Abstract
The invention discloses a spray head device of a 3D printer. A feeding slope which forms a certain inclination with a spray head main body is arranged at the upper end of a spray head so as to limit the width of a plurality of strip-shaped feeding ports in the feeding slope and then ensure that the diameter of a nozzle of the fine spray head is larger than the width of the plurality of strip-shaped feeding ports in the feeding slope. According to the spray head device of the 3D printer, the condition that the spray heads of the existing 3D printers are blocked by the granular impurities in threadlike hot melting materials due to the arrangement of fine nozzles is changed. The threadlike hot melting materials enter the inner cavity of the spray head after hot melting and is extruded by the spray head of the fine nozzle, so that the granular impurities greater than or equal to the diameter of the nozzle of the spray head are intercepted outside the strip-shaped feeding ports.
Description
Technical field
The present invention relates to RP technique field, be specifically related to a kind of 3D printer head device.
Background technology
3D printer is a kind of based on mathematical model file, uses plastics etc. can jointing material, is carried out the technology of constructed object by the mode successively printed.
Be widely used for the primary mold manufacture of the industrial circle such as Making mold, industrial design, the direct manufacture of some products just gradually; The consciousness being applied to DIY just gradually realizes, and the copying of toy.
Existing 3D printer technology content, gushes out thread heat-fusible materials heating and melting by squeezing with the shower nozzle of a minute nozzle to the manipulation of 3D printer primarily of: Input Software data command.From shower nozzle ejection after hot melt material fusing, be deposited on the material of print job deck plate or oneself solidification of front one deck, temperature, lower than starting solidification after solidification temperature, forms final finished by the accumulation layer by layer of material.
The advantage of 3D printer is to manufacture simply, and operation maintenance becomes wood cheap, but current 3D printer ubiquity very large defect, directly affects the sale of 3D printer with universal.
Extrude nozzle component blockage problem:
People admit substantially, the common wire leading pipe of 3D printer is made up of metal material, wire leading pipe one end (wire outlet end) connects heater block and nozzle, due to the good conductor that metal is heat, cause the wire inlet end temperature of wire leading pipe too high, cause fuse softening in wire leading pipe, result in blockage and cannot continue into silk, finally cause printing and interrupt.
So technological improvement insulation bushing guiding, be increased to the active force of heater block and nozzle segment, but shower nozzle blockage problem still exists.
The basic reason of 3D printer head blocking is: thread heat-fusible materials heating and melting, by squeezing the process gushed out with the shower nozzle of a minute nozzle.
1. thread heat-fusible materials---heat-fusible materials is when being processed to thread, technique through raw material shape changes, in hot melt manufacture process, in the material mixing of hot melt manufacture is added, cannot invariably be mingled with particulate contamination, particulate contamination diameter is different.
2. the shower nozzle of minute nozzle squeezes ejection material---in order to reach higher precision, 3D printer head is equipped with the shower nozzle of minute nozzle, retention particulate contamination in the working condition of fine shower nozzle and thread heat-fusible materials, forever inevitably in the blocking forming 3D printer head.
Shower nozzle blocking again and again, so that there is the specific purpose tool of special dredging 3D printer head in Taobao, directly raise the professional requirement to 3D printer operation technique personnel, make the Technical comparing owing to relating to complicated, maintenance cost increases, and range of application also just narrowly can only concentrate on high-end manufacture field.
Summary of the invention
In view of the deficiencies in the prior art, the present invention proposes a set of solution, provides a kind of 3D printer head device.
Technical scheme is as follows:
Content described in 3D printer head device comprises: having in shower nozzle upper end with nozzle body is the charging inclined-plane of constant slope, charging inclined-plane has many strips charging aperture; At shower nozzle threaded upper ends, place leaves the hole through with nozzle cavity.
Beneficial effect of the present invention:
The present invention is with the restriction to the many strips charging aperture width on charging inclined-plane, the nozzle diameter of fine shower nozzle is made to be greater than many strips charging aperture width on charging inclined-plane, can allow after thread heat-fusible materials hot melt, enter nozzle cavity, ejection material is squeezed by the shower nozzle of minute nozzle, and be greater than, equal the particulate contamination of spray nozzle diameter, be then trapped within outside strip charging aperture.
The angle rational design of strip charging aperture on charging inclined-plane, ensure that the flowing of thread heat-fusible materials and the transmission of extrusion power.
Charging inclined-plane, effectively to the retention particulate contamination rested in strip charging aperture heat-fusible materials, because being subject to thread heat-fusible materials extrusion power, and being eliminated and moving.
At shower nozzle threaded upper ends, place leaves the hole through with nozzle cavity, can reduce technological requirement when welding shower nozzle upper end and charging inclined-plane, and the requirement that the finished product that can meet nozzle cavity part is clean.

Detailed description of the invention
In order to make object of the present invention, technical scheme and advantage clearly understand, below in conjunction with accompanying drawing 1, Fig. 2, Fig. 3, Fig. 4, the present invention is further elaborated.
A kind of 3D printer head device, having with nozzle body in nozzle body (1) upper end is the charging inclined-plane (3) of constant slope, charging inclined-plane (3) has many strips charging aperture (6); The lancing door (4) through with nozzle cavity (8) is left at nozzle body (1) threaded upper ends (2) place.
The width of the many strips charging aperture (6) on charging inclined-plane (3), be less than the diameter of nozzle body (1) lower end nozzle (5), after thread heat-fusible materials hot melt, flow into nozzle cavity (8) by extrusion power, squeeze ejection material by the upper minute nozzle (5) of nozzle body (1).
In thread heat-fusible materials, be greater than, equal the particulate contamination of spray nozzle (5) diameter, be then trapped within strip charging aperture (6) outward.
The angle of strip charging aperture (6) on charging inclined-plane (3) is rational design, and after ensure that thread heat-fusible materials hot melt, mobility direction coincide and the transmission of extrusion power.
By by thread heat-fusible materials extrusion power, charging inclined-plane (3) rest on the heat-fusible materials interior retention particulate contamination at strip charging aperture (6) place, be eliminated and move.
The lancing door (4) through with nozzle cavity (8) is had at nozzle body (1) threaded upper ends (2) place, by the lancing door (4) of the many multiples of diameter and nozzle (5) diameter, technological requirement when welding nozzle body (1) upper end and charging inclined-plane (3) can be reduced, and the clean requirement to finished product nozzle body (1) upper nozzle inner chamber (8) part can be met.
, there is polyhedron nut shape (7) upper screw thread (2) lower end of nozzle body (1), is convenient to nozzle body (1) and 3D printer module screw thread to coincide fixing.
Because the upper screw thread (2) of nozzle body (1) coincide fixing with 3D printer module screw thread, lancing door (4) closes, and nozzle cavity (8) enclosure space is set up.
In this description, the present invention is own is described with reference to its specific embodiment.But, still can make various amendment and conversion obviously and not deviate from the spirit and scope of the present invention.Therefore, description and accompanying drawing are regarded in an illustrative, rather than a restrictive.
