Dough Strip Centering via Synchronous Eccentric Pressing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing dough conveyor devices fail to ensure precise center positioning of dough strips, leading to irregular cutting and inferior product quality when fed to punching devices, as separate drives for pressure elements on both sides of the dough edges result in asynchronous action, causing variations in dough triangle base lengths and weights.
Innovation Solution
The device employs pressing elements that exert pressure on the dough edges and provide a superimposed movement in the conveying direction, using eccentric drives to ensure synchronous and pulsating motion, maintaining the dough in the desired center position and preventing deformation or tearing, with adjustable components for flexibility in handling different dough widths and shapes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If separate drives for pressure elements on both sides of the dough edges are used, then the dough edges can be pressed independently, but synchronous action on the two dough edges is not guaranteed, leading to variations in dough triangle base lengths and weights
Solution Approach 1:
The patent combines two separate drive systems into a single drive mechanism that controls both pressing elements simultaneously. This merging ensures that both dough edges receive synchronous pressing action, eliminating the positioning variations that occurred with independent drives while maintaining the ability to press both edges effectively.
2Manufacturing precision
If pressing elements only act perpendicular to the conveying direction, then the dough band can be centered, but indentation, deformation, or tearing of the dough band may occur
Solution Approach 1:
The patent implements periodic pressing action where the pressing elements apply force in a rhythmic sequence rather than continuously. This periodic action, combined with the superimposed conveying direction movement, allows the dough to be repositioned gradually without sudden forces that would cause indentation or tearing, while still achieving precise centering.
Solution Approach 2:
The patent adds a movement component in the conveying direction to the pressing elements, transforming their action from purely perpendicular (one dimension) to a two-dimensional motion. This dimensional change allows the pressing elements to push the dough forward while centering it, distributing the force more evenly and preventing damage.
3Manufacturing precision
If a sliding device with a centering roller on a crank axle is used, then the dough band can be moved to the desired central position, but the device complexity increases
Solution Approach 1:
The patent designs the pressing elements to serve multiple functions: they press the dough edges to prevent deformation, simultaneously act as centering mechanisms through their synchronized motion, and provide the superimposed conveying direction movement. This multi-functionality eliminates the need for separate centering devices like crank axles and centering rollers, reducing overall device complexity.
4Productivity
If pressing elements are arranged to act on multiple dough strips in parallel, then processing efficiency increases, but the complexity of the drive system increases
Solution Approach 1:
The patent divides the pressing system into modular pressing element assemblies that can be independently positioned and driven. Each assembly handles specific dough strips, but all are controlled by the unified drive mechanism. This segmentation allows parallel processing of multiple dough strips while maintaining drive system simplicity through the common drive architecture.
