Example Embodiment

[0023] See figure 1 with 2 , The self-cleaning 3D printer consumable nozzle of the present invention includes:

[0024] The conduit 1 includes a first pipe 3 for introducing consumables used, a second pipe 4 for heating the consumables, and a third pipe 5 for introducing clean liquid or gas;

[0025] The nozzle 2 has a truncated cone-shaped cavity and a nozzle 14. The nozzle 2 is located at the lower end of the pipe 1 and has a first partition 7. The nozzle 2 has two layers of pipe walls, a fourth pipe 12 for introducing clean liquid or gas is formed between the two pipe walls, and the fourth pipe 12 is in communication with the third pipe 5.

[0026] The feed pipe 8, below the partition 7, communicates with the first pipeline 3 through the through hole 6 on the first partition, and the consumable output port 9 of the feed pipe 8 is at the nozzle 14 or more, the lower end surface of the feed pipe 8 has a second partition 10, which separates the cavity into two separate cavities; the...

Abstract

The invention provides a 3D printer consumable spray head capable of achieving self-cleaning. The spray head comprises a guiding pipe, a spray nozzle and a material conveying pipe. The guiding pipe comprises a first pipeline for guiding-in of used consumables, a second pipeline for heating the consumables and a third pipeline for guiding-in of clean liquid or gas; the spray nozzle is provided with a circular-table-shaped cavity and a first spray port, and the spray nozzle is located at the lower end of the guiding pipe and provided with a first partition plate and two layers of pipe walls; a fourth pipeline for guiding-in of the clean liquid or gas is formed between the two layers of pipe walls and communicates with the third pipeline; the material conveying pipe is arranged below the first partition plate and communicates with the first pipeline through a via hole in the first partition plate; a consumable output port of the material conveying pipe is located above the spray port, and a second partition plate is arranged on the lower end face of the material conveying pipe and isolates the cavity into two partitioned cavity bodies; and a consumable output port is formed in the center of the second partition plate, a plurality of through holes surrounding the consumable output port are formed in the annular area of the edge of the second partition plate and communicate with the fourth pipeline.

Description

technical field [0001] The invention relates to the field of printers, in particular to a consumable nozzle structure for preventing nozzle clogging of a 3D printer. Background technique [0002] The biggest difference between a 3D printer and a traditional printer is that the "ink" it uses is a real raw material. There are various forms of stacking thin layers, and there are various types of media that can be used for printing, from a variety of plastics to metals, ceramics and rubber. class of substances. Some printers can also combine different media so that the printed object is hard on one end and soft on the other. [0003] Some 3D printers use an "inkjet" method. That is, a very thin layer of liquid plastic substance is sprayed onto the casting tray using a printer nozzle, and this coating is then exposed to ultraviolet light for treatment. The mold tray is then lowered a very small distance for the next layer to be stacked up. [0004] Others use a technique call...
