[0030] A hot air distribution method for a low-energy hot air hood for a high-speed paper machine comprises the following steps: The first motor 24 drives the first blade 25 to rotate, thereby drawing in external air through the first through-hole 23. During the process, the air is filtered by the dust filter 27, and then the air is transported to the bottom through the first blade 25, and at the same time heated by the gaps between the heating wires 28. The air then enters the diversion chamber 13 for diversion, so that the air evenly enters each diversion hole 14, and is transported into the corrugated hose 4 through the diversion hole 14. The air is then transported out through the support pipe 41 to dry the paper at the bottom. The external air is filtered by the dust filter 27 to ensure air quality and avoid paper pollution. Then, the air is heated by the heating wire 28 to ensure uniform temperature distribution and avoid uneven drying. Then, through the design of the diversion chamber 13 and the diversion hole 14, the air is evenly transported into the corrugated hose 4, ensuring that the hot air evenly covers the surface of the paper to prevent local over-drying or over-wetting. The design of the whole process improves the efficiency of hot air utilization, reduces energy consumption, and achieves energy-saving effects. During S2, the second motor 51 drives the bevel gear 52 to rotate, and the bevel gear 52 drives the bevel gear plate 53 to rotate, and drives the transmission gear 54 to rotate synchronously. At the same time, the transmission gear 54 drives the connecting gear 55 to rotate synchronously. Then, the connecting gear 55 drives the transmission gear 54 on the other side to rotate, and the transmission gears 54 on both sides drive the second transmission rod 6 to rotate synchronously, and the second transmission rod 6 drives the support tube 41 to rotate synchronously, adjusting the air outlet direction. Reasonable adjustment of the air outlet direction can directly guide the hot air to the area that needs to be heated, reduce the ineffective loss of hot air in the air, thereby reducing energy consumption and improving the utilization rate of thermal energy; S3. During air discharge, the electric push rod 42 uses the support tube 41 as the stress point to drive the transmission ring 43 to move along the outside of the support tube 41. At the same time, the transmission ring 43 uses the limit rod 44 to drive the guide plate 45 to rotate around the connection point between the guide plate 45 and the support tube 41, thereby adjusting the size of the air outlet. This adjusts the airflow pressure and optimizes the flow rate and flow rate of the hot air. By flexibly adjusting the size of the air outlet, the airflow can be evenly distributed, improving the uniformity of paper drying, avoiding local overdrying or overwetting, and improving drying efficiency. Precise airflow control not only reduces energy consumption and maximizes thermal energy utilization, but also ensures the quality and consistency of the final product, significantly improving production efficiency and hot air utilization. S4. The hot air flow is blown to the surface of the paper to be dried, and the moisture on the paper is dried by the hot air, and the moisture is carried out to the outside by the air flow. After the paper is dried, the first motor 24 stops driving, and the exhaust fan 71 is used to extract the air with moisture inside the equipment cover 1 and discharge it into the confluence cover 72, and then it is transported into the confluence joint 3 through the connecting pipe 73. When the gas in the confluence joint 3 is transported into the support cover 22, the gas passes through the second fan blade 32 and drives the second fan blade 32 to rotate. Then, the second fan blade 32 is used to drive the first transmission rod 72 to rotate the second fan blade 32. 33 drives the scraper 34 to clean the filtering surface at the top of the dust filter 27, which can effectively remove moisture and impurities inside the equipment cover 1, keep the air clean, and improve the dryness of the working environment. At the same time, the second fan blade 32 drives the scraper 34 to clean the dust filter 27, ensuring smooth airflow, preventing dust accumulation, extending the service life of the equipment and improving operating efficiency. The cleaned dust filter 27 maintains smooth airflow, helps to improve the distribution effect of hot air, and ensures that the paper is dried evenly. By reducing airflow obstruction, this method not only improves the utilization rate of thermal energy, but also reduces energy consumption, ensuring the efficient operation of the equipment and the quality of the final product.

10. A hot air distribution method for a low energy consumption hot air hood for a high speed paper machine, characterized in that: The steps include: S1. The first motor (24) drives the first fan blade (25) to rotate, thereby drawing in external air through the first through hole (23). During the process, the air is filtered by the dust filter (27). The air is then transported to the bottom through the first fan blade (25) and heated through the gaps between the heating wires (28). The air then enters the diversion chamber (13) for diversion, so that the air evenly enters each diversion hole (14). The air is then transported into the corrugated hose (4) through the diversion hole (14), and then transported out through the support tube (41) to dry the paper at the bottom. During S2, the second motor (51) drives the helical gear (52) to rotate, and the helical gear (52) drives the helical gear plate (53) to rotate, and drives the transmission gear (54) to rotate synchronously, and the transmission gear (54) drives the connecting gear (55) to rotate synchronously, and then the connecting gear (55) drives the transmission gear (54) on the other side to rotate, and the transmission gears (54) on both sides drive the second transmission rod (6) to rotate synchronously, and the second transmission rod (6) drives the support tube (41) to rotate synchronously, so as to adjust the air outlet direction; S3. When the air is discharged, the electric push rod (42) drives the transmission ring (43) to move along the outer side of the support tube (41) with the support tube (41) as the stress point. At the same time, the transmission ring (43) drives the guide plate (45) to rotate around the connection point between the guide plate (45) and the support tube (41) by using the limit rod (44), thereby adjusting the size of the air outlet and thus adjusting the air flow pressure; S4. The hot air flow is blown to the surface of the paper to be dried, and the moisture on the paper is dried by the hot air, and the moisture is carried out to the outside by the air flow. After the paper is dried, the first motor (24) stops driving, and the exhaust fan (71) is used to extract the air with moisture inside the equipment cover (1) and discharge it into the confluence cover (72), and then transported into the confluence joint (3) through the connecting pipe (73). When the gas in the confluence joint (3) is transported into the support cover (22), the gas passes through the second fan blade (32) and drives the second fan blade (32) to rotate. Then, the scraper (34) is driven by the first transmission rod (33) through the second fan blade (32) to clean the filter surface on the top of the dust filter (27).
