Embodiment Construction

[0017] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0018] see figure 1 , the three-dimensional printing device 1 includes a bottom plate 11 and a forming seat 12 arranged on the bottom plate. Four screw rods 13 extend vertically upward from the bottom plate 11 , and the frame 14 is sleeved on the screw rods 13 and can be linearly fed along the Z direction along the screw rods 13 . A guide rod 15 is further provided on the frame 14, and the guide rod 15 can be linearly fed along the Y direction on the frame 14. The printing head 16 is sleeved on the guide rod 15, and can perform linear feeding along the X direction. Through the control of the 3D printing device 1 , the printing head 16 can be fed in the X, Y, and Z directions, thereby realizing the expected 3D printing.

[0019] see figure 2 and image 3 , the print head 16 has four storage chambers (161, 162, 163, 164), and the storage chambers (4...

Abstract

The invention discloses a printing head. The printing head comprises at least two material storage cavities used for storing printing materials in different colors, a material blending cavity selectively communicated with the at least two material storage cavities, a nozzle communicated with the material blending cavity and used for spraying printing materials, a cleaning cavity adjacent to the material blending cavity and communicated with the material storage cavity, and a switch assembly capable of switching on / off the communication between the material blending cavity and the cleaning cavity. In a printing process of a printing device, one or several materials in different colors can be blended in the material blending cavity of the printing head according to different proportions as required, so that products in rich colors are printed and personalized printing requirements can be well met.

Description

technical field [0001] The invention relates to a printing head, in particular to a printing head in a three-dimensional printing device. Background technique [0002] Currently, commonly used printing devices are designed for the surfaces of various flat materials, such as paper, leather, plastic, glass, metal, etc., and such printing devices have been widely used in office and household purposes. In the usual printing method, on the one hand, the surface of the printed entity is transported relative to the print head (or the print head actually moves, and the printed surface is stationary), and at the same time, the print head scans and moves along the direction perpendicular to the relative transport motion of the printed entity, and performs Print. These printing devices are all applied to flat printing, that is, two-dimensional printing. [0003] For the surface coloring of three-dimensional objects, manual or semi-manual methods are generally used, such as thermal tr...
