Noodle Cutting Scraper Segmentation and Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing noodle cutting technologies face issues with noodle threads sticking together, scraping teeth damage, and threads being caught at the scraper's secured position, as described in Japanese Unexamined Patent Applications and Utility Model Publications.
Innovation Solution
The apparatus includes a housing with multiple rollers and scrapers, where the second scraper's teeth are positioned downstream from the meshing point, and the first scraper has a transfer hole allowing threads to pass through, preventing sticking and damage while ensuring threads fall correctly onto the conveyor.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single scraper with comb-like teeth is used to scrape noodle threads from the roller groove, then the structure is simple, but the scraping teeth may suffer from damage such as being broken or bent due to metal fatigue
Solution Approach 1:
The single scraper is divided into two separate scrapers. The first scraper has scraping teeth that engage with the roller groove at a first position, and the second scraper has scraping teeth that engage at a second position downstream. This segmentation distributes the scraping load across two separate components, reducing the stress on individual scraping teeth and preventing metal fatigue damage.
2Productivity
If the scraper is positioned close to the meshing position of the rollers, then the noodle threads can be scraped efficiently, but the noodle threads may be caught at the scraper's secured position or at the fixing position of the scraper
Solution Approach 1:
The first scraper is positioned to scrape noodle threads from the roller groove at a first position that is upstream relative to the meshing position of the rollers. This preliminary scraping action removes threads before they reach the problematic zone near the meshing position, preventing them from being caught at the scraper's secured position or fixing position.
Solution Approach 2:
The solution introduces a spatial dimension by positioning two scrapers at different locations along the roller circumference. The first scraper operates at a first position and the second scraper operates at a second position downstream, creating a staged scraping approach that eliminates the harmful catching effect while maintaining efficient thread removal.
3Object-affected harmful factors
If adjacent teeth tips at the scraper are shifted to different positions in the circumferential direction, then noodle threads can be prevented from sticking to each other, but the scraping teeth may still suffer from damage due to uneven stress distribution
Solution Approach 1:
By dividing the scraping function into two separate scrapers, each with multiple teeth, the uneven stress distribution problem is mitigated. The first scraper handles threads at its engagement position, and the second scraper handles threads at its downstream engagement position. This segmentation ensures that teeth in both scrapers experience more uniform stress patterns compared to a single scraper with significantly staggered teeth positions.

AI summary
An apparatus for cutting out noodle can prevent damage to scraping teeth of a scraper and prevent noodle threads from being caught at a fixing position of the scraper. The apparatus includes a housing, a first roller having a first receiving portion, a second roller having a second receiving portion, a first scraper secured at a first fixing position and having first scraping teeth inserted in the first receiving portion, a second scraper having second scraping teeth, a third scraper secured at a second secured position and having third scraping teeth, and a fourth scraper having fourth scraping teeth. The first and third scrapers include first and second transfer holes, respectively. The first fixing position is located more outwardly in a horizontally outward direction than a second tooth tip, and the third fixing position is located more outwardly in the horizontally outward direction than a fourth tooth tip.
