split nozzle

Abstract

The present invention discloses a split nozzle head, comprising a feeder, a wire feed tube, and a movable nozzle head, the feeder and movable nozzle head being connected by means of the wire feed tube; the movable nozzle head comprises a cavity, a heat-dissipating tab, a thermocouple, and a nozzle; the lower end of the cavity is fixedly connected to the nozzle; the center of the outer side of the cavity is fixedly provided with the heat-dissipating tab; the thermocouple is disposed between the outer side of the cavity, the heat-dissipating tab, and the nozzle, and the thermocouple is fixedly connected to the cavity. The split nozzle head structure of the present invention functionally divides a 3D printing nozzle head device into a feeder, a movable nozzle head, and a wire feed tube; in contrast to the nozzle heads of the prior art, the weight of the parts which move during operation of the nozzle head is reduced, improving the printing speed of a 3D printer; furthermore, the load inertia of the moving parts is reduced due to the reduction in weight of the moving parts, causing the time delay of the moving components when changing direction to be reduced, thus improving printing accuracy.

Description

technical field [0001] The invention relates to a 3D printer accessory, in particular to a split nozzle for 3D printing. Background technique [0002] 3D printing is a kind of rapid prototyping technology. It is a technology based on digital model files and using bondable materials such as powdered metal or plastic to construct objects by layer-by-layer printing. [0003] During the working process of the 3D printer, its load is mainly the nozzle. The nozzle is an important part of the 3D printing equipment. The nozzle realizes the functions of feeding, melting and extruding the printing material. [0004] The Chinese patent publication number is CN103448246A, and the invention name is "integrated 3D printer extrusion nozzle", such as figure 1 As shown, the following content is disclosed: the integrated 3D printer extrusion nozzle includes an extrusion material tube, a fixed bracket, a nozzle, a heating module and a printed circuit board. Wherein, the fixed bracket is sle...

AI Technical Summary

Problems solved by technology

[0005] It can be clearly seen from the above disclosure that due to the need to realize multiple functions, the structure of the existing nozzles has always been relatively complicated, with different functional parts, including the material feeding part, heating and melting part, and material extrusion part; Moreover, the three parts of the existing 3D printer can only work well together if they are tightly connected. However, such a nozzle has a relatively large weight, and under the same conditions, the heavier nozzle will inevitably be reduced to the movement of the nozzle. speed, slow down the printing speed, and the movement inertia of the heavy nozzle is also relatively large, too much inertia will affect the accuracy of the 3D printer
