Description

Technical Field

[0001] The utility model belongs to the technical field of cigarette production equipment, and in particular relates to a cleaning device suitable for a paper cutting wheel of a cigarette packaging machine. Background Art

[0002] The YJ218 paper cutting wheel cleaning brush of the loading and unloading machine has no power source. It transmits power through the external friction force with the surface of the paper cutting wheel. The paper cutting wheel rotates clockwise, driving the cleaning brush to rotate counterclockwise to clean the surface of the paper cutting wheel. In actual production, since the linear speed direction of the paper cutting wheel and the cleaning brush at the tangent point, that is, the moment of contact and cleaning, is consistent, and the cleaning brush has no power source, the cleaning torque of the cleaning brush is small, and the cleaning effect on the surface of the paper cutting wheel is poor. On the one hand, glue scale accumulates on the surface of the paper cutting wheel, affecting the cutting of the tipping paper and causing wrinkles in the splicing of the tipping paper; on the other hand, waste tipping paper adheres to the surface of the paper cutting wheel and cannot be removed in time, causing the problem of multiple splicing of the tipping paper. Therefore, it is necessary to improve the problems existing in the above-mentioned paper cutting wheel cleaning brush device. Utility Model Content
