Description
Technical field
The utility model relates to a kind of 3D printing head, and specifically a kind of 3D printing head being applicable to tabletop machine, belongs to 3D printing device technical field.
Background technology
3D printing technique is a kind of advanced manufacturing technology of in recent years rising, and 3D printing head is the core component of printer, is also core technology.
On current market, modal 3D printing head is primarily of motor, fan, heat radiation rack, wire feed guide wheel, heating aluminium is fast, nozzle is formed by assembling, this printer arrangement is compact, installation and debugging are convenient, printing consumables can be melted by nozzle smoothly, but the shower nozzle of this structure, member processing cost is relatively high, the heat of heated aluminum block is easily passed to peripheral parts, and area of dissipation is little, thus it is uneven to cause complete machine heat to transmit, affect surrounding components and shower nozzle life-span, and the time that shower nozzle prints from being preheating to is longer, affect printing effect.
Summary of the invention
The purpose of this utility model is to provide a kind of 3D printing head being applicable to tabletop machine, and structure is simple, reasonable in design, can overcome existing shower nozzle heat and transmit uneven, that area of dissipation is little, shower nozzle preheating time is long, printing effect is low shortcoming.
To achieve these goals, the utility model provides a kind of 3D printing head being applicable to tabletop machine, comprise shower nozzle, shower nozzle inner sleeve runs through and is arranged in shower nozzle, also comprise PEEK pipe, wire feed trunnion, ceramic insulation cotton, ceramic heating flake, the upper end of shower nozzle is processed with external screw thread, and cotton is arranged on the external screw thread of shower nozzle successively for ceramic heating flake, ceramic insulation; The lower end of wire feed trunnion is connected with shower nozzle inner sleeve, and upper end is communicated with the gauge orifice in steady rest, and wire feed trunnion is processed with external screw thread; The lower end of PEEK pipe is connected with ceramic insulation cotton, and upper end is connected with steady rest; Described PEEK pipe is processed with internal thread, matches with the external screw thread of wire feed trunnion.
Further, the upper end of shower nozzle contacts with ceramic heat is unilateral.
Further, shower nozzle inner sleeve is the long-range feed pipe of PTFE Teflon pipe.
Beneficial effect: external screw thread is set by the upper end at shower nozzle, ceramic heating flake, ceramic insulation cotton are arranged on the external screw thread of shower nozzle successively, the lower end of wire feed trunnion is connected with shower nozzle inner sleeve, upper end is communicated with the gauge orifice in steady rest, external screw thread is processed with at wire feed trunnion, make its with processing female PEEK pipe with the use of, this printing head structure is simple, increase being heated and area of dissipation of shower nozzle, thus avoid the phenomenon of the printing precision reduction that complete machine causes because heat transmission is uneven, further increase printing effect.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1, PEEK pipe, 2, wire feed trunnion, 3, ceramic insulation is cotton, 4., ceramic heating flake, 5, shower nozzle, 6, shower nozzle inner sleeve, 7, steady rest.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Figure 1, a kind of 3D printing head being applicable to tabletop machine, comprise shower nozzle 5, shower nozzle inner sleeve 6 runs through and is arranged in shower nozzle 5, also comprise PEEK pipe 1, wire feed trunnion 2, ceramic insulation cotton 3, ceramic heating flake 4, the upper end of shower nozzle 5 is processed with external screw thread, and ceramic heating flake 4, ceramic insulation cotton 3 are arranged on the external screw thread of shower nozzle 5 successively; The lower end of wire feed trunnion 2 is connected with shower nozzle inner sleeve 6, and upper end is communicated with the gauge orifice in steady rest 7, and wire feed trunnion 2 is processed with external screw thread; The lower end of PEEK pipe 1 is connected with ceramic insulation cotton 3, and upper end is connected with steady rest 7; Described PEEK pipe 1 is processed with internal thread, matches with the external screw thread of wire feed trunnion 2.Ceramic heating flake 4 volume is little, lightweight, and programming rate is fast, and heating efficiency is high, the melt temperature being heated to filament-type plastic that can be very fast, reduces preheating time; Cotton 3 good heat-insulation effect of ceramic insulation, the temperature can well isolating ceramic heating flake 4 is transmitted to the component such as motor, steady rest 7.
In order to expand heating surface (area) (HS, the upper end of shower nozzle 5 and ceramic heating flake 4 are contacted.
Shower nozzle inner sleeve 6 is the long-range feed pipe of PTFE Teflon pipe, and this kind of material is high temperature resistant, and serviceability temperature can reach 260 degrees Celsius, long service life, and its effect is that guide wire material enters shower nozzle 5, and prevents silk material in this process by heating and melting.
Operation principle: steady rest 7 is fixed by screws on drive motors, the drive motors other end is connected with wire feed guide wheel mechanism, silk material enters wire feed trunnion 2 by wire feed guide wheel mechanism, under the effect of extruding force and frictional force, silk material enters printing head 5 by wire feed trunnion 2, and ceramic heating flake 4 heating and melting be rapidly fixed on printing head 5, the silk material do not heated in such wire feed trunnion 2 and ceramic heating flake 4 place molten silk material form piston action, force the silk material of molten condition to spray from shower nozzle 5.
