Description

Technical Field

[0001] This utility model relates to the field of cigarette equipment technology, and in particular to a duct cleaning device for a leaf-moistening machine. Background Technology

[0002] The task of the tobacco leaf re-drying production line is to process the raw tobacco entering the re-drying workshop through processes such as leaf and stem separation, re-drying of leaves and stems, and pre-pressing and packaging, into finished leaves and stems of a certain weight and packaging form according to quality indicators. With the widespread use of sheet tobacco, tobacco leaf re-drying has become an indispensable and important part of cigarette production.

[0003] To reduce the amount of debris generated during the threshing process, a leaf-humidifying machine is typically used to heat and humidify the tobacco leaves. The working principle of the leaf-humidifying machine is to inject hot, moist steam into the cylinder through nozzles. The steam circulates inside the machine through ducts, ensuring thorough contact between the steam and the tobacco leaves, increasing their moisture content and softening them. However, the transport of the tobacco leaves within the humidifying machine also generates some debris. This debris easily adheres to the inner wall of the duct in the hot and humid environment. If the inner wall of the duct is not cleaned regularly, the debris will ferment and produce an unpleasant odor, affecting the quality of the re-dried tobacco leaves and failing to meet process quality standards. Therefore, the inner wall of the duct needs to be cleaned regularly.

[0004] In existing technologies, duct cleaning is typically done manually. However, manual cleaning is slow, inefficient, and results in prolonged downtime. Furthermore, manual cleaning cannot thoroughly clean the inner walls of the ducts, leaving blind spots. Therefore, there is an urgent need for a duct cleaning device with a leaf-lubricating machine to solve these problems. Utility Model Content
