Laser Perforating Machine for Double Filter Cigarettes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing laser perforating machines are unable to form perforations that tilt towards the axis of a double filter cigarette, as they typically intersect orthogonally, making it difficult to create the required tilting perforations for new types of filter cigarettes that release mainstream smoke into the user's mouth.
Innovation Solution
A laser perforating machine with a simple structure that converges laser beams from left and right emitting ports to form perforations tilting towards the axis of the double filter cigarette, using converging lenses and angle setting mirrors to adjust the beam direction, allowing for precise placement of perforations within a range of less than 10 mm from the cutting position.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If laser beams are radiated orthogonally to the axis of the double filter cigarette from left and right emitting ports, then the manufacturing process is simple and efficient, but it is impossible to form perforations that tilt towards the axis of the filter cigarette
Solution Approach 1:
Instead of radiating laser beams orthogonally from left and right ports, the invention radiates beams from front and right ports at angled intersections, inverting the traditional orthogonal radiation approach to achieve tilted perforations
Solution Approach 2:
The invention changes the radiation parameters by positioning emitting ports at different locations (front and right sides) and radiating laser beams at different angles to intersect at specific points, thereby controlling the tilt angle of perforations without increasing device complexity
2Measurement precision
If laser beams are radiated from multiple emitting ports at different positions, then perforations can be formed at precise locations within 10 mm of the cutting position, but the device structure becomes more complex
Solution Approach 1:
The laser generator serves multiple functions by radiating beams through different optical paths to multiple emitting ports, allowing a single device to achieve precise perforation placement at various locations without requiring separate laser sources for each position
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The machine effectively forms perforations that tilt towards the axis of each filter cigarette, enhancing the smoking experience by allowing mainstream smoke to be released into the user's mouth, while maintaining a compact design and preventing optical path interference.
Implementation Method 1
the laser perforating machine has a left laser-beam emitting port allowing a laser beam to emit therefrom, the left laser-beam emitting port being located on a left part side of the double filter leftward of the cutting position so as to radiate the laser beam to the left part of the double filter
Implementation Method 2
the laser perforating machine radiates two or more laser beams through the double tipping paper to the double filter, and each laser beam forms vent holes for each of the filter cigarettes

AI summary
A laser perforating machine (10) of the present invention has: a left-sided laser-beam radiating unit (28) that converges a branched laser beam (BL) onto a right part (16R) of a double filter (16) from a left laser-beam emitting port (24) located on a left part (16L) side of the double filter (16), thereby forming perforations (H) tilting to an axis of a double filter cigarette (12) into the right part (16R); and a right-sided laser-beam radiating unit (30) that converges a branched laser beam (BR) onto a left part (16L) of the double filter (16) from a right laser-beam emitting port (26) located on a right part (16R) side of the double filter cigarette (12), thereby forming perforations (H) tilting to the axis into the left part (16L), when the double filter cigarette (12) is located at a perforating position (PP) defined on a perforating drum (20).
