AI Technical Summary

Technical Problem

The creasing technology of existing digital die-cutting machines cannot effectively handle situations where the graphics and text on packaging boxes such as paper boxes are on the outside and the creases are folded inwards, which makes the creases prone to cracking and makes it difficult to replace the cutter after it is damaged.

Method used

A forward and reverse indentation and cutting device with quick-change of multiple cutting tools was designed, including a die-cutting carriage and a linkage slide. The linkage slide is equipped with a mounting slot for quick disassembly and replacement of indentation parts and blade pads, supporting forward and reverse indentation and cutting. The device can be changed in seconds through the mounting slot and the material pick-up port.

Benefits of technology

It enables back-crease treatment of cardboard boxes and other materials, preventing creases and cracking on graphic surfaces, and the tool replacement is simple and quick, reducing replacement time.

Abstract

The utility model discloses a positive and negative indentation cutting device capable of quickly replacing various cutters, which comprises a die cutting trolley movably mounted on a die cutting device, and an indentation cutter and / or a cutting cutter mounted on the die cutting trolley, and is characterized by further comprising a linkage sliding table arranged opposite to the die cutting trolley, the linkage sliding table is at least provided with an indentation piece and / or a cutter pad, wherein the indentation piece is matched with an indentation cutter on the die cutting trolley to machine positive and negative traces on the thin material, and the cutter pad plays a supporting role when the cutting cutter on the die cutting trolley cuts the thin material. The linkage sliding table is provided with a mounting groove used for rapidly disassembling, assembling and replacing the creasing piece and / or the cutter pad. The paper and thin materials can be subjected to forward and backward bidirectional creasing, step rolling and the like, so that back creasing can be carried out when paper boxes with images and texts and the like are subjected to creasing, and creases on the surfaces of the images and texts cannot burst.
