Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional splicers fail to effectively splice relatively elastic yarns like wool, resulting in insufficient yarn tenacity and potentially leaving whisker-like splicing portions that affect the yarn's appearance.
Innovation Solution
A splicer nozzle with divided yarn splicing chambers and linear compressed air injection holes that communicate with a common slit, where the air injection holes are orthogonal to the chamber walls, allowing compressed air to directly strike and entangle yarn ends, preventing whirling streams and enhancing tenacity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the opposite type splicer is used to splice thin, nonelastic yarns, then the yarn ends can be twisted and spliced, but it fails to sufficiently twist elastic yarns resulting in insufficient yarn tenacity
Solution Approach 1:
The yarn splicing hole is divided into substantially two yarn splicing chambers formed at positions where axes of the yarn splicing chambers are displaced from each other. This segmentation allows compressed air to be injected from multiple directions, creating a more effective twisting action that can handle both thin nonelastic yarns and elastic yarns, thereby improving yarn tenacity while maintaining versatility.
Solution Approach 2:
The invention introduces a multi-dimensional approach by displacing the axes of the two yarn splicing chambers from each other and injecting compressed air from different spatial positions. This dimensional change in the air injection system creates a more comprehensive twisting effect that effectively processes elastic yarns while maintaining effectiveness for nonelastic yarns.
2Strength
If the T-type splicer is used to firmly entangle elastic yarns, then sufficient yarn tenacity can be obtained, but whisker-like splicing portions remain affecting the yarn appearance
Solution Approach 1:
By dividing the yarn splicing hole into two separate chambers with displaced axes, the invention creates a more distributed entanglement pattern. This segmentation prevents the concentration of splicing portions in a single location, thereby eliminating the whisker effect while maintaining firm entanglement and sufficient yarn tenacity.
Solution Approach 2:
The invention employs asymmetric positioning of the two yarn splicing chambers with displaced axes, creating an asymmetric air injection pattern. This asymmetry distributes the splicing action across different locations, preventing the formation of concentrated whisker-like portions and improving the overall appearance of the spliced yarn.
3Device complexity
If compressed air is injected through a single hole into a single chamber, then the structure is simple, but the air cannot directly strike yarn ends positioned in a common slit resulting in weak entanglement
Solution Approach 1:
The invention segments the air injection system into multiple injection holes, each communicating with a separate yarn splicing chamber. This segmentation allows compressed air to directly strike yarn ends positioned in the common slit from multiple angles, creating strong entanglement. The segmented design achieves effective yarn entanglement while maintaining reasonable structural complexity.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The splicer nozzle ensures strong entanglement of yarn fibers, eliminating whiskers and improving the tenacity of spliced portions, particularly for elastic yarns like wool.
Implementation Method 1
compressed air passing through the yarn splicing slit to the axis of the yarn splicing chamber is injected through a corresponding one of the injection holes
Implementation Method 2
compressed air collides against and bounces off the inner wall and strikes the yarn ends again
