A second inclined plate 9 is fixedly connected to the inner wall of the body 3 near the first inclined plate 8. Multiple air vents are provided on the surfaces of the first inclined plate 8 and the second inclined plate 9. The plastic granules are dried more evenly by the action of the first inclined plate 8 and the second inclined plate 9. Two feeding plates 10 are symmetrically fixedly connected inside the body 3 near the second inclined plate 9 to facilitate the free fall of plastic granules. Baffles 11 are fixedly connected to the bottom of the two feeding plates 10. The bottom of the two baffles 11 is fixedly connected to the bottom of the inner wall of the body 3. A discharge port 12 is provided at the bottom of the body 3 to facilitate the discharge of dried plastic granules. A control component for controlling the discharge of plastic granules is provided below the discharge port 12 of the body 3. Two vertical pipes 5 are provided on both sides of the outer surface of the body 3. A first drying pipe 15 and a second drying pipe 16 are fixedly connected to the surfaces of the two vertical pipes 5 respectively. One end of the first drying pipe 15 and the second drying pipe 16 are both installed through the interior of the body 3.
[0022] The first drying tube 15 and the second drying tube 16 are located below the first inclined plate 8 and the second inclined plate 9, respectively. The first drying tube 15 and the second drying tube 16 facilitate the drying of plastic granules falling from the first inclined plate 8 and the second inclined plate 9. A blower 13 is fixedly connected to one side of the machine body 3. A drying chamber 14 is fixedly connected to the surface of the machine body 3 near the blower 13. A frame 23 is fixedly connected inside the drying chamber 14, and a heating mesh 24 is fixedly installed on the inner wall of the frame 23. Two conduits 4 are fixedly connected between the drying chamber 14 and the two vertical tubes 5, with both ends of the two conduits 4 extending through and into the interior of the vertical tubes 5 and the drying chamber 14, respectively. The machine 13 and the drying chamber 14 are connected by a connecting pipe. The heat generated inside the drying chamber 14 can be blown out by the operation of the blower 13, which is very convenient. The top of the machine body 3 is provided with a feeding port 7. The top of the machine body 3 near the feeding port 7 is fixedly connected to the feeding bin 6. The feeding port 7 and the feeding bin 6 make it easy to add the plastic granules to be dried. The bottom of the machine body 3 is fixedly connected with support legs 2 on all four sides. The support legs 2 make it easy to support the machine and ensure that it is more stable during use. The surface of the first drying tube 15 and the second drying tube 16 are provided with multiple through holes. The through holes facilitate the rapid discharge of the generated hot air.
[0023] like Figure 3 As shown, the control assembly includes two vertical plates 1, with a bidirectional screw 18 rotatably connected between them. Two drive blocks 19 are threadedly connected to the outside of the bidirectional screw 18, and a sealing plate 22 is fixedly connected to the top of each drive block 19. The two sealing plates 22 are located below the discharge port 12. Driven by the bidirectional screw 18, the drive blocks 19 can be moved, facilitating the movement of the sealing plates 22. Two sets of sliding grooves 20 are symmetrically provided at the bottom of the machine body 3. Sliding sliders 17 are slidably connected inside each set of sliding grooves 20. The top of each slider 17 is fixedly connected to the top of the corresponding sealing plate 22. The sliding of the sliders 17 within the sliding grooves 20 improves the stability of the sealing plates 22 during opening and closing. A motor 21 is fixedly connected to one side of the surface of one of the vertical plates 1. The output end of the motor 21 passes through the vertical plate 1 and is fixedly connected to one end of the bidirectional screw 18. The motor 21 drives the bidirectional screw 18 to rotate, making operation more convenient.
[0024] In use, plastic granules are added from the feed hopper 6 and enter the machine body 3 through the feeding port 7. At the same time, the blower 13 is started and the heating mesh 24 is turned on. Hot air is sent into the first drying tube 15 and the second drying tube 16 through the guide tube 4 and the vertical pipe 5. The hot air is discharged through the through hole, which dries the plastic granules falling onto the first inclined plate 8 and the second inclined plate 9. The dried plastic granules fall freely through the feeding plate 10. The motor 21 is turned on, and the motor 21 drives the bidirectional screw 18 to rotate. After the bidirectional screw 18 rotates, it drives the drive block 19 to move. After the drive block 19 moves, it drives the sealing plate 22 to move, which facilitates discharge through the discharge port 12. It is very convenient and more practical.
