It is slow.3D printing concrete technology is to combine the concrete material after improvement match ratio with 3D printing technique and generate emerging skill
Art.3D printing technique is one of the developing direction in building industrialization future, but still in its infancy, has many problems to need to be solved
Certainly.
The present invention is a kind of rotation concrete printer head of interchangeable nozzles.Studies have shown that the matter of 3D printing concrete
It measures closely bound up with nozzle form.Rectangular print spray head can make discharging more uniform on perpendicular to direction of travel, greatly improve
Print quality, and different models should match the nozzle of different sizes, shape；The print quality of rectangular nozzle is higher than round nozzle
Print quality, but rectangular nozzle require spray head rotated with direction of feed.The present invention makes concrete printer have better adaptation
Property, and improve printing precision and printing intensity.
Summary of the invention
Goal of the invention: in view of the foregoing drawbacks, the present invention provides a kind of raising printing effect, improves the interchangeable spray of printing effect
The rotation concrete printer head of mouth.
Technical solution: the present invention proposes a kind of rotation concrete printer head of interchangeable nozzles, including sliding rail and spray head
Body, is connected between the sliding rail and sprayer body by head cartridge, and the sprayer body is internally provided with agitating device, the spray head
It is provided with feeding device above body, the sprayer body end is provided with nozzle, is provided with gear wheel on the sprayer body outer wall, institute
It states and is provided with rotating electric machine on head cartridge, pinion gear is provided on the rotating electric machine, the pinion gear is engaged with gear wheel.
Further, the agitating device is set by stirring motor, shaft coupling and stirring bar construction, the stirring motor fixation
It sets on the slide rail, is provided with stirring rod below the stirring motor, connected between the stirring rod and stirring motor by shaft coupling
It connects.
Further, it is connected between the sprayer body and head cartridge by thrust bearing.
Further, it is connected through a screw thread between the sprayer body and nozzle.
Further, helical blade is provided with below the stirring rod.
Further, the feed inlet is arranged on the outside of blender.
Further, the top of sprayer body is arranged in the gear wheel.
The present invention by adopting the above technical scheme, has the advantages that
To be threadedly coupled between nozzle of the present invention and sprayer body, and nozzle remove rear stirring rod can be by shaft coupling
It removes, easy to disassemble, installation, replacement and cleaning.
Sprayer body in the present invention can be rotated with nozzle with the change of direction of feed, remain that rectangular nozzle is long
Side is vertical with direction of feed, improves print quality, enriches printing effect.
Detailed description of the invention
Fig. 1 is the structural diagram of the present invention schemes；
Fig. 2 is internal view of the invention.
Specific embodiment
Combined with specific embodiments below, the present invention is furture elucidated, it should be understood that these embodiments are merely to illustrate the present invention
Rather than limit the scope of the invention, after the present invention has been read, those skilled in the art are to various equivalences of the invention
The modification of form falls within the application range as defined in the appended claims.
As shown in Figs. 1-2: the present invention proposes a kind of rotation concrete printer head of interchangeable nozzles, by sliding rail 1, spray head
Bracket 2, rotating electric machine 3, nozzle 4, thrust bearing 5, sprayer body 6, stirring rod 7, shaft coupling 8, stirring motor 9 and 10 groups of feed inlet
At.Sliding rail 1 is used to connect square rail and head cartridge 2 in printer body, the movement in a direction is realized, with printer body
Cooperative movement；It is the long stick of optical axis that stirring rod 7, which has helical blade, top for a lower part, and upper end and stirring motor 9 pass through shaft coupling
Device 8 connects, and the rotation of stirring motor 9 drives stirring rod 7 to stir and squeezes out concrete, and stirring rod 7 can be when nozzle 4 be unloaded from shaft coupling
It removes and is cleaned on device 8；Rotating electric machine 3 drives sprayer body 6 to rotate with nozzle 4 with the change for feeding path direction, rotates
The kind of drive between motor 3 and sprayer body 6 is that gear engages；Sprayer body 6 is cylinder, and external screw thread is arranged at lower part, and top is with teeth
The gear teeth can accommodate the concrete printed material continuously supplied outside fraction, be connected between head cartridge 2 by thrust bearing 5
It connects.Rotating electric machine 3 rotates, and by the transmission gear between sprayer body 6, sprayer body 6 can be driven to revolve on head cartridge 2
Turn；Internal screw thread is arranged at 4 top of nozzle, by being threadedly coupled between sprayer body 6, facilitates and replaces different size according to different printing demands
Nozzle 4, and nozzle 4 remove it is rear easy to clean.
The present invention should select corresponding nozzle 4 before use.If selecting round nozzle 4, rotating electric machine 3 does not start；If
Rectangular nozzle 4 is selected, the direction of rectangular nozzle 4 is resetted when system boot, rotating electric machine 3 and remaining motor coordination work, and make square
The long side of shape nozzle 4 keeps vertical with direction of feed.
It must be dismantled and be cleaned after the completion of the every subjob of nozzle 4 of concrete 3D printer, it can also in print procedure
The nozzle 4 of different size can be needed replacing, Gu nozzle 4 must easy to disassemble, installation and cleaning.Nozzle 4 and printing in the present invention
Body is connected, easy to disassemble with sprayer body 6 by being threadedly coupled, and screws reliable.Three kinds of nozzles 4 are designed, adaptation difference is beaten respectively
Print scene.(size is respectively as follows: a- diameter 20mm；b-10mm x 20mm；c-10mm x 30mm)
Three kinds of 4 types of nozzle that this patent refers to only are suitble to the scheme of part print scene.It is all to be referred to using this patent
Replaceable thought design other 4 schemes of nozzle, within the protection domain of this patent..
Sprayer body 6 of the present invention is the quick-replaceable and sprayer body 6 of nozzle 4 in the maximum difference of other sprayer bodies 6
Controllable rotating, have relatively big difference with other 3D concrete printers.
The rotation of sprayer body 6, which is engaged by rotating electric machine 3 by gear, drives sprayer body 6 to realize.Wheel is fixed on sprayer body 6
Tooth engages completion transmission with the gear being connected on 3 motor shaft of rotating electric machine.Sprayer body 6 and nozzle 4, sprayer body 6 and head cartridge
Thrust bearing 5 is all passed through in connection between 2, and sprayer body 6 is freely rotated in the case where sprayer body 6 is fixed together with nozzle 4.
This invention allows nozzle 4 according to the needs of printing path and printing effect, in real time covert rotation, the length of rectangular nozzle 4
Side can remain vertical with direction of feed, to improve print quality, enrich printing effect.
