Interchangeable Suction Channel End Part for Fiber Fly Removal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing suction channel end parts for drafting systems are not cost-effective and lack flexibility in adapting to different fiber types, requiring complex adjustments or replacements to optimize fiber fly removal.
Innovation Solution
A multi-part suction channel end part design with interchangeable components, including a first component and a cover element, allows for easy adaptation to different fiber types by replacing the second component, which has variable suction openings, and can be fixed using positive-locking or friction-locking means, with optional funnels for improved suction, manufactured via 3D printing, laser sintering, or plastic injection molding.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a single, larger suction opening is used, then fiber fly removal efficiency is improved, but adaptability to different fiber types deteriorates
Solution Approach 1:
The suction channel end part is divided into multiple separate suction openings instead of a single large opening. Each suction opening can be independently adjusted or removed, allowing the system to adapt to different fiber types while maintaining effective fiber fly removal through the combined action of multiple openings.
2Adaptability or versatility
If the distance between suction openings is adjusted for different fiber types, then adaptability is improved, but device complexity increases
Solution Approach 1:
The suction openings are designed to be movable along the suction channel, allowing their positions to be dynamically adjusted depending on the fiber type being processed. This dynamic positioning capability enables adaptability without requiring complex fixed adjustment mechanisms, as the openings can be freely repositioned along the channel length.
3Adaptability or versatility
If multiple adjustable suction openings are provided, then adaptability to different fiber types is improved, but manufacturing cost increases
Solution Approach 1:
Instead of providing multiple fully adjustable suction openings with complex mechanisms, the invention uses a simplified approach where suction openings can be freely positioned along the channel without individual adjustment mechanisms for each opening. This partial adjustment capability achieves the needed adaptability while significantly reducing manufacturing complexity and cost.

AI summary
The present invention relates to a suction duct end section (1) for removing fiber debris in the area of a drafting unit by means of applying a vacuum, wherein the suction duct end section (1) comprises a vacuum-operated first component (2) with an inlet (21) and an outlet (22) communicating with the inlet (21). The suction duct end section (1) is characterized in that it has a vacuum-operated second component (3) designed as a cover element, which is interchangeably connectable to the first component (2). The second component (3) has an opening (33) which, in the assembled state of the suction duct end section (1), forms a suction opening communicating with the inlet (21), through which the fiber debris can be removed when a vacuum is applied to the suction duct end section (1).
