Cut tobacco elasticity on-line detection device and method thereof

Abstract

The invention discloses a cut tobacco elasticity on-line detection device and a method thereof. The on-line detection device comprises an installation bracket, at least two cut tobacco thickness-measuring devices, a conveyer belt and a data acquisition and processing system. The cut tobacco thickness-measuring devices comprise a first cut tobacco thickness-measuring device and a second cut tobacco thickness-measuring device arranged above the conveyer belt. The first cut tobacco thickness-measuring device and the second cut tobacco thickness-measuring device are sequentially arranged at the installation bracket with a set interval along the moving direction of the conveyer belt. The central lines of the first cut tobacco thickness-measuring device and the second cut tobacco thickness-measuring device are consistent with the moving direction of the conveyer belt and are parallel with each other. The data acquisition and processing system is connected with the first cut tobacco thickness-measuring device and the second cut tobacco thickness-measuring device and is used for acquiring a first signal and a second signal which are obtained by measuring the thickness of cut tobacco respectively by the first cut tobacco thickness-measuring device and the second cut tobacco thickness-measuring device when the cut tobacco is conveyed on the conveyer belt, and the data acquisition and processing system is also used for obtaining the elasticity value of the cut tobacco according to the first signal and the second signal. The invention can realize on-line detection of the elasticity of the cut tobacco.

Description

Technical field [0001] The invention relates to a tobacco processing detection equipment, in particular to an online detection device and a method for measuring the elasticity of the cut tobacco during the production process of the cut tobacco. Background technique [0002] Tobacco elasticity refers to the ability to recover after a certain pressure is applied to the cut tobacco within a certain period of time after the pressure is released. The elasticity of cut tobacco is one of the important factors affecting the quality of cigarettes. When the elasticity of cut tobacco is large, the amount of cut tobacco used in rolling cigarettes is small, the air permeability is good when the cigarette is burned, the content of tar, nicotine and carbon monoxide in the smoke is also small, and the taste is good. When the elasticity of shredded tobacco is small, the amount of shredded tobacco used in rolling cigarettes is large, the air permeability of the cigarette is not good when the cigar...

AI Technical Summary

Problems solved by technology

[0010] The above-mentioned random sampling off-line static measurement method is far from being able to accurately reflect the tobacco elasticity value and its changes during the entire production process of cut tobacco in a timely manner, and cannot meet the production needs. The online detection device for cut tobacco elasticity is still blank at present.
