Description

TECHNICAL FIELD

[0001] The utility model relates to a prepreg production technical field especially relates to a longitudinal and transverse cutting modular structure. BACKGROUND

[0002] Prepreg is the intermediate material for manufacturing composite materials and its products, and constitutes the basic unit of composite materials. The uniformity and stability of its quality are important links to ensure the quality and reliability of composite materials and its products.

[0003] In the existing carbon fiber prepreg manufacturing process, the carbon fiber material impregnated with resin needs to be cooled and shaped, and then cut and wound to become finished carbon fiber prepreg cloth. Before the prepreg is wound, the edges need to be cut and the waste edges need to be collected, and the length needs to be cut, that is, longitudinal and transverse cutting.

[0004] Since prepreg is a sensitive and expensive material, it is necessary to better design the longitudinal and transverse cutting unit. In the current traditional prepreg production process, the waste edges are often cut by directly pulling the material with a winding machine, which often causes uneven cutting edges. In the continuous production process, after each roll of prepreg is wound, the prepreg needs to be cut and the next roll of prepreg needs to be wound. In the current industry production, the cutting of prepreg is mostly done manually, which is arbitrary and the cut edges are uneven and not aesthetic, causing waste of products.

[0005] At the same time, the waste edges are cut before the prepreg is wound. In the current industry production process, the waste edges are often cut by directly pulling the material with a winding machine, which often causes uneven cutting edges. Therefore, there is an urgent need for a longitudinal and transverse cutting modular structure. UTILITY MODEL CONTENTS
