Problems solved by technology

[0004] Fused deposition 3D printers have become the most commonly used 3D printing technology because of their low cost, small size, no pollution, and low cost. The wire feeding mechanism of this type of printer is one of its key components; however, FDM feeding The wire mechanism often has problems of insufficient driving force, unstable wire feeding and inconvenient adjustment of the wire feeding device during operation, which affects the molding efficiency and the quality of the molded parts

Abstract

The invention designs a wire feeding mechanism provided with adjustable pressing force and used for a 3D printer. The wire feeding mechanism comprises a rack (2), wherein a motor (1) is arranged at the left side of the rack; a pinion (3) is mounted on the output shaft of the motor; a meshing transmission belt drives a big gear (4) to rotate, a wire feeding drive wheel (5) is mounted on a big gear shaft; the wire feeding drive wheel is fixed to a big gear shaft through a fastening screw (6); the right side of the wire feeding drive wheel is equipped with a wire feeding driven wheel (7) which is pressed on a pressing frame (8); the lower portion of the pressing frame is hinged to the lower end of the right side of the rack through a bolt (15); a stand column (9) is arranged on a baffle plate on the middle of the rack; a mounting hole is formed in the stand column; the left side of a screw (10) is mounted in the mounting hole; the right side of the screw is connected to the upper end of the pressing frame through a screw-up nut (12); and a pressing spring (11) is arranged between the upper end of the pressing frame and the stand column. The wire feeding mechanism has the beneficial effects that the structure is compact, drive force is adjustable, pressing force is conveniently adjusted, and requirements of wires with different diameters can be adapted.

Description

technical field [0001] The invention relates to the technical field of rapid prototyping, in particular to a wire feeding mechanism of a 3D printer with adjustable pressing force. Background technique [0002] 3D printing technology is a kind of additive manufacturing technology. 3D printer is a kind of machine of rapid prototyping technology. It is based on digital model files and uses adhesive materials such as special wax, plastic or powdered metal to print a layer. Layers of adhesive materials to make three-dimensional objects, at this stage 3D printers are used to make products; 3D printing technology has now been used in product prototypes, mold making, art creation, jewelry and other fields, it is used in bioengineering and medicine, architecture, clothing and other fields continue to develop and innovate. [0003] Ordinary 3D printers used in daily life can print flat objects designed by computers. The so-called 3D printers work basically the same as ordinary printe...
