Abstract
The utility model discloses a prevent blockking up 3D printer and print shower nozzle, including beating printer head main part, upper portion material hole, lower part nozzle, hole under hole, the cylindrical mesopore of awl and the cylindrical buffering is gone up by cylindrical in upper portion material hole, and wherein cylindrical hole down and lower part nozzle inside are link up and is equipped with the nozzle chamber, the nozzle chamber is radius platform form, and under the radius platform of nozzle chamber the bottom surface with nozzle bore through connections, nearly 60 degrees contained angle structures of toper in the nozzle chamber, printer head expects the design in hole and the design in nozzle chamber through the air exercise to combine the structure of nearly 60 degrees contained angles of toper in the nozzle chamber, effectual problem of having determined the jam of conventional 3D print head design has improved the work efficiency of printer greatly.
Description
Technical field
This utility model relates to 3D printer printing head, particularly relates to a kind of blockage resisting 3D printer printing head.
Background technology
Existing FDM quick shaping process typically uses low melting point filamentary material, and such as PLA or ABS plastic silk, they can not
With the laser of high-energy-density as thermal source, it is only necessary to can be heated to melt by filamentary material in electrically heated mode in shower nozzle
Melt state, 3D printer of the prior art, PLA or ABS plastic in shower nozzle through high temperature melt, ejection shower nozzle after through
Shaping after cooling again, but in some special cases, cause temperature at spray outlet low, in this time, material is not also having
Have and just have cured before ejection shower nozzle completely, block shower nozzle, make the plastic wire cannot feeding forward so that the application of 3D printer
Exploitation is by significant limitation.
Utility model content
In order to overcome above-mentioned deficiency of the prior art, this utility model provides a kind of anticlogging 3D printer to print spray
Head, mainly solves the susceptible to plugging problem of 3D printer printing head in prior art.
Technical solution adopted in the utility model is: a kind of blockage resisting 3D printer printing head, including printhead master
Body, discharge opening and nozzle, wherein printhead body makes discharge opening, and discharge opening is by cylindrical upper bore, the cylindrical mesopore of cone and circle
Cylindricality buffering lower opening is constituted, and cylindrical buffer lower opening two wall is symmetrical set resistive heater, cylindrical buffer lower opening and nozzle
Internal run-through is provided with nozzle chambers.
Further, nozzle chambers shaft section two seamed edge angle is 50 °～80 °.
Further, the interior diameter of cylindrical buffer lower opening is more than the interior diameter of the cylindrical mesopore bottom of cone.
The beneficial effects of the utility model are: by the design in printhead material hole and the design of nozzle chambers so that plastics
Silk, after the cylindrical mesopore of cone is heated, will not result in blockage in hole again, and in nozzle chambers, the structure of nearly 60 degree of angles of taper makes
Obtain plastic liquid uniformly to flow out from nozzle bore, it is ensured that the reliability of shower nozzle operation, effectively solve 3D printer and print spray
Susceptible to plugging problem, substantially increases the work efficiency of printer.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model
1, printhead body 2, cone circular mesopore 3, discharge opening 4, cylindrical upper bore 5, nozzle chambers
6, nozzle 7, resistive heater 8, nozzle bore 9, cylindrical buffer lower opening
Detailed description of the invention
As it is shown in figure 1, a kind of blockage resisting 3D printer printing head described in the utility model, including printhead body 1,
Discharge opening 3 and nozzle 6, printhead body 1 makes discharge opening 3, and discharge opening 3 is by cylindrical upper bore 4, the cylindrical mesopore 2 of cone and circle
Cylindricality buffering lower opening 9 is constituted, and 9 liang of walls of cylindrical buffer lower opening are symmetrical set resistive heater 7, cylindrical buffer lower opening 9
Interior diameter (R1) is more than the interior diameter (R2) of cylindrical mesopore 2 bottom of cone.Make plastic wire after the cylindrical mesopore 2 of cone is heated,
Plastic wire expansion on taper hole wall, hole wall along its surface downward inclination at an angle to the retroaction of plastic wire surface
Power, not only reduces the frictional force formed between plastic wire and hole wall, and downward directed force F is conducive to plastic wire to nozzle
6 chambeies conveyings, will not result in blockage in hole again.Cylindrical buffer lower opening 9 and nozzle 6 internal run-through are provided with nozzle chambers 5, nozzle chambers 5
Shaft section two seamed edge angle is 60 ° so that plastic liquid uniformly flows out from nozzle bore, it is ensured that the reliability of shower nozzle operation.
The foregoing is only preferred embodiment of the present utility model, not in order to limit this utility model, all at this
Within the spirit of utility model and principle, any modification, equivalent substitution and improvement etc. made, should be included in this utility model
Protection domain within.
