Description

Technical Field

[0001] The utility model relates to the technical field of cigarette making equipment, in particular to a distance-fixing device. Background Art

[0002] In the cigarette industry, cavity filters and cavity filler filters are two key materials, primarily responsible for reducing the amount of harmful substances in smoke and enhancing the sensory quality of cigarettes. Cavity filters utilize their unique internal cavity design to effectively intercept harmful substances in smoke, such as tar and nicotine, thereby reducing the potential health risks of smoking. In contrast, cavity filler filters incorporate specialized materials such as activated carbon and nanoparticles within the cavity to enhance the adsorption of harmful substances.

[0003] Ensuring consistent spacing between the cavity segments in both types of filter rods is a key quality criterion. Currently, various cavity spacing devices are available on the market, including adapter discs, spiral drums, and toothed belts. However, our design offers a simple structure, flexible adjustment, and low cost. This device is not only easy to operate, but also effectively ensures uniformity and consistency in the filter rods.
