Problems solved by technology

[0002] Existing 3D printers can generally only print materials of one color. When multi-color printing is performed, printers with multiple nozzles are usually required, so people have invented color-mixing printers, and the mixing device is an important device in the color-mixing printer. However, with the continuous development of science and technology, people's requirements for mixing devices are constantly improving, resulting in the existing mixing devices that cannot meet people's requirements.
[0003] There are certain disadvantages in the use of the existing mixing device. First of all, when the existing mixing device is used, the temperature at one end of the throat is high, which will easily cause material expansion and affect the quality of the throat. Moreover, the existing mixing device The mixing effect of the device is not good, and the color mixing is uneven, which does not meet people's requirements. Therefore, we propose a new type of mixing device

Abstract

The invention discloses a novel material mixing device comprising a material mixing device main body, a two-way heat dissipation device, a heating block, a nozzle and a two-way connecting device. Thetwo-way heat dissipation device is fixedly connected with the outside surface of the material mixing device main body by bolts, and the two-way connecting device is fixedly connected with the outsidesurface of the lower end of the material mixing device main body by bolts; and the two-way connecting device is welded with the middle position of the outside surface of the upper end of the heating block. According to the novel material mixing device stated in the invention, firstly, pigments can be preheated, and the accident caused by high temperature expansion of the pigments in a throat is avoided; the service life of the throat is prolonged, and two or more kinds of pigments can be stirred between two groups of agitators repeatedly; the mixing effect of the pigments is improved, and finally the pigments sprayed out from the nozzle are more uniform; the situation that the pigments accumulate or are missing is avoided; and the pigments can be prevented from being stuck at the nozzle position, and the novel material mixing device has better application prospects.
