Seeing Fig. 3,3D printing pen and also include that nib shell 12, nib shell 12 are arranged on the first end of shell 1, nozzle 3 is arranged In nib shell 12, fixed component 4 is arranged on shell 1 and nib shell 12 junction.Alternatively, nib shell 12 can be and shell The 1 fixing single parts connected, it is also possible to be shell 1 and integrated structure.

3D prints the shell 1 of pen and is internally provided with elastomeric element 71, plate washer the 75, first limiting component the 72, second limiting section Part 73 and the 3rd limiting component 74.Preferably, elastomeric element is spring.It is spacing that the two ends of elastomeric element 71 are connected to first respectively Between parts 72 and plate washer 75, the first limiting component 72 and the second limiting component 73 are arranged at the 3rd limiting component 74 and plate washer 75 Between, and the first limiting component 72 is arranged between the second limiting component 73 and the 3rd limiting component 74.When carrying out the conveying of silk material, Silk material conveying active force synchronization is in nozzle 3, and the first limiting component 72 drives nozzle 3 to print the opening 11 direction fortune of pen to 3D Dynamic, until the first limiting component 72 abuts with the second limiting component 73, now nozzle 3 is from the opening of the first end being positioned at shell 1 11 stretch out；When stopping silk material and carrying and retract, elastomeric element 71 has reaction force to the first limiting component 72, pushes away Dynamic first limiting component 72 internal motion towards shell 1, until the first limiting component 72 contacts with the 3rd limiting component 74, this Time nozzle 3 retract in shell 1.

Seeing Fig. 3 and Fig. 4, being shaped as annular or have the annular of opening of fixed component 4 cross section, fixed component 4 is overlapped It is located on shell 1.When the cross section of fixed component 4 is to have opening annular, fixed component 4 is in the circumferential halfway around outward The periphery wall of shell 1.Alternatively, fixed component 4 can be the single parts being set on shell 1, it is also possible to is and shell 1 one Body formed, be formed as diametrically from the projection outwardly extended of shell 1.

See Fig. 5, Fig. 6 and Fig. 8, the circumference of fixed component 4 offers gathering sill 41, be provided with in gathering sill 41 and lead Electricity parts (not shown), the first end of mobile parts 5 is provided with the holding section 51 coordinated with gathering sill 41, holding section 51 and conduction Parts electrically connect.Gathering sill 41 includes that receiving portion 411 and extension 412, receiving portion 411 are on the periphery wall of fixed component 4 The groove formed, and the opening direction of groove is along fixed component 4 radially outward, the two side of groove has along fixed component The extension 412 extended axially inwardly.Seeing Fig. 4, the holding section 51 of mobile parts 5 is the shape coordinated with gathering sill 41, makes Mobile parts 5 can slide and without departing from gathering sill 41 in gathering sill 41.

Seeing Fig. 8, the second end of mobile parts 5 is provided with spherical guide part 52, chiller 6 offers and guides The spherical groove 61 that portion 52 matches, guide part 52 inserts and is connected to by chiller 6 in spherical groove 61 on mobile parts 5.

The 3D of the present embodiment prints the work process of pen and is described as follows.First, press control knob 21,22, nozzle 3 from The opening 11 of the first end of shell 1 stretches out；After silk material is heated to form molten condition, under the effect of follow-up silk material thrust, will be molten The silk material melting shape is extruded by nozzle 3, and hand-held 3D printing pen moves and prints；Chiller 6 is to nozzle 3 or the silk material of extrusion Cool down；Then, pressing control knob 21,22 again, silk material stops conveying and retreats, and stops printing, outside nozzle 3 returns to The inside of shell 1;Stopping heating nozzle 3, chiller 6 quits work, and stops cooling down nozzle 3.

3D prints pen the second embodiment:

As the explanation of this utility model printhead the second embodiment, the most only print a first embodiment to above-mentioned 3D Difference be explained.

Seeing Fig. 7, the shape that fixed component 14 coordinates with mobile parts 15 can also be arranged to following structure.Wherein, Gu The gathering sill 141 of limiting-members 14 include upper groove 1411, the structure of low groove 1412, upper groove 1411 and low groove 1412 around Two ends of fixed component 14 are offered and be respectively arranged to the circumference of fixed component 14, and the holding section 151 of mobile parts 15 has In having upper protruding 1511 and lower convexity 1512, upper protruding 1511 to be arranged on upper groove 1411 and can slide in upper groove 1411, In lower convexity 1512 is arranged on low groove 1412 and can slide in low groove 1412, i.e. moving parts 15 can be around fixed component 14 Circumferentially rotate.

Therefore, chiller is connected to 3D by mobile parts and fixed component and prints pen, and chiller can be with shifting Dynamic component rotating in a circumferential direction around shell, chiller also can rotate around mobile parts simultaneously, and this kind of structure can be adjusted flexibly cooling Device prints the angle of pen relative to 3D, is conveniently adjusted the position of chiller as required.After pressing control knob, Electric current flows through fixed component and the motor moved in parts are finally supplied to chiller successively, rotates after cooling fan energising, Being discharged from air outlet by cold wind, while printing three-dimensional body, chiller can be by being adjusted to different angles and side Position realizes cooling down around the diverse location to the three-dimensional body printed or nozzle-end and nozzle, so piles up The object of molding can solidify under the effect of material self plasticity, and keeps certain shape, can reduce around nozzle simultaneously Temperature, thus realize good radiating effect, make the silk material of molten condition solidify as early as possible after nozzle is extruded, improve and print essence Degree, this structure is easy to dismounting, convenient use simultaneously.Carry out piling up or outstanding it addition, chiller can print pen at 3D Start working during hollow structure, when need not cooling, rotary cooling device, make chiller misalignment nozzle or pressing cooling dress Putting control knob makes chiller quit work.

Finally it is emphasized that this utility model is not limited to above-mentioned embodiment, as fixed component is joined with mobile parts The change etc. closing the change of shape, fixed component shape of cross section changes the guarantor that also should be included in this utility model claim In the range of protecting.
