In the production process of masterbatch, the pelletizer is one of the key equipment, which is used to cut the masterbatch into particles of a certain size and shape.

[0003] Chinese patent announcement No. CN213353087U proposes a plastic pelletizer. The utility model proposes the problem that "during the use of the pelletizer, only pelletizers of one size can be processed, and there is a defect of low applicability", and proposes the following technical solution: "Through the setting of the adjustment component, the position of the guide conveyor belt on the machine body can be adjusted, so as to achieve the purpose of adjusting the distance between the cutting roller and the guide conveyor belt, so that the pelletizer can cut plastic strips of different sizes, which plays a role in improving the applicability of the pelletizer; through the setting of the conveying channel and the discharge port, the cut plastic pellets can be discharged in time", however, dust and particulate matter will be generated during the pelletizing process.

[0038] It should be noted that thirteen partitions are fixedly connected between the inner top wall and the inner bottom wall of the feed bin 2, and the thirteen partitions are equidistantly distributed from front to back, separating several plastic strips to prevent several plastic strips from sticking together. One end of the front side of the transmission rod 6 is rotatably connected to the front side of the box body 1, one end of the front side of the first driven rod 10 passes through the front side of the box body 1 and extends to the interior of the box body 1 and is rotatably connected to the inner rear side wall of the box body 1, and a feeding barrel 16 is fixedly connected to the outer side of the end of the first driven rod 10 located inside the box body 1, and the feeding barrel 16 is used to convey the plastic strips so that the plastic strips can be pelletized by the pelletizing structure, and one end of the front side of the second driven rod 13 passes through the front side of the box body 1, the front side of the connecting barrel 14 and the back side of the connecting barrel 14 in sequence and is rotatably connected to the inner rear side wall of the box body 1, so that the connecting barrel 14 and the pelletizing blade 15 fixed on the outer surface of the connecting barrel 14 can pelletize the plastic strips located inside the box body 1.

A spring is provided on the outer side of the elastic telescopic rod 19, and a power amplifier is provided inside the ultrasonic generator 24 to increase the power of the ultrasonic wave.

[0043] The working principle of the above embodiment is:

[0044] The starting motor 5 drives the transmission rod 6 to rotate, and the transmission rod 6 then drives the transmission wheel 7 to rotate. The transmission wheel 7 drives the driven wheel 9 to rotate with the cooperation of the transmission belt 8. The first driven wheel 9 then drives the first driven rod 10 to rotate, and the first driven rod 10 then drives the feeding barrel 16 to rotate. At this time, the plastic strip is pushed into the silo 2, and one end of the plastic strip enters the interior of the box body 1. Then the electric push rod 17 is started to move the positioning barrel 21 downward, and then the plastic strip is positioned by cooperating with the feeding barrel 16. Due to the elastic properties of the elastic telescopic rod 19 and the spring, the positioning barrel 21 is prevented from crushing the plastic strip.

[0045] During the rotation of the first driven rod 10, the driving gear 11 is driven to rotate, and the driving gear 11 then drives the driven gear 12 meshing therewith to rotate, and the driven gear 12 then drives the second driven rod 13 to rotate, and the second driven rod 13 then drives the connecting cylinder 14 to rotate, and the connecting cylinder 14 then drives the pelletizing blade 15 to rotate, and the pelletizing blade 15 pelletizes with the cooperation of the fixed knife 4, and the plastic particles fall onto the screen 27 through the inclined surface of the support platform 3.

[0046] The ultrasonic generator 24 is started and generates ultrasonic waves. At the same time, the ultrasonic waves amplify the signals generated by the ultrasonic generator through the built-in power amplifier of the ultrasonic generator 24 to generate sound waves of sufficient intensity. By adjusting the parameters such as the frequency, amplitude and waveform of the ultrasonic waves, the screening effect on the plastic particles can be achieved. Finally, the ultrasonic waves are transmitted to the screen 27 through the ultrasonic connector 25.
