Cut tobacco support strength detection method and detector

Abstract

The invention discloses a cut tobacco support strength detection method. Sample cut tobaccos in a measuring cylinder are pressed once by flattening the pressure, then the cut tobaccos in the measuringcylinder are pressed down for a certain period of time by applying the pressure, after the cut tobaccos with different support strength are pressed, the height variation is different, the support strength Q of the sample cut tobaccos is characterized by the ratio of the first compression height H0 to the height difference between the first compression height H0 and the second compression height H1, the overall support strength of the sample cut tobaccos is characterized, and thus the support strength of the cut tobaccos is reflected more accurately and truly. The invention discloses a cut tobacco support strength detector. The cut tobacco support strength detector comprises a base, a machine body, the measuring cylinder, a cut tobacco pressing mechanism, a cut tobacco height measuring mechanism and a detector control system; the cut tobacco pressing mechanism comprises a pressing head, a sliding shaft and a driving mechanism; the pressing head is connected to the lower end surface ofthe sliding shaft, under the control of the detector control system, the driving mechanism drives the sliding shaft to move up and down, and the support strength of the cut tobaccos is measured accurately.

Description

technical field [0001] The invention relates to the technical field of tobacco physical quality detection, in particular to a method for detecting the support strength of shredded tobacco and a detector for the support strength of shredded tobacco. Background technique [0002] At present, the current indicators for evaluating the physical quality of shredded tobacco mainly include moisture content, filling value, and structure. Through the evaluation of these indicators, the processing and production of cigarettes are well guided. However, in the actual production process, we found that some batches of shredded tobacco with roughly the same physical indicators have a low shutdown rate during the rolling process, and the number of shorts removed is small, which is very useful; while other batches have a high shutdown rate during the rolling process. , It is not easy to use because of the large amount of empty space; at the same time, during the transportation of cigarettes, ...

Problems solved by technology

However, in the actual production process, we found that some batches of shredded tobacco with roughly the same physical indicators have a low shutdown rate during the rolling process, and the number of shorts removed is small, which is very useful; while other batches have a high shutdown rate during the rolling process. , it is not easy to use because of the large amount of empty space; at the same time, during the transportation of cigarettes, some cigarettes are easy to be deformed by force, while some cigarettes are stable in shape, because the supporting strength of shredded tobacco is different

In the tobacco industry, there is only a method for testing the softness of tobacco leaves, and it is not comprehensive enough to use the softness of tobacco leaves to evaluate the support strength of shredded tobacco

First of all, the test methods for the support strength of tobacco leaves are mostly used to measure the support strength of materials such as fiber, leather and paper that need to be tested for support strength, and the methods such as "deflection", "resonance frequency" and "equal bending pressure" are often used to test the support strength. , detection and calculation are cumbersome, and the elasticity of tobacco leaves does not represent the softness of shredded tobacco, but shredded tobacco has different lengths and widths, and the volume of a single shredded tobacco is small, and it is difficult to make a representative standard single shredded tobacco. The softness of shredded tobacco Second, the softness of shredded tobacco refers to the ability of shredded tobacco to be deformed, and the relationship between the shortness and easy deformation of shredded tobacco is more closely related to the support strength of shredded tobacco
