A rotary 3D printer nozzle switching device

Abstract

The invention discloses a nozzle switching device of a rotary 3D printer, which comprises a support rod, a bottom support plate, a wheel rail, a groove of the wheel rail, a heating head, a rotary disc, and the like. The support rod is fixedly installed on the bottom supporting plate, and the wheel rail is installed on the bottom supporting plate; the motor mounting base is fixedly installed on the bottom supporting plate, and a motor is installed above; the wheel turntable is installed on the bottom supporting plate through the wheel rail, and It can be rotated in the bottom supporting plate along the wheel rail; the heating head fixing seat is installed on the oblique side of the rotary table, the heating head is installed on the heating head fixing seat, and a feed port is installed above the heating head, and the bottom is installed There is an extrusion nozzle; the pinion gear is installed on the motor shaft and rotates synchronously with the motor, and the wheel rotating disc rotates together through the meshing between the large gear and the pinion gear. The invention can realize the rotary switching of multiple colors or multiple materials of the 3D printer, and the problem of color or material mixing will not occur during the switching process, and the rotary disc will not shake after switching.

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...
