The deep equidistant main thread such as have, compounding effect is bad.
Summary of the invention
The object of the present invention is to provide a kind of compounding effect more preferably screw rod discharging devices.
Above-mentioned technical purpose of the invention has the technical scheme that
A kind of screw rod discharging device, including sleeve, rotational installation in the screw rod in sleeve, the side of the discharge end of the screw rod
Several circle external tooth groups it have been axially fixed on wall, every circle external tooth group is by multiple external tooths for being arranged along screw rod circumferential direction uniform intervals
It forms, several circle internal tooth groups has been axially fixed on the sleeve lining, every circle internal tooth group is by between sleeve is circumferential uniformly
It being formed every multiple internal tooths of setting, the external tooth group and internal tooth group are arranged along setting, the internal tooth and screw rod interval is axially offset,
The external tooth and sleeve interval are arranged.
Further, the screw rod is made of the body of rod and the screw thread being fixed on outside the body of rod, and the body of rod is from feed end to out
Material end diameter is gradually increased setting.
Further, the discharge end of the screw rod is in isometrical cylindric, and the external tooth is Z along axial length, along axis

Further, described sleeve one end is equipped with stirring set, and the internal tooth is each attached in stirring set.
Further, the stirring set is made of multiple points of sets, fixes a circle internal tooth in each point of set.
Powder and polylactic acid slice (raw particles) enter from the feed inlet of sleeve, as the rotation of screw rod is pushed ahead.
There is array heating device (heating coil) in the outer circle of sleeve, when slice is pushed ahead in sleeve, gradually melts
As polylactic acid melt.Melt is in travelling forward, since screw spiral groove depth gradually becomes shallower as, so that melt is gradually pressed
Contracting, fusion pressure improve.After melt squeezes out helicla flute along the rotation of screw rod, by the gap between sleeve internal tooth and screw rod, external tooth
Gap between sleeve, gap, external tooth between sleeve internal tooth and screw rod and the gap between sleeve, are repeated several times.Due to
Sleeve internal tooth is static, and the external tooth on screw rod is rotated with screw rod.When melt flows through above-mentioned gap, melt is repeatedly
It is squeezed by external tooth, internal tooth dislocation, has reached good compounding effect.
