Roller Conveying Rack Linkage for Quick Width Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current roller conveying lines with adjustable width require multiple adjustments of individual rollers and frame components, leading to complexity, increased manufacturing costs, and difficulty in maintenance due to repetitive operations.
Innovation Solution
A roller conveying rack design featuring parallel carrier plates connected by sleeve and movable shafts, with rotating shafts driven by servo motors, allowing for quick width adjustments through synchronized linkage of multiple rollers via insertion holes and threaded bolts, and utilizing ball sliding sleeves to reduce friction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple independent rollers and frame adjustment portions are provided to achieve adjustable width, then the conveying line can accommodate different product widths, but the structure becomes complicated and adjustment operations become repetitive
Solution Approach 1:
The patent combines multiple independent rollers into a linked assembly where adjacent rollers are connected through shared frame adjustment portions. This merging reduces the total number of independent components while maintaining the ability to adjust width across the entire conveying line, thereby reducing structural complexity while preserving adaptability.
Solution Approach 2:
The frame adjustment portion serves multiple functions: it connects adjacent rollers, enables width adjustment, and provides structural support. This multi-functionality eliminates the need for separate adjustment mechanisms for each roller, simplifying the overall structure while maintaining adjustable width capability.
2Adaptability or versatility
If each roller and frame adjustment portion is independently adjusted to change conveying line width, then the width can be customized, but the adjustment speed decreases due to repetitive operations
Solution Approach 1:
By linking adjacent rollers through shared frame adjustment portions, the patent enables synchronized adjustment of multiple rollers simultaneously. This merging allows the entire conveying line width to be adjusted in a single operation rather than requiring independent adjustment of each roller, thereby increasing adjustment speed while maintaining customization capability.
3Adaptability or versatility
If multiple frame adjustment portions are provided for width adjustment, then the conveying line can be customized for different widths, but maintenance difficulty increases due to repetitive components
Solution Approach 1:
The patent merges multiple frame adjustment portions into a standardized modular assembly that can be replicated. This standardization reduces the variety of components that need maintenance, as failures can be addressed using the same adjustment mechanism across all rollers, thereby reducing maintenance difficulty while preserving width customization capability.
4Adaptability or versatility
If individual rollers are adjusted independently to achieve width changes, then the conveying line can be adapted to different products, but manufacturing cost increases due to repeated adjustment mechanisms
Solution Approach 1:
The patent combines multiple independent adjustment mechanisms into a single standardized frame adjustment portion that serves multiple rollers. This reduction in the number of unique components simplifies manufacturing processes and reduces material requirements, thereby lowering manufacturing costs while maintaining the ability to adapt to different product widths.
