Up-down vibration flattening device

Abstract

The invention discloses an up-down vibration flattening device which mainly consists of a transmission part (1), a moving part (2) and a vibration roller part (3), wherein the transmission part (1) is mounted at the bottom of a frame body of the flattening device; the moving part (2) is mounted on the frame body; the vibration roller part (3) is arranged at the upper part of the frame body and connected with the moving part (2); the vibration roller part (3) consists of four groups of vibration rollers; and every two adjacent groups of vibration rollers move relatively up and down in the axial direction under the effect of an eccentric wheel of the moving part (2). The up-down vibration flattening device disclosed by the invention has a novel, compact and reasonable structure; the transmission part adopts a variable-frequency motor which directly drives a rotation shaft with the eccentric wheel to rotate to realize up-down vibration, and can realize online adjustment of the vibration frequency according to the production process; the moving part adopts a precise linear guide rail to ensure vibration stability; and the vibration roller adopts a rachis structure so that the carbon filament is in linear contact and the carbon filament flattening effect is ensured.

Description

technical field [0001] The invention relates to an up and down vibrating flattening device. Background technique [0002] The carbon fiber prepreg impregnation production line is the key equipment for the production of carbon fiber. The carbon fiber prepreg impregnation production line realizes the uniform arrangement of carbon filaments and the surface-mounted roll-coated epoxy resin release paper on the impregnation machine and laminating machine rollers. Under the action of extrusion, the adhesive film on the release paper is pressed to the upper and lower surfaces of the carbon fiber to complete the dipping process. The carbon fiber vibration flattening device is a key part of the production line, and its flattening quality directly affects the precision of the final product. At present, the dipping production line adopts the flattening method of left and right vibrations to flatten the carbon fiber bundles. The vibration amplitude is very small. If the vibration amplit...

AI Technical Summary

Problems solved by technology

At present, the dipping production line adopts the flattening method of left and right vibrations to flatten the carbon fiber bundles. The vibration amplitude is very small. If the vibration amplitude is increased, the carbon filaments will easily break, and the vibration frequency is limited, so the flattening effect is not ideal.
