Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing yarn coolers with multiple cooling cylinders experience irregular cooling due to varying flow rates of cooling wind, leading to inconsistent yarn quality.
Innovation Solution
The implementation of cooling cylinders with a flow control member, partitioning cylinders with a shielding member, and a quench box with a circulation space and flow adjustment plate to regulate the cooling wind flow, ensuring uniform flow rates and preventing swirl, resulting in consistent yarn quality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If multiple cooling cylinders are disposed in high density in one quench box, then the efficiency in producing yarns is improved, but the flow rate of cooling wind supplied to each yarn running space becomes significantly different, causing irregular cooling and yarn quality variation
Solution Approach 1:
The invention divides the cooling wind supply system into separate circulation spaces for each cooling cylinder, with individual flow adjustment plates. This segmentation allows independent control of cooling wind flow to each cylinder, enabling high-density arrangement while maintaining uniform cooling across all cylinders and preventing yarn quality variation.
2Productivity
If cooling cylinders are arranged in high density, then the number of ducts is reduced and productivity improves, but the cooling wind flow varies significantly in the circumferential direction of each cylinder, causing swirl and irregular cooling
Solution Approach 1:
The invention introduces flow adjustment plates in the circulation spaces of cooling cylinders that are positioned at locations corresponding to spinnerets with potentially higher cooling demand. This local adjustment compensates for circumferential flow variations, ensuring stable and uniform cooling wind supply to all yarn running spaces regardless of cylinder position in the high-density arrangement.
3Device complexity
If one quench box is provided for multiple cooling cylinders, then the number of ducts is reduced, but the flow of cooling wind around each cylinder becomes significantly different, leading to inconsistent cooling performance
Solution Approach 1:
The invention introduces circulation spaces as intermediary regions between the common quench box and individual cooling cylinders. Each circulation space is equipped with a flow adjustment plate that acts as a mediator to regulate and equalize the cooling wind flow before it enters each cooling cylinder, ensuring consistent cooling performance while maintaining a simplified single-quench-box structure.

AI summary
The qualities of yarns are uniformized. For each of cooling cylinders 30, a partition 51 is provided to surround each cooling cylinder 30 and form a circulation space 52 between the partition 51 and the outer circumferential surface of the cooling cylinder 30 to allow cooling wind to circulate in the circulation space 52, and at a border part between a supply space 23 to which the cooling wind is supplied from the outside and the circulation space 52, a flow adjustment plate 53 is provided to circulate the cooling wind from the supply space 23 into the circulation space 52 while adjusting the flow of the cooling wind.
