Abstract

The invention discloses a material conveying and spraying device for 3D printing. The material conveying and spraying device for 3D printing comprises a mounting main body frame and a fixing frame fixed to one end of the mounting main body frame, a mounting and dismounting structure is mounted on one side of the mounting main body frame, a motor is mounted on one side of the mounting main body frame, and a rotating shaft is mounted at the output end of the motor through a coupler. A driving gear is fixed to the end, away from the motor, of the rotating shaft, a driven gear is engaged with one side of the driving gear, a conveying shaft is arranged at the center position of the driven gear, the two ends of the conveying shaft are each sleeved with a driving disc in the axial direction, and a short guide cylinder is fixed to one side of the fixing frame. The side, away from the driving discs, of the conveying shaft is fixedly connected with one side of the mounting main body frame. According to the material conveying and spraying device for 3D printing, the mounting and dismounting structure is arranged on the mounting main body frame, the conveying shaft is arranged on the fixing frame, and a fixing disc is directly arranged on a positioning column on the surface of the printing device, so that the phenomena of material breakage and the like are avoided, and meanwhile the spraying position can be conveniently and randomly adjusted.

Description

technical field [0001] The invention relates to the field of 3D printing devices, in particular to a material injection device for 3D printing. Background technique [0002] With the development of society and the continuous progress of human beings, 3D printing is a kind of rapid prototyping technology, also known as additive manufacturing. It is based on digital model files and uses bondable materials such as powdered metal or plastic. The technology of constructing objects by layer-by-layer printing 3D printers uses nozzles to print, because some parts need to use more materials, and the injection volume of the nozzles is fixed, so the injection volume of the nozzles cannot be adjusted according to needs. , therefore, the application of the material injection device for 3D printing is more important. [0003] In China Patent Application Publication (Announcement) No.: CN212372713U discloses a 3D printing feeding injection device, which relates to the technical field of f...
