When the jacking device 14 starts to move, it can be ensured that the masterbatch is not at the lowest point of the inclined partition 29, that is, there is too much near the discharge port 13. Accumulation increases the cooling efficiency, and at the same time, it can further dry the color masterbatch through the effect of air cooling. The covering and supporting layer 17 is a cordura nylon fabric with a strength of 500D to 800D.

The upward maximum stroke of the jacking device 14 sequentially increases along the direction from the feed port 12 to the discharge port 13, and the distance between the adjacent jacking devices 14 sequentially increases along the direction from the feed port 12 to the discharge port 13.
