Three-dimensional material adding printer with automatic material guiding function

Abstract

The invention discloses a three-dimensional material adding printer with an automatic material guiding function. The printer comprises a protection box body, wherein the inner cavity of an equipment installation cavity is provided with a driving motor; the front part, which extends out of the protection box body, of the first spindle of the output end of the driving motor is connected with a mainmaterial guiding wheel; the front part, which extends out of the protection box body, of a second spindle is connected with an auxiliary material guiding wheel; the front part, which extends out of the protection box body, of the left end of a third spindle is connected with a main material guiding gear; and the front part, which extends out of the protection box body, of the left end of a fourthspindle is connected with an auxiliary material guiding gear. A long and cylindrical printing raw material enters between the arc-shaped spacing plate of an auxiliary spacing device and the front surface of the protection box body so as to reduce the swinging of the long and cylindrical printing raw material; and the auxiliary material guiding gear and the main material guiding gear are both in contact with the surface of the long and cylindrical printing raw material, and the main material guiding gear cuts one side of the surface of the long and cylindrical printing raw material but does notcut off the printing raw material so as to be favorable for the printing material to be heated and melted after the printing raw material enters the venturi of a spray nozzle.

Description

technical field [0001] The invention relates to the technical field of printers, in particular to a three-dimensional additive printer with an automatic material guiding function. Background technique [0002] 3D additive printer is a kind of accumulative manufacturing technology, that is, a machine of rapid prototyping technology. It is based on a digital model file, using special wax, powdered metal or plastic and other bondable materials to print a layer of Layers of bonding material to create three-dimensional objects. The biggest difference between it and traditional printers is that the "ink" it uses is a real raw material. There are various forms of stacking thin layers, and there are various types of media that can be used for printing, from a variety of plastics to metals, ceramics and rubber. substance. [0003] The printing material needs to be heated and melted, but before the printing starts, the printing material needs to be guided, otherwise it cannot be con...

AI Technical Summary

Problems solved by technology

[0003] The printing material needs to be heated and melted, but before the printing starts, the printing material needs to be guided, otherwise it cannot be continuously supplied to the heating and melting device, which will delay the printing process and affect the printing effect. Do processing so that it cannot be heated and melted quickly in the follow-up, which will affect its melting speed. For this reason, we have introduced a 3D additive printer with automatic material guide function
