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.

Abstract

The invention relates to a cigarette quality testing device which comprises a first negative pressure sensor and a second negative pressure sensor which are used for dilution degree testing, a first preamplifier and a second preamplifier which are used for the dilution degree testing, a hollow head sensor, a hollow head preamplifier, a light sensation sensor, an OTIS profile preamplifier, an A / D module, a single chip and a drive module, wherein the first negative pressure sensor and the second negative pressure sensor are respectively connected with the first preamplifier and the second preamplifier, the hollow head preamplifier is connected with the hollow head sensor; the OTIS profile preamplifier is connected with the light sensation sensor; one end of the A / D module is respectively connected with the first preamplifier, the second preamplifier, the hollow head preamplifier and the OTIS profile preamplifier, the other end of the A / D module is connected with the single chip, and thesingle chip is connected with the drive module. The single chip with high performance is adopted, thereby the function of soft-generation hardware is realized in the signal processing process, the hardware part of the system is simplified, the system reliability and maintainability are increased and further the testing precision of the system is improved.

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 ...
