Problems solved by technology

At present, the prolific sampling inspection method is used for the production of tipping paper. After each plate of tipping paper is punched, a section is torn and tested with a special air permeability detector. The test results can only reflect a small section of tipping paper. The air permeability of the entire roll of tipping paper cannot be grasped in real time, and the punching quality of the entire roll of tipping paper cannot be guaranteed, and offline detection is very inconvenient, poor in timeliness, and low in work efficiency

Embodiment 1

[0020] This embodiment describes a method for detecting air permeability of tipping paper, and its structural principle block diagram is as follows figure 1 As shown, the specific detection steps are as follows:

[0021] The comparison data of luminous flux and tipping paper air permeability are stored in the database; the laser light source is used to irradiate the perforated tipping paper vertically, and the photoelectric sensor is used on the other side of the perforated tipping paper to receive the optical signal from the laser light source, and the photoelectric sensor is obtained. The luminous flux variable is sent to the processing system; the processing system compares the luminous flux variable obtained by the photoelectric sensor with the data pre-stored in the database, and obtains the air permeability of the tipping paper corresponding to the currently measured luminous flux variable. The air permeability of the paper can reflect the current air permeability of the...

Embodiment 2

[0023] This embodiment provides a kind of tipping paper air permeability detection device corresponding to the above method, which can be divided into two parts, the measurement end and the processing end, such as figure 2 The shown measuring end includes a U-shaped support 1, a collimated laser 2, and a photoelectric sensor 4.

Abstract

The invention provides a method and a device for detecting the air permeability of tipping paper. A light source with high stability and uniformly distributed light intensity is adopted to directly irradiate the perforated tipping paper which moves at a high speed; a photoelectric sensor is arranged at a position below the tipping paper, which is over against the light source; light is directly focused on the photoelectric sensor through a hole on the tipping paper; the amount of the air permeated correspondingly to the air permeability of the tipping paper is converted into the intermediate variable luminous flux; the luminous flux is directly measured by the photoelectric sensor; a corresponding value relation between the air permeability of the tipping paper and the luminous flux is prestored in a database; after the measured luminous flux, i.e. real-time luminous flux data, is transmitted to a processing system, the value of the luminous flux can be compared from the database in which the data is prestored by the processing system, so that the air permeability of the corresponding perforated tipping paper is obtained, and thus, the whole-course real-time detection on the air permeability of the perforated tipping paper which moves at the high speed can be realized, an air permeability index of a product is accurate and reliable and the quality is effectively ensured.

Description

technical field [0001] The invention relates to a method and a device for detecting the quality of tipping paper, in particular to a method for detecting the air permeability of tipping paper and a device for detecting the same. Background technique [0002] Tipping paper is tipping paper, which is used as the outer wrapping paper of cigarette filters and is specially used by cigarette factories, and belongs to special industrial paper. In recent years, researchers have found that the use of perforated tipping paper can effectively control the tar content of cigarettes. As a newer and more effective tar reduction technology, this technology has developed rapidly, and the air permeability of perforated tipping paper directly affects the tar content of cigarettes. Therefore, it is particularly important to precisely control the air permeability of the tipping paper. At present, the prolific sampling inspection method is used for the production of tipping paper. After each pla...
