Modular Roll Cutter Layout for Wide Thin Plate Processing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional roll cutter devices are limited in processing wide thin plate materials due to the need for extensive and heavy rolls, which also require frequent replacement when parts are damaged, and cannot handle materials of varying widths efficiently.
Innovation Solution
A roll cutter device with a pair of rolls and an adjustment mechanism to change the interaxial distance, allowing multiple roll units to be aligned in a straight line, enabling wider processing without extending the device, and allowing for easy replacement of damaged rolls, with additional roll units positioned on either side to further increase processing width.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of moving object
If long rolls are used to process wide thin plate materials, then the processing width is increased, but the device size and weight increase extensively
Solution Approach 1:
The patent divides the processing system into multiple roll units (first roll unit and second roll unit) arranged side by side in the width direction. Each roll unit independently processes a portion of the wide thin plate material, enabling wide material processing without requiring a single extensive roll structure.
2Area of moving object
If long rolls are used to process wide thin plate materials, then the processing width is increased, but the roll weight increases requiring frequent replacement
Solution Approach 1:
The patent segments the roll system into multiple smaller roll units with shorter axial lengths. Each roll unit has reduced weight compared to a single long roll, making them easier to handle, install, and replace when needed, while collectively providing wide processing capability through their side-by-side arrangement.
3Area of moving object
If long rolls are used to process wide thin plate materials, then the processing width is increased, but the device becomes extensive and complex
Solution Approach 1:
The patent divides the device into modular roll units that can be independently configured and adjusted. This segmentation allows for simpler individual components that are easier to maintain and replace, reducing overall system complexity compared to a single integrated long roll system.
Solution Approach 2:
The patent incorporates adjustment means for each roll unit, enabling dynamic adjustment of interaxial distances. This allows the device to adapt to different material widths and processing requirements, providing versatility without requiring a fixed extensive structure.
4Area of moving object
If long rolls are used to process wide thin plate materials, then the processing width is increased, but maintenance and replacement become difficult
Solution Approach 1:
The patent divides the roll system into separate, independently replaceable roll units. When a roll unit becomes worn or damaged, only that specific unit needs to be replaced rather than the entire long roll, significantly simplifying maintenance and reducing downtime.
5Area of moving object
If long rolls are used to process wide thin plate materials, then the processing width is increased, but deflection issues arise
Solution Approach 1:
The patent segments the roll structure into multiple shorter roll units, each with sufficient structural rigidity to maintain stability during operation. The shorter axial length of each unit reduces deflection compared to a single long roll, while the collective arrangement achieves the desired wide processing capability.

AI summary
A roll cutter device is equipped with a roll unit 5 having a pair of rolls between which a thin plate material is passed. The roll unit 5 has an upper roll 13 and a receiving roll 15, and a plurality of the roll units 5 are present in the axial direction. Three of the roll units 5 are provided in the axial direction of the rolls so that the central axes of the rolls are on straight lines in the axial direction.
