[0024] like Figure 2-5As shown, in this embodiment, a sliding groove 201 is opened on the inner side of the die-cutting guide frame 2, and a reciprocating screw 202 is installed inside the sliding groove 201. A lifting guide block 401 is installed between the die-cutting base 5 and the tool storage mechanism 4 and the reciprocating screw 202. The tool storage mechanism 4 and the die-cutting base 5 are engaged and rotated with the reciprocating screw 202 through the lifting guide block 401. One end of the reciprocating screw 202 is located on the upper surface of the die-cutting guide frame 2 and a die-cutting motor 3 is installed.

At the same time, the installation position of the blade 405 on the outside of the tool roller 404 corresponds to the ratchet position on the outside of the ratchet gear 406. Then, by controlling the position of one ratchet tooth to rotate, the displacement of the blade 405 is controlled, and the purpose of tool changing without stopping the machine is achieved. At the same time, the blade 405 is inserted into the socket 411 as a whole by the pin 409, and then the positioning screw 410 is used to install and limit the positioning screw hole 408 at the end of the blade 405, so that the purpose of replacing and installing blades 405 of different models on the outside of the tool roller 404 can be achieved.
