Description

Technical Field

[0001] The utility model belongs to the technical field of tobacco processing, and in particular relates to a secondary wind-selected stem-joining device for a tobacco rolling and joining unit. Background Art

[0002] Tobacco stems in cut tobacco not only affect the appearance of cigarettes, causing quality defects such as punctures, but also negatively impact the smoking experience of consumers. Therefore, during cigarette production, manufacturers must remove stems as much as possible from cut tobacco. Currently, the main processes for removing stems from cut tobacco are the wind-sorting process for cutting tobacco stems and the use of stem separation mechanisms integrated into the rolling and packaging equipment. The stem removal rate in the wind-sorting process can be intuitively calculated based on the amount of stems removed on-site. However, stems removed from the rolling and packaging equipment are collected centrally through negative pressure dust removal ducts, making it impossible to visually measure the number of stems removed. Manual collection and calculation of the amount of stems removed is necessary when necessary. Currently, there are no dedicated stem collection tools. Stem collection is typically done directly under the separation mechanism using sealed bags. This reduces the air flow into the separation mechanism, often leading to air duct blockage, which can cause equipment failures and downtime, impacting operational efficiency. Therefore, the utility model provides a secondary wind-selecting and splicing device for the ZJ17 cutting machine group, which can conveniently and quickly collect and remove the cuttings.
