Description

Technical Field

[0001] This utility model relates to the field of tobacco processing technology, specifically to automated control equipment for tobacco pretreatment production lines. Background Technology

[0002] Traditional tobacco pretreatment relies heavily on manual feeding, inspection, and humidification. Manual feeding struggles to precisely control the amount and uniformity of material, leading to instability in subsequent processing steps. Manual inspection is inefficient and highly subjective, making it difficult to accurately grasp various parameters of the tobacco leaves. Manual humidification further compromises uniformity and appropriateness, affecting the quality of pretreatment. Furthermore, some existing automated equipment lacks effective coordination between units. For example, the feeding unit cannot dynamically adjust the feeding amount based on the actual condition of the tobacco leaves; the inspection unit cannot promptly and accurately feed data back to other units for coordinated control; and the humidification unit cannot precisely adjust humidification parameters based on the real-time temperature, humidity, and moisture content of the tobacco leaves. In addition, existing equipment control devices are inconvenient to operate, have low levels of intelligence, and weak fault diagnosis and handling capabilities, failing to meet the demands of modern large-scale, high-quality tobacco pretreatment production.

[0003] Therefore, it is necessary to design automated control equipment for tobacco pretreatment production lines to solve the problems mentioned above. Utility Model Content

The tobacco leaves are stored in the tobacco leaf storage cylinder 11. The feeding motor 14 drives the spiral automatic feeder 12 to operate. The spiral blades, designed according to the flowability of the tobacco leaves and the required feeding volume, transport the tobacco leaves from the tobacco leaf storage cylinder 11 to the outlet 13, and then feed the tobacco leaves onto the conveyor belt 5 through the outlet 13. This achieves automated feeding, precise control of the feeding volume and uniformity, ensures stable operation of subsequent processes, reduces manual intervention, and improves feeding efficiency and accuracy.

[0033] Specifically, the tobacco leaf detection unit 2 includes a first fixed frame 21 fixedly installed on the top of the outer shell on both sides of the conveyor belt 5.

Guide grooves 36 are correspondingly opened inside the left and right sides of the second fixed frame 31, and the guide blocks 37 and guide grooves 36 are slidably connected. A water distribution plate is correspondingly installed inside the horizontally movable block 33, and several atomizing spray nozzles are opened below the water distribution plate. The telescopic cylinder 32 has a stroke range of 0-300mm, and its extension speed can be adjusted by a flow control valve to adapt to different humidification process requirements.

The water supply device 7 includes a water storage tank, a water pump, and a water quality filter assembly. The water quality filter assembly adopts a multi-stage filtration structure, which can effectively filter impurities in the water and prevent the atomizing nozzle 34 from clogging. The temperature and humidity sensing probe 38 detects the temperature and humidity data above the conveyor belt 5 in real time and transmits it to the automatic control device 4. The telescopic cylinder 32 adjusts the height of the lateral moving block 33 according to the control command, and the guide block 37 slides in the guide groove 36 to ensure movement stability. The water pump in the water supply device 7 pumps water from the storage tank through multi-stage filtration, then delivers it to the water distribution plate via the water supply pipe 35, and finally sprays it out from the atomizing nozzle 34. According to different humidification process requirements, the extension and retraction speed of the telescopic cylinder 32 is adjusted via the flow control valve, simultaneously adjusting the spray angle and atomized particle size of the atomizing nozzle 34 for humidification operations. This achieves precise and uniform humidification, effectively avoiding insufficient or excessive humidification of tobacco leaves, meeting the humidification process requirements of different tobacco leaves, improving tobacco quality, and the filtration structure of the water supply device ensures the long-term stable use of the atomizing nozzle.

Operators input operating commands and process parameters through the control buttons 42 (start button, stop button, emergency stop button, parameter adjustment button). The display screen 41 displays equipment operating parameters, fault information, and tobacco leaf detection and processing status in real time. The automated control device 4 receives image data from the tobacco leaf detection unit 2 and temperature and humidity data from the tobacco leaf humidification unit 3, analyzes and processes the data, and then sends control commands to each unit to achieve automated operation of the equipment. When equipment malfunctions, it can be repaired through the inspection door 43; this enables intelligent and automated control of the equipment, allowing operators to monitor the equipment's operating status and tobacco processing in real time, promptly detect and handle faults, improve equipment operation convenience and production efficiency, and reduce manual labor intensity and operational error rate.

The feeding motor 14 drives the spiral automatic feeder 12 to operate. According to the tobacco leaf flowability and feeding volume requirements, the spiral blades transport the tobacco leaves from the tobacco storage cylinder 11 to the discharge port 13, and then from the discharge port 13 to the conveyor belt 5. The conveyor motor 6 drives the conveyor belt 5 to operate, transporting the tobacco leaves forward. The tobacco leaves move with the conveyor belt 5 to the tobacco leaf detection unit 2. The drive motor 25 drives the electric slider 23 on the electric slide rail 22 to move, so that the image recognition camera 24 scans in the width direction of the conveyor belt 5. The high-definition industrial image recognition camera 24 uses autofocus and image stabilization functions to collect tobacco leaf image information and transmits the data to the automated control device 4 in real time. After detection... The tobacco leaves continue to be conveyed by conveyor belt 5 to the tobacco humidification unit 3.

At the same time, the water pump in the water supply device 7 controls the water tank to be filtered through multiple stages and then delivered to the water distribution plate through the water supply pipe 35, and then sprayed out by the atomizing nozzle 34. By adjusting the telescopic cylinder 32's telescopic speed, the spray angle of the atomizing nozzle 34, and the size of the atomized particles, precise and uniform humidification is achieved. The operator inputs operation commands and process parameters through the control buttons 42 (start, stop, emergency stop, parameter adjustment buttons) of the automated control device 4. The display screen 41 displays the equipment operating parameters, fault information, and tobacco leaf detection and processing status in real time.
