Three-dimensional printer integrated double extruder heads with double cooling air openings

Abstract

The invention relates to the technical field of three-dimensional printers, in particular to three-dimensional printer integrated double extruder heads with double cooling air openings. The three-dimensional printer integrated double extruder heads are characterized by comprising a shell; the front side face of the shell is provided with a left inwards-concave groove and a right inwards-concave groove, and one groove is opened on one side wall of the shell to form an air outlet; a material extrusion motor shaft hole is formed in the position, corresponding to each groove, of the back face of the shell, and a downwards-protruding wire feeding pipe is integrally arranged on the upper wall of each groove; the top end of a wire feeding hole way of each wire feeding pipe is located on the top face of the shell, and an outlet of the wire feeding hole way of each wire feeding pipe is located at the bottom end of the wire feeding pipe; a choke connecting hole is formed in the position, corresponding to the lower portion of the wire feeding pipe, of the lower wall of each groove; a bearing fixing hole pipe used for being connected with an extruder U-shaped wheel is further arranged at the position, located in each groove, on the back face of the shell; and a choke radiating flow guide air opening is further arranged in the lower wall of the groove without the air outlet. Compared with the prior art, double wire feeding extruders are provided; and in addition, accessories are simplified, installation is more convenient, and functions are more.

Description

technical field [0001] The invention relates to the technical field of 3D printers, in particular to a 3D printer integrated double extruder head with dual cooling air outlets. Background technique [0002] The current dual-extruder 3D printers all use two sets of extruder heads, two sets of extruder radiators and at least one set of model cooling blowers. There are many accessories, large volume, cumbersome operation, and complicated maintenance. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies of the prior art. Two sets of motors can be assembled on one extruder head, and two sets of radiators and at least one set of printing model blowers are simplified, while the function of the heat dissipation air outlet of the throat is increased. [0004] To achieve the above purpose, a 3D printer integrated double extrusion head with dual cooling air outlets is designed. And one of the grooves is opened on the side wall of th...
