Description

Technical Field

[0001] This application relates to the technical field of sliding doors, and in particular to a sliding door device and a 3D printer. Background Technology

[0002] A 3D metal printer is a scientific instrument used in basic sciences of physics, engineering and technology, and mechanical engineering. It uses laser melting technology to melt metal powder to form functional solid parts. It can be used to print high-throughput metal materials. It is a fully digital rapid prototyping manufacturing process that directly produces high-density metal parts based on the interface data of each layer in 3D CAD. The thickness of the molten metal layer ranges from 20 micrometers to 100 micrometers, enabling rapid metal prototyping.

[0003] When a 3D printer manufactures parts, metal powder is placed in the forming cylinder of the forming chamber. A laser melting device is positioned on the forming chamber and aims at the metal powder in the forming cylinder to melt it with a laser. The metal then solidifies and forms a shape. The forming chamber has a hinged door that is closed during metal powder processing. After the metal is formed, the door is manually opened to remove the formed metal. However, manually opening the door is time-consuming, labor-intensive, inconvenient, and inefficient. Utility Model Content

[0004] To facilitate the operation of opening and closing doors, save time and effort, and improve efficiency, this application provides a sliding door device and a 3D printer.

[0005] Firstly, the sliding door device provided in this application adopts the following technical solution:

[0006] A sliding door device includes a mounting frame, a mounting plate, a sliding door body, and connecting parts;

[0007] The mounting frame is fixedly mounted on the forming chamber that is used in conjunction with the sliding door device, and the opening at one end of the mounting frame is directly opposite the opening of the forming chamber; the sliding door body is slidably mounted on the side of the mounting frame away from the forming chamber.

The sliding door body is connected to the conveyor belt through a connector, and the sliding door body can move with the conveyor belt to block or open the opening of the molding chamber.

[0009] By adopting the above technical solution, the sliding door in this application is an opening and closing door. When the opening and closing door needs to be opened or closed, the conveyor belt is started. Under the action of the connecting parts, the conveyor belt drives the sliding door body to move, thereby realizing the opening and closing of the opening and closing door. The operation is simple, saves time and effort, and helps to improve efficiency.

[0010] Optionally, the connector is a connecting plate, which is bent to form a connecting part. The connecting part is fixedly connected to the top surface of the sliding door body, and the end of the connecting plate away from the connecting part is connected to the conveyor belt.

[0011] By adopting the above technical solution, the connecting plate has a simple structure, and the connecting plate can be easily connected to the sliding door body after bending, which facilitates the connection between the sliding door body and the conveyor belt.
