Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

[0025] Embodiment 1: Please refer to Figures 1-5, A screening device for plastic pigments, comprising a base 1 and a slope plate 2. The top of the base 1 is fixedly assembled with the slope plate 2. Brackets 3 are supported and fixed on the left side of the top of the slope plate 2 and the right side of the top of the base 1 respectively. A bushing 4 is fixed inside the bracket 3. A sieve plate 8 is arranged above the slope plate 2. Mounting seats 6 are welded on both sides of the sieve plate 8 respectively. A driven shaft 5 is fixedly connected to the left side of the mounting seat 6, and a driving shaft 9 is fixedly connected to the right side of the mounting seat 6. The driven shaft 5 and the driving shaft 9 are respectively movably sleeved inside the bushing 4. A feeding tray 16 is arranged on the right side of the slope plate 2. A variable-speed motor 24 is arranged behind the driving shaft 9. The output shaft of the variable-speed motor 24 is fixedly sleeved with a rotating shaft 23. A turntable 11 is fixedly sleeved outside the rotating shaft 23. A movable frame 10 is movably sleeved outside the turntable 11. A first gear 12 is fixedly sleeved at the front end of the rotating shaft 23. The bottom end of the first gear 12 is meshed with a second gear 13. A rotating rod 14 is fixedly connected to the bottom end of the second gear 13. A pushing frame 15 is fixedly connected to the bottom end of the rotating rod 14. A group of material openings 25 are arranged in the feeding tray 16. The material openings 25 are fan-shaped. The pushing frame 15 is cross-shaped. The pushing frame 15 rotates in contact with the feeding tray 16. The first gear 12 and the second gear 13 are of the same size. The first gear 12 and the second gear 13 are both bevel gears. The turntable 11 is a triangular plate, and its three sides are in contact with the inner side wall of the movable frame 10;

[0026] Specifically, as Figure 1 , Figure 3 , Figure 4 and Figure 5 shown, the oil-soluble pigment raw materials are put on the inclined sieve plate 8. The variable-speed motor 24 is started. The rotating shaft 23 drives the turntable 11 to rotate, thereby driving the turntable 11 to make a circular motion with the rotating shaft 23 as the center point, thereby pushing the movable frame 10 and the driving shaft 9 to perform a reciprocating linear motion in the horizontal direction. The high-frequency reciprocating swing forms a sieving motion, so as to separate large particles and debris, etc. The sieved raw materials roll from left to right at the sieve plate 8 and are collected in the collection box 19. The small particles and debris fall onto the slope plate 2 through the sieve holes of the sieve mesh 21 and roll to the feeding tray 16. The first gear 12 fixed at the front end of the rotating shaft 23 transmits torque to the second gear 13, thereby driving the rotating rod 14 to rotate. The pushing frame 15 at the bottom end of the rotating rod 14 continuously stirs the sieved raw materials into the material openings 25, and thus falls into the recovery tank 17 for collection.

[0027] Embodiment 2: The bottom end of the sieve plate 8 is inclined. A slot 22 is opened at the inner edge of the inner wall of the sieve plate 8. A sieve mesh 21 is inserted into the slot 22. A locking bolt 7 is fixedly connected between the sieve mesh 21 and the sieve plate 8. A material falling groove 20 is arranged at the bottom right end inside the sieve plate 8. A support frame 18 is arranged below the material falling groove 20. A collection box 19 is placed above the support frame 18. The width of the collection box 19 is greater than that of the sieve plate 8;

[0028] Specifically, as Figure 1 and Figure 2As shown, the device is provided with a detachable screen 21 at the sieve plate 8. During installation, the screen 21 is inserted into the slot 22 from the right side of the sieve plate 8, and the position of the screen 21 is locked using the locking bolt 7. After a period of operation, the locking bolt 7 can be loosened, and the screen 21 can be removed for cleaning to prevent blockage. Different-aperture screens 21 can also be replaced.

[0029] Embodiment 3: A retractable recovery tank 17 is provided inside the right side of the base 1, and the recovery tank 17 is located directly below the blanking tray 16.

[0030] Specifically, as Figure 1 , Figure 4 and Figure 5 shown, the raw materials falling at the sieve plate 8 enter the collection box 19. The full collection box 19 can be removed for subsequent processing, while the sieved small particles and debris enter the recovery tank 17 and can be pulled outwards. Since there is the blanking tray 16 above the recovery tank 17 to block it, it can prevent them from spreading to the outside.

[0031] Working principle: The oil-soluble pigment raw materials are put onto the inclined sieve plate 8. The variable-speed motor 24 is started, and the rotating shaft 23 drives the turntable 11 to rotate, thereby driving the turntable 11 to perform a circular motion with the rotating shaft 23 as the center point, thus pushing the movable frame 10 and the driving shaft 9 to perform a reciprocating linear motion in the horizontal direction. The high-frequency reciprocating swing forms a sieving motion, thereby realizing separation. The sieved raw materials roll from left to right at the sieve plate 8 and are collected in the collection box 19, while the small particles fall through the sieve holes of the screen 21 onto the slope plate 2 and roll to the blanking tray 16. The first gear 12 fixed at the front end of the rotating shaft 23 transmits torque to the second gear 13, thereby driving the rotating rod 14 to rotate. The pushing frame 15 at the bottom end of the rotating rod 14 continuously stirs the sieved raw materials into the material port 25, and thus they fall into the recovery tank 17 for collection.
