Description
Technical Field
The utility model relates to the technical field of 3D printers, in particular to a nozzle for accelerating consumable melting of a 3D printer.
Background
Under the condition of 3D printing technique becoming mature day by day, there has higher and higher requirement to the printing speed of 3D printer, in order to satisfy the extrusion problem of consumptive material under the high-speed condition of printing, needs to increase the flow of extruding the consumptive material.
The current 3D printer nozzle is the hollow cylinder structure that the metal was made, and it is the feed inlet of consumptive material that the diameter of going up mouthful is great, and the diameter of end opening is less the discharge gate of consumptive material. The outer wall of the nozzle is provided with threads and is used for being fixed on a heating block, a heating rod is fixed on the heating block, an electrode is attached to the heating rod and is electrified to heat, and therefore consumable materials in the nozzle are melted and extruded.
The prior art has the disadvantages that the nozzle is heated by the heating block from the outside, the melting amount of consumable materials cannot meet the requirement of high-speed printing, and the structure of the consumable materials needs to be improved.
SUMMERY OF THE UTILITY MODEL
In order to overcome the defects of the prior art, the utility model provides the nozzle for accelerating the melting of consumables of the 3D printer, and the problem that the high-speed printing requirement cannot be met due to the low consumable melting speed of the nozzle is effectively solved.
The technical scheme for solving the technical problem is as follows: the utility model provides a nozzle that is used for 3D printer to melt consumptive material with higher speed, is including feed portion and nozzle portion that link together, and feed portion and the inside feed passage that link up of nozzle portion are equipped with, feed passage include with feed portion complex cylindricality chamber and with nozzle portion complex nozzle chamber, the cylindricality chamber is close to the middle part of nozzle chamber one end and is equipped with the hot plate.
Preferably, the connection part of the feeding part and the nozzle part is provided with a ring groove.
Preferably, the nozzle chamber comprises a conical chamber connected with the cylindrical chamber and a linear chamber penetrating through the end part of the nozzle part.
Preferably, the taper angle of the tapered cavity is 60 °.
Preferably, the length of the heating plate is half of the length of the cylindrical cavity.
The utility model has simple and ingenious structure, and can heat the consumables in the nozzle through the heating sheet, accelerate the consumable melting speed and improve the consumable melting efficiency, thereby meeting the requirement of high-speed printing.

FIG. 3 is a schematic cross-sectional view A-A of FIG. 2 of the present invention.
Detailed Description
The following describes embodiments of the present invention in further detail with reference to the accompanying drawings.
As can be known from figures 1 to 3, a nozzle for accelerated melting of consumables of a 3D printer comprises a feeding portion 1 and a nozzle portion 2 which are connected together, wherein an annular groove 7 is arranged at the joint of the feeding portion 1 and the nozzle portion 2, a feeding channel 3 is arranged inside the feeding portion 1 and the nozzle portion 2 in a penetrating mode, the feeding channel 3 comprises a cylindrical cavity 4 matched with the feeding portion 1 and a nozzle cavity 5 matched with the nozzle portion 2, a heating plate 6 is arranged in the middle of one end, close to the nozzle cavity 5, of the cylindrical cavity 4, and the length of the heating plate 6 is half of that of the cylindrical cavity 4.
When the utility model is used, the water-saving agent is added,
at nozzle external fixation heating piece, annular 7 and heating piece edge joint, the consumptive material enters into feedstock channel 3 from 1 one end of feeding portion in, be divided into in the cylindrical cavity 4 and do not have hot plate 6 part and have hot plate 6 part, the consumptive material at no hot plate 6 part is earlier through preheating melting of heating piece, then it has hot plate 6 part time and is divided into two parts by hot plate 6 to get into, hot plate 6 is made for the metal, can heat conduction, heat the consumptive material from the consumptive material is inside, make the consumptive material melt with higher speed, the demand of melting the consumptive material with higher speed when satisfying high-speed printing.
The hot plate 6 separates the consumptive material from the centre, and the consumptive material has increased the area of contact of consumptive material with the heat source with the 6 contacts of hot plate to realize inside and outside simultaneously to the purpose of consumptive material heating, make the consumptive material more abundant melting faster, satisfy the demand of high-speed printing.
The nozzle cavity 5 comprises a conical cavity 8 connected with the cylindrical cavity 4 and a linear cavity 9 penetrating through the end part of the nozzle part 2, the taper angle of the conical cavity 8 is 60 degrees, consumables are extruded to the linear cavity 9 from the conical cavity 8, the taper angle of the conical cavity 8 is set to be 60 degrees, molten consumables are more uniform and smooth when passing through the nozzle, and the stability and the reliability of the printing operation of the 3D printer are guaranteed.
Compared with the prior art, the utility model has the following beneficial effects: through setting up the hot plate, the area of contact of increase consumptive material and heat source accelerates consumptive material melting speed, satisfies the demand of high-speed printing.
