A through hole is provided at the center of the slitting circular knife body. A cross welding head is inserted into the through hole, and the cross welding head is fixed to the inner wall of the through hole and divides the through hole into two symmetric arc-shaped slots. Plug rods are inserted into the two arc-shaped slots, and the two plug rods jointly clamp the cross welding head and fix the slitting circular knife body.

[0006] Preferably, the two plug rods are symmetrically arranged, and the mutually close sides of the two plug rods are flat, and the mutually far ends of the two plug rods are arc-shaped.

[0007] Preferably, the upper and lower ends of the cross welding head are fixedly welded to the inner wall of the through hole. Reinforcing pieces are fixed on both sides of the slitting circular knife body, and the reinforcing pieces are welded to the cross welding head.

[0008] Preferably, a stud is provided at the end of one of the plug rods, and the stud is inserted into a jack provided on the other plug rod and a locking nut is screwed at the end of the stud.

[0009] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0010] For the slitting circular knife for foil materials of the utility model, a cross welding head is welded on the slitting circular knife. By inserting two plug rods into the middle of the slitting circular knife and clamping and fixing the cross welding head, all the slitting circular knife bodies thereon are fixed. Compared with the existing slitting circular knife, the assembly is simpler and more efficient. Description of the Drawings

[0015] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0016] Please refer to Figures 1 - 3 , a foil slitting circular knife, including a slitting circular knife body 1, a through hole 2 is provided at the center of the slitting circular knife body 1, a cross welding head 3 is inserted into the through hole 2, and the cross welding head 3 is fixed to the inner wall of the through hole 2 and divides the through hole 2 into two symmetric arc-shaped slots. Plug rods 5 are inserted into the two arc-shaped slots, and the two plug rods 5 jointly clamp the cross welding head 3 and fix the slitting circular knife body 1. After adjusting the position of the slitting circular knife body 1 on the plug rods 5, the two plug rods 5 clamp each other to fix all the slitting circular knife bodies 1 thereon. Compared with the existing assembly of slitting circular knives, it is more simple and efficient.

[0017] Preferably, the two plug rods 5 are symmetrically arranged, and the mutually approaching sides of the two plug rods 5 are flat, which is convenient for clamping the slitting circular knife body 1. The mutually distant ends of the two plug rods 5 are arc-shaped, which is convenient for fitting with the slots.
