Description

[0002] In the tobacco industry, filter rod forming and compounding machines are key equipment for producing cigarette filter rods. As an important material for wrapping filter rod tow, the surface properties of the coil directly affect the molding quality of the filter rod and the quality of subsequent cigarettes. There are some problems with the coiling of traditional filter rod forming and compounding machines during use. For example, the bonding force between the coiling paper and the tow is insufficient, which can easily cause the filter rod to become loose, deformed, burst, or fall off during processing, transportation, or use, affecting the smoking quality and appearance quality of cigarettes.

[0003] At present, common methods for treating the surface of coil paper include chemical coating and corona treatment. The chemical coating method requires the use of specific chemical reagents to form a coating on the surface of the coil paper to improve the bonding performance, but the use of chemical reagents may cause environmental pollution and have a potential impact on the taste of cigarettes, and the stability and uniformity of the coating are difficult to accurately control. Although the corona treatment method is relatively simple, the treatment effect is limited, and the machine is large and cannot adapt to the size of the coil paper and the on-site environment.
