Embodiment Construction

[0029] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments, but the present invention is not limited to these embodiments.

[0030] Such as Figure 1 to Figure 7 As shown, a 3D printer with a multi-nozzle automatic conversion system includes a frame 6, and the multi-nozzle automatic conversion system is arranged on the frame 6. For the convenience of description, the horizontal direction is defined as the X axis, and the vertical direction is defined as The Y axis, which defines the vertical direction as the Z axis. The multi-nozzle automatic conversion system includes a nozzle storage mechanism 2, a manipulator mechanism 3 and a mobile nozzle device 1 moving along the X and Z directions. The manipulator mechanism 3 is arranged between the nozzle warehouse mechanism 2 and the mobile nozzle device 1.

[0031] Such as figure 1 and image 3 As shown, the nozzle storage mechanism 2 includes a rot...

Abstract

The invention discloses a 3D printer with a multi-nozzle automatic switching system, which includes a frame, and the multi-nozzle automatic switching system is arranged on the frame. The mobile sprinkler device moving in the Z direction, the manipulator mechanism is arranged between the sprinkler library mechanism and the mobile sprinkler device; the sprinkler library mechanism includes a rotating bracket and several standby sprinklers arranged along the circumference of the rotating bracket, and the mobile sprinkler device includes a moving bracket , the printing nozzle and the clamping mechanism that is arranged on the mobile bracket and clamps and positions the printing nozzle. The manipulator mechanism includes a manipulator for clamping and releasing the printing nozzle and the standby nozzle, and drives the manipulator in the nozzle library mechanism and the mobile nozzle device. Rotary drive unit for position switching. The invention has simple structure and small volume, and can realize multi-nozzle, multi-material and multi-color 3D printing.

Description

technical field [0001] The invention belongs to the technical field of 3D printers, in particular to a 3D printer with a multi-nozzle automatic switching system. Background technique [0002] 3D printing technology is a technology based on 3D digital model files, using bondable materials such as powdered metal or plastic, to manufacture objects by layer-by-layer printing. The common 3D printers currently on the market mainly print with a single nozzle, or integrate multiple nozzles together, and its printing action is similar to that of a single nozzle. Nozzles, the defect of this method is that due to the position limitation of multiple nozzles, when one of the nozzles is working, the other nozzle needs to move to avoid the model in order to prevent scratching the model. In long-term use, frequent movement will cause fatigue loss of the connecting parts, resulting in errors. At the same time, since the nozzles are integrated on the nozzle, affected by the position and rel...
