Bulk Material Mixer With Vacuum Fixation And Dynamic Drive
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing bulk material mixing machines are limited in their ability to mix materials with varying particle sizes and specific weights, leading to separation issues during the mixing process, and are typically designed for use with plastic bags, which can result in wrinkles and material accumulation, hindering effective mixing.
Innovation Solution
A mixing machine design featuring a container holder with vacuum fixation and a pivoting drive unit, equipped with a sealing lid and conically tapered container receptacle, allows for flexible container use and prevents material separation by generating a turbulent flow with a dual-blade mixing tool and horn tool, ensuring thorough mixing without additional setup for the plastic bag.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a vibrating drive acting on the container holder is used to generate mixed material flow, then the mixing process can be performed, but materials with varying particle sizes and specific weights separate during mixing
Solution Approach 1:
The drive unit is made movable relative to the container holder through a lifting column mechanism, allowing dynamic adjustment of the drive unit's position. This dynamic configuration enables the mixing tools to effectively process materials with varying particle sizes and specific weights by adjusting the mixing action intensity and position, thereby preventing material separation while maintaining mixing productivity.
2Loss of time
If plastic bags are used as containers to avoid cleaning, then setup time is reduced, but wrinkles and material accumulation occur hindering effective mixing
Solution Approach 1:
The lifting column enables dynamic vertical movement of the drive unit relative to the container holder. This dynamic adjustment allows the mixing tools to maintain optimal contact with the container bottom and inner walls throughout the mixing process, preventing material accumulation and wrinkles even when using flexible plastic bag containers, thus maintaining mixing effectiveness while keeping setup time low.
Solution Approach 2:
The system allows adjustment of the drive unit's vertical position parameter through the lifting column. By changing this parameter, the mixing tools can adapt to the container's shape and position, ensuring consistent mixing performance regardless of container flexibility or material properties, thereby preventing wrinkles and accumulation.
3Device complexity
If the drive unit is stationary relative to the container holder, then structural simplicity is maintained, but flexible container use is limited
Solution Approach 1:
The lifting column transforms the stationary drive unit into a movable one, allowing vertical displacement relative to the container holder. This dynamic capability enables the system to accommodate various container types and positions while maintaining relatively simple structural implementation through a straightforward lifting mechanism, thus achieving both adaptability and structural simplicity.
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 design enables efficient mixing of materials with varying sizes and weights by creating a physical unit between the container and drive unit, preventing separation and allowing for easy container insertion and removal, while maintaining a sealed environment to prevent material accumulation and wrinkles.
Implementation Method 1
The container is fixed in the container holder (2) by applying a negative pressure
Implementation Method 2
it is necessary to move the material to be mixed within the container to form a flow of material to be mixed, such a flow being a turbulent flow, as a result of which the material to be mixed is thoroughly mixed
