3D printing material spraying device and using method thereof

Abstract

The invention discloses a 3D printing material spraying device and a using method thereof. The 3D printing material spraying device comprises a spraying body, wherein the spraying body comprises a moving assembly, a rotating assembly and an adjusting assembly which are arranged inside the spraying body; the rotating assembly comprises a fixed plate, a second motor arranged on the bottom wall of the fixed plate, an air cylinder arranged on the top wall of a top plate, a cylinder shaft arranged on the air cylinder and a connecting rod arranged on the outer circumferential wall of the cylinder shaft; the rotating assembly comprises a venturi tube and a side seat arranged on the side wall of the venturi tube; and the adjusting assembly comprises an adjusting seat rotationally connected with the second motor and a sliding drawer arranged on the outer circumferential wall of the adjusting seat. The invention particularly relates to the technical field of 3D printing material spraying devices. According to the 3D printing material spraying device and the using method thereof, the venturi tube which is annularly distributed is arranged, when materials need to be switched by the device, on one hand, the position of the venturi tube is adjusted through the adjusting seat, on the other hand, the venturi tube is driven to move to the lower part of a connecting cylinder through the connecting rod, and then the rapid switching function of the device can be carried out.

Description

technical field [0001] The invention belongs to the technical field of 3D printing material spraying devices, and in particular relates to a 3D printing material spraying device and a use method thereof. Background technique [0002] 3D printing is a kind of rapid prototyping technology, also known as additive manufacturing. 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] Due to the lack of multi-pipe fast switching equipment of the printing head in the existing 3D printing material spraying device, in order to avoid material pollution when switching materials in 3D printing, the 3D printing equipment must wait for the material at the nozzle to be completely output before switching. It causes waste of materials, and also reduces the working efficiency of the equipment. What's more serious is that the equipment cannot perform complex and fast switching m...

Problems solved by technology

[0003] Due to the lack of multi-pipe fast switching equipment of the printing head in the existing 3D printing material spraying device, in order to avoid material pollution when switching materials in 3D printing, the 3D printing equipment must wait for the material at the nozzle to be completely output before switching. It causes material waste and reduces the working efficiency of the equipment. What's more serious is that the equipment cannot perform complicated and fast switching materials, and the product manufacturing capacity is low.
