Problems solved by technology

[0003] At present, the nozzles of 3D printers are directly heated, melted and extruded, and it is easy to have wire drawing during the printing process.
This situation is more serious in printers with two-color nozzles, which makes the printed model too rough. The printing quality is not high, and there is no way to widely use it in the market.

Abstract

The invention discloses a spray head capable of automatically closing a nozzle. The spray head comprises a material guide pipe, wherein one end of the material guide pipe is connected with a feeding port of a 3D printer, the other end of the material guide pipe is connected with the nozzle, the end, close to the nozzle, of the material guide pipe is embedded into a heating metal block, and the heating metal block is a square block with at least three through holes arranged on the side surface; a guide rail groove is formed in the outer circumference of the nozzle, the guide rail groove is rotatably connected with one end of a transmission rod, the other end of the transmission rod is hinged to one side of a baffle, a connecting shaft is further arranged at a discharging port of the nozzle,and the other side of the baffle is hinged to the connecting shaft; and the transmission rod moves on the guide rail groove to drive the baffle to move away from or shield the discharging port of thenozzle. According to the spray head, the baffle moves away from or shields the discharging port of the nozzle, so that the nozzle can be closed in time when a sensor detects that the 3D printer is about to convert the nozzle to print, and the situations of wire drawing and nozzle emptying are avoided; and meanwhile, the internal temperature of the nozzle can also be ensured, the smoothness of next wire drawing is increased, the printing quality is improved, and the practicability of a product is increased.

Description

technical field [0001] The invention relates to the technical field of 3D printing, in particular to a spray head capable of automatically closing nozzles. Background technique [0002] At present, 3D printing technology has become a modern trend. The new production method has changed some traditional processing methods and has begun to be widely used in various design fields. It is widely used in industrial design, and can complete the processing and printing production of a model in a short time, saving the development time of the designed product to the market. [0003] At present, the nozzles of 3D printers are all directly heated, melted and extruded, and wire drawing is easy to occur during the printing process. This situation is more serious in printers with two-color nozzles, which makes the printed model too rough. The printing quality is not high, and there is no way to widely use it in the market. Contents of the invention [0004] In view of the above problem...
