[0005] (2) Technical Solutions

[0006] To achieve the above objectives, the present invention is realized through the following technical solutions: A plastic classification and pelletizing device specifically includes:

[0007] A base mechanism, which has a square main body, mounting circular plates installed on the front and back of the top of the square main body, a pelletizing mechanism arranged on the side where the mounting circular plates are close to each other, and a limiting panel fixed on the top of the mounting circular plates. The pelletizing mechanism includes:

[0008] An extrusion mechanism, which has a spherical main body, a feed hopper installed on the top of the outer surface of the spherical main body, pelletizing rods installed on the front and back of the spherical main body, a driving motor arranged on the side of the pelletizing rod away from the spherical main body, and air injection discs arranged on the front and back of the spherical main body. Through the design of the spherical main body of the extrusion mechanism itself, the surface smoothness of the overall device is improved, the concentration of heat during extrusion caused by the generation of sharp corners is avoided, the thermal fatigue of the components themselves is protected, and at the same time, the surrounding operators are protected to avoid scalding or collision of personnel.

[0009] Preferably, the top of the granulation mechanism penetrates through the limiting panel and extends to the top of the limiting panel, and the granulation mechanism is located directly above the base mechanism. The outer surface of the driving motor is mounted on the mounting circular plate, and the granulation rod is located on the outer surface of the extrusion mechanism. Through the setting of the air injection disc, the inside of the extrusion mechanism is connected to the outside, which facilitates the operator to adjust the air flow and air pressure of the internal components, and to control the internal temperature, so as to control the solidification degree of the extrusion raw materials and avoid the adhesion of the raw materials to the equipment after granulation.

[0010] Preferably, the extrusion mechanism includes:

[0011] A central column, which has a long strip-shaped rod, and a cross-shaped grinding plate mounted on the outer surface of the long strip-shaped rod, and an arc-shaped elastic plate fixed between the cross-shaped grinding plates;

[0012] An extrusion cylinder, which has a spherical cylinder body, and a shaping hole opened at the lower right position on the inner surface of the spherical cylinder body. Through the setting of the arc-shaped elastic plate, the angle of the cross-shaped grinding plate can be adjusted. While the cross-shaped grinding plate rotates itself to mix the extrusion raw materials to prevent condensation, multiple forces are applied for extrusion, improving the thoroughness of the shaping of the extrusion raw materials and avoiding waste of resources caused by raw material residues.

[0013] Preferably, both ends of the central column penetrate through the extrusion cylinder and extend to the outer surface of the extrusion cylinder, and the outer surface of the cross-shaped grinding plate is connected to the extrusion cylinder, and both ends of the central column are connected to the driving motor.

[0016] Preferably, the side of the bottom end of the end rod away from the feed hopper is connected to the extrusion mechanism, and the side of the telescopic insertion plate close to the air injection disc is connected to the extrusion mechanism. Through the magnetic force to drive the components, the self-position adjustment of the components is realized, avoiding damage to the components during movement.
