Description

Technical Field

[0001] This utility model relates to the field of die-cutting equipment technology, specifically a rotary cutter assembly for a die-cutting equipment. Background Technology

[0002] Die cutting is a process that uses a die-cutting plate to cut printed materials or other paper products according to a pre-designed pattern, so that the shape of the printed materials is no longer limited to straight edges and right angles. It is a forming process that uses pressure to cut printed materials or other plate-shaped blanks into the required shape or cut marks.

[0003] A high-performance rotary die-cutting tool, CN202122008884.3, can block splashed waste material, directing it into a collection tank. Under the action of a suction pump, the waste is then collected in a collection box, preventing large amounts of waste from scattering on the worktable and causing manual cleaning hassles. It also prevents splashed waste from entering the environment, thus avoiding potential safety hazards and improving the tool's practicality. However, it has shortcomings. Adjusting the cutter is difficult, and replacing the cutter requires disassembling the entire rotating shaft, which is cumbersome and affects production efficiency. Furthermore, the fixing structure between the cutter and the rotating shaft lacks stability, easily loosening over time, leading to decreased cutting accuracy and poor heat dissipation. Therefore, a rotary cutter assembly for die-cutting equipment is needed to solve these problems. Utility Model Content
