Consumable fixing device for 3D printing equipment

Abstract

The invention belongs to the technical field of 3D printing, and particularly relates to a consumable fixing device for 3D printing equipment. The device comprises a mounting seat, a containing groove is formed in the top surface of the mounting seat, a hemispherical block is mounted in the containing groove, and a connecting column is mounted on the surface of the hemispherical block; and a plurality of supporting mechanisms are installed on the hemispherical block around the connecting column, a threaded sleeve is installed on the connecting column, and a sealing piece is installed on the bottom face of the threaded sleeve. A fixing mechanism is mounted on the bottom surface of the mounting seat, a [-shaped frame is mounted on the top surface of the connecting column, a fixing shaft is mounted between two vertical sections of the [-shaped frame, a winding drum is mounted on the fixing shaft, and an annular end plate is mounted at the end of the winding drum; an elastic telescopic block is mounted on the horizontal section of the [-shaped frame, and an arc-shaped block is mounted at the end part of the elastic telescopic block; the device can be stably connected to 3D printing equipment in different shapes, and stable supply of consumables is guaranteed; and the condition that the consumables rub with other parts in the printing equipment before entering a printing head can be avoided, so that the loss of the consumables is reduced.

Description

technical field [0001] The invention belongs to the technical field of 3D printing, and in particular relates to a consumable fixing device used in 3D printing equipment. 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 uses adhesive materials to construct objects by layer-by-layer printing; 3D printing usually uses digital technology. Material printing equipment to achieve, 3D printing commonly used consumables include nylon glass fiber, durable nylon material, gypsum material, aluminum material and rubber materials; 3D printing consumables are usually flexible wires, which are wound into The bundle then mounts the fixture to the printing device, which automatically pulls the coiled wire out of the fixture as the printing device works.

Problems solved by technology

[0003] The existing 3D printing equipment consumable fixing device has the following problems in the actual use process: different 3D printing equipment has different shapes, and the consumable fixing device is difficult to be firmly connected to the 3D printing device, resulting in unstable supply of consumables during the printing process; and Due to the irregular shape of the surface of the 3D printing equipment, the consumables between the consumables fixing device and the print head are prone to friction with the 3D printing equipment during the process of bypassing other parts on the printing device, resulting in loss of consumables before printing
