Raw material screening device for 3D printing consumable production

Abstract

The invention discloses a raw material screening device for 3D printing consumable production. The device comprises a housing and a first motor. Screening mechanisms are movably mounted on the inner walls of the two sides of the housing through bearings correspondingly. The screening mechanism comprises an upper ring sleeve, a framework and a lower ring sleeve; transmission plates are welded on the surfaces of the upper ring sleeve and the lower ring sleeve which are arranged at one end of the screening mechanism; the output end of the first motor is welded and fixed to the transmission plate;the upper ring sleeve and the lower ring sleeve arranged at the other end of the screening mechanism are movably connected with one end of a feeding cylinder; a feeding mechanism is arranged on the surface of the feeding cylinder; a third motor is installed at one end of the feeding cylinder; and the output end of the third motor is in transmission connection with one end of a spiral feeding rodthrough a shaft coupler. The feeding mechanisms and the screening mechanisms are matched with each other, so that consumable raw materials are continuously scattered and turned over through the spiralfeeding rod in the screening process, and the screening effect is improved through cooperation of the mode.

Description

technical field [0001] The invention belongs to the technical field of screening devices, and in particular relates to a raw material screening device for the production of 3D printing consumables. 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. . 3D printing is usually achieved using digital technology material printers. It is often used to make models in the fields of mold manufacturing and industrial design, and is gradually used in the direct manufacture of some products. There are already parts printed using this technology. The technology has applications in jewelry, footwear, industrial design, architecture, engineering and construction (AEC), automotive, aerospace, dental and medical industries, education, geographic information syste...
