Description

Technical Field

[0001] The utility model relates to the technical field of tobacco manufacturing, in particular to a device for cleaning the inner wall of a leaf shred limiting tube. Background Art

[0002] In the cigarette production process, the cut shreds on the shred line need to be accurately measured and controlled to ensure the stability and consistency of cigarette quality. In the existing technology, the cut shreds are usually fed into the metering tube through a belt conveyor, and the start and stop of the feeding is controlled by the photoelectric sensors on both sides. This design realizes the automatic control of the shred flow to a certain extent, but there are still some problems and shortcomings in practical applications.

[0003] Specifically, since the cut shreds have a certain drop when they fall into the electronic scale belt in the limiting tube, the smoke contained in the shreds is easy to splash onto the organic glass plates on both sides of the limiting tube. Over time, these smoke foams will gradually accumulate and form a certain thickness of sediment. When these sediments accumulate to a certain extent, they will block the emission and reception of the photoelectric detection light sources on both sides, causing the photoelectric sensor to be unable to accurately detect the flow of the shreds.

[0004] Once the photoelectric sensor is disturbed or blocked, its start and stop function of controlling the feeding will be affected, which may lead to the occurrence of feed cut-off. Feed cut-off will not only affect the continuity of cigarette production, but also destroy the flow stability of the electronic scale. In the cigarette production process, the flow stability of the electronic scale is crucial to ensure product quality, and any slight fluctuation may have an adverse effect on the final product quality.

[0005] Therefore, in the current field of cigarette making, when the cut tobacco leaves are fed into the limiting tube, there is a technical problem that the photoelectric sensor fails due to the splashing of tobacco foam, which in turn affects the flow stability of the electronic scale. In order to solve this problem, it is necessary to design a cleaning device for cleaning the inner wall of the tobacco leaf limiting tube to effectively remove the tobacco foam deposits on both sides of the limiting tube, ensure the normal operation of the photoelectric sensor, and thus improve the continuity of cigarette production and the stability of product quality.
