[0022] See also Figure 1-3In this embodiment, the fixed structure includes a control frame 51 arranged on the top of the cutting machine 1. A lifting assembly 52 for driving the control frame 51 to move up and down is arranged on the top of the cutting machine 1. The lifting assembly 52 includes two electric push rods and two connecting plates. The two connecting plates are fixedly installed on the left and right sides of the control frame 51 respectively. The telescopic ends of the two electric push rods are fixedly connected to the bottoms of the two connecting plates respectively. The bottoms of the two electric push rods are fixedly installed on the top of the cutting machine 1, which is convenient for driving the control frame 51 and the PET fabric to move up and down. A connecting block 53 is slidably installed inside the control frame 51. A guide assembly 54 for limiting the sliding trajectory of the connecting block 53 is arranged inside the control frame 51. The guide assembly 54 includes a guide rod and a connecting hole. The guide rod is fixedly installed on the left and right side walls of the inner cavity of the control frame 51. The connecting hole is opened inside the connecting block 53. One end of the guide rod passes through the connecting hole. The outer surface of the guide rod is slidably connected to the inner wall of the connecting hole to limit the connecting block 53 to move left and right only on the outer surface of the guide rod. A traction frame 55 is fixedly connected to the front of the connecting block 53. A positioning assembly 56 for fixing the PET fabric is arranged on the traction frame 55 to facilitate clamping of the PET fabric.

[0023] It should be noted that the positioning assembly 56 includes a cylinder and a pressure plate. The cylinder is fixedly mounted on the traction frame 55, and the pressure plate is fixedly mounted on the telescopic end of the cylinder, so that the cylinder can be used to control the pressure plate to move downward, thereby clamping the PET fabric on the traction frame 55.

[0024] By adopting the above technical scheme, it is possible to start the cylinder in the positioning component 56 and control the pressure plate to move downward, so as to fix one end of the PET fabric inside the traction frame 55, and use the position adjustment structure to control the connecting block 53 to move to the right on the outer surface of the guide rod, so that the moving connecting block 53 drives the traction frame 55 and the fixed PET fabric to move to the right synchronously, thereby achieving automatic traction of the PET fabric, and controlling the traction frame 55 and the fixed PET fabric to move downward to the cutting table 2 and flatten them through the lifting component 52, thereby achieving equal-length traction of PET fabrics, which is convenient for cutting out equal-length PET fabric blocks.

[0025] See also Figure 1-3 In this embodiment, the position adjustment structure includes a screw rod 57 rotatably installed between the left and right side walls of the inner cavity of the control frame 51, and the connecting block 53 is threadedly installed on the outer surface of the screw rod 57, so that the rotating screw rod 57 can control the left and right movement of the connecting block 53.

[0027] By adopting the above technical solution, the asynchronous motor 58 is started and the output shaft is driven to rotate, and the belt in the transmission assembly 59 is used to drive the screw rod 57 to rotate, thereby causing the connecting block 53 threadedly connected to the outer surface of the screw rod 57 to move to the right on the outer surface of the guide rod.

[0028] The working principle of the above embodiment is:

[0029] The PET fabric cutting machine starts the cylinder in the positioning component 56 and controls the pressure plate to move downward, thereby fixing one end of the PET fabric inside the traction frame 55, starts the asynchronous motor 58 and drives the output shaft to rotate, and uses the belt in the transmission component 59 to drive the screw rod 57 to rotate, so that the connecting block 53 threadedly connected to the outer surface of the screw rod 57 moves to the right on the outer surface of the guide rod, and then the moving connecting block 53 drives the traction frame 55 and the fixed PET fabric to move synchronously to the right until the connecting block 53 squeezes the pressure sensor, thereby controlling the asynchronous motor 58 to stop, and automatically traction of the PET fabric is achieved, and the traction frame 55 and the fixed PET fabric are controlled by the lifting component 52 to move downward to the cutting table 2 to be flattened, thereby achieving equal-length traction of the PET fabric, and conveniently cutting out equal-length PET fabric blocks.
