DETAILED DESCRIPTION OF THE EMBODIMENTS

[0021] The following further describes the embodiments of the present utility model in conjunction with the accompanying drawings and embodiments. The following embodiments are used to illustrate the present utility model, but cannot be used to limit the scope of the present utility model.

[0022] As Figure 1 shown, a sorting device for plastic pellets includes a sorting barrel 1 and an anti-blocking component 5. A sorting net 4 is arranged inside the sorting barrel 1. The end of the sorting barrel 1 is driven by a motor to rotate in the limit sleeve 2, so that the plastic pellets can be better sorted by the sorting net 4 during the movement in the sorting barrel 1. A limit sleeve 2 is arranged outside the end of the sorting barrel 1, and the sorting barrel 1 is rotationally connected to the limit sleeve 2. An opening and closing component 3 for opening and closing is arranged on the side of the limit sleeve 2, and the number of the opening and closing components 3 is three. The opening and closing component 3 includes a hydraulic rod 301 and a cover 302. The stretching and retracting of the three hydraulic rods 301 respectively control the opening and closing of the corresponding connected covers 302. The three different covers 302 correspond to different sorting gaps and play a role in blocking the sorted plastic pellets. And the output end of the hydraulic rod 301 is installed with the cover 302.

[0023] As Figure 2 shown, the anti-blocking component 5 for preventing blockage in the sorting of plastic pellets is arranged outside the sorting net 4. The sorting net 4 sorts the plastic pellets in the sorting barrel 1. And the anti-blocking component 5 includes a mounting plate 501, a roller 502, a rotating ring 503, a bracket 504, a connecting plate 505 and an anti-blocking roller 506. The upper end of the mounting plate 501 is installed with the roller 502 through a motor. The mounting plate 501 is used for the installation of the roller 502. And a rotating ring 503 is arranged on the side of the roller 502. The roller 502 drives the rotating ring 503 to rotate inside the sorting barrel 1 under the drive of the motor. A bracket 504 is arranged behind the rotating ring 503. And the inner side of the rotating ring 503 is connected with the connecting plate 505. The end of the connecting plate 505 is connected with the anti-blocking roller 506. The number of the anti-blocking rollers 506 is two. The connecting plate 505 and the anti-blocking roller 506 roll outside the sorting net 4 along with the rotation of the rotating ring 503, cleaning the plastic pellets stuck in the sorting net 4 to avoid affecting the sorting effect due to blockage. And the roller 502 and the sorting net 4 are arranged in parallel.

[0024] As Figure 3 shown, a control frame 6 is arranged behind the limit sleeve 2. The control frame 6 is used for supporting the limit sleeve 2. And the shape of the control frame 6 is a U shape. The middle part of the side of the control frame 6 is installed with a rotating frame 7 through a rotating shaft. And hydraulic rods 8 are installed at the upper and lower ends of the side of the control frame 6. The number of the hydraulic rods 8 is two. The stretching and retracting of the two groups of hydraulic rods 8 adjust the angle of the sorting barrel 1 and the limit sleeve 2, making it tilt downward for easy feeding and tilt upward for easy feeding. The rotating frame 7 rotates accordingly. And the fixed end of the hydraulic rod 8 is installed with a support frame 9.

[0025] In summary, for this sorting device for plastic pellets, first, according to Figure 1-Figure 3 , when adding materials, the upper hydraulic rod 28 is controlled to contract and the lower hydraulic rod 28 is extended, so that the sorting barrel 1 is tilted upward, and the plastic pellets to be sorted are poured into the sorting net 4 in the middle of the sorting barrel 1. The hydraulic rod 1 301 is controlled to contract again to cover the end of the sorting barrel 1 with the cover 302. After loading, the sorting barrel 1 is reset to a horizontal state, and the motor at the end of the sorting barrel 1 is turned on to rotate the limit sleeve 2, so that the plastic pellets can move better in the sorting barrel 1 and be sorted by the sorting net 4. The sorting net 4 sorts the plastic pellets in the sorting barrel 1. At the same time, the roller 502 is driven by the motor to drive the rotating ring 503 to rotate inside the sorting barrel 1. The connecting plate 505 and the anti-blocking roller 506 roll on the outside of the sorting net 4 as the rotating ring 503 rotates, which cleans the plastic particles stuck in the sorting net 4 to avoid blockage and affect the sorting. After the sorting is completed, the upper hydraulic rod 28 is controlled to extend and the lower hydraulic rod 28 is controlled to contract, so that the sorting barrel 1 tilts downward, and the middle cover 302 connected to the hydraulic rod 1 301 is controlled to extend to pour out the sorted plastic material in the middle, and then the outer covers 302 are opened in sequence to complete the unloading.
