Portable rack for 3D printer

Abstract

The invention relates to a portable rack for a 3D printer. The portable rack for the 3D printer comprises a cover assembly, fixing legs, an upper roller, a material tray, a connecting rod, a lower roller, a discharging bottom plate, a fixing nut, a cover plate frame, a fixing rod, a roller wall, rollers and a rotating shaft. The beneficial effects of the portable rack for a 3D printer are that thecover assembly is detachably and movably connected with the cover plate frame, so that the cover assembly is opened when loading the material tray to facilitate loading the material tray; the fixingrod is slidably connected with the connecting rod, so that the three rollers are adjusted better to fix the material tray; the discharging bottom plate is rotatably connected with the connecting rod and the position of the discharging bottom plate can be fixed, so that different height requirements of discharging are met; eight rollers in total are distributed uniformly on the four vertices at both sides of the rotating shaft, so that the rollers rotate more stably and are not prone to idle; and the roller wall is made of specially-made smooth materials, so that the friction between the material tray and the three rollers is to be as small as possible.

Description

technical field [0001] The invention relates to a portable material rack, specifically a portable material rack for a 3D printer, and belongs to the technical field of 3D printing devices. Background technique [0002] 3D Printers (3D Printers) for short (3DP) is a magical printer designed by an inventor named Enrico Dini, which can not only "print" a complete building, but even Print the shape of any desired item in the spaceship for the astronauts. But what 3D prints out is the model of the object, not the function of the object. [0003] The current FDM 3D printer wire material disk on the market does not rotate concentrically during the printing process, resulting in excessive and disproportionate torque, which exceeds the tensile force that the wire can withstand, so many 3D printers on the market have problems during the printing process.

Problems solved by technology

But what 3D prints out is the model of the object, and the function of the object cannot be printed out.

[0003] The current FDM 3D printer wire material disk on the market does not rotate concentrically during the printing process, resulting in excessive and disproportionate torque, which exceeds the tensile force that the wire can withstand, so many 3D printers on the market have problems during the printing process. Material breakage phenomenon, these wire material tray holders have great disadvantages: for example, it is inconvenient to install the wire material tray, even if the tray is installed correctly, because the tray rotation is not concentric, the feeding motor needs to provide a large torque and the friction that drives the wire forward The wheel is seriously worn, and even the material is broken, which seriously affects the printing quality and the working efficiency of the printer.
