Abstract
The utility model provides a sprinkler structure for 3D printer, including mount, the thermal -insulated pipe of second grade, thermal -insulated pipe, screwed pipe, heating piece and nozzle, thermal -insulated pipe is fixed on the mount, one end and screwed pipe one end that the second grade insulated against heat the pipe penetrate just in thermal -insulated intraductal being connected from the both ends of thermal -insulated pipe respectively, the other end of screwed pipe and nozzle are located in connecting the heating piece just is connected in the heating piece, thermal -insulated pipe, screwed pipe and nozzle connect and communicate in proper order. It completely cuts off to carry out the temperature through bilayer heat preservation pipe fitting to the silk material to the temperature of assurance silk material in sending the fiber tube way is less than far away melts the temperature, thereby has prevented that the silk material is because of receive high fever crystallization jam conveying pipeline way for a long time. Simultaneously set up the cooler in nozzle department, can make the printing silk that melts through nozzle blowout back, through the rapid cooling and solidification shaping of cooler. The sprinkler structure of 3D printer, the silk material is difficult block up and the shaping effectual.
Description
Technical field
The utility model relates to a kind of nozzle structure, especially a kind of nozzle structure for 3D printer.
Background technology
3D printer is also known as three-dimensional printer, it is a kind of accumulation manufacturing technology, i.e. a kind of machine of RP technique, it is a kind of based on mathematical model file, use special wax material, powdery metal or plastics etc. can jointing material, manufacture three-dimensional object by the jointing material printed from level to level.Present stage, three-dimensional printer was used to manufacture a product, and the mode that use successively prints carrys out the technology of constructed object.And based on FDM technology 3D printer run process in; because PLA silk material is when by wire feeding pipe line; heat pipe passes by length; silk material is easily long-time by high thermal crystalline; therefore silk material usually can be made before jetting nozzle to produce crystallization thus blocking conveying pipeline, thus greatly reduce the operating efficiency of equipment.Therefore need design a kind of can effectively shorten PLA silk material melt and can in the 3D printing head structure of nozzle energy fast cooling shaping.
Utility model content
The purpose of this utility model improves shower nozzle susceptible to plugging problem of structure when printing PLA material of existing 3D printer in background technology.
In order to overcome the above problems, the utility model provides a kind of nozzle structure for 3D printer, comprise secondary instlated tubular, instlated tubular, fixed mount, screwed pipe, heat block, nozzle, described instlated tubular is fixed on fixed mount, one end of described secondary instlated tubular and one end of screwed pipe penetrate from the two ends of instlated tubular respectively and are connected in instlated tubular, the other end of described screwed pipe be located at described heat block in nozzle connection and be connected in heat block, described secondary instlated tubular, screwed pipe are communicated with successively with nozzle connection.
Described fixed mount is also provided with a cooler, and air outlet and the described nozzle discharge hole of described cooler are located on same plane.
Described screwed pipe and nozzle are copper material, and described instlated tubular is PEEK polyether-ether-ketone material, and secondary instlated tubular is PTFE Teflon material.
The beneficial effects of the utility model are: at silk material interface design secondary thermal insulation protection pipeline; carry out temperature by double-layer heat insulation pipe fitting to silk material to completely cut off; thus ensure that in the wire feeding pipe line of silk material before entering screwed pipe, temperature is well below melt temperature; printed material only just starts melt and spray shower nozzle entering copper screwed pipe; by effectively shortening printed material high-temperature heating distance; reduce printed material produces crystallization risk because heating pipe line is long, thus effectively reduce the phenomenon of blocking conveying pipeline.Simultaneously cooler is set at nozzle place, the curing molding of silk material can be accelerated, prevent from printing silk material loose because of what can not get after nozzle ejection that cooling fast produces, sinking, the flaw of size distortion.The nozzle structure of 3D printer described in the utility model, silk material not easily blocks and good forming effect.

Accompanying drawing 1 is the schematic diagram of the nozzle structure of a kind of 3D printer described in the utility model.
Accompanying drawing 2 is explosive views of the nozzle structure of a kind of 3D printer described in the utility model.
Marginal data: 1, secondary instlated tubular; 2, instlated tubular; 3, fixed mount; 4, screwed pipe; 5, heat block; 6, nozzle; 7, cooler.
Detailed description of the invention
Be described further below in conjunction with the nozzle structure of accompanying drawing to a kind of 3D printer of the present utility model.
As shown in Figure 1 and Figure 2, the nozzle structure for 3D printer of the present embodiment, comprise secondary instlated tubular 1, instlated tubular 2, fixed mount 3, screwed pipe 4, heat block 5, nozzle 6, instlated tubular 2 is fixed on fixed mount 3, one end of secondary instlated tubular 1 and one end of screwed pipe 4 penetrate from the two ends of instlated tubular 2 respectively and are connected in instlated tubular 2, the other end of screwed pipe 4 be located at heat block 5 in nozzle 6 joint and be connected in heat block 5, secondary instlated tubular 1, screwed pipe 4 are communicated with successively with nozzle 6 joint.Because PLA silk material is passing through in wire feeding pipe line process because of the long-time characteristic being subject to Gao Reyi crystallization; silk material usually can be made to melt post crystallization thus blocking conveying pipeline; enter copper trunnion advance trip temperature by double thermal insulation pipe fitting to silk material to completely cut off; thus shorten silk material and to be heated distance; thus not easily reach crystalline state; ensure that silk material not easily produces crystalline polamer in wire feeding pipe line, preventing silk material in wire feeding pipe line because being subject to high thermal crystalline for a long time thus blocking conveying pipeline.During operation; the conveying pipeline of silk material is connected with secondary instlated tubular, and instlated tubular and secondary instlated tubular double thread pipe carry out thermal insulation protection, and silk material arrives nozzle connection through conveying pipeline, secondary instlated tubular, screwed pipe; steady heat melt material is started, then from nozzle steady extruding in screwed pipe.
In the present embodiment, fixed mount 3 is also provided with a cooler 7, air outlet and nozzle 6 discharging opening of cooler 7 are located on same plane.After silk material is sprayed by nozzle, the printing silk curing molding that cooler will melt rapidly, accelerates the shaping of 3D object.
In the present embodiment, screwed pipe 4 and nozzle 6 are copper material, and secondary instlated tubular is PTFE Teflon material, and instlated tubular 2 is PEEK polyether-ether-ketone material.Copper has good thermal conductivity, silk material can be made to melt rapidly through screwed pipe, and spray rapidly in nozzle.PEEK and PTFE material has good heat-blocking action, makes silk expect not easily Crystallization Plugging pipeline.The nozzle structure of the 3D printer of the present embodiment, silk material not easily blocks and good forming effect.
Above-described specific embodiment; the purpose of this utility model, technical scheme and beneficial effect are further described; be understood that; the foregoing is only specific embodiment of the utility model; be not limited to the utility model; all within spirit of the present utility model and principle, any amendment made, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
