Abstract

In cigarette manufacturers, the detection of cigarette quality has always been the key problem in the entire industry's production chain. The efficiency and accuracy of detection technology are directly related to product quality and furthermore, it will affect the credibility and economic benefits of the entire enterprise. For the cigarettes with blasting beads, in order to ensure the safety of smokers during smoking and to obtain a better experience, determining the presence or absence, location, and damage condition of beads in the cigarette filter is critical. Therefore, it is necessary to test the beads in the manufacturing process of the cigarette, thereby timely remove the unqualified product. In this paper, a nondestructive testing method based on reflective terahertz time-domain spectral imaging system is proposed, which can easily evaluate the presence or absence approximate position and damage condition of beads in the cigarettes filter. To lay a foundation for further accurate and effective measurement of the positional offset of beads and to evaluate the damage condition of beads, it is of great significance to improve the production efficiency and tobacco quality of the tobacco factory.
