Abstract
The utility model discloses a kind of 3D printer nozzle arrangements, its key is：The structure includes cylindrical hollow body, and the body bottom portion is connected with feed nozzle, and body surrounding uniform intervals are provided with multiple perpendicular strip grooves；Body exterior, which is arranged with heater, the inner surface of heater, is provided with multiple hollow boss, and heating element heater is provided with inside the hollow space and vertical bar shape hollow boss of the heater；Ring-type heat-proof device is also arranged with outside the heater, multiple fin are evenly arranged with the heat-proof device outer surface.The utility model realizes the uniform heating to heating material in body, meanwhile, also by adding multiple fin on outside heat-proof device so that heat-proof device outside heat meeting quick release, prevent because the too high damage caused to nozzle arrangements of temperature；Its design principle is simple, the homogeneous heating effect of nozzle arrangements can be greatly lifted, moreover it is possible to more rapidly realize heat sinking function, with very strong practical value.
Description
Technical field
The utility model is related to a kind of 3D printer nozzle arrangements.
Background technology
3D printer is a kind of printing modelling apparatus popular in recent years, and be gradually promoted to manufacture field should
With.In 3D printer, nozzle arrangements are mainly used in spraying the printed material of heating and melting, and in the effect of control device
Under successively printing shaping.The heater being arranged outside existing nozzle arrangements only connects with the outer surface of nozzle arrangements mostly
Touch, but the printed material inside nozzle arrangements is that have certain thickness, therefore, in heating process, often there is heating
Material degree of heat in not uniform enough the problem of, nozzle close to core is lower than the material degree of heat of marginal portion,
This can cause to occur being molded the problem of irregular finished product that is equal, printing is rough fine and smooth during last printing.
Utility model content
The purpose of this utility model is to provide a kind of 3D printer nozzle arrangements.
To achieve these goals, using following technical scheme：A kind of 3D printer nozzle arrangements, it is characterised in that：Institute
Stating 3D printer nozzle arrangements includes cylindrical hollow body, and the body bottom portion is connected with the feed nozzle of turbination, described
Body surrounding uniform intervals are provided with multiple perpendicular strip grooves to body sunken inside；The body exterior is arranged with hollow ring-type
Multiple vertical bar shapes adaptable with perpendicular strip groove on body are provided with heater, the inner surface of the heater hollow
Heating element heater is provided with inside projection, the hollow space and vertical bar shape hollow boss of the heater；Outside the heater
Portion is also arranged with ring-type heat-proof device, and multiple fin were evenly arranged with around peripheral one week on the heat-proof device outer surface.
The groove set on the body has six.
The hollow boss set on the heater also has six.
The fin set on the heat-proof device has eight.
The heat-proof device is internally provided with heat-barrier material.
The heat-barrier material is asbestos.
Heater is extend into the groove of body by the utility model, realizes and the uniform of heating material in body is added
Heat, meanwhile, also by adding multiple fin on outside heat-proof device so that heat-proof device outside heat meeting quick release,
Prevent because the too high damage caused to nozzle arrangements of temperature；Its design principle is simple, can greatly lift adding for nozzle arrangements
Hot even results, moreover it is possible to more rapidly realize heat sinking function, with very strong practical value.

Fig. 3 is the sectional view in Fig. 2 along line A-A；
Fig. 4 is the top view of heater in Fig. 1；
Fig. 5 is the top view of heat-proof device in Fig. 1.
Embodiment
The utility model is described further with specific embodiment below in conjunction with the accompanying drawings.
As shown in Figures 1 to 5, a kind of 3D printer nozzle arrangements, including cylindrical hollow body 1, the bottom of body 1 connects
The feed nozzle 2 of turbination is connected to, it is recessed that the surrounding uniform intervals of body 1 are provided with multiple vertical bar shapes to the sunken inside of body 1
Groove 101；The outer cover of body 1 is provided with hollow annular heating device 3, is provided with the inner surface of the heater 3 multiple
The adaptable vertical bar shape hollow boss 301 with perpendicular strip groove 101 on body 1, the hollow space of the heater 301 and perpendicular
Heating element heater is provided with inside strip hollow boss 301；Ring-type heat-proof device 4 is also arranged with outside the heater 3, should
On the outer surface of heat-proof device 4 multiple fin 401 were evenly arranged with around peripheral one week.
The groove 101 set on the body 1 has six.
The hollow boss 301 set on the heater 3 also has six.
The fin 401 set on the heat-proof device 4 has eight.
Heat-barrier material 402 is provided with the inside of heat-proof device 401.
The heat-barrier material 402 is asbestos.
In the utility model specific embodiment structure, due to be provided with body it is multiple towards body interior be recessed
Groove so that the Hollow raised section on heater can be stretched into groove.When the heating element heater set in heater is opened
Begin perform heating operation when, heater not only can by its inner surface to nozzle body outer surface transmit heat, realize pair
The heating operation of printed material in nozzle body, at the same time it can also by the heating element heater in hollow boss on body
Groove inner wall transmits heat so that being especially located at the printed material close to center part inside nozzle body can also obtain
Synchronous Heating effect, the final printed material for make it that feed nozzle sprays is uniform, is brought in the absence of because of heating irregular
Uneven, the rough problem of shaping.
At the same time, heat-proof device can be good at the heat completely cut off produced by heater, prevents heat from leaking, enters one
Step ensures the heating effect of heater.And the fin set on heat-proof device outer surface, heat-proof device can be will transmit through
Heat quickly volatilizees, it is ensured that the stability of nozzle arrangements work.
In design, in order to ensure the close connection between body, heater and heat-proof device, the external diameter of body will be with
The internal diameter of heater is adapted, and the external diameter of heater will be adapted with the internal diameter of heat-proof device.
In a particular embodiment, the heating element heater employed in heater is high-temperature electric heated filament or high-temperature electric hot pin.
Heater is extend into the groove of body by the utility model, realizes and the uniform of heating material in body is added
Heat, meanwhile, also by adding multiple fin on outside heat-proof device so that heat-proof device outside heat meeting quick release,
Prevent because the too high damage caused to nozzle arrangements of temperature；Its design principle is simple, can greatly lift adding for nozzle arrangements
Hot even results, moreover it is possible to more rapidly realize heat sinking function, with very strong practical value.
