Dryer Blowing Box Vertical Positioning Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing dryers for strip-shaped objects struggle to maintain accurate distance between the object and the hot-air outlet during the drying process, leading to inefficiencies in energy consumption and uneven drying due to the difficulty in adjusting the vertical distance across the entire width direction.
Innovation Solution
A dryer design featuring a loading and conveying unit with rotatably supported rollers and a blowing box with positioning portions that determine the vertical position of the object and outlet with high accuracy, using a cover unit to stabilize and adjust the positions of the blowing box, ensuring precise alignment and uniform air distribution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a blowing box is fastened to a retaining member with a bolt and nut through a slit, then the blowing box position can be adjusted, but the vertical distance between the conveying roller and hot-air outlet cannot be controlled with high accuracy
Solution Approach 1:
The blowing box is divided into an adjustable section (with the slit and bolt-nut mechanism for width direction adjustment) and a fixed section (where the hot-air outlet position is precisely fixed relative to the conveying roller). This segmentation allows independent optimization of adjustability and precision in different spatial directions.
Solution Approach 2:
A positioning mechanism acts as an intermediary between the adjustable blowing box and the conveying roller, ensuring that when the blowing box position is adjusted in the width direction, the vertical distance accuracy is maintained through the precise geometric relationship established by the positioning structure.
2Reliability
If an ample amount of hot air is blown to ensure drying across the entire width, then drying coverage is improved, but energy consumption increases
Solution Approach 1:
The blowing box is made dynamically adjustable in the width direction, allowing the hot-air outlet position to be optimized for different object widths. This dynamic adjustment enables precise matching of air flow distribution to the actual drying area, avoiding waste of energy on excessive air consumption while maintaining uniform drying across the entire width.
3Adaptability or versatility
If the blowing box position is adjusted using a bolt and nut through a slit, then some position flexibility is achieved, but the structure becomes complex and difficult to control
Solution Approach 1:
The blowing box structure is segmented into adjustable and fixed portions, with the adjustment mechanism limited to a specific degree of freedom (width direction). This reduces the overall structural complexity while maintaining necessary adaptability for different drying scenarios.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This design allows for precise control of the vertical distance between the object and the air outlet across the entire width, optimizing energy use by providing the appropriate amount of air for drying, resulting in uniform drying and reduced energy consumption.
Implementation Method 1
a roller on which the object to be dried is loaded, the roller having a roller axis extending in the width direction
Implementation Method 2
a first positioning portion including a first abutting portion that abuts against a first abutted portion of the first supporting portion or of a fixed member fixed to the first supporting portion, from above, the first positioning portion determining a vertical position of a part of the box body on one widthwise direction side
Implementation Method 3
a blowing box arranged above the loading and conveying unit and extending in a width direction that is orthogonal to the conveyance direction, the blowing box accommodating air pumped into the blowing box
Implementation Method 4
a dryer that dries a strip-shaped object to be dried by directing stream of air toward the object while conveying the object in a conveyance direction

AI summary
A dryer dries a strip-shaped object to be dried by directing stream of air toward the object while conveying the object in a conveyance direction. The dryer includes a loading and conveying unit that conveys the object and a blowing box arranged above the loading and conveying unit and including an outlet through which the stream of air is blown toward the loading and conveying unit. The loading and conveying unit includes a roller, supporting portions rotatably supporting the roller. The blowing box is positioned above the loading and conveying unit and formed in a box shape extending in the width direction, the blowing box including a box body that forms the outlet and accommodates air and positioning portions that determine a position of the box body in the vertical direction.
