3D printer head with material circulation function

Abstract

The 3D printer head with the material circulation function comprises a printer barrel, a main runner and a circulation runner are arranged in the printer barrel, a circulation discharging port and a circulation feeding port are formed in the circulation runner, the circulation discharging port communicates with the feeding end of the main runner, and the circulation feeding port can communicate with the discharging end of the main runner; the circulating conveying power mechanism is used for conveying materials at the circulating feed port to the circulating discharge port; and the main runner conveying mechanism extends into the main channel. By adding the circulating flow channel with a continuous circulating function and the circulating conveying power mechanism, the main flow channel and the circulating flow channel are connected, circulating reciprocating flow of materials between the main flow channel and the circulating flow channel is achieved, the processing time of the materials in a machine barrel of the printer is prolonged, the blending uniformity of the materials is improved, and the reaction time of the materials is prolonged and regulated; the components of the composite material are regulated and controlled by monitoring reaction materials on line; the flowability of materials near the printing head is improved, material accumulation is reduced, and the plug problem is effectively solved.

Description

technical field [0001] The invention relates to the field of electromechanical manufacturing equipment, in particular to a 3D printer head with a material circulation function, a printer device and a control method. Background technique [0002] 3D printing technology refers to the technology of printing the drawn three-dimensional model with the help of three-dimensional design software, and printing the raw material layer by layer to form the parts. The raw materials of 3D printing mainly include metals, inorganic non-metals, and polymer materials. At present, 3D printing technology is widely used in the field of single material, but there is a lack of development and application of composite material 3D printing technology, mainly due to: [0003] (1) The research and development process of 3D printing composite materials is complicated. The new composite materials need to cooperate with the 3D printing process to reverse the formula or composition of the composite mater...

Problems solved by technology

[0009] The above technical solution: by adding a circulation flow channel with continuous circulation function and a circulation transmission power mechanism in the printer barrel, the main flow channel and the circulation flow channel are connected, and the material in the machine head is realized between the main flow channel and the circulation flow channel. The "reciprocating" flow improves the reaction and processing time of materials in the printer barrel. On the one hand, it can improve the blending performance of materials (that is, dispersibility), and on the other hand, it can accurately control the reaction time of materials, which solves the problem of existing 3D printers. It is the problem of uneven mixing of composite materials and uncontrollable blending / reaction time in vertical printers
