. Insert the fabric to be trimmed into the mounting frame 2 and place it on the pressure roller 3 and the fabric roller 4. Turn on the external drive device to make the pressure roller 3 and the fabric roller 4 rotate. The rotation of the pressure roller 3 and the fabric roller 4 will drive the fabric. Then the edge trimming knife 512 on the adjustable cutting structure 5 will automatically trim the edge of the fabric.
[0024] Please see Figure 2 and Figure 3 This utility model provides an automatic fabric edge trimming device. The adjustable cutter structure 5 includes a positioning frame 51. The positioning frame 51 is fixed to the middle of the inner side of the mounting frame 2 by bolts. A guide rail 52 is installed inside the positioning frame 51. An adjusting rod 53 is provided in the positioning frame 51 and is fixed to the inner side of the mounting frame 2 by bolts. An adjusting block 54 is installed in the positioning frame 51. The adjusting block 54 is slidably connected to the guide rail 52. A sliding sleeve 55 is installed in the adjusting block 54 and is slidably connected to the adjusting rod 53 so that the adjusting block 54 can slide on the surface of the adjusting rod 53 to adjust its position. An mounting plate 510 is integrally formed at the bottom end of the adjusting block 54. Screw holes 511 are opened at both the left and right ends of the mounting plate 510. An edge trimming knife 512 is installed on the mounting plate 510. Then, a screw passes through the edge trimming knife 512 and the mounting plate 510 and is locked into the screw hole 511 to realize the installation of the edge trimming knife 512.
[0025] A threaded sleeve 56 is welded to the top of the positioning frame 51. A screw 57 is threadedly connected to the threaded sleeve 56. A knob 58 is fixed to one end of the screw 57, and a limit block 59 is provided at the other end. A limit groove 531 is opened at the bottom of the adjusting rod 53. The limit block 59 can be moved into the limit groove 531 and pressed on the adjusting rod 53. When the limit block 59 can be moved into the limit groove 531, the surface of the limit block 59 is in contact with the inner surface of the limit groove 531, which improves the stability of the adjusting block 54 fixed on the adjusting rod 53 and prevents unstable shaking after the adjusting block 54 is fixed.
[0026] The trimming blade 512 has a mounting port 5121 in the middle, which can be inserted into the mounting plate 510. The insertion installation makes the trimming blade 512 more stable. The bottom of the adjusting block 54 is equipped with a pressure pad 5122. The pressure pad 5122 is elastic. After the mounting port 5121 is inserted into the mounting plate 510, it will press on the surface of the pressure pad 5122 and press the pressure pad 5122, which improves the stability of the trimming blade 512 installation.
[0027] Rotating knob 58 causes screw 57 to rotate. Since screw 57 is threadedly connected to threaded sleeve 56, when screw 57 rotates, it will move upward and slide out of limit groove 531, thereby releasing the limit on adjusting block 54. Then, adjusting block 54 can be moved along the surface of adjusting rod 53 and guide rail 52, and moves within positioning frame 51. When adjusting block 54 moves, it will drive edge trimmer 512, thereby adjusting the position of edge trimmer 512. This allows the position of edge trimmer 512 to be adjusted according to the specifications of the fabric, achieving the beneficial effect of adapting to different sizes of fabric.
