Film Molding Device Rectifying Unit for Cooling Air Turbulence
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing film molding devices face issues with non-uniform film thickness due to turbulent cooling air flow, which affects the cooling capacity and quality of the molded film.
Innovation Solution
A film molding device is designed with a rectifying unit that includes a suction ring and suction pumps to rectify the cooling air, reducing turbulence by creating a uniform suction force and guiding the air flow, thereby ensuring consistent cooling across the film.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If cooling air is blown out from the cooling unit to cool the molding material, then the cooling capacity is improved, but the flow turbulence increases causing non-uniform film thickness
Solution Approach 1:
A rectifying unit is introduced as an intermediary component between the cooling unit and the molding material. This rectifying unit includes flow straightening elements that convert the turbulent cooling air flow into a more uniform laminar flow, thereby maintaining cooling capacity while eliminating the harmful turbulence that caused non-uniform film thickness
Solution Approach 2:
The invention changes the flow parameters of the cooling air by using flow straightening elements within the rectifying unit. These elements modify the velocity distribution and reduce turbulence intensity, transforming the cooling air from a high-turbulence state to a more uniform flow state, thus resolving the contradiction between cooling effectiveness and film uniformity
