Feeding device for 3D printer

Abstract

The invention discloses a feeding device for a 3D printer. The feeding device comprises a mounting plate, and a mounting base is arranged on the top surface of a shell; a first transmission shaft is movably mounted on the surface of the mounting base through a bearing, and one end of the first transmission shaft is in key connection with a first bevel gear through a key; the motor is installed onthe surface of one side of the shell through a connecting piece cooperatively, and one end of the second transmission shaft penetrates through the surface of the shell through a bearing, and is in keyconnection with a second bevel gear through a key; the first bevel gear is meshed with the second bevel gear, and a limiting mechanism is installed on the bottom surface of the shell; and an output mechanism is arranged at the bottom of the limiting mechanism. According to the feeding device, through optimization of the feeding structure, and additional arrangement of the limiting mechanism cooperated with the output mechanism, heat possibly transmitted is isolated, and a certain supporting effect is provided for consumables in cooperation with guide wheels, so that the quality of the consumables is guaranteed.

Description

technical field [0001] The invention relates to the field of feeding devices, in particular to a feeding device for a 3D printer. 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] Among them, during the loading process of the mechanical arm 3D printer, the material tray is generally used to supply the output part of the printer. The structure is relatively simple, and the heat may radiate to the feeding mechanism due to the continuous heating of the output end, which in turn makes the consumables in the output process. A certain amount of softening occurs in advance, which affects the feeding effect. And the dust in the air may be contaminated during the feeding process, which will adversely affect the subsequent printing work. Con...
