[0003] At present, in the production process, there is no state monitoring method for the feeding system. Only when the feeding function fails and the process requirements cannot be met, the feeding system is repaired and maintained. This method of after-the-fact maintenance cannot strictly guarantee the feeding Normal accuracy

Embodiment Construction
[0051] The invention is described in detail below in conjunction with accompanying drawing:
[0052] A method for preventing abnormal feeding of a blade feeder, comprising the following steps:
[0053] Step 1. Use the PLC controller to realize the data acquisition of the operating frequency of the feeding pump, the feeding flow rate of the flow meter, the pressure of the feeding pipeline and the steam pressure of the atomizing nozzle;
[0054] Step 2 compares the collected feeding pipeline pressure with the theoretical value in the pipeline pressure characteristic curve, and the theoretical value is obtained from the corresponding table according to different types of feed liquids and feed liquid flow rates. If the pipeline pressure is lower or higher than the theoretical value, 1 point will be deducted for every 1% lower (higher) than 5%, and the deduction will be doubled, that is, 2 points will be deducted for every 5% lower. The overall reduction of pipeline pressure is; ...

The invention discloses a method preventing abnormal charging of a blade charging machine. The method comprises the steps that data collection is achieved through a PLC; collected pipeline pressure is compared with a theoretical value in a pipeline pressure characteristic curve, wherein the theoretical value is obtained by inquiring a table; if the pipeline pressure is smaller than or larger than the theoretical value, warning information is sent; collected feed liquid flow quantity in a charging pipe is compared with theoretical flow quantity, wherein the theoretical flow quantity is obtained by inquiring a corresponding table; if the feed liquid flow quantity is lower than the theoretical flow quantity, warning information is sent; collected atomization steam pressure is compared with a technological requirement value, and warning information is sent if the atomization steam pressure is smaller than the technological requirement value; after production is finished, the average running frequency of a charging pump is calculated, the average frequency is compared with an ideal area, and warning information is sent if the average frequency is larger than the ideal area; a total score is calculated, and warning information is sent if the deduction score is larger than set score. According to the method preventing abnormal charging of the blade charging machine, health monitoring of a charging system of the blade charging machine is achieved, and therefore system hidden dangers can be found timely.
Description
technical field [0001] The invention relates to a method for preventing abnormal feeding of a blade feeder. Background technique [0002] As the key equipment for cigarette production, the leaf feeder is responsible for uniformly applying the feed liquid to the tobacco leaves according to the formula requirements, and making the tobacco leaves reach the temperature required by the process to promote the absorption of the feed liquid. As the main indicator of the feeder, the feeding accuracy has a great influence on the quality of cigarettes. [0003] At present, in the production process, there is no state monitoring method for the feeding system. Only when the feeding function fails and the process requirements cannot be met, the feeding system is repaired and maintained. This method of after-the-fact maintenance cannot strictly guarantee the feeding Accuracy is normal. Contents of the invention [0004] In order to solve the shortcomings of the existing technology, the...
