Automatic fiber collecting device for carbon fibers

The invention discloses an automatic fiber collecting device for carbon fibers and relates to the technical field of carbon fiber production equipment. According to the automatic fiber collecting device, a winding set for the carbon fibers is arranged on a fiber withdrawing roller. A heating box is arranged on the right side of the fiber withdrawing roller. A fiber guiding wheel is arranged on the right side of the heating box and connected with a fiber guiding motor. A fiber guiding poking body is arranged on the right side of the fiber guiding wheel. A fiber collecting machine is composed of a plurality of fiber collecting-winding pipes, compression rollers and a fiber collecting motor. The compression rollers are arranged in correspondence with the fiber collecting-winding pipes. The fiber guiding poking body is movably connected with the fiber collecting-winding pipes in a contact mode. Each compression roller is arranged outside the corresponding fiber collecting-winding pipe in a closely attached mode.
