Detailed ways

The invention is further described below in conjunction with the embodiments shown in the drawings.

As shown in Figures 1, 2, 3 and 4, the fiber comb feed mechanism for the FRP board includes a supply rack 1 for placing the fiber tray 2, disposed downstream of the feed rack 1 and used to divide the fibers into A multi-bundle comb assembly and a feed roller 4 located downstream of the comb assembly for introducing hot air from the heating furnace of the FRP sheet line into the air supply portion 313 of the auxiliary tube.

The comb assembly includes a comb frame 31, a comb tooth bar 33 mounted on a lower end surface of the beam 32 of the comb frame 31 and extending downward, and the longitudinal beam 34 of the comb frame 31 is lower than A loading unit for arranging the fiber bundles on the feed roller 4 is provided at a position below the comb bar 33. The loading assembly includes an automatic take-up reel 35 mounted on the stringer 34 and a loading tether 36 wound on the automatic reel 35. The comb frame 31 has two longitudinal beams 34, the automatic winding reel 35 is mounted on one of the longitudinal beams 34, and the other of the longitudinal beams 34 is provided with a connecting buckle 37, the feeding rope The free end of 36 is provided with a connecting ring 38 that mates with the connecting buckle 37, and the connecting ring 38 is fastened to the connecting buckle 37.
