Rotatable Creasing Roller for Variable Ridge Spacing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing devices for stamping creases into material layers are laborious and time-consuming to adjust for varying crease distances, resulting in residual gaps that require additional segmented elements to maintain roller balance.
Innovation Solution
A device with a main roller body and adjustable creasing foils, where the creasing blades are indirectly mechanically coupled, allowing for angular rotation of additional foils to vary the creasing ridge distance without segment-shaped gaps, ensuring balanced rotation and easy format changes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If segmented trays are used to adjust creasing blade positions, then the creasing distance can be varied, but residual gaps remain that require additional segmented elements to fill, increasing device complexity and adjustment time
Solution Approach 1:
The creasing roller is divided into a stationary main roller body and a rotatable auxiliary roller body that can be independently adjusted. This segmentation allows the auxiliary roller to be rotated to different angular positions to vary the creasing distance, while the stationary main roller provides a stable base. The segmentation eliminates the need for complex segmented trays and gap-filling elements, as the auxiliary roller's rotation naturally accommodates any creasing distance requirement without creating residual gaps.
2Adaptability or versatility
If segmented trays with adjustable positions are used, then crease format can be changed, but the adjustment process becomes very time-consuming and laborious
Solution Approach 1:
The auxiliary roller body is designed to be rotatable relative to the main roller body, enabling dynamic adjustment of the creasing blade position. By simply rotating the auxiliary roller to different angular positions, the creasing distance can be quickly varied without time-consuming assembly or gap-filling operations. This dynamic rotation mechanism transforms a static, laborious adjustment process into a simple, rapid rotational movement.
3Stability of the object's composition
If additional segmented elements are added to fill gaps, then the roller radius can be kept constant, but the device complexity and number of parts increase
Solution Approach 1:
The invention extracts and eliminates the need for additional segmented gap-filling elements by using a rotatable auxiliary roller body. The auxiliary roller's rotation capability naturally accommodates all creasing distance variations without creating residual gaps that would require extra elements. This extraction simplifies the device by removing unnecessary components while maintaining constant roller radius and smooth material transport.
