Powder Layer Trimming for Lateral Waste Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems for forming ceramic tiles or slabs with thicker powder layers face inefficiencies in trimming and recycling the powder, leading to excessive material recovery and recycling challenges due to the geometry of the powder layer and the positioning of trimming blades.
Innovation Solution
The trimming blades are repositioned internally within the decreasing triangular sections of the powder layer edges, allowing for subdivision into parts with identical sections, and transfer means are used to move external powder internally, ensuring a regular rectangular section and efficient powder usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of substance
If trimming blades are positioned externally to the powder layer edges, then powder can be trimmed and removed, but excessive powder quantity must be recuperated and recycled
Solution Approach 1:
Instead of positioning blades externally to trim powder edges, the invention inverts the approach by positioning blades internally within the decreasing section of the powder layer. This internal positioning allows the blades to subdivide the powder section into two parts with substantially identical sections, thereby reducing the quantity of powder that needs to be externally trimmed and recuperated.
Solution Approach 2:
The invention applies segmentation by using trimming blades to divide the powder layer's decreasing section into two substantially identical parts. This segmentation occurs internally within the powder layer structure, allowing for more efficient powder distribution and reduced waste material that requires recycling.
2Productivity
If trimming blades are positioned internally within the decreasing section of powder layer edges, then powder distribution is optimized and recycling efficiency improves, but the device complexity increases
Solution Approach 1:
The invention applies preliminary action by positioning the trimming blades upstream within the decreasing section of the powder layer before the powder reaches the compacting station. This advance positioning allows the blades to pre-subdivide the powder section into optimized parts, ensuring efficient powder distribution and reduced waste before compaction occurs, thereby improving overall recycling efficiency without requiring complex real-time adjustment mechanisms.
