Description

Technical Field

[0001] The utility model relates to the technical field of tobacco, in particular to a self-cleaning device for a cigarette packet conveying channel. Background Art

[0002] The ZB25 soft box packaging unit consists of the YB25 small box packaging machine, the YB55 small box transparent paper packaging machine, the YB65 strip box paper packaging machine, the YB95 strip box transparent paper packaging machine and the cigarette pack conveying channel. The small box cigarette packs wrapped by the YB25 small box packaging machine are output on the fifth wheel, and enter the YB55 small box transparent paper packaging machine through a long cigarette pack conveying channel for wrapping and forming with transparent paper and draw tape. The exit of the fifth wheel rotates the cigarette pack around the wheel 180° from top to bottom and throws it out. This movement process has a large inertia, which will throw out tobacco and cigarette dust on the cigarette pack conveying channel. In addition, the equipment runs continuously for a long time, and a large amount of cigarette dust will accumulate on the cigarette pack conveying channel, especially at the 90° turn. The cigarette dust will enter the rollers and bearings connected to the conveying channel, reducing the service life of the rollers, bearings and conveying belts, and the equipment fails frequently. When the cigarette pack enters the YB55 small box transparent paper packaging machine and is wrapped with transparent paper, there is often a phenomenon of cigarette dust in the transparent paper, which seriously affects the appearance quality of the cigarette pack and is a serious quality defect. Therefore, it is urgent to find ways to improve and solve the problem.

[0003] At present, a large amount of cigarette dust often accumulates on the cigarette pack conveying channel, and cigarette dust often appears in the transparent paper after the cigarette packs enter the YB55 small box transparent paper packaging machine and are wrapped with transparent paper. The main method is to rely on the regular cleaning and maintenance of the equipment operators, and to use compressed air to blow the cigarette dust on the cigarette pack conveying channel from time to time. This method requires frequent shutdown for dust blowing maintenance, and the equipment shutdown rate is high, which seriously affects the equipment operation efficiency, and will blow the cigarette dust into some cigarette packs, further polluting the cigarette packs, and will also blow the cigarette dust into the rollers and bearings, which will also reduce the service life of the rollers, bearings and conveyor belts.
