AI Technical Summary

Technical Problem

In existing technologies, there are pauses in the cutting and handling process of fiber prepreg sheets, which affects the product quality and efficiency of assembly line production.

Method used

Design an integrated machine for forming fiber prepreg boards. It adopts a follow-up device to synchronize with the production line speed, so as to realize continuous operation and uninterrupted cutting and stacking. The continuity of the production line is guaranteed by the coordinated work of the axial and transverse unwinding mechanism, the cutting mechanism and the traction mechanism.

Benefits of technology

It enables continuous operation of the production line, improves product quality and work efficiency, and ensures the straightness and perpendicularity of product cutting. It is suitable for other online follow-up production lines that require continuous operation.

Abstract

This invention discloses an integrated machine for forming fiber prepreg sheets, comprising an axial unwinding mechanism, a transverse unwinding and laying / cutting mechanism, an axial melting mechanism, an axial shaping mechanism, and a traction mechanism arranged sequentially along the production line. The transverse unwinding and laying / cutting mechanism can advance synchronously with the axial material unwound by the axial unwinding mechanism when laying transverse material. After completing one layer of transverse material laying, the transverse unwinding and laying / cutting mechanism can retreat to a set position for the next layer of transverse material laying, where the front end of the transverse material laid at this set position is precisely in close contact with the rear end of the previously laid transverse material. This invention utilizes the production line's operating speed and a synchronously following device to achieve continuous production line operation.
