Description

Technical Field

[0001] This utility model relates to the field of 3D printer technology, and in particular to a bidirectional sand-laying device for a sand mold 3D printer. Background Technology

[0002] A sand mold 3D printer is an industrial printer based on additive manufacturing technology. It uses the principle of layer-by-layer deposition to transform a digital model into an actual sand mold part. This type of printer has a wide range of applications, from simple sand mold parts to complex metal components. With continuous technological advancements, sand mold 3D printers are finding increasingly widespread use in various fields.

[0003] Sand mold 3D printers utilize additive manufacturing technology to build objects by continuously stacking materials. Compared to traditional subtractive manufacturing methods, sand mold 3D printing significantly reduces material waste and can create more complex shapes and structures. Furthermore, sand mold 3D printers offer high production efficiency, drastically shortening manufacturing cycles and reducing production costs.

[0004] Sand mold 3D printers generally use a bidirectional sand laying method. When the laying direction is changed, material splashing is easy to occur, and external impurities and dust can easily mix into the laying area, affecting the quality of the finished product. Therefore, a bidirectional sand laying device for sand mold 3D printers is proposed. Utility Model Content

[0005] The main purpose of this utility model is to provide a bidirectional sand-laying device for a sand mold 3D printer. By setting up a protective side plate, a first movable plate, a second movable plate and a soft connecting plate, the problems in the background art can be effectively solved.

[0006] To achieve the above objectives, this utility model provides a bidirectional sand-laying device for a sand mold 3D printer, including a protective side plate, a movable plate assembly, a pulling assembly, and a flexible connecting plate;

[0007] The protective side plate is installed on one side of the printer nozzle;

[0008] The movable plate assembly includes a first movable plate and a second movable plate. A first gear is provided on one side of the first movable plate, and a second gear is provided on the side of the second movable plate close to the first movable plate. The side of the first movable plate away from the second movable plate is rotatably connected to a protective side plate, and the first gear and the second gear mesh.

[0009] The pulling assembly includes a drive motor and a pull rope. A rotating roller is detachably mounted on the output shaft of the drive motor. One end of the pull rope is wound around the rotating roller, and the other end of the pull rope is connected to the side of the second movable plate away from the first movable plate.

[0010] One side of the flexible connecting plate is connected to the outer edge of one side of the first movable plate and the second movable plate, respectively.

[0011] Based on the above technical solution, the present invention can be further improved as follows.

[0012] Furthermore, the protective side plate and the movable plate assembly are provided in two sets, and the two protective side plates and the two sets of movable plate assemblies together form a protective frame.

[0013] Furthermore, when the two sets of first and second movable plates are parallel, one edge of each of the two flexible connecting plates overlaps.

[0014] Furthermore, an L-shaped connecting rod is provided between the first gear and the second gear. The right-angle end of the L-shaped connecting rod is rotatably connected to the first gear, one end of the L-shaped connecting rod is rotatably connected to the second gear, and the other end of the L-shaped connecting rod is rotatably connected to a transmission rod. The other end of the transmission rod is rotatably connected to the protective side plate.

[0015] The beneficial effects of this utility model are as follows: This utility model provides a bidirectional sand-laying device for a sand mold 3D printer, which has the following advantages:

[0016] 1. This utility model provides multi-directional protection for the printer nozzle by setting up a protective side plate, a first movable plate, a second movable plate, and a flexible connecting plate. This solves the problem that existing 3D printer nozzles usually do not have a safety guard, and avoids the problem that material is easily splashed when the laying direction is changed, and that external impurities and dust can easily mix into the laying area, affecting the quality of the finished product.

[0017] 2. This utility model drives the rotating roller to rotate via a drive motor. The rotating roller winds up the pull rope, thereby flipping the first and second movable plates toward the drive motor. This makes the side with the first and second movable plates open, allowing for bidirectional laying and control of opening and closing, which is convenient for cleaning and production operations.
