The utility model discloses an extruder for
plastic film production, which comprises an extruder body, one side of the upper surface of the extruder body is communicated with a material injection
pipe, the upper end of the material injection
pipe is provided with a
material storage hopper, the lower end of the
material storage hopper is communicated with the material injection
pipe through a connecting short pipe, and an opening at the upper end of the
material storage hopper is fixedly connected with a cross beam. A vertical shaft is rotationally connected to the middle of the bottom face of the beam.
Powder is poured into the material storage hopper, the motor drives the vertical shaft to rotate, at the moment, the stirring rod rotates in the
powder, accumulation is avoided, meanwhile, the
quantitative structure is driven to quantitatively inject the
powder into the material injection pipe, meanwhile, the heating
assembly is controlled to dissipate heat, and the
powder passing through the material injection pipe is preheated; and finally, the powder falls into the extruder body and is extruded along with the movement of the screw rod, the powder entering the extruder is more uniform through quantitative discharging, meanwhile, the powder can be preheated, and the melting and
mixing effect and the
granulation quality are improved.
