  • Patent number: 12139366
    Abstract: Provided are a rotary shaft of a three-dimensional printing filament spool holder, a three-dimensional printing filament spool holder, and a three-dimensional printer, comprising a fixed tube and a sleeve assembly sleeved outside the fixed tube and being capable of rotating relative to the fixed tube. The sleeve assembly is elastically connected to the fixed tube through an elastic member, the relative rotation between the sleeve assembly and the fixed tube causes the elastic member to generate elastic deformation, and the sleeve assembly is configured for being sleeved in a three-dimensional printing filament spool.

  • Publication number: 20230407946
    Abstract: Some embodiments provide a belt tensioning mechanism for a 3D printer and a 3D printer. In those embodiments, the belt tensioning mechanism comprises a base, a driving pulley, at least one timing pulley, a sliding block, a tensioning pulley, a spring. The base is provided with a first sliding groove. The driving pulley and the at least one timing pulley are mounted on the base and are connected in series with each other via a belt. The sliding block is mounted on the base and is capable of sliding along the first sliding groove. The tensioning pulley is mounted on the sliding block and is connected in series with the driving pulley and the at least one timing pulley via the belt so as to tension the belt. The spring is configured to apply an elastic force to the sliding block.

  • Publication number: 20230407947
    Abstract: Various embodiments provide a timing belt tensioner for a 3D printer and the 3D printer. In those embodiments, the timing belt tensioner includes: a mounting frame, an idler and an elastic member, where the idler is connected to the mounting frame, and a timing belt of the 3D printer is wound around the idler, and is configured to drive a movement mechanism of the 3D printer to move on an XY plane; and the elastic member is configured to connect the mounting frame and a base of the 3D printer such that the mounting frame drives the idler to slide to a balance position relative to the base under an elastic force of the elastic member. When at the balance position, a balance is reached between the elastic force of the elastic member and a tensile force of the timing belt acting on the idler.
