Description

Technical Field

[0001] The utility model relates to the technical field of carbon fiber tow equalization, in particular to a tow equalization mechanism for drying carbon fiber precursor filaments. Background Art

[0002] Carbon fiber is known as the "black gold" in the material field and occupies an important position in the military and civilian markets with its excellent characteristics such as light weight and high strength. Carbon fiber precursor filaments need to be dried first and then cut into short filaments or wound during the production process.

[0003] The existing carbon fiber precursor filaments are directly cut into short filaments or wound after drying. When directly cutting into short filaments or winding, it is easy for the carbon fiber tows on the dryer to be entangled and overlapped due to relevant operations or attracted to each other due to static electricity, resulting in the carbon fiber tows not being evenly distributed on the dryer, thereby affecting the drying effect. Summary of the Utility Model

[0004] The main purpose of the utility model is to provide a tow equalization mechanism for drying carbon fiber precursor filaments, aiming to solve the technical problems of subsequent processing of carbon fiber precursor filaments after drying and the influence of static electricity on the even distribution of tows in the prior art.
