when the heat of the fibers is led out through the cooling separation plate 5 and the liquid nitrogen, namely the fibers are stopped to be input after being cooled, the first motor 8 works to drive the turning and lifting rods 16 on the two turning plates 15 to rotate to a state of keeping vertical (refer to the orientation of the turning and lifting rods 16 in figure 1, the turning and lifting rods 16 do not influence the movement and discharge of the subsequent pushing plates 21), the two electric push rods 22 are driven to extend and drive the two extending plates 23 to extend out of the two accommodating grooves, so that the two pushing plates 21 and the two extending plates 23 can better push the fibers in the material cavity, the two second motors 19 are driven to work to drive the two lead screws 20 to rotate, the two pushing plates 21 are driven to move to one side close to the discharge port 34 from one side of the material cavity close to the external air pipe 25, the side sealing plate 36 rotates along the steering shaft 35 to open the discharge port 34, and most of the cooled fibers are discharged, a small part of fiber is remained in the material cavity;

driving the two electric push rods 22 to contract to the shortest and driving the two extending plates 23 to contract into the accommodating grooves, and moving the two pushing movable plates 21 to one side close to the discharge port 34; at this moment, two second fans 27 are driven to work to send outside air into the material cavity, and residual fibers in the material cavity are blown, and two micro motors 30 are driven to work to drive the driving rods 31 and the extending strips 32 to rotate, so that two telescopic hoses 28 are driven to rotate circularly in the two extending air pipes 25 respectively around the steel rings 33, and the exhaust ports of the telescopic hoses 28 are continuously adjusted in the extending air pipes 25, thereby being beneficial to blowing the rapidly flowing air to all places in the material cavity, and being convenient for rapidly blowing out the residual fibers (the first fans 7 and the second fans 27 are both electrically connected with an outside power supply, and ensuring the continuous work of the existing technology).

Finally, it should be noted that: although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments or portions thereof without departing from the spirit and scope of the invention.
