Mineral Wool Roller Table for Uniform Fiber Distribution
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mineral wool production facilities face challenges in achieving uniform distribution and optimal thermal insulation performance due to clumping of fibers, leading to uneven fiber arrangement and reduced insulation efficiency.
Innovation Solution
A facility with a roller table system on the conveyor belt, featuring multiple rollers that can rotate independently to distribute mineral fibers uniformly through the thickness of the fiber mat, eliminating the need for suction means and using mechanical guidance to direct fibers onto the conveyor belt, ensuring uniform distribution and longitudinal orientation of fibers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If suction means are used to distribute fibers, then fiber distribution is achieved, but device complexity increases and control precision decreases
Solution Approach 1:
The invention removes suction means from the distribution station, extracting the problematic aeraulic components while maintaining fiber distribution functionality through simpler mechanical means. The distribution station no longer includes suction chambers or blowers, eliminating the complexity associated with aeraulic control systems.
Solution Approach 2:
The invention replaces the aeraulic distribution system with a mechanical roller table system. Rollers mechanically guide and distribute fibers onto the conveyor belt through direct contact, substituting the previous air-based distribution mechanism with a simpler mechanical approach that provides better control and uniformity.
2Manufacturing precision
If rollers are positioned close to conveyor belt, then fiber orientation control improves, but fiber clumping increases
Solution Approach 1:
The roller table is divided into multiple independently controllable rollers arranged in sequence. This segmentation allows different rollers to perform different functions: earlier rollers handle fiber guidance and separation, while later rollers focus on orientation. The segmented approach prevents any single roller from creating clumps while collectively achieving uniform distribution and proper orientation.
Solution Approach 2:
The invention makes the roller table dynamic by allowing independent speed control of each roller. This dynamic adjustment capability enables optimization of fiber flow at different positions, preventing clumping at the entry point while ensuring proper orientation at the deposition point. The dynamic system adapts to varying fiber conditions to maintain both uniformity and orientation.
