Description
Technical field
The utility model relates to 3D printer technology field, relates in particular to a kind of printhead nozzle component of 3D printer.
Background technology
As shown in Figure 1, the printhead nozzle component of existing 3D printer comprises: the nozzle 12 being connected for delivery of the charging trunnion 11 of printed material, with charging trunnion 11 and be placed in charging trunnion 11 and the heat block 13 of nozzle 12 connecting portion outsides.Wherein, the inner tube of the inner tube of charging trunnion 11 and nozzle 12 is communicated with, and heat block 13 will be placed in the printed material thermoplastic of charging trunnion 11 inner tubes and nozzle 12 inner tubes, and sprays from the discharging opening of nozzle 12, realizes the printing of article.Charging trunnion 11 is stainless steel tube, and nozzle 12 is copper nozzle, and heat block 13 is aluminium heat block.
Charging trunnion 11 and nozzle 12 are threaded connection in heat block 13.Heat block 13 can heat nozzle 12 and charging trunnion 11 simultaneously.Printed material can soften expansion in the time entering charging trunnion 11, and because charging trunnion 11 inwalls are rough, frictional force is large, and printed material can get lodged in the junction of charging trunnion 11 and nozzle 12, causes 3D to print that wire vent has some setbacks or the situation of nozzle plug.Even, the residual printed material of junction possibility of charging trunnion 11 and nozzle 12, residual printed material at high temperature can carbonization form impurity, causes nozzle plug.Now, 3D printer must be pulled down nozzle cleaning impurity or change nozzle and could continue to use.
Utility model content
For this reason, technical problem to be solved in the utility model is: a kind of printhead nozzle component of 3D printer is provided, makes printed material nonchoking nozzle.
So, the utility model provides a kind of printhead nozzle component of 3D printer, comprise charging trunnion and the nozzle being connected with charging trunnion, charging trunnion inner tube and nozzle inner tube are communicated with, the good passage of lubricity for delivery of printed material of one perforation feed throat pipe inner tube and nozzle inner tube wherein, is set in charging trunnion and nozzle inner tube.
Wherein, described passage is the good passage of lubricity of PTFE material.
Described charging trunnion charging aperture place is provided with is convenient to print the chamfering that wire rod inserts.
The downward caliber in described charging trunnion chamfering place is convex structure, and passage just embeds and be fastened on the bottom of charging trunnion convex structure, and in charging trunnion convex structure top, in caliber and passage, caliber is identical and connect.
There is fin in charging trunnion outer setting.
Described feed throat tube outer surface is convex-concave fin shape.
Described charging trunnion and nozzle are threaded connection.
There is heat block in nozzle outer setting.
Described heat block and the nozzle structure that is formed in one.
The printhead nozzle component of 3D printer described in the utility model, by the good passage of the lubricity for delivery of printed material of a perforation feed throat pipe inner tube and nozzle inner tube is set in charging trunnion and nozzle inner tube, the drawback that has overcome printed material plug nozzle, has realized printed material nonchoking nozzle.
Further, overcome described in background technology and heat block has been arranged on to nozzle and charging pipe joint, printed material softens in advance the drawback expanding in charging trunnion.
Further, be set to convex-concave fin shape at charging trunnion outer setting fin or feed throat tube outer surface, the heat that heat block can be conducted by charging trunnion dissipates as early as possible, avoids the printed material in charging trunnion softening in advance.
Brief description of the drawings
Fig. 1 is the printhead nozzle component structural representation of 3D printer in prior art;
Fig. 2 is the printhead nozzle component structural representation of 3D printer described in the utility model embodiment.
Detailed description of the invention
Below, by reference to the accompanying drawings the utility model is described in detail.
As shown in Figure 1, the present embodiment provides a kind of printhead nozzle component of 3D printer, comprise: charging trunnion 21 and the nozzle being connected with charging trunnion 21, charging trunnion inner tube and nozzle inner tube are communicated with, and the good passage 23 of the lubricity for delivery of printed material of a perforation feed throat pipe inner tube and nozzle inner tube is set in charging trunnion and nozzle inner tube.
Wherein, passage 23 is PTFE(Polytetrafluoroethene, polytetrafluoroethylene (PTFE)) the good passage of lubricity of material.
Insert for ease of passage, charging trunnion 21 charging aperture places can be arranged to chamfering, as shown in arrow in figure 24.The downward caliber in described charging trunnion 21 chamfering places 24 is " protruding " character form structure, passage 23 just embeds and is fastened on the bottom of charging trunnion 21 " protruding " character form structure, in charging trunnion 21 " protruding " shape structure top caliber identical with the interior caliber of passage 23 and connect.
Dissipate as early as possible for ease of the heat that heat block is transmitted by charging trunnion, avoid printed material softening in advance, can be set to convex-concave fin shape at charging trunnion 21 outer setting fin or charging trunnion 21 outer surfaces.The present embodiment adopts charging trunnion 21 outer surfaces to be set to convex-concave fin shape.
Charging trunnion 21 directly can be connected by screw thread 25 with nozzle 22.
Heat block 26 is arranged on nozzle 22 outsides by the present embodiment, overcome described in background technology and heat block has been arranged on to nozzle and charging pipe joint, and printed material softens in advance the drawback expanding in charging trunnion.Wherein, heat block and nozzle also can be formed in one structure.
In sum, the printhead nozzle component of 3D printer described in the present embodiment, by the good passage of the lubricity for delivery of printed material of a perforation feed throat pipe inner tube and nozzle inner tube is set in charging trunnion and nozzle inner tube, the drawback that has overcome printed material plug nozzle, has realized printed material nonchoking nozzle.
Further, heat block is arranged on to nozzle outside, has overcome and described in background technology, heat block has been arranged on to nozzle and charging pipe joint, printed material softening drawback in advance in charging trunnion.
Further, be set to convex-concave fin shape at charging trunnion outer setting fin or feed throat tube outer surface, the heat that heat block can be conducted by charging trunnion dissipates as early as possible, avoids printed material softening expansion the in advance in charging trunnion.
