Problems solved by technology
The tensile performance of shredded tobacco is an important factor to evaluate the processing performance of shredded tobacco. The current detection of the tensile performance of shredded tobacco mainly adopts manual stretching, which has the disadvantages of low accuracy and low work efficiency through the subjective feeling of the ability of shredded tobacco to withstand external forces.

Abstract
The invention discloses a method for testing the tensile properties of cut tobacco. The method comprises the following steps of: clamping both ends of the cut tobacco and placing the cut tobacco in abent state; fixing one end of the cut tobacco, and applying tensile force away from the fixed end of the cut tobacco to the moving end of the cut tobacco until the tobacco is completely straightened;continuing to apply the tensile force to the fully straightened cut tobacco until the cut tobacco is broken, obtaining the tensile force F received by the fixed end of the cut tobacco when the cut tobacco is broken, and obtaining the deformation quantity S of the cut tobacco from the complete straightening to the tensile failure; and obtaining the tensile elasticity of the cut tobacco by calculation according to F / S. The method for detecting the tensile properties of the cut tobacco has high degree of accuracy and high working efficiency, and can quickly and accurately detect the tensile properties of the cut tobacco.
Description
technical field [0001] The invention relates to the field of performance detection of shredded tobacco, in particular to a method for detecting the tensile performance of shredded tobacco. Background technique [0002] Shredded tobacco is formed after cutting tobacco leaves and is used as a raw material for the production of cigarettes. At present, cigarette industry enterprises mainly focus on the performance parameters of shredded tobacco, such as tobacco filling value, elasticity, whole shred rate and moisture content. The values of these performance parameters will directly affect the sensory quality of cigarettes and the amount of smoke released. However, the existing performance parameters of shredded tobacco cannot fully reflect the processing performance of shredded tobacco. During the rolling process of cigarettes, it was found that the tensile properties of shredded tobacco had an important influence on the applicability of the machine. [0003] Taking the tens...
