AI Technical Summary
Existing optical fiber coating supply systems suffer from time-consuming and ineffective methods in eliminating air bubbles, which affects the quality of the optical fiber.
Design a feeding and defoaming device that includes a main feed tank and a buffer tank. By combining a feeding pipe, a discharge pipe and a bubble detection device, the flow of paint and the rising of bubbles are controlled. The volume and insulation temperature of the buffer tank are used to make the bubbles rise to the surface of the paint and be discharged. A return pipe and a defoaming device are set to ensure a bubble-free paint supply.
It effectively improves the bubble elimination effect, avoids coating bubble defects, improves optical fiber quality, and has a simple structure and low cost.
