Graphical hole tipping paper punching equipment

Abstract

The invention discloses graphical hole tipping paper punching equipment. The graphical hole tipping paper punching equipment comprises a paper feeding system, a pulse laser device, a beam expander and a reflection type diffractometer. According to the graphical hole tipping paper punching equipment, the reflection type diffractometer is used for enabling a pulse laser with the beam expanded to be used as incident light, and the incident light is focused on the surface of the tipping paper in a reflecting mode so that a plurality of holes in independent shapes can be punched; the reflection surface of the reflection type diffractometer has a coaxial reappearance function and has predetermined diffraction efficiency and is formed due to the fact that a step or continuous embossment structure is generated on a substrate through etching based on the diffraction optical theory, by means of the computer aided design and through the super-large-scale integrated circuit manufacturing technology. The pulse laser with high peak energy is output by the pulse laser device and enters the surface of the reflection type diffractometer through the beam expander, the incident light can be focused on the surface of the tipping paper by the reflection type diffractometer in the reflecting mode, and then the holes with diameters of 20-500 microns are punched. The graphical hole tipping paper punching equipment is good in stability and strong in generality. The holes punched with the equipment are good in air permeability. Security degree is high.

Description

technical field [0001] The invention relates to a laser processing device, in particular to a punching device for loosening paper for a filter tip. Background technique [0002] Studies have shown that air dilution can reduce people's intake of harmful substances such as tar, nicotine, and carbon monoxide during smoking, so high-permeability cigarette paper and pre-punched tipping paper (tip paper) came into being. Especially tipping paper punching technology has achieved rapid development in recent years, because among various methods, the method of quantitatively punching tipping paper with laser is the simplest and most effective. [0003] The punching process of tipping paper has obvious effects on reducing coke, and has been widely adopted by domestic and foreign tobacco companies. At present, the punching of tipping paper mainly includes four methods: mechanical punching, electric spark punching, electrostatic punching and laser punching. Among them, laser drilling i...

Problems solved by technology

Although existing patents have proposed anti-counterfeiting methods using micro-hole patterns to form different shapes or curves, the overall flexibility is not high, the shape of the holes cannot be changed, and it is very troublesome to adjust the shape of the pattern
