[0002] When plastic particles are processed by injection molding or extrusion, the processing temperature is usually high. After injection molding, some moisture generated by the reaction or moisture used in cooling, cleaning and other processes will remain in the plastic particles. If this residual moisture is not removed in time, it will have an adverse effect on the quality of the plastic particles.

[0044] The working process and principle of this application are as follows:

[0045] When in use, the feeding mechanism is used to add the plastic particles to be dried into the inner barrel 11 through the feed pipe 16, and the servo motor 12 is started to drive the spur gear to rotate, and the spur gear drives the outer gear ring and the inner barrel 11 inside it to rotate. When the inner barrel 11 rotates, it drives the plastic particles inside it to make a circular motion for drying, and the spun water enters the fixed outer barrel 1 through the water outlet hole of the inner barrel 11, and then the water is discharged through the water outlet 13. After the water in the plastic particles is dried, the electric cylinder 18 is started to drive the motor frame 19 to move upward. At this time, the sealing plate 22 moves upward to open the discharge pipe 14, and the stepper motor 20 is started. The stepper motor 20 drives the sealing plate 22 and the spiral conveyor belt 23 to rotate. When the spiral conveyor belt 23 rotates, the plastic particles in the inner barrel 11 are transported to the shell 24 to prevent the plastic particles from being blocked in the inner barrel 11;

[0046] The plastic particles enter the shell 24 and accumulate on the top of the conveyor belt 32. The stepper motor 2 31 is started to drive the roller to rotate. The roller drives the outer conveyor belt 32 to rotate to transport the plastic particles. When the plastic particles pass under the push plate 29, they are scraped flat by the push plate 29, so that they are spread flat on the top of the conveyor belt 32. The ion fan 33 and the electric heating wire are started. The ion fan 33 transports the ionized ions and wind to the air outlet pipe 34. The wind is heated by the electric heating wire. The hot wind with ions is blown into the shell 24 through the air outlet pipe 34, and then flows upward through the opening of the conveyor belt 32. After passing through the bucket-shaped bin 25 and the conveying pipe 26, it is discharged through the air outlet 27, so that the plastic particles spread on the top of the conveyor belt 32 are dried and static electricity is removed, thereby preventing the plastic particles from agglomerating during drying and affecting the drying effect;

[0047] The weight of the dried plastic particles is reduced and they are carried to the air outlet 27 by the wind. At this time, the wind is discharged through the air outlet 27, and the dried plastic particles fall into the equalizing bin 35 due to gravity. Then the stepper motor 38 is started to drive the spiral conveyor belt with shaft to rotate, so that the dried plastic particles in the equalizing bin 35 are evenly divided and packaged.

[0048] The above are only preferred specific implementation modes of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solutions and inventive concepts of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
