Description

Technical Field

[0001] The utility model belongs to the technical field of cooling, and more specifically relates to a cooling device for plastic additive particles. Background Art

[0002] Plastic additives, also known as plastic additives, are compounds that must be added to polymers (synthetic resins) during the molding process to improve their processing properties or compensate for the inherent performance deficiencies of the resin. These additives play a vital role in plastic processing, including but not limited to plasticizers, heat stabilizers, antioxidants, light stabilizers, flame retardants, foaming agents, antistatic agents, mildew inhibitors, colorants and whitening agents (pigments), fillers, coupling agents, lubricants and release agents.

[0003] At present, in the production process of plastic additives, it is necessary to cool the plastic additive particles extruded by the extruder to avoid a series of problems such as hardening, discoloration, and modification. However, in the process of cooling the plastic additives, the existing cooling device generally transports the plastic additives through a pipe or conveyor tray with heat conductivity, and then cools the plastic additives in conjunction with the cooling system. The pipe or conveyor tray is generally provided with a certain inclination angle so that the plastic additives can undergo heat exchange and cooling in the process of sliding downward. Although cooling is achieved, the inclination angle of the pipe or conveyor tray of the existing cooling device is not easy to control the speed at which the plastic additives slide downward. When the inclination angle of the pipe or conveyor tray is too large, it is easy to cause the plastic additives to slide too fast and the target cooling effect cannot be achieved. When the inclination angle of the pipe or conveyor tray is too small, it is easy to cause the plastic additives to slide too slowly and stack and stop sliding, and the plastic additives cannot be cooled.
