3D printing spray head for printing clothes

Abstract

The invention discloses a 3D printing spray head for printing clothes. The 3D printing spray head comprises a spray head body, wherein the spray head body comprises a spray tube with an opening in thelower end and a spray nozzle connected to the lower end of the spray tube; the top of the spray tube is fixedly connected with a transverse plate through a bracket; a motor with a downward output shaft is fixedly mounted on the bottom center of the transverse plate; the lower end of the output shaft of the motor is fixedly connected with a rotary shaft; a through hole is formed in the top centerof the spray tube; a cam is fixedly arranged on the outer side of the upper part of the rotary shaft in a sleeving manner; and a plurality of first cutting blades are vertically, uniformly and fixedlymounted on the outer side wall of a circular truncated cone-shaped barrel body. According to the 3D printing spray head disclosed by the invention, automatic unloading of a solid-state wire is realized through an L-shaped plate; the rotary shaft drives the first cutting blades to rotate to be matched with second cutting blades to gradually cut up the cut solid-state wire, so that the solid-statewire is quickly molten while passing through a heating device; and the rotary shaft drives auger blades to rotate to achieve the effect of outwards extruding the molten wire. The 3D printing spray head increases the melting speed and the curing speed of the solid-state wire, so that the working efficiency is improved.

Description

technical field [0001] The invention belongs to the field of 3D printing nozzles, in particular to a 3D printing nozzle for printing clothing. Background technique [0002] With the increasing progress of 3D printing technology, 3D printing technology has gradually entered the clothing market. The 3D printing of clothing includes the overall printing of finished clothing, printing of clothing components, printing of accessories on clothing, etc., due to the principle of additive manufacturing of 3D printing Compared with today's subtractive manufacturing of clothing, it will not cause waste of raw materials, so it has a good application prospect. The materials for 3D printing are roughly divided into solid and liquid. Medium-extrusion is used for stacking, and liquid materials are formed by ultraviolet light solidification. The existing solid wires are generally pushed into the high-temperature cavity by rollers, and after melting a section, the subsequent wires continue to ...

[0002] With the increasing progress of 3D printing technology, 3D printing technology has gradually entered the clothing market. The 3D printing of clothing includes the overall printing of finished clothing, printing of clothing components, printing of accessories on clothing, etc., due to the principle of additive manufacturing of 3D printing Compared with today's subtractive manufacturing of clothing, it will not cause waste of raw materials, so it has a good application prospect. The materials for 3D printing are roughly divided into solid and liquid. Medium-extrusion is used for stacking, and liquid materials are formed by ultraviolet light solidification. The existing solid wires are generally pushed into the high-temperature cavity by rollers, and after melting a section, the subsequent wires continue to be pushed forward. The slow speed makes the work efficiency low, and it will cause the following wire to soften in advance and it is difficult to push the material in the molten state, and the partially melted and partially solid wire is likely to cause nozzle blockage. A 3D printing nozzle is designed to solve the above problems.
