Technical Field

The invention relates to the technical field of plastic production equipment, in particular to a granulating bracing piece cooling device.

Background

The color master batch is a novel special coloring agent for high polymer materials, is also called a color seed, is a novel special coloring agent for high polymer materials, has good dispersibility and chemical stability, and keeps the cleanness of the environment in the using process, thereby being widely applied to the plastic industry.

The water temperature monitoring controller 6 is provided with a controller probe which is positioned in the middle of the front and back directions of the water tank body 1. Because the water temperature in the middle of the water tank is stable, the water temperature at the water inlet is low, the water temperature at the water outlet is high, and the water temperatures at the two ends are uneven, the controller probe is arranged in the middle of the water tank body 1 to realize temperature detection, and the accuracy of the value of a temperature measuring point is facilitated.
