AI Technical Summary

Technical Problem

In existing technologies, it is difficult to position carbon fiber prepregs according to their size and thickness when flattening, resulting in low sliding and flattening efficiency. The pressure rollers are fixed and cannot be adjusted, which affects the processing effect.

Method used

By employing adjustment and positioning components, the position of the transmission roller is adjusted via an electric push rod and an annular plate, and the flattening roller is adjusted via a cylinder and a U-shaped plate, thus achieving stable conveying and extrusion flattening of carbon fibers.

Benefits of technology

It improves the stability and flattening efficiency of carbon fiber, prevents slippage, enhances the adhesion between the flattening roller and the carbon fiber, protects the carbon fiber from damage, and improves the flattening effect.

Abstract

This utility model relates to the field of carbon fiber processing technology and provides a flattening device for a carbon fiber prepreg impregnation production line, comprising: a base, characterized in that it further comprises: an adjustment component disposed on one side of the top outer surface of the base, the adjustment component comprising: two T-shaped plates, both fixedly disposed on one side of the top outer surface of the base; two transmission rollers, both movably disposed on the upper ends of the opposite faces of the two T-shaped plates; a flattening component disposed on the outer surface of the base; simultaneously activating two electric push rods to drive two sets of annular plates to move relative to or away from each other on the outer surface of the transmission rollers via connecting plates, adjusting according to the size of the carbon fiber to prevent the carbon fiber from sliding left and right on the outer surface of the transmission rollers. The two electric push rods are identical in model and power, which can better drive the two connecting plates to move synchronously. The stabilized carbon fiber passes under the positioning roller and is then conveyed to the flattening platform for flattening.
