The surface fixed connection has two groups of symmetrical side plate 2 of setting of base 1, two groups of side plate 2 are fixedly connected with screening bucket 3 through fixed connection between the two, and two groups of side plate 2 are used for supporting and fixing screening bucket 3, make screening bucket 3 be in the state of suspension. The top fixed connection has feeding port 31 of screening bucket 3, and the feeding port 31 is located the top of screening bucket 3, is used to the inside of screening bucket 3 is inputed with the plastic particle of screening,
[0033] Refer to Figure 2 - Figure 3 The inside of screening bucket 3 is provided with screening assembly 4, and screening assembly 4 is used for screening plastic particles. Screening assembly 4 includes a rotating shaft 41, which penetrates and is rotatably connected to the end face of the screening bucket 3. The rotating shaft 41 penetrates and is rotatably connected to the side wall of the side plate 2. The outer wall of the rotating shaft 41 is hinged with multiple groups of arrayed sieve plates 42. The rotating shaft 41 is used to rotate the multiple groups of sieve plates 42, thereby screening the plastic particles in the interior of the screening bucket 3. The sizes of the holes of the multiple groups of sieve plates 42 decrease in turn. Since the sizes of the holes of the multiple groups of sieve plates 42 are different, the screening requirements of plastic particles of different sizes can be met. The rotating sieve plates 42 separate the particles into different grades through continuous screening. An arc protrusion 43 is fixedly connected to the inner wall of the screening bucket 3. The sieve plates 42 contact the arc protrusion 43 during rotation, thereby causing the screening bucket 3 to vibrate and preventing the sieve plates 42 from being blocked. A motor 44 is fixedly connected to the side wall of the side plate 2. The output shaft of the motor 44 is fixedly connected to the end of the rotating shaft 41. The motor 44 provides power for the rotation of the rotating shaft 41 through its output shaft.
[0034] Refer to Figure 2 - Figure 3 A plurality of sieve plates 42 are provided with an elastic support assembly 5. The elastic support assembly 5 includes a sleeve rod 51, which is hinged to the surface of the sieve plate 42. A sliding rod 52 is slidably connected to the inside of the sleeve rod 51. The end of the sliding rod 52 is hinged to the surface of the sieve plate 42. The sliding rod 52 is elastically connected to the inside of the sleeve rod 51 by a return spring 53. The return spring 53 provides elastic support between the sieve plates 42. After the sieve plates 42 contact the arc protrusion 43, they can start to reset. The sieve plates 42 can adapt to different impacts and vibrations during the screening process, thereby preventing damage or deformation due to excessive stress.

The limiting plate 71 is in contact with the bottom surface of the blocking plate 6 through rotation, thereby fixing the blocking plate 6 and making the blocking plate 6 block the discharge port 32.
[0036] Working principle: when the plastic particles need to be screened, the plastic particles to be screened are first put into the inside of the screening barrel 3 through the feeding port 31. Then the motor 44 is started, and the output shaft of the motor 44 drives the rotating shaft 41 to rotate, and the rotation of the rotating shaft 41 drives the multiple sets of sieve plates 42 to rotate. Since the sizes of the holes of the multiple sets of sieve plates 42 decrease in turn, different sizes of plastic particles can be screened, and the particles can be separated into different grades. During the screening process, the sieve plates 42 are in contact with the arc-shaped protruding portions 43, so that the screening barrel 3 is shaken to prevent the sieve plates 42 from being blocked. At the same time, the elastic support assembly 5 provides elastic support between the sieve plates 42, so that the sieve plates 42 can adapt to different impacts and vibrations, and avoid damage or deformation due to excessive stress. When the screening is completed, the limiting plate 71 is separated from the bottom surface of the blocking plate 6 by rotating the limiting plate 71, and then the blocking plate 6 is opened to discharge the plastic particles. The device has a simple structure and is easy to operate, can realize the screening of plastic particles of different sizes, and improves the screening efficiency and quality.
