A plurality of mounting members are connected to the upper sides of the front and rear parts of the air inlet chamber 3. A protective net is installed between the mounting members. The protective assembly 6 also includes a scraping mechanism 7. The scraping mechanism 7 includes a driving assembly 71, a screw rod 72, a guide rod 73 and a scraper 74. The left part of the lower part of the drying chamber 2 is rotatably connected to a screw rod 72 for auxiliary movement. The right part of the lower part of the drying chamber 2 is connected to a guide rod 73 for sliding guidance. The screw rod 72 is threadedly connected to a guide rod for conveying. A scraper 74 is used to scrape and turn over the plastic particles on the component 1. The right part of the scraper 74 is slidably connected to the guide rod 73. A driving component 71 for driving the screw rod 72 to rotate is connected between the front right part of the left part of the drying bin 2 and the screw rod 72. The driving component 71 includes a mounting seat, a servo motor, a pulley and a transmission belt.

The servo motor output shaft and the front part of the screw rod 72 are both connected with pulleys, and a transmission belt is wound between the pulleys.

[0020] When drying plastic particles, the device can be used. It should be noted that the heating rod 4 and the guide component 5 are first started, so that the guide component 5 guides the wind in the air inlet bin 3, and the heating rod 4 heats and dries the wind in the air inlet bin 3, so that the hot air heats and dries the drying bin 2, and then the plastic particles to be dried are laid flat on the upper middle side of the conveying component 1, so that the conveying component 1 conveys the plastic particles, and the hot air dries the plastic particles. Then the driving component 71 is started, so that the driving component 71 drives the screw rod 72 to rotate back and forth continuously, and the scraper 74 slides back and forth along the guide rod 73 to flip the plastic particles on the conveying component 1. At this time, the hot air in the drying bin 2 can dry the flipped plastic particles more evenly, and then the dried plastic particles can be taken out from the upper rear side of the conveying component 1. In summary, through the cooperation between the screw rod 72 and the scraper 74, the plastic particles on the conveying component 1 are flipped and dried, so that the plastic particles are heated evenly during the drying process, and the drying effect is better.

The rear sides of the left and right parts of the conveying assembly 1 are both connected to the fixing members 81, and the collecting frames 82 for collecting the dried plastic particles are connected between the fixing members 81 by bolts.

[0022] It should be noted that when the conveying component 1 conveys the dried plastic particles, the dried plastic particles fall along the rear of the conveying component 1 into the collecting frame 82 for cooling and unified collection. When the plastic particles are dried, the plastic particles can be uniformly taken out from the collecting frame 82. In summary, the plastic particles are uniformly cooled and collected by the collecting frame 82, which facilitates the collection of the plastic particles and improves the convenience of collection.
