Conveyor Belt Junction Plates With Run-Proof Textile Reinforcement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conveyor belt junction devices face challenges in maintaining resistance to wear and tear, particularly due to unweaving of textile reinforcements under tensile forces, which affects their durability and efficiency in connecting conveyor belt ends.
Innovation Solution
Incorporating an unweaving reinforcement with a filler wire and/or blocking wire along the transverse edges of the junction plates, which prevents unweaving and enhances resistance to tensile forces by ensuring a homogeneous distribution of stress across the reinforcement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the junction device uses textile reinforcement to connect conveyor belt ends, then it provides flexibility and extensibility to withstand tensile forces, but the reinforcement suffers from unweaving and premature combing under significant tensile forces, reducing durability
Solution Approach 1:
The patent combines textile reinforcement with a filler wire (metal or synthetic) to create a composite structure. The filler wire is integrated into the textile reinforcement along the transverse edges, forming a hybrid material system that leverages both the flexibility of textile and the structural stability of the filler wire to prevent unweaving while maintaining tensile strength
Solution Approach 2:
The filler wire is strategically positioned only along the transverse edges of the reinforcement where unweaving occurs, rather than throughout the entire reinforcement. This localized application provides run-proofing precisely where needed while preserving the overall flexibility and extensibility of the junction device
2Ease of operation
If the junction device uses traditional textile reinforcement without filler wire, then it maintains flexibility and extensibility for crossing curves, but the transverse edges are prone to unweaving under tensile forces
Solution Approach 1:
The patent creates a composite structure by integrating a filler wire into the textile reinforcement along the transverse edges. This composite design maintains the flexibility and extensibility of the textile material needed for crossing curves while the filler wire provides structural stability to prevent edge unweaving
Solution Approach 2:
The filler wire is applied locally only at the transverse edges where unweaving occurs, rather than throughout the entire reinforcement. This localized reinforcement preserves the overall flexibility and extensibility of the junction device while providing targeted stability where needed
