Abstract

The invention discloses a double-nozzle device based on an FDM technology. The double-nozzle device is connected with an extruding device through a material sending pipe and comprises a transmission device, an upper aluminum block, a lower aluminum block, a radiating device, two nozzles and two feeding pipes, all of which are connected in sequence through hand screwing screws. The feeding pipes between the upper aluminum block and the lower aluminum block are sequentially sleeved with springs, isolation blocks and connecting blocks. The radiating device comprises two radiating fans and a ventilating block. The two radiating fans are arranged on the two sides of the nozzle device through the connecting blocks. The ventilating block is located between the two radiating fans. One ends of the two feeding pipes communicate with the extruding device through the material sending pipe, and the other ends of the two feeding pipes sequentially penetrate the transmission device, the upper aluminum block and the lower aluminum block and then communicate with the nozzles, and heating blocks are arranged at the connecting positions of the feeding pipes and the nozzles. According to the double-nozzle device based on the FDM technology, the double-nozzle structure is adopted, so that bicolor printing is supported; and in addition, the efficient radiating device is adopted, material blocking can be effectively prevented, and therefore the printing quality is improved.

Description

[0001] 【Technical field】 [0002] The invention belongs to the field of FDM technology, in particular to a double nozzle device based on FDM technology applied to desktop 3D printing equipment. [0003] 【Background technique】 [0004] FDM technology, fused lamination technology, the abbreviation of Fused Deposition Modeling, can also be called fusion deposition technology, which is a kind of rapid prototyping technology. [0005] Rapid prototyping technology, that is, Rapid Prototyping (referred to as RP technology), RP technology is a new technology pioneered by industrialized countries in the late 1980s. Its main technical feature is the rapidity of molding, which can be automatically, quickly and accurately Transforming design ideas into product prototypes with certain functions or directly manufacturing parts, this technology can not only shorten the product development cycle and reduce product development costs, but also play an important role in quickly responding to mark...
