AI Technical Summary
During the plastic extrusion process, the extruder die head is prone to blockage due to rapid cooling and solidification of the plastic, which affects the normal cutting of the pelletizer.
The vertical underwater pelletizer utilizes a design incorporating insulation and cutting components. After the plastic is extruded from the die head, it enters the insulation chamber, where high-temperature water is continuously supplied through the water inlet pipe to maintain the plastic's temperature. The cutting component then performs the cutting.
It effectively prevents die head clogging, ensures smooth cutting process, and improves cutting efficiency and pellet quality.
