Problems solved by technology

Tobacco leaf softness is mostly measured by the softness of fiber, leather, paper and other materials that need to be tested for softness, and the softness of "deflection", "resonance frequency" and "equal bending pressure" is often used to detect its softness. It is more troublesome to detect and calculate
However, cut tobacco has different lengths and widths, and a single cut tobacco is small in size, and it is difficult to make a representative standard single cut tobacco, which is not suitable for the existing softness detection of tobacco leaves.

Embodiment Construction

[0030] like figure 1 As shown, the present invention includes a method for detecting softness of shredded tobacco, comprising the following steps:

[0031] Step 1: Turn on the power supply of the shredded tobacco softness detector, calibrate and zero; on the pressing mechanism of the shredded tobacco softness detector, an extruding plate 6 is vertically arranged;

[0032] Step 2: Set the parameters of the shredded tobacco softness detector: set the pressing time of the shredded tobacco pressing mechanism as T, the pressing pressure as F, and the initial height of the shredded tobacco sample at the initial moment as H 0 ;

[0033] Step 3: Weigh the sample shredded tobacco, and place the sample shredded tobacco in the measuring cylinder 7 matching the shape of the extrusion plate 6 in a natural accumulation method, and flatten the upper end surface of the sample shredded tobacco until the height of the sample shredded tobacco in the measuring cylinder 7 is initial height H 0 ...

Abstract

The invention discloses a method for measuring the softness of cut tobacco. The initial height of a cut tobacco sample is set to be constant according to the different softness of the cut tobacco anddifferent deformation under stress, through an extrusion plate, the cut tobacco in a measuring cylinder is extruded downwards for the pressing time T at the constant pressing pressure F, the extrudedheight H1 of the cut tobacco with the different softness directly facing the extrusion plate varies, the ratio of a height difference between the extruded height H1 and the initial height H0 to the initial height H0 is used for characterizing the softness S of the cut tobacco sample, and the softness of the cut tobacco is reflected more accurately and truly. A cut tobacco softness detector comprises a base, a machine body, an extruding plate, a measuring cylinder, a cut tobacco pressing mechanism, a cut tobacco height measuring mechanism and a detector control system, the cut tobacco pressingmechanism comprises a sliding shaft and a driving mechanism for driving the sliding shaft to move up and down, the extrusion plate and the lower end face of the sliding shaft are vertically and fixedly arranged, and a counterweight weight is arranged on the upper end face of the sliding shaft, so as to extrude the cut tobacco softness detector.

Description

technical field [0001] The invention relates to the technical field of tobacco physical quality detection, in particular to a method for detecting the softness of shredded tobacco and an instrument for detecting the softness 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. , Excluding the large amount of shorts, it is not easy to use; at the same time, we found that these "easy-to-use" shredded tobacc...
