Smoothing Plant Frame Segmentation for Heavy-Roller Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing calender systems face challenges in providing easy and safe access for maintenance and replacement of large, heavy rollers, particularly in multi-roller arrangements, often requiring complex mechanisms or separate devices that complicate accessibility and weaken the construction.
Innovation Solution
The machine frame is divided into two parts, allowing movement in horizontal and perpendicular directions using existing drive mechanisms, with a positive-locking hook connection for easy detachment and reconnection, enabling rollers to be safely moved into a parked position without additional components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a single integrated machine frame is used, then structural strength and stability are maintained, but accessibility for roller maintenance and replacement is poor
Solution Approach 1:
The machine frame is divided into two separate parts: a first part and a second part. The second part can be detached from the first part using coupling means, allowing the roller to be accessed and removed from the second part without compromising the overall structural integrity when coupled. This segmentation enables maintenance personnel to access the roller easily while maintaining structural strength during operation.
2Adaptability or versatility
If complex carriage mechanisms with hydraulic cylinders are used to move rollers, then roller positioning capability is improved, but device complexity and manufacturing cost increase
Solution Approach 1:
The second part of the machine frame, which contains the roller, is designed to be movable relative to the first part. The coupling means allow for easy attachment and detachment, providing dynamic reconfigurability. This enables the roller to be positioned in different locations (such as a parked position at the edge of the machine frame) without requiring complex hydraulic cylinders and lever arms, thus reducing device complexity while maintaining positioning capability.
3Ease of operation
If the machine frame is divided into separate parts, then accessibility for roller maintenance is improved, but the stability of the machine frame composition deteriorates
Solution Approach 1:
The machine frame is divided into two separate parts that can be detached and reattached. When coupled together, they form a stable structure suitable for operation. When detached, they allow easy access to the roller for maintenance. The coupling means ensure that the connection between the two parts is secure during operation, maintaining stability of the machine frame composition while enabling easy disassembly for maintenance purposes.
