Abstract
The invention discloses an anti-obstruction 3D printer nozzle structure. The structure comprises a discharging cylinder and a shell; the external round surface of the discharging cylinder is provided with a thermal conductive layer, a plurality of heating rings are sleeved on the thermal conductive layer, and the heating rings are installed in the shell. One end of the discharging cylinder is fixedly connected to a discharge head, and the other end is fixedly connected to a feed head. The heating rings are sequentially and parallelly sleeved on the external round surface of the discharging cylinder and individually connected to an electric cabinet through circuits. A rotation shaft is arranged in the discharging cylinder, goes through one side of the discharging cylinder, and is connected to a motor. A stirring section and a feed section are arranged on the rotation shaft in the direction from motor to the tail end of the rotation shaft, wherein the stirring section of the rotation shaft is composed of a plurality of blades, and the feed section is composed of screw threads. The provided anti-obstruction 3D printer nozzle can avoid nozzle obstruction which may affect the printing effect.
Description
Technical field
The present invention relates to 3D printer technology field, in particular to one anticlogging 3D printer head structure.
Background technology
3D printer is also known as three-dimensional printer, a kind of accumulation manufacturing technology, i.e. a kind of machine of RP technique, it is based on a kind of 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.The mode successively printed carrys out the technology of constructed object.The principle of 3D printer is that data and raw material are put in 3D printer, and machine can be created product from level to level according to program.
The heat block for heater strip material is generally had in anticlogging 3D printer head structure structure, but due to generally independently heating component can be arranged in heat block, by heating component, heat block heated thus melt silk material, but temperature distributing disproportionation is even in existing heat block, the silk material in shower nozzle is caused to melt also unshapeliness, occur block, thus shower nozzle or printer model weak effect may be blocked.
Summary of the invention
The object of the present invention is to provide a kind of anticlogging 3D printer head structure, to solve the deficiencies in the prior art.
For realizing the object of the invention, the technical scheme of employing is:
A kind of anticlogging 3D printer head structure, comprise discharge barrel and housing, it is characterized in that, the periphery of described discharge barrel is provided with heat-conducting layer, and on heat-conducting layer, cover has some heating rings, and heating ring is arranged in housing; Described discharge barrel one end is fixedly connected with discharge head, and the other end is fixedly connected with feed head; Described each heating ring is enclosed within the periphery of discharge barrel successively side by side, and is connected with electric cabinet respectively by circuit; Be provided with rotating shaft in described discharge barrel, rotating shaft is connected with motor through discharge barrel side, and rotating shaft is set to successively along motor to shaft end direction stirs section and feeding section; The stirring section of described rotating shaft is multiple blade, and its feeding section is screw thread.
Further, the inner surface of the periphery of described discharge barrel and housing, discharge head and feed head form seal cavity.Be conducive to avoiding the too fast loss of heat, waste energy.
Further, in the charging hole of described feed head, be provided with the sealing ring coordinated with charging hole, avoid the silk material under molten condition to flow backwards, cause waste.
The invention has the beneficial effects as follows,
One, compared with prior art, each heating ring is connected by circuit with electrical control cubicles respectively; And each heating ring is set on discharge barrel successively side by side.Controlled the caloric value of each heating ring by electric cabinet respectively, thus realize carrying out Discrete control to the temperature in discharge barrel according to actual needs, thus avoid the melting of silk material uneven or produce the phenomenon of bubble and prevent from blocking the phenomenon of discharge head.
Two, be arranged on heat-conducting layer by each heating ring, heat-conducting layer is enclosed within discharge barrel, heat is distributed due to heat-conducting layer evenly, make discharge barrel internal thread material keep molten condition, avoid silk material to block discharge head because of solidification, simple and practical, increase the service life.
Three, stirred the silk material melted by stirring vane, make it be in complete molten condition fast, avoid heating that silk can not be made to expect quick and complete melting, cause the threedimensional model poor quality printed.The silk material being promoted molten condition by screw thread is exported, and avoids occurring clogging.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of anticlogging 3D printer head structure provided by the invention.
Detailed description of the invention
Also by reference to the accompanying drawings the present invention is described in further detail below by specific embodiment.
One provided by the invention anticlogging 3D printer head structure that Fig. 1 is shown, comprising: housing 1, feed head 2, heating ring 3, heat-conducting layer 4, discharge barrel 5, discharge head 6, charging aperture 18, motor 14, rotating shaft 15, blade 16 and screw thread 17.The periphery of described discharge barrel 5 is provided with heat-conducting layer 4, and on heat-conducting layer 4, cover has some heating rings 3, and heating ring 3 is arranged in housing 1; Described discharge barrel 5 one end is fixedly connected with discharge head 6, and the other end is fixedly connected with feed head 2; Described each heating ring 3 is enclosed within the periphery of discharge barrel 5 successively side by side, and is connected with electric cabinet respectively by circuit; Be provided with rotating shaft 15 in described discharge barrel 5, rotating shaft 15 is connected with motor 14 through discharge barrel 5 side, and rotating shaft 15 is set to successively along motor 14 to rotating shaft 14 end direction stirs section and feeding section; The stirring section of described rotating shaft 15 is multiple blades 16, and its feeding section is screw thread 17.
The periphery of discharge barrel 5 and the inner surface of housing 1, discharge head 6 and feed head 2 form seal cavity.Be conducive to avoiding the too fast loss of heat, waste energy.Be provided with the sealing ring 7 coordinated with charging hole in the charging hole of feed head 2, avoid the silk material under molten condition to flow backwards, cause waste.
By each heating ring 3 is connected by circuit with electrical control cubicles respectively; And each heating ring 3 is set on discharge barrel 5 successively side by side.Controlled the caloric value of each heating ring 3 by electric cabinet respectively, thus realize carrying out Discrete control to the temperature in discharge barrel 5 according to actual needs, thus avoid the melting of silk material uneven or produce the phenomenon of bubble and prevent from blocking the phenomenon of discharge head 6.Be arranged on heat-conducting layer 4 by each heating ring 3, heat-conducting layer 4 is enclosed within discharge barrel 5, heat is distributed due to heat-conducting layer 4 evenly, discharge barrel 5 internal thread material is made to keep molten condition, silk material is avoided to block discharge head 6 because of solidification, simple and practical, increase the service life.Also prevented the waste of heater heat in addition by housing 1, can also prevent from scalding staff.Stirred the silk material melted by stirring vane 16, make it be in complete molten condition fast, avoid heating that silk can not be made to expect quick and complete melting, cause the threedimensional model poor quality printed.The silk material being promoted molten condition by screw thread 17 is exported, and avoids occurring clogging.
