Embodiment Construction

[0019] In the process of realizing the present invention, the inventors found that in the process of making tobacco shreds, the feeding accuracy and moisture accuracy are usually important indicators for process quality assessment. In the current technology, the control of the feeding machine mainly focuses on the feeding accuracy. Usually The feeding accuracy is required to reach ±0.5%. The feeding machine generally has an independent feeding control system, and the PID loop control technology is used to adjust the feeding flow to control the feeding accuracy. As for the control of the moisture at the outlet of the feeder, some main equipment adopts the method of steam supplementation or water injection to adjust the outlet moisture. Most of them adopt the open-loop control method, and the control accuracy is low. Therefore, the process of the silk production line is usually not strict with this index. assessment. But in fact, with the development of the process in recent ye...

Abstract

The embodiment of the invention provides a control system and method for manufacturing tobacco. The method comprises a detecting device arranged at a feeding hole and the discharging hole, an actuatorand a controller. The detecting device is used for collecting feeding data of the feeding hole and discharging data of the discharging hole and sending the feeding data and the discharging data to the controller. The controller is configured to operate a closed-loop control signal according to the feeding data and the discharging data and send the closed-loop control signal to the actuator. The actuator is used for controlling a feeding flow and a water adding flow of the feeding hole based on the closed-loop control signal. Therefore, the influence on the material moisture by the disturbanceamount in the feeding process is considered; and with closed-loop controlling, the control precision of the material and water feeding is improved.

Description

technical field [0001] The invention relates to the technical field of tobacco shredded control, in particular to a control system and method for tobacco production. Background technique [0002] In the tobacco shredded process, the feeding accuracy and moisture accuracy are usually important indicators for process quality assessment. The main function of the feeding link is to add spices to tobacco materials such as leaves, shredded leaves, and shredded stems, thereby improving the final cigarette product. quality. The feeding process is realized by the feeding machine, whose main function is to spray the material passing through the feeding drum according to the feeding ratio required by the process, and to adjust the moisture of the material by steam injection or water injection while the material is loose, so that The processed materials meet the process requirements. [0003] In the current technology, the control of the feeder mainly focuses on the feeding accuracy, ...
