Glass Fiber Coating Flow Paths for Uniform Resin Distribution
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing resin coating devices face challenges in uniformly adjusting the flow of resin around glass fibers and are bulky in the vertical direction.
Innovation Solution
The coating device incorporates first and second flow paths with branch paths that horizontally divide the resins, allowing temperature control by temperature controllers, ensuring uniform resin flow around the glass fiber while reducing the device's vertical size.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If resin flow paths are arranged vertically to coat glass fiber uniformly, then coating uniformity is improved, but device vertical size increases
Solution Approach 1:
The patent transitions from a vertical resin flow arrangement to a horizontal flow path configuration. By arranging the resin flow paths horizontally and using branch paths that extend in the horizontal direction, the device achieves uniform circumferential coating of the glass fiber without increasing vertical dimensions. This dimensional change allows the resin to be supplied uniformly around the fiber while maintaining a compact vertical profile.
2Manufacturing precision
If temperature control is added to each flow path, then coating quality is improved, but device complexity increases
Solution Approach 1:
The patent combines multiple temperature control functions into integrated temperature controllers that manage the resin temperature for both the main flow path and branch paths. Rather than having separate temperature control mechanisms for each flow path, the system uses unified temperature control units that regulate the temperature of resin throughout the entire coating process, thereby improving coating quality while limiting the increase in device complexity.

AI summary
A coating device includes: a fiber passage through which a glass fiber passes downward in a vertical direction; a first flow path which is a flow path allowing a primary resin to flow toward the fiber passage and includes a first branch path horizontally dividing the primary resin moving in a horizontal direction; a first temperature controller which is disposed along the first flow path and controls a temperature of the first flow path; a second flow path which is a flow path allowing a secondary resin to flow toward the fiber passage, includes a second branch path horizontally dividing the secondary resin moving in the horizontal direction, and is located below the first flow path; and a second temperature controller which is disposed along the second flow path and controls a temperature of the second flow path.
