3D printing machine for manufacturing hollow rubber tires

Abstract

The invention relates to a 3D printing machine for manufacturing hollow rubber tires, and belongs to the field of 3D printing technologies. A movable platform (3) is arranged in the printing machine, a horizontal X-direction screw (4) is arranged below the movable platform (3), and a spraying nozzle (5) is arranged on the horizontal X-direction screw (4) and can move on the horizontal X-direction screw (4); a rotation driving device (12) is further arranged on the printing machine, a rotating body (11) capable of rotating around the horizontal axis is arranged on the rotation driving device (12), and a side ring (14) is arranged on the outer side of the rotating body (11); and the spraying nozzle (5) is used for printing the hollow tires on the side ring (14). The 3D printing machine for manufacturing the hollow rubber tires has the beneficial effects of being good in product molding, high in machining accuracy and high in manufacturing speed.

Description

technical field [0001] The invention relates to a 3D printer for manufacturing hollow rubber tires, belonging to the technical field of 3D printing. Background technique [0002] 3D printing technology (3D printing), which is a kind of rapid prototyping technology, is a technology based on digital model files, using bondable materials such as powdered metal or plastic, to construct objects by layer-by-layer printing. In the past, it was often used to make models in the fields of mold manufacturing and industrial design, and is now gradually being used in the direct manufacture of some products. In particular, some high-value applications (such as hip joints or teeth, or some aircraft parts) already have parts printed using this technology. 3D printing, like laser forming technology, uses layered processing and superimposed molding to complete 3D solid printing. The printing process of each layer is divided into two steps. First, a layer of special glue is sprayed on the ...
