Anti-counterfeiting laser boring method and device of cigarette tipping paper

Abstract

The invention discloses an anti-counterfeiting laser boring method of cigarette tipping paper, which comprises the following steps: leading a pulse laser beam outputted by a pulse laser to sequentially pass through a two-dimensional acousto-optic deflection system and an F-theta lens for transmission and focusing, and forming a pulsed focal spot on the surface of the tipping paper in continuous motion; and simultaneously leading a control system to emit a control signal for respectively carrying out centralized control on light-emitting time sequence and pulse interval time of the pulse laser and light beam deflection angles of an X-axis acousto-optic deflector and a Y-axis acousto-optic deflector in the acousto-optic deflection system at different time according to the motion velocity of the tipping paper and information of a pattern, characters or a curve which is inputted into a boring pattern and character data storage module in advance, and boring small holes which are arranged and distributed like the required pattern, the characters or the curve on the surface of the tipping paper by being matched with the continuous motion of the tipping paper. The invention simultaneously provides a device capable of realizing the method, and the device has simple structure, stable working and high processing efficiency.

Description

technical field [0001] The invention relates to an anti-counterfeit laser drilling method and device for cigarette tipping paper. Background technique [0002] It is a generally accepted fact that smoking is harmful to health, and effectively reducing tar content is of great significance to improving the health of smoking groups. In recent years, reducing the amount of tar in cigarettes has become a research hotspot in the tobacco industry. Cigarette manufacturers in various countries have successively invested a lot of manpower, material resources and huge funds to conduct extensive and in-depth research on the technology, theory, method and practical application of reducing the tar content of cigarettes, and have achieved a large number of scientific research results; many achievements It has been successfully applied in actual production and has obtained huge economic and social benefits. [0003] Cigarette tipping paper is used as the cigarette packaging material for t...
