Slurry Scraping Mechanism With Damping Spring For Abrasive Production
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing abrasive production technologies face challenges in accurately controlling slurry supply, leading to poor shape completeness and increased production costs, with existing methods damaging equipment and resulting in incomplete abrasive shapes and low yield.
Innovation Solution
A slurry scraping mechanism with a damping spring and torsion spring adjusting component, combined with a V-shaped scraping plate, is used to uniformly fill cavities on a belt mold, preventing slurry accumulation and ensuring complete abrasive structure formation, while a syringe applying mechanism provides quantitative slurry application and a residual cleaning mechanism removes excess slurry.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a rigid scraping mechanism is used to fill cavities with slurry, then filling efficiency is improved, but the belt mold or machine is easily damaged
Solution Approach 1:
The patent applies beforehand cushioning by introducing a damping spring between the scraper and the support structure. This spring absorbs impact forces before they reach the belt mold, preventing damage while maintaining scraping pressure for effective slurry filling. The spring acts as a pre-established protective element that cushions against potential harm.
2Manufacturing precision
If slurry is applied in large amounts to ensure complete filling, then filling completeness is improved, but slurry accumulation occurs and affects subsequent filling
Solution Approach 1:
The patent applies local quality by designing the scraper with a V-shaped cross-section. This geometry concentrates the scraping action at the center while allowing slurry to be evenly distributed to both sides, preventing accumulation. The local V-shape creates different flow paths and pressure distributions across the width of the belt mold, ensuring complete filling without excess accumulation.
3Device complexity
If the scraper is fixed rigidly to the support, then structural simplicity is improved, but the scraping pressure cannot be automatically adjusted
Solution Approach 1:
The patent applies dynamics by replacing the fixed rigid connection with a dynamic spring-based suspension system. The damping spring allows the scraper to move vertically in response to varying slurry viscosity and filling requirements, automatically adjusting scraping pressure without complex control mechanisms. This dynamic adaptation maintains optimal performance across different operating conditions.
4Quantity of substance
If multiple batches of precursor shaped abrasives are prepared manually, then sufficient quantity is obtained, but production efficiency remains low
Solution Approach 1:
The patent applies continuity of useful action by enabling continuous slurry application and scraping operations on the belt mold. The system processes material in a continuous flow rather than batch-by-batch manual operations, with the scraper continuously removing excess slurry as the belt moves. This continuous operation dramatically increases production efficiency while maintaining sufficient output quantity.

Function Achieved in This Case
