Example Embodiment

[0039] Hereinafter, the present invention will be further described with reference to the drawings and specific implementations:

[0040] See figure 1 , 2 3. The print head transmission mechanism of the present invention includes a platform 10, a mounting seat 30, three transmission components 20, and a controller (not shown). The platform 10 is mainly used to place printing workpieces and serves as the installation basis for the entire transmission mechanism. The two transmission components 20 cooperate to drive the mounting seat 30 with the nozzle 40 fixed to move in the height direction and the horizontal direction.

[0041] Three transmission components 20 are evenly distributed on the periphery of the platform 10. Each transmission component 20 includes a motor seat 21, a drive motor 22, two guide rods 23, a fixed seat 24, a driving pulley 25, a driven pulley 26, and a synchronous The belt 27, the sliding seat 28 and the two connecting rods 29, wherein the motor seat 21 is fix...

Abstract

The invention discloses a nozzle transmission mechanism for a 3D printer. The nozzle transmission mechanism comprises a platform used for holding a workpiece, a mounting seat which is positioned above the platform and is used for fixing a nozzle, more than three transmission components distributed at the periphery of the platform, and a controller used for controlling each driving motor, wherein each transmission component comprises a guide rod which extends along the height direction, a sliding seat arranged on the guide rod in a sliding mode, a driving motor used for driving the sliding seat to move up and down along the guide rod, and a connecting rod; and two ends of the connecting rod are respectively connected with the mounting seat and the sliding seat in a universal hinge mode. Three or more than three guide rods in the vertical direction are arranged only, the sliding seat on the guide rods is driven by the motor, the nozzle is driven to move in the height direction and the horizontal direction through differential motion among the sliding seat, and compared with the conventional three-axis association transmission mechanism, the nozzle transmission mechanism has the advantages of simple structure, small occupied space, high operating precision and the like, the 3D printing efficiency can be improved, and the defective percentage of the workpiece is reduced.

Description

[0001] technical field [0002] The invention relates to the technical field of 3D printing, in particular to a nozzle transmission mechanism of a 3D printer and a 3D printer having the mechanism. [0003] Background technique [0004] 3D printing technology is a rapid prototyping technology for workpieces. It is based on the digital model file of the workpiece, using materials with viscous properties after heating and softening, such as metal or plastic, to form the workpiece by layer-by-layer printing. [0005] Nozzle 3D printers are used to output consumables. During the printing process, the nozzle is required to be able to move arbitrarily on the three coordinate axes in space to deal with workpieces with different external contours. Most of the existing 3D printer nozzle transmission mechanisms use the transmission mechanism of the traditional three-axis linkage machine tool, which includes axes along the X, Y, and Z directions, and each axis is equipped with a drive ...
