Problems solved by technology

Using this method to adjust the frequency, due to the limitation of human operation experience and the lag of offline detection index results, the adjustment basis of the leaf threshing equipment is unreliable, resulting in frequent adjustment of the leaf threshing equipment, resulting in large fluctuations in the index of the stem content rate in the tobacco leaves, and it takes a long time. Time can stabilize product quality

Embodiment Construction

[0020] The present invention will be described in detail below in conjunction with specific embodiments.

[0021] The invention provides a method for adjusting the frequency of leaf-threshing equipment, comprising the following steps:

[0022] S1: In the threshing section of the threshing and redrying production line, determine the threshing adjustment control point according to the layout of the production equipment, and divide each adjustment control point into 4 levels of threshing process, which are: 1st level threshing process, 2nd level Leaf threshing process, 3-level threshing process, 4-level threshing process; determine the number of air separators corresponding to each level of threshing process;

[0023] S2: According to the defoliating process, calculate the sum SQ of the air split flow rate of the j-th stage defoliating process j : Among them, g is the sampling weight (unit is kg); t is the opening time of the flap door set manually (unit is second). Switching...

Abstract

The invention belongs to the technical field of tobacco leaf threshing in crude tobacco production, and particularly relates to a method for adjusting the frequency of threshing equipment. How to adjust the frequency of the threshing equipment in the corresponding process is judged by comparing the deviation between a target threshing rate and an actual threshing rate with a normal deviation valueand comparing a theoretical fragment rate with an actual fragment rate. According to the method, dynamic calculation of the air distribution flow is realized, and the set frequency of the threshing equipment can be quickly and accurately adjusted.

Description

technical field [0001] The invention belongs to the technical field of leaf threshing in raw tobacco production, and in particular relates to a method for adjusting the frequency of leaf threshing equipment. Background technique [0002] The proportion of stalks in the tobacco leaves is an important assessment index for the finished tobacco after threshing and rebaking, and the effect of threshing is an important factor that directly affects the index of stalks in the leaves. At present, in the field of threshing and redrying technology, the control of the stalk content rate in tobacco leaves is generally obtained by sampling and off-line detection to obtain the result of the stalk content rate in the actual tobacco leaves. According to the comparison results, the equipment operator adjusts the setting frequency of the leaf-threshing equipment in combination with his own experience in adjusting and controlling the leaf-threshing equipment. Using this method to adjust the fr...
