Plastic granulating device

Abstract

The invention discloses a plastic granulating device, and relates to the field of plastic processing. The plastic granulating device comprises a frame; a cantilever is fixed on the frame; one end of the cantilever is fixed on the frame; a cutting motor is arranged at the other end of the cantilever, and includes a rotor, a stator and a cutting mechanism; the stator is fixed on the cantilever; the rotor is rotationally connected with the stator; a center through hole penetrates through the centers of the rotor, the stator and the cantilever; multiple chutes and cutters uniformly distributed in the center of the rotor; slide blocks capable of sliding in the chutes are arranged in the chutes; the cutters can slide in the radial direction along the rotor; tips of the cutters extend into the center through hole; the tail ends of the cutters are matched with the wedge surfaces of the slide blocks; and the cutters are coated with return springs. When the plastic granulating device cuts plastic pipes, the plastic pipes are uniformly stressed; and the plastic pipes are still located in the center through hole after cutting, so that the damage of the plastic pipes can be prevented.

Description

technical field [0001] The invention relates to the field of plastic processing, in particular to a device for cutting plastic pellets. Background technique [0002] Plastic is a polymer compound (macromolecules) that is polymerized by addition or polycondensation of monomers, commonly known as plastics or resins. It can freely change its composition and shape. It is composed of synthetic resins and fillers, Composed of additives such as plasticizers, stabilizers, lubricants, and pigments, it can be widely used in various fields such as chemical industry, aerospace, military, family, and hospitals, and has good promotion value and social benefits. [0003] Pelletizing of plastic pipes includes fixed-length cutting and pelletizing cutting. Fixed-length cutting is an important process. The processing quality of this process directly affects the pelletizing effect; the existing plastic pipe cutting devices mostly use cutting plastic pipes from the outside of the plastic pipe. ...

AI Technical Summary

Problems solved by technology

Existing plastic pipe cutting devices usually only have one cutter, so when the cutter rotates, periodically changing pressure will be formed on the outer surface of the plastic pipe, resulting in uneven force on the plastic pipe and easy damage to the plastic pipe; After the tube is cut, it will fall directly, and it is often damaged by the high-speed rotating cutter
