Problems solved by technology

However, the metering tube of the existing technology is vertically installed, and there is a certain height difference. When the shredded tobacco is humidified by a warming and humidifying machine, its moisture content is usually 26%, and the moisture content is relatively high. Tobacco agglomeration often occurs, which makes the tobacco on the belt of the electronic scale uneven, and the flow fluctuates greatly, which makes the subsequent processing more difficult.
Therefore, it is difficult to use the traditional metering tube to control the material flow to meet the balance requirements in actual production, and it can no longer meet the requirements of modern fine processing technology for the flow control of large-moisture shredded tobacco

Embodiment Construction

[0013] 1. In traditional electronic scales and warehouse-type feeder devices, metering tubes and shifting roller mechanisms are usually used to sort out and control the flow of shredded tobacco. Because the moisture content of the shredded tobacco material is relatively high, the shredded tobacco often agglomerates due to its own weight extrusion when passing through the metering pipe. The process adjusts the length, distribution density, and relative position of the rake nails on the material roller, and the relative position between the material roller and the belt. After testing, it is finally determined that the length of the rake nails is 10 cm, and 8 rows are evenly distributed along the circumference of the material roller. A row of 19 evenly distributed rakes strengthens the combing effect of the feed roller on the shredded tobacco, and can well control the thickness and uniformity of the shredded tobacco on the belt; The distance is 8 mm, so as to ensure that the freq...

Abstract

The invention discloses a material flow control method, particularly relates to a method for controlling material flow balance without a quantitative feed pipe, and belongs to the field of material flow control. The method is applied in computer programming technology, electronic gear box technology and frequency converter control technology, and improves the conventional material flow process in the following modes: removing a quantitative pipe device; redesigning a material dialing roller device, and adjusting the position of a material dialing roller; changing the control mode, and taking a hoister belt as an electric control point; determining a speed controller mode; and establishing a data communication mode between an electronic balance and a hoister PLC. The method applied in a process of controlling cigarette manufacturing shreds can balance the flow of high-moisture tobacco shreds, improve the conveying precision of the material, reduce the conveying fluctuation of the material, facilitate the processing of subsequent processes of the tobacco shreds, improve the quality of cigarettes and relieve the labor intensity of operators at the same time, and has good industrial application value and popularization and application prospects.

Description

technical field [0001] The invention belongs to the field of material flow control, and relates to a method for controlling the balance of material flow, in particular to a method for controlling the balance of material flow without a quantitative feeding pipe. Background technique [0002] At present, electronic scales are commonly used in the flow control of tobacco silk production lines, and quantitative tubes are installed at the entrance, and the fluctuation of feeding is adjusted by high and low material levels: when the material is higher than the high material level, the feeding is stopped; when the material is lower than the low material level, the feeding is accelerated; Between the high and low material levels, the material is fed normally; and the PID is used to adjust the belt speed of the electronic scale, so as to accurately control the material flow. Lay a good foundation for the stability of subsequent processing. However, the metering tube of the existing ...
