A stepping motor 30 is installed on the side wall of the top plate of the mounting frame 21 through the machine base. The output shaft of the stepping motor 30 is fixedly connected to the screw rod 26. When working, the existing cloth cutting machine fixing device is in a loose state during the process of fixing the cloth, which makes cutting difficult and affects the cutting quality. The cloth is pressed and fixed by two sets of pressing plates 6. By turning the knob 31, the screw rod 17 is driven to rotate, and the first The moving block 16 moves horizontally, the first moving block 16 drives the support frame 3 to move horizontally, the support frame 3 drives the pressing plate 6 to move horizontally, and the positions of the two groups of pressing plates 6 are adjusted so that the pressing plates 6 move to both sides of the cloth when pressing the cloth, thereby achieving the straightening of the cloth.

The two sets of connecting rods 9 drive the two sets of pushing blocks 12 to move horizontally from the middle to both sides on the cloth, and the rollers 14 at the bottom of the pushing block 12 roll on the cloth, so that the pushing block 12 can move stably. In the process of moving to both sides, the pushing block 12 encounters the curled edge, and the pushing block 12 pushes the curled edge flat, thereby realizing rapid arrangement of the curled edge. After the arrangement is completed, the pressing plate 6 presses and fixes the cloth. This structure can The cloth is cut into two pieces by the threaded rod 16 and the threaded rod 17 is cut into two pieces by the threaded rod 16. The threaded rod 16 is pressed and fixed to the cloth by the two sets of pressing plates 6. By turning the knob 31, the screw 17 is driven to rotate, and the first movable block 16 on the screw 17 is moved horizontally. The first movable block 16 drives the support frame 3 to move horizontally, and the support frame 3 drives the pressing plate 6 to move horizontally, and the position of the two sets of pressing plates 6 is adjusted so that the pressing plate 6 moves to both sides of the cloth when pressing the cloth, thereby straightening the cloth. After the cloth is straightened, the stepping motor 30 is operated to drive the screw rod 26 to rotate, and the protrusion 27 on the screw rod 26 slides horizontally, and the protrusion 27 drives the fixing frame 28 to slide horizontally, and the fixing frame 28 drives the cutting knife 29 to slide horizontally, thereby cutting the cloth. This structure is beneficial to improving the cutting quality by straightening the cloth before cutting.
