Tightness detection device of transparent paper for cigarette packing

Abstract

The invention discloses a tightness detection device of transparent paper for cigarette packing. The tightness detection device comprises a negative pressure generation device and a sealing device, wherein the negative pressure generation device comprises a vacuum pump, the sealing device comprises a second sealing vessel and a first sealing vessel for containing water and cigarette packets to be detected, the vacuum pump is connected with the second sealing vessel by an air pipe, and the first sealing vessel and the second sealing vessel are connected by an air pipe. According to the tightness detection device of transparent paper for cigarette packing, a negative pressure soaking method is adopted to detect the tightness of the packaging transparent paper, flexible package testing can be carried out, rigid package detection also can be carried out, the leakage position and the tightness degree of the transparent paper for cigarette packing can be tested, the measurement of the tightness of transparent paper for cigarette packing can be perfected, and the operating convenience and the detecting accuracy are achieved.

Description

technical field [0001] The invention relates to the technical field of cigarette equipment, in particular to a device for detecting the airtightness of transparent paper in cigarette packaging. Background technique [0002] The airtightness of the transparent paper of cigarette packaging is an important physical index in the production process of cigarettes. A good airtightness can effectively prevent the leakage of cigarette flavor when cigarettes are stored for a long time, and reduce the influence of external temperature and humidity on cigarettes and the influence of moisture. Loss, prolong the storage time of cigarettes. Cigarettes with poor airtightness will cause the fragrance of cigarettes to leak due to long storage time, and changes in the external environment will also lead to dryness and mildew of cigarettes, which seriously affects the quality of cigarettes. In the production of cigarettes, due to various factors, during the process of folding and forming the c...

Cigarettes with poor airtightness will leak the flavor of cigarettes due to long storage time, and changes in the external environment will also lead to dryness and mildew of cigarettes, which seriously affects the quality of cigarettes

In the production of cigarettes, due to various factors, during the process of folding and forming the cigarette pack film and transporting it to the ironing mechanism, there may be problems such as looseness, wrinkling, air bubbles on the side of the cigarette pack film, and non-adherence. , thus affecting the sealing degree of the transparent paper of the cigarette package

[0003] According to the relevant industry standard "YC / T140-1998 Measuring Inflation Method for the Sealing Degree of Cigarette Small Packets" issued in 1998, the existing detection device measures the airtightness of the cigarette case by the inflation method, but due to the limitation of the inflation method Limitations: During the detection of hard packs of cigarettes, the airflow cannot pass through the edges of the hard packs, so this method is only suitable for the measurement of soft packs in most cases, and cannot measure the leakage position of cigarette packs
