, the stator internal standard face and outer surface are eccentric, just because of the presence of eccentric throw, and the volume of single cavity volume is only can
With change；It is described charging baffle plate and discharge baffle external diameter it is big as the stator outer diameter, its screw also with stator
Screw has same size and location, when single cavity volume volume is changed from small to big, can produce a negative pressure region, previous section
Material will enter current session from charging baffle plate, when single cavity volume volume from large to small when, material is again under pressure from going out
Material baffle plate goes to next section, and the gap of the baffle plate internal diameter and rotor outer surface constitutes charging aperture or discharging opening, described
Charging aperture and discharging opening are to appear in the stator both sides in pairs and aperture position is different, so as to ensure each plasticization unit
It can feed and discharge simultaneously.
Preferably, described blade plasticizing supply unit is three or more than three.
The blade angle of adjacent plasticizing supply unit differs 45 °, and the eccentric direction of adjacent plasticizing supply unit is on the contrary, the
The charging aperture design of one blade unit stator radial direction, and it is opening up be connected with hopper, last blade unit
Discharging opening is in rotor axial, naturally it is also possible in stator radially, and the charging aperture and discharging opening of other units are in rotor axial and preceding
The discharging opening of one unit is exactly the charging aperture of latter unit.In a unit, its charging aperture and discharging opening be not same
On bar line, one above, one below, and certain charging aperture and discharging opening can also use the combination of other forms, so
Matching relationship can ensure same unit and meanwhile feed and discharge, do not interfere with each other.
Beneficial aspects of the present utility model are：The thermomechanical course that completion plasticizing transport process is undergone is greatly shortened, and is moulded
Change transports energy consumption reduction, and corresponding plasticizing conveying equipment, which is submitted, to be reduced, physical characteristic of the plasticizing transport capability independent of material,
Plasticizing transports stability raising, adapts to material new improve.
