Air Knife Cleaning Tips with Elastic Movable Structure
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing air knife cleaning apparatus faces challenges in maintaining accurate contact between cleaning tips and the lips of the air knife due to changes in the positional relationship between the upper and lower lips, leading to inefficient removal of foreign substances, especially when the tips wear or deform over time.
Innovation Solution
The air knife cleaning apparatus incorporates a left and right moving module with a driving unit, first and second front and rear moving members, and elastic members to ensure the cleaning tips remain in close contact with the lips, using inclined scraping portions and inner surface cleaning tips to effectively remove foreign substances regardless of positional changes or tip wear.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the positional relationship of the upper lip and lower lip is adjusted to control gas jetting state, then the gas jetting pressure is optimized, but the cleaning tips are separated from the lip front surfaces causing foreign substance removal failure
Solution Approach 1:
The cleaning tips are designed to be movable along the front surfaces of the upper and lower lips rather than fixed. This dynamic structure allows the cleaning tips to automatically adjust their positions to maintain continuous contact with the lip surfaces even when the lips are repositioned for gas jetting optimization, thereby resolving the contradiction between maintaining reliable gas jetting pressure and ensuring precise cleaning tip contact.
2Productivity
If cleaning tips are used to remove foreign substances, then cleaning effectiveness is achieved, but the tips wear or deform over time causing contact loss and reduced removal efficiency
Solution Approach 1:
The cleaning tips are designed with movable structures that allow them to dynamically adjust their positions along the lip front surfaces. This dynamic capability compensates for wear and deformation of the tips over time, maintaining reliable contact and consistent cleaning effectiveness without requiring frequent replacement or repositioning of the tips.
