Description

Technical Field

[0001] The utility model relates to the technical field of printing, in particular to a 3D printer material outlet head capable of accurately controlling the material output volume. Background Technique

[0002] Printing generally refers to outputting visible data such as text or pictures in a computer or other electronic devices onto recording materials such as paper through a printer;

[0003] Ordinary printers used in daily life can print flat objects designed by a computer. The so-called 3D printer has basically the same working principle as an ordinary printer, except that the printing materials are somewhat different. The printing materials of an ordinary printer are ink and paper, while a 3D printer is equipped with different "printing materials" such as metal, ceramic, plastic, and sand, which are real raw materials. After the printer is connected to the computer, through computer control, the "printing materials" can be stacked layer by layer, and finally the blueprint on the computer can be turned into a physical object.

[0004] Referring to Chinese Patent, the "3D printer material outlet head capable of accurately controlling the material output volume" with the application number: "CN213472213U", the utility model discloses a 3D printer material outlet head capable of accurately controlling the material output volume, including a housing.

All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0024] Please refer to Figures 1-4 , the present invention provides a technical solution, which specifically includes the following embodiments:

[0025] Embodiment 1:

[0026] A 3D printer material outlet head capable of accurately controlling the material output amount includes a first connecting plate 2. A protective frame 1 is fixedly connected to the top of the first connecting plate 2. An electric closing valve 4 is movably arranged on the top of the protective frame 1. A first connecting rod 12 is fixedly connected to the inner cavity of the first connecting plate 2. A transmission assembly 5 is fixedly sleeved on the surface of the first connecting rod 12. A bearing seat 10 is movably arranged on the top of the first connecting plate 2. A moving ring 11 is movably sleeved on the surface of the bearing seat 10 through a bearing;

[0027] The transmission assembly 5 includes a second connecting plate 501. A first internal gear ring 502 is movably sleeved on the surface of the second connecting plate 501. A second internal gear ring 507 is fixedly connected to the bottom of the first internal gear ring 502. A first ratchet 508 is meshed with the inner ring of the second internal gear ring 507. A second ratchet 509 is meshed with the surface of the first ratchet 508. The inner cavity of the second ratchet 509 is fixedly connected to the surface of the first connecting rod 12. A second connecting rod 9 is fixedly connected to the inner cavity of the first ratchet 508. The surface of the second connecting rod 9 is movably connected to the inner cavity of the moving ring 11 through a bearing;

[0028] Through the arranged electric closing valve 4, the material can enter the material conveying pipe 6. Through the arranged material usage monitor 8, when the materials in each pipeline reach the preset value, the electric closing valve 4 starts to close to complete the material conveying. At this time, by starting the servo motor 503, the servo motor 503 drives the rotating rod 505 to rotate, thereby driving the third ratchet 506 to rotate, and thus driving the first internal gear ring 502 to rotate, making the second internal gear ring 507 rotate. Since the second ratchet 509 is in a fixed state, the six first ratchets 508 start to perform a planetary orbiting motion to inject the material into the material outlet 3. Through the arranged material outlet 3, the mixing of the material is completed. At this time, the mixed material is then ejected to complete 3D printing.

[0029] The surface of the second connecting rod 9 is movably sleeved with a moving plate 7 through a bearing. A material consumption monitor 8 is fixedly arranged on the top of the moving plate 7. The output end of the material consumption monitor 8 is electrically connected to the receiving end of the electric closing valve 4. A material conveying pipe 6 is fixedly connected to the inner cavity of the moving plate 7, and a discharging device 3 is fixedly connected to the inner cavity of the first connecting plate 2;

A sensor can sense the measured information and transform the sensed information into an electrical signal or other required form of information output according to a certain rule to meet the requirements of information transmission, processing, storage, display, recording and control, etc.

[0031] The electric closing valve 4 is an electric valve. Simply put, it uses an electric actuator to control the valve, thereby realizing the opening and closing of the valve. It can be divided into two parts: the upper part is the electric actuator, and the lower part is the valve. The electric valve is usually connected by an electric actuator and a valve. After installation and debugging, it becomes an electric valve. The electric valve uses electric energy as power to connect the electric actuator to drive the valve, realizing the opening, closing and regulating actions of the valve, so as to achieve the purpose of opening or regulating the pipeline medium.

[0037] The third ratchet wheel 506 rotates, thereby driving the first internal gear ring 502 to rotate, causing the second internal gear ring 507 to rotate. Since the second ratchet wheel 509 is in a fixed state, the six first ratchet wheels 508 start to make a planetary orbiting motion, driving the material conveying pipes 6 to inject materials into the discharging device 3 in batches.

[0038] The number of the first ratchet wheels 508 is six, and the six first ratchet wheels 508 are distributed in a circular array.

[0039] A servo motor 503 is fixedly arranged at the top of the L-shaped plate 504, and the output end of the servo motor 503 is fixedly connected to the top of the rotating rod 505;

[0040] By providing the servo motor 503, the device is provided with a power source, facilitating the use of the device.

[0041] Meanwhile, the content not described in detail in this specification belongs to the prior art well-known to those skilled in the art.

[0042] During operation, when it is necessary to inject materials, through the provided electric shut-off valve 4, the materials can enter the material conveying pipe 6. Through the provided material monitor 8, when the materials in each pipeline reach the preset value, the electric shut-off valve 4 starts to close, completing the conveying of the materials. At this time, by starting the servo motor 503, the servo motor 503 drives the rotating rod 505 to rotate, thereby driving the third ratchet wheel 506 to rotate, and thus driving the first internal gear ring 502 to rotate, causing the second internal gear ring 507 to rotate. Since the second ratchet wheel 509 is in a fixed state, the six first ratchet wheels 508 start to perform a planetary orbiting motion, injecting the materials into the discharger 3. Through the provided discharger 3, the mixing of the materials is completed, and then the mixed materials are sprayed out to complete 3D printing.
