Air Spinning Device Nozzle Cap Attachment Precision
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Air spinning devices face variations in spun yarn twisting firmness due to changes in the shape of the spinning chamber caused by shifting attachment positions of the fiber guide and nozzle block, and the devices' inability to easily adapt to different fiber characteristics, leading to inconsistent yarn quality.
Innovation Solution
An air spinning device with a fiber guide, nozzle block, spindle, and nozzle holder configuration that allows for precise attachment and easy replacement of components, using a nozzle cap to fix the fiber guide and nozzle block to the nozzle holder, and a detachable nozzle holder design that supports easy adjustment and replacement based on fiber characteristics.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the fiber guide and nozzle block are fixed to the spinning chamber, then the spinning chamber shape is defined, but variations in attachment positions cause variations in spinning chamber shape and twisting firmness
Solution Approach 1:
A positioning plate is introduced as an intermediary component between the fiber guide/nozzle block and the spinning chamber. The positioning plate has pre-formed positioning holes that ensure precise and consistent attachment positions of the fiber guide and nozzle block, thereby maintaining consistent spinning chamber shape and twisting firmness across different installations.
Solution Approach 2:
The positioning plate allows for adjustable positioning of the fiber guide and nozzle block by providing multiple positioning holes at different locations. This enables optimization of the attachment positions to achieve the desired spinning chamber shape and twisting firmness for different fiber characteristics.
2Adaptability or versatility
If the fiber guide and nozzle block are permanently fixed, then attachment precision is maintained, but replacement and adjustment for different fiber characteristics become difficult
Solution Approach 1:
The attachment system is segmented into separable components: the positioning plate with positioning holes, the fiber guide, the nozzle block, and the spinning chamber. This segmentation allows the fiber guide and nozzle block to be easily detached and reattached at different positions by simply aligning them with the positioning holes, enabling quick adaptation to different fiber characteristics without complex manufacturing or permanent fixation.
3Reliability
If the attachment positions are not precisely controlled, then component replacement is easy, but the spinning chamber shape varies leading to inconsistent yarn quality
Solution Approach 1:
The positioning plate serves as a simple intermediary device that provides pre-formed positioning holes to ensure precise attachment positions. This simple structure effectively controls the positions of the fiber guide and nozzle block without introducing complex adjustment mechanisms, thereby maintaining yarn quality consistency while avoiding excessive device complexity.
