Variable Blade Speed for Scattering-Free Noodle Cutting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing instant noodle production methods struggle to cut noodle strings of varying lengths without scattering them, particularly for short noodle strings required for diverse customer tastes, as high rotary blade speeds cause viscous noodle strings to scatter during cutting.
Innovation Solution
A noodle string treatment apparatus with a control device that adjusts the blade edge peripheral speed of a rotary blade, combined with a noodle string stabilizing roller and conveyor system, to manage the cutting process, ensuring the blade edge peripheral speed is one to four times the noodle string speed and periodically changed between cutting points, preventing scattering by maintaining stable cutting conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the rotating speed of the rotary blade is increased to increase the number of cuts per unit time, then productivity is improved, but the noodle strings scatter during cutting due to high blade speed
Solution Approach 1:
The patent applies dynamics by making the blade edge peripheral speed variable during rotation. The control device changes the blade edge peripheral speed at specific timing during the rotation of the rotary blade, allowing the blade to adapt its speed to the cutting requirements and prevent scattering while maintaining high productivity.
Solution Approach 2:
The patent changes the parameter of blade edge peripheral speed dynamically. By controlling the blade edge peripheral speed to be within a specific range (1-4 times the noodle string speed) and changing it at appropriate timing during rotation, the system achieves both high cutting efficiency and prevents noodle string scattering.
2Productivity
If the blade edge peripheral speed is maintained at a constant high speed to increase cutting efficiency, then productivity is improved, but the noodle strings cannot be effectively prevented from scattering
Solution Approach 1:
The system transitions from constant speed to dynamic speed control. The blade edge peripheral speed is continuously adjusted during rotation based on the cutting phase, enabling the blade to maintain optimal speed for both efficiency and precision throughout the cutting cycle.
Solution Approach 2:
The control device applies periodic changes to the blade edge peripheral speed during rotation. By changing the speed at specific periodic intervals corresponding to the rotation cycle, the system ensures that cutting occurs at optimal speeds while maintaining overall high productivity.
3Productivity
If the noodle strings are cut at high speed to maintain manufacturing efficiency, then productivity is improved, but the viscous noodle strings scatter due to insufficient cutting control
Solution Approach 1:
The control device implements feedback control by monitoring the rotation state of the rotary blade and adjusting the blade edge peripheral speed accordingly. This feedback mechanism ensures that the blade speed is optimally controlled during cutting of viscous noodle strings, preventing scattering while maintaining manufacturing efficiency.
