[0006] Furthermore: the number of grading plates is not less than three, and the material discharge port includes a first material discharge port, a second material discharge port and a third material discharge port, wherein the area of ​​the third material discharge port is 1.5-2 times the area of ​​the first material discharge port.

[0007] Furthermore, the width of the stirring plate increases progressively along the direction from the feed hopper to the discharge hopper, specifically including a first stirring plate, a second stirring plate, a third stirring plate, and a fourth stirring plate.

[0008] Furthermore, the stirring plates are evenly distributed within the same drying space, and the number of stirring plates near the feed hopper is greater than the number of stirring plates near the discharge hopper.

[0009] Furthermore: the upper end of the fixed bracket is fixed with an inclined receiving plate located directly below the strainer pipe, and the receiving plate has a suction hole that connects to the vacuum cleaner.

[0010] Furthermore, the discharge ports are symmetrically distributed on the grading plate.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-6 This utility model provides a technical solution: a drying device for wound plastic granules; specifically, it includes a fixed support 1, a drive motor 5 fixed at the upper end of the fixed support 1, a rotating rod 6 fixed at the output end of the drive motor 5 via a transmission belt, a mesh channel 2 fixed on the outside of the rotating rod 6, a feeding hopper 3 fixed on one side of the upper end of the mesh channel 2, and a discharging hopper 4 fixed on the outside of the lower end of the mesh channel 2; plastic granules are fed into the feeding hopper 3, a drying cylinder 11 is provided on the outside of the mesh channel 2, a connecting pipe network 15 is fixedly connected to the upper end of the drying cylinder 11, and a control cabinet 1 is fixed on the other side of the fixed support 1. 2. A heating cylinder 13 is provided with a blower 14 at the lower end of the heating cylinder 13. The blower 14 blows the hot air in the heating cylinder 13 into the pipe network 15, and then into the interior of the drying cylinder 11 through the pipe network 15. This is existing known technology and will not be described in detail here. A graded stirring mechanism is fixed on the outer wall of the rotating rod 6. The graded stirring mechanism moves the plastic particles step by step, thereby drying the plastic particles more thoroughly and improving the drying efficiency. At the same time, it can prevent the plastic particles from sticking to the mesh channel 2. The graded stirring mechanism can make the particles move and dry in stages, avoiding the particles sticking and not being fully dried, thus improving the drying efficiency.

[0022] The grading and mixing mechanism includes multiple grading plates 9, which divide the mesh channel 2 into multiple corresponding spaces. Through-hole discharge ports are provided at the symmetrical ends of the grading plates 9. The area of ​​the discharge ports gradually increases from the position of the feed hopper 3 to the position of the discharge hopper 4, namely the first discharge port 91, the second discharge port 92, and the third discharge port 93. When plastic particles enter from the position of the feed hopper 3, the clumped plastic particles cannot pass through the first discharge port 91. This allows the clumped plastic particles to be repeatedly agitated within the first space, improving the efficiency of dispersing clumps. In the second space, the remaining unseparated plastic particles are further agitated multiple times, and so on, until they move to the final space. When the plastic particles reach the lowest discharge hopper 4, they are dried and the particles are clearly separated.

[0023] A fixing ring 10 is fixed on the outer ring of the rotating rod 6, and a stirring plate is fixed on the outer ring of the fixing ring 10. The width of the stirring plate gradually increases from the position of the feed hopper 3 to the position of the discharge hopper 4. The stirring plate includes a first stirring plate 101, a second stirring plate 102, a third stirring plate 103, and a fourth stirring plate 104. Then, the plastic particles in the first space are stirred multiple times by the thinner first stirring plate 101, and there are multiple first stirring plates 101 with equal spacing. Similarly, the second stirring plate 102 is wider than the first stirring plate 101, and can be used to handle plastic particles with different adhesion and agglomeration. And so on. The fourth stirring plate 104 near the discharge hopper 4 can break up the particles and increase the drying contact area.

[0024] A receiving plate 7 is provided at the upper end of the fixed bracket 1. A suction hole 8 is provided on the receiving plate 7. The receiving plate 7 is inclined and located directly below the mesh channel 2. A vacuum cleaner can be installed at the lower end of the receiving plate 7. The port of the vacuum cleaner is connected to the suction hole 8. In this way, the debris generated when the plastic granules are stirred can be prevented from generating dust, thereby maintaining a healthy working environment.
