Stem end tobacco, tobacco winder and non-tobacco related material separation method

Abstract

The invention discloses a stem end tobacco, tobacco winder and non-tobacco related material separation method relating to a tobacco leaf processing technology. The stem end tobacco, tobacco winder and non-tobacco related material separation method is characterized by being realized through the following technical scheme: a. conveying a split end tobacco to a tobacco end scattering machine; b. sectionally arranging three groups of abrasive disc type belt conveyers with different heights and certain friction on the upper part of the tobacco end scattering machine proposed in the step a, and carrying out rubbing, spreading and roller-to-roller conveying on the split end tobacco through the abrasive disc type belt conveyers so that a tobacco winder and a stem end tobacco are sufficiently scattered; c. feeding the scattered material in the step b into a vibration separator, separating the tobacco winder, the stem end tobacco and tiny gravel from powder through vibration conveying, and outputting from an upper path, a middle path and a lower path; d. feeding a small part of smashed tobacco flake and tobacco winder remained in the stem end tobacco in the separation process in the step c into a gravity suspension separator and separating the smashed tobacco flake, the tobacco winder and non-tobacco related material remained in the gravity suspension separator through gravity suspension separation. The stem end tobacco, tobacco winder and non-tobacco related material separation method is characterized in artful combination of principles such as an abrasive disc principle, a vibration principle, a suspension separation principle and the like so that objects with different shapes are effectively separated under the condition that the material is not impacted by a strong external force in the material transferring process. A sufficient condition is created for subsequent reprocessing.

Description

technical field [0001] The invention relates to a tobacco leaf processing technology, in particular to a method for separating stem tobacco, tobacco coils and non-tobacco impurities. Background technique [0002] Tobacco leaf unbundling is an important link before threshing and redrying. After untying and spreading the bundled tobacco leaves, they can be heated and humidified, so as to meet the requirements of the threshing process and reduce the damage of tobacco leaves. Rate. As far as untying is concerned, at present, there are mainly two methods of manual untying and mechanical untying at home and abroad. Manual untying is labor-intensive and time-consuming, and the work efficiency is extremely low, which is no longer suitable for the requirements of industrialized continuous production. Although the mechanical handle solves the labor-intensive and low-efficiency problems of manual handle removal, it cannot remove defective cigarettes and non-smoke inclusions bundled in...

AI Technical Summary

Problems solved by technology

[0003] The purpose of the present invention is to overcome the problems of the low rate of loose handles in the existing mechanical debonding and redrying process, and the inability to effectively separate the stem tobacco, tobacco coils, and non-tobacco impurities, which affect the processing quality of the original tobacco, and the like. Provides a method for separating stem tobacco, tobacco wrap, and non-smoke debris with a high rate of scatter and can effectively share stem tobacco, tobacco wrap, and non-smoke debris
