Problems solved by technology
However, the thickness along the fiber laying path will be uneven during continuous turning, so that the local thickness of the final part does not meet the design requirements of the part. At the same time, due to the limitation of technical characteristics, the fiber turning angle is limited and the laying speed is extremely low.
3D printing continuous carbon fiber is printed with a single continuous and small-width fiber tow, which can achieve large fiber steering, but the manufacturing efficiency of 3D printing continuous fiber is extremely low due to the single fiber tow and small width

The invention discloses an automatic laying system for variable-angle carbon fibers, which includes a frame, a tow feeding device, a channel device, a cutting device, a resin feeding device, a steering roller and a compacting roller, and a plurality of tow feeding devices are arranged on the machine On the frame, each tow feeding device includes a tow reel roller and a first driver that drives the tow reel roller to rotate, and the channel device includes a feed hole and a discharge hole, and the carbon fiber tow enters from a feed hole and passes through A discharge hole is discharged, and the cutting device is used to cut the carbon fiber tow relative to the discharge hole. The resin feeding device includes a resin feeding mechanism, a resin heating mechanism and a splitter, and the carbon fiber tow is discharged from the discharge hole and the resin shunted into the splitter After being combined on the steering roller, the steering roller drives the steering, and then is flattened on the mold by the compacting roller. The carbon fiber tow combined with the liquid resin has a strong steering ability without tow wrinkles, ensuring that the laying put quality.
Description
