Adjustable Crimping Roller with Displaceable Bushings
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Adjusting crimping rollers for sheet materials requires high precision and skilled personnel due to micrometre-scale tolerances, leading to time-consuming and complex adjustments that can degrade product quality if not done correctly.
Innovation Solution
An adjustable roller mechanism with displaceable bushings allows for fine adjustments of the longitudinal axis of rotation through adjustable fixings and orbital displacement, enabling quick and precise alignment of crimping rollers without repositioning the external frame.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a crimping device is designed to accommodate multiple sheet material widths, then versatility is improved, but device complexity increases due to multiple fixed rollers for different widths
Solution Approach 1:
The roller assembly is designed to be movable along the crimping device body rather than fixed, allowing a single roller to adapt to different sheet material widths. The roller can be positioned at different locations along the body to accommodate various widths, eliminating the need for multiple fixed rollers for different widths.
Solution Approach 2:
A single roller assembly serves multiple functions by being adjustable to different positions along the crimping device body. This universal roller can accommodate various sheet material widths through its movable design, replacing what would traditionally require multiple specialized rollers for different widths.
2Manufacturing precision
If fixed rollers are used for specific sheet widths, then manufacturing precision is maintained for that width, but adaptability to other widths is lost
Solution Approach 1:
The roller assembly incorporates movable components that allow it to be repositioned along the crimping device body. This dynamic design enables the roller to maintain precise crimping contact for different sheet material widths while preserving manufacturing precision, as the roller can be adjusted to the appropriate position for each width rather than being fixed for a single width.
3Adaptability or versatility
If multiple crimping elements are used for different widths, then versatility is improved, but ease of operation decreases due to multiple components to manage
Solution Approach 1:
The roller assembly is designed as a single movable unit that can be easily repositioned along the crimping device body. This dynamic design simplifies operation compared to managing multiple fixed rollers for different widths, as the user only needs to adjust the position of one roller assembly rather than configuring multiple separate components.
Solution Approach 2:
The single roller assembly serves as a universal component that can accommodate various sheet material widths through its movable design. This multi-functional approach simplifies operation by eliminating the need to manage multiple specialized rollers, reducing the complexity of adjusting the device for different widths.

AI summary
An adjustable roller (20) for a crimper for sheet material, comprising: a substantially cylindrical exterior portion (21) having a first end (22) and a second end (23) with a longitudinal axis of rotation (30) extending between the first end (22) and the second end (23); and a first bushing (26) mounted inside the first end (22) of the roller and a second bushing (126) mounted inside the second end (23) of the roller. The first bushing (26) and the second bushing (126) each have a respective cylindrical bore (28, 128) with an axis that is parallel to the longitudinal axis of rotation. At least one of the first bushing (26) and the second bushing (126) is adjustably mounted inside the respective end (22,23) of the roller such the axis of the at least one of the first bushing (26) and the second bushing (126) is displaceable relative to the longitudinal axis of rotation (30).
