[0021] Specifically in this embodiment, see Figure 1 The overall structure of the thermal transfer film 110 slitting device shown in FIG. 1 is that during use, the thermal transfer film 110 can be unwound, conveyed, and rewound by rotating multiple sets of rollers 101 arranged at corresponding positions of the frame 100 and the drive motor 102 connected to the corresponding rollers 101 and driven to rotate. At the same time, during the conveying process, the cutting assembly 1 on the second frame 120 can be set to cut the thermal transfer film 110 into corresponding strips. The specific structure of the cutting assembly 1 can be seen in FIG. Figure 2 As shown, the plurality of rotating shafts 14 arranged in an array on the tool holder disc 13 can be used to mount different types of annular cutting knives 15 with adaptable rotating shafts 14 structures, such as cutting knives 15 of different specifications and types with different cutting angles and depths or even serrated or corrugated blades of different shapes. Figure 3 As shown in the figure, the structure of the driving component 16 on the corresponding fixed seat 11 and its corresponding installation method, the seat structure 162 of the driving component 16 is slidably set on the slide groove 1121 provided on the fixed seat 11 and is connected to the multiple groups of compression springs 1122 provided in the slide groove 1121. At the same time, the corresponding seat structure 162 is provided with a handle 1621 and the driving component 16 can be moved along the corresponding slide groove 1121 on the fixed seat 11 by the handle 1621. The driving shaft 161 of the driving component 16 and one end of the corresponding rotating shaft 14 adopt the following method: Figure 3 The adaptable plug-in structure shown in the is set, and the tool holder disc 13 on the fixed seat 11 can be rotated according to the use requirements to connect the rotating shaft 14 corresponding to the cutting knife 15 to be used with the driving component 16 on the fixed assembly seat.
