Problems solved by technology
[0002] With the development of human science and technology, 3D printers have been more and more used in the design field, especially industrial design, product mold opening, etc., and more and more 3D printers have appeared on the market, but most of the current 3D printers can only print single-color materials. If coloring is required, it can be achieved by inkjet printing and other methods. There are also single-head multi-color printers on the market, but it is difficult to solve the problem of mixing multiple materials in the heating head. question

The invention discloses a rotation type 3D printer spraying head switching device. The rotation type 3D printer spraying head switching device comprises a support rod, a bottom support plate, a wheel rail groove, heating head, a rotation disk and the like. The support rod is fixedly installed on the bottom support plate. A wheel rail is installed on the bottom support plate. A motor installation seat is fixedly installed on the bottom support plate, and a motor is installed on the motor installation seat. The rotation disk is installed on the bottom support plate through the wheel rail and can rotate in the bottom support plate along the wheel rail. Heating head fixing seats are installed on the inclined side face of the rotation disk. The heating heads are installed on the heating head fixing seats correspondingly, and feed inlets are installed on the heating heads correspondingly. Extrusion mouths are installed under the heating heads correspondingly. A small gear is installed on a motor shaft and rotates synchronously along with the motor, and he rotation disk rotates together through meshing between a large gear and the small gear. According to the rotation type 3D printer spraying head switching device, rotation type switching of multiple colors or multiple materials of a 3D printer can be achieved, the problem of mixing of the colors or the materials does not occur in the switching process, and after switching, the rotation disk does not shake.
Description
technical field [0001] The invention relates to a design of an extrusion head of a 3D printer, in particular to a nozzle switching device of a rotary 3D printer, which belongs to the technical field of 3D printing. Background technique [0002] With the development of human science and technology, 3D printers have been more and more used in the design field, especially industrial design, product mold opening, etc., and more and more 3D printers have appeared on the market, but most of the current 3D printers can only print single-color materials. If coloring is required, it can be achieved by inkjet printing and other methods. There are also single-head multi-color printers on the market, but it is difficult to solve the problem of mixing multiple materials in the heating head. question. Therefore, there is an urgent need for a printer nozzle switching device with simple structure, easy material conversion and no material mixing problem. Contents of the invention [0003...
