The bottom of the second moving block 14 is connected to the cutting component.
[0023] The clamping mechanism 5 includes an upper connecting frame 51, a lower connecting frame 52, an upper clamping roller 53, and a lower clamping roller 54.

[0024] The pressing mechanism 6 includes a top plate 61, connecting blocks 62, a first screw 63, a drive mechanism 64, pressing components 65, and a first moving block 66. Two connecting blocks 62 are fixed on the bottom surface of the top plate 61, and the first screw 63 is rotatably mounted between the two connecting blocks 62. The first screw 63 is driven by the drive mechanism 64.

It is highly practical.
[0025] The drive mechanism 64 includes a first gear 641, a second gear 642, and a drive motor 643.

The output shaft of the cutting motor 17 is connected to the cutting blade 18.
[0028] In actual operation, the mesh fabric to be cut enters the clamping mechanism 5 between the upper clamping roller 53 and the lower clamping roller 54. The motor driving the upper clamping roller 53 and the lower clamping roller 54 is activated, causing the upper clamping roller 23 and the lower clamping roller 24 to rotate, clamping and conveying the mesh fabric to the cutting table 2. Then, the first cylinder 652 is activated, driving the first piston rod 653 to move, which in turn causes the pressure plate 654 to descend, thus pressing the mesh fabric and preventing it from shifting during cutting, improving the pass rate of mesh fabric cutting. Next, the positioning bracket 10 is moved according to the required cutting length of the mesh fabric. The position of the positioning bracket 10 is determined by the position of the scale line 4 pointed to by the tip 101. After determination, the position of the positioning bracket 10 is fixed by the fixing bolt 9. Then, the cutting motor 17 is activated, driving the cutting blade 18 to rotate. Simultaneously, the motor 13 is activated, driving the second screw 12 to rotate, which in turn drives the second moving block 14 to move, thereby moving the entire cutting bracket 15 to achieve the moving cutting of the mesh fabric (during cutting, the blade and the tip are on the same horizontal line).
