Adjustable Seed Roll Retaining Member for Gin Saw Stand
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current gin saw stands face issues with seed roll breakage and loss of un-ginned seeds due to increased capacities and density, leading to cumbersome and rigid roll box doors that require manual effort to open, resulting in inefficient seed separation and higher operational costs.
Innovation Solution
A novel gin saw stand with a powered roll box door and an adjustable seed roll retaining member that allows for reconfiguration of the roll box shape during operation, enabling the seed roll to be automatically extended for support when the breast is opened, reducing seed roll breakage and improving seed separation efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the roll box door is made rigid and heavy to maintain structural integrity, then the strength is improved, but the ease of operation deteriorates as it requires manual effort to open
Solution Approach 1:
The patent replaces the manual mechanical operation of the roll box door with an automated powered system. A motor (365) connected through a gear mechanism (364, 363) automatically opens and closes the roll box door (36), eliminating the need for manual effort while maintaining the door's structural integrity through its rigid construction.
2Productivity
If the gin saw stand capacity is increased to handle more cotton, then the productivity is improved, but the seed roll stability deteriorates leading to breakage and seed loss
Solution Approach 1:
The patent introduces a dynamic adjustable sheet member (20) that can move vertically along the roll box wall to adapt to different seed roll sizes and densities. This member is positioned by a cam shaft assembly (48) that allows adjustment during operation, enabling the system to maintain seed roll stability even when handling increased cotton capacities and denser seed rolls.
Solution Approach 2:
The patent changes the physical parameters of the roll box configuration by introducing an adjustable sheet member that modifies the roll box shape. This member can be positioned at different heights and angles to accommodate varying seed roll densities and sizes, thereby maintaining optimal seed roll stability across different operating conditions and productivity levels.
3Device complexity
If the roll box shape is fixed to simplify the structure, then the device complexity is reduced, but the adaptability deteriorates as it cannot adjust to different seed roll configurations
Solution Approach 1:
The patent transforms the static roll box structure into a dynamic system by incorporating an adjustable sheet member (20) that can change position during operation. This member is controlled by a cam shaft assembly (48) with multiple positions, allowing the roll box shape to adapt to different seed roll configurations while adding only moderate complexity to the overall structure.

AI summary
A saw type gin stand for separating cotton lint from seed cotton in which the improvement comprises one or more of the inwardly facing surfaces of the roll box being movably adapted to re-shape the roll box. Specifically the inner surface of the roll box door member and a seed roll retaining member are adjustable during operation of the gin to re-shape the shape of the gin to optimize performance and, when the breast is opened, to retain the seed roll within the roll box and prevent pieces of the seed roll from breaking off of the roll.
