Shower nozzle 3 forms primarily of spray nozzle part 31 and guide pin bushing portion 32, and the two is connected by tandem combines.The protruded length of spray nozzle part 31 should be greater than the thickness of heating rod 4, and spray nozzle part 31 is provided with axial through hole-material spraying hole 35, and the diameter of this material spraying hole 35 directly determines printing precision in print job and speed.The outer wall in guide pin bushing portion 32 offers multiple louvre 33, guide pin bushing portion 32 is provided with axial through hole-feedhole 34, and this feedhole 34 should be connected and communicates with material spraying hole 35 order.
Shower nozzle 3 of the present utility model is separate three, and their difference is only the aperture of feedhole 34 and the aperture in the aperture of material spraying hole 35, especially material spraying hole 35.The material spraying hole aperture of first shower nozzle is 1.75mm, and the material spraying hole aperture of second shower nozzle is 3.0mm, and the material spraying hole aperture of the 3rd shower nozzle is 5.0mm.
Pay-off (non-the utility model contributes to prior art, not shown) is arranged on printer support.Pay-off is primarily of around compositions such as material roller, feeding motor (stepper motor), feeding pair rollers.Material (thread) is printed for being wound around around material roller.The output shaft of feeding motor is connected with reducing gear, and the output shaft of reducing gear is connected with feeding pair roller.Under the effect of feeding motor, the drive roll of feeding pair roller coordinates with driven voller and rotates, thus with frictional force effect, the printing material on material roller is flowed to corresponding shower nozzle.
Because the utility model adopts three separate shower nozzles 3, in order to the difficulty that simplifies the operation, pay-off of the present utility model also adopts separate three, and they form three corresponding between two covers with three shower nozzles 3.
Head body frame 1 is for assembling three shower nozzles 3 and heating rod 4.Head body frame 1 primarily of interior sky, the fixed mount 11 of hemisphere shape and adjustable shelf 12 form.
The edge part internal diameter of fixed mount 11 is slightly larger than the edge part external diameter of (difference should within the scope of 5 millimeters) adjustable shelf 12.Fixed mount 11 offers electrical wire channel holes 111 and the material perforation 112 of through hole shape, and three cover detent mechanisms 13 are provided with on the edge part inwall of fixed mount 11, concrete, often overlap detent mechanism 13 primarily of the shrinkage pool be opened on fixed mount 11 edge part inwall, be assemblied in holding out against spring 132, be assemblied in shrinkage pool and be in the spheroid 131 holding out against spring 132 outer end place in shrinkage pool and form.Three cover detent mechanisms 13 on fixed mount 11 are on the same circular path of fixed mount 11 edge part inwall, and three cover detent mechanisms 13 on fixed mount 13, present position should be corresponding with the installation site of three shower nozzles 3 on following adjustable shelf 12, namely three cover detent mechanisms 13 to be arranged on the edge part inwall of fixed mount 11 (angle between the axis extended line of adjacent two cover detent mechanisms 13 is 120 °) in the mode of ring Zhou Junbu.
Adjustable shelf 12 is for installing three shower nozzles 3 and heating rod 4, concrete, three shower nozzles 3 are arranged on (angle between the axis extended line of adjacent shower nozzle 3 is 120 °) on adjustable shelf 12 in the mode of ring Zhou Junbu, and the spray nozzle part 31 of each shower nozzle 3 exposes from the outer wall surface projection of adjustable shelf 12, guide pin bushing portion 32 to be in adjustable shelf 12 in sky.Heating rod 4 is resistance wire type heater, and it is primarily of heating plate and shank composition; The heating plate of heating rod 4 is dome shape structure, and its inner surface contour is matched with the outer surface profile of adjustable shelf 12; The shank plug-in mounting of heating rod 4 is fixed on adjustable shelf 12, and the heating wires 41 of heating rod 4 is drawn from the electrical wire channel holes 111 of fixed mount 11; The heating plate of this heating rod 4 offers the perforation of three shower nozzles 3 on corresponding adjustable shelf 12, the installation of heating rod 4 on adjustable shelf 12 is fixed, three perforation on heating rod 4 heating plate are made to be sleeved on the spray nozzle part 31 of corresponding shower nozzle 3, for heating the spray nozzle part 31 of shower nozzle 3.
Adjustable shelf 12 is inserted in fixed mount 11.The edge part outer wall of adjustable shelf 12 offers with ring week equal mode for cloth the detent of corresponding three shower nozzle 3 positions, these three detents are in (angle between the axis extended line of adjacent positioned groove is 120 °) on the same circular path of adjustable shelf 12 edge part outer wall, and this also just makes three detents on adjustable shelf 12 edge part outer wall correspond to three detent mechanisms 13 on fixed mount 11 edge part inwall.Fitted together by the cooperation of detent and detent mechanism 13 between adjustable shelf 12 and fixed mount 11, meanwhile, the relative displacement between adjustable shelf 12 and fixed mount 11 also relies on detent and the detent mechanism 13 of corresponding matching.
In order to ensure the reliability of relative displacement between adjustable shelf 12 and fixed mount 11; adjustable shelf 12 edge part outer wall offers the gathering sill in one ring week; this gathering sill is the circular path of three detents on adjustable shelf 12; that is; three detents on adjustable shelf 12 are in the gathering sill in ring week, but the degree of depth of gathering sill should be shallower than the degree of depth (normally the detent degree of depth 1/2) of detent.The depth capacity of aforementioned detent is 1/2 ~ 3/4 of spheroid 131 diameter of detent mechanism 13.
Above-mentioned concrete technical scheme, only in order to the utility model to be described, is not intended to limit.Although be described in detail the utility model with reference to above-mentioned concrete technical scheme, those of ordinary skill in the art has been to be understood that: it still can be modified to above-mentioned concrete technical scheme, or carries out equivalent replacement to wherein portion of techniques feature; And these amendments or replacement, do not make the essence of appropriate technical solution depart from the spirit and scope of the technical solution of the utility model.
