Description

Technical Field

[0001] The utility model relates to the technical field of plastic masterbatch production, in particular to a cooling device for plastic masterbatch extrusion molding. Background Art

[0002] Masterbatch, a premix of pigment, carrier, dispersant, and additives, is a polymer composite coloring material widely used in industries such as plastics, textiles, coatings, and inks. Masterbatch also offers advantages such as good dispersibility, ease of use, energy conservation, and environmental protection. Driven by diverse sectors such as plastics products, packaging, automotive, and e-commerce, the market holds promising prospects for future growth.

[0003] Currently, masterbatches are generally extruded using an extruder. The extruded masterbatch is in the form of strips and is placed in a cold water pool for cooling. However, the cooling rate is slow when using only cold water, which reduces production efficiency. Secondly, after the hot masterbatch strips are in continuous contact with cold water, the cold water will gradually heat up. In particular, the cold water near the extruder discharge end will heat up much faster than the cold water at other locations, resulting in slower cooling efficiency. Utility Model Content
