Embodiment mono-
The present embodiment provides a kind of plastic cement smelting furnace of 3D printer, and this plastic cement smelting furnace as depicted in figs. 1 and 2, comprising: feed arrangement 101, body of heater 102, motor-driven valve 103, feeding engine 104 and nozzle 105;
Wherein, described body of heater 102 is followed successively by from inside to outside: cavity 1021, body layer 1022, thermal insulation layer 1023, zone of heating 1024 and insulated thermal insulating layer 1025; Above-mentioned cavity 1021 is specifically as follows the space of dress raw material.
Wherein insulated thermal insulating layer 1025 is that directly the exposed part dissipation of heat that can make in air is in air in order to prevent zone of heating, and in addition, zone of heating is exposed also easily scalds the user in air.The purpose of insulation is in order to prevent electric leakage.
Feed arrangement 101 is arranged on the top of body of heater 102, and feed arrangement 101 is communicated with cavity 1021;
Motor-driven valve 103 is arranged on the bottom of body of heater 102, and a side of motor-driven valve 103 is communicated with cavity 1021, and opposite side is communicated with feeding engine 104, and the bottom of feeding engine 104 is provided with nozzle 105.Whether the raw material that this electrically operated valve can be controlled cavity flow into feeding engine 104, be that electrically operated valve is opened, the raw material of cavity 1021 can flow into feeding engine 104 by motor-driven valve, and electrically operated valve is closed, and the raw material of cavity 1021 cannot flow into feeding engine 104 by motor-driven valve.
The operation principle of the plastic cement smelting furnace that the utility model provides is, when being duty, raw material enters cavity 1021 from feed arrangement 101, then zone of heating 1024 starts heating, thermal insulation layer 1023 conducts the heat of zone of heating 1024 to body layer 1022, body layer 1022, along with temperature raises, becomes liquid by the heating raw materials in cavity; Now as needed, print, motor-driven valve 103 is opened, liquid material just arrives feeding engine 104 through motor-driven valve 103, feeding engine 104 is sent liquid material by nozzle, so just can realize that 3D prints, because in the plastic cement smelting furnace that the utility model provides, liquid charging stock is more even, it can avoid the step effect, in addition, directly with liquid raw material, print and also can improve faster print speed.
