Description

Technical Field

[0001] The present application relates to the technical field of polymer materials, and in particular to a masterbatch extrusion and pelletizing integrated device. Background Art

[0002] Masterbatch is a plastic colorant made of a high proportion of pigments or additives and thermoplastic resins that are well dispersed. Masterbatch is generally composed of three basic elements: pigments or dyes, resin carriers and additives. The selected resin has good wetting and dispersing effects on the colorant and has good compatibility with the colored material.

[0003] Traditional masterbatch processing requires that various materials be mixed evenly first, and then extruded. The extruded product needs to be pelletized. Although there are some water ring pelletizers on the market that can directly pelletize at the head of the extruder, their structure is complex, and the installation and maintenance costs are high, so they are less used.

[0004] At present, most manufacturers first process the extruded thermoplastic resin into strips, and then send the finished strips into a cutting machine for cutting. However, the extruded finished strips need to be cooled and air-dried before cutting. The existing extrusion pelletizing equipment will be equipped with a cooling water tank, and the finished strips will be cooled through the cooling water tank, and then enter the pelletizing mechanism after passing through the air-drying mechanism. The cooling water tank and the air-drying mechanism are long and occupy a large area.
