Description

Technical Field

[0002] Carbon fiber refers to high-strength and high-modulus fiber with a carbon content of more than 90%. It ranks first among all chemical fibers in terms of high temperature resistance. It is made of acrylic and viscose fibers as raw materials and is oxidized and carbonized at high temperatures. It is an excellent material for manufacturing high-tech equipment such as aerospace. It is mainly composed of carbon elements and has the characteristics of high temperature resistance, friction resistance, heat conduction and corrosion resistance. It is fibrous and soft in appearance and can be processed into various fabrics. Because its graphite microcrystalline structure is preferentially oriented along the fiber axis, it has high strength and modulus along the fiber axis.

[0003] According to the feeding mechanism of the carbon fiber prepreg automatic cutting machine disclosed on the patent website (authorization announcement number: CN210100147U), "The utility model discloses a feeding mechanism of the carbon fiber prepreg automatic cutting machine, including a frame, a feeding drive device and a horizontally arranged feeding shaft, both ends of the feeding shaft are hinged to the feeding end of the frame, the feeding drive device is connected to the end of the feeding shaft and drives the feeding shaft to rotate, so as to drive the prepreg roll sleeved on the feeding shaft to rotate and unfold and feed the prepreg to the discharging end of the frame, and also includes a feeding drive device. The feed shaft is parallel to the feed shaft, and both ends of the feed shaft are hinged to the middle of the frame. The feed drive device is connected to the ends of the feed shaft and drives the feed shaft to rotate, so as to feed the prepreg above the feed shaft to the discharge end of the frame. During the feeding process, the feed shaft is driven to rotate, which drives the prepreg roll to rotate, so that the prepreg unfolds and moves toward the discharge end. At the same time, the feed shaft is driven to rotate, so that the feed shaft and the prepreg move synchronously to prevent the prepreg from slipping off to ensure the feeding accuracy. The utility model also discloses an automatic carbon fiber prepreg cutting machine including the above-mentioned feeding mechanism.
