30 degree of angles, the exhaust pipe port are provided with filtration apparatus.
Preferably, the length of the agitating vane is more than lower hopper exit radius, under the length of the agitating vane is less than
Hopper inlet radius.The length range of agitating vane is set, ensures to be sufficiently stirred.
Preferably, the agitating shaft has been disposed radially no less than two groups agitating vanes.Multigroup agitating vane stirs at the same time,
Guarantee stirs evenly, and prevents part plastic grain from bonding.
Preferably, described cover board one end is hinged with upper shell, and the other end is pressed on upper shell.Cover board is easy to open, it is internal
Maintenance or cleaning dust.
Preferably, the filtration apparatus is pneumatic filter.
Preferably, the second motor control intermittent rotation of torsion shaft, rotates 180 degree every time.Torsion shaft drives upset
Plate rotates 180 degree every time, and intermittent rotation, ensures that rotating enlightenment state feed opening every time is in closed state, uniform blanking, subtracts
Dissipated in few equipment outside heat.
Preferably, the upper shell be circular cone build and cone angle downward, the lower housing shell is cylinder type.
Compared with prior art, the beneficial effects of the invention are as follows：
A kind of blanking device of Modified plastic extruder of the present invention, lower hopper is closed, avoid dust from shedding by lid；
The present invention drives plastic grain stirring, avoids plastic grain accumulation extruding by setting agitating shaft and agitating vane；
The present invention, with the uniform pan feeding of the second motor control interval, avoids feed opening normally opened, reduction is set by setting returning face plate
The diffusion of standby internal energy, avoids plastic grain heating from bonding, and reduces cost, improves efficiency.
The present invention in lower housing shell by setting exhaust pipe, and upward and with lower housing shell in 30 degree, exhaust tube end is set exhaust pipe
Filtration apparatus is put, thermal current in equipment is preferentially discharged from exhaust pipe, avoids thermal current from bonding plastic grain heating；
