The discharge cooling device has the beneficial effects that air generated by the fan can be effectively used for a melting material, so that the material can be fast cooled in the melting and forming processes, so as to avoid the buckling deformation of the material in the slowly radiating process due to different local temperatures, and the forming quality can be remarkably improved.
Description
Technical field
The utility model relates to 3D printer technology field, relates in particular to a kind of cooling device for discharging for 3D printer.
Background technology
3D printing technique, to design a model as source taking Computerized three-dimensional, discrete and the numerical control molding system by software hierarchy, utilize the mode such as laser beam, hot melt nozzle that the special materials such as metal dust, ceramic powders, plastics, cell tissue are successively piled up and cohered, final stack moulding, produces entity products.3D prints 3D solid is become to several two dimensional surfaces, by material processed successively stack are produced, greatly reduces the complexity of manufacture.This digitlization manufacturing mode directly just can generate the part of any shape from computer graphics data.
Fusion sediment moulding (FDM) technology is a mainstream technology in 3D printing technique, and fusion sediment moulding (FDM) technology is that cad model is divided into from level to level to cross section as thin as a wafer, generates the two-dimensional geometry information of controlling 3D printer nozzle motion track.3D printer heating head is heated to critical condition heat-fusible materials (ABS resin, nylon, wax etc.), present semifluid character, under computer control, along the definite two-dimensional geometry information movement track of CAD, shower nozzle squeezes out the material of half flow regime, solidifies the thin layer that forms contour shape.After one deck, fall new formation layer by vertical lift system, be cured.Pile up so layer by layer bonding, form the 3D solid of this model from bottom to top.
One of key issue of the 3D printer of application fusion sediment moulding (FDM) technology is formed precision problem, and formed precision transmission accuracy affects, is also subject to the impact of the cooling strain of material except being subject to a great extent.According to test, in melted material forming process, can produce distortion warpage because of cooling range, greatly reduce formed precision.But domestic current being seen 3D printer is often ignored the cooling control of material, so, for improving the formed precision of 3D printer, need a kind of cooling device for discharging efficiently.
Summary of the invention
The purpose of this utility model is in order to overcome the deficiencies in the prior art, and a kind of cooling device for discharging of 3D printer is provided.
Cooling device for discharging for 3D printer comprises auxiliary body, wind pushing mechanism, drainage mechanism, and supplementary structure comprises shell, grill-protected, screw, fixed block, and wind pushing mechanism comprises pulse width modulation fan, and drainage mechanism comprises arc-like rows tuyere; Shell is fixed by screws on fixed block; pulse width modulation fan is fixed by screws on shell; grill-protected is fixed by screws on shell; screw is fixed on the right side of fixed block from outside to inside successively through grill-protected, pulse width modulation fan, shell; the fixing discharge head of downside of fixed block, shell below is provided with arc-like rows tuyere.

Detailed description of the invention
As shown in Figure 1, 2, cooling device for discharging for 3D printer comprises auxiliary body, wind pushing mechanism, drainage mechanism, supplementary structure comprises shell 1, grill-protected 4, screw 3, fixed block 7, and wind pushing mechanism comprises pulse width modulation fan 2, and drainage mechanism comprises arc-like rows tuyere 5; Shell is fixed on fixed block 7 by screw 3; pulse width modulation fan 2 is fixed on shell 1 by screw 3; grill-protected 4 is fixed on shell 1 by screw 3; screw 3 is fixed on the right side of fixed block 7 from outside to inside successively through grill-protected 4, pulse width modulation fan 2, shell 1; the fixing discharge head 6 of downside of fixed block 7, shell 1 below is provided with arc-like rows tuyere 5.
The air outlet place of described arc-like rows tuyere 5 is provided with air-flow guiding curved surface.
The course of work of 3D printer cooling device for discharging is as follows: after 3D printer is started working, system is chosen corresponding control parameter according to printed material the pulse width modulation fan 2 in discharging heat abstractor is driven to control, reconcile its working speed, the wind that pulse width modulation fan 2 produces to after the inner chamber of shell 1 because pressure differential moves downward, air-flow is downward through the discharging opening of discharge head 6 through the guide effect rear-inclined of arc-like rows tuyere 5, take away a part of heat of melted material, make melted material cooling rapidly from discharging opening is extruded, realize refrigerating function, avoid material in slowly heat radiation process to cause buckling deformation because local temperature is different, ensure Forming Quality.
