Problems solved by technology

[0002]The 3D printers using fused filament lamination molding technology mainly use heat-melting materials to heat and melt, and the melted materials are ejected from the nozzle under the control of the computer. The profile of the section, the material is selectively coated on the workbench, and the rapid cooling port forms a layer of section. After one layer is formed, the workbench is lowered or raised to a height, and then the next layer is formed until the entire solid shape is formed. , due to the problem of uneven thickness of the thermal fuse used in printing, it is easy to have the problem of slippage of the card wire wheel when the three-digit printer is working, which leads to uneven diameter of the thermal fuse sprayed from the nozzle and affects the printing accuracy and quality

Abstract

The invention relates to a synchronous fuse feeding three-dimensional printer, which comprises a frame and a printing mechanism arranged on the frame. The printing mechanism includes a mounting base arranged on the frame, a servo motor arranged on the mounting seat, a fuse block wheel set driven by the servo motor, and a material guide pipe disposed below the fuse block wheel set. The lower end of the material guide pipe is provided with a fuse spitting hole, the inlet end of the material guide pipe is disposed right below the fuse block wheel set, which comprises a first fuse block wheel and a second fuse block wheel, and also includes a synchronous transmission device driven by the servo motor. The synchronous transmission device drives the first fuse block wheel and the second fuse block wheel synchronously. Due to the employment of synchronous driving wheels in the invention, the left fuse block wheel and the right fuse block wheel can roll synchronously, thus increasing the fuse feeding thrust and ensuring reliable fuse feeding. Meanwhile, elasticity is employed to compress thermofuses, thus further reducing the possibility of thermofuse slipping, and improving the printing reliability of the three-dimensional printer.

Description

technical field [0001] The invention relates to the field of three-dimensional printers, in particular to a three-dimensional printer with synchronous wire feeding. Background technique [0002] The 3D printer using the fuse fusion lamination molding technology mainly uses heating and melting materials to heat and melt, and the melted materials are ejected from the nozzle under the control of the computer, and the materials are selectively coated on the workbench according to the outline of the section , the rapid cooling port forms a layer of cross-section. After one layer is formed, the workbench is lowered or raised to a height, and then the next layer is formed until the entire solid shape is formed. Due to the thermal fuse used in printing, there may be problems of uneven thickness. , When the three-digit printer is working, it is easy to have the problem of slippage of the card wire wheel, which leads to the uneven diameter of the thermal fuse sprayed from the nozzle, ...
