Description

Technical Field

[0001] The utility model relates to the technical field of 3D printers, in particular to a 3D printer wire combing device. Background Art

[0002] 3D printing is usually achieved by using digital technology material printers. It is often used to make models in the fields of mold manufacturing and industrial design, and then gradually used for the direct manufacturing of some products. There are already parts printed using this technology. This technology is used in jewelry, footwear, industrial design, architecture, engineering and construction (AEC), automobiles, aerospace, dental and medical industries, education, geographic information systems, civil engineering, firearms and other fields. The consumables of 3D printers are generally stored in a winding reel. When the 3D printer is working, the material is loaded through the winding reel. In the current technology, the wire on the reel is pulled by the pulling force generated by the working end of the 3D printer. This method is easy to break the wire when the 3D printer is working, which wastes time and also consumes a lot of energy. For example, the existing Chinese utility model patent with patent number CN 211730275 U discloses a wire combing device for a 3D printer. Although the wire combing device solves the above problems, the function of the wire combing device is relatively simple, especially when the pulling range is too large, the wire is still easy to be broken.
