A first drying fan 203 is fixedly installed, and a waste heat recovery pipe 204 is movably installed on the outer end of the roller 201 on the other side of the drying box 104, and the waste heat recovery pipe 204 is fixed to the outer end of the drying box 104, and an exhaust cone 205 is fixedly installed on the waste heat recovery pipe 204, and the exhaust cone 205 is located at the rear of the first drying fan 203, and the interior of the roller 201 is a hollow structure. The noodle drying component 200 also includes an exhaust cone 206 fixedly installed between the front of the first drying fan 203 and the air inlet pipe 202.

[0025] Specifically, a high-speed papermaking machine is an efficient device for converting fiber pulp, waste paper or other similar materials into paper. The hollow roller 201 in the drying box 104 in the main body 100 of the high-speed papermaking machine can input hot air into its interior through the first drying fan 203 through the air inlet pipe 202 during the paper conveying and drying, so as to dry the surface of the paper being conveyed, thereby ensuring the uniformity of the paper drying.
