Description

TECHNICAL FIELD

[0002] Low-dielectric glass fiber can effectively reduce signal transmission delay, reduce signal loss, and improve transmission efficiency and integrity, and is one of the core raw materials for manufacturing high-performance PCB substrates, thereby realizing technical breakthroughs in the fields of 5G communication, high-speed computing, advanced radar and aerospace.

[0004] As shown above, the device can separate or wind the fiber filaments together by changing the angle of the wire guide, which is very convenient. At the same time, the wire guide wheel can guide the fiber filaments to avoid direct contact between the fiber filaments and the wire guide, change the sliding friction into rolling friction, reduce the loss of the fiber filaments, and avoid breakage. When the raw materials leave the stock bin and enter the inside of the heating barrel, the raw materials need to be mixed first. However, there is no mixing device integrated on the heating barrel, so the raw materials can only be mixed by external equipment first, and then put into the heating barrel to prevent insufficient chemical reaction of the raw materials during heating. Once there is any mistake in the pre-mixing, there is no active means to remedy in the subsequent high-temperature melting process, so that the tolerance of the entire system to the raw material mixing error is extremely low, which increases the uncontrollable risk of product quality and makes the dependence on the pre-process too strong.
