Description
Technical Field
The invention relates to the field of tobacco shred pneumatic conveying control, in particular to an online monitoring and diagnosing system of an SACU tobacco shred pneumatic conveying controller.
Background
The tobacco manufacturing mainly comprises three links of shredding, rolling and connecting and packaging. The finished cut tobacco formed after the tobacco leaf is cut in the tobacco shred making process is temporarily placed in a cut tobacco storage cabinet for subsequent conveying to a cigarette making machine for rolling connection, and the conveying process is called cut tobacco conveying. At present, the cigarette enterprise mainly comprises two automatic wire feeding modes except manual wire feeding, wherein one mode is wind wire feeding, and the other mode is rail trolley wire feeding. Because the wind-force send silk possess clean, high-efficient, the environmental protection characteristic, adopted by most cigarette enterprises at present. Nevertheless, there are still some problems in pneumatic feeding, such as certain damage to the cut tobacco and increased breakage of cut tobacco. This problem has been unsolved.
The SACU wind power cut tobacco feeding controller is used for wind power conveying of cut tobacco in cigarette production, and achieves the purposes of accurately controlling the wind conveying speed of the cut tobacco and reducing the breaking rate of the cut tobacco during wind conveying by controlling the negative pressure and the wind speed in the negative pressure adsorption pipe. In the use process of the conventional wind-driven wire feeding controller, the operation states of the wind-driven wire feeding controller, such as wind speed, valve opening, a servo motor, a servo controller, the temperature in a cavity, the pressure and gas leakage value of a pipeline, and the like, need to be monitored so as to timely adjust and maintain the controller which causes problems.
At present, a monitoring system of an SACU wind power wire feeding controller manually inquires the wind power speed of tobacco shreds and the running state information of a control system, and workers analyze data to judge whether the wind power wire feeding system runs normally. The disadvantages of the existing method are that: 1) if the tobacco shred pneumatic conveying speed exceeds the standard, workers cannot be warned in time, and no relevant records exist for inquiring; 2) when the SACU wind power cut tobacco feeding controller works unstably (for example, a valve is slightly stuck due to sundries such as tobacco powder), a worker cannot find out at the first time, so that the problems of large deviation, instability and the like of the wind power feeding speed of cut tobacco can be caused, and the cut tobacco conveying quality is influenced; 3) the data from previous measurements cannot be stored and predictive maintenance of the equipment by analyzing the data is not possible.
