While ensuring the normal use of the combined die-cutting knife roller, the consumable insert type engraving round knife bodies can be maintained and replaced, which is more practical.

[0029] Multiple magnetic components each include a front rotating disc 11 and a rear rotating disc 12. The rear ends of multiple front rotating discs 11 are fixedly connected with synchronous eccentric rods 13 respectively. The rear ends of multiple synchronous eccentric rods 13 are fixedly connected with the front ends of multiple rear rotating discs 12 respectively. Inside multiple front rotating discs 11, a front attracting permanent magnet 14 and a front repelling permanent magnet 15 are fixedly connected respectively. Multiple front attracting permanent magnets 14 match multiple front permanent magnets 8 respectively, and multiple front repelling permanent magnets 15 also match multiple front permanent magnets 8 respectively.

[0030] In summary, the usage process of the combined die-cutting cutter roller integrating the inlaid engraving circular cutter and the magnetic roller is as follows. When in use, first install the combined die-cutting cutter roller integrating the inlaid engraving circular cutter and the magnetic roller at the location where it is required to be used through the front support rotating shaft 24 and the rear support rotating shaft 25. All the inlaid engraving circular cutter bodies are fixedly installed relative to the die-cutting cutter roller body 1. At this time, under the elastic action of the fixing spring 20, the outer mounting seat 18 and the inner mounting seat 19 connected to both ends of the fixing spring 20 move away from each other, prompting the front attracting permanent magnet 14 and the rear attracting permanent magnet 16 to rotate respectively to approach the corresponding front permanent magnet 8 and the corresponding rear permanent magnet 10. Since there is a mutual magnetic attraction between the front attracting permanent magnet 14 and the corresponding front permanent magnet 8, and a mutual magnetic attraction between the rear attracting permanent magnet 16 and the corresponding rear permanent magnet 10, the front insertion frame 7 is inserted into the front insertion slot 3, and the rear insertion frame 9 is inserted into the corresponding rear insertion slot 4, realizing the auxiliary positioning of the arc cutter body frame 5 in the corresponding assembly slot 2. During die-cutting, multiple arc cutter body frames 5 are matched with the die-cutting cutter roller body 1 to form a synchronous movement to realize the rolling cutting of the circular cutter edge 6 relative to the material to be die-cut. When the circular cutter edge 6 is worn and needs to be replaced, only need to rotate the corresponding front rotating disk 11 and the rear rotating disk 12 to make the front repulsive permanent magnet 15 and the rear repulsive permanent magnet 17 rotate respectively to approach the front permanent magnet 8 and the rear permanent magnet 10. Under the action of the magnetic repulsive force, the front insertion frame 7 is pushed out of the front insertion slot 3, and the rear insertion frame 9 is pushed out of the rear insertion slot 4. In this way, the positioning of the arc cutter body frame 5 in the assembly slot 2 can be realized. After replacing the new arc cutter body frame 5, release the rotation drive acting on the front rotating disk 11 and the rear rotating disk 12, and make the front attracting permanent magnet 14 and the rear attracting permanent magnet 16 approach and reset relative to the front permanent magnet 8 and the rear permanent magnet 10 respectively, then the re-installation and positioning of the arc cutter body frame 5 in the assembly slot 2 can be realized, and the replacement operation of the inlaid engraving circular cutter body is completed.
