Cigarette Filter Cleaning Device for Carbon Particle Removal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing methods for manufacturing cigarettes with filtering parts containing cellulose acetate fibers and active carbon particles often result in unsatisfactory quality and connection issues, leading to around 10% of produced cigarettes being discarded.
Innovation Solution
A machine and method that incorporates a cleaning device to detach and remove loose active carbon particles from cellulose acetate fibers before wrapping, and a coupling device to securely bind the filtering and active parts, using a conveying system to improve the quality and consistency of the smoking articles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If loose particles are present in the filtering portion, then the filtering material can be easily applied, but the quality of the smoking article deteriorates due to particle interference during wrapping
Solution Approach 1:
The cleaning device removes loose particles from the filtering portion before the wrapping operation occurs. This preliminary cleaning action prevents particles from interfering with the wrapping process and ensures high-quality finished products while maintaining ease of manufacturing
2Device complexity
If loose particles remain on the filtering portion, then the production process is simpler, but the connection between filter and active part becomes unreliable
Solution Approach 1:
The cleaning device performs particle removal as a preliminary step before wrapping and coupling operations. This ensures that loose particles do not interfere with the connection between the filter and active part, maintaining reliability without significantly complicating the production process
3Productivity
If no cleaning step is implemented, then the production speed is higher, but the number of defective cigarettes increases
Solution Approach 1:
The cleaning device removes particles before wrapping, preventing defects that would require discarding cigarettes. This preliminary cleaning action reduces waste and improves overall productivity by ensuring higher quality output without significantly slowing down the production line
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
This approach enhances the quality of smoking articles by reducing particle interference during wrapping and improves the connection between filtering and active parts, thereby reducing the number of defective cigarettes.
Implementation Method 1
a cleaning device (10), which is arranged in the area of a cleaning station (11) and is designed to force at least part of the particles (7) to detach themselves from the first material (6) and be removed from the first material (6) itself
