A molding cylinder for a 3d printer

Abstract

The invention relates to a molding cylinder of a 3D printer, which includes a cylinder body, a frame, an elastic mechanism, a connecting mechanism and a lifting mechanism; the cylinder body is placed in the frame, and the frame is connected to the elastic mechanism, The cylinder body is supported in motion, the cylinder body is connected with the connecting mechanism, and the lifting mechanism drives the connecting mechanism to move, and then drives the cylinder body to move. The connection mechanism of the present invention is automatically disengaged from the piston of the cylinder body, and the elastic mechanism keeps the upper edge of the cylinder body in close contact with the substrate, and the cylinder body can be taken out separately for external heat preservation, without affecting the continuous printing and use of the equipment. In addition, the molding cylinder of the 3D printer of the present invention can be placed in another oven to slowly cool down, so as to ensure that the molded parts are free from temperature effects, and the 3D printing machine does not cause waste.

Description

technical field [0001] The invention belongs to the technical field of 3D printers, in particular to a molding cylinder of a 3D printer. Background technique [0002] Materials are widely used, and the requirements for 3D printing molding cylinders are getting higher and higher. Some materials need to be kept warm after printing. If they are kept warm in a 3D printer, the machine will be wasted. The cylinder can be taken out flexibly, and the piston and lifting mechanism can be disengaged automatically without much intervention. [0003] In the prior art, the power mechanism and the forming cylinder are integrally formed, which makes the forming cylinder bulky and heavy. On the other hand, the power and guide rail screw are often heated, resulting in thermal deformation and reduced precision. This just requires separate molding cylinder to break away from power mechanism, and molding cylinder can take out mechanism independently. Contents of the invention [0004] Aiming...

[0002] Materials are widely used, and the requirements for 3D printing molding cylinders are getting higher and higher. Some materials need to be kept warm after printing. If they are kept warm in a 3D printer, the machine will be wasted. The cylinder can be taken out flexibly, and the piston and lifting mechanism can be disengaged automatically without too much intervention

[0003] In the prior art, the power mechanism and the forming cylinder are integrated into one structure, resulting in a bulky and bulky forming cylinder. On the other hand, the power and guide rail screw are often heated, resulting in thermal deformation and reduced precision.
