Automatic cutting device for carbon fiber prepreg

Abstract

The invention discloses an automatic cutting device for a carbon fiber prepreg, and belongs to the technical field of carbon fiber processing. The automatic cutting device comprises a fixed plate fixedly arranged at the top of a prepreg tank; a hydraulic cylinder is fixedly mounted on one side of the fixed plate; a limiting shell is fixedly mounted at the bottom of the hydraulic cylinder; an adjustable cutter mechanism is slidably connected inside the limiting shell; an attaching mechanism is arranged at the position, corresponding to the cutter mechanism, of the bottom of the limiting shell; and an aeration mechanism is further arranged in an inner cavity of the limiting shell. According to the invention, the relative position of a cutter main body can be effectively adjusted through the adjustable cutter mechanism, the adjustment adaptation capacity of a station of a cutting position is facilitated, meanwhile, isolation protection on bottom prepreg liquid is achieved through matching of a bottom liquid isolation ferrule and an air bag, and the extrusion fixing effect on carbon fibers is guaranteed through an attaching base, so that a cutter is prevented from deviating when the carbon fibers are cut, the adaptive capacity of cutting treatment of carbon fiber preimpregnation is improved, and the cutting and fixing requirements are met.

Description

technical field [0001] The invention belongs to the technical field of carbon fiber processing, in particular to an automatic cutting device for carbon fiber prepreg. Background technique [0002] Carbon fiber is a chemical fiber material with high strength and high temperature resistance. It is formed by stacking organic materials such as flake graphite microcrystals in the axial direction, and is obtained after carbonization and graphitization. Carbon fiber is processed Generally, prepreg is required to facilitate subsequent processing. [0003] Chinese patent document CN208429678U discloses a simple cutting device for carbon fiber prepreg, including a scale and a slider slidingly connected with the scale. The top is set on the scale, the bottom of the slider sleeve is provided with a fixed sleeve, the inside of the fixed sleeve is provided with a tank body and the bottom of the tank body is an opening, a movable adjustable cutter is provided in the tank body, and the sid...

[0003] Chinese patent document CN208429678U discloses a simple cutting device for carbon fiber prepreg, including a scale and a slider slidingly connected with the scale. The top is set on the scale, the bottom of the slider sleeve is provided with a fixed sleeve, the inside of the fixed sleeve is provided with a tank body and the bottom of the tank body is an opening, a movable adjustable cutter is provided in the tank body, and the side of the fixed sleeve is fixed by bolts. A cutting knife, the cutting knife is set through the fiber prepreg and the blade of the cutting knife is used to cut the fiber prepreg; it can solve the simple cutting problem of the prepreg and improve the production speed, but in practice and When in use, there are still certain defects, such as the lack of adaptability to the carbon fiber structure, the impregnation liquid in the impregnation tank is easy to adhere to the inner cavity of the tool, and the impregnation liquid is easy to adhere to the surface of the tool, which affects the carbon fiber at the bottom. cutting capacity
