Description
Technical Field
The invention relates to the technical field of tobacco processing, in particular to a feeding roller, a cleaning method thereof and tobacco processing equipment.
Background
In the process of producing tobacco according to batches, card changing and batch changing are important links, which are not only related to the control quality of the production process and the quality of the final product, but also closely related to the production efficiency. When the cards are changed and the batches are changed, if each rhythm is properly controlled, seamless connection is achieved, invalid production time can be reduced or even eliminated, and production efficiency is improved.
For the process of loosening the tobacco flakes by the roller, the time from the end of feeding of the roller to the complete emptying of the material and then the next secondary production is the time for changing the brand and the batch of the process. During normal production, under the condition of keeping the flow unchanged, the time for replacing the license plate and the batch by the roller depends on the emptying time of the residual materials of the roller, the emptying time of the residual materials is shortened or even eliminated, and the production efficiency of the process can be improved.
At present, the emptying time of the residual materials of the roller is relatively long, and the remedial measures of manual intervention are adopted in the related art to shorten the time for changing the cards and the batches. Specifically, after the main material in the roller is emptied, the residual material of the subsequent thin drawing is fed into the roller by workers for cleaning. The method has the disadvantages that the manual cleaning efficiency is low; workers enter and exit the roller, the opening and closing of the roller door consumes some time, and the preparation of the next batch production after the rollers are closed also needs to be made, and certain time also needs to be consumed; the internal temperature of the roller reaches 55 ℃ just after the roller production is finished, and the high-temperature working environment is a great test for cleaners; there may be many unsafe factors in performing the cleaning operation inside the drum.
It is noted that the information disclosed in this background section is only for enhancement of understanding of the general background of the invention and should not be taken as an acknowledgement or any form of suggestion that this information constitutes prior art already known to a person skilled in the art.
