Solution Overview
Problem
Conventional powder compression molding machines are inefficient in producing solid milk with high porosity and shape-retaining performance at low compression force, often resulting in crumbling during collection, which reduces fabrication efficiency.
Innovation Solution
A powder compression molding machine with a slide plate, dual molding die sections, and synchronized upper and lower punches that allow for low-speed compression molding with high porosity without throughput reduction, using compact discharge zones to collect compacts without damage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If compression force is reduced to achieve high porosity (30% or more), then porosity is improved, but molding speed must be reduced to prevent compact damage during discharge and collection
Solution Approach 1:
The die is divided into multiple sections (first die section and second die section) that can be independently positioned. This allows simultaneous compression molding in one section while discharge and collection occur in another, eliminating the need to reduce molding speed to prevent compact damage during collection.
Solution Approach 2:
The invention introduces a spatial dimension by positioning die sections at different locations (compression molding position vs. discharge position). The slide plate moves die sections between these positions, enabling parallel execution of compression molding and discharge operations without interfering with each other.
2Manufacturing precision
If conventional tableting machines are used for low compression force molding, then porosity is improved, but compacts crumble during collection
Solution Approach 1:
The discharge operation is extracted from the compression molding position and performed at a separate discharge position. The slide plate moves the die section from the compression molding position to the discharge position where compacts are gently discharged onto a collection plate, preventing crumbling while maintaining high porosity.
3Manufacturing precision
If compression molding is performed at low compression force, then porosity is improved, but fabrication efficiency is reduced
Solution Approach 1:
The invention enables continuous operation by having multiple die sections working in different phases simultaneously. While one die section performs compression molding, another performs discharge and collection. The slide plate continuously moves die sections between positions, maintaining continuous production flow without interruption or speed reduction.
4Ease of operation
If conventional discharge methods are used, then collection is simple, but compacts are damaged during collection
Solution Approach 1:
The discharge position is designed at the same horizontal level as the collection plate, eliminating the need for lifting or dropping compacts. The slide plate moves the die section horizontally to discharge compacts directly onto the collection plate at equipotential position, preventing damage while maintaining operational simplicity.

AI summary
A powder compression molding machine is configured such that a plurality of lower and upper punches 61, 41 are allowed to enter a plurality of through-die holes 31 provided in first and second molding die sections 32, 33 of a slide plate 3 in a compression molding zone 21 to compressively mold powder and the slide plate 3 is slid to push out compacts downward and collect them in compact discharge zones 22a, 22b. Even when powder is compressively molded at a low compression force into solids having high porosity, compacts can satisfactorily be molded and collected without crumblingness, the compacts having sufficient high porosity and being dissolvable in water or the like.
