Description

Technical Field

[0001] This utility model relates to the field of slitting blade technology, specifically a slitting machine cutting blade and mounting tool. Background Technology

[0002] Slitting blades are one of the important components of slitting machines. Slitting machine blades are mainly used for cutting, rolling, and slitting the direction of materials, such as paper and film.

[0003] Slitting materials will produce burrs and a large amount of waste such as slitting powder.

[0004] Existing technologies involve slitting structures on slitting machines, such as CN202322861204.1, a slitting machine blade fixing mechanism used to adjust the spacing of the slitting blades on the shaft. Another example is CN201320455579.1, a slitting machine and its chip removal device, which uses air-blowing pipes on the cutting device for air-blowing chip removal. However, firstly, the slitting blades use traditional disc slitting blades, which generate a large amount of heat at the cutting contact, causing thermal deformation of many materials, such as thin films. Secondly, most cutting structures separate heat dissipation and chip removal, resulting in unstable chip removal or heat dissipation effects and requiring numerous external structures for installation, leading to cumbersome installation and maintenance.

[0005] To address these issues, we provide a slitting machine cutting blade and mounting tool. Utility Model Content
