Dear colleague,

As the final output product of tobacco agriculture, the appearance quality of cigarette is the key link to

control. However, there is no special detection equipment for the whole appearance defect detection of tobacco,

while it mainly depends on manual detection, leading to the test standard is not unique and the test data cannot be stored effectively. In this research, the shape characteristic and appearance inspection requirements of cigarette were analyzed with black-box method. Then, a kind of cigarette appearance quality inspection equipment was designed, and the experimental data of the equipment is analyzed with Design-Expert11. The results show that the device can image the appearance of cigarette completely. The optimum parameters of the equipment are: the lifting speed of slide plate is 0.3m/s, the angle of transition plate is 40 °, the displacement speed of roller is 0.045 m/s, the movement speed of the slide plate is 0.4 m/s, the expansion speed of the cylinder is 20mm/s, the Spring Coefficient is 3n/s, the angle of the light source is 10 ° , and the height difference between the light source and the cigarette is 30mm. The equipment can satisfy the requirements of cigarette appearance detection and provide a reference for cylindrical object appearance detection.

 We look forward to receiving your contributions.
