Powder Supplier Regulator for Uniform Width Distribution
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing powder suppliers, such as those described in Japanese Patent Unexamined Publication No. 2013-63849, face challenges in achieving uniformity of powder material supply in the width direction, leading to non-uniform density and reduced productivity in sintered bodies due to pressure loss and friction-related issues.
Innovation Solution
A powder supplier design featuring a casing with one or multiple screws and a rotatable regulator between the screws and the outlet, which regulates the powder flow and ensures uniform distribution by balancing rotational moments, thereby improving the uniformity of powder supply in the width direction without significant pressure loss.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a dispersion blade is disposed at a screw feeder outlet to scrape off material, then material discharge is achieved, but uniformity of powder supply in the width direction deteriorates
Solution Approach 1:
A regulator is introduced as an intermediary component between the screw and the outlet. This regulator rotates about a shaft perpendicular to the screw axis and actively mediates the powder flow, balancing the supply across the width direction while maintaining continuous discharge operation.
Solution Approach 2:
The regulator is designed to rotate dynamically during operation. By rotating about an axis perpendicular to the screw axis, the regulator dynamically adjusts and balances the powder flow distribution in the width direction, transforming a static discharge problem into a dynamically controllable process.
2Productivity
If powder material is transported by rotating screws, then continuous supply is achieved, but non-uniform density and pressure loss occur
Solution Approach 1:
The regulator serves as a mediating element between the rotating screw and the outlet. It receives the non-uniform powder flow from the screw and redistributes it uniformly, eliminating density variations while preserving continuous supply capability.
Solution Approach 2:
The regulator is positioned asymmetrically with its rotation shaft perpendicular to the screw axis. This asymmetric configuration allows the regulator to effectively address the non-uniform flow pattern generated by the screw, balancing the powder distribution across the width direction.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution enhances the uniformity of powder supply in the width direction, resulting in improved density distribution and productivity of sintered bodies by balancing sparse and dense regions within the casing, thus optimizing the supply process.
Implementation Method 1
one or a plurality of screws being disposed inside the casing and rotationally driven to transport the powder material in an axial direction
Implementation Method 2
The regulator has a rotation shaft perpendicular to an axial direction of the one or the plurality of screws and a width direction of the powder material discharged from the outlet, and being configured to rotate about the rotation shaft
