[0031] As shown in Figure 1 and Figure 2 The slitting machine provided by the utility model, comprising an unwinding roller 1, a winding roller 2 and a cutting mechanism 3, a traction roller 4 is arranged between the unwinding roller 1 and the winding roller 2, the traction roller 4 can drive the composite current collector on the winding roller 2 to the unwinding roller 1, the cutting mechanism 3 is located below the unwinding roller 1, the cutting mechanism 3 comprises a cutter roller 5 and a plurality of cutters 6, the cutter roller 5 is composed of a plurality of cutting assemblies 7, the cutting assembly 7 comprises an expansion part 8, a cutter wall 9 and a cutter holder 10 arranged on the cutter roller 5 in sequence, the cutter 6 is arranged above each cutting assembly 7, and the cutting edge of the cutter 6 is located between the cutter wall 9 and the cutter holder 10, for cutting the composite current collector passing through the cutter roller 5.

[0032] It can be understood that the winding roller 2 is used to wind the cut composite current collector, and the unwinding roller 1 can place the composite current collector on the cutter roller 5 for cutting by the cutter 6.

[0033] Compared with the prior art, the technical scheme of the application can adjust the width of the expansion part according to actual needs, and then adjust the distance between the cutting knives 6, that is, the width of the cutting of the composite current collector can be adjusted, so that different width composite current collectors can be cut on one slitting machine, the cutting efficiency is greatly improved, and multiple slitting machines with different cutting widths are not needed, so the cutting cost of the slitting machine is greatly reduced.

[0034] In an embodiment, the expansion part 8 includes a plurality of expansion bodies, which are sleeved on the roll core (not shown in the figure) of the cutting knife roller 5. It should be noted that the width of each expansion body is the same or different. By setting the width of each expansion body, when it is necessary to adjust the cutting width of the composite current collector, only the number of expansion bodies needs to be adjusted, that is, according to the actual cutting needs, a plurality of expansion bodies are taken off or sleeved on the roll core of the cutting knife roller 5, and then the distance between the two cutting knives 6 is adjusted, so that the cutting width of the composite current collector is adjusted.

The cutting surface 14 can facilitate the cutting knife 6 to enter between the knife wall 9 and the protection part 13, that is, to cut the composite current collector.

[0038] Further, the surfaces of the cutting knife 6 and the knife wall 9 are provided with a chromium plating layer, which can increase the strength of the cutting knife 6 and the knife wall 9, and prevent the cutting knife 6 from being easily cracked or notched during cutting.

[0039] Further, the flattening roller 15 is arranged between the traction roller 4 and the winding roller 2, which can ensure that the composite current collector coming out of the winding roller 2 is smoothly transmitted to the traction roller 4 in a flat form, preventing the occurrence of wrinkle stacking in the composite current collector conveying process.

[0040] Further, the surface of the flattening roller 15 is provided with strip-shaped grooves, which can make the composite current collector expand to both sides when the flattening roller 15 rotates, achieving the effect of flattening to both sides.

[0043] In summary, the slitting machine provided by the utility model can effectively prevent the cutting knife from being damaged due to collision with the knife holder during cutting of the composite current collector, the cutting surface can facilitate the cutting knife to cut the composite current collector between the knife wall and the protection part, the chromium plating layer can increase the strength of the cutting knife and the knife wall, preventing the cutting knife from being easily cracked or notched during the cutting process, the grooves can make the composite current collector expand to both sides, achieving the effect of flattening to both sides, oppositely arranging the cutting knives above the two cutting assemblies can reduce the types of defects after cutting, improving the quality of the cut products. According to the utility model, different width composite current collectors can be cut on one slitting machine by adjusting the width of the expansion part according to the demand, greatly improving the cutting efficiency and reducing the cutting cost of the slitting machine.
