This device includes a sleeve connected to the abrasive roller aid wave, enabling easy adjustment and optimal setting for different fiber lengths.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the control disc is adjusted on a conventional combing machine, then the soldering process can be modified, but the fiber tips shift leading to poor yarn quality
Solution Approach 1:
The invention introduces an adjustable control disc that can be rotated to different angular positions relative to the cam disc, enabling dynamic adaptation of the soldering process to different fiber lengths and masses while maintaining consistent yarn quality through optimized phase relationships
Solution Approach 2:
The control disc can be adjusted to change the timing and duration of the soldering process, modifying parameters such as the start and end positions of the soldering action without affecting the mechanical integrity of the fiber tips, thus improving uniformity while maintaining quality
2Productivity
If the stripping rollers move to solder fiber packages, then the fiber sliver is formed, but mass fluctuations occur affecting uniformity
Solution Approach 1:
The adjustable control disc allows for optimization of the soldering timing based on the interaction between the stripping rollers and fiber packages, creating a feedback mechanism where the phase relationship can be tuned to achieve uniform mass distribution while maintaining continuous production
Solution Approach 2:
The control disc is adjusted in advance to set the optimal timing for the soldering process before production begins, ensuring that the stripping rollers are positioned correctly relative to the fiber packages to prevent mass fluctuations from the outset
3Adaptability or versatility
If the detaching roller cam disc is adjusted for different fiber lengths, then the soldering process can be optimized, but the adjustment mechanism becomes complex
Solution Approach 1:
The control disc is nested within the existing cam mechanism, rotating on the same auxiliary shaft as the cam disc. This nested arrangement allows for adjustment of the soldering process timing without adding separate complex adjustment mechanisms, maintaining simplicity while providing adaptability to different fiber lengths
