[0002] 3D printer is a kind of rapid prototyping equipment, which is based on digital model files, uses special wax materials, powdered metal or plastic and other adhesive materials to print layers of adhesive materials to create three-dimensional objects. At present, in the process of using 3D printers, consumables are needed, and common consumables are wound on a winding reel, so the consumable winding reel needs to be installed on the material rack for use.

[0003] The current consumables tray rack generally adopts the method of setting a pulley mechanism at the bottom, such as the patent with application number 2023208017096, in which a rotating pulley is set on the tray bracket. The pulley is a recessed structure that can correspond to the limited position of the tray body of the consumable tray. After the consumable tray is installed, it is pulled by the wire feeder, and the consumable tray and the pulley rotate synchronously to achieve the purpose of continuous wire feeding. Or as in the patent with application number 2018101078618, there is a U-shaped groove on the support seat, and the roller is placed in the U-shaped groove of the two support seats. The consumable tray is sleeved on the roller, and the roller is rotated by the wire feeder to achieve the purpose of continuous wire feeding. However, the above common consumable rack rollers are in contact with the pulley or the base. After the wire feeder is pulled, a large sliding friction force will be generated, and the wire feeding is prone to slippage. Therefore, it is urgent to design a consumables tray rack for 3D printers to solve the above problems. Utility Model Content
