[0021] like Figure 1-Figure 2 As shown, a plastic pellet screening device includes an outer shell 1, a screening component 3 and a screening auxiliary component 6. A feed port 2 is provided on the upper left side of the outer shell 1, and a discharge frame 7 is connected to the lower right side of the outer shell 1. The discharge frame 7 and the outer shell 1 are communicated with each other, and a movable baffle 8 is installed on one side of the inner part of the discharge frame 7 for sliding up and down. Three partition plates 4 are fixed at equal distances at the lower part of the inner part of the outer shell 1, and a lower hopper 5 is installed between adjacent partition plates 4, and four lower hoppers 5 are provided; the feed port 2 is convenient for feeding, and the movable baffle 8 can be movably pulled and pulled to facilitate the discharge of unscreened plastic pellets through the discharge frame 7. The four lower hoppers 5 correspond to four screens 303 with different mesh diameters, so as to facilitate the screening of plastic pellets of different sizes and the corresponding material reception at one time.

[0022] like Figure 1-Figure 2As shown, the interior of the outer shell 1 is equipped with a screening component 3, and the screening component 3 includes a screen frame 301, a chute 302 and a screen 303. Three chute 302 are opened inside the screen frame 301, and four screens 303 are installed on the inner side of the screen frame 301 separated by the chute 302. The screens 303 and the screens 303 are inclined, and the screens 303 are connected to the inner wall of the outer shell 1 for upward and downward sliding. The mesh diameters of the four screens 303 increase from top to bottom. The screening component 3 also includes a mounting plate 304 and a vibration motor 306. The side wall of the outer shell 1 is fixed with a mounting plate 304, and the mounting plate 304 is located below the screen frame 301. Below one side of the screen frame 301 A vibration motor 306 is also installed, and the screening assembly 3 also includes a telescopic spring 305. The telescopic spring 305 is connected to the top of the mounting plate 304 at equal distances, and the top of the telescopic spring 305 is fixedly connected to the bottom surface of the screen frame 301; the mesh diameters of the four screens 303 increase from top to bottom, and at the same time, the screens 303 and 303 are inclined structures to facilitate the remaining plastic particles after screening to be discharged to the next screen 303 position under the action of gravity, so as to facilitate classification and screening, and the vibration of the screen frame 301 and the screen 303 is facilitated by the vibration motor 306. At the same time, the telescopic spring 305 can reciprocate and telescope to cooperate with the vibration of the screen 303 to promote screening efficiency.

[0023] like Figure 2-Figure 3 As shown, a screening auxiliary component 6 is installed inside the chute 302, and the screening auxiliary component 6 includes a baffle plate 601, a limit plate 602 and a rack 603. The baffle plate 601 is installed to slide up and down inside the chute 302, and the limit plate 602 is fixed in the top middle of the baffle plate 601, and a rack 603 is fixed in the middle of the right side of the baffle plate 601. The top surface of the baffle plate 601 is an inclined surface, and the limit plate 602 is an inclined structure, and the limit plate 602 has the same inclination amplitude as the screen frame 301. The screening auxiliary component 6 also includes a micro motor 604 and a gear 605. A micro motor 604 is installed above the partition plate 4, and the output shaft of the micro motor 604 is fixed to the bottom of the partition plate 4.

[0024] In summary, if Figure 1-Figure 3As shown, when the plastic pellet screening device is used, the material can first be fed through the feed port 2, and then the vibration motor 306 is used to promote the vibration of the screen frame 301 and the screen 303. At the same time, the telescopic spring 305 can reciprocate and telescope to cooperate with the vibration of the screen 303 to promote screening efficiency. At this time, the three baffle plates 601 can block the plastic pellets on the screen 303 to prevent some plastic pellets that are not fully screened from being directly discharged to the position of the screen 303 with a larger diameter, so that the first screen 303 can fully screen this part of the plastic pellets. Then, the micro motor 604 and the output shaft drive the rotation of the gear 605, thereby driving the rack 603 and the baffle plate 601 to move up and down, and the top surface of the baffle plate 601 is an inclined surface. The top surface of the baffle plate 601 can be moved down to the chute 302 to cooperate with the rolling of the plastic pellets. At this time, the inclined limit plate 602 can be located on the upper side of the screen 303 to prevent the baffle plate 601 from falling out of the chute 302. Then, the remaining plastic pellets after screening are discharged to the next screen 303 position under the action of gravity. Similarly, continuous screening can be carried out for classification and screening. The mesh diameters of the four screens 303 increase from top to bottom. At the same time, the four discharge hoppers 5 correspond to four screens 303 with different mesh diameters, which can screen plastic pellets of different sizes and receive materials accordingly. Finally, the movable baffle 8 can be pulled and movably to allow the discharge frame 7 to discharge the unscreened plastic pellets, thus completing the use process of the plastic pellet screening device.
