Embodiment Construction

[0042] The invention provides two laser drilling methods for cigarette tipping paper, which are a rotating polygonal prism type drilling method and a galvanometer type drilling method. The invention also provides two devices for realizing the method.

[0043] The present invention will be further described below in conjunction with embodiments and drawings.

[0044] 1. Rotating polygonal prism drilling method

[0045] See figure 1 The method is: the continuous laser beam output by the continuous laser 1 is split by a set of optical half mirror 4 and the total mirror 5, and then scanned and split by a rotating polygonal prism 7 (hereinafter referred to as the polygonal prism 7) to form a multi-channel timing sequence There are successively pulsed laser beams, which are respectively focused by multiple focusing heads 8 to form multiple focused light spots that emit light successively on the surface of the continuously moving tipping paper 9. These focused light spots make the tippin...

Abstract

The invention provides two methods and equipment for laser punching of cigarette tipping paper. One is a rotary multi-prism punching method and equipment; and the other one is a vibrating mirror punching method and equipment. The methods and the equipment can utilize optical equipment to focus laser output by a laser; and punch pores (15) which are distributed in a single-row or multi-row curve or repeated pattern on the surface of continuously-moving tipping paper (9), such as pores (15) distributed in triangular, jagged, rhombic, trapezoidal, sine or cosine arrangement. The methods can carry out high-speed curve punching on the tipping paper, has the punching speed which is the same as linear punching speed and has good machining efficiency and good product quality; and the equipment has a simple structure, long service life, stable operation and high utilization efficiency of laser energy.

Description

Technical field [0001] The invention relates to the technical field of laser drilling, in particular to a method and equipment for laser drilling of cigarette tipping paper. Background technique [0002] It is a recognized fact that smoking is harmful to health, and reducing the tar content is of great significance to improving the health of smoking groups. Cigarette manufacturers in various countries have successively invested a lot of manpower, material resources and huge amounts of money to conduct extensive and in-depth research on the technology, theoretical methods, and practical applications of reducing cigarette tar content, and adopt a variety of scorch reduction technologies. [0003] Cigarette tipping paper is used as a special outer packaging paper for cigarette filters. It was named tipping paper because of its appearance similar to pine wood grain. The principle of filter ventilating dilution technology is to perforate tipping paper, use high-permeability filter rod...
