[0002] Finished tobacco boxes are equipment for storing finished tobacco. They can store finished tobacco in a closed environment for purification and balance the moisture content of the tobacco. During the packing process of finished tobacco, due to the existing structure of the packing equipment, a small amount of tobacco falls on the edges around the tobacco box and ash adheres to the surface of the box during the packing process; and the existing finished tobacco boxes have no effective cleaning methods after packing, resulting in the tobacco and ash on the outer surface of the box not being cleaned. The tobacco on the edge of the tobacco box is exposed to the outside air for a long time, which will cause the loss of moisture and aroma. The mixing of qualified tobacco in the process of turning the box and unloading the material will lead to a decrease in the quality of the finished tobacco. Utility Model Content

DETAILED DESCRIPTION

[0021] In order to make the purpose, technical solution and advantages of the embodiments of the utility model clearer, the technical solution in the embodiments of the utility model will be clearly and completely described below in combination with the embodiments of the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] Please refer to Figures 1 to 3 The present embodiment provides an automatic cleaning device for the outer surface of a finished tobacco box, comprising at least one cleaning unit, each cleaning unit comprising two cleaning brackets 2 arranged on both sides of a finished tobacco box conveying passage 1, on which vertically extending cleaning rollers 3 are rotatably mounted respectively, and the two cleaning rollers 3 are arranged on both sides of the finished tobacco box conveying passage 1, and the cleaning roller 3 comprises a cleaning roller shaft 4 and a cleaning roller sleeve 5 which are fixedly matched inside and outside, and the cleaning roller sleeve 5 is axially fixed on the cleaning roller shaft 4 by two downward fixed retaining rings 6, and the upper and lower ends of the cleaning roller shaft 4 extend out of the upper and lower ends of the cleaning roller sleeve 5 to form shaft heads, and the shaft heads of the upper and lower ends of the cleaning roller shaft 4 are rotatably supported on the cleaning bracket 2 by the second bearing seat 7 respectively. A driving bracket 8 is arranged across the tops of the two cleaning brackets 2, and a driving mechanism is mounted on the driving bracket 8, and the two cleaning rollers 3 are driven to rotate around their respective axis lines by the driving mechanism, and the two cleaning rollers 3 rotate in opposite directions.

[0023] The driving mechanism includes a driving motor 9, a commutator 10, two guide rods 11, and two bevel gear pairs. The input end of the commutator 10 is coaxially connected to the output end of the driving motor 9 through a coupling 12. The two output ends of the commutator 10 are respectively connected to one end of the two guide rods 11. The other ends of the two guide rods 11 are respectively connected to the upper ends of the two cleaning rollers 3 through two bevel gear pairs. The guide rods 11 are supported for rotation by two first bearing seats 16 fixed on the driving bracket 8. Each bevel gear pair includes a meshing active bevel gear 13 and a driven bevel gear 14. The active bevel gear 13 is fixed on the guide rod 11, and the driven bevel gear 14 is fixed on the cleaning roller 3. The conversion of the transmission direction is realized through the bevel gear pair.

[0024] A plurality of brushes 15 are arranged on the outer roller surface of each cleaning roller 3, and the distribution form of the plurality of brushes 15 on the outer roller surface of the cleaning roller 3 is as follows:

[0025] Multiple groups of brush assemblies are distributed circumferentially along the outer roller surface of the cleaning roller 3, and each group of brush assemblies includes a plurality of brushes 15. The arrangement trajectory of the plurality of brushes 15 in each group of brush assemblies is a cylindrical spiral trajectory based on the central axis of the cleaning roller 3, and the plurality of brushes 15 in each group of brush assemblies are equidistantly spaced on the corresponding cylindrical spiral trajectory.

[0026] In this embodiment, four groups of brush assemblies are distributed along the circumference of the outer roller surface of the cleaning roller 3 , and each group of brush assemblies includes 27 brushes 15 .

[0027] In this embodiment, the automatic cleaning device includes two cleaning units, which are respectively installed at two perpendicular finished tobacco box conveying passages 1, so that full coverage cleaning of the four sides of the finished tobacco box 17 can be achieved.

[0028] During operation, the finished tobacco box 17 is transported through the finished tobacco box conveying channel 1. When the finished tobacco box 17 passes through the cleaning unit, the surfaces on both sides of the finished tobacco box 17 are cleaned by the bristles on the two counter-rotating cleaning rollers 3 of the cleaning unit. The rotation directions of the two cleaning rollers 3 located on both sides of the finished tobacco box 17 are opposite to the movement direction of the finished tobacco box 17 in the tangent direction of the contact surface of the finished tobacco box 17, respectively, ensuring smooth and effective automatic cleaning. At the same time, since multiple cleaning bristles are distributed in a cylindrical spiral line on the surface of the cleaning roller 3, when the cleaning roller 3 cleans the finished tobacco box 17, it has an upward force on the cleaned tobacco and ash, and can throw the cleaned tobacco and ash upward in a spiral shape to prevent them from falling down and reattaching to the surface of the finished tobacco box 17, thereby ensuring the cleaning effect.

[0029] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
