Carbon fiber short-cut production line sizing device

Abstract

The invention discloses a carbon fiber short-cut production line sizing device which comprises a faceplate provided with a tension adjusting device, a godet, a rack, a rectangular frame fixed at the upper end of the rack and a sizing tank positioned below the rectangular frame and fixedly connected with the rack through bolts. A sizing roller partly soaked in size is arranged in the sizing tank, a size extruding device for extruding excessive size on carbon fiber and enabling the same to drip into the sizing tank for recycling is arranged on the rectangular frame, and after the carbon fiber is sized and extruded, extruded excessive size is enabled to drip into the sizing tank for recycling. The carbon fiber short-cut production line sizing device meets sizing application needs on a small-amount carbon fiber short-cut production line and is low in manufacturing cost, simple and reliable to operate and easy to clean and maintain.

Description

technical field [0001] The invention relates to a chopped carbon fiber production device, in particular to a sizing device for uniformly sizing the carbon fiber before it is chopped. Background technique [0002] Carbon fiber is often added to resin, metal and other materials as a reinforcing material to give full play to its light weight and high strength characteristics. Carbon fiber reinforced composite materials are widely used in aerospace, automobile, construction, sports and entertainment products and other fields. Carbon fiber used for reinforcement is mainly divided into continuous carbon fiber and discontinuous carbon fiber, among which chopped carbon fiber is an important application form of discontinuous carbon fiber. Compared with continuous long fibers, short-cut carbon fibers have uniform comprehensive properties and can be combined with traditional molding methods such as injection molding, spraying and mixing. The manufacturing process is simple, more flexi...

AI Technical Summary

Problems solved by technology

[0003] In the production process of chopped carbon fiber, carbon fiber and rollers and other manufacturing equipment rub against each other to produce a large amount of fuzz, resulting in a decline in the quality of carbon fiber. When too much fuzz accumulates, it will be wound on the roller, causing the carbon fiber tow to be broken, resulting in unsmooth production. conduct

In addition, the impregnation between carbon fiber and resin without sizing treatment is poor, resulting in weak interfacial adhesion after carbon fiber composite, which affects the full play of carbon fiber performance
