Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of printer auxiliary feeding, in particular to an auxiliary device for a printer. Background Art
[0002] 3D printing is a type of rapid prototyping technology. It is a technology that uses digital model files as the basis and uses powdered metal or plastic and other bondable materials to construct objects by printing layer by layer. 3D printing is usually achieved using digital technology material printers and is often used in mold manufacturing, industrial design and other fields.
[0003] Since 3D printers may require different wires when printing, and the diameters of different printer wires are not necessarily the same, traditional 3D printers cannot feed printer wires of different diameters, and often need to be disassembled and replaced with printer materials of different diameters, which reduces applicability. Therefore, we propose an auxiliary device for the printer. Utility Model Content
[0004] The purpose of the utility model is to provide an auxiliary device for a printer, by setting a sliding plate 1 and a driving wheel, starting the cylinder output end to push toward the back, so that the sliding block slides toward the back inside the sliding fixed plate, driving the left rack at the bottom of the sliding plate 1 to move toward the back, driving the gear 3 to rotate to move the rack in the opposite direction, so that the sliding plate 1 and the sliding plate 2 can be brought close to each other to clamp the material to be transported, and then the gear 1 at the bottom of the motor 2 is started to drive the gear 2 to rotate forward to transport the material to the right side. The 3D printer can replace materials of different diameters without disassembly, thereby improving the applicability of the printer.
