Description

Technical Field

[0001] The utility model relates to the technical field of granulators, in particular to a granulator used for producing polyester fiber flame retardant masterbatch. Background Art

[0002] Existing granulators for the production of polyester fiber flame retardant masterbatch all melt and mix the materials and then extrude them through an extrusion device, and use a cutter at the extrusion end to cut the melt into the required masterbatch. However, the masterbatch is mostly cooled naturally during extrusion, and is still in a softened state during the cutting process of the cutter, which can easily cause the final masterbatch to deform. At the same time, cold water is sprayed to replenish the molten material, which will cause part of the melt to solidify while replenishing water, resulting in the failure to form a uniform masterbatch in the end. For example, a plastic masterbatch granulator disclosed in a Chinese patent, whose application number is CN202320653886.4, although a water spraying device is provided at the extrusion end to cool the melt by spraying water during cutting and granulation, so that the masterbatch will not be deformed when the cutter cuts, but cooling by a method in which water directly contacts the melt will destroy the shape of the melt, so that the generated masterbatch cannot form the desired shape. At the same time, the method of directly cooling with water will pollute the environment, and there is no effective use of cooling water, so the use is limited. Utility Model Content
