Lower section is equipped with the cooling chamber with the same size shape of heating chamber, and outside is wrapped in condensate liquid pipeline, in condensate liquid pipeline
Passing to the big condensed fluid of the specific heat capacities such as water reduces cooling chamber's internal temperature, makes the fast quickly cooling of filamentary material squeezed out by piston
But cure, prevent adhesion between silk, granulating is cut convenient for the later stage.Since cooling chamber's lower inner surface is up big and down small circular cone
Face, Filamentous consumptive material is in circular conical surface region with the reduction of cross section, and filamentary material is gathered to center and gap reduces between silk.
A kind of 3D printing waste recycling device of the present invention drives main shaft to turn by the motor being fixed on pedestal
Filamentary material that is dynamic, making the blade on axis to be cooled and solidified at certain frequency cutting cooling chamber lower part outlet, forms granular
Consumptive material, and fall into extruder charge door.
Granular consumptive material is fallen into its feed inlet in a kind of extrusion system of 3D printing waste recycling device of the present invention,
By the way that 3D printing filiform consumptive material is made after screw rod melting extrusion.Electric coil winder at cross-head orderly winds extrusion
The Filamentous consumptive material that machine squeezes out, helps to maintain consumptive material filament diameter consistency.
A kind of 3D printing waste recycling device processing method of the present invention is：Using mounted on heating chamber outer ring
Resistance heating coil heating, which is placed in surface layout, discarded printed material on the sieve plate of uniform hole.Motor drive drives leading screw
Rotation makes piston squeeze molten state material downwards, and material becomes Filamentous molten state material, material by being pressed through sieve pore
Stream it is wrapped become cured filamentary material after the cooling chamber of condensate line, cut by rotary cutter motor-driven
It cuts and bulk material is made, and fallen into extruder hopper by gravity, by the way that 3D printing filiform consumption is made after screw rod melting extrusion
Material, the electric coil winder at cross-head orderly wind the Filamentous consumptive material of extruder extrusion.
The present apparatus can realize the recycling of 3D printing consumptive material and defect ware, reduce to a certain extent 3D printing at
This, makes 3D printing technique more low-carbon environment-friendly.
