Description

Technical Field

[0001] This invention relates to automated control technology in tobacco production, specifically to a system for monitoring the atomization effect of a tobacco feeding machine. Background Technology

[0002] The feeding process is a crucial step in cigarette manufacturing. The tobacco leaves or shreds are evenly loosened by the rotation of the feeding cylinder. The flavorings are atomized by steam or compressed air through atomizing nozzles and evenly sprayed onto the surface of the tobacco leaves or shreds, thus achieving the water and flavoring process. Because the nozzles typically operate within a largely enclosed feeding cylinder, the spray angle and distance of the induced steam cannot be directly observed, and personnel cannot enter the cylinder for inspection. Therefore, even if atomization is poor or droplets of flavoring fall, it is impossible to observe and resolve the issue. The atomization effect is difficult to determine, and there are no qualitative or quantitative standards for atomization effect and atomization angle, making it impossible to effectively verify quality. The feeding drum environment is characterized by heavy smoke and dust and viscous liquid, which easily adhere to the camera, making the video captured by the camera unclear. This problem seriously hinders the application of machine vision technology in drum feeding. At the same time, when water droplets are on the upper surface of the protective cover, the smoke and dust fall on it and mix with the water to form dirt. This dirt breeds bacteria in the basically closed feeding drum equipment, affecting the cigarette processing effect. To address this, we propose an atomization effect monitoring system for cigarette feeding machines. Summary of the Invention

[0003] The purpose of this invention is to provide a system for monitoring the atomization effect of a filament feeding machine, so as to overcome the above-mentioned shortcomings in the prior art.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a system for monitoring the atomization effect of a filament feeding machine, comprising a monitoring device, wherein the monitoring device includes a monitoring unit, a database, a central processing unit, a video filtering unit, a video analysis unit, a problem classification unit, a control unit, an instruction sending unit, an alarm unit, and an execution unit;

[0005] The control unit includes a droplet velocity capture module, a droplet distribution recognition module, a droplet diameter recognition module, and a droplet size recognition module;

[0006] The control unit analyzes droplet diameter, droplet size, droplet velocity, and droplet distribution indicators to determine whether the pressure of the atomization source of the atomized liquid is appropriate.

[0007] The video filtering unit is used to automatically filter the videos captured by the monitoring unit, automatically delete videos during idle periods, and restore the clarity of the captured videos.

[0008] Furthermore, the droplet velocity capture module is used to rapidly capture the spray velocity of the atomized liquid.

[0009] The droplet distribution recognition module is used to identify and process the spraying surface of the atomized liquid, and adjust the distribution of the liquid. It is also used to identify the uniformity of the droplet distribution in the atomization field after atomization. During the feeding process of tobacco leaves, the uniformity of droplet size distribution is related to the uniform absorption of the liquid by the tobacco leaves, which has a great impact on the final feeding effect. When the atomization angle is too small, the atomization field of the liquid cannot completely cover the spraying surface of the tobacco leaves, and some tobacco leaves cannot come into contact with the liquid, resulting in uneven feeding. However, when the atomization angle is too large, the atomization field of the liquid exceeds the spraying surface of the tobacco leaves, and the liquid is sprayed into the area without tobacco leaves, or even directly sprayed onto the drum wall, resulting in waste of liquid and reducing the utilization rate of the liquid.

[0010] The droplet diameter recognition module and droplet size recognition module are used to scan, analyze and identify the diameter of the droplets formed after atomization by the nozzle. In the cigarette making and feeding process, the smaller the diameter of the droplets after atomization by the nozzle, the easier it is to contact and absorb the rotating and scattered tobacco leaves, and the better the feeding effect of the tobacco leaves. When the diameter of the droplets is very large, it will cause excessive feeding on the surface of the tobacco leaves and uneven distribution of the liquid on the surface of the tobacco leaves. However, when the diameter of the liquid atomization is too small, it will be affected by the flow field inside the roller and cause dispersion, resulting in waste of liquid.

[0011] Furthermore, the output of the monitoring unit is connected to the input of the database, the output of the database is connected to the input of the central processing unit and the video filtering unit, the output of the central processing unit is connected to the input of the video filtering unit, the video analysis unit, the instruction sending unit and the database, and the output of the video filtering unit is connected to the input of the database and the video analysis unit.

[0016] Furthermore, the telescopic mechanism includes a movable block threadedly connected to two reciprocating lead screws. Both ends of the two movable blocks are rotatably connected to telescopic fences. The top of the telescopic fences is symmetrically fixedly connected to sliding rods. A connecting plate is movably sleeved on the sliding rods. A collar is fixedly connected to the top of the connecting plate. Scrapers are fixedly connected to the inner sides of multiple collars.

[0018] One end of the protective cover has an installation hole, and a protective glass is embedded inside the installation hole. One side of the brush bristles is closely fitted to the outer side of the protective glass. Two sets of guide plates are symmetrically fixedly connected to the outer side of the protective cover.

[0032] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0033] Example 1:

[0034] Please see Figure 1-8 A system for monitoring the atomization effect of a filament feeding machine includes monitoring equipment, which includes a monitoring unit, a database, a central processing unit, a video filtering unit, a video analysis unit, a problem classification unit, a control unit, an instruction sending unit, an alarm unit, and an execution unit.

[0035] The control unit includes a droplet velocity capture module, a droplet distribution recognition module, a droplet diameter recognition module, and a droplet size recognition module;

[0036] The control unit analyzes droplet diameter, droplet size, droplet velocity, and droplet distribution indicators to determine whether the pressure of the atomization source of the atomized liquid is appropriate.

[0037] The video filtering unit is used to automatically filter the videos captured by the monitoring unit, automatically delete videos during idle periods, and restore the clarity of the captured videos.

[0038] In this invention, a droplet velocity capture module is used to rapidly capture the spray velocity of the atomized liquid.

[0039] The droplet distribution recognition module is used to identify and process the spraying surface of the atomized liquid, and adjust the distribution of the liquid. It is also used to identify the uniformity of the droplet distribution in the atomization field after atomization. During the feeding process of tobacco leaves, the uniformity of droplet size distribution is related to the uniform absorption of the liquid by the tobacco leaves, which has a great impact on the final feeding effect. When the atomization angle is too small, the atomization field of the liquid cannot completely cover the spraying surface of the tobacco leaves, and some tobacco leaves cannot come into contact with the liquid, resulting in uneven feeding. However, when the atomization angle is too large, the atomization field of the liquid exceeds the spraying surface of the tobacco leaves, and the liquid is sprayed into the area without tobacco leaves, or even directly sprayed onto the drum wall, resulting in waste of liquid and reducing the utilization rate of the liquid.

[0040] The droplet diameter recognition module and droplet size recognition module are used to scan, analyze and identify the diameter of the droplets formed after atomization by the nozzle. In the cigarette making and feeding process, the smaller the diameter of the droplets after atomization by the nozzle, the easier it is to contact and absorb the rotating and scattered tobacco leaves, and the better the feeding effect of the tobacco leaves. When the diameter of the droplets is very large, it will cause excessive feeding on the surface of the tobacco leaves and uneven distribution of the liquid on the surface of the tobacco leaves. However, when the diameter of the liquid atomization is too small, it will be affected by the flow field inside the roller and cause dispersion, resulting in waste of liquid.

Scrapers are fixedly connected to the inner sides of multiple collars 13. The other side of multiple scrapers is closely attached to the outer surface of the protective cover 2.

The dual-axis motor 3 starts and drives the fan blade 4 and the rotating plate 5 to rotate synchronously through the two output shafts. The rotation of the rotating plate 5 drives the first connecting block 15 to move up and down synchronously through the first traction plate 6. The movement of the first connecting block 15 drives the connecting plate 14 to swing through the connecting rod.
