[0017] The technical solutions in the embodiments of the present invention are described clearly and completely below. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0018] See also Figure 1 , the utility model embodiment includes:

[0019] like Figure 1 The automatic drying device for plastic particles shown includes: a sealed box 1, a chain 11, a brush plate 15, an air distribution plate 12, a sieve plate 7 and a hot air blower 2. An air storage block 14 is arranged at the bottom of the sealed box 1. The air distribution plate 12 is horizontally arranged on the top opening of the air storage block 14. The air outlet of the hot air blower 2 is connected to the inner cavity of the air storage block 14, and hot air is delivered into the air storage block 14 through the hot air blower 2.

[0020] The chain 11 is rotatably arranged in the sealing box 1 and is located above the air distribution plate 12. A sprocket 16 for rolling support of the chain is arranged in the sealing box 1. A motor for driving the sprocket 16 to rotate is arranged on the outside of the sealing box 1. The axle of the sprocket 16 extends to the outside of the sealing box 1 and is connected to the motor through a coupling to realize the rotation drive of the sprocket 16.

[0021] Brush plates 15 are arranged on the chain 11 at intervals, and steel wires 13 are arranged on the brush plates 15 at intervals, so that the brush plates 15 and the steel wires 13 can run with the chain 11. A first material guide plate 3 extending obliquely upward from the rear end of the air distribution plate 12 is arranged in the sealed box 1, and a feed pipe 5 pointing downward to the first material guide plate 3 is arranged on the top of the sealed box 1. Plastic particles fall downward into the first material guide plate 3 through the feed pipe 5, and are sent to the air distribution plate 12 through the first material guide plate 3. The steel wires 13 on the brush plates 15 are used to push the plastic particles to roll forward in batches.

[0022] In this embodiment, the air distribution plate 12 is densely covered with blowing holes. The hot air sent into the air storage block 14 by the hot air blower 2, on the one hand, increases the temperature of the air distribution plate 12 and transfers the heat to the plastic particles above the air distribution plate 12; on the other hand, air is blown upward through the blowing holes to dry the plastic particles passing above the air distribution plate 12, thereby achieving drying of the plastic particles during the rolling process on the air distribution plate 12.

[0023] A second material guide plate 9 extending obliquely downward from the front end of the air distribution plate 12 is provided in the sealing box 1. A discharge pipe 10 located below the front end of the second material guide plate 9 is provided at the bottom of the sealing box 1. The plastic particles rolling on the air distribution plate 12 slide down through the second material guide plate 9 and are discharged by the discharge pipe 10 to realize automatic unloading.

[0024] In order to prevent the plastic particles from flying upward, an air collecting hood 8 located above the chain 11 is provided in the sealed box 1, and the sieve plate 7 is horizontally arranged on the bottom inlet of the air collecting hood 8 to prevent the plastic particles from entering the air collecting hood 8. In this embodiment, an exhaust fan 6 connected to the air collecting hood 8 is provided on the sealed box 1 to exhaust the air from the air collecting hood 8 and discharge the moisture in the sealed box 1. During the exhaust fan 6, the sieve plate 7 generates suction, which will absorb some plastic particles. The plastic particles on the bottom surface of the sieve plate 7 can be cleaned by the rotation of the steel wire 13, thereby avoiding the problem of the sieve plate 7 being blocked.

[0025] In this embodiment, the hot air blower 2 is arranged in the sealed box 1 and is located below the first guide plate 3, and has a compact structure. A window corresponding to the air inlet of the hot air blower 2 is arranged on the side wall of the sealed box 1, so that external dry air can enter the hot air blower 2, and a dustproof net 4 is arranged in the window to filter the air.

[0026] In summary, the utility model discloses an automatic drying device for plastic particles, which pushes the plastic particles through the rotation of the brush plate 15 and the steel wire 13, and performs air blowing drying under the action of the air distribution plate 12, thereby improving the drying efficiency and the convenience of loading and unloading. There is no need to stop the machine during the loading and unloading process, which improves the production efficiency. In addition, the device has a high degree of automation, which is conducive to the establishment of an automatic production line for plastic particles.

[0027] The above are only embodiments of the present invention, and are not intended to limit the patent scope of the present invention.
