Drum Dicing Assembly with Segmented Knife Net
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing food dicing tools face high dicing resistance, making the process laborious and increasing product costs due to the need for more powerful motor drives.
Innovation Solution
A drum dicing assembly that divides the dicing action into three steps: slicing, stripping, and dicing, using a slicing knife cylinder, a material pressing rib, and a dicing knife cylinder with a height difference between first and second dicing knives, reducing extrusion resistance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the dicing action is completed by extrusion through a dicing knife net, then the dicing function is achieved, but the extrusion resistance is large making the operation laborious
Solution Approach 1:
The dicing knife net is segmented into two distinct groups: a first group of dicing knives and a second group of dicing knives. This segmentation allows the cutting action to be divided into two sequential steps, reducing the extrusion resistance that would otherwise be required to force material through a single dense knife net.
Solution Approach 2:
The first group of dicing knives performs a preliminary cutting action, creating initial cuts in the material before it reaches the second group of dicing knives. This preliminary action reduces the resistance for the subsequent cutting phase, making the overall dicing process easier to operate.
2Ease of operation
If a single group of dicing knives is used in the dicing knife net, then the structure is simple, but the dicing resistance is high and labor-saving effect is limited
Solution Approach 1:
The dicing knife net is divided into two functional groups of knives arranged in different patterns. The first group has knives arranged in a first pattern, while the second group has knives arranged in a second pattern different from the first. This segmentation reduces dicing resistance and improves labor-saving effect while maintaining reasonable structural complexity.
3Productivity
If the knife edge portions of first and second dicing knives are at the same height, then the structure is symmetric and simple, but the cutting efficiency is reduced
Solution Approach 1:
The knife edge portions of the first and second groups of dicing knives are arranged at different heights, creating an asymmetric configuration. This asymmetry enables sequential cutting action where the first group cuts at one height level and the second group cuts at a different height level, improving dicing efficiency by preventing knife interference and enabling better material flow.
