Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of fiber composite material processing, and specifically relates to a glue scraping and controlling tool for a wet winding forming equipment. BACKGROUND

[0002] Fiber winding forming is one of the main manufacturing processes of resin-based composite materials. According to the process characteristics, the fiber winding forming process is usually divided into dry winding forming process, wet winding forming process and semi-dry winding forming process. In the existing technology, the wet winding forming process is as follows: after the fiber bundle is impregnated with resin glue, it is directly wound on the core mold or inner liner to form a reinforced plastic product, and then the excess glue in the filament bundle is squeezed out by using an extrusion roller to apply pressure, and finally it is cured and formed.

[0003] However, when using the existing technology for glue scraping and control, the following problems exist:

[0004] ① The diameter of the fibers in the fiber bundle is generally a few microns, and the number of fibers in a bundle is generally between several thousand and several tens of thousands. The thin and dense characteristics of the fiber bundle make it difficult for the fibers in the fiber bundle to be quickly and uniformly impregnated with glue. Although the impregnation of glue into the fiber bundle is assisted under the pressure of the pressure-adjusted extrusion roller, the effect of fiber impregnation is not very ideal due to the limited contact range and residence time of the two roller surfaces.

[0005] ② The pressure-adjusted extrusion roller rotates with the impregnation outlet roller, which can wrap the broken filaments in the fiber bundle around the pressure-adjusted extrusion roller. If not handled in time, it can cause serious winding and even filament breakage, which not only increases the workload but also seriously affects the stability of production.

[0006] ③ The extrusion pressure of the pressure-adjusted extrusion roller is adjusted by a gas cylinder, which has a relatively complex structure.

[0007] ④ The power source of the pressure-adjusted extrusion roller is compressed air, which requires additional configuration of compressed air and other auxiliary equipment, increasing additional equipment investment. INVENTION CONTENTS
