Fiber Processing Working Element Ejection Distance Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fiber-processing machines with working elements and separating knives face challenges in adjusting the ejection distance efficiently, leading to time-consuming processes and reduced accuracy due to complex constructions and multiple adjusting screws.
Innovation Solution
A working element with a carrier that supports a receptacle for a closure element, allowing for simple adjustment of the ejection distance by inserting a closure element that generates a clamping force, enabling independent adjustment without altering the knife blade's setting relative to the roller.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If multiple adjusting screws are used to adjust the ejection distance, then the adjustment can be made, but the adjustment process becomes time-consuming and complex
Solution Approach 1:
The working element is divided into modular components: a carrier element with a receptacle and a separate closure element. The closure element can be independently attached to the carrier element, allowing for simple, tool-free adjustment of the ejection distance without requiring multiple adjusting screws.
Solution Approach 2:
The closure element is designed to be detachably attachable to the carrier element, enabling dynamic adjustment of the ejection distance. This allows the operator to quickly change the closure element to adjust the ejection distance without time-consuming operations.
2Ease of operation
If adjusting screws are made freely accessible, then accessibility is improved, but the adjustment still requires multiple screws and time-consuming operations
Solution Approach 1:
The adjustment mechanism is segmented into a carrier element and a separate closure element. This segmentation eliminates the need for multiple adjusting screws and complex adjustment mechanisms, while maintaining free accessibility for attaching or detaching the closure element.
Solution Approach 2:
The closure element is extracted as a separate, independently attachable component from the carrier element. This extraction simplifies the adjustment mechanism by removing the need for multiple adjusting screws and complex adjustment systems.
3Adaptability or versatility
If a movable guide element is used to change ejection width, then adjustability is achieved, but dimensional stability is compromised and unwanted adjustment during operation occurs
Solution Approach 1:
The closure element is designed with detachable attachment to the carrier element, providing dynamic adjustability of the ejection width. When attached, it ensures stable positioning without unwanted movement during operation, combining both adaptability and dimensional stability.
4Adaptability or versatility
If the knife blade and guide element are located on different cleaning elements, then flexibility is improved, but adjustment accuracy is reduced due to independent attachment
Solution Approach 1:
The knife blade and closure element are combined on the same carrier element. This merging ensures that both components are positioned relative to each other with high precision, eliminating errors caused by independent attachment while maintaining the flexibility of the modular carrier element design.

AI summary
The invention relates to a working element (10, 11, 12) on a fibre-processing machine having at least one roller (3, 13), wherein the working element (10, 11, 12) is arranged at a distance (a) opposite the roller (3, 13). The working element extends over the entire working width of the roller (3, 13), wherein part of the working element (10, 11, 12) is formed as an extraction channel (25). The working element (10, 11, 12) has at least one scraping blade (20) and a further carding element (21) or covering element (29). An opening (26) having an ejection width (c) is located between the scraping blade (20) and the carding element (21) or covering element (29). The opening (26) connects a space between the working element (10, 11, 12) and roller (3, 13) to the extraction channel (25). The working element (10, 11, 12) has a receptacle in which a closure element (27) is held in a fixed position with the aid of a clamping force, wherein the ejection width (c) is provided by the shape of the closure element (27).
