The annular channel connects heat conductive circulation equipment, and pelletizing portion includes the pelletizing knife rest for being installed on temperature control portion front end, and for driving
The pelletizing motor of dynamic pelletizing knife rest inner blade rotation.
The region of die head has been carried out accurate division by the utility model, forms cooling end under the influence of water ring cover cooling water
It realizes and carries out abundant, uniform preheating before extrusion molding, temperature control portion are by pelletizing in molding extruded stock, then cut in pelletizing portion
It is cut into particle, exports molding materials.
Water ring cover described in the utility model is the cover that water torus is set in two semi-circulars, and split is installed on die head
On.Due to water ring cover and annular channel, the former realizes cooling, and the latter realizes heating, and effect both in order to prevent influences each other,
Heat insulation loop is equipped between the annular channel and water ring cover.The heat insulation loop is made of heat-barrier material, preferably uses ceramic material.
As advanced optimizing for the utility model, the position that the extruding cavity corresponds to temperature control portion forms bulb.It expands
Automatic deformation caused by internal stress when the design in portion allows for elastic material molding, and can occur gently under the influence of preheating
Microdilatancy, in order to guarantee that smoothly, the segment space of extruding cavity is suitably expanded for discharging.It further contracts in the extrusion direction of bulb
It is small, in favor of pelletizing.
Further, the heat conductive circulation equipment is heat conduction oil circulating pump.
Further, which further includes thermoelectric control cabinet, is equipped with and thermoelectric control cabinet communication link in the annular channel
The temperature sensor connect.The device can detect the Current Temperatures of heat-conducting medium in annular channel, control the material temperature of pelletizing end
Degree, and then prevent nozzle caused by cooling down because of transition from condensing.
The utility model has the advantages that the utility model is based on water ring cover inhomogeneous cooling bring discharge tip condensation problem, in discharge port
One end increases preheating circulatory flow, while advanced optimizing to the discharging chamber of head, improves discharging and pelletizing
Efficiency.
