Description
Technical field
The utility model relates to FDM technique 3D printer field, relates in particular to a kind of 3D printer with sprinkler height automatic station-keeping system.
Background technology
Along with the market demand and scientific and technological progress widely, 3D printer is favored by family, medical treatment, industry etc. gradually.And FDM is the abbreviation that melt extruded is piled up moulding, at present, 3D printer based on FDM technique is generally promoted in countries in the world, the material that 3D printer based on FDM technique uses has PLA, ABS etc., its operation principle is that the material that is pushed to shower nozzle the inside according to motor can melt under the effect of high temp. jetting nozzle, the material of thawing is extruded to rapid coagulation forming under the material of high temperature environment around from shower nozzle simultaneously.
At present, existing is all the position that needs manual adjustments shower nozzle based on FDM technique 3D printer, and in the time of start-print, the height of shower nozzle and base plate need to keep the distance of 0.1mm, the thickness of about a piece of paper, the object that guarantee printer prints has good effect.Just because of this, regulate the height of shower nozzle not only to lose time, and it is very loaded down with trivial details to operate, easily because of maloperation, causes shower nozzle and base plate to bump against, make shower nozzle obstruction, damage or cause the object and the base plate bonding that print insecure.
Summary of the invention
The purpose of this utility model is the defect that overcomes prior art, proposes a kind of 3D printer head that can realize FDM technique system of location automatically, and the sprinkler height that is intended to solve existing printer can not pinpoint problem.
The technical solution of the utility model is as follows:
With the 3D printer of sprinkler height automatic station-keeping system, comprise ejecting device, guide rail, height-regulating device, bottom plate apparatus, main control chip and other printer necessary device; Described ejecting device comprises heat block, wire squeeze motor and shower nozzle; Described height-regulating device comprises lead screw motor and screw mandrel, and described guide rail bracket is located on screw mandrel, and ejecting device is arranged on guide rail; Described bottom plate apparatus comprises base plate, spring, screw, pressure sensor and base, and base plate is fixed by screws on base, is arranged with spring on screw, and pressure sensor is arranged on the below of base plate; Described wire squeeze motor, lead screw motor, pressure sensor are all connected with main control chip.
Described bottom plate apparatus also comprises motor, and motor is connected with main control chip for controlling base movement in the horizontal direction.
The periphery of described printer is also provided with fixed frame, and described lead screw motor is symmetricly set on the both sides of bottom plate apparatus, and screw mandrel is arranged in lead screw motor.
Described base plate top is also provided with movably plastic plate.
Described pressure sensor is pasted on stressed force sensitive flexible member and is formed by foil gauge.
Described shower nozzle is provided with becket, with shower nozzle be an integral body.
Beneficial effect: printer provided by the utility model, can realize sprinkler height is located accurately, the signal data recording according to sensor, whether the height of confirming shower nozzle meets the demands, when highly not meeting the demands, can re-start automatic location and regulate, or carry out manual adjusting, can effectively guarantee the distance between shower nozzle and bottom plate apparatus, prevent that to print bonding insecure or sweep the situations such as medium.In addition, add becket on shower nozzle, the injury to shower nozzle in the time of effectively reducing shower nozzle and clash bottom plate apparatus, has played the effect of good protection shower nozzle.
Accompanying drawing explanation
Fig. 1 is local front-view schematic diagram of the present utility model.
Fig. 2 is whole front-view schematic diagram of the present utility model.
Fig. 3 is the front-view schematic diagram of shower nozzle in the utility model.
In figure, 1-firm banking, 2-screw mandrel, 3-lead screw motor, the peripheral fixing framework of 4-, 5-guide rail, 6-heat block, 7-shower nozzle, 8-is plastic plate movably, 9-base plate, 10-spring, 11-long spiro nail, 12-becket, 13-pressure sensor.
The specific embodiment
In order more clearly to describe the utility model, below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Figure 2, printer described in the utility model comprises firm banking 1, screw mandrel 2, and lead screw motor 3, peripheral fixing framework 4, guide rail 5, heat block 6, shower nozzle 7, movably plastic plate 8, base plate 9, spring 10, long spiro nail 11, pressure sensor 13.Peripheral fixing framework 4 and firm banking 1 can guarantee that printer has good stable state in normal work.
Wire squeeze motor, heat block 6 links together with shower nozzle 7, by their motions on guide rail 5 of Electric Machine Control.Lead screw motor 3 is symmetricly set on the both sides of firm banking 1, and screw mandrel 2 symmetries are arranged on above lead screw motor 3, can guarantee all states in level of guide rail 5 and shower nozzle 7.Base plate 9 is fixed together by long spiro nail 11, prevents from coming off.The outer spring 10 that is arranged with of long spiro nail 11, plays the effect of buffering.Movably plastic plate 8 use clips are fixed on the top of base plate 9, make movably plastic plate 8 to dismantle easily and to install, and for getting printed model, bring great convenience.
Pressure sensor 13 is arranged on the below of base plate 9 and is connected with main control chip.Base plate 9 and pressure sensor 13 stick together, but unable effect mutually, can be mutually movable.Pressure sensor 13 is that foil gauge is pasted on stressed force sensitive flexible member, and flexible member is arranged on the below of base plate, when base plate 9 is stressed, flexible member also can stressed generation deformation, foil gauge produces corresponding strain, is converted into the variation of resistance, and then is converted into measurable signal.Base plate 9, spring 10, long spiro nail 11, pressure sensor 13 are done as a whole, can under the effect of stepper motor, move forward and backward.
At the sheathed becket 12 in the periphery of shower nozzle 7, can effectively reduce the shower nozzle injury of base plate to shower nozzle that clash, played the effect of good protection shower nozzle 7.
Principle of the present utility model: at Fig. 1, in Fig. 2, when shower nozzle 7 carries out shower nozzle while surveying, if when main control chip can not receive the signal from pressure sensor 13, shower nozzle 7 moves downward always always.When removable plastic plate 8 is subject to the pressure of shower nozzle 7, base plate 9 and pressure sensor 13 also can be subject to equal pressure.Main control chip is received after the signal of pressure sensor 13, drive lead screw motor 3 to reverse direction operation, and record the height H of shower nozzle 7 this moment, thereby host computer obtains the height H set=H-0.1 of the self-align setting of another one, setting height using Hset as printer head prints, thereby can play the self-align effect of sprinkler height.
To those of ordinary skills, still can modify according to recorded technical scheme, or part technical characterictic is wherein equal to replacement, the modification of all technology and replace and all should belong to the protection domain of the affiliated claim of the utility model.
