Self-cleaning 3D digital printer smooth in feeding and convenient for raw material recovery

Abstract

The invention provides a self-cleaning 3D digital printer smooth in feeding and convenient for raw material recovery. The self-cleaning 3D digital printer comprises a 3D digital printer body, a support is welded to one side of the 3D digital printer body, a transverse pipe is welded to the top of the support, a hopper is welded to the top of the transverse pipe, a discharging valve is installed at the bottom of the hopper, a printing head is installed on the inner side of the 3D digital printer body, a conical barrel is welded to the top of the printing head, an air pump is welded to one end of the transverse pipe. According to the self-cleaning 3D digital printer smooth in feeding and convenient for the raw material recovery, filtering equipment does not need to be used, so that powder raw materials are prevented from blocking a filtering mechanism, smooth airflow can be kept, the powder raw materials are prevented from blocking a feeding pipe, the powder raw materials can be recycled, material waste is avoided, residual water after cleaning can be effectively dried, the cleaning efficiency is improved, cleaning equipment does not need to be additionally arranged, the cleaning efficiency is improved, an added cleaning device is not needed, the equipment investment is reduced, and the self-cleaning 3D digital printer is suitable for 3D digital printing.

[0002] 3D digital printer is a kind of digital model file-based, using powder Adhesive materials such as metal or plastic, through layer-by-layer Print It is often used to manufacture models in mold manufacturing, industrial design and other fields, and then gradually used in the direct manufacture of some products. There are already parts printed using this technology. part , the patent application number is CN201511020661.1, which discloses a multi-material 3D printer. The existing 3D digital printers basically have the advantages of long continuous working time, fast 3D printing speed, high 3D printing precision, complex 3D printing structure, The equipment has the advantages of solid structure and long service life, which can meet the requirements of 3D printing for various products. However, for the existing 3D digital printers, on the one hand, in order to facilitate the transportation of powdery raw materials, it is necessary to blow air to make them Powdered raw materials are fluid, and it is necessary to install powder collection and filtering equipment at the print head, and then it is necessary to make the cleaning equipment perform real-time cleaning operations on the filtering device, which increases energy consumption. The material is blocked in the feeding tube. On the other hand, when the printing job is completed, there is still a certain amount of powder material on the print head, which is not conducive to recycling it into the hopper. On the other hand, when the powder material needs to be replaced, it is necessary to clean the hopper, etc. Equipment cleaning operations require additional cleaning equipment or manual cleaning, increasing equipment investment or wasting manpower
