Tension-adjustable wire feeding mechanism for 3D printer

Abstract

The invention discloses a tension-adjustable wire feeding mechanism for a 3D printer. The tension-adjustable wire feeding mechanism comprises a worktable, a mounting base is connected to the bottom ofthe worktable, and a cleaning transmission device and a moving wire feeding device are mounted at two ends of the worktable respectively. The moving wire feeding device comprises a fixing seat connected to the surface of one end of the worktable, the fixing seat is in hinged connection with a hydraulic rod through a hinge seat, the top end of the hydraulic rod is connected with a moving wire feeding seat, and a wire feeding component is arranged in the moving wire feeding seat. An electric push rod is hinged to the bottom end of the moving wire feeding seat, and the bottom end of the electricpush rod is movably hinged to the fixing seat. A tension mechanism is mounted at the center of the surface of the worktable and positioned between the cleaning transmission device and the moving wirefeeding device, and an emergency clamping mechanism is mounted on one side of the worktable. Wire feeding is realized by the moving wire feeding mechanism which is flexible in adjustment, surface cleaning is realized during material wire guide, printing quality is improved, and great cooling effects and convenience in use are achieved.

Description

technical field [0001] The invention relates to the technical field of 3D printing, in particular to a tension-adjustable wire feeding mechanism for a 3D printer. Background technique [0002] 3D printing is a kind of rapid prototyping technology. 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 usually uses Realized by digital technology material printers, it is often used to manufacture models in mold manufacturing, industrial design and other fields, and is gradually used in the direct manufacture of some products. There are already parts printed using this technology. This technology is used in jewelry. , footwear, industrial design, architecture, engineering and construction, automotive, aerospace, dental and medical industries, education, geographic information systems, civil engineering, firearms, and other fields have applications.

AI Technical Summary

Problems solved by technology

[0007] (1) The general wire feeding device cannot be adjusted when feeding the material wire, resulting in wire feeding only through a fixed angle and height, which is difficult to meet different wire feeding requirements;

[0008] (2) At the same time, during the wire feeding process, due to friction, the surface of the material wire is not only prone to debris, but also prone to heat, resulting in thermal wear of the material wire, and excessive heat generation affects the stable use of the device;

[0009] (3) Moreover, when feeding the wire, the material wire may break suddenly, and the general wire feeding device lacks an emergency clamping device, which cannot deal with emergencies
