Description

Stem sorting unit

Technical Field

The invention relates to the field of tobacco machinery, in particular to a cut stem sorting device.

Background

The cigarette is one kind of tobacco product, and is produced through stoving tobacco leaf, shredding, eliminating tobacco stem and packing in paper roll. In the cigarette making process, tobacco shred stem removal is an extremely important process, and specifically, the made tobacco shreds contain partial tobacco stems, and the tobacco stems are removed as clean as possible before being rolled into cigarette branches, because the tobacco stems are harder than the tobacco shreds, the tobacco stems cannot be bent along with cigarette paper, and the cigarette paper can be punctured when the tobacco stems are wrapped in cigarette strips, so that unqualified products are caused; meanwhile, the tobacco stems have high specific gravity, so that the physical indexes of cigarettes are influenced; in addition, the stem may change the taste of the cigarette, and thus must be completely separated from the cut tobacco. Therefore, the removal of the stem from the cut tobacco is extremely important.

In order to realize automation of removing tobacco stems from tobacco shreds, a tobacco factory usually adopts a special stem sorting device, currently, the stem sorting device generally utilizes the air separation principle to separate tobacco shreds from tobacco stems, the stem separation is completed in a sorting channel, when the tobacco shreds to be sorted enter the sorting channel, air flow is blown from bottom to top, lighter tobacco shreds are blown upwards under the action of wind power to enter a vertical air channel to be collected, and heavier tobacco stems fall downwards out of the sorting channel under the action of gravity to enter a special stem sucking pipeline. In actual operation, because of the limitation of the structural design of the stem sorting device in the prior art, when the existing stem sorting device rejects the tobacco stems in the tobacco shreds, the stem shreds to be sorted are conveyed into the sorting channel from the bottom inlet area, and then the tobacco in the sorting channel is pulled open uncontrollably due to the air flow characteristic in the sorting channel, so that the distribution of the stem shreds in the width direction in the sorting channel is extremely uneven, the tobacco shreds output from the top of the sorting channel are also uneven in the width direction, the tobacco shreds cannot meet the feeding requirement of a follow-up cigarette making machine, and the production speed of the cigarettes is seriously influenced.
