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.
Claims16
A timing belt tensioner for a three-dimensional (3D) printer, the timing belt tensioner comprising:
- a mounting frame;
- an idler pivotally connected to the mounting frame, wherein a timing belt of a 3D printer is wound around the idler and is configured to drive a movement mechanism of the 3D printer to move on a plane;
- and
- an elastic member 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, wherein 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;
- a fastening assembly;
- and, wherein the mounting frame is fastened to the base through the fastening assembly and is at the balance position;
- wherein the fastening assembly comprises at least one third fastener, wherein the mounting frame is provided with at least one elongated hole extending in a direction parallel to a sliding direction of the mounting frame, and each third fastener of the at least one third fastener penetrates through a corresponding elongated hole of the at least one elongated hole and is in threaded connection with the base.
A 3D printer, comprising:
- a movement mechanism;
- the movement mechanism includes at least one of a printing head for ejecting a printing material, a print table for accommodating the printing material;
- a base provided with a timing belt configured to drive the movement mechanism to move on a plane;
- and
- a timing belt tensioner, wherein the timing belt is wound around an idler of the timing belt tensioner, the timing belt tensioner comprises:
- a mounting frame;
- an idler pivotally connected to the mounting frame, wherein a timing belt of a 3D printer is wound around the idler and is configured to drive a movement mechanism of the 3D printer to move on the plane;
- and
- an elastic member 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, wherein 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;
- a fastening assembly;
- and, wherein the mounting frame is fastened to the base through the fastening assembly and is at the balance position;
- wherein the fastening assembly comprises at least one third fastener, wherein the mounting frame is provided with at least one elongated hole extending in a direction parallel to a sliding direction of the mounting frame, and each third fastener of the at least one third fastener penetrates through a corresponding elongated hole of the at least one elongated hole and is in threaded connection with the base.
