Technical Field

[0002] Plastic masterbatch is a concentrate made by attaching an abnormal amount of plastic additives to the resin. When manufacturing plastic products, there is no need to add this kind of plastic additives. When producing plastic masterbatch, the temperature of the plastic masterbatch raw material is relatively high after it is extruded into strips by an extruder. It is cooled by a cooling device and then cut into pellets by a pelletizer. The cooling device consists of a water collecting tank, a water outlet pipe, a water pump, a water injection pipe and multiple groups of rollers. Water is injected through the water injection pipe. After the plastic masterbatch raw material is extruded into strips by an extruder, workers put the strip-shaped plastic masterbatch into the water collecting tank through a rod, so that the residual heat on the surface of the plastic masterbatch is absorbed by the water, so that the water is heated, and then the plastic masterbatch is pulled, so that the strip plastic passes through multiple groups of rollers and is finally put into the pelletizer to be cut into pellets. The hot water in the water collecting tank is discharged through the cooperation of the water pump and the water outlet pipe.
