On-line monitoring method for running state of cigarette making machine

Abstract

The invention provides an on-line monitoring method for the running state of a cigarette making machine, which comprises the following steps: taking a motor, a primary transmission shaft and a secondary transmission shaft of cigarette making machine equipment as key detection points for vibration and temperature detection, and taking a vibration signal and a temperature signal collected on site as monitoring parameters; setting a database server, and performing data storage and processing on the vibration signals and the temperature signals monitored by the key detection points in real time to form a vibration change curve graph and a temperature change curve graph; extracting fault characteristic indexes according to the vibration change curve graph and the temperature change curve graph, wherein the fault characteristic indexes comprise the vibration speed, the vibration displacement, the vibration acceleration, the operation temperature and the temperature change value; and setting an early warning threshold value and an alarm threshold value, performing pre-judgment alarm when the fault characteristic index is greater than the early warning threshold value, and performing fault alarm when the fault characteristic index is greater than the alarm threshold value. The maintenance efficiency can be improved, powerful guarantee is provided for equipment management, and the production and operation cost is reduced.

Description

technical field [0001] The invention relates to the technical field of cigarette production management, in particular to an online monitoring method for the running state of a cigarette making machine. Background technique [0002] Cigarette machine is an automatic mechanical equipment for producing cigarettes. The cigarette machine has a long service life, with a general lifespan of about 15 years. Long-term operation will cause some parts to age or even fail, affecting its normal function. In order to ensure the safety and normal operation of the equipment, it is necessary to monitor the hidden faults such as equipment temperature, mechanical wear, and mechanical fatigue of the cigarette making machine equipment, so as to give early warning of high temperature and wear at key points. In order to realize the early warning and intelligent diagnosis of equipment failure. Therefore, how to monitor and evaluate the health status of the cigarette group is of great significance....
