Description

Technical Field

[0002] Modified plastic processing equipment refers to a series of equipment used in the plastic modification processing system. After the screw extruder performs plastic modification processing, the plastic strip material needs to be cooled to achieve rapid molding processing of the plastic strip material.

[0003] Upon investigation, the invention patent discloses a modified plastic production and processing equipment and its processing technology (publication number: CN117799141A), including: an extrusion device, a cooling mechanism is installed at the end of the extrusion device, and the internal rotation of the cooling mechanism is connected to a guide mechanism, and the guide mechanism includes a guide wheel and an airbag ring; several of the guide wheels are connected through an adjustment mechanism, and the adjustment mechanism includes a rotating disk and a pressure relief groove; the cooling mechanism is also equipped with multiple groups of shaping mechanisms for re-correcting the shape of the granular raw material, and the shaping mechanism includes a shaping wheel; the shaping wheel is inwardly concave at the point where it contacts the granular raw material, and the radius is the same as the radius of the granular raw material. The present application has the advantages of standardizing and guiding the moving direction of the granular raw material, avoiding adhesion, reducing roller pressure, reducing and repairing the granular raw material, and accelerating the flow of cooling water, improving heat dissipation efficiency, etc.

[0004] Although the above patent realizes cooling of plastic particles by setting up a water-cooling structure, the movement direction of the plastic particles is roughly consistent with the direction of water flow, which causes the cooling water after the reaction to move along with the movement of the plastic particles, so that the surface of the plastic particles is in continuous contact with the cooled high-temperature water source, so that the plastic particles cannot perform continuous heat dissipation treatment after entering the cooling water, and only perform efficient heat dissipation treatment at the initial stage of entering the cooling water, resulting in a gradual decrease in the subsequent heat dissipation efficiency of the plastic particles, thereby reducing the overall heat dissipation and cooling effect of the plastic particles.
