The invention discloses a cigarette shape detection signal calibration device and system for a double-channel cigarette making and plug assembling machine. A gear selection switch is connected to the signal output end of a double-channel cigarette making and plug assembling machine and has three gears. When cigarette shape detection signal calibration is carried out, two gears respectively control an input front cigarette shape detection signal and an input rear cigarette shape detection signal to be input into a filter, the filter and an operational amplifier circuit filter and amplify the signals, the signals are output to a second single-chip microcomputer through an A / D converter, and when the second single-chip microcomputer judges that the cigarette shape detection signals exceed an expected value, the second single-chip microcomputer outputs a control signal to an alarm so as to control the alarm to output a calibration early warning signal. When voltage calibration is carried out according to the early warning signal, a coarse adjustment amplifier and / or a fine adjustment amplifier are / is adjusted to calibrate a voltage value and store the voltage value in the first single-chip microcomputer, and a liquid crystal digital display voltmeter obtains the calibrated voltage value from the first single-chip microcomputer and displays the calibrated voltage value. According to the device and the system, cigarette shape detection signal calibration of a double-channel cigarette making and plug assembling machine is realized.
Description
technical field [0001] The invention belongs to the field of detecting the shape of cigarettes of cigarette crimpers in the tobacco industry, and in particular relates to a signal calibration device and system for detecting the shape of cigarettes of double-channel crimpers. Background technique [0002] Cigarette machine cigarette shape inspection system is to detect unqualified cigarettes with folds, sticky paper, flattened, cracked mouths, etc. in high-speed flowing cigarettes on the production line online, and remove them in real time to ensure the product quality of finished cigarettes. [0003] At present, the cigarette shape detection sensor adopts photoelectric technology, and the output signal range is analog within 0-15VDC. According to the field installation error, sensor difference and attenuation during use, the two signal ranges are inconsistent. Corresponding modules are required to adjust the reference voltage and magnification of the front and rear channels,...
