Description

Technical Field

[0001] This utility model relates to the field of 3D printing consumable auxiliary devices, and in particular to a material rack structure for printing consumables. Background Technology

[0002] A 3D printer, also known as a three-dimensional printer, is a type of additive manufacturing technology, or rapid prototyping technology. It uses a digital model file as a basis and employs special waxes, powdered metals, or plastics—materials that can be bonded—to create three-dimensional objects by printing layers of these bonding materials. 3D printing filaments are the printing materials used in 3D printing equipment. These filaments are typically supported by a filament support frame located on the outside of the printing equipment. Current filament support frame structures use vertical roller supports, which present the following problems in use:

[0003] 1. The structure is relatively complex. During use, the material tray needs to be installed on the vertical roller support, which is inconvenient. Especially for large-volume printing jobs, the replacement of the material tray takes a lot of time, which in turn affects the normal printing operation of the 3D printing equipment.

[0004] 2. The structure is fixed and cannot be adjusted; the vertical roller support is only suitable for the installation and support of consumable trays with fixed shaft diameter and outer diameter, and its application range is limited. In specific use, it cannot meet the needs of large-volume printing jobs of different types. Summary of the Invention

[0005] To address the problems of existing filament support structures being complex, requiring the material tray to be mounted on a vertical roller support during use, which is inconvenient and time-consuming to replace, thus affecting the normal printing operation of 3D printing equipment, this utility model provides a filament support structure for printing, the specific technical solution of which is as follows:

[0006] A printing consumable rack structure includes a left support part, a right support part, and a connecting slider. The left support part is connected to the right support part via the connecting slider. The left and right support parts have the same structure, each including a first support wheel set, a second support wheel set, and a support base. A first guide groove adapted for mounting the first support wheel set is formed on the upper left side of the support base. The lower side of the first support wheel set is disposed in the first guide groove and slides in contact with the first guide groove.
