The water absorbing roller 11 includes a rotating roller 7 and a water absorbing sponge 6 mounted on the rotating roller 7. When the extruded material goes out of the cooling pond, the extruded material passes through between two water absorbing rollers of the water absorbing guide unit, and because the upper water absorbing support frame at the upper end is rotationally arranged on the mounting frame, downward force can be generated on the extruded material under the gravity action of the upper water absorbing support frame, and therefore the water absorbing sponge can absorb water on the extruded material to facilitate the next operation.
