Technical Field

The present invention relates to a printing output device, and more particularly, to a coloring mechanism, an output device, a writing pen, and a working method used in a printing output device.

Background

Three-dimensional or two-dimensional output devices, such as 2D or 3D printers, 2D or 3D writing pens, etc., are now in widespread use. For example, the 3D writing pen sends the molten material to a preset point through the writing head for writing, the output path is controlled, the writing work of the 3D writing pen is realized, or the 3D writing pen is used for completing the article to be manufactured through manual control. The 3D writing pen utilizes a melting material such as thermoplastic resin and low-melting-point metal, and the melting material is heated and melted at the writing head, so that different shapes can be manufactured. As shown in figure 1, the output end of the writing pen in the prior art comprises a molten material (1a), the molten material is colored by a coloring mechanism (1b) through a flow channel, the molten material is heated and melted by a heating mechanism (1c) in a melting cavity, the melted molten material is output through a pen point, and the diameter of a channel (1e) of the pen point can be set according to the type of the writing pen. As can be seen from fig. 1, in the prior art, the coloring of the writing pen is single, when the color needs to be changed, the color of the coloring mechanism around the molten material (1a) needs to be changed, and each changing step is complicated; or different colors are filled in the pigment cavities, and the colors are colored in a spraying mode, but the coloring cost is high, and in order to realize the output of different colors of the output equipment, the molten material needs to be colored before being heated and melted, but the color of the existing output equipment is easy to be dragged due to the original pigment residue when the color is changed.
