[0002] The current fused deposition modeling (FDM) 3D printers mainly rely on wire material trays for feeding and printing; and there are three main types of wire material trays used in the market; the first is a cardboard tray with the disk surface and the shaft tube bonded as a whole; the second is an integral plastic tray with the disk surface and the shaft tube separately injection molded and then spliced ​​and bonded; the third is an offset docking tray with the disk surface and the shaft tube that can be disassembled and assembled; among them, the first cardboard tray and the second plastic tray are usually discarded after the wire is exhausted at the factory because it is inconvenient for users to rewind the wire, resulting in waste; the third offset docking tray, although it can dock and fill 3D printing wire The paper tube can be reused, but the left and right trays are different when docked under the offset docking structure, and two sets of molds are required during manufacturing, which increases the production cost. Moreover, if the left tray is more unqualified, the right tray is missing matching parts, which is easy to cause production waste. In addition, the outer wall of the shaft tube of the current third offset docking tray is relatively smooth, and only the passive rotation when cooperating with the FDM printer's wire drawing action is considered, but the active rotation when the tray driving mechanism actively rotates to feed the wire is not considered. Therefore, the friction between the shaft tube and the paper tube is small, and the shaft tube is prone to slip during active feeding, resulting in poor feeding effect.
