Multi-layer Roller Stabilizing Structure for Stone Cutting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional stone cutting machines are unstable during operation, leading to safety issues and imprecise cutting due to tilting workbenches and limited displacement and width, making them unsuitable for cutting large stones.
Innovation Solution
A multi-layer roller stabilizing structure with upper and lower sliders for relative displacement and a three-layer roller set that links the workbench and roller rack for continuous stabilization, allowing extended displacement and width, and a detachable workbench for easy assembly and cleaning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a traditional single-layer rail workbench is used, then the structure is simple, but the workbench becomes unstable and tilted upwards during cutting operations
Solution Approach 1:
The workbench structure is segmented into multiple layers with independent roller sets. Each roller set consists of upper rollers, middle rollers, and lower rollers that can move independently, allowing the workbench to maintain stability while cutting through thick materials without tilting.
Solution Approach 2:
The invention transitions from a single-layer rail structure to a multi-layer three-dimensional roller rack structure. This adds vertical dimensionality with upper, middle, and lower rollers positioned at different heights, creating a stable support system that prevents workbench tilting during cutting operations.
2Device complexity
If a traditional fixed-size workbench is used, then the structure is simple, but the machine cannot cut large stones and has limited displacement distance
Solution Approach 1:
The workbench is designed with dynamic, movable roller racks that can extend and retract. The upper and lower rollers can move along the rails to adjust the workbench position and extend the cutting stroke, allowing the machine to handle larger stones while maintaining portability.
Solution Approach 2:
The invention adds extendability in the longitudinal direction through multiple roller racks that can move relative to each other. This creates an extended cutting stroke beyond the machine's fixed body length, enabling cutting of large stones without requiring a permanently large machine structure.
3Area of stationary object
If the workbench is made wider to hold large plates, then the placement area increases, but the machine becomes less portable and harder to transport
Solution Approach 1:
The workbench is divided into modular sections with independent roller racks. Each section can be moved and positioned independently, allowing the workbench to provide a wide stable cutting surface when needed while maintaining the ability to be disassembled or reconfigured for transport.
Solution Approach 2:
The roller racks are designed to be dynamically adjustable and movable. The upper and lower rollers can move along their rails to extend the workbench width and length as needed for large plate cutting, then retract when not in use, maintaining portability while providing extensive placement area when required.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution stabilizes the workbench during cutting, enabling safe and precise operations, extends the cutting stroke by 1.6-fold, and facilitates the cutting of larger stones with a wider surface area, improving safety and convenience.
Implementation Method 1
each of the roller sets is a three-layer combination of an upper roller, a middle roller and a lower roller
Implementation Method 2
the lower sliders are disposed between the middle roller and the lower roller

AI summary
A multi-layer roller stabilizing structure of a stone cutting machine, comprising: a base, a water storage basin, a slider assembly, a workbench and a bench rack. The water storage basin is disposed on the base. The slider assembly includes a roller rack and plural upper sliders and lower sliders. Two sides of the roller rack are provided with an upper roller, a middle and a lower rollers respectively. The upper and the lower sliders are respectively disposed between the upper, the middle and the lower rollers. The bench rack is disposed on the upper sliders, the lower sliders are disposed on the base. The workbench and the bench rack are linked to move with the upper sliders. The upper and the lower sliders thereby enabling offseting from top-to-bottom. The roller rack is displaced by linkage, and continuously stabilizes the workbench and extends a distance of displacement for the workbench.
