Segmented Roller Press Frame with Elastic Damping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing machine frames for roller presses are either heavy and expensive to produce, require extensive material, or are prone to torsion and misalignment due to inadequate force absorption, leading to inefficient shredding and high maintenance costs.
Innovation Solution
The machine frame is subdivided into intersecting axial and radial frames, with radial frames absorbing radial forces elastically and axial frames handling axial forces, using a belt system with elastic damping elements and welded connections to prevent torque transmission and allow easy assembly and maintenance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a closed frame with welded elements and shear bolts is used, then the frame can absorb radial and axial forces effectively, but the manufacturing becomes material-intensive and costly
Solution Approach 1:
The machine frame is divided into separate axial frame and radial frame components that can be assembled together. The axial frame absorbs axial forces while the radial frame absorbs radial forces, allowing each component to be optimized independently and reducing overall material usage compared to a fully welded closed frame.
Solution Approach 2:
The connection method between frame components is changed from rigid welded connections to elastic damping elements. This allows the frame to absorb forces effectively while using less material, as the elastic elements provide the necessary flexibility and force absorption without requiring excessive structural material.
2Stability of the object's composition
If a cuboid closed frame with chords and beams is used, then the frame structure is rigid and stable, but the weight increases significantly
Solution Approach 1:
The frame is segmented into axial and radial components that work together to provide stability. This segmentation allows each part to be lighter while maintaining overall structural rigidity through their coordinated arrangement and connection via elastic damping elements.
Solution Approach 2:
Elastic damping elements are used instead of rigid connections between frame components. These flexible elements provide the necessary structural stability while being significantly lighter than traditional welded beams and chords, reducing the overall frame weight.
3Ease of manufacture
If an open design on one side is used to simplify assembly, then the manufacturing becomes easier, but the frame becomes prone to twisting under axial forces
Solution Approach 1:
The frame is divided into modular axial and radial components that can be assembled separately and then connected. This segmentation maintains assembly simplicity while the specific arrangement of these segments provides the structural stability needed to resist twisting under axial forces.
Solution Approach 2:
The connection characteristics are changed from rigid welded joints to elastic damping element connections. This allows the frame to accommodate axial forces without twisting while maintaining ease of assembly, as the elastic elements provide flexibility and force distribution without requiring complex rigid connections.
4Ease of repair
If quickly removable end pieces are provided for maintenance, then the rollers can be removed quickly, but the frame structure becomes more complex
Solution Approach 1:
The frame is already segmented into modular axial and radial components. This existing segmentation facilitates easy removal and reassembly of rollers for maintenance while avoiding the need for additional complex removable end pieces, as the modular structure itself enables quick access to internal components.

Function Achieved in This Case
This design allows for efficient absorption of radial and axial forces without torsion, reducing weight and production costs, enabling easy assembly and maintenance, and ensuring homogeneous pressure distribution for improved shredding performance.
Implementation Method 1
The radial frames are elastically mounted in elastic damping elements. The radial forces are transferred via the vertical beams to the belts of the belt system, which are elastically mounted in elastic damping elements.
