A cutting roller 4 is provided on the outer side of the cutting roller 4. There is a cutting shear 12. A servo motor 10 is set at the middle position of the rear end of the frame 1 near the bottom. The rear end of the rotating shaft 9 is connected to the output end of the servo motor 10. The servo motor 10 drives the rotating shaft 9 to drive the cutting roller 4 and the cutting shear 12 to rotate and cut the non-woven fabric conveyed by the conveyor table 2. A stable bearing seat 5 is set at the middle position of the front end of the bottom inside the frame 1. The front end of the rotating shaft 9 is inserted into the top of the inner side of the stable bearing seat 5. The stable bearing seat 5 supports and stabilizes the rotating shaft 9 to ensure that the cutting roller 4 rotates stably.

[0022] As a further implementation of this embodiment, such as Figure 1 , Figure 3 and Figure 4 As shown, the outer side of the cutting roller 4 is provided with mounting slots 11, which are arranged at equal intervals on the outer side of the cutting roller 4. The inner side of the cutting blade 12 is provided with mounting plate 16, which is inserted into the interior of the mounting slot 11. The two ends of one side of the mounting plate 16 are provided with connecting studs 17, which are symmetrically arranged on one side of the mounting plate 16. The connecting studs 17 penetrate through the interior and exterior of the mounting slot 11. The outer side of the connecting studs 17 on the outer side of the cutting roller 4 is provided with fastening nuts 15. After the mounting plate 16 is inserted into the mounting slot 11, the fastening nuts 15 are fitted onto the outer side of the connecting studs 17 and tightened to achieve the purpose of securely installing the cutting blade 12 on the outer side of the cutting roller 4. By adjusting the number and spacing of the cutting blades 12, non-woven fabrics of different widths can be cut according to the cutting requirements, ensuring uniform cutting dimensions and facilitating the disassembly and replacement of the cutting blades 12, making it highly feasible.

[0023] When in use, insert the mounting plate 16 into the mounting slot 11, and at the same time, the connecting stud 17 passes through the inside and outside of the mounting slot 11. Then, put the fastening nut 15 on the outside of the connecting stud 17 and tighten it, so that the cutter 12 is securely installed on the outside of the cutting roller 4. By adjusting the number and spacing of the cutter 12, non-woven fabrics of different widths can be cut according to the cutting requirements, and the cutter 12 can be easily disassembled and replaced.

[0024] As a further implementation of this embodiment, such as Figure 1-4As shown, a safety protection component is provided on the outside of the cutting roller 4.

[0025] When in use, the isolation cover 3 is attached to the outside of the cutting roller 4, and the mounting plate 14 is inserted into the inside of the positioning slot 7. The front end of the isolation cover 3 is supported by the stabilizing bracket 8, so that the isolation cover 3 can be installed outside the cutting roller 4 for isolation and protection.

[0026] Specific working principle:

[0027] When using the nonwoven fabric cutting equipment, first adjust the spacing of the cutting blades 12 according to the required cutting speed and insert the mounting plate 16 into the corresponding mounting slot 11. Simultaneously, the connecting stud 17 passes through the inside and outside of the mounting slot 11. Then, the fastening nut 15 is fitted onto the outside of the connecting stud 17 and tightened, thus securing the cutting blades 12 at a fixed distance to the outside of the cutting roller 4. Next, the isolation cover 3 is placed over the outside of the cutting roller 4, and the mounting plate 14 is inserted into the positioning slot 7. Finally, the stabilizing mechanism is secured. The fixed bracket 8 supports the front end of the isolation cover 3, which can be installed outside the cutting roller 4 for isolation and protection. After the equipment is started, the non-woven fabric is transferred by the conveyor table 2 and the flattening roller 6 is used to flatten the non-woven fabric. At the same time, the servo motor 10 is started to drive the rotating shaft 9 to rotate the cutting roller 4 and the cutting shears 12 to cut the non-woven fabric conveyed by the conveyor table 2. The rotating shaft 9 is supported by the stable bearing seat 5 to ensure that the cutting roller 4 rotates stably, thereby performing safe, stable and accurate non-woven fabric cutting operations.
