Double Folding Leaves Device Using Conveyor Belt Dynamics
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing devices for double folding leaves are inefficient, requiring manual insertion, positioning, and removal of leaves, resulting in low production speed and the need for multiple machines to achieve acceptable quantities, with most devices unable to double fold leaves in less than three seconds.
Innovation Solution
A device featuring two conveyor belts that guide leaves through folding elements, allowing for simultaneous double folding without successive operations, using pre-folders and folders to create a sharp fold line and unfolding elements to reset the strip for seamless folding across the leaf, enabling high-speed production.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual insertion, positioning, and removal of leaves is used, then the device structure is simple, but the production speed is low and time consumption is high
Solution Approach 1:
The patent applies the dynamics principle by replacing static manual operations with a dynamic conveyor belt system. The conveyor belts automatically transport leaves through the folding mechanism, enabling continuous high-speed processing without manual intervention. This dynamic automation resolves the contradiction by significantly increasing production speed while maintaining manageable device complexity through the use of standardized conveyor components.
Solution Approach 2:
The patent implements self-service by designing a system where the conveyor belts automatically feed, position, and remove leaves without human assistance. The leaves are automatically guided through the folding elements and the folded leaves are automatically collected. This self-automating mechanism eliminates manual labor bottlenecks and achieves high productivity with a relatively simple overall device structure.
2Productivity
If successive folding operations are performed, then the folding precision can be controlled, but the processing time increases and production efficiency decreases
Solution Approach 1:
The patent applies segmentation by dividing the folding process into distinct sequential stages using multiple folding elements. Each folding element performs a specific folding action on different portions of the leaf, allowing simultaneous multi-point folding. This segmented approach enables high-speed processing while maintaining precision through controlled sequential activation of each folding element.
Solution Approach 2:
The patent transitions from sequential one-dimensional folding to parallel multi-dimensional folding by positioning multiple folding elements along the conveyor path. Leaves are folded at multiple locations simultaneously as they move through the device, effectively adding a spatial dimension to the folding process. This enables high-speed production without sacrificing folding precision through the coordinated action of distributed folding elements.
3Productivity
If leaves are processed one by one, then positioning accuracy is high, but the production quantity per hour is limited
Solution Approach 1:
The patent implements continuous useful action through the conveyor belt system that continuously feeds, processes, and removes leaves without interruption. Multiple folding elements operate simultaneously on different leaves in sequence, maintaining continuous high-speed processing. This continuous operation achieves high production quantities while the conveyor belt's consistent movement ensures adequate positioning accuracy without requiring manual intervention for each leaf.
