[0032] Working Principle: With the auxiliary drying mechanism 8, the plastic granules, which may contain some moisture after granulation, are fed into the rotating drum 5 through the feed hopper 13. Then, the heating wire in the hot air drying mechanism 12 is activated, and the fan in the hot air drying mechanism 12 blows hot air into the rotating drum 5. Subsequently, the drive mechanism 7 is activated, driving the transmission sprocket 6 to rotate. The transmission sprocket 6 drives the rotating drum 5 to rotate simultaneously. As the rotating drum 5 rotates, the roller connecting sleeve 4 rotates on the roller support frame 3. Simultaneously, the DC motor 82 inside the fixed housing 81 is activated, driving the carbon steel eccentric wheel 83 to rotate through the output shaft of the DC motor 82. Each rotation of the carbon steel eccentric wheel 83 lifts the lifting plate 84 once. After the lifting plate 84 is lifted, it moves the lifting connecting rod 88, causing the impact rod 89 at the top of the lifting connecting rod 88 to strike the rotating drum 5. The impact rod 89 then resets under gravity, repeatedly striking the outside of the rotating drum 5 to reduce the amount of plastic adhering to the rotating drum during the drying process. The condition of the inner wall of body 5 helps to disperse the agglomerated plastic particles. Through heating and ventilation, the moisture on the outside of the plastic particles is effectively removed, ensuring the dryness of the plastic particles and facilitating the drying process. With the support connection mechanism 9, the hopper support seat 10 can support the bottom of the hopper body 11. At this time, one side of the hopper support seat 10 is fixedly connected to the mounting plate 1.

One end of the movable reinforcing plate 94 on the outside of the anti-detachment guide slider 93 is movably inserted into the hopper support seat 10. The corresponding surface of the fixed mounting plate 96 on the top of the movable reinforcing plate 94 is attached to the outside of the hopper support seat 10. Then, the reinforcing threaded column 97 is threadedly connected to the hopper support seat 10, which can easily fix the position of the movable reinforcing plate 94 and reinforce the installation part on the outside of the hopper support seat 10 through the movable reinforcing plate 94, improving the connection stability of the hopper support seat 10 and helping to ensure the stability of the assembly structure of the hopper body 11.
