Segmented Carding Machine Cover With Ring Fastening
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods for attaching inner linings to carding machines are complex and costly due to the use of numerous individual parts and brackets, making assembly and maintenance cumbersome.
Innovation Solution
A carding machine with a ring-shaped fastening device that extends around the axis of rotation of the drum, allowing for a demountable and flexible casing system composed of multiple surface segments, which can be easily assembled and disassembled, and features a design that minimizes interference with adjacent machine elements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional attachment methods using numerous individual parts and brackets are used to attach inner linings to side plates, then the shielding and sealing function is achieved, but the assembly complexity and cost increase significantly
Solution Approach 1:
The patent combines multiple individual fastening parts and brackets into a single integrated ring-shaped fastening device that attaches to the side plate and secures the inner lining. This merging of multiple components into one unified structure reduces assembly complexity while maintaining the shielding and sealing functions.
Solution Approach 2:
The ring-shaped fastening device serves multiple functions simultaneously: it attaches the inner lining to the side plate, provides structural support, and maintains the shielding and sealing functions. This multi-functionality eliminates the need for separate brackets and fastening elements.
2Reliability
If conventional casing systems with larger dimensions are used, then complete shielding is achieved, but handling during maintenance becomes difficult
Solution Approach 1:
The inner lining is divided into multiple segments that can be independently removed and handled. This segmentation allows maintenance personnel to access and replace only the specific segment that needs maintenance, rather than handling the entire large-dimensional casing system.
3Strength
If numerous individual parts are used for attachment, then secure fastening is achieved, but the number of parts to be managed increases
Solution Approach 1:
The patent merges multiple individual fastening parts into a single ring-shaped fastening device that provides secure attachment of the inner lining to the side plate. This reduces the quantity of parts from numerous individual components to one integrated structure.

AI summary
The invention relates to a carding machine (1) for the production of nonwoven fabric from fibrous material, comprising at least one cylinder (2a; 2b), which is mounted about an axis of rotation, side shields arranged on either side of the cylinder (2a; 2b) and fixedly mounted on a rack (3), and at least one cover (V1; V2), which is arranged to the side of the cylinder (2a; 2b). The cover (V1; V2) is connected to an allocated side shield by means of a fastening device (B), particularly one consisting of metal, wherein the fastening device (B) has an annular shape in such a manner that said device extends at least along an annular portion about the axis of rotation of the cylinder (2a; 2b). Furthermore, the cover (V1; V2) consists of a plurality of planar segments which are arranged in a ring around the axis of rotation of the cylinder (2a; 2b).
