Description

Technical Field

[0001] This utility model relates to the field of tobacco manufacturing equipment technology, specifically to a device for improving the efficiency of a cutting blade. Background Technology

[0002] In the composite filter rod molding process, rods of various materials and lengths need to be precisely cut before being composited and rolled into shape. The cutting efficiency and precision of the rods are key factors determining the final quality of the formed filter rods.

[0003] Given that the composite filter rod forming equipment operates at high speeds, the slitting blades need to cut the rods at extremely high frequencies. During continuous high-speed operation, the blades experience a significant temperature rise due to friction, leading to a decrease in their mechanical properties and a substantial reduction in their lifespan. Furthermore, the slitting process generates trace amounts of debris and adhesive residue from rods of different materials, resulting in rough cut surfaces, burrs on the cut edges, and other surface defects, significantly reducing the equipment's slitting efficiency and the quality of the cut filter rods.
