Dough Cutting Device With Segmented Vertical Blade Drive
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing dough cutting devices face challenges in achieving high-speed cutting with accurate control and reduced power consumption, particularly when cutting dough sheets with uneven weight distribution, requiring complex mechanical constructions and high power for moving heavy cutting blade components.
Innovation Solution
A device with a movable sledge and a separate, fixed-position drive for the cutting blade, allowing the blade to move vertically and reducing the weight to be accelerated, combined with independent control of horizontal and vertical blade movements for precise cutting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If the cutting blade and its drive are moved quickly to change cutting location, then high-speed cutting is achieved, but high power consumption and complex mechanical construction result
Solution Approach 1:
The cutting device is segmented into two independent drive systems: a first drive for moving the sledge horizontally and a second drive for moving the cutting blade vertically. This segmentation allows each drive to be optimized independently, with the second drive being smaller and less powerful since it only needs to move the blade vertically rather than the entire assembly horizontally at high speed.
Solution Approach 2:
The cutting operation transitions from a primarily horizontal movement (moving the entire cutting assembly along the conveyor) to a vertical movement (dropping the blade down onto the dough). By changing the primary direction of cutting action from horizontal to vertical, the mass that needs to be accelerated is dramatically reduced, lowering power requirements.
2Speed
If the cutting blade is moved quickly to adjust cutting location, then high-speed cutting is achieved, but very accurate control requirements increase
Solution Approach 1:
By separating the horizontal positioning function (first drive moving sledge) from the vertical cutting function (second drive moving blade), each drive can be controlled independently with appropriate precision for its specific task. The second drive only needs precise control for the vertical dropping motion, not for long-distance horizontal positioning.
3Speed
If heavy device components are moved quickly, then high-speed cutting is achieved, but high power consumption results
Solution Approach 1:
The cutting action is reoriented from horizontal movement of heavy components to vertical movement of the lightweight cutting blade. The blade drops vertically onto the dough from a elevated position, eliminating the need to accelerate heavy horizontal components at high speed.
4Productivity
If the cutting blade is moved horizontally along with the conveyor, then cutting keeps up with conveyor speed, but complex mechanical construction is required
Solution Approach 1:
The mechanical system is divided into independent modules: the sledge assembly that can move horizontally with the conveyor, and the blade assembly that can move vertically independently. This modular segmentation simplifies the mechanical construction by allowing each module to be optimized for its specific function rather than requiring a complex integrated system.
