Abstract

The invention discloses a printing nozzle. The printing nozzle comprises a cooling pipe, a throat pipe and a nozzle connected in sequence from top to bottom; a heating device is arranged on the throat pipe; the nozzle is an inverted cone vertically arranged; three channels are at least formed in the nozzle; openings of the channels are positioned in the upper surface of the nozzle; the channels at least include fixed holes communicated in sequence from top to bottom and with gradually decreased diameters, first connecting pipes and second connecting pipes; a liquid guide pipe is arranged in the nozzle; one end of the liquid guide pipe is communicated with the multiple second connecting pipes, and the other end is arranged in an outlet of the nozzle and communicated with the outlet of the nozzle; and an adjusting device is arranged on the throat pipe. The nozzle overcomes the problems of incapability of adjusting the types of raw materials due to one channel in the printing nozzle, single printing color and incapability of printing out products formed by multiple color combinations. The printing nozzle can change the colors of the raw materials, has multiple raw material channels, can adjust the types of the printing raw materials, and can print out the products formed by the multiple color combinations.

Description

technical field [0001] The present invention relates to the field of printer components, in particular, to a print nozzle. Background technique [0002] With the development of society, the types of printers are also rich and diverse. Among them, 3D printers are very popular printers at present. It melts solid raw materials and reprints them through nozzles, and then solidifies them to form various designed works. However, in the prior art, there is only one channel inside the nozzle of the printer, and the types of raw materials cannot be adjusted, and the printed color is single, so it is impossible to effectively print products formed by combining multiple colors or mixing colors. [0003] Therefore, it is an urgent problem to be solved in the present invention to provide a printing nozzle that can change the color of the raw material during use, has multiple raw material channels, can adjust the type of printing raw material, and can print products formed by a variety of...
