The die-cutting coil 6 passes through the cutting mechanism 1, the pre-separating mechanism 2 and the separating mechanism 3 in sequence, the cut finished product coil 61 is wound onto the finished product roller 5, and the cut waste coil 62 is wound onto the waste roller 4.

[0023] like Figure 1As shown, the cutting mechanism 1 is a roller die cutting machine, including a frame 11, which is a rectangular frame, and a pressure roller 12 is fixedly installed on the lower side of the frame 11, and the two ends of the pressure roller 12 are connected to the frame 11 through bearings. A motor bracket is installed at the rear end of the frame 11, and a driving motor 14 is fixedly installed on the motor bracket. One end of the pressure roller 12 extends out of the frame 11 and is connected to the driving motor 14 through a gear transmission assembly.

The structure and principle of the roller die cutting machine are all prior art, and will not be described here.

[0024] like Figure 2-5 As shown, the pre-separation mechanism 2 includes a pre-separation roller 21, a connection plate 22, a connection seat 23 and a pre-separation top block 24. Two circular connection plates 22 are respectively welded and fixed at both ends of the pre-separation roller 21, and the connection plates 22 are coaxially arranged with the pre-separation roller 21. Two groups of arc-shaped slots 221 are respectively opened on the connection plates 22, each group of arc-shaped slots 221 is surrounded by a circle, and the two groups of arc-shaped slots 221 are concentrically arranged with the pre-separation roller 21.

[0025] like Figure 2 , Figure 4 As shown, the connection seat 23 is a long strip structure, and eight connection seats 23 are evenly installed between the two connection disks 22. A connection groove 231 with a dovetail cross-section is provided on the upper side of the connection seat 23, and the connection groove 231 is parallel to the length direction of the connection seat 23. The lower surface of the connection seat 23 is an arc that matches the outer diameter of the connection disk 22, and a connection frame 232 is fixed at both ends of the lower side of the connection seat 23, and the lower end of the connection frame 232 is an arc that matches the outer diameter of the pre-separation roller 22.

Two connection holes 2321 are provided on the connection frame 232, and the connection holes 2321 are located on the circumference of the arc-shaped slot hole 221. When in use, the locking piece is passed through the arc-shaped slot hole 221 and connected to the connection hole 2321, so as to achieve the locking of the connection seat 23 and the connection disk 22. Preferably, the locking member is a bolt, and the connecting hole 2321 is a threaded hole.
