Embodiment 1

[0034] figure 1 with figure 2 The 3D printing nozzle 100 provided in this embodiment is shown, including an upper nozzle 101, a lower nozzle 102, and a nozzle 103. The upper nozzle 101 is provided with a cooling chamber 104, and the cooling chamber 104 is provided with four feed pipes 105 and used for Feed pipe 105 is cooled fan (figure not shown), and bottom shower head 102 comprises four heating pipes 106 and four heating bodies 107, and each heating body 107 is arranged around every heating pipe 106 respectively, and four heating pipes 106 One end is respectively connected with the four feed pipes 105 , and the other ends of the four heating pipes 106 are all connected with the nozzle 103 .

[0035] Wherein, the upper shower head 101 is fixedly connected with the lower shower head 102 , and the nozzle 103 is detachably connected with the heating pipe 106 of the lower shower head 102 . The detachable connection enables the nozzle 103 to be replaced in case of damage witho...

Embodiment 2

[0047] On the basis of embodiment one, image 3 The 3D printing nozzle 200 provided in this embodiment is shown, and the 3D printing nozzle 200 also includes a perforating device 201 for dredging the connection between the feed pipe 105 and the heating pipe 106. The perforating device 201 includes a sliding rod 202, a spring 203 and a perforating The needle 204, the perforating needle 204 is connected with the sliding rod 202 through the spring 203, and the sliding rod 202 is slidably connected with the upper nozzle 101. If affected by the heat transfer of the heating pipe 106 , there is a blockage at the connection between the feed pipe 105 and the heating pipe 106 , and the perforating device 201 can be used to complete the dredging.

[0048] In this embodiment, the perforating device 201 also includes an inner cylinder and an outer cylinder, the inner cylinder is sleeved in the outer cylinder, and the top of the inner cylinder is connected to the top of the outer cylinder t...

Abstract

The invention relates to the technical field of 3D printing and provides a 3D printing spray head. The 3D printing spray head comprises an upper spray head body, a lower spray head body and a spray nozzle. A cooling cavity is formed in the upper spray head body. The cooling cavity is internally provided with four feeding pipes and a fan used for cooling the feeding pipes. The lower spray head body comprises four heating pipes and four heating bodies. Each heating body is arranged around one heating pipe. The ends of the four heating pipes are connected with the four feeding pipes respectively. The other ends of the four heating pipes are connected with the spray nozzle. The 3D printing spray head can be used for printing four materials, and if the 3D printing spray head is only used for printing one material, the printing speed can be increased.

Description

technical field [0001] The invention relates to the technical field of 3D printing, in particular to a 3D printing nozzle. Background technique [0002] 3D printing is a technology based on digital model files, using adhesive materials such as plastics, to construct objects by layer-by-layer printing. With the advantages of simple process, no need for mechanical processing or molds, effective shortening of product production cycle, low operation and maintenance costs, 3D printing technology is gradually being widely used in primary model manufacturing in mold manufacturing, industrial design and other industrial fields, some Direct manufacturing of products; it is also gradually being applied to the realization of DIY personal ideas, as well as the reproduction of toys. [0003] The realization of 3D printing technology depends on 3D printers. The technical content of existing 3D printers mainly includes: input software data commands to control 3D printers, heat and melt fi...
