Discharge adjusting device of tobacco primary processing and mixing cabinet and discharging device

Abstract

The invention relates to the technical field of tobacco production equipment, and provides a discharging adjusting device of a tobacco primary processing and mixing cabinet and a discharging device. The adjusting device comprises a first PID controller, a second PID controller, a downstream processing device set flow acquiring device, a downstream processing device actual flow acquiring device, atobacco shred mixing cabinet theoretical discharging flow acquiring device and a metering pipe; the downstream processing device set flow acquiring device and a tobacco shred mixing cabinet theoretical discharging flow acquiring device are connected with the two input ends of the first PID controller respectively, the output end of the first PID controller is connected with a bottom belt on a tobacco shred mixing cabinet, and the first PID controller can control the speed of the bottom belt; and the metering pipe and the downstream processing device actual flow acquiring device are connected with the two input ends of the second PID controller respectively, the output end of the second PID controller is connected with the bottom belt, and the second PID controller can control the speed ofthe bottom belt. Compared with the prior art, the adjusting device has the beneficial effect that the overall discharging flow is more uniform and stable.

Description

technical field [0001] The invention relates to the technical field of tobacco production equipment, in particular to a discharge regulating device of a tobacco shred mixing cabinet and a discharge device. Background technique [0002] At present, the output adjustment of the silk mixing cabinet in the silk workshop is usually carried out in two ways. [0003] The first method is: the discharge adjustment of the silk mixing cabinet in the silk workshop is controlled by the high and low material level photocells of the metering tube behind the electronic belt scale. Stop the unloading of the silk mixing cabinet. When the metering tube has a low material level photoelectric switch and there is no signal, the unloading starts. The bottom belt of the silk mixing cabinet usually adopts a speed to control the unloading. [0004] Another method is to adjust the output of the silk mixing cabinet in the silk workshop by using a grating to control the metering tube behind the electro...

AI Technical Summary

Problems solved by technology

[0005] However, there are obvious shortcomings in the above two existing technologies: the shortcoming is reflected in that the above-mentioned discharge adjustment method does not take into account the uneven distribution of shredded tobacco in the silk mixing cabinet

[0007] 1. The flow of shredded tobacco coming out of the blending cabinet is easily affected by the unevenness of the cloth, which may easily cause the production line to be blocked and the supply of raw materials to be insufficient during the production process, which will affect the uniform flavoring of shredded tobacco;

[0008] 2. If the high and low material level photocells of the metering tube are used to control the start and stop of the belt conveyor, vibrating conveyor, bottom belt of the silk mixing cabinet, and rake motor, frequent start and stop during the production process will easily cause mechanical parts and electrical Parts are damaged, causing the production process to stop, cut off materials and consume parts

[0009] 3. The set flow rate of the electronic belt scale cannot be adjusted too large, otherwise it will affect the continuity of production

Therefore, it is impossible to set the flow rate through the electronic belt scale to adapt to the fluctuation of the flow rate of the upstream mixing cabinet

[0010] 4. Operators are required to manually adjust the speed of the bottom belt of the mixed silk cabinet at any time
