The present invention discloses a plastic
masterbatch granulation device, which relates to the technical field of plastic
masterbatch granulation, and includes a support seat and a rotary
pelletizing mechanism. The support seat is composed of a
processing chamber 1 for
cutting and cleaning arranged at the top, a horizontal plate fixed to the left inner wall of the
processing chamber 1, a collection bucket fixed in the middle, and a
processing chamber 2 for shaping arranged at the bottom. The driving mechanism is symmetrically provided with a rotary
pelletizing mechanism, and the rotary
pelletizing mechanism includes a disassembly
assembly component 1 for rapid disassembly and
assembly, and an auxiliary component for fixed-point
cold air cooling during
cutting and fixed-point hot
air heating during cleaning. The present invention is adapted to the driving mechanism and the rotary pelletizing mechanism, and two groups of blades alternately work to
cut the plastic strips extruded by the
extrusion device, thereby improving the
cutting efficiency of the device. After the driving
limiter releases the limit on the disassembly
assembly component, the disassembly assembly component and the blade are separated from the rotary seat as a whole, thereby realizing rapid disassembly and saving maintenance time.
