Cleaning Implement Production Using Continuous Drum-Roll Bonding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing method for manufacturing cleaning tools with cleaning sheets and holders faces challenges in achieving high-speed production due to the need for temporary stopping of superposed materials during the bonding process.
Innovation Solution
A method and device that involves feeding band-like elements, superposing them, and using a bonding device with a drum roller and bonding section to form bonded regions continuously, allowing for high-speed production without temporary stops.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the superposed materials are temporarily stopped during bonding, then the bonding quality is improved, but the production speed deteriorates
Solution Approach 1:
The patent implements continuous conveyance of the band-like elements through the bonding device without temporary stops. The drum roller continuously rotates to convey the materials through the bonding section, eliminating idle time while maintaining bonding quality through controlled residence time in the bonding zone.
Solution Approach 2:
The patent employs a dynamic bonding system where the drum roller rotates at controlled speeds to convey materials through the bonding section. The rotational speed of the drum roller is adjusted to optimize both bonding quality and production throughput, transforming the static temporary-stop approach into a dynamic continuous process.
2Reliability
If multiple bonded regions are formed, then the bonding reliability is improved, but the device complexity increases
Solution Approach 1:
The patent divides the bonding process into multiple bonded regions (first bonded region and second bonded region) along the conveyance direction. Each region is formed by the drum roller and bonding section at different positions, allowing distributed bonding that improves reliability without requiring complex multi-device configurations.
Solution Approach 2:
The single drum roller and bonding section perform multiple functions by forming both the first bonded region and the second bonded region. This multi-functional design achieves enhanced bonding reliability through multiple bonding zones while avoiding the device complexity increase that would result from using separate bonding devices for each region.
