Technical Field

[0001] The utility model relates to the technical field of tool assembly tooling, in particular to a die-cutting tool device which is convenient for replacing a tool head. Background Art

[0002] The die-cutting machine is also called a die-cutting machine, a cutting machine, or a CNC punching machine. It is mainly used for die-cutting of some corresponding non-metallic materials, self-adhesive stickers, EVA, double-sided tape, electronics, mobile phone pads, etc. The die-cutting machine can use steel knives and other die-cutting tools to apply a certain amount of pressure to cut printed products or cardboard. It is an important equipment for post-printing packaging processing and molding.

[0003] The current die-cutting machines all need to use tooling to fix the die-cutting tools. However, during use, the die-cutting tools need to be replaced in time as they wear out. However, the existing tooling structure is fixed, and it is cumbersome to disassemble and replace the die-cutting tools.

[0004] The existing Chinese patent with the announcement number CN220593409U discloses a die-cutting tool assembly tool for a die-cutting machine, including a die-cutting tool body. The assembly tool includes a fixing positioning plate, on which the die-cutting tool body is detachably mounted, and the fixing positioning plate is installed inside a mounting seat and can be raised and lowered in the vertical direction of the mounting seat to adjust the die-cutting height.

[0005] With respect to the above-mentioned and existing related technologies, the inventors believe that the following defects often exist: when the die-cutting tool is in use, due to the static electricity generated by the tool during rapid cutting and other reasons, the die-cut paper debris is adsorbed on the knife plate, thereby affecting the die-cutting effect again, and improvement is needed; therefore, in order to solve the above-mentioned problem, a die-cutting tool device that is easy to replace the knife head is proposed.
