Description

Technical Field

[0001] The utility model belongs to the technical field of automatic paper sticking, and in particular relates to a paper sticking device for automatically fixing line ends of 3D printing materials. 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. Currently, 3D printing usually feeds thermoplastic materials, such as wax, ABS, nylon, etc., in the form of filaments. The material is heated to a molten state by the heating module in the printer head, and then the nozzle moves along the cross-sectional contour and filling trajectory of the part to extrude the molten material. The material solidifies rapidly and condenses with the surrounding material.

[0003] Existing 3D printing uses filamentary materials in rolls as consumables. During the winding process of the 3D printing wire, the winding lengths are not the same, which easily leads to scattering, crosstalk and entanglement, making the wire reel very inconvenient to use. The wire end position of the 3D printing wire is fixed manually, which increases the labor intensity of the workers. Utility Model Content
