2. the utility model reaches while model quality is not influenceed makes model sample faster.
3. modern print heads are using the dress of a printing head with different bores for independently possessing heater and fan
Put, convey two strip material wire rods respectively, pushed not with the tired tumbler like microscope converter by two kinds of bore printheads
Same printhead completes successively accumulation printing to print point.
4. can effectively shorten rotating path using microscope type converter, wire rod is avoided to be broken off.
Print 5. printhead is switched fast and then extensive work time and printhead volume can be reduced, improve work effect
Rate.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model；
Wherein, 1 material wire rod, 2 feeding mechanisms, 3 heaters, 4 radiator fans, 5 rotating disks, 6 first printing heads, 7 second
Printing head, 8 motors, 9 disk shafts；
Fig. 2 is elevational schematic view of the present utility model.
Embodiment
Below in conjunction with the accompanying drawings and embodiment is described in further detail to the utility model.
As shown in figure 1, the utility model includes：Feeding mechanism, heater, motor (3), gear drive, two kinds
Different bore printing nozzles.Housing is hollow cylinder type, and top closure is provided with two entrances, sets feeding mechanism；Feeding mechanism
Including gear and motor, motor driven gear, which rotates, is involved in material wire rod.Two wire rods respectively enter two conveying pipelines, through conveying
After heater heating outside pipe, flowed out respectively through two printing heads.Fan and heater equal height on housing, are used for
Heater is radiated, prevents that temperature is too high.Housing bottom is provided with rotating disk, and center of turntable is provided with disk shaft, disk shaft
By gear drive and motor connection；Two printing heads are on rotating disk.
The structure of feeding mechanism is prior art, using two identical structures, including：Gear is fed by connecting motor
To ensure to rotate, pinion rotation drives material wire rod to be involved in heater section.
Heater is prior art, and the present embodiment sets two, is controlled respectively for being used according to different shower nozzles.Fig. 1
In illustrate part corresponding to enclosure interior i.e. heater 3.Each heater includes low-temperature heater and high temperature heater (HTH), successively
Located at corresponding to printing head radiator fan, below internal part from top to bottom, that is, feeding mechanism conveying pipeline outside, uses
Heated in being heated up to molten condition to material wire rod.Heater body is resistance wire, low-temperature heater and high temperature heater (HTH)
Varying number resistance wire in parallel can be set according to temperature requirement, the resistance wire quantity of the present embodiment low-temperature heater adds for high temperature
The half of hot device resistance wire quantity, temperature are respectively 100 degrees Celsius and 200 degrees Celsius.Low-temperature heater is to ensure that in advance
Preheated material wire rod, it is ensured that high temperature melt is rapider when printing head switches, and linking is more smooth.
As shown in Fig. 2 two shower nozzles are the original different bore types of FDM printers, rotating disk bottom, internal diameter point are respectively arranged on
Other 0.4mm and 0.8mm, position are located at semicircle side, and two shower nozzle centre distance circle center distances are equal.
Motor is fixed at the opposite side semicircle of rotating disc house print shower nozzle, it is ensured that part does not extrude, for driving
The motor of dynamic axis of rotation is connected by rotating disc central interior gear drive with rotating shaft, rotating disc is rotated realization
Switch printing head.
Rotating disk is the low arc of circle, i.e. segment, and the height of the present embodiment segment is less than radius, using Microscope turret identical shape
Shape.
Motor, low-temperature heater and high temperature heater (HTH) are connected with 3D printer control chip.
When existing Slice Software analyzing three-dimensional model is filled or supported and is cut into slices, available data, analysis are utilized
Taken for support or fill part with the printhead of external model face difference bore to be printed.External model face needs essence
Close printing, inside filling support section are only used as model support because not playing outward appearance effect.So outer surface uses
0.4mm printhead is printed, and inside filling is with support using at least 0.8mm printhead come printing speed.
As shown in Figure 1, 2, new printing head by two independent feeding mechanisms respectively operate completion charging, it is necessary to
During 0.4mm diameter nozzle printings, feeding mechanism pinion rotation conveying material wire rod, two independent wire rods use a heater bag
(inside is provided with two heaters, is respectively used to the heating of two wires) heating is wrapped up in, radiator fan is located at printhead external heat
The convenient preferably radiating in device position.The printing that droplet material after heating is connected to two kinds of different bores by delivery pipe respectively is sprayed
On head.The printing of the external precision of Slice Software analysis simultaneously and internal printing speed (existing software can realize analyze data).Analysis
The structure gone out manipulates the rotating disc of printhead lower end by control chip, rotating disk internal reservation printing head position, takes hollow
Fetch bit is put, it is ensured that conveying pipeline is connected to lower end printing head position after the heating of upper end.Printing head position is taken apart from the center of circle
The position of equidistance, it is ensured that the no deviation of point of printhead after wheel disc rotates.Rotational angle collides according to not generation part
Most short rotation path, in 40 degree of position of central angle, realizing being switched fast for printing head.Need a printhead prints
When, another printing head goes to side, and the printing spray on side by the motor driven gear transmission device inside rotating disk
Mouth is closed, and the printing head positioned at print point position starts successively to accumulate to realize.
