Accurate control device for carbon fiber impregnation amount

Abstract

The invention relates to a device for accurately controlling the impregnation amount of carbon fibers, which can be used for accurately controlling the impregnation amount of the fibers in a carbon fiber wet winding process, and can solve the technical problems that the existing impregnation amount of the carbon fibers is unstable, the impregnation amount cannot be quantified, and defects of wound products are caused by poor infiltration degree of the fibers. The device can be mounted in a gum dipping system of wet winding numerical control equipment for matched use, the device comprises a set of double-roller device, a lower roller is fixed, an upper roller can lift and move along a guide, a gap between the two rollers can be adjusted with the precision of 0.001 mm through a precision adjusting mechanism, the stability of the position of the upper roller when the device works is ensured through a pressing air cylinder, and the working efficiency of the device is improved. Electromagnetic heating devices are arranged in the double rollers, and the viscosity of glue on fibers passing through a gap between the double rollers can be controlled, so that high-quality impregnated fibers with accurate and stable impregnation amount are conveyed before a product is wound.

Description

Technical field [0001] The present invention relates to an accurate control device for carbon fiber dip glue, in particular, can be used to achieve precise control of fiber dip glue in carbon fiber wet winding process. Background technique [0002] The wet winding forming process is a method of directly wraping the continuous fiber to the liquid resin system, directly wound into the core mold or lining under the tension control, and is a method of curing the molding process. One of the extensive winding processes. The wet winding process does not use the pre-leaf tape technology, and there is no pre-curing process, and the product containing the product is controlled during the dip and winding process, and the advantages and dismissivity of the dipping technology directly affects the quality of the winding article. Since the fiber yarn is wound immediately after dipping, the tape mass is not easily controlled and tested, which requires that the tissue technique reaches a certai...

Problems solved by technology

[0004] In order to solve the current technical problems of unstable carbon fiber dipping amount, unquantifiable dipping amount, and defects in winding products caused by poor fiber infiltration, the present invention provides a precise control device for carbon fiber dipping amount, which includes a Set of rollers, the lower roller is fixed, the upper roller can move up and down along the guide, the gap between the two rollers can be adjusted with 0.001mm precision through the precision adjustment mechanism, and the position stability of the upper roller is guaranteed when the device is working by pressing the cylinder. There is an electromagnetic heating device inside the double rollers, which can control the viscosity of the fiber glue solution passing through the gap between the double rollers, so as to deliver accurate and stable high-quality dipped fibers before the product is wound. The device can be installed in wet winding CNC Supporting use in the dipping system in the equipment
