[0023] In use: Place the wire mesh on the cutting table 1, adjust the position of the wire mesh, and position the cutting part of the wire mesh below the cutting blade 7. Drive the hydraulic cylinder 8 to drive the mounting plate 6 to descend. The descending mounting plate 6 drives the cutting blade 7 to descend. The descending cutting blade 7 contacts the wire mesh and applies pressure. Under the action of pressure, the wire mesh is cut. Before the cutting blade 7 contacts the wire mesh, the elastic pressure plate 9 first contacts both sides of the cutting part of the wire mesh. As the cutting blade 7 descends, it squeezes and compresses the spring 16. The squeezed spring 16 applies a pushing force to the elastic pressure plate 9. The elastic pressure plate 9 pre-clamps and fixes the cut wire mesh.

[0024] Please see Figure 1 and Figure 2 Infrared positioners 11 are provided at the bottom of both ends of the mounting plate 6. There are two infrared positioners 11, and the infrared positioners 11 are connected to the mounting plate 6 by screws. The two infrared positioners 11 are located on both sides of the cutting blade 7. The infrared positioners 11 emit infrared rays to shine on the mesh to be cut. The infrared rays coincide with the cutting part of the mesh, thereby positioning the mesh and improving the cutting accuracy.

[0025] Please see Figure 1 and Figure 3 The inner wall of the cutting frame 4 is provided with a first guide groove 17. There are two first guide grooves 17. Both ends of the mounting plate 6 extend into the interior of the first guide groove 17, and the mounting plate 6 is slidably connected to the cutting frame 4. Both ends of the mounting plate 6 are provided with ball bearings 12, and the ball bearings 12 are in contact with the inner wall of the first guide groove 17. The ball bearings 12 are rollingly connected to the cutting frame 4 and the mounting plate 6. The first guide groove 17 guides the lifting and lowering of the mounting plate 6. The ball bearings 12 reduce the lifting and lowering resistance of the mounting plate 6, so that the lower end of the cutting blade 7 is horizontal when it is lifted and lowered, ensuring the cutting effect of the mesh.

[0026] Please see Figure 1 and Figure 4 The upper end of the cutting table 1 is provided with an installation cavity 10. There are two installation cavities 10.

The two second guide grooves 21 are provided with sliders 20 inside, and the sliders 20 are slidably connected to the cutting table 1. The sliders 20 are fixedly connected to the U-shaped frame 19. The electric push rod 18 drives the U-shaped frame 19 to rise and fall. The rise of the U-shaped frame 19 lifts the feeding roller 3. The feeding roller 3 contacts the mesh, which can reduce the friction of the mesh and make it easier to adjust the mesh. After the mesh is adjusted, the feeding roller 3 is put back into the mounting cavity 10.

[0027] Working principle: The wire mesh is placed on the cutting table 1 and its position is adjusted so that the cutting part is positioned below the cutting blade 7. The infrared positioner 11 is activated to emit infrared light onto the wire mesh to be cut. When the infrared light coincides with the cutting part of the wire mesh, the hydraulic cylinder 8 is driven to lower the mounting plate 6. The lowering mounting plate 6 drives the cutting blade 7 to lower as well. The elastic pressure plate 9 first contacts both sides of the cutting part of the wire mesh. As the cutting blade 7 descends, it compresses the compression spring 16. The compressed spring 16 applies a pushing force to the elastic pressure plate 9. The elastic pressure plate 9 pre-clamps and fixes the wire mesh to be cut. The descending cutting blade 7 contacts the wire mesh and applies pressure, cutting the wire mesh under pressure. The electric push rod 18 drives the U-shaped frame 19 to rise and fall. The rising U-shaped frame 19 lifts the feeding roller 3, which contacts the wire mesh, reducing friction and making it easier to adjust.
