Detailed description of the invention
For making the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with detailed description of the invention also with reference to accompanying drawing, the utility model is further described.Should be appreciated that, these describe just exemplary, and do not really want to limit scope of the present utility model.In addition, in the following description, the description to known features and technology is eliminated, to avoid unnecessarily obscuring concept of the present invention.
Fig. 2 shows the drip-proof shower nozzle structural representation of the 3D printer according to the utility model first embodiment; Fig. 3 shows nozzle arrangements schematic diagram in Fig. 2;
As shown in Figures 2 and 3, a kind of drip-proof shower nozzle of 3D printer, comprise nozzle 1, the upper end of described nozzle 1 centre bore is thick portion 11, lower end is thin portion 12, described thin portion 12 is provided with to downward-extension and extends thin portion 13, described nozzle 1 extends the aperture in thin portion 13 between 0.2mm to 0.5mm, and the best can select 0.4mm.
Contiguous block 2 is positioned at the top of described nozzle 1, heat block 3 coordinates fixing with the bottom of described nozzle 1 and described contiguous block 2 respectively, in the present embodiment, described nozzle 1 and contiguous block 2 are provided with external screw thread, and described heat block 3 is provided with internal thread and coordinates fixing with the external screw thread of described nozzle 1 and described contiguous block 2.
Described heat block 3 is provided with circular hole, heating rod 31 is located in described circular hole, in order to heat the printed material in described nozzle 1, in the present embodiment, described nozzle adopts the good copper of heat-conducting effect to be made, ensure that the heat of described heating rod 31 can pass to printed material rapidly, thus be conducive to the printed material heated fast in nozzle 1.And the aluminium that described heat block 3 adopts heat-conducting effect good is made, while reducing costs, also ensure that heat can pass to nozzle rapidly.
Radiating block 4 is positioned at the top of described heat block 3 and coordinates with the top of described contiguous block 2 fixing, and in the present embodiment, described radiating block 4 is provided with internal thread and coordinates with the external screw thread of described contiguous block 2 fixing.The top that described radiating block 4 is positioned at described heat block 3 leaves heat, described radiating block 4 also adopts the good aluminium of heat-conducting effect to be made, described radiating block 4 makes many dentation fin, increasing heat radiation area as much as possible simultaneously, ensure that the heat on fin can distribute rapidly.On radiating block, secure a radiator fan simultaneously, substantially increase the speed that heat distributes.
Be provided with neck 21 between the upper and lower of described contiguous block 2, the stainless steel that described contiguous block 2 adopts heat-conducting effect very poor is made.So both added the intensity of material, and ensured can not rupture at described neck 21, additionally reduce heat transmission upward, ensure that the printed material inside described contiguous block 2 top can not melt because of overheated.With the neck 21 of described contiguous block 2 for boundary, being the hot junction of shower nozzle below, is the cold junction of shower nozzle above.Still keep normal state at the printed material of cold junction, do not start to melt.The printed material entering hot junction has been heated to the temperature needed, and normally melts.The printed material volume ratio of melting decreases many before improving, weight is also just light a lot.Simultaneously because the thin portion 13 of prolongation of the spray nozzle front end extended in turn increases frictional force, just ensure that weeping can not produce.
The thin portion 13 of described prolongation increases frictional force, and the frictional force of wherein increase mentioned here is mainly from two aspects: the resistance of the stickiness generation of the capillarity that surface tension produces and liquid.
Wherein, surface tension is a kind of physical effect, and it makes the total surface of liquid be attempt to obtain minimum, smooth area, just look like it is that the flexible film of one deck is the same.Its reason is the total surface of liquid is the state attempting to reach minimum energy.Tension force between the material of broadly all two kinds of different states of matters on interface is called as surface tension.Surface tension is an internal force, even if surface tension also exists in a balanced condition.
Capillarity (also known as capillarity) refers to that liquid is inside thin tube-like object, due to cohesive force and adhesive force difference, overcome centrifugal force and the phenomenon risen.Capillarity is the attraction of liquid surface to the surface of solids.
In capillarity, liquid lifting height is:
In formula: γ is surface tension; θ is contact angle; ρ is fluid density; G is acceleration of gravity;
R is tubule radius.
As θ >90 °, expression meniscus is convex surface, simultaneously h<0, and express liquid declines in capillary.
The surface tension of printed material is at 30 to 40mN/m.Density and water are similar, at 1g/cm^3.Gravity acceleration g is 9.8m/s^2.Tubule radius is 0.4mm.Contact angle needs to carry out measuring according to different materials, and scope is 30 degree to 60 degree, supposes that contact angle is 45 degree, is highly 12.6mm according to parameter calculates above.
Liquid or gas are when flowing, and the character rubbed in its intermolecular generation, is called the stickiness of liquid, and the size of stickiness represents by viscosity, are used to characterize the relevant resistance factor of liquid property.As, be 1m by two pieces of areas
2plate be dipped in liquid, two plate distances are 1 meter, if add the tangential force of 1N on a certain block of plate, make the relative speed between two plates be 1m/s, then the viscosity of this liquid is 1Pas.
Fig. 4 shows parallel flat experiment schematic diagram in the first embodiment.
As can be seen from Figure 4, near the plate do not moved, the speed of liquid motion can reduce rapidly along with the reduction of distance, also just means that the resistance that stickiness causes rises rapidly.Aperture due to spray nozzle front end is 0.4mm, and the resistance that therefore stickiness causes will be very large.
The technical scheme of this first embodiment, by the thin of prolonging nozzle front end, increasing friction force, ensure that weeping can not produce, but the resistance that simultaneously also can increase when extruding printed material, require that wire squeeze motor needs enough strength and promotes printed material advance.If the long resistance that just may cause of the thin of spray nozzle front end is excessive, wire squeeze motor does not have enough strength to promote printed material advance.Therefore need to be optimized the length of spray nozzle front end thin, existing enough frictional force ensures to produce weeping, do not have again too large resistance that motor pushing printed material can not be hindered to advance, the more optimal scheme of needs like this, on the basis ensureing nozzle not water clock, also easy to use.
