Liftable and rotatable printing platform of 3D printing machine

Abstract

The invention discloses a liftable and rotatable printing platform of a 3D printing machine and relates to the field of 3D printing machines. The liftable and rotatable printing platform comprises a bottom plate, a lifting mechanism and a rotating carrying table mechanism. Two gear boxes are arranged on the bottom plate. The lifting mechanism is composed of a driving motor, a driving shaft and screw rods. The driving motor is fixedly installed on the bottom plate. The driving shaft is fixedly connected with an output shaft of the driving motor. The driving shaft is in rotational connection with the two gear boxes. The driving shaft is provided with a first driving bevel gear and a second driving bevel gear. The two screw rods are arranged, and driven bevel gears are fixedly arranged at thetail ends of the screw rods. The two screw rods are in rotational connection with the two gear boxes. The driven bevel gear of one screw rod is engaged with the first driving bevel gear, and the driven bevel gear of the other screw rod is engaged with the second driving bevel gear. The rotating carrying table mechanism is composed of an auxiliary platform, a rotating motor and a carrying table. By means of the printing platform, lifting can be achieved, rotating can also be achieved, and the liftable and rotatable printing platform can be better matched with the whole 3D printing machine to complete printing work.

Description

technical field [0001] The invention relates to the field of 3D printers, in particular to a liftable and rotatable printing platform of the 3D printer. Background technique [0002] 3D printer, also known as three-dimensional printer (3DP), is a cumulative manufacturing technology, that is, a machine of rapid prototyping technology. It is based on a digital model file and uses special wax, powdered metal or plastic to bond Materials, by printing layers of adhesive materials to make three-dimensional objects, at this stage 3D printers are used to manufacture products, the technology of constructing objects by printing layer by layer, the principle of 3D printers is to put data and raw materials into 3D In the printer, the machine will make the product layer by layer according to the program. The biggest difference between the 3D printer and the traditional printer is that the "ink" it uses is a real raw material. There are various forms of stacking thin layers, which can be ...

Problems solved by technology

[0003] Most of the printing platforms of existing 3D printers can only be lifted or rotated, but not have the functions of lifting and rotating at the same time. Therefore, designing a printing platform that can be lifted and rotated will better match the 3D printer to complete the analysis. print job
