Abstract
The utility model relates to a kind of PEEK shower nozzle for 3D printer, comprises nozzle body, the front connector at two ends, rear connector, shower nozzle and be positioned at the radiating groove of shower nozzle periphery, and nozzle body is the cylindrical-shaped structure of the internal run-through of PEEK material; Front connector is for connecting the nozzle of 3D printer; Radiating groove, for organize scalloped recess, often organizes radiating groove spaced apart on shower nozzle outer wall more; Between every two groups of radiating grooves, interval offers louvre.The utility model offers louvre, increases heat radiation contact area further, increases radiating effect, each shower nozzle designs the radiating effect that 20 radiating grooves ensure shower nozzle further in addition, guarantees to print raw material not melting in advance; In addition shower nozzle inwall is designed to the structure of certain tapering, prevent nozzle temperature too high be delivered on shower nozzle, make its expanded by heating, melt will upwards recoil but have certain tapering can stop melt adverse current, solves melt Conveying problem.
Description
Technical field
The utility model relates to a kind of PEEK shower nozzle for 3D printer.
Background technology
3D printer, also known as three-dimensional printer, is a kind of accumulation manufacturing technology, by the bonding from level to level of programme-control fusible plastic, cooling and the three-dimensional body printed, present stage three-dimensional printer be used to the perparation of specimen.Need to use in proofing process the good and effect of heat insulation of temperature tolerance in might as well shower nozzle connect nozzle, can prevent the transmission of high temperature nozzle heat from making material do sth. in advance melting like this and cause printing effect bad.Conventional nozzle arrangements is direct-connected, machined combined type, but all there is the bad or easy shortcoming that blocking occurs of heat radiation, and simultaneously because nozzle is taper, the melt of melting easily recoils to shower nozzle from nozzle.
The method solving the problem of nozzle heat radiation in prior art has utility model patent 3D printer extrusion device, application number is 2014200920998, disclose a kind of 3D printer extrusion device, the nozzle comprising pedestal and be fixed on pedestal and shower nozzle, wherein base is cylindric, and its side circumferentially has the groove of many heat radiations.But this patent base is not circumferentially opened reeded position and still be there is heat dissipation problem owing to can not fully contact with air.
Utility model content
The purpose of this utility model is: solve the problem that the radiating effect of 3D printer head in prior art is not good, and during the further 3D of solution printer prints, melt is easily from the problem that nozzle recoils to shower nozzle.
Realizing scheme of the present utility model is: a kind of PEEK shower nozzle for 3D printer, comprise nozzle body, the front connector at two ends, rear connector, shower nozzle inwall and be positioned at the radiating groove of shower nozzle periphery, described nozzle body is the cylindrical-shaped structure of the internal run-through of PEEK material; Described front connector is for connecting the nozzle of 3D printer; Described radiating groove, for organize scalloped recess, often organizes radiating groove spaced apart on shower nozzle outer wall more; Between every two groups of radiating grooves, interval offers louvre, increase the area of ingress of air, strengthen radiating effect.
The above-mentioned PEEK shower nozzle for 3D printer, described louvre can offered close to shower nozzle inwall part separately, also can not only offer close to shower nozzle inwall part but also away from position offer, now each interval has 2 louvres, air contact surfaces is long-pending more, and heat transfer effect is better.
The above-mentioned PEEK shower nozzle for 3D printer, described radiating groove is 4 groups, is uniformly distributed on the outer wall of nozzle body, and often organizing quantity is 5.
The above-mentioned PEEK shower nozzle for 3D printer, its quantity of the quantity of described louvre can be between every 2 radiating grooves 1 totally 10, or more, such as each offering on part interval offers two louvres arranged side by side.
The above-mentioned PEEK shower nozzle for 3D printer, described shower nozzle inwall is two-stage structure, and leading portion is namely close with front connector to be located as truncated cone-shaped, and back segment is cylindrical.
The utility model has positive effect: louvre is offered at (1) position that the utility model is not offering radiating groove, further increase heat radiation contact area, further increase radiating effect, in addition each shower nozzle designs the radiating effect that 20 radiating grooves ensure shower nozzle further, guarantee to print raw material not melting in advance; (2) shower nozzle inwall is designed to the structure of certain tapering, prevent nozzle temperature too high be delivered on shower nozzle, make its expanded by heating, melt will upwards recoil but owing to there being certain tapering can stop melt adverse current, solve melt Conveying problem.
Accompanying drawing explanation
In order to make content of the present utility model more easily be clearly understood, below according to specific embodiment also by reference to the accompanying drawings, the utility model is described in further detail, wherein
Fig. 1 is structural scheme of mechanism front view of the present utility model; Fig. 2 is the AA face cut away view of Fig. 1; Fig. 3 is the BB face cut away view of Fig. 2, and Fig. 4 is the structural representation of the utility model embodiment 2.
Wherein, connector before 1 nozzle body, 2, connector, 4 shower nozzle inwalls, 5 radiating grooves after 3,6 louvres.
