Description

Technical Field

[0001] The utility model relates to the technical field of barrel cleaning, in particular to a barrel cleaning device for a twin-screw extruder without damaging the inner wall. Background Art

[0002] Extruder is the most widely used plastic processing machinery. The principle of extruder is mainly to fully plasticize and mix the processing materials and then form them through a die. In terms of rotation direction, it can be divided into co-rotating extruder and counter-rotating extruder. According to the number of screws, it can be divided into screw-free, single-screw, twin-screw, three-screw and planetary extruders.
