Description

Technical Field

[0001] The utility model relates to the field of resin particle extrusion molding, in particular to an extrusion molding cooling device for resin particle production. Background Art

[0002] Resin pellet extrusion molding cooling refers to the process of cooling the thermoplastic resin from the extruder during the plastic extrusion process and quickly cooling it to form. During the resin pellet extrusion molding process, a cooling device, such as a cooling water tank or an air cooling system, is usually used to quickly reduce the temperature of the resin. This ensures that the resin solidifies quickly after extrusion molding to maintain the desired shape and size.

[0003] In the specific cooling of resin pellet extrusion molding, the resin needs to be mixed with other additives before being injected into the hopper. However, during the feeding process, the additives and resin may not be mixed evenly, which will affect the resin granulation. After the resin granulation process is completed, during the transportation process, the resin pellets may be retained for a long time, and the temperature drops and hardens, which affects the quality of the resin pellet products, as well as the appearance and performance, and is inconvenient for operators to use.
