[0002] Tipping paper is used to wrap around the outside of cigarette filters and to bond the filter rod to the end of the cigarette rod. With market demand, the production of tipping paper has added a product with sweetener. When printing this product, the last two colors are sweeteners. In order to ensure the stability of the sweeteners during storage and transportation and when they are finally put into use, the tipping paper needs to be wrapped with a layer of white cardboard after production. When wrapping a layer of white cardboard, a cardboard wrapping device is required. There are multiple cylinders installed on the reel of the cardboard wrapping device.

When in use, lubricating oil is applied to these sealing rings to achieve sealing. However, as the number of rotations of the lubricating oil increases, the lubricating effect of the lubricating oil decreases, and new lubricating oil cannot be added in time, resulting in high friction between the rotating shaft and the inner cavity, making the sealing ring and the cavity vulnerable to damage, thereby causing air leakage and affecting the service life of the air sliding ring.
