A kind of 3D printer port of printer with heat dissipation wind channel
Technical field
The utility model relates to printer, especially a kind of 3D printer port of printer with heat dissipation wind channel.
Background technology
3D printer is the printing utensil of physical model the Computerized three-dimensional data transformations that designs a model, current fusion sediment Modeling Technology is the main flow printing technique of 3D printer, the formed precision of this technology is except affecting by transmission accuracy, also the impact of feed precision is subject to a certain extent, because the nozzle of printhead is very near apart from printhead feed cavity, high temperature during material molten easily reaches in printhead cavity by printhead shell, as too high in printhead cavity temperature, then printed material will start to soften at the place of feed portion of printhead, feed precision is affected and then has influence on the formed precision of printer, if printed material is because printhead high temperature is in place of feed portion generation thawing phenomenon, material after then melting is easy to block printhead, printer is made to produce fault.How under the prerequisite not affecting printhead original function, improving the heat radiation of 3D printer port of printer, is a research direction.
A kind of many heat abstractors of 3D printer are disclosed in the patent of publication number 203651217U, it is dispelled the heat by the shell of fan to printhead, but this radiating mode is only for printhead outer surface, do not form radiating airflow in printhead inside, when the wall of printhead shell is thicker, easily making inside and outside printhead shell uneven in temperature, still may there is superheating phenomenon in printhead inside.
Summary of the invention
The utility model proposes a kind of 3D printer port of printer with heat dissipation wind channel, the printhead heat radiation of energy efficient hardening 3D printer.
The utility model adopts following scheme.
A kind of 3D printer port of printer with heat dissipation wind channel, comprise print head body, described printhead is provided with the heat dissipation wind channel of cavity and ft connection, described printhead comprises radiator fan, feed portion, nozzle, printhead shell, described feed portion is located in printhead, nozzle is located at printhead bottom, described printhead side wall of outer shell place is provided with fan through hole, fan through hole is located at by described radiator fan, printer casing sidewall is fixed on Easy-dismounting structure, radiator fan wind direction is towards feed portion, printhead shell is also provided with air channel through hole, described heat dissipation wind channel comprises radiator fan, printhead cavity, fan through hole and air channel through hole.
Described fan through hole is radiating airflow upstream end.
Described upper end of nozzle is connected with trunnion, and trunnion stretches in printhead cavity, and trunnion initiating terminal is adjacent with feed portion, and end is fixedly connected with nozzle, and the trunnion tube wall in printhead cavity is connected with radiating block, and described radiating block is with metal material moulding.
Described nozzle is provided with forming materials cooling fan on one side, and forming materials cooling fan is positioned at the side that printhead is provided with the outer wall of air channel through hole, and its fan wind is to towards nozzle.
Described radiator fan place is provided with Air Filter.
Described radiator fan is provided with fan failure alarm device.
Printer casing of the present utility model offers fan through hole and air channel through hole, feed portion is located in printhead, fan through hole is located at by radiator fan, radiator fan wind direction is towards feed portion, this structure makes radiator fan, fan through hole, printhead cavity, air channel through hole constitute a complete air channel, cool exterior air can directly enter printhead cavity, is the printed material heat radiation in feed portion and cavity, makes printed material not easily occur because of overheated softening or melt.
The utility model adopts radiator fan to carry out active heat removal, and wind direction is towards printhead cavity, the blast that fan produces can make the cold air of feeding mineralization pressure inside and outside printhead poor, namely the air pressure in printhead is greater than outside printhead, this makes radiating airflow while flowing out from air channel through hole, also printhead cavity can be entered with in outside other space communicated, as printed material input hole, nozzle bore etc., effectively improve heat radiation, and the hot-air that its inner and outer air pressure difference also makes nozzle exit fusion sediment material be formed not easily imports in printhead cavity into.
Upper end of nozzle is connected with trunnion, trunnion stretches in printhead cavity, initiating terminal is adjacent with feed portion, trunnion tube wall in printhead cavity is connected with radiating block, described radiating block is with metal material moulding, due to metal heat-conducting speed, below nozzle, the heat of fusing department reaches after trunnion through nozzle, can go to rapidly on radiating block, because radiator fan wind direction is towards feed portion, therefore the cold air be blown into can relatedly cool radiating block, thus the trunnion temperature be connected with radiating block is minimized, make printed material unlikely overheated in the transport process delivering to nozzle from feed portion, and the blast formed by radiator fan in cavity can be clamp-oned in trunnion cold air, further enhancing radiating effect.
The nozzle of this product is provided with forming materials cooling fan on one side, forming materials cooling fan is positioned at the side that printhead is provided with the outer wall of air channel through hole, its fan wind is to towards nozzle, and this makes the hot-air that air channel through hole flows out to be pulled away in time, not easily amasss in printhead place.
The radiator fan place of this product is provided with Air Filter, can Chalk-dust filtering, and radiating airflow is cleaned at Air Filter place before entering printhead cavity, to make in printhead cavity not easily laying dust.
The radiator fan of this product is provided with fan failure alarm device, when radiator fan produces fault, can in time alarm, and allow the timely troubleshooting of user, improve the reliability of this product further.
Printhead side wall of outer shell place is provided with fan through hole, fan through hole is located at by radiator fan, printer casing sidewall is fixed on Easy-dismounting structure, radiator fan wind direction is towards feed portion, this structure can be safeguarded radiator fan easily, can be undertaken by fan through hole after pulling down fan the simple and easy maintenance printing head cavity inner part simultaneously, decrease maintenance and disassemble work.
