Fiber spreading device

Abstract

The invention discloses a fiber spreading device which comprises a machine frame, a gum dipping roller, a gum extruding device and a yarn evening mechanism. The gum dipping roller is connected with a machine frame bearing and driven by a motor to rotate. The gum extruding device is composed of three gum extruding rollers, the front gum extruding roller can achieve wrap angle adjustment of fiber bundles on the gum dipping roller by adjusting the vertical position of the gum extruding device, the two rear gum extruding rollers can adjust the thickness of gum on the fiber bundles and can meanwhile provide pressing force for evenly spreading the fiber bundles, a gap between the two rear gum extruding rollers can be adjusted through a gap adjusting mechanism, and the size of the gap can be read through a gap measuring mechanism. A spring adjusting portion can automatically adjust the gap between the two rear gum extruding rollers. The yarn evening mechanism comprises a yarn evening roller and a yarn evening sleeve, wherein the yarn evening sleeve sleeves a yarn evening barrel, and a groove is formed in the yarn evening sleeve. When fibers pass through the groove, the tension of the fibers can force the fibers to evenly spread to the two sides of the groove. The fiber spreading device has the advantages of effectively controlling the spreading width of the prepreg fibers and controlling the thickness of the fibers dipped in gum.

Description

technical field [0001] The invention relates to the field of fiber product production equipment, in particular to a fiber spreading device. Background technique [0002] Composite material is a new type of material composed of two or more materials with different properties. The development of composite materials must rely on the mechanical manufacturing industry to provide it with advanced process equipment. [0003] As a kind of composite materials, carbon fiber composite materials have the advantages of higher strength than other composite materials, and are more and more widely used in aerospace and other fields. Fiber prepreg is an important raw material for the production of fiber products. In the process of producing prepreg, problems such as uneven fiber width and unstable glue content are prone to occur, resulting in excessive flash seams of prepreg and fiber The performance of the product is reduced and the production efficiency is reduced. For now, traditional m...
