Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing embryo loading devices for veneer horizontal jointing machines suffer from instability and inefficiency due to non-parallel shafts between rolling wheels and rollers, leading to uneven pressure distribution and potential peeling or scratching of veneer sheets.
Innovation Solution
The proposed embryo loading device incorporates a clutch gear wheel part with inclined shafts and a rolling wheel part featuring double rolling wheels with a polycentric coupling, ensuring stable and uniform pressure application across the veneer sheets.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If non-parallel shafts are used between rolling wheels and rollers, then the structure is simpler, but the pressure distribution becomes uneven and the operation becomes unstable
Solution Approach 1:
The rolling wheel assembly is segmented into multiple independent rolling wheels (at least two), each capable of independent rotation. This segmentation allows each rolling wheel to independently adapt to the veneer sheet thickness variations, ensuring uniform pressure distribution while maintaining structural simplicity.
Solution Approach 2:
The rolling wheels are designed with dynamic characteristics, allowing them to rotate independently on their respective shafts. This dynamic capability enables the system to automatically adjust to varying veneer thicknesses and maintain stable operation without requiring complex parallel shaft mechanisms.
2Volume of moving object
If rolling wheels are positioned at an angle to the guide bar, then the structure is more compact, but the squeezing effect is reduced and veneer sheets may peel or scratch
Solution Approach 1:
The rolling wheels are arranged in a multi-dimensional configuration with at least two rolling wheels positioned to contact the veneer sheet from different locations. This spatial arrangement provides effective squeezing action while maintaining compact structure, preventing peeling and scratching by distributing the compressive force appropriately.
3Device complexity
If a single rolling wheel assembly is used, then the device is simpler, but it cannot maintain even pressure on veneer sheets with uneven thickness
Solution Approach 1:
The rolling wheel assembly is divided into multiple independent rolling wheels, each capable of independent rotation and pressure application. This segmentation enables the system to adapt to uneven veneer thickness while maintaining overall device simplicity through modular design.
Solution Approach 2:
The system utilizes parameter changes in the form of independent rotation speeds and pressure forces for each rolling wheel. This allows the rolling wheels to automatically adjust to varying veneer thicknesses, maintaining even pressure distribution without increasing device complexity.
