Adjusting device used for 3D printer

Abstract

The invention discloses an adjusting device used for a 3D printer. The device comprises two support frames. An installation plate is fixed between the two support frames. A first servo motor is fixedat a lower end of the installation plate. A first belt pulley is fixed on an output shaft of the first servo motor. Two sides of the first belt pulley are in transmission connection with second belt pulleys. Lead screws are fixed to centers of the two second belt wheels. The lead screws are located in the support frames. A lower end portion of each lead screw is rotatably connected with a bottom end of each support frame. The lead screws are in threaded transmission connection with moving blocks. A moving plate is welded between the two moving blocks. An installation frame is fixed in the middle of a lower end of the moving plate. A rotating mechanism is arranged in the middle of the installation frame, an angle adjusting mechanism is arranged on the lower side of the rotating mechanism, aprinting head is arranged on the angle adjusting mechanism, and a workbench is arranged below the printing head. Autorotation and angle adjustment of the printing head are achieved, complex productscan be processed, the structure is simple, and cost is low.

Description

technical field [0001] The invention belongs to the technical field of 3D printers, and in particular relates to an adjustment device for 3D printers. Background technique [0002] 3D printing is a kind of rapid prototyping technology, also known as additive manufacturing. It is a technology based on digital model files and using bondable materials such as powdered metal or plastic to construct objects by layer-by-layer printing. . 3D printing is usually achieved using digital technology material printers. It is often used to make models in the fields of mold manufacturing and industrial design, and is gradually used in the direct manufacture of some products. There are already parts printed using this technology. [0003] 3D printing sometimes needs to print parts with complex structures. At present, the print head of ordinary 3D printers is fixed on the cross arm of the printer, and the angle cannot be adjusted. Products with complex printing structures and large angle c...

Problems solved by technology

[0004] The purpose of the present invention is to provide an adjustment device for 3D printers to solve the problem that the current common 3D printer print head is fixed on the cross arm of the printer, the angle cannot be adjusted, the printing structure is complicated, and the angle changes greatly. Products usually need to be processed on five-axis printers, but five-axis printers are expensive and troublesome to operate, which is a problem that some small and medium-sized enterprises cannot afford
