Vertical Juicing Mechanism And Juice Machine
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing juice machines with integral spiral propellers suffer from instability and reduced efficiency due to inadequate cutting ability and counterforce from fruit or vegetable residue, affecting juice yield and grinding stability.
Innovation Solution
A vertical juicing mechanism with a juicing cup divided into a cutting cavity and a grinding cavity, featuring a feed impeller for initial cutting and a spiral propeller for further grinding, along with a stop plane to limit upward movement and ensure stable rotation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If an integral spiral propeller structure is used, then the device complexity is reduced, but the cutting capability deteriorates
Solution Approach 1:
The single spiral propeller is divided into two separate components: a feed impeller dedicated to cutting and a spiral propeller dedicated to grinding. This segmentation allows each component to be optimized for its specific function, with the feed impeller having superior cutting edges and the spiral propeller having optimized grinding ribs, thereby resolving the contradiction between structural simplicity and cutting capability.
2Productivity
If the spiral propeller is subjected to bottom-up counterforce from residue, then the grinding process continues, but the vertical displacement occurs affecting stability
Solution Approach 1:
A guide structure consisting of a guide groove in the juicing cup and a guide rib on the spiral propeller is introduced as an intermediary mechanism. This guide structure constrains the spiral propeller's movement, allowing it to respond to bottom-up counterforce from residue while preventing excessive vertical displacement, thereby maintaining both grinding continuity and vertical stability.
3Ease of manufacture
If the feed impeller processes material in the cutting cavity, then the cutting capability is improved, but the device complexity increases
Solution Approach 1:
The juicing cup's internal space is segmented into an upper cutting cavity and a lower grinding cavity through a separator with a discharge port. This spatial segmentation allows the feed impeller to process material in the cutting cavity while the spiral propeller processes material in the grinding cavity, improving cutting capability through dedicated equipment while organizing complexity through clear functional zoning.
