Description

Technical Field

[0001] This document relates to the field of automatic cleaning technology for threshed and re-dried tobacco leaves, and in particular to a method and system for cleaning tobacco leaves based on automatic unloading. Background Technology

[0002] During the tobacco leaf re-drying process, various production line issues may cause downtime. If the downtime exceeds 30 minutes, and the tobacco leaves are not removed from the hot air leaf-drying machine in time, the leaves will remain in a high-temperature and high-humidity environment for an extended period, resulting in substandard tobacco leaves such as damp red tobacco and water-stained tobacco. This not only seriously affects product quality but also causes a significant waste of tobacco leaves.

[0003] Currently, in situations where the hot air leaf humidifier in a tobacco re-drying production line has to be shut down for extended periods, manual cleaning of the tobacco leaves is typically used to remove them from the machine. Manual cleaning requires that the temperature of the hot air leaf humidifier drop to a safe range before workers enter the machine to remove the leaves one by one. The specific process is as follows: workers enter the machine via a ladder from the discharge end and manually carry the tobacco leaves out of the machine, starting from the nearest point and working their way out. Outside the machine, workers collect and organize the scattered leaves into prepared tobacco crates. The filled crates are then transported to a designated location by transfer personnel, ready for return processing.

[0004] The manual cleaning method for tobacco leaves has several drawbacks: 1. Manually removing tobacco leaves requires workers to enter the hot air humidifier. The hot air humidifier has a high temperature and harsh environment, and is densely packed with rakes, posing a risk of injury such as bumps, trips, and burns to workers. 2. In the event of a sudden production interruption, the internal temperature of the hot air humidifier is approximately 70-80℃. Manually cleaning these tobacco leaves requires waiting for the temperature inside the humidifier to drop below 40℃ before multiple workers can enter the equipment, which is time-consuming and labor-intensive. 3. During manual work inside a hot air humidifier filled with tobacco leaves, there is a risk of trampling the leaves, causing them to break and resulting in unnecessary economic losses. Summary of the Invention

[0005] This specification provides one or more embodiments of a method for cleaning tobacco leaves based on automatic unloading, including:

[0006] The material discharge start-up criteria are used to determine whether the production line has met the material discharge start-up conditions.

[0007] Once the material unloading start conditions are confirmed, the hot air leaf humidifier will automatically unload the material through a preset combination control program.

[0008] According to the combined control program, the operation of the hot air leaf humidifier is controlled to transport the tobacco leaves inside the hot air leaf humidifier to the ground.

[0009] Once the tobacco leaf conveying in the hot air leaf humidifier is completed, the unloading process is stopped.

[0010] This specification provides one or more embodiments of an automatic unloading tobacco leaf cleaning system, including:

[0011] Material discharge start confirmation module: Used to determine whether the production line has met the material discharge start conditions based on the material discharge start conditions;

[0012] Material discharge start module: After confirming that the material discharge start conditions have been met, the hot air leaf humidifier will start automatically to discharge materials through a preset combination control program;

[0013] Material unloading operation module: used to control the operation of the hot air leaf humidifier according to the combined control program, and to transport the tobacco leaves inside the hot air leaf humidifier to the ground;

[0014] Material discharge stop module: Used to stop material discharge when the feeding of tobacco leaves in the hot air leaf humidifier is completed.

[0015] This invention also provides a tobacco leaf cleaning device based on automatic unloading, comprising: a memory, a processor, and a computer program stored in the memory and executable on the processor. When the computer program is executed by the processor, it implements the steps of the above-described tobacco leaf cleaning method based on automatic unloading.

[0016] This invention also provides a computer-readable storage medium storing an information transmission implementation program, which, when executed by a processor, implements the steps of the above-described tobacco leaf cleaning method based on automatic unloading.

[0017] The present invention addresses the problems of long processing time, low efficiency, large leaf breakage, and numerous safety hazards associated with current manual leaf removal methods. By developing a control program, existing production line equipment is used to transport tobacco leaves from the hot air humidifier, eliminating the need for additional machinery and reducing costs. Utilizing existing equipment for leaf transport eliminates the need to wait for the hot air humidifier to cool down, resulting in a rapid process that improves cleaning efficiency and reduces time costs. The equipment's operation avoids requiring personnel to enter the enclosed hot air humidifier, mitigating risks of falls and burns. Furthermore, the absence of personnel inside the humidifier prevents economic losses caused by trampling on tobacco leaves.
