[0055] In one possible implementation, please refer to Figure 3 The first sliding groove 210 includes at least two parallel first sliding grooves 210 .

[0056] In this embodiment, the first sliding groove 210 is designed to include at least two parallel first sliding grooves 210. The main purpose of such design is to provide stable guidance and support for the cutter assembly 300. When the cutter assembly 300 slides along the first sliding groove 210, the two parallel first sliding grooves 210 can ensure its stability and accuracy during the movement.

[0057] In one possible implementation, please refer to Figure 3 and Figure 5 The cutter support platform 200 includes a second positioning assembly 230 for temporarily fixing the slitting knife cart 20 for transporting the cutter assembly 300.

[0058] In this embodiment, the cutter support platform 200 also has a second positioning assembly 230. When replacing the cutter 330, the second positioning assembly 230 and the slitting knife cart 20 for transporting the cutter assembly 300 can be temporarily fixed. At this time, the slitting knife cart 20 can remain stable relative to the cutter support platform 200 and will not slide or tilt due to movement or operation, thereby ensuring the safety and stability of the cutter assembly 300 during transportation and replacement.

[0059] In one possible implementation, please refer to Figure 6 The driving assembly includes a driving motor and a first engaging portion 110 connected to the driving motor.

[0060] The cutting roller 320 is provided with a second engaging portion 321 at one end, and the first engaging portion 110 and the second engaging portion 321 match in shape. When the cutting knife assembly 300 is located in the working position, the first engaging portion 110 and the second engaging portion 321 engage with each other, and the motor drives the first engaging portion 110 to rotate, thereby driving the cutting knife 330 on the cutting roller 320 to work.

[0061] In this embodiment, the shape of the second interlocking portion 321 matches the first interlocking portion 110. When the cutter assembly 300 is accurately moved to the working position through the first sliding groove 210, the first interlocking portion 110 and the second interlocking portion 321 will be closely interlocked together. When the second interlocking portion 321 is interlocked with the first interlocking portion 110, the driving motor can further drive the cutter roller 320 connected to the second interlocking portion 321 to start rotating through the first interlocking portion 110. As the cutter roller 320 rotates, the cutter 330 above will start working to perform tasks such as cutting or slitting. This design not only makes the connection between the driving assembly and the cutter roller 320 more stable and reliable, but also makes the replacement of the cutter assembly 300 convenient. The removal and installation of the cutter roller 320 can be completed by separating or interlocking the first interlocking portion 110 and the second interlocking portion 321.

[0062] In one possible implementation, please refer to Figure 1 The narrow strip slitting device 10 also includes a plurality of drive rollers and / or winding rollers 322 , all of which extend in a direction away from the machine and are parallel to the cutting roller 320 .

[0063] For example, when using the narrow-band slitting device 10 provided in this embodiment to slit the material to be cut, a plurality of the materials to be cut can be first connected through the connecting component of the feeding assembly, and then pulled to the adjusting component by the driving roller 322 of the feeding assembly. The adjusting component can be used to adjust the plane where the material to be cut is located to be tangent to the cutter 330 blade of the cutter assembly 300, and then the cutter assembly 300 cuts the material to be cut to obtain a plurality of narrow bands, and finally the plurality of narrow bands are wound up by the winding roller.

[0064] This application also provides a cutter replacement method, please refer to Figure 7 , applied to the narrowband slitting device 10 described in any one of the above, the method includes the following steps.
