Partitioned Waste Yarn Box Layout for Suction Noise Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The noise generated by the suction operation of the suction device in a spinning device is propagated to the waste container, causing noise pollution.
Innovation Solution
A waste yarn box with a partition wall dividing the housing into an inlet and outlet chamber, where the inlet and outlet are positioned on different walls, and sound-absorbing members are used to absorb and disperse sound, reducing noise leakage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the suction device is connected to the waste container, then waste yarn can be collected, but noise is propagated to the waste container
Solution Approach 1:
The waste container is divided into multiple chambers by partition walls, separating the noise-generating suction inlet chamber from the waste storage chamber. This segmentation isolates the noise source while maintaining the waste collection function.
Solution Approach 2:
Different chambers are designed with different functions: the inlet chamber handles noisy suction operations while the outlet chamber provides a quieter waste collection space. The partition walls with ventilation holes allow air flow while blocking noise propagation.
2Object-affected harmful factors
If the housing is sealed, then noise is contained, but waste yarn cannot be collected properly
Solution Approach 1:
The housing is designed as a sealed structure to contain noise, while partition walls with ventilation holes provide controlled openings. These thin film-like partitions allow air and waste yarn to pass through while maintaining noise containment.
Solution Approach 2:
Ventilation holes in the partition walls act as intermediaries, allowing air flow and waste yarn transmission between chambers while the partition wall structure itself blocks noise propagation from the inlet chamber to the outlet chamber.
3Object-affected harmful factors
If the inlet and outlet are on opposite walls, then noise reflection is maximized, but air flow efficiency may be reduced
Solution Approach 1:
The inlet and outlet are positioned on different wall portions rather than directly opposite each other, creating a multi-dimensional air flow path through the chambers. This dimensional arrangement maximizes noise reflection while maintaining adequate air flow velocity through the ventilation holes and chamber passages.
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 noise level in the waste yarn box is significantly reduced by reflecting and absorbing sound within the box, ensuring a quieter operating environment.
Implementation Method 1
This allows the sound propagated from the suction portion to the waste yarn box to be reflected repeatedly in the waste yarn box, thereby reducing an intensity of the sound leaking from the outlet to outside of the waste yarn box.
Implementation Method 2
the suction device is connected to a compressed air pipeline for generating a suction flow, which guides the yarn into the suction device and into the godet and the bobbin

AI summary
The invention suppresses a noise. A waste yarn box includes a housing divided by a partition wall with a ventilation hole, forming two chambers: a waste yarn collection chamber and an outlet chamber. The waste yarn enters the housing configuring the waste yearn collection chamber through an inlet cylinder, while compressed air which is separated from the yarn flows out through an exhaust outlet formed in the housing configuring the outlet chamber. To enhance noise reduction, the exhaust outlet and inlet cylinder are provided on wall portions different from the left and right walls of their respective chambers. This allows a sound caused by a suction sound to be reflected repeatedly in the waste yarn box, thereby reducing an intensity of the sound leaking out of the exhaust outlet to the outside of the waste yarn box. Thus, the noise of the waste yarn box can be suppressed.
