Description

technical field [0001] The invention relates to a cigarette, in particular to a cigarette quality detection device. Background technique [0002] The quality inspection of cigarettes includes the detection of the empty end, dilution degree, OTIS appearance of the cigarettes and the elimination of unqualified cigarettes, so as to avoid empty ends, air leakage, excessive or excessive draw resistance in the finished cigarettes produced. When small cigarettes and cigarette rolls are connected, the coil paper and tipping paper are warped to ensure the quality of the finished cigarettes produced. [0003] The traditional cigarette quality inspection uses analog circuits to process and judge the sensor signals of short, dilution, and OTIS appearance to identify unqualified cigarettes. The processing method is simple, and the ability to adapt to the on-site environment in the actual production process is poor. The impact of sensor aging and pressure changes cannot be automatically ...

AI Technical Summary

Problems solved by technology

The processing method is simple, and the ability to adapt to the on-site environment in the actual production process is poor. The influence of sensor aging and pressure changes cannot be automatically adjusted, and there are errors and omissions.

[0004] The detection principles of the prior art for dilution, short, and OTIS appearance are as follows: figure 1 , figure 2 , image 3 Shown: The signal of the negative pressure sensor of the dilution T1 and T2 stations, the short head and the OTIS external photoelectric sensor are compared and judged by the pre-amplification and the analog circuit to distinguish the defects of the cigarettes. Due to the changes of the analog circuit on the scene, such as mechanical The detection of the peak and valley position voltage caused by the change of the position, the aging of the sensor, the change of the installation position, and the change of the negative pressure signal cannot be well adapted, and there will be misjudgment and missed judgment.
