The microswitch 5 is fixed on the heat radiating tube 2 through the microswitch base 1; the polytetrafluoroethylene tube 3 penetrates through the quick joint 4 and the heat radiating tube 2 to enter the nozzle module 10; the heat radiating tube 2 is pressed into a step hole in the lower end of the fixed base 7 by the spring 8; the upper end surface of the spring 8 is pressed on the lower end surface of the effector 6; the effector 6 is linked with the fixed base 7 through a screw; the nozzle module 10 is fixed at the lower end of the heat radiating tube 2 through the locking screw 9; and the side surface heat radiating module 11 is used for a model and the nozzle to radiate heat. The invention is advantaged in that the nozzle can automatically bounce to avoid printing failure when suffering edge warping and projections in the printing process; automatic leveling is performed by using the nozzle to directly trigger the microswitch so that the compensation is accurate; and the nozzle module is convenient to maintain.
Description
Technical field
The present invention relates to a kind of 3D and print rapid shaping technique field, particularly relate to the shower nozzle of desktop type 3D printer.
Background technology
Existing Table top type 3D printer is in print procedure, when print platform is uneven or model has the situation of projection or alice, it is easy to occur printing staggered floor or shower nozzle prizes printed model and ultimately results in and print unsuccessfully；It addition, what existing printer head adopted substantially is enclosed construction, once blocking occurs in nozzle, can only all dismantle or change whole shower nozzle, repair demolition inconvenience, and spray nozzle clogging fault is one of desktop type modal fault of 3D printer；Printer with automatic flat-adjustable function is more on the market, but the collection of leveling point substantially rests on arranges around nozzle that data are acquired by special leveling contact, structure is complicated, and the position of collection point is inconsistent with the position of actual nozzle, position migration need to be carried out in the algorithm, affect leveling precision.
Summary of the invention
In view of above-mentioned condition, the present invention proposes a kind of flexible buffer shower nozzle and 3D printer, to solve above-mentioned existing shower nozzle institute produced problem.
For reaching above-mentioned purpose, the technical scheme is that and be achieved in that.
A kind of flexible buffer shower nozzle and 3D printer, including microswitch seat, radiating tube, snap joint, four fluorine tube, microswitch, effector, fixing seat, spring, lock-screw, nozzle module, radiating module.
Described flexible buffer shower nozzle and 3D printer, microswitch is fixed on radiating tube by microswitch seat, and radiating tube top is connected to snap joint for connecting four fluorine tube；Radiating tube lower end is by spring compression in the middle of the stepped hole of fixing seat, and spring upper end contacts with effector, is connected by screw is fixing between effector with fixing seat；Nozzle module is fixed in the middle of the through hole of radiating tube lower end by two lock-screws, and the radiating module being fixed on fixed seat side face has the heat sinking function to model and shower nozzle self concurrently.
Described flexible buffer shower nozzle and 3D printer, microswitch shell fragment when shower nozzle normal operation is in closure state, running at shower nozzle under barrier or leveling state, microswitch shell fragment can be triggered and flick, and after barrier elimination, microswitch shell fragment can automatically restore to closure state.
Described flexible buffer shower nozzle and 3D printer, radiating tube is hollow structure, and four fluorine tube is inserted from upper end by snap joint, and lower end contacts with nozzle module.
Described flexible buffer shower nozzle and 3D printer, spring force requires nozzle module can automatically upspring when running into barrier the height within 2mm, and obstacle disappear after can automatically restore to initial position, additionally, in shower nozzle normal print process, nozzle module occurs without and rocks and loosen.
Described flexible buffer shower nozzle and 3D printer, nozzle module is fixed on radiating tube lower end by two lock-screws, only need to unclamp two lock-screws during dismounting, and nozzle module can quickly take off.
Described flexible buffer shower nozzle and 3D printer, radiating module is arranged in fixed mount side, can simultaneously to printer model and shower nozzle self-radiating.
Beneficial effects of the present invention: by the use of the present invention, if printer shower nozzle in print procedure runs into that print platform is uneven or model has the situation of projection or alice, nozzle can automatically be upspring and be avoided printing unsuccessfully；When nozzle generation plugging fault, nozzle module can quickly be dismantled by two screws that only need to come loose, it is simple to changes and maintenance；When carrying out automatic leveling, nozzle, as the trigger point of data acquisition, simplifies structure, and leveling is more accurate.
Below in conjunction with drawings and Examples, the invention will be further described.

Specific embodiment
Below in conjunction with the drawings and specific embodiments, the invention will be further described, but not as limiting to the invention.
As it is shown in figure 1, flexible buffer shower nozzle and 3D printer, including microswitch seat 1, radiating tube 2, four fluorine tube 3, snap joint 4, microswitch 5, effector 6, fixing seat 7, spring 8, lock-screw 9, nozzle module 10, radiating module 11.Microswitch 5 is fixed on radiating tube 2 by microswitch seat 1, radiating tube 2 is terminated with snap joint 4, four fluorine tube 3 is inside snap joint 4 and radiating tube 2 until in the middle of nozzle module 10, radiating tube 2 is pressed in the stepped hole of fixing seat 7 lower end by spring 7, and spring 8 upper surface is pressed in the lower surface of effector 6；Adopt between effector 6 and fixing seat 7 and be screwed；Nozzle module 10 is fixed in the through hole of radiating tube 2 lower end by lock-screw 9；Side radiating module 11 is for printer model and shower nozzle self-radiating.
Preferably: the position of microswitch seat 1 need to ensure that microswitch 5 shell fragment under shower nozzle normal operating conditions is in closure state, in automatic leveling state or to run into print platform uneven or when printer model has projection, shower nozzle can be lifted up 2mm with inner height, and can trigger microswitch work at 0.2mm place.
Preferably: the elastic force of spring 8 need to meet the nozzle module 10 height within running into the 2mm that can automatically upspring when model has projection, and initial position can be automatically restored to after print platform injustice or model projection factor disappear, additionally, in shower nozzle normal print process, nozzle module occurs without and rocks and loosen.
In sum, by the use of the present invention, if printer shower nozzle in print procedure runs into that print platform is uneven or model has the situation of projection or alice, nozzle can automatically be upspring and be avoided printing unsuccessfully；When nozzle generation plugging fault, nozzle module can quickly be dismantled by two screws that only need to come loose, it is simple to changes and maintenance；When carrying out automatic leveling, nozzle, as the trigger point of data acquisition, simplifies structure, and leveling is more accurate.
