Description

Alloy type 3D is raw material mixing device for printer

Technical Field

The invention belongs to the technical field of printer manufacturing, and particularly relates to a raw material stirring device for an alloy type 3D printer.

Background

A 3D printer is a machine that creates real physical objects based on specialized computer files in an additive creation, and thus the process is referred to as "additive manufacturing. The method comprises the following basic steps: the method comprises the steps of establishing a 3D model by using a computer, slicing the 3D model, dividing the 3D model into hundreds of thin layers, and finally printing the thin layers layer by using a 3D printer until the thin layers are overlapped to form an entity.

Compared to conventional manufacturing techniques, 3D printing techniques have several significant advantages: no mechanical processing or any die is needed, so that the manufacturing time and the production cost are greatly reduced; due to the characteristics of layer-by-layer processing and cumulative molding, the manufacturing is hardly limited by the structural complexity; the model design is very simple and can be changed at any time according to the personalized requirements of the user.

The raw materials of the 3D printer are basically classified into three types, i.e., plastic, photosensitive resin, and alloy, wherein the alloy is adopted by more and more manufacturers due to its characteristics of durability, corrosion resistance, and the like. When the alloy type 3D printer is manufactured, a plurality of raw materials mainly comprising metal powder are firstly mixed and stirred, and then hot-melted and stacked to form a final finished product section.

Because special reasons such as storage environment, the condition of caking often appears in the raw materials, and traditional agitating unit adopts the large leaf stirring leaf to carry out revolution or rotation along certain axis usually, and this just causes stirring leaf and raw materials contact surface limited, leads to stirring quality not good to can't effectively break up the raw materials of caking, this raw materials that just leads to the caking can't stir and open, leads to stirring inhomogeneous.

The stirring blade of the traditional stirring device is usually integrated with a transmission mechanism, so that the traditional stirring device is very inconvenient to disassemble and assemble and is not beneficial to later-stage maintenance.

The raw materials need to be preserved for a certain time after the stirring is finished, but the traditional stirring device does not have preservation conditions, and the phenomenon that the raw materials are damped and agglomerated is often caused.
