Rack for desktop 3D printer

Abstract

The invention discloses a material rack for a desktop 3D printer, comprising a first casing, the back of the inner wall of the first casing is fixedly connected with an organic base, and the lower surface of the base is fixedly connected with a body of a biaxial motor , and the two output shafts of the double-axis motor are fixedly connected with threaded posts, and the threads of the two threaded posts are opened in opposite directions, and the outer surfaces of the two threaded posts are threaded with threaded caps. This material rack is used for a desktop 3D printer. By setting a double-axis motor, a threaded column, a threaded cap, a first bearing, a first rotating shaft, a slider, a chute, a first through hole and an extrusion block, the two threaded caps pass through two A second connecting plate drives the two extruding blocks close to each other, so that the two extruding blocks can press the bottom frame of the 3D printer, thereby realizing the fixing of the device, so that the device does not need to be fixed with bolts and nuts, and will not Destroying the surface of the 3D printer will not affect the appearance of the 3D printer, and it is easy to disassemble and assemble.

Description

technical field [0001] The invention relates to the technical field of printers, in particular to a material rack for desktop 3D printers. Background technique [0002] 3D printers can not only "print" a complete building, but can even print the shape of any desired item for astronauts in a spaceship. But what 3D prints out is the model of the object, not the function of the object. [0003] At present, desktop 3D printing on the market usually uses an external material rack, and it is troublesome to replace the material tray and bracket. Therefore, people have designed a variety of 3D printer material racks that are easy to replace the material tray. For example, a Chinese patent discloses a material for desktop 3D printers. Rack (Patent No.: CN 206475455U), this patent uses a tilted hanging rod to hang the feed tray, which solves the problem of inconvenient disassembly and assembly of the existing 3D printer. Opening a hole in the frame of the 3D printer will affect the ...

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a material rack for desktop 3D printers, which solves the problem that external material racks are usually used for desktop 3D printing in the market, and it is troublesome to replace the material tray and bracket. Therefore, people have designed many A kind of 3D printer material rack that is convenient for replacing the material tray, for example, a Chinese patent discloses a material rack for desktop 3D printers (patent number: CN206475455U), this patent adopts an inclined hanging rod to hang the material tray, which solves the problem of disassembly and assembly of existing 3D printers. The problem of the inconvenience of the material tray, but the connection method of the patent and the 3D printer is a threaded connection, which needs to open a hole on the frame of the 3D printer, which affects the beauty of the 3D printing, and the hanging rod for hanging the material tray will not rotate, resulting in only Suspend the tray with a certain diameter, if you need to replace the larger tray, you can’t use it, and its practicality is poor
