Segmented Conveyor Belt Guide Fingers Nonwoven Web Transport
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The transport of high-volume nonwoven webs in textile processing machines often results in mechanical deformation and distortion due to the voluminous web rising between transport elements, leading to jams and loss of desired product properties, especially when transitioning from a crosslapper to a needling machine.
Innovation Solution
A feed system comprising a circulating conveyor belt with multiple belt strips and guide fingers, which gently guides the fleece belt close to the bonding zone, using a cover belt or roller as a secondary transport device to prevent mechanical deformation and ensure safe transport over longer distances.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a conventional transport system with single belt is used, then the structure is simple, but the voluminous nonwoven web rises between transport elements causing mechanical deformation and distortion
Solution Approach 1:
The transport system is segmented into multiple belt strips (first belt strip, second belt strip) arranged parallel to each other, with the nonwoven web positioned between them. This segmentation prevents the web from rising between single transport elements by providing continuous side support, thereby eliminating mechanical deformation while maintaining structural simplicity.
Solution Approach 2:
Guide fingers are introduced as intermediary elements between the belt strips and the nonwoven web. These guide fingers gently guide the web along the transport path, preventing lateral displacement and mechanical deformation without requiring complex transport mechanisms.
2Reliability
If the distance between nonwoven section and consolidation field is large, then transport is safer, but fiber structures are lost on the way to consolidation
Solution Approach 1:
The transport system uses multiple belt strips arranged parallel to each other, creating a confined transport path that prevents the voluminous nonwoven web from rising between transport elements. This segmented approach enables safe transport over longer distances without mechanical deformation, allowing the web to reach the consolidation field intact while maintaining fiber structure.
3Stability of the object's composition
If the conveyor belt is in contact with the nonwoven web, then transport is stable, but mechanical pressure causes distortion of the web
Solution Approach 1:
The conveyor belt is segmented into multiple parallel belt strips rather than a single continuous belt. This segmentation allows the web to be transported between the strips without direct pressure from a single belt surface, maintaining web stability while preventing distortion through distributed contact points.
Solution Approach 2:
Guide fingers serve as intermediary elements between the belt strips and the nonwoven web. These fingers provide gentle guidance and lateral support to the web during transport, ensuring stable positioning without applying mechanical pressure that would cause distortion.
