Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional air knife systems face difficulties in smoothly adjusting and accurately measuring the vertical angle due to narrow mounting positions and interference with surrounding equipment, leading to reduced production efficiency.
Innovation Solution
An air knife system with a rotating mechanism and angle measurement apparatus, including a screw shaft, power transmission unit, and scale indicators, allows for precise adjustment and measurement of the air knife's vertical angle by rotating the gas supply pipes and using gear mechanisms and elastic members for accurate positioning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the air knife mounting position is narrow and surrounded by equipment, then the space available for adjustment is limited, but smooth angle adjustment is required
Solution Approach 1:
The angle adjusting apparatus is integrated within the existing mounting structure. The screw shaft, moving body, and angle adjusting lever are nested within the bracket assembly, allowing smooth angle adjustment without requiring additional external space. The mechanism fits within the narrow mounting area while maintaining full adjustment functionality.
Solution Approach 2:
The angle adjusting apparatus uses a dynamic screw mechanism that converts rotational motion of the screw shaft into linear motion of the moving body, which then rotates the angle adjusting lever to change the air knife angle. This dynamic mechanism enables smooth continuous adjustment within the limited space.
2Productivity
If the air knife angle is not accurately measured during working processes, then production efficiency is reduced, but accurate measurement is required
Solution Approach 1:
The scale indicator provides visual feedback on the angle adjustment position. As the angle adjusting lever rotates, the scale indicator moves along the scale to indicate the current angle setting, allowing operators to accurately measure and control the air knife angle during working processes, thereby improving production efficiency.
3Ease of operation
If a complex angle adjustment mechanism is introduced to enable smooth adjustment in narrow space, then the device complexity increases
Solution Approach 1:
The screw shaft serves multiple functions: it provides the rotating connection between the bracket and moving body, acts as the driving element for the moving body, and serves as the rotational axis for the angle adjusting lever. This multi-functionality reduces the number of separate components needed, simplifying the overall mechanism while maintaining smooth adjustment capability.

AI summary
Proposed is an air knife system having an angle adjusting apparatus. When a screw shaft is rotated, a moving body is moved in a vertical direction, and an angle adjusting lever receives a moving force of the moving body through a shaft member, a rotating body, and a movable rail, so that the angle adjusting lever is rotated with respect to a pipe center. In this process, the rotating body is moved together with the moving body and is rotated around the shaft member, and the movable rail is rotated together with the rotating body and is spaced apart or is approached to the pipe center. Therefore, the angle adjusting lever rotates a first gas supply pipe, and changes a vertical angle of an air knife with respect to a plated steel sheet.
