Algorithm for realizing predictive maintenance and perfection of chopper disk

Abstract

The invention belongs to the technical field of cigarette production, and relates to an algorithm for realizing predictive maintenance and perfection of a chopper disk, which comprises the following steps: S1, acquiring a data set, and establishing a weight index value of a standard cigarette according to the acquired data set; S2, comparing with a standard cigarette to calculate a similarity index of the corresponding standard cigarette; S3, according to the weight index value of the standard cigarette and the similarity index of the standard cigarette, constructing a model for predictive maintenance and perfection of the chopper disk; S4, continuously monitoring the similarity indexes of the cigarettes obtained through the model, observing the distribution of the similarity indexes, andjudging whether the chopper disk needs to be maintained and perfected according to the expression condition of the similarity indexes of the cigarettes on the chopper disk; and S5, correcting the mechanical parameters of the chopper disk according to a feedback result. The algorithm has the advantages that abnormal value early warning can be conducted on cigarette data and the state of the chopperdisk, the quality of cigarettes produced at different positions of the chopper disk is analyzed, and therefore predictive maintenance of the chopper disk is completed.

Description

technical field [0001] The invention belongs to the technical field of cigarette production, and relates to an algorithm for predictive maintenance and improvement of a chopper disc. Background technique [0002] In the existing technical and practical fields, the analysis of the specific state of machine production by smart hoods generally tends to focus on parameter tuning of working condition variables such as fan pressure, temperature and humidity, and their correlation with air, suction resistance, etc. However, currently in the smart hood industry, problems related to the abnormal state of the chopper disc are often neglected to monitor. The existing smart hoods set multiple grooves of different depths on the edge of the chopper disc. Under the normal high-speed starting state, the grooves at different positions on the chopper disc can cut and tighten cigarettes, but the grooves at different positions will also have slight differences in cutting and tightening cigarett...
