Description
Technical field
The utility model relates to a kind of discharging control structure of 3D printer.
Background technology
3D printer is also known as three-dimensional printer, a kind of accumulation manufacturing technology, i.e. a kind of machine of RP technique, it is based on a kind of mathematical model file, use special wax material, powdery metal or plastics etc. can jointing material, manufacture three-dimensional object by the jointing material printed from level to level.At present, 3D printing technique is widely used in multiple fields such as jewelry, footwear, industrial design, building, engineering and construction (AEC), automobile, Aero-Space, dentistry and medical industries, education, GIS-Geographic Information System, civil engineering.
The output section of 3D printer is formed primarily of printing mechanism and Z axis lifting platform, and printing mechanism is responsible for material spray and is printed, and Z axis lifting platform is then for controlling the walking of printing mechanism.But, the output section of existing 3D printer also exists an obvious defect, that is: its Z axis lifting platform adopts synchronizing wheel and Timing Belt to drive the mode of two rhizoid bars to carry out transmission mostly, control printing mechanism is elevated, because Timing Belt belongs to rubber, be easy to produce tension force, two rhizoid bar motions can not get well synchronous, thus cause lifting platform step-out or stuck, have impact on the stability of lifting platform and the printing effect of printer.
In addition, the shower nozzle of existing 3D printer output section adopts heat-preservation cotton to wrap up mostly, then outside winding High temperature-resistanadhesive adhesive tape, not only outward appearance is ugly for this kind of heat preserving mode, if heat-preservation cotton parcel is imperfect, then easily cause temperature to rise slowly, make insulation occur unstable situation, cause adhesive tape to come off, thus have impact on the speed of printing.
Utility model content
The purpose of this utility model is the discharging control structure providing a kind of 3D printer, and the output section mainly solving 3D printer exists the unreasonable and problem that print speed is slow of Z axis lifting platform structural design.
To achieve these goals, the technical solution adopted in the utility model is as follows:
A kind of discharging control structure of 3D printer, comprise two Z axis lifting platforms, and to be arranged between two Z axis lifting platforms and there is the printing mechanism of shower nozzle, described Z axis lifting platform comprises bracing frame, to be arranged in this bracing frame and the first position-limited rack distributed up and down and the second position-limited rack, be arranged on the first gear between two limiting brackets, form the second gear of umbrella pinion with this first gears meshing, and be connected with this second gear, for driving the motor of this second pinion rotation; Be provided with screwed hole in described first gear, be connected with screw mandrel in this screwed hole, this screw mandrel top is fixed with Connection Block; Described printing mechanism is connected with this Connection Block; Described shower nozzle outside is also provided with the protector for being incubated it.
As preferably, described motor is stepper motor.
As preferably, the gear ratio of described first gear and the second gear is 2: 1.
Specifically, described protector comprises the heat-insulation layer being wrapped in shower nozzle outside completely, and is enclosed within the sheath of this heat-insulation layer outside completely.
Compared with prior art, the beneficial effects of the utility model are:
(1) the utility model reasonable in design, the lifting of its Z axis have employed umbrella pinion and drives the positive drive mode of screw mandrel to drive printing mechanism to move, have and move the advantage steady, transmission is effective, sync rates is high, and the utility model can also adjust the rate of climb of screw mandrel by the gear ratio designing the first gear and the second gear, thus not only ensure that the stationarity of lifting platform well, and optimize the effect of printing.
(2) setting of sheath ensure that integrality and the stability of heat-insulation layer, and improves the speed of temperature rising, thus not only ensures the normal use of shower nozzle, and effectively accelerates the speed of printing.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Wherein, the parts name that Reference numeral is corresponding is called: 1-printing mechanism, 2-shower nozzle, 3-Connection Block, 4-screw mandrel, 5-first position-limited rack, 6-first gear, 7-second gear, 8-second position-limited rack, 9-bracing frame, 10-motor, 11-heat-insulation layer, 12-sheath.
Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with accompanying drawing, the utility model is further elaborated.
As shown in Figure 1, the utility model comprises two Z axis lifting platforms, and to be arranged between two Z axis lifting platforms and there is the printing mechanism 1 of shower nozzle 2, described Z axis lifting platform comprises bracing frame 9, to be arranged in this bracing frame 9 and the first position-limited rack 5 and the second position-limited rack 8 distributed up and down, be arranged on the first gear 6 between two limiting brackets, engage with this first gear 6 and form the second gear 7 of umbrella pinion, and being connected with this second gear 7, for driving the motor 10 of this second pinion rotation; Be provided with screwed hole in described first gear 6, be connected with screw mandrel 4 in this screwed hole, this screw mandrel 4 top is fixed with Connection Block 3; Described printing mechanism 1 is connected with this Connection Block 3.Motor 12 in the present embodiment is preferably stepper motor, and the gear ratio of the first gear 6 and the second gear 7 is 2: 1, and so the number of teeth of design two gears can make motor 12 control the walking of screw mandrel 4 better, and makes its printing effect better.
