Description

Technical Field

[0001] The utility model relates to a drying device, in particular to a tipping paper circulating drying device. Background Art

[0002] Tipping paper is a special paper, usually used as a packaging material for cigarettes. It is named after its appearance is similar to the outer skin of the tarragon plant. After printing, this paper is usually used to wrap the outside of the cigarette filter, which not only plays a decorative role, but also increases the service life of the filter. The characteristics of tipping paper are that it has certain water resistance and wet strength. At the same time, it must also meet food hygiene standards, and the printing ink and coating used are non-toxic. This kind of paper is relatively soft and easy to curl, so it is particularly suitable for making cigarette filter packaging. After the tipping paper is produced, the surface of the tipping paper needs to be dried. The existing tipping paper circulation drying device generally uses hot air flow for drying. The air outlet of the air flow is generally only set on one side, so that the top and bottom of the tipping paper are heated unevenly. At the same time, the air pumped to the surface of the tipping paper is not filtered, and the air carries impurities such as dust, which is easy to pollute the wet tipping paper surface. Before drying the tipping paper, no extrusion is performed to discharge the clear water, which leads to low drying efficiency and high energy consumption, which is not conducive to energy saving and environmental protection.
