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 with reference to specific embodiments.

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

[0022] S1: In the threshing section of the threshing and redrying production line, according to the layout of the production equipment, determine the threshing adjustment control points, and divide each adjustment control point into 4 levels of threshing processes, namely: 1-level threshing process, 2-level threshing process Defoliation process, 3-level defoliation process, 4-level defoliation process; determine the number of air separators corresponding to each level of defoliation process;

[0023] S2: According to the threshing process, calculate the sum SQ of the air flow in the j-th threshing process j : Among them, g is the sampling weight (unit is kg); t is the manually set opening time of the flap door (unit is seconds). Switch equipment, ...

Abstract

The invention belongs to the technical field of tobacco threshing in the production of raw tobacco, and particularly relates to a method for adjusting the frequency of threshing equipment. By comparing the deviation between the target chip rate and the actual chip rate and the normal deviation value, and the theoretical fragment rate and the actual fragment rate, it can be judged how to adjust the frequency of the threshing equipment for the corresponding process. The invention realizes the dynamic calculation of the air distribution flow, and can quickly and accurately adjust the set frequency of the threshing equipment.

Description

technical field [0001] The invention belongs to the technical field of tobacco threshing in raw tobacco production, and particularly relates to a method for adjusting the frequency of threshing equipment. Background technique [0002] The proportion of stalks in tobacco leaves is an important evaluation index for the finished tobacco after threshing and redrying. The effect of threshing is an important factor that directly affects the index of stalk content in leaves. At present, in the technical field of threshing and redrying, the control of the stalk content rate in tobacco leaves is generally obtained through sampling and offline detection to obtain the stalk content rate results in the actual tobacco leaves. The equipment operator adjusts the set frequency of the threshing equipment according to the comparison results and his own experience in adjusting and controlling the threshing equipment. Using this method to adjust the frequency is limited by human operation expe...
