A rotatable switchable 3D printing nozzle

Abstract

The invention discloses a rotary switching 3D printing nozzle. The rotary switching 3D printing nozzle comprises a hanger, a gear system and a printing head, wherein the gear system is rotatably arranged on the hanger, the printing head is movably arranged on the hanger by virtue of a universal mechanism, the gear system is connected to the back end of the printing head by virtue of a swing rod device, and a motor for driving the gear system is arranged in the swing rod device. According to the rotary switching 3D printing nozzle, a planetary gear is driven to rotate by the motor, so that a gear system mounting plate is driven to rotate for a certain angle; the planetary gear of the gear system rotates around a sun gear, and the printing head is driven to rotate around a rotating shaft by virtue of the universal mechanism, so that the other printing head is vertically arranged downwards; when the printing head is converted, the position of the previous printing head is the lowest point of a movement track, so that the problem of collision of the printing head and a printing material is avoided during conversion; and the rotary switching 3D printing nozzle has the advantages of simple structure and convenience in operation.

Description

technical field [0001] The invention relates to a 3D printer print head, in particular to a rotatable and switchable 3D print print head. Background technique [0002] At present, in the printing process of the same kind of multi-print heads on the market, because the print heads are placed horizontally, there may be rubbing problems during the printing process, which will affect the printing quality. Contents of the invention [0003] The present invention aims to solve the problem of material rubbing caused by the switching of multiple print heads during the printing process, complete the switching between different print heads by means of the rotation of the planetary wheel and the transmission of the universal mechanism, and solve the problem that may occur during the printing process of ordinary multiple print heads. The problem of rubbing material on the print head. [0004] The present invention adopts following technical scheme to realize: [0005] A rotatable sw...
