Abstract
The invention discloses a 3D printer nozzle. The nozzle comprises a discharge cylinder and a shell. The external round surface of the discharge cylinder is provided with a thermal conductive layer; multiple heating rings are sleeved on the thermal conducive layer, and the heating rings are arranged in the shell. One end of the discharge cylinder is fixedly connected to a discharge head, and the other end is fixedly connected to a feed head. The heating rings are parallelly and sequentially sleeved on the external round surface of the discharge cylinder, and are connected to an electric control box through a circuit individually. The provided 3D printer nozzle can avoid nozzle obstruction, which may affect the quality of printed models.
Description
Technical field
The present invention relates to 3D printer technology field, in particular to a kind of shower nozzle of 3D printer.
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 the nozzle structure of 3D printer, 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 shower nozzle of 3D printer, to solve the deficiencies in the prior art.
For realizing the object of the invention, the technical scheme of employing is:
A shower nozzle for 3D printer, comprises 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.
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, also prevented the waste of heater heat in addition by housing, can also prevent from scalding staff.
Accompanying drawing explanation
Fig. 1 is the structural representation of the shower nozzle of a kind of 3D printer 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.
Fig. 1 the is shown shower nozzle of a kind of 3D printer provided by the invention, comprising: housing 1, feed head 2, heating ring 3, heat-conducting layer 4, discharge barrel 5, discharge head 6, sealing ring 7.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.
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 8 meltings are uneven or produce the phenomenon of bubble and prevent from blocking the phenomenon of discharge head 6 to avoid silk to expect.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 8 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.
The foregoing is only the preferred embodiments of the present invention, be not limited to the present invention, for a person skilled in the art, the present invention can have various modifications and variations.Within the spirit and principles in the present invention all, any amendment done, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
