Description

Technical Field

[0001] The present invention relates to the technical field of 3D printers, and particularly to a full-color 3D printer. Background Art

[0002] A full-color 3D printer is a device that can use a variety of different materials in the same printing process and simultaneously print different colors. A 3D printer, also known as a three-dimensional printer (3DP), is a kind of additive manufacturing technology, that is, a machine of rapid prototyping technology. The working principle of a 3D printer is basically the same as that of an ordinary printer. It stacks "printing materials" layer by layer through computer control, and finally turns the blueprint on the computer into a physical object. This technology is often used in the fields of mold manufacturing, industrial design, etc. to manufacture models or for the direct manufacturing of some products. During the process of realizing full-color printing, the pigments inside the pigment storage cavity are prone to precipitation during storage, resulting in uneven pigments and reducing the printing effect.

[0003] As described in a full-color 3D printer (authorization announcement number: CN112959654B) published on the patent network, this full-color 3D printer includes a "printer body, a printing nozzle, a pigment storage mechanism", etc. to achieve printing work.

[0004] Regarding the above description, the applicant believes there are the following problems: This full-color 3D printer uses a printer body, a printing nozzle, a pigment storage mechanism, etc. to achieve printing work. During the use of this printer, different pigments are stored through a pigment storage cavity, and only two colors can be stored each time. The types of storage are limited, and it is not convenient to clean the inside of the pigment storage cavity after use. When used for a long time and storing different pigments, the old and new pigments are mixed or caked, which affects the printer itself and the printing quality, and the feeding amount of the pigment cannot be controlled, further affecting the printing effect. Therefore, this printer needs to be improved. Summary of the Invention

[0015] According to the above technical solution, the left side of the spring is fixedly connected to the inner side of the mounting frame, and the right side of the spring is fixedly connected inside the rectangular frame. The bottom of the first sealing cover is in contact with the top of the storage tank, which is convenient for ensuring the stability of the first sealing cover during use under the action of the spring and at the same time convenient for controlling the opening and closing state of the first sealing cover.

[0016] Compared with the prior art, the beneficial effects achieved by the present invention are as follows: 1. For this full-color 3D printer, through the arranged stirring assembly, when the printer body is in use, the three material storage tanks are respectively slidably connected to the inside of the mounting seat through the fixing blocks, so that the material storage tanks are in a stable state, and the bottoms of the material storage tanks are inside the connecting heads. At the same time, it is convenient for installation and disassembly during subsequent cleaning of the material storage tanks. When different-color pigments are respectively put into the three material storage tanks, the first servo motor drives the second rotating rod, drives the first pulley, and makes the second pulley rotate through the transmission belt, and then drives the first rotating rod and the main gear to rotate, meshes with the auxiliary gear, so that the rotating shaft and the stirring rod stir the materials in the material storage tank. When the stirring rod rotates, it will contact the inner side of the material storage tank, further cleaning the inner wall of the material storage tank, avoiding material precipitation and stratification, ensuring uniform mixing of the materials, providing guarantee for printing high-quality and color-uniform 3D models, and can provide rotational power for the material feeding assembly under the action of the first pulley, the second pulley, the transmission belt and the first rotating rod. When the insertion rod in the material feeding assembly is inserted into the first rotating rod and the third rotating rod, the third rotating rod can follow the first rotating rod to rotate, so as to realize the material feeding work of the pigments in the material storage tank, carry out the printing work, and realize the linkage effect between the stirring assembly and the material feeding assembly, improving the use efficiency and quality of the printer body.

[0017] 2. For this full-color 3D printer, through the arranged material feeding assembly, when the printer body is in use and when the pigments in the material storage tank need to be fed for printing after being stirred, the second servo motor drives the threaded rod to rotate, so that the moving plate moves left and right in the connecting frame, and then drives the insertion rod to move in the limiting grooves of the first rotating rod and the third rotating rod, realizing the connection or separation between the third rotating rod and the first rotating rod. When the insertion rod is inserted into the first rotating rod and the third rotating rod, the third rotating rod can follow the first rotating rod to work. When the third rotating rod rotates, it drives the metering plate to rotate through the first bevel gear and the second bevel gear, realizing precise control of the rotation angle of the metering plate, and further realizing precise control of the material feeding amount of the pigments in the material storage tank. This helps to precisely control the usage amount of different-color materials, ensure the accuracy of color ratio during the printing process, and improve the printing quality. There are three groups of the second bevel gear and the metering plate, which are respectively arranged around the first bevel gear and are respectively rotatably connected to the inside of the material storage tank, so that the feeding control of the three groups of material storage tanks can be carried out simultaneously, realizing the synchronous feeding of multiple-color materials, improving the printing efficiency, and at the same time realizing the linkage work of the stirring assembly and the material feeding assembly under the driving action of the first servo motor. And when the insertion rod is away from the inside of the first rotating rod, it can prevent the third rotating rod from following the first rotating rod to work, without affecting the first rotating rod to drive the stirring rod to work.

[0018] 3. For this full-color 3D printer, through the set forming mechanism, when the pigments in the storage tank are stored and stirred completely, the air cylinder can push the moving seat to move left and right on the sliding rod, and the electric telescopic rod can adjust the height of the liquid storage device and the printing nozzle, enabling the printing nozzle to print at different positions, adapting to the printing requirements of 3D models with different shapes and sizes, improving the flexibility and adaptability of printing. The conveyor transports the materials in the storage tank to the liquid storage device through the delivery pipe and the connector, and then sprays them out of the printing nozzle through the hose. The three groups of connectors, delivery pipes, and hoses are respectively connected to different storage tanks and printing nozzles, capable of simultaneously transporting multiple-color materials, with stable transportation, ensuring uninterrupted material supply during the printing process, guaranteeing the printing quality. The three nozzles can work simultaneously, respectively responsible for printing tasks of different colors. Compared with single-nozzle or double-nozzle printers, it can greatly improve the printing speed and shorten the printing time when printing color models.

[0019] 4. For this full-color 3D printer, through the set sealing mechanism, when the storage tank is in use and contains pigments inside, the spring in the rectangular frame pushes the mounting frame and the first sealing cover, making them closely fit the top of the storage tank. The first sealing cover cooperates with the second sealing cover to further enhance the sealing effect, preventing the materials in the storage tank from getting damp, oxidized, or mixed with impurities, ensuring stable material performance and extending the service life of the materials. When it is necessary to remove the storage tank for cleaning, just pull the mounting frame and the first sealing cover to the right, making the mounting frame slide around the fixed rod to squeeze the spring, which can avoid blocking the storage tank and separate the first sealing cover from the storage tank. The operation is simple and convenient. The sealing mechanism ensures the quality of the materials in the storage tank, providing high-quality materials to be stirred for the stirring component. During the stirring and feeding processes, the sealing mechanism continuously functions to prevent the materials from being affected by external factors. Only when it is necessary to add materials, the first sealing cover is opened by overcoming the elastic force of the spring, and it returns to the sealed state after the addition is completed, ensuring the stable quality of the materials throughout the printing process and forming a linkage effect with the stirring component and the feeding component.
