Abstract

A 3D printer short-distance feeding combination device of the present invention includes a machine body, a material extrusion system, a material feeding head and a printing nozzle, and the material extrusion system is arranged inside the machine body, including a material extrusion motor, a transmission shaft and an extrusion part, and the output of the material extrusion motor The first transmission gear is installed on the shaft, and the two transmission shafts are respectively arranged above and below the output shaft of the feeding motor. One end of the two transmission shafts is equipped with a second transmission gear meshing with the first transmission gear, and the middle part is equipped with a driving gear. The top and bottom of the extruded part are equipped with driven rollers that rotate with the driving roller. The extruder is equipped with an extrusion hole that penetrates up and down. The extrusion hole is set between the driving roller and the driven roller, and is driven by the extrusion motor. The rotation of the first transmission gear drives the rotation of the two second transmission gears, and then drives the rotation of the two transmission shafts, thereby driving the rotation of the two sets of driving rollers and driven rollers, which can not only realize accurate feeding, but also increase torque and increase extrusion. Machine extrusion power.

Description

technical field [0001] The invention relates to the technical field of 3D printers, in particular to a 3D printer short-distance feeding combination device. Background technique [0002] In recent years, the development of 3D printing technology is in full swing. Among them, fused deposition technology is one of the fastest-growing technologies in 3D printing technology. 3D printers developed based on FDM technology are widely known because of their low manufacturing cost, portable equipment, and low requirements for the working environment. [0003] In the prior art, the extruder of the FDM type 3D printer extrudes the material directly by setting the feeding gear on the output shaft of the stepping motor. Extruding with a single feed gear often results in uneven or impossible discharge due to lack of power. Contents of the invention [0004] According to the deficiencies of the prior art, the purpose of the present invention is to provide a 3D printer short-distance fe...
