AI Technical Summary

Technical Problem

In the prior art, the rotary knife can only be cut into plastic once, and the efficiency is low.

Method used

A plastic pelletizing machine is designed, which adopts a combination of a screw, a discharge plate, a rotary shaft, a first cutter and a second cutter. Two sections of plastic can be cut at the same time by rotating the rotary shaft at one time, improving the cutting efficiency.

Benefits of technology

The rotating shaft can cut the plastic twice by turning twice, significantly improving the efficiency of plastic pelletizing.

Abstract

The utility model discloses a plastic granulator, including a machine body, a screw is arranged inside the machine body, a first motor is arranged at one end of the machine body, a power output end of the first motor is fixedly connected to the screw, a discharge plate is fixedly arranged at the other end of the machine body, a rotating shaft is arranged at the upper part of the side of the discharge plate away from the screw, a first cutter and a second cutter are fixedly sleeved on the outer surface of the rotating shaft in sequence, a second motor is arranged on the upper surface of the machine body, and the power output end of the second motor is fixedly connected to the rotating shaft. The utility model is provided with a screw, a discharge plate, a rotating shaft, a first cutter, and a second cutter. The screw rotates to plasticize and melt the material, and then extrudes it into strip or band-shaped plastic through the die hole of the discharge plate. The rotation of the rotating shaft drives the first cutter and the second cutter to rotate simultaneously to cut and truncate the strip or band-shaped plastic into particles, so that the rotating shaft can cut the plastic twice in one rotation, that is, cut two sections of plastic, which is more efficient.
