3D printer spraying head device

Abstract

The invention discloses a 3D printer spraying head device. The device comprises a supporting plate, the bottom of the supporting plate is fixedly provided with a sliding rail used for sliding, and a fixing block is fixed to the upper portion of the supporting plate. Through a spherical shell and a heating shell, air generated by an air compressor passes through an annular partition board in the spherical shell to enable a nozzle to generate a pressure, printing ink spraying continuity is ensured, annular heating wires arranged outside a material storage chamber and an inner cavity in the annular shell heat printing raw materials, the printing raw materials are in the molten state all the time, the smooth degree of wires flowing out of the nozzle and the printing model precision are improved, a heat preservation heat isolation layer arranged between the annular shell and the heating shell can ensure that heat generated by the annular heating wires is not diffused out, outward radiationof heat is avoided, gas passing through the interior of a fixed pipeline is diffused to the high temperature through a gas dividing pipe and a diffuser, and the cooling effect is achieved; the problemthat due to the too high temperature of the nozzle, other components are molten and burnt is solved, and running stability of a 3D printer is ensured.

Description

technical field [0001] The invention relates to the field of medical supplies, in particular to a 3D printer nozzle device. Background technique [0002] 3D printers are becoming more and more common in our lives, and are widely used in various fields. The working principle of existing 3D printers is to roll the raw materials on the material tray, and the raw materials are directly drawn from the material tray and introduced into the nozzle, and then processed Heating and other follow-up operations; however, existing 3D printers cannot guarantee that raw materials will enter the nozzle smoothly, and during the heating process of the nozzles of 3D printers, they will radiate to external heat sources, which will affect the normal operation of other equipment. When the stress-generating device is damaged, printing cannot continue, compromising the integrity of the print. Contents of the invention [0003] In order to solve the above existing problems, the present invention p...
