The invention discloses an online monitoring method for measuring accuracy of a tobacco feeding and flavoring flow meter. The online monitoring method includes the following steps: adding spices; filling in advance; analyzing data; formally feeding; collecting data; monitoring the accuracy of the flow meter; analyzing dotting; and proactively calibrating the flow meter. The method is mainly used for calculating the measuring accuracy of the flow meter by using weight variable quantity of a spice and essence storage pot and accumulation quantity of the flow meter during the production process of feeding and flavoring tobacco, utilizing statistical process control to analyze a controlled state of the measuring accuracy of the flow meter, and emphasizing preventive judgment, and thereby the online monitoring method solves the problems of long spot check or inspection time and production influencing, and effectively overcomes the shortcoming that potential quality hazards are difficult to discover in other online monitoring methods due to the fact that other online monitoring methods can only perform decidability monitoring.
Description
technical field [0001] The invention belongs to the technical field of tobacco, and in particular relates to an online monitoring method for metering precision of a tobacco feeding and flavoring flowmeter. Background technique [0002] In the process of making shredded cigarettes, adding ingredients and flavoring is one of the key links in the shredded process. The accuracy of adding ingredients and flavoring directly affects the sensory quality of cigarettes. Therefore, this process is regarded as a key core process by the tobacco industry. The working process of feeding and flavoring process is as follows: the system starts to work, pre-fills, the gear pump runs, the spices and essences are pressed into the pipeline, the one-way valve is opened, the delay is a certain time, the pre-filling is completed, and the system enters the waiting state. When the electronic scale detects the tobacco material information, the measured tobacco material flow signal is input to the PLC c...
