Dual-Hook Kneading Assembly for Efficient, Low-Vibration Dough Processing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional automatic dough kneading machines using a single kneading hook result in inefficient dough processing, causing the dough to rotate with the hook, leading to low efficiency and significant vibration and shaking due to unbalanced forces.
Innovation Solution
A kneading dough hook assembly featuring two interconnected hooks with fool-proof mechanisms and a transmission mechanism, allowing simultaneous rotation and balanced operation, simulating hand-kneading actions with increased contact points for improved efficiency and stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a single kneading dough hook is used, then the device complexity is low, but the productivity is low and the dough rotates with the hook causing unbalanced forces
Solution Approach 1:
The single kneading hook is segmented into two separate kneading hooks (first and second hooks) mounted on separate mounting rods. Each hook operates independently to knead dough from different positions, increasing overall kneading efficiency and preventing the dough from rotating with a single hook. The segmentation allows balanced force distribution while maintaining effective dough processing.
2Stability of the object's composition
If a single kneading dough hook is used, then the structure is simple, but the machine vibrates and shakes with large extent due to unbalanced forces
Solution Approach 1:
The two mounting rods are positioned asymmetrically relative to the driving device, with the first mounting rod at a first position and the second mounting rod at a second position. This asymmetric arrangement ensures that the kneading hooks operate at different radial distances, creating balanced counteracting forces that reduce vibration and shaking while maintaining effective kneading action.
Solution Approach 2:
The second kneading hook acts as a counterbalance to the first kneading hook. By positioning the second hook on a separate mounting rod at a different position relative to the driving device, the system creates counteracting forces that offset the unbalanced forces generated by the single hook, thereby reducing machine vibration and shaking.
3Productivity
If a single kneading dough hook is used, then the device is simple to operate, but the kneading effect is not ideal and efficiency is low
Solution Approach 1:
The dual-hook assembly provides multi-functional kneading capability, where the first and second kneading hooks perform complementary kneading actions on the dough simultaneously. This universal approach covers more areas of the dough and provides more comprehensive kneading effects, improving productivity while the integrated assembly keeps operation simple through unified control.
