Carbon fiber multifilament is usually bundled by hundreds to thousands of carbon fiber monofilaments and can be used in the preparation of composite materials, reinforcing materials, aerospace components, automotive parts, sports equipment, etc. When testing the properties such as the tensile strength of carbon fiber multifilament, it is necessary to prepare samples of carbon fiber multifilament.

[0003] After retrieval, a sample preparation device for testing the properties of carbon fiber multifilament with the publication number of CN220514580U includes a base. An impregnation tank is provided at the top of the base. A left impregnation roller and a right impregnation roller are respectively rotatably arranged at the left and right ends inside the impregnation tank. A side seat is connected to the rear side of the base. A unwinding roller, two cooperating squeezing rollers, a positioning roller, a plurality of turning rollers and a winding shaft are rotatably connected to the side seat. A wire collecting frame is detachably connected to the winding shaft, and the winding shaft is connected to a rotation driving assembly. The utility model is provided with an impregnation tank, a left impregnation roller and a right impregnation roller, which can immerse the carbon fiber multifilament bundle in glue and walk, ensuring the uniformity of impregnation and improving the consistency of sample preparation; it is provided with a plurality of turning rollers, which can greatly increase the walking path of the carbon fiber multifilament bundle, providing a time guarantee for the glue to dry, preventing the carbon fiber multifilament bundle from adhering to the wire collecting frame, facilitating the removal of subsequent samples, and improving the sample preparation efficiency.
