[0023] In this technical solution, the air supply hose 43 in the drying mechanism 4 of this device is installed below the material conveying network pipe 3 through the slot 42 on the connecting ring 41. Therefore, the hot air sprayed out of the air outlet 47 in the air supply hose 43 will directly act on the plastic particles inside the material conveying network pipe 3 without any obstruction, thus ensuring the drying effect of this device on the plastic particles.

[0024] In some technical solutions, the feeding hopper 2 includes a hopper body 21, a through groove 22 and a baffle plate 23. The hopper body 21 is inserted into and installed on the upper wall of the drying cylinder 1. The side wall of the hopper body 21 is provided with a through groove 22, and the baffle plate 23 is slidably installed in the through groove 22.

[0025] In this technical solution, a baffle plate 23 is also inserted into the side wall of the feed hopper 2. The baffle plate 23 can block the discharge end below the hopper body 21, thereby controlling the feeding speed of plastic particles in the feed hopper 2 and preventing the accumulation of plastic particles in the conveying network pipe 3.

[0026] In some technical solutions, the lower wall of the drying cylinder 1 is equipped with support feet 5, and the lower wall of the drying cylinder 1 is provided with a discharge hole 6. The end of the conveying mesh pipe 3 away from the feed hopper 2 is inserted into the discharge hole 6.

[0031] In this technical solution, the height of the support leg 5 in this device can be adjusted so that the height of this device can be adaptively adjusted according to the height of the external storage box, ensuring that the storage box can be placed below the drying cylinder 1.

[0032] Working principle: First, move the baffle plate 23 on the side wall of the feed hopper 2 to the appropriate position. Then, start the heating wire 45 and the fan 46 in the drying mechanism 4. Then, place the plastic granules to be dried into the feed hopper 2. The plastic granules will then enter the conveying mesh pipe 3 through the feed hopper 2. At this time, the fan 46 blows into the air inlet trough 44. The heating wire 45 heats the air. Then, the hot air enters the air conveying hose 43 and is discharged through the air outlet 47. It directly acts on the plastic granules inside the conveying mesh pipe 3 without any obstruction, thus ensuring the drying effect of this device on the plastic granules.

[0033] After the plastic granules move to the end of the conveying mesh 3, they will be discharged through the discharge hole 6 and fall into the external storage box.
