Abstract

The utility model relates to an optical device of online cigarette laser perforated device used for perforating the filter tip or tipping paper of cigarette on cigarette makers, which adopts high frequency pulse laser as laser light source, laser can be turned and transmitted to a light splitting system by a laser steering system which adopts a spectroscope with a light splitting rate of 96% to 99% reflection and a transmissivity of 1%-4% and a detecting element used for power detecting. The light splitting system is adopted to divided laser into two parts. The focusing lens (double focus point or single focus point) of the multiple-way focusing system can be changed to realize the shift of four or two rows perforating. The factory pressure gas after filtered can be perfused into the multiple-way focusing system, protecting the focusing lens, and reducing the laser energy loss caused by dust. The utility model can easily transmit the laser from the rear to the front of the cigarette maker, perforating millipores on the filer tip or tipping paper of cigarette, reaching the aim of reducing the cigarette tar, and has the advantages of compact size, convenient installation, and higher practical value.

Description

The Optical devices of online cigarette laser drilling device

The utility model patent belongs to the cigarette laser drilling device, and particularly a kind of tar content that is used to reduce cigarette is given the Optical devices of the online cigarette laser drilling device of cigarette filter or cigarette yew paper punching on cigarette machine.

Because contain harmful material in the coke tar in cigarette, the tar content that how to reduce cigarette effectively is the important topic of cigarette industry research.Change prescription of Cai Yonging and chemistry fall burnt method and all can not reach desirable effect before this, have obtained good effect after the punching of employing cigarette material, can realize falling burnt 2-3mg under the situation that keeps the original suction flavor of cigarette substantially.The method of punching has mechanical punching, electric spark-erosion perforation and laser boring.Mechanical punching causes the fluctuation of cigarette yew paper air permeability big owing to the instability of punching size, and the amount of falling Jiao is uncontrollable, influences the quality of cigarette; Electric spark-erosion perforation can burn cigarette yew paper, influences the suction flavor of cigarette; Laser boring is the best way, have punching evenly, air permeability is stable, pass is big or small and hole count is easy to advantages such as control.The laser boring of adopting at present has the punching of off-line yew paper, the punching of online yew paper and the punching of online cigarette filter, because the punching of off-line yew paper needs extra mechanical uncoiling and rewinding unit, has influenced the precision of yew paper rewinding, has improved equipment cost simultaneously; Also there is patent to relate to online laser boring at present, its key technology is to adopt 1/4,1/3,1/2 spectroscope that beam of laser is divided into four the tunnel, because 1/4, the 1/3 spectroscope beam split rate that adopts has deviation easily, can cause beam intensity to differ, it is not of uniform size to cause punching, and influences drilling quality, is divided into four road light beams earlier simultaneously and focuses on, it is big to take up room, and is unfavorable for installing on the cigarette machine small space.

The purpose of this utility model provides a kind of Optical devices of online cigarette laser drilling device; the Optical devices of this online cigarette laser drilling device; the beam of laser beam split can be focused into four focuses; volume is little; simple in structure; and, be the Optical devices that aim at online cigarette laser drilling device design with power detection and gas circuit defencive function.

In order to achieve the above object, the technical solution of the utility model is: one, adopt the high-frequency impulse laser instrument as LASER Light Source, and wavelength 10.6um, maximum pulse rate 100kHz the highlyest can get 99 holes (two hesitating) at a cigarette.Two, adopt the laser steering that laser is turned to and be transferred to beam splitting system, and employing beam split rate is that spectroscope and the detecting element that 96%-99% reflects, transmissivity is 1%-4% carries out power detection.Three, adopt beam splitting system that laser is divided into two-way.Four, realize the conversion of four rows or two rounds by the focusing lens (double focus or monofocal point) in the replacing multichannel focusing system.Five, in the multichannel focusing system, feed factory's pneumatics gas that process is filtered, the protection focusing lens, and reduce because the laser energy that the scattering of dust causes loses.

Below in conjunction with accompanying drawing, further describe structure of the present utility model.

Accompanying drawing is a kind of schematic diagram of Optical devices of online laser drilling device.(1) be laser generating system, it is made up of electric-control system 1-1, high-speed pulse laser instrument 1-2 and detection means 1-3, and electric-control system 1-1 sends the high-frequency impulse laser beam by setting Numerical Control high-speed pulse laser instrument 1-2; (2) be Laser Direction Pointer, it is the 96%-99% reflection by a beam split rate, transmissivity is that spectroscope 2-1 and the completely reflecting mirror group 2-2 of 1%-4% forms, when high-speed pulse laser instrument 1-2 sends the high-frequency impulse laser beam and is transferred to spectroscope 2-1, the laser-transmitting of 1%-4% is crossed spectroscope 2-1 and is shone detection means 1-3, produce the signal of telecommunication and feed back to electric-control system, be used for the detection of laser power and the monitoring of laser system, the laser beam of 96%-99% is reflected to completely reflecting mirror group 2-2, reflex to laser light splitter through completely reflecting mirror group 2-3, realizing turning to of laser, detect.(3) be laser light splitter; it forms 3-2 by one 1/2 beam split eyeglass 3-1 and a total reflection eyeglass; laser beam is that 50% laser reflexes to focusing system through 1/2 beam split eyeglass 3-1; 50% laser-transmitting is to total reflection eyeglass 3-2; be reflected to focusing system again; (4) be the multichannel focusing system; it is made up of two identical double focus focusing lens (or monofocal point focusing eyeglass) 4-1 and pneumatics air flue 4-2; double focusing point focus lens (or monofocal point focusing eyeglass) 4-1 can regulate to the distance of cigarette material; beam of laser is focused into identical (or the one) spot of two energy in the cigarette material surface; cigarette material is got micropore; enter by air duct 4-2 through the factory air compressed gas that filters; discharge along beam direction; keep the laser exit 0.1-0.2 of a place atmospheric malleation; the smog that produces when dispelling workshop dust and punching, the protection focusing lens, and reduce because the laser energy loss that the scattering of dust causes.

Because the utility model, adopt the laser transfer, very simply laser is transferred to the cigarette machine front from the cigarette machine back side, and adopt the double focus focusing lens that the two-way light beam is divided into four road light beams, guaranteed four road laser energy unanimities, and volume is little, easy for installation.
