Problems solved by technology

However, the shortcoming of this punching machine is precisely because of the use of 2N independent punching heads, and each punching head only corresponds to one pulsed laser focused spot output, resulting in a relatively complex structure of the device and a large volume. If the processing efficiency of this kind of punching machine is not enough, the number of punching heads must be increased, which will make the structure of the whole machine more complicated

Embodiment 1

[0038] Example 1: First combine figure 1 , figure 2 As shown, the double-head integrated laser drilling device for cigarette tipping paper provided in this embodiment includes a laser 1, a control system 3, a polygonal mirror beam splitting mechanism 4, a focusing mechanism, and a paper-feeding mechanism that drives the tipping paper 10 to move continuously. 7. The tipping paper online speed detection device 11 and the laser cooling system 12 are jointly composed. Where: the laser 1 is a high-power continuous CO 2 Laser, its output power is continuously variable from 50 to 4000 watts, and the laser output wavelength is 10.6 μm. The polygonal mirror beam splitting mechanism 4 among the present embodiment is made up of polygonal mirror 401, the high-speed motor 406 that drives polygonal mirror 401 to rotate, total reflection mirror group, the first reflection that is used for the continuous laser beam 2 that laser 1 sends is focused on a certain working surface of polygonal m...

Embodiment 2

[0046] Embodiment 2: as Figure 4 As shown, the double-head integrated laser drilling device for cigarette tipping paper provided by this embodiment has the same external structure as that of Embodiment 1, but the difference is that it uses the first reflection type in the polygonal mirror beam splitting mechanism 4 involved in Embodiment 1 The focusing lens 403 is replaced by the first transmissive focusing lens 402, and the internal structures of the two integrated punching heads 601 and 602 are redesigned at the same time, specifically taking the first integrated punching head 601 as an example, this embodiment N=3 closely arranged focusing lenses 901, 902, 903 ( Figure 4 The high-speed motor 406 connected to one side of the polygon mirror 401 is omitted). The working principle of this embodiment can be found in figure 1 , figure 2 and Figure 4 The description shown is as follows: the continuous laser beam 2 output by the laser 1 enters the polygonal mirror beam spli...

Embodiment 3

[0047] Embodiment 3: as Figure 5As shown, the double-head integrated laser drilling device for cigarette tipping paper provided by this embodiment has the same external structure as that of Embodiment 1, but the difference is that it uses the first reflection type in the polygonal mirror beam splitting mechanism 4 involved in Embodiment 1 The focusing mirror 403 is replaced by the first transmissive focusing mirror 402, and the second transmissive focusing mirror 7 is replaced by the second parabolic reflective focusing mirror 5; All have been redesigned, specifically taking the first integrated punching head 601 as an example, in this embodiment, N=3 closely arranged focusing lenses 901, 902, 903 ( Figure 4 The high-speed motor 406 connected to one side of the polygon mirror 401 is omitted). The working principle of this embodiment can be found in figure 1 , figure 2 and Figure 5 The description shown is as follows: the continuous laser beam 2 output by the laser 1 en...

Abstract

The invention discloses a double-head integrated laser drilling device for cigarette tipping paper, which comprises a laser, a polygon prism light splitting mechanism, a focusing mechanism and a paper feeding mechanism for driving the continuous motion of the tipping paper; and the double-head integrated laser drilling device is characterized in that the focusing mechanism consists of a first integrated drilling head and a second integrated drilling head which are arranged along the width direction of the tipping paper, each integrated drilling head can correspondingly output N focus light spots by a group of independent optical focusing elements arranged therein, and the two integrated drilling heads can form 2 multiplied N rows of densely arranged small holes on the moving tipping paper, wherein N is not less than 1. The double-head integrated laser drilling device adopts the technology of the integrated drilling heads to simplify a plurality of separate drilling heads into two independent integrated drill heads, and each integrated drilling head can correspondingly output the N focus light spots, wherein N is not less than 1, thereby ensuring the processing efficiency and simultaneously achieving the purpose of simplifying the structure of the device.

Description

technical field [0001] The invention relates to a double-head laser punching device for cigarette tipping paper. Background technique [0002] It is a generally accepted fact that smoking is harmful to health, and reducing tar content is of great significance to improving the health of smoking groups. Cigarette manufacturers in various countries have invested a lot of manpower, material resources and huge funds to conduct extensive and in-depth research on the theoretical methods, technologies and practical applications of reducing the tar content of cigarettes, and have developed a variety of tar reduction technologies. [0003] Cigarette tipping paper is used as the special outer packaging paper for cigarette filters. It was once named tipping paper because of its appearance similar to pine wood grain. The principle of filter ventilation and dilution technology is to allow external air to enter the filter when smoking cigarettes by punching holes in the tipping paper, usi...
