Abstract
The utility model discloses a 3D print head structure, including spray head shell, the fixed spacing ring that is equipped with of feed end in the spray head shell, the interior disc of spacing ring is the conical surface, and the interior disc of spacing ring is equipped with the sealing washer rather than cone combined with, is equipped with the spring between the inlet end surface in sealing washer and the spray head shell, spray head shell installs the zone of heating, install heating wire heating collar, infrared heater in the zone of heating respectively, just the heating wire heating collar sets up with the infrared heater interval, be equipped with the perforated plate in the spray head shell, be covered with the through -hole on the perforated plate. This 3D print head structure can improve product quality.
Description
Technical field
The utility model relates to 3D printer technology field, in particular to a kind of 3D printer head structure.
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 large-scale 3D printer had now produces long term wear sealing ring when silk material enters, and causes air to enter in shower nozzle, makes the product quality produced bad.Bad owing to sealing in addition, the melting material in shower nozzle can be made to overflow shower nozzle from silk material inlet port, occur waste.
Utility model content
The purpose of this utility model is to provide a kind of 3D printer head structure, to solve the deficiencies in the prior art.
For realizing the utility model object, the technical scheme of employing is:
A kind of 3D printer head structure, comprise nozzle housing, it is characterized in that, feed end in described nozzle housing is fixed with spacing ring, the inner headed face of spacing ring is the conical surface, the inner headed face of spacing ring is provided with the sealing ring with its cone match, is provided with spring between the inlet end face in sealing ring and nozzle housing; Described nozzle housing is provided with zone of heating, is separately installed with electric-heating-wire-heating circle, infrared heater in described zone of heating, and described electric-heating-wire-heating circle and infrared heater interval are arranged; Be provided with porous plate in described nozzle housing, porous plate is covered with through hole.
The beneficial effects of the utility model are, promote sealing ring by spring, spacing ring and sealing ring cone match, thus make sealing ring compress silk material, make sealing ring when Long-Time Service weares and teares, realize automatic compensation sealing, thus avoid air to enter in shower nozzle, cause product quality bad.Electric-heating-wire-heating circle and infrared heater provide enough heat energy with the use of giving in shower nozzle, both with the use of avoiding wherein side's heat spent and reduce heat insulation effect, and the setting of infrared heater can precise control of temperature.By porous plate, melting material is evenly dredged, realize evenly extruding, improve the quality of products.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of 3D printer head structure that the utility model provides.
Detailed description of the invention
Also by reference to the accompanying drawings the utility model is described in further detail below by specific embodiment.
A kind of 3D printer head structure that the utility model provides that Fig. 1 is shown, comprising: nozzle housing 1, electric-heating-wire-heating circle 2, infrared heater 6, sealing ring 3, spacing ring 4, porous plate 8 and spring 5.Feed end in described nozzle housing 1 is fixed with spacing ring 4, the inner headed face of spacing ring 4 is the conical surface, the inner headed face of spacing ring 4 is provided with the sealing ring 3 with its cone match, spring 5 is provided with between the inlet end face of sealing ring 3 and nozzle housing 1, spring 5 one end is connected with sealing ring 3, and the other end is connected with the inlet end face in nozzle housing 1; Described nozzle housing 1 is provided with zone of heating, is separately installed with electric-heating-wire-heating circle 2, infrared heater 6 in described zone of heating, and described electric-heating-wire-heating circle 2 and infrared heater 6 interval are arranged; Be provided with porous plate 8 in described nozzle housing 1, porous plate 8 is covered with through hole.
Promote sealing ring 3 by spring 5, spacing ring 4 and sealing ring 3 cone match, thus make sealing ring 3 compress silk material 7, make sealing ring 3 when Long-Time Service weares and teares, realize automatic compensation sealing, thus avoid air to enter in shower nozzle, cause product quality bad.Electric-heating-wire-heating circle 2 and infrared heater 6 provide enough heat energy with the use of giving in shower nozzle, both with the use of avoiding wherein side's heat spent and reduce heat insulation effect, and the setting of infrared heater 6 can precise control of temperature.Evenly dredged by porous plate 8 pairs of melting materials, realize evenly extruding, improve the quality of products.
The foregoing is only preferred embodiment of the present utility model, be not limited to the utility model, for a person skilled in the art, the utility model can have various modifications and variations.All within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
