After the filter screen is conveyed to the inside of the frame body 4, the second eccentric motor 21 drives the rotating shaft 22 to drive the cutting knife disc 23 to rotate. At the same time, the cutting knife disc 23 is driven to move longitudinally through the linear guide rail 10 to cut the filter screen;

[0022] As a further implementation manner of this embodiment, as Figure 1 and Figure 2 shown, there are adjustment grooves 7 arranged at the middle positions of the tops of both ends inside the groove body 5. Both ends of the limiting roller 8 are movably connected with adjustment rods 13. One end of the adjustment rod 13 penetrates into the inside of the adjustment groove 7. By adjusting the height of the adjustment rod 13 penetrating into the inside of the adjustment groove 7, the distance between the limiting roller 8 and the conveying roller 9 can be adjusted to adapt to air filter screens of different thicknesses, ensuring that the limiting roller 8 can cooperate with the conveying roller 9 to limit the filter screen when the filter screen is conveyed by the conveying roller 9 and guaranteeing the continuity of the conveyance. There are fastening sleeves 15 arranged outside the adjustment rods 13 at both ends of the groove body 5. There is an external thread arranged on the outside of the adjustment rod 13.

[0023] During use, by adjusting the height of the adjustment rod 13 penetrating into the inside of the adjustment groove 7, the distance between the limiting roller 8 and the conveying roller 9 can be adjusted to adapt to air filter screens of different thicknesses, and by screwing the fastening sleeve 15 tightly through threaded connection before and after adjusting the limiting roller 8, the limiting roller 8 can be stabilized;

[0024] As a further implementation manner of this embodiment, as Figures 1-4As shown in the figure, stabilizing components are provided at the bottoms on both sides of the housing 11. The stabilizing components include fixed seats 12. A positioning groove 14 is provided at the bottom end of the fixed seat 12. Between the two sides inside the positioning groove 14, stabilizing pressure wheels 19 are provided, and the stabilizing pressure wheels 19 are arranged at equal intervals between the two sides inside the positioning groove 14. When cutting the filter screen, the filter screen is pressed tightly on the top of the table board 1 by the stabilizing pressure wheels 19, and the stabilizing pressure wheels 19 can move synchronously with the housing 11 and the cutting mechanism driven longitudinally by the linear guide rail 10. At both ends of the inner bottom of the fixed seat 12, through holes 18 are provided. At both ends of the top of the positioning groove 14, movable guide rods 17 are provided, and the movable guide rods 17 are symmetrically arranged at the top of the positioning groove 14. The top ends of the movable guide rods 17 penetrate through the inside of the through holes 18. A limiting block 16 is provided at the top end of the movable guide rod 17. A return spring 20 is sleeved outside the movable guide rod 17 between the top of the positioning groove 14 and the bottom end of the fixed seat 12. The top of the return spring 20 is fixedly connected to the bottom of the fixed seat 12, and the bottom of the return spring 20 is fixedly connected to the top of the positioning groove 14. When the cutting mechanism moves to cut the filter screen, the stabilizing pressure wheels 19 inside the positioning groove 14 are pushed by the elastic force of the return spring 20 to always fit and press the filter screen tightly, thus effectively preventing the filter screen from being wrinkled during cutting and affecting the cutting quality;

[0025] When cutting the air filter screen, the filter screen is pressed tightly on the top of the table board 1 by the stabilizing pressure wheels 19, and the stabilizing pressure wheels 19 can move synchronously with the housing 11 and the cutting mechanism driven longitudinally by the linear guide rail 10. When the cutting mechanism moves to cut the filter screen, the stabilizing pressure wheels 19 inside the positioning groove 14 are pushed by the elastic force of the return spring 20 to always fit and press the filter screen tightly, and the return spring 20 is limited and reset by the movable guide rod 17;

[0026] Specific working principle:

[0027] When using the filter screen cutting device, first adjust the height of the adjusting rod 13 penetrating inside the adjusting groove 7 according to the thickness of the filter screen to be cut, so as to adjust the distance between the limiting roller 8 and the conveying roller 9. After adjusting the front and back of the limiting roller 8, tighten the fastening sleeve 15 by screwing to fix the limiting roller 8 firmly. Subsequently, pass the filter screen to be cut through between the conveying roller 9 and the limiting roller 8. The conveying roller 9 is driven by the first eccentric motor 6 to drive the filter screen to be conveyed at a fixed distance. At the same time, the limiting roller 8 is used to cooperate to limit the filter screen to ensure its continuous conveying. After the filter screen is conveyed at a fixed distance to the inside of the frame body 4, the second eccentric motor 21 drives the rotating shaft 22 to drive the cutting knife disc 23 to rotate, and at the same time drives the cutting knife disc 23 to move longitudinally to cut the filter screen through the linear guide rail 10. At the same time, the stabilizing pressure wheels 19 inside the positioning groove 14 are pushed by the elastic force of the return spring 20 to always fit and press the filter screen tightly. The filter screen is pressed tightly on the top of the table board 1 by the stabilizing pressure wheels 19. When cutting, if the filter screen is wrinkled, it will affect the cutting effect, so as to carry out continuous and stable filter screen cutting work.
