Abstract

The invention belongs to the field of cigarette packet packing, in particular to a detection method of cigarette packet packing tightness. The detection method is characterized in that the method is based on pressure sensing cigarette packing tightness detection, and the position of gas leaking can be detected. Compared with the prior industrial standard YC/T140-1998 detection charge method to determine package seal, the tightness of soft and hard packages of cigarette are simultaneously detected, and accuracy is high; meanwhile, the gas leaking position is found. The method is easy to operate and achieve. According to the detecting method, the tightness of cigarette packing is improved by moderately adjusting technical parameters of cigarette packing, thereby the risk of cigarette mildew in long-time storage and transportation. The detection method of cigarette box packing tightness has important significance for cigarette manufacturers to control cigarette quality and protect cigarette storage time, protect consumers' benefit and establish Chinese cigarette image.

Description

technical field [0001] The invention belongs to the technical field of cigarette detection, and relates to a method capable of detecting the sealing degree and leakage position of a cigarette small box package. Background technique [0002] Cigarette packaging is the last production link of finished cigarettes. With the development of production technology, the cigarette packaging process mainly uses machines to seal the folds at both ends of the cigarette box. When cigarettes with poor airtightness are stored for a long time, mildew will appear in a humid environment, and the cigarettes will be cracked and brittle in a dry environment. At the same time, the fragrance of the cigarettes will also leak a lot, which directly affects consumers interests and reputation of cigarette manufacturers. In recent years, some consumers have suggested that some cigarettes have become mildewed and cracked. It can be seen that measuring the airtightness of cigarette packages is crucial t...
