Leaf moistening control method, storage medium, detection device and leaf moistening system

Abstract

The invention discloses a leaf moistening method of a leaf moistening machine, a detection device, a leaf moistening system and a PLC controller. The leaf moistening control method mainly includes the following steps: Step S1. The incoming material belt transports the material to the leaf moistening machine; Step S2. The ultrasonic sensor above the incoming material belt detects the incoming material; Step S3. The material is transported in place, and the ultrasonic sensor detects the incoming material , the PLC controller opens the water, steam, and gas valves to add steam and water; step S4. After the material is conveyed, the ultrasonic sensor does not detect the incoming material, and the PLC controller closes the water, steam, and gas valves. Beneficial effects: the calculated production flow rate is more accurate through the correction coefficient, and the leaf moistening quality is more stable in the automatic control mode; compared with the electronic metering scale, the device has a simple structure, saves equipment space, and reduces equipment failures rate; compared with electronic metering scales, the input cost is low, and the later maintenance cost is also relatively low.

Description

technical field [0001] The invention belongs to the field of rebaking of tobacco leaves, and relates to a tobacco leaf material detection device, in particular to a leaf moistening control method of a leaf moistening machine, a storage medium, a detection device and a leaf moistening system. Background technique [0002] In the rebaking production, the tobacco leaves need to go through the hot air moistening process before they can enter the leaf threshing and air separation process, then enter the leaf rebaking process, and finally enter the boxing and packaging process. The quality of leaf moistening in the hot air moistening process directly affects the quality indicators of the subsequent process. Therefore, the hot air moistening process plays a key role in the rebaking production process. [0003] Tobacco leaves generally need to be moistened with hot air twice in the pretreatment stage. The hot air leaf moistening machine performs corresponding actions such as adding ...

AI Technical Summary

Problems solved by technology

[0004] This kind of process method belongs to the extensive management method, and there are two problems in the process of moistening leaves. On the one hand, due to the positive correlation between the detection distance and penetration of the photoelectric cell, occasionally there will be failures that cannot accurately detect the material Phenomena, resulting in a poor quality of leaf moistening; on the other hand, because the electronic flow scale is not installed, the discharge flow rate cannot be accurately calculated, and the amount of steam and water added during the leaf moistening process is inaccurate.
