[0022] First, the plastic strip is extruded by an extruder and then enters the interior of the blade cooling box 11. At this time, cold water is injected into the cooling box 11 to quickly cool the plastic. Then the plastic passes through the clamping roller 10. Under the action of the clamping roller 10, the plastic is always in cold water, so that it is fully cooled, thereby avoiding the plastic from softening, sticking, or even melting, which will affect the cutting effect and make the cut particles uneven and the quality unstable. Then the cooled plastic enters the cutting table 7 through the guide assembly and then accurately reaches the bottom of the cutting assembly. In this way, the guide assembly can avoid the problem of deviation of the plastic during movement, thereby increasing the production efficiency of the device. Finally, the cutting assembly is started to pelletize the plastic strip. The pelletized plastic falls into the collection device through the inclined surface of the cutting table 7.

[0023] like Figure 1-Figure 4As shown, the guide assembly includes a laminating roller 18, which is rotatably connected to the inside of the fixed frame 6. A first motor 8 is fixedly installed on one side of the fixed frame 6. One end of the output shaft of the first motor 8 is fixedly connected to one end of the rotating shaft of the laminating roller 18. The guide assembly also includes an active roller 19, which is rotatably connected to the inside of the fixed frame 6. Grooves are equidistantly provided on the outside of the active roller 19.

[0024] When guiding the plastic, the strip plastic passes through the guide roller 9, which can be initially positioned and guided to prevent it from deflecting. Then the plastic enters between the laminating roller 18 and the active roller 19, and then the output shaft of the first motor 8 is started to rotate to drive the laminating roller 18 to rotate, thereby driving the strip plastic to move from the inside of the groove of the active roller 19 to the top of the cutting table 7, which can increase the stability of the plastic movement.

[0026] When cutting, the output shaft of the second motor 12 is started to rotate, driving the turntable 20 to rotate and driving the protrusion 16 to slide inside the displacement frame 15, thereby driving the slide rod 17 to slide inside the bracket 2 and driving the displacement plate 5 to reciprocate, and then driving the cutting knife 14 to quickly reciprocate and cut the plastic, thereby increasing the pelletizing efficiency of the device.

[0027] The utility model provides a plastic pelletizer with a cooling mechanism, and the specific working principle is as follows: first, a strip of plastic is extruded by an extruder, and then enters the interior of a knife cooling box 11, at which time cold water is injected into the interior of the cooling box 11, so that the plastic is quickly cooled, and then the plastic passes through a pressing roller 10, under the action of the pressing roller 10, the plastic is always in the cold water, so that it is fully cooled, and then, when the plastic is guided, the strip of plastic passes through a guide roller 9, so that the plastic can be initially positioned and guided to avoid its deviation, and then the plastic enters the laminating roller 18 and The active roller 19 is then started, and the output shaft of the first motor 8 is started to rotate to drive the laminating roller 18 to rotate, thereby driving the strip plastic to move from the inside of the groove of the active roller 19 to the top of the cutting table 7, which can increase the stability of the plastic movement. Finally, when cutting, the output shaft of the second motor 12 is started to rotate to drive the turntable 20 to rotate and drive the protrusion 16 to slide inside the displacement frame 15, thereby driving the slide bar 17 to slide inside the bracket 2 and drive the displacement plate 5 to reciprocate, and then drive the cutting knife 14 to quickly reciprocate and cut the plastic, thereby increasing the pelletizing efficiency of the device.
