Yarn Spinning Slow-Cooling Structure With Adjustable Cooling Space
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The increasing number of yarns spun out from a spinning apparatus requires a complex arrangement of upper and lower hoods, leading to increased component count and costs, and the need to adjust the slow cooling space length in the up-down direction without introducing outside air.
Innovation Solution
A yarn spinning system with a block member and adjustment unit that allows for changing the length of the slow cooling space by adjusting the relative positions of the block member and cooling cylinders, using a sealing member to prevent outside air intrusion and a movement mechanism for easy operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If upper hood and lower hood are provided for each yarn to enable slow cooling space adjustment, then the slow cooling space can be adjusted for different yarn types, but the number of components increases and cost increases
Solution Approach 1:
The patent merges the functions of multiple hoods into a single block member that can surround multiple cooling cylinders. This block member integrates the slow cooling space formation for all yarns simultaneously, eliminating the need for separate upper and lower hoods for each yarn while maintaining the ability to adjust the slow cooling space length for different yarn types and specifications.
Solution Approach 2:
The block member is designed as a universal component that can adapt to different yarn configurations and cooling requirements. By making the block member movable in the up-down direction and adjustable in position, it serves multiple functions: forming slow cooling spaces for multiple yarns, enabling adjustment for different yarn types, and reducing the overall component count while maintaining versatility.
2Adaptability or versatility
If the cooling apparatus is fixed to maintain slow cooling space length, then structural stability is maintained, but adjustment for different yarn types is not possible
Solution Approach 1:
The block member is designed to be movable in the up-down direction, transforming the static structure into a dynamic one. This allows the slow cooling space length to be adjusted according to different yarn types, filament thicknesses, and production requirements while maintaining structural stability through controlled movement and proper mechanical design of the support and adjustment mechanisms.
3Ease of repair
If block member and cooling cylinders are fixed in relative position, then alignment is maintained, but maintenance and adjustment require realignment which increases time and complexity
Solution Approach 1:
The system is segmented into independently movable components: the block member can move relative to the cooling cylinders, and the cooling apparatus can move independently. This segmentation allows maintenance personnel to access and service individual components without requiring realignment of the entire assembly, significantly reducing maintenance time and complexity while maintaining proper alignment through designed movement paths and positioning mechanisms.
