[0034] Example 1

[0035] Please see Figures 1-4 The technical solution provided in this embodiment is as follows:

[0036] A pelletizing device for masterbatch consists of a pelletizing box 1, a discharge pipe 4, a circular cutter 9, a drive mechanism, a conveying mechanism, and a screening mechanism. The circular cutter 9 is rotatably connected between the side walls of the pelletizing box 1, and both ends of the circular cutter 9 rotatably penetrate the pelletizing box 1 and extend to the outside of the pelletizing box 1.

Each gear 5 is fixedly connected to one end of each conveying roller 6. The two gears 5 mesh with each other.

[0041] In a specific embodiment of this utility model, the rotation of the conveying roller 6 drives the gear 5 to rotate. Since the two gears 5 mesh with each other, the two gears 5 rotate in opposite directions at the same time. The simultaneous rotation of the two gears 5 in opposite directions can realize the simultaneous rotation of the two conveying rollers 6 in opposite directions, and the simultaneous rotation of the two conveying rollers 6 in opposite directions can convey plastic strips.

[0042] Specifically, the transmission component is located on the conveying component and the circular cutter 9. The transmission component includes a pulley B16 and a transmission belt B17. There are two pulleys B16, one of which is fixedly connected to one end of one of the conveying rollers 6, and the other pulley B16 is fixedly connected to one end of the circular cutter 9.

[0043] In a specific embodiment of this utility model, the circular cutter 9 rotates to drive the pulley B16 to rotate. Since the transmission belt B17 is connected to the two pulleys B16, the two pulleys B16 rotate simultaneously, and the rotation of the pulleys B16 drives the conveyor roller 6 to rotate.

[0044] Specifically, the screening component is located on the pelletizing box 1. The screening component includes a coarse-pore screen plate 10, a fine-pore screen plate 11, a partition plate 13, shock absorbers A14 and B15.

The rotation of the eccentric wheel 12 also drives the pulley A3 to rotate. Since the transmission belt A2 is connected to the two pulleys A3, the two pulleys A3 rotate simultaneously. The simultaneous rotation of the two pulleys A3 enables the two eccentric wheels 12 to rotate simultaneously, which in turn pushes the coarse-hole screen plate 10 and the fine-hole screen plate 11 to move respectively.

[0048] The working principle or process of the masterbatch pelletizing device provided by this utility model is as follows: The rotating conveyor roller 6 drives the gear 5 to rotate.

This simultaneous counter-rotation of the two gears 5 enables the two conveyor rollers 6 to rotate simultaneously in opposite directions, thus conveying plastic strips. The rotating circular cutter 9 drives the pulley B16 to rotate. Since the transmission belt B17 is connected to the two pulleys B16, the two pulleys B16 rotate simultaneously, driving the conveyor rollers 6 to rotate. The partition plate 13 is used to connect the shock absorber A14. The coarse-mesh sieve plate 10 and the fine-mesh sieve plate 11 are used to screen the masterbatch. The shock absorber... A14 is used to connect the fine-pore screen plate 11, and B15 is used to connect the coarse-pore screen plate 10. The rotation of the conveyor roller 6 drives the pulley C19 to rotate. Since the transmission belt C18 is connected to the two pulleys C19, the two pulleys C19 rotate simultaneously. The rotation of the pulleys C19 drives the eccentric wheel 12 to rotate. The rotation of the eccentric wheel 12 can push the fine-pore screen plate 11 to move. The rotation of the eccentric wheel 12 drives the pulley A3 to rotate. Since the transmission belt A2 is connected to the two pulleys A3, the two pulleys A3 rotate simultaneously. The simultaneous rotation of the two pulleys A3 can realize the simultaneous rotation of the two eccentric wheels 12. The rotation of the two eccentric wheels 12 respectively pushes the coarse-pore screen plate 10 and the fine-pore screen plate 11 to move.
