Description

Technical Field

[0001] The utility model relates to the field of tobacco operations, in particular to a stem cleaning device for a steel bar screen. Background Art

[0002] Tobacco stems are the coarse and hard veins of tobacco leaves, accounting for about 25% to 30% of the leaf weight. As one of the main finished products of leaf threshing and redrying enterprises, finished long stems have a high use value in tobacco industry enterprises. Tobacco stems are the main component of some cigarettes and papermaking reconstituted tobacco leaves, and play an important role in reducing the release of harmful tobacco components in cigarette products and reducing the cost of cigarette products. With the rapid development of tobacco stem shred technology, tobacco stems play an increasingly important role in the cigarette process, and the quality of stem shreds directly affects the quality of finished cigarettes.

[0003] After re-roasting, tobacco stems mainly include the following types of stems, namely regular short stems, regular long stems, bent stems, stem foam and broken stems.

[0004] In the current prior art, the processing process of finished long stems is as follows: after leaf beating, wind separation, and stem re-roasting, the stems are transported to the stem screening and processing equipment by air conveying. In the stem screening process, the stems in the tobacco stems are screened out by a steel screen, the leaf diameter, stem skin, and stem foam in the tobacco stems are screened out by a fine stem screen, and finally the short stems are screened out by a long and short stem screen, thereby screening out long stems with a length greater than 20 mm. In actual production, this process flow and the screening and processing equipment used in it are very likely to cause the mesh of the long and short stem screen to be blocked by the stems due to the incomplete removal of the stems, which further causes the long and short stems to be screened out incompletely for the short stems and long stems, and ultimately affects the long stem rate of the long stems.

[0005] To solve this problem, the existing technology mostly uses manual cleaning to remove the stems on the steel screen. However, manual cleaning is unstable, and a large number of stems fall under the steel screen, affecting the screening effect of the long and short stems screen, and ultimately affecting the long stem rate of the finished product; moreover, manual cleaning is prone to violent operation, which can damage the steel screen.
