Early warning control system for material moisture exceeding the limit of drum silk drying machine

Abstract

The invention discloses a material moisture limit-exceeding early warning and control system of a roller cut-tobacco drier. On the basis that the control functions of the original roller cut-tobacco drier are not changed, real-time data collected by an infrared moisture tester at an outlet of the cut-tobacco drier is adopted for controlling the operation of the cut-tobacco drier, namely, when thematerial moisture of the cut-tobacco drier is within the process index range, only regulation control is involved, but the operation control is not involved. When the material moisture of the cut-tobacco drier exceeds an upper limit value of the process index, the prompt information that 'the material moisture of the cut-tobacco drier exceeds the limit'is provided on an upper operation interface in time, when the information occurs continuously, a cut-tobacco drying section has failure warning, equipment at the cut-tobacco drying section stops operation automatically, a belt motor at the outlet of the cut-tobacco drier operates towards the opposite direction for timely pouring out materials in the cut-tobacco drier, thus the functions of automatic early warning and control for the limit exceeding of the material moisture of the cut-tobacco drier are realized, the unqualified materials are prevented from flowing into a follow-up working procedure, thus the quality of the finished product cut tobacco is guaranteed, meanwhile, the labor intensity of manual monitoring of operators is greatly reduced, and the operation is simple and feasible.

Description

technical field [0001] The invention belongs to the field of electrical control of tobacco machinery, and in particular relates to an early warning control system used in the shred drying process of a cigarette shred workshop. Background technique [0002] The shred drying process is one of the key processes in the production of shredded tobacco in every cigarette factory. Its main technological task is to remove part of the moisture in the shredded tobacco, and to make the shredded tobacco bend to a certain extent, to improve the filling value and processing resistance of the shredded tobacco, and to improve the sensory quality of the shredded tobacco. Meet the requirements of subsequent processing technology. The quality of the control of the drying process plays a vital role in the internal quality of the cut tobacco, and the moisture and stability of the material in the drying machine are the key physical indicators that affect the quality of cigarette rolling.

AI Technical Summary

Problems solved by technology

For example, in the actual production process, when the hot air volume and moisture discharge volume in the first control mode have reached the limit (that is, the adjustment no longer works), the moisture in the material of the silk dryer will exceed the upper limit of the process requirement (the so-called If the operator does not find out in time, these unqualified materials will enter the subsequent process, which will have a great impact on the quality of cigarette products. In severe cases, macular smoke, moldy smoke, etc. will occur. serious quality accident

In addition, even if the operator finds out in time and shuts down the machine, it will bring great inconvenience to the handling of these unqualified materials entering the subsequent process, and at the same time increase the labor intensity of the operator
