Background technology
Existing scroll feeder, comprise cylindrical shell and be arranged on the interior rotor of cylindrical shell, be wound with helicallobe on the rotor, the cylindrical shell two ends are connected with inlet point and discharging opening respectively, reducing motor is connected with an end of rotor by coupler, and drives the rotor rotation, and material enters in the cylindrical shell from inlet point, be delivered to discharge end by helicallobe and discharge from discharging opening, the rotor at discharging opening place is provided with brokenly the arch blade.This scroll feeder; it is less that helicallobe cross-sectional plane diametrically accounts for the ratio of whole mass transport cross-sectional plane; when the helicallobe at discharging opening place rotates to from top to bottom the position; the material ratio of carrying is many when position from bottom to top; in addition owing to viscosity between material and the helicallobe; material falls after being brought to certain altitude sometimes; so the position when material leaves helicallobe is uncertain; and material is in self gravitation effect current downflow or cave in; will form a dip plane at discharge end; all cause existing scroll feeder convey materials inhomogeneous, thereby influence bulking machine; comminutor; the stability of granulator operation influences the quality of finished product.
The utility model content
For solving the uneven problem of convey materials in the prior art, the utility model provides a kind of constant scroll feeder.
For solving above technical matters, the technical solution of the utility model is, a kind of constant scroll feeder is provided, comprise cylindrical shell and be arranged on the interior rotor of cylindrical shell, be wound with helicallobe on the rotor, the cylindrical shell two ends are connected with inlet point and discharging opening respectively, and the cross-sectional plane near discharge port end in the cylindrical shell is provided with cylindrical shell osed top baffle plate, and baffle plate is provided with the material extrusion.
Adopt above structure, the discharge end of cylindrical shell is sealed by baffle plate, and material can not form the dip plane at discharge end, can be full of the discharge end of cylindrical shell, is extruded equably from the material extrusion under the promotion of helicallobe.
Material extrusion on the baffle plate can be fan groove, is positioned at the bottom of baffle plate excircle.
Material extrusion on the baffle plate can be kidney slot, along being rectangular distribution on the circumference in the center of circle with the baffle plate center.
Material extrusion on the baffle plate can be through hole, and along being rectangular distribution on the circumference in the center of circle with the baffle plate center, through hole is provided with exit skirt near a side of helicallobe.
As improvement of the present utility model, discharging opening is square, and the outside of baffle plate is concordant with the wallboard inboard of discharging opening.Can guarantee to pass the material of baffle plate extrusion like this, can freedom fall without barrier, until discharging from discharging opening.
As another improvement of the present utility model, the pitch of discharge zone helicallobe is less than the pitch of feed zone helicallobe.Can strengthen the pushing force of discharge zone helicallobe like this, make the material can be smoothly by the material extrusion on the baffle plate.
