Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing plant extractors, such as sugar cane mills, face inefficiencies due to misalignment between rotating shafts, leading to irregular wear in transmission gearing and loading bearings, requiring large motors and a robust foundation to handle torsion demands.
Innovation Solution
The implementation of oscillating bearing blocks with ball and socket joints allows for spherical freedom and independent impulse sources anchored by supporting arms, enabling the rollers to adjust and reduce misalignment, improving traction and juice extraction efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional fixed bearing blocks are used to support rollers, then the structure is simple and robust, but misalignment between rotating shafts occurs during operation causing irregular wear in transmission gearing and bearings
Solution Approach 1:
The patent applies the dynamics principle by replacing fixed bearing blocks with oscillating bearing blocks that can dynamically adjust their position. The bearing blocks are connected through ball and socket joints that allow spherical movement, enabling the system to adapt to misalignment between rollers during operation. This dynamic adjustment capability resolves the contradiction by maintaining alignment stability while preventing irregular wear, thereby extending component service life.
Solution Approach 2:
The patent employs parameter changes by allowing the bearing blocks to change their spatial position and orientation parameters through oscillation and spherical movement. The ball and socket joints enable changes in angular parameters, allowing the bearing blocks to compensate for misalignment. This resolves the contradiction by maintaining optimal alignment parameters during operation, reducing wear, and extending component life.
2Power
If large motors are used to handle torsion demands, then sufficient power is provided, but energy demand and system complexity increase
Solution Approach 1:
The oscillating bearing blocks with ball and socket joints reduce misalignment and friction during operation, allowing for more efficient power transmission. This dynamic adjustment reduces the energy losses associated with misalignment, enabling the use of smaller motors while maintaining sufficient torsion handling capability, thereby resolving the contradiction between power and energy demand.
Solution Approach 2:
The patent converts the potential harm of misalignment into a benefit by using the oscillating mechanism to actively compensate for it. The ball and socket joints transform what would be harmful friction and wear into controlled spherical movement, improving efficiency and reducing the power required to overcome resistance, thus resolving the contradiction between power capability and energy consumption.
3Device complexity
If fixed roller positions are used, then the structure is simple, but misalignment causes irregular wear and reduced efficiency
Solution Approach 1:
The patent introduces dynamic oscillating bearing blocks with ball and socket joints that allow the rollers to adjust their positions automatically during operation. This dynamic capability maintains proper alignment and contact between rollers, ensuring consistent traction efficiency without requiring complex fixed positioning mechanisms. The solution resolves the contradiction by achieving high reliability through simple dynamic adjustment rather than complex fixed structures.

AI summary
The invention relates to a mill juicer for plants, in which the transmission of power to the mill is novel owing to the design of the structure on which the juice extraction mechanisms are mounted, the elements that allow the set of rollers to rotate. In order to absorb the misalignment resulting from the operation and the construction of the mill, the invention includes the use of efficient elements, for example: self-aligning bearings mounted on a bearing block designed to support the loads of the mill, while allowing misalignment and maintaining lubrication of the bearing. The assembly of gear motors is mounted on the solid shaft of each of the rollers, the arrangement of three rollers rotates in opposing directions and having finishes for directing the material to a central zone and producing greater friction between the material to be processed and the rollers, thereby providing an efficient juice extraction.
