Air pressure detection device and method for cigarette making and plug assembling machine

The invention discloses an air pressure detection device and method for a cigarette making and plug assembling machine, and the method comprises the steps: an air pressure signal sensor monitors the real-time air pressure of an air pressure pipeline of a cigarette conveying spider hand structure of a roll paper forming machine of the cigarette making and plug assembling machine, and inputs an air pressure signal to an industrial personal computer; the industrial personal computer obtains the deviation degree by comparing the monitored real-time air pressure with the positive pressure normal working value and the negative pressure normal working value, the deviation degree is normal within a first preset value, the deviation degree is abnormal when the deviation degree is larger than the first preset value and smaller than a second preset value, and the deviation degree is serious abnormal when the deviation degree is larger than or equal to the second preset value.
