The inner cavity of the second drying box 7 is connected with the inner cavity of the first drying box 1 through the discharge port 11. The discharge port 13 is located at the upper end of the conveyor belt 10, and the guide plate 12 is set to an inclined state, and the number of the guide plates 12 is multiple groups. Through the mutual cooperation of the guide plate 12, the fan 8, and the heat dryer 9 in the second drying box 7, the second drying of the plastic particles is realized. The plastic particles enter the second drying box 7 through the discharge port 11, and then the plastic particles fall evenly in sequence through the inclination of the guide plate 12. At the same time, the heat dryer 9 cooperates with the fan 8 to dry, thereby improving the efficiency of drying the plastic particles. Through the conveyor belt 10, it is convenient to transport the dried plastic particles.
[0023] In this embodiment, Figure 3-Figure 4 As shown, a driving gear 14 is movably connected to one side of the driving motor 6, and a driven gear 15 is movably connected to the outer wall of the driving gear 14, and a stirring shaft 16 is fixedly connected to one side of the driven gear 15, and a stirring blade 17 is fixedly installed on the outer wall of the stirring shaft 16.

[0024] Working principle:
[0025] The first drying of the plastic particles is achieved by the cooperation of the drive motor 6, the driving gear 14, the driven gear 15, the stirring shaft 16, the stirring blade 17, the blower 3, the conveying air duct 18, the first air nozzle 19, and the second air nozzle 20. The plastic particles are introduced into the first drying box 1 through the feed hopper 2, and then the wind source is input into the conveying air duct 18 through the blower 3. The plastic particles are respectively drawn from the first air nozzle 19 and the second air nozzle 20 into the first drying box 1 for air drying. At the same time, the stirring shaft 16 is driven to rotate by the drive motor 6, so that the stirring blade 17 stirs the plastic particles in the first drying box 1 so that the plastic particles are evenly mixed. The staggered design of the two sets of air nozzles increases the range of air outlet, which solves the problem of plastic particles piling up in one place. The plastic particles inside the drying box 7 are not easy to dry, and the drying effect of the plastic particles close to the air outlet is better, but the drying effect of the plastic particles far from the air outlet is not very good, which leads to the problem that the plastic particles are not dried thoroughly enough, and the unevenly dried plastic particles will have a certain degree of impact on the quality when manufacturing plastic products. Through the cooperation of the guide plate 12, the fan 8, and the heat dryer 9 in the second drying box 7, the second drying of the plastic particles is achieved. The plastic particles enter the second drying box 7 through the discharge port 11, and then the plastic particles are evenly dropped in sequence through the inclination of the guide plate 12. At the same time, the heat dryer 9 cooperates with the fan 8 to dry, thereby improving the drying efficiency of the plastic particles. The conveyor belt 10 is used to facilitate the transportation of the dried plastic particles.
[0026] Based on the embodiments of the present utility model, all other embodiments obtained by ordinary technicians in the field without making any creative work shall fall within the scope of protection of the present utility model.
