An intermittent assembly for driving the intermittent movement of the first round shaft 13 and the second round shaft 17 is provided on the support platform 11;

[0023] The lignin fiber material is evenly poured onto the conveyor belt 18. By controlling the movement of the conveyor belt 18 and the rotation of the loading boxes 15 through the intermittent assembly, an intermittent movement is realized in which the conveyor belt 18 moves first and then the loading boxes 15 move. By intermittently controlling the moving distance of the conveyor belt 18, the amount of material entering the loading boxes 15 is controlled to achieve quantification, and then the loading boxes 15 pour the material into the mixer 1 to achieve precise feeding control.

[0024] In the specific implementation process, as Figure 1 and Figure 4As shown in the figure, the intermittent component includes a third support rod 2 and a fourth support rod 22 respectively installed on the upper surface of the support table 11. A motor 21 is fixedly provided on the third support rod 2, and a round rod 23 is rotatably provided on the fourth support rod 22. The output end of the motor 21 is fixedly provided with a turntable 24. One side center of the turntable 24 is fixedly provided with a driving rod 25. One end of the driving rod 25 is fixedly provided with a driving shaft 26.
