Wire-extruding assembly of 3D printer

Abstract

The invention discloses a wire-extruding assembly of a 3D printer. The wire-extruding assembly of the 3D printer comprises an extruding machine base, an extruding head assembly and a wind-leading structure. The extruding head assembly comprises a square extruding base fixed to a base body. A screw hole penetrating vertically and a heating pipe hole penetrating horizontally are formed in the extruding base. A thermistor hole is formed in one side of the heating pipe hole. An extruding head and an extruding throat pipe are arranged at the two ends of the screw hole in the extruding base respectively. The end opening of the extruding head abuts against the end opening of the extruding throat pipe in a contacting mode in the screw hole. The other end of the extruding throat pipe is connected with a fixed aluminum piece which is fixed on the base body. The extruding throat pipe comprises a pipe body with outer threads. One end of the pipe body is provided with a heat isolation part of which the inner portion is through, and a cone-shaped opening is formed in the other end of the pipe body. The wind-leading structure comprises a wind-leading nozzle and a cooling fan. The wind-leading nozzle comprises a cone-shaped nozzle body. The cooling fan is arranged at the inlet end of the cone-shaped nozzle body, and a flat wind nozzle is arranged at the outlet end of the cone-shaped nozzle body. A fixing part is arranged on one side of the inlet end, and the fixing part and the fixed base are fixedly connected. According to the wire-extruding assembly of the 3D printer, the wire plugging problem is solved, meanwhile, cooling is achieved, and the quality of a printed product is improved.

Description

technical field [0001] The invention relates to a wire extruding component on a 3D printer. Background technique [0002] 3D printers are becoming more and more common in the market, which has affected the global manufacturing revolution. In the past, the design of components was completely dependent on whether the production process can be realized. At that time, the production process is no longer considered, and the design of any complex shape can be realized by 3D printers. It can directly generate objects of any shape from computer graphics data without machining or molds, thereby greatly shortening the production cycle of products and improving productivity. Although it still needs to be perfected, the market potential of 3D printing technology is huge, and it is bound to become one of the many breakthrough technologies in the future manufacturing industry. [0003] The basic principle of a 3D printer is to heat and melt raw materials and then cool and solidify to sh...

AI Technical Summary

Problems solved by technology

[0004] In the process of 3D printing, the printing nozzle on it is prone to wire clogging. In the conventional design, the diameters of both ends of the throat are the same. After a long time, I still couldn’t enter the throat accurately. During the hard process, the consumable wire was bent. Silk

This is a very inhumane design, which creates a bad experience for users

[0005] In addition, during the process of heating and dissolving, consumables are easy to form blockage inside the throat, which not only affects the efficiency and quality of printing, but also causes loss of consumables. Regular maintenance is often required to prevent blockage, which is very inconvenient

[0006] In addition, the short cooling time during the printing process leads to the failure of shaping and the inability to print a good finished product. It is easy to appear rough surface, and the product quality is reduced, which needs to be improved.
