Pressure Roller Adjusting Device with Segmented Support Rod
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional processing machines require significant installation effort for tool changes due to rigidly mounted pressure rollers, and existing adjusting devices for pressure rollers are complex and cumbersome, especially when rollers need to be adjusted laterally or removed for specific tasks.
Innovation Solution
The adjusting device features a support rod with a noncircular cross-sectional form-fit section and a rotary section that allows the pressure roller to be easily adjusted from a pressure position to a resting position by pivoting, using a support arm seated on the rod with sections designed for secure clamping and rotational motion within a pressure roller bracket.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If pressure rollers are rigidly mounted in conventional processing machines, then the structure is simple and stable, but significant installation effort is required when tool changes are needed and the pressure rollers cannot be easily adjusted or removed
Solution Approach 1:
The support rod is divided into two distinct sections: a first section with noncircular cross-section for form-fit clamping, and a second section with circular cross-section for rotational adjustment. This segmentation allows the single component to provide both secure mounting and easy adjustability, resolving the contradiction between ease of operation and device complexity
Solution Approach 2:
The support rod transitions from a static rigid mounting to a dynamic adjustable system. The second section's circular cross-section enables rotational movement, allowing the pressure roller to be dynamically adjusted between different positions and easily removed, while the first section maintains structural stability during operation
2Ease of operation
If pressure rollers are mounted on a pivoting arm to allow adjustment from pressure position to resting position, then the ease of operation improves, but the adjusting device becomes very elaborate in constructive design
Solution Approach 1:
The invention extracts the adjustment function from a complex pivoting arm mechanism and integrates it directly into the support rod through the circular cross-section section. This eliminates the need for elaborate external adjusting devices while maintaining the ability to pivot the pressure roller between positions
Solution Approach 2:
The support rod combines multiple functions into a single component: it provides structural support, form-fit clamping through the noncircular section, and rotational adjustment capability through the circular section. This merging eliminates the need for separate adjusting mechanisms, reducing device complexity while maintaining ease of operation
3Reliability
If the support rod has a noncircular cross-section for form-fit clamping, then secure positioning is achieved, but rotational motion is prevented unless a second section is added
Solution Approach 1:
The support rod is segmented into two sections with different cross-sectional geometries. The first section's noncircular cross-section provides form-fit clamping for reliable positioning, while the second section's circular cross-section enables rotational motion. This segmentation allows both secure clamping and rotational adjustment to coexist in a single component
Solution Approach 2:
The support rod becomes a multi-functional component that simultaneously provides secure form-fit clamping and rotational adjustment capability. The first section ensures reliable positioning while the second section enables versatility for adjustment and removal, making the single component adaptable to multiple operational requirements

AI summary
The adjusting device for a pressure roller of a processing machine has a pivotable support arm carrying a pressure roller adjustable with the support arm from a pressure position into a resting position. The support arm is seated on a support rod that engages a clamping aperture of a pressure roller bracket. The support rod has a first section with noncircular cross section that forms a form-fit section cooperating with the clamping aperture of the pressure roller bracket by form-fit. The support rod has a second section arranged axially offset to the first section and forming a rotary section. It rests against the inner side of the clamping aperture and allows rotation of the support rod about its axis in the clamping aperture. The pressure roller can be pivoted easily into a resting position and/or transverse to the workpiece in the width direction with a constructively simple design.
