Description
Technical Field
The invention relates to a three-dimensional lamination double-printing device, which is an industrial production machine for molding products in a lamination mode.
Background
The principle of additive manufacturing, known as 3D printing, is one of the forming and manufacturing techniques that have been developed vigorously with attention paid in recent years, and is to use a nozzle to eject a raw material heated to a molten state onto a platform according to a drawn product three-dimensional figure file, so as to form a desired product layer by layer.
In the lamination manufacturing, the nozzle aperture of the nozzle is one of the important factors affecting the printing efficiency and quality, when the nozzle with larger aperture is used, the amount of the material ejected per unit time is larger, and therefore the printing speed is faster, but relatively when the product details are too fine or even smaller than the nozzle aperture, the product details may not be displayed perfectly, and when the nozzle with smaller aperture is used, although the product details can be processed perfectly, the amount of the material ejected per unit time is smaller, and the printing speed is slower.
Most of the existing 3D printers are equipped with only a single nozzle, and although technicians can replace nozzles with different apertures according to the detailed requirements of the products, they cannot simultaneously consider the printing speed and the detail presenting capability.
In view of the above drawbacks, the present inventors thought that there is a need for correction, and then, based on years of experience in related technologies and product design and manufacture, the present invention provides a three-dimensional multi-layer double printing apparatus, which corrects the product structure to improve the product quality, after continuous efforts, while maintaining the excellent design concept.
Disclosure of Invention
The present invention provides a three-dimensional laminated dual-line printing device, which has two nozzles with different apertures, and can freely switch between the two nozzles during the printing process, thereby simultaneously considering the printing speed and the detail presenting capability.
In order to achieve the above object, the present invention discloses a three-dimensional build-up double printing apparatus, comprising:
a three-dimensional driving unit;
the feeding unit is connected with the three-dimensional driving unit;
a nozzle unit having a nozzle base connected with the feeding unit, the nozzle base having a first and a second longitudinal sliding grooves, a switching driver connected with a linkage member, a deflection member pivoted to the nozzle base and pivoted to the linkage member, a first and a second nozzle respectively pivoted to the first and the second sliding grooves and capable of moving up and down, a first and a second nozzle respectively provided at the lower ends of the first and the second nozzles and having different orifices, and a switching driver for driving the linkage member to move to drive the deflection member to deflect to different angular positions and further to drive the first and the second nozzles to move to a working position or a standby position higher than the working position The first spray head and the second spray head are respectively positioned at the working position and the standby position, so that a height drop exists between the first spray nozzle and the second spray nozzle;
a bearing platform connected with the three-dimensional driving unit.
The three-dimensional driving unit is provided with a base frame, a vertical frame is fixedly arranged on the base frame, a movable frame capable of moving up and down is arranged beside the vertical frame, the base frame is provided with a first displacement mechanism, the vertical frame is provided with a second displacement mechanism connected with the movable frame, the movable frame is also provided with a third displacement mechanism, the feeding unit is connected with the third displacement mechanism, the bearing platform is movably arranged on the base frame, and the bearing platform is connected with the first displacement mechanism.
Wherein, a material conveying channel is defined in the nozzle base of the nozzle unit, the material conveying channel is simultaneously communicated with the material supply unit, the first chute and the second chute, the first nozzle is internally defined with a first nozzle channel communicated with the spraying port of the first nozzle from the outer side, the second nozzle is internally defined with a second nozzle channel communicated with the spraying port of the second nozzle from the outer side, and when the first nozzle or the second nozzle is positioned at the working position, the first nozzle channel or the second nozzle channel is communicated with the material conveying channel.
The feeding unit is provided with a material pipe, a material pushing mechanism is arranged in the material pipe, and the material pipe is provided with a heating module.
Wherein, the material pipe is communicated with a powder feeding hopper which is used for placing powder or granular raw materials.
Therefore, when the invention carries out printing operation, the material supply unit heats and melts the raw materials and supplies the raw materials to the nozzle unit, the three-dimensional driving unit enables the nozzle unit to generate three-dimensional displacement relative to the bearing platform, and the nozzle unit can print the required products on the bearing platform when spraying the raw materials again.
In the printing process, the first nozzle or the second nozzle can be switched to use when different parts of the product to be printed are not needed to be considered in detail, for example, when the interior of the product to be printed is printed, the first nozzle can be switched to the working position if the nozzle opening of the first nozzle is larger, the printing speed can be accelerated due to the larger nozzle opening of the first nozzle, and when the detail characteristics of the surface of the product to be printed are printed, the second nozzle can be switched to the working position, and the detail characteristics of the product can be presented more perfectly due to the smaller nozzle opening of the second nozzle. In addition, when the first nozzle and the second nozzle are respectively positioned at the working position and the standby position, a height difference exists between the first nozzle and the second nozzle, so that the nozzle to be hit can be prevented from being scraped to a semi-finished product in the line printing.
Compared with the conventional 3D printer only provided with a single nozzle, the invention has the first nozzle and the second nozzle which can be freely switched and used and have different apertures, so that the first nozzle and the second nozzle can be switched and used when different parts of a product are printed, and the printing speed and the printing quality can be simultaneously considered, thereby the invention is a very progressive creation.
