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. At the same time, we found that these "easy-to-use" shredded tobacco tends to be more elastic, while these "unusable" shredded tobacco is often stiff and inelastic. How to detect the elasticity of shredded tobacco? Tobacco industry standard "YC/T186-2004 ...

Embodiment 1

[0032] Such as figure 1 As shown, the present invention includes a method for detecting elasticity of shredded tobacco, comprising the following steps:

[0033] Step 1: Turn on the power of the shredded tobacco elasticity detector, calibrate and zero;

[0034] Step 2: Set the parameters of the shredded tobacco elasticity detector: set the pressing time of the shredded tobacco pressing mechanism as T 1 , the pressure height of shredded tobacco at the end of pressure is H 0 , the pressure release time of shredded tobacco after pressure application is T 2 ;

[0035] Step 3: Weigh the sample shredded tobacco with a mass of M, place the sample shredded tobacco in the measuring cylinder 7, and place the measuring cylinder 7 at the measuring position;

[0036] Step 4: Carry out shredded tobacco pressing and obtain test parameters: the detector control system controls the shredded tobacco pressing mechanism to move down at a constant speed T 1 time, the cut tobacco pressing mecha...

Embodiment 2

[0061] Such as Figure 5 As shown, in the described shredded tobacco elasticity detector, the shredded tobacco height measuring mechanism also includes a sensor mounting ring 10 fixedly sleeved on the sliding shaft 5; the lower wall of the sensor mounting ring 10 is fixedly provided with a plurality of ranging sensors 11, so The distance measuring sensors 11 are evenly arranged along the circumference of the installation ring; the pressing head 6 is provided with signal through holes 12 corresponding to the distance measuring sensors 11 one by one, and each signal through hole 12 is inlaid with a transparent plate, The lower end face of the transparent plate is flush with the lower end face of the pressing head 6 . The transparent plate can be made of glass fiber reinforced plastic.

[0062] During the process of pressing shredded tobacco by pressing head 6, friction will inevitably occur. Due to electrostatic adsorption, sometimes the lower end surface of pressing head 6 wil...

Abstract

The invention discloses a tobacco shred elasticity detection method. According to the method, the initial position of a tobacco shred pressing mechanism is constant, the moving distance in the pressing process is constant, the pressure height H<0> of tobacco shreds at a pressure application ending moment is constant, height L<0> covers tobacco shred filling values, tobacco shred elasticity obtained through calculation conceals defects of part of elasticity values, and the tobacco shred elasticity is reflected more accurately and truthfully. A tobacco shred elasticity detector comprises a base,a body, a measuring cylinder, the tobacco shred pressing mechanism, a tobacco shred height measuring mechanism and a detector control system, wherein the tobacco shred pressing mechanism comprises apressing head matched with the measuring cylinder, a sliding shaft and a driving mechanism, weights are arranged on the upper end face of the sliding shaft, and the driving mechanism drives the sliding shaft to move up and down at a constant speed; and the pressure of the tobacco shred pressing mechanism in the sample tobacco shred pressing process is adjusted through the weights, more comprehensive evaluation of tobacco shred quality is benefited, and technical support is provided for quality improvement and evaluation work of the tobacco shreds.

Description

technical field [0001] The invention relates to the technical field of tobacco physical quality detection, in particular to a method for detecting elasticity of shredded tobacco and an instrument for detecting elasticity 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. At the same time, we found that these "easy-to-use" shredded tobacco tends to be more elastic, while these "unusable" shredded tobacco...
