[0057] A blocking door that can be pulled out and opened is provided at the bottom of the material receiving box.

[0058] The speed-regulating motors in this embodiment are all servo motors.

[0059] Working principle: The first carbon fiber belt 18 and the second carbon fiber belt 19 sequentially bypass the first fixed shaft 5, the second fixed shaft 6, the second rotating shaft 3, the third rotating shaft 7, and the first rotating shaft 2. When the first rotating shaft 2 is driven by the driving motor to rotate, through the gear transmission mechanism, the second rotating shaft 3 and the third rotating shaft 7 will be driven to rotate, and the first carbon fiber belt 18 and the second carbon fiber belt 19 will be pulled forward. During this process, the electric heating rollers in the first fixed shaft 5 and the second fixed shaft 6 heat up, providing heat for the first carbon fiber belt 18 and the second carbon fiber belt 19, softening the sizing agent on the surface of the carbon fiber, and using the friction generated between the first fixed shaft 5, the second fixed shaft 6 and the carbon fiber belt to widen the fibers. The width change of the fiber widening can be achieved by adjusting the fiber tension, the vertical height of the fixed shaft, and the number of fixed shafts.

[0060] When the first carbon fiber tape 18 and the second carbon fiber tape 19 pass through the second fixed shaft 6 and the third rotating shaft 7, the first nozzle valve 8 and the second nozzle valve 14 can spray out hot melt wire, and the first carbon fiber tape 18 and the second carbon fiber tape 19 are driven by two electric push rods to reciprocate back and forth, so that the hot melt wire sprayed by the first nozzle valve 8 and the second nozzle valve 14 is distributed in a sinusoidal curve on the first carbon fiber tape 18 and the second carbon fiber tape 19, thereby evenly fixing the carbon fiber tapes to prevent fiber dispersion.

[0061] After being widened and shaped, the first carbon fiber tape 18 and the second carbon fiber tape 19 enter the conveying platform 57, and are pressed on the conveying platform 57 by the first pressing roller 22, the third pressing roller 39, the second pressing roller 23, and the fourth pressing roller 40 respectively; the downward pressure of the first pressing roller 22, the third pressing roller 39, the second pressing roller 23, and the fourth pressing roller 40 is provided by the first cylinder 20, the second cylinder 21, the third cylinder 41, and the fourth cylinder 42 respectively. After the conveying platform 57 is started, the widened carbon fiber tape is smoothly conveyed forward.

[0062] The cutter 52 is fixed on the sliding seat 36, and the sliding seat 36 is connected to the cam 24 by bolts. The cam 24 is connected to the first speed regulating motor 37 through a coupling. When the cam 24 is driven to rotate, the cam 24 is pushed downward, and the second spring 33 and the third spring 54 push upward, so that the sliding seat 36 performs an upward reset movement, thereby driving the cutter 52 to cooperate with the guide plate 53 to complete the cutting of the carbon fiber tape. Different cutting lengths can be achieved by adjusting the speed of the first speed regulating motor 37.

[0063] When the cut carbon fiber strips fall into the receiving box, the lever 28 driven by the second speed regulating motor 49 rotates, and a part of the carbon fiber strips are pushed forward by the lever 28 and fall to the front of the receiving box, and a part of the carbon fiber strips pass through the gap of the lever 28 that moves to the upper part and then move downward, and are caused by the rotating lever 28. The airflow flows in four directions obliquely downward, and the lever 28 at the outlet gap pushes the carbon fiber strips again, so that the carbon fiber strips are evenly scattered in the receiving box. When the subsequent carbon fiber prepreg process is carried out, there is no need to re-disperse the carbon fiber strips evenly, which can improve production efficiency.

[0064] The dispersion width of the carbon fiber strips in the receiving box can be adjusted by adjusting the rotation speed of the second speed regulating motor 49.
