Description

Technical Field

[0001] The present invention relates to the technical field of cigarette equipment, and more specifically, to a quantitative feeding control method, system, electronic equipment and storage medium. Background Art

[0002] In the tobacco-making workshop of a cigarette factory, the quantitative feeding system consists of a cabinet feeder, a discharging vibration trough, a conveyor belt conveyor, a metering tube, and a control electronic scale. The quantitative feeding system is usually set before a certain process to provide a stable flow of tobacco leaves for this process. Figure 4 As shown in the figure, in the quantitative feeding system, the cabinet feeder connects the middle link of the front and rear processes and plays the role of temporary storage of materials. The cabinet feeder reduces the coupling degree of the front and rear processes, and the front process will not be shut down due to temporary failure of the back process; the discharge vibration trough and belt conveyor play the role of material transportation; the metering tube plays the role of material buffer and controlling the start and stop of the quantitative feeding system; the control electronic scale plays the role of material flow control and metering.

[0003] In the traditional control method, the out-of-box speed of the cabinet feeder of the quantitative feeding system is set by the operator according to his own experience, which frequently causes problems such as material blockage or flow rate failing to reach the set value, seriously affecting the quality of silk production. The present invention establishes an automatic flow control model for the quantitative feeding system, realizes that the system automatically adjusts the out-of-box speed according to the material level of the metering tube based on the operating speed of the electronic scale.

[0004] Technical solutions of the prior art

[0005] The operator sets the discharging speed of the cabinet feeder of the quantitative feeding system based on his own experience.

[0006] Disadvantages of existing technology

[0007] 1. Problems in control mode

[0008] When the cabinet feeder's discharge speed is set too high, the cabinet feeder's bottom belt, discharge trough, and belt conveyor will start and stop frequently, causing great damage to the discharge trough. The rocker arm shock absorber of the discharge trough will age prematurely, increasing maintenance costs. When the cabinet feeder's discharge speed is set too low, the flow rate cannot reach the set value, which may cause important indicators such as moisture, feeding accuracy, and fragrance adding accuracy to fail to meet standards, greatly affecting the silk processing quality.

[0009] (II) Problems in production

[0010] The operator cannot adjust the outfeed speed in real time, which is prone to blockage. Taking the one-time feeding process in the workshop as an example, the frequency of blockage in the metering pipes of the one-time feeding of Line A and Line B is relatively high, reaching about 4 times a month. The blockage needs to be manually unblocked, and each blockage takes 10-15 minutes. The unblocking is difficult and requires high-altitude operations, which poses certain safety hazards. After the blockage, the feeder will stop and the feed will be cut off, which will have an adverse effect on the feeding quality. In addition, when the outfeed speed is set unreasonably, the accuracy of the electronic scale will be greatly reduced due to the instability of the material.

[0011] Therefore, how to provide a quantitative feeding control method, system, electronic device and storage medium has become a technical problem that urgently needs to be solved in this field. Summary of the invention
