Transversely Stiffened Conveyor Belt for Bale Press Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conveyor belts in bale presses face issues with tensioning complexity, material loss, and operational disruptions due to belt collisions and lateral instability, particularly when reduced from multiple belts to fewer, wider belts, which can lead to tipping and operational interruptions.
Innovation Solution
The integration of transverse stiffening elements within the polymer layer of the belt to enhance transverse rigidity, maintaining a stiffness ratio of at least 2:1 between transverse and longitudinal stiffness, preventing folding or bending during operation while ensuring flexibility in the longitudinal direction, thus allowing for wider belts with reduced assembly effort and improved operational reliability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the number of parallel belts is reduced to fewer, wider belts, then assembly complexity and material loss are reduced, but the belts become unstable and prone to lateral folding during operation
Solution Approach 1:
The patent applies local quality by embedding transverse stiffening elements only in specific regions of the belt where lateral stability is needed, rather than making the entire belt rigid. This allows the belt to maintain flexibility in the longitudinal direction while gaining resistance to lateral folding through localized reinforcement with stiffening elements spaced at intervals across the belt width.
Solution Approach 2:
The patent uses composite materials by combining the flexible belt material with embedded transverse stiffening elements to create a hybrid structure. This composite construction provides the necessary lateral rigidity to prevent folding while preserving the longitudinal flexibility required for belt operation, resolving the contradiction between stability and flexibility.
2Stability of the object's composition
If transverse stiffening elements are embedded in the polymer layer, then transverse rigidity is enhanced and belt folding is prevented, but the belt structure becomes more complex
Solution Approach 1:
The patent applies segmentation by dividing the stiffening function into discrete transverse stiffening elements spaced at intervals along the belt, rather than using a continuous rigid structure. This segmented approach provides adequate transverse rigidity to prevent folding while keeping the overall structure simpler and more flexible than a fully rigid belt would require.
3Stability of the object's composition
If multiple parallel belts are used, then lateral stability is maintained, but tensioning complexity and operational disruptions increase
Solution Approach 1:
The patent applies merging by consolidating multiple separate belt systems into a single wider belt with embedded stiffening elements. This combines the lateral stability function that previously required multiple parallel belts into one integrated structure, eliminating the complex tensioning mechanisms needed for multiple belts while maintaining operational reliability.
