Detailed description of the invention
FIG. 1 is a schematic structural view of the utility model；
Fig. 2 is the utility model Section A-A enlarged structure schematic diagram.
In figure: double screw extruder 1, discharge nozzle 11, pelletizing cutter head 2, disk 21, thread barrel 22, bull stick 23, cutter
231, annular rack 24, second gear 25, shaft 26, position-limiting drum 27, belt 28, first pulley 29.
Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
Every other embodiment obtained, fall within the protection scope of the utility model.
The utility model provides a kind of technical solution referring to FIG. 1-2:
A kind of pelletizing cutterhead group device of double screw extruder, including double screw extruder 1, it is connected to double screw extruder
The discharge nozzle 11 of 1 discharge port and the pelletizing cutter head 2 being mounted on double screw extruder 1, pelletizing cutter head 2 is by justifying
Disk 21, thread barrel 22, bull stick 23, cutter 231, annular rack 24, second gear 25, shaft 26, position-limiting drum 27, belt 28 and
One belt wheel 29 composition；
Disk 21 is rotatably connected to thread barrel 22 close to a middle side part of discharge nozzle 11, and 22 screw thread of thread barrel is socketed in discharging
On pipe 11, disk 21 is fixedly connected with multiple inserted links close to the side of discharge nozzle 11, and the other end of inserted link is plugged on twin-screw and squeezes
Out on 1 side wall of machine in socket, the middle part of disk 21 offer with the matched through-hole of discharge nozzle 11, disk 21 is far from thread barrel 22
Side rotation connection is there are two bull stick 23, and two bull sticks 23 are located in same level, one end of the bull stick 23 close to disk 21
Wall is connected with cutter 231, and the length of cutter 231 is greater than the distance between through-hole distalmost end and bull stick 23, and the length of cutter 231
The shortest distance between less than two bull sticks 23 prevents from too short not cutting extruded stock, too long damage bull stick 23, two cutters
231 are centrosymmetric structure about the centers of two 23 lines of bull stick, and symmetrical in 180 °, guarantee that cutting every time is intermediate and stop
Time is identical, and fixing sleeve is connected to first gear on bull stick 23, and two first gears are sequentially connected with second by annular rack 24
