A double screw extruder pelletizing cutter device

Abstract

The utility model discloses a double screw extruder granulating hob device in the technical field of chemical equipment, include: granulating hob subassembly, be located in the upper of the plate type conveyer belt of double screw extruder export end, is used for the rotating cutting of the plastic strip bundle after extrusion forming, forms granular material, push material mechanism, be located in the downstream side of granulating hob subassembly, is used for the granular material through intermittent airflow to act on granular material to make granular material on the plate type conveyer belt staggered distribution state, wherein, push material mechanism includes air pump, be located in the air outlet of air pump's air jet pipe, is used for the intermittent unit of the control air jet pipe intermittent air jet, and support frame, support frame fixedly be located on the frame of plate type conveyer belt, air pump, air jet pipe and intermittent unit all install on support frame. The device adopts the granulating hob subassembly of electric drive, can realize even granulation, guarantee product quality, and make the particle on the plate type conveyer belt staggered distribution state through push material mechanism, effectively avoid the granule between the group.
