Description

Technical Field

[0001] This utility model belongs to the field of additive manufacturing technology, specifically a cleaning device for additive manufacturing metal powder screens. Background Technology

[0002] Additive manufacturing, commonly known as 3D printing, is a technology that creates three-dimensional objects by adding materials layer by layer. Its manufacturing logic is completely opposite to that of traditional subtractive manufacturing.

[0003] In the additive manufacturing process, metal powder needs to be sieved through a screen to ensure uniform particle size. However, the screen is easily clogged by metal powder after use, requiring cleaning equipment. Although existing cleaning equipment can use ultrasonic cleaning, ultrasonic cleaning alone is difficult to remove highly adhesive powder. Manual brushing is still required afterward, which not only increases the workload of operators but also reduces cleaning efficiency. Therefore, it needs to be improved. Utility Model Content

[0004] The purpose of this invention is to address the above problems by providing a cleaning device for additive manufacturing metal powder screens, which has the advantage of high cleaning efficiency.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a cleaning device for additive manufacturing metal powder screens, comprising an ultrasonic cleaner, a drive motor fixedly connected to the back of the ultrasonic cleaner, a rotating shaft fixedly sleeved at the other end of the output shaft of the drive motor, a rotating rod fixedly sleeved on the outer surface of the rotating shaft, a round shaft fixedly sleeved inside the other end of the rotating rod, a crossbar movably connected to the outer surface of the round shaft, and two connecting plates fixedly connected to the left and right sides of the front of the crossbar, the other ends of the two connecting plates penetrating through the ultrasonic cleaner and extending into the interior of the ultrasonic cleaner, and a brush plate fixedly connected between the two connecting plates.

[0006] As a preferred embodiment of this utility model, the ultrasonic cleaner has two round rods fixedly installed inside, and the outer surfaces of the two round rods are respectively movably sleeved with the inner surfaces of two connecting plates.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] like Figures 1 to 6 As shown, this utility model provides a cleaning device for additive manufacturing metal powder screens, including an ultrasonic cleaner 1. A drive motor 2 is fixedly connected to the back of the ultrasonic cleaner 1. A rotating shaft 3 is fixedly sleeved at the other end of the output shaft of the drive motor 2. A rotating rod 4 is fixedly sleeved on the outer surface of the rotating shaft 3. A round shaft 5 is fixedly sleeved inside the other end of the rotating rod 4. A crossbar 6 is movably connected to the outer surface of the round shaft 5. Connecting plates 7 are fixedly connected to the left and right sides of the front of the crossbar 6. There are two connecting plates 7. The other ends of the two connecting plates 7 pass through the ultrasonic cleaner 1 and extend into the interior of the ultrasonic cleaner 1. A brush plate 8 is fixedly connected between the two connecting plates 7. When the drive motor 2 is running, the rotating shaft 3 will drive the rotating rod 4 to rotate, which will cause the round shaft 5 to rotate and squeeze the crossbar 6 and drive it forward. This will cause the two connecting plates 7 to drive the brush plate 8 to move forward and brush the screen, achieving the purpose of automatically removing highly adhesive powder.

[0023] The ultrasonic cleaner 1 has two round rods 9 fixedly installed inside. The outer surfaces of the two round rods 9 are movably sleeved with the inner surfaces of the two connecting plates 7 respectively. The design of the two round rods 9 serves to limit and support the two connecting plates 7, ensuring the stability of the horizontal movement of the two connecting plates 7.

[0024] The ultrasonic cleaner 1 has a cover plate 10 hinged to its top, and a handle 11 is fixedly connected to the front of the cover plate 10. This design makes it easy to rotate the cover plate 10 by pulling the handle 11 and release the sealing effect on the top of the ultrasonic cleaner 1.

[0025] The inner surface of the cover plate 10 is movably fitted with a U-shaped frame 12. An installation shaft 13 is fixedly installed on the inner side of the U-shaped frame 12. A rotating plate 14 is movably fitted on the outer surface of the installation shaft 13. A first spring 15 is fixedly connected to the outer side of the rotating plate 14. The other end of the first spring 15 is fixedly connected to the inner side of the U-shaped frame 12. Pressing the two rotating plates 14 will squeeze the two first springs 15 and rotate them around the installation shaft 13. Then, the screen is placed between the U-shaped frames 12 and the two rotating plates 14 are released. Under the elastic force of the two first springs 15, the two rotating plates 14 will rotate and reset to clamp and fix the screen.

[0026] The cover plate 10 is fixedly connected to the top of a vibration motor 16. The other end of the output shaft of the vibration motor 16 is fixedly sleeved with a transmission shaft 17. A protrusion 18 is fixedly sleeved on the outer surface of the transmission shaft 17. The top of the protrusion 18 is movably connected to the top of the inner cavity of the U-shaped frame 12. The top of the cover plate 10 is fixedly connected with two second springs 19. The tops of both second springs 19 are fixedly connected to the top of the inner cavity of the U-shaped frame 12. When the vibration motor 16 is running, the transmission shaft 17 will drive the protrusion 18 to rotate. As the protrusion 18 rotates, the locking effect on the U-shaped frame 12 will be released. At this time, under the action of the two second springs 19, the U-shaped frame 12 will vibrate up and down, so that the particles in the screen can vibrate and fall off, improving the cleaning effect of the screen.

[0027] Among them, a limiting ring 20 is fixedly sleeved on the outer surface of the U-shaped frame 12. The limiting ring 20 is rectangular in shape. The design of the limiting ring 20 serves to limit the vertical vibration distance of the U-shaped frame 12, thereby preventing excessive vibration of the U-shaped frame 12.

[0028] The ultrasonic cleaner 1 has a valve 21 fixedly installed on its right side, and a drain pipe 22 is fixedly connected to the right side of the valve 21. When the valve 21 is opened, the ultrasonic cleaning fluid inside the ultrasonic cleaner 1 can be discharged to the outside through the drain pipe 22.

[0029] Working principle and usage process of this utility model:

[0030] When cleaning the screen, first pull the handle 11 to rotate and open the cover plate 10. Then press the two rotating plates 14 to squeeze the two first springs 15 and rotate them around the mounting shaft 13. Then place the screen between the U-shaped frames 12 and release the two rotating plates 14. Under the elastic force of the two first springs 15, the two rotating plates 14 will rotate and reset to clamp and fix the screen. At this time, pull the handle 11 again to rotate and reset the cover plate 10. The screen is now in the cleaning liquid in the ultrasonic cleaner 1. Start the ultrasonic cleaner 1 and drive motor 2. The rotating shaft 3 will drive the rotating rod 4 to rotate, which will cause the round shaft 5 to rotate and squeeze the crossbar 6 and move it forward. This will cause the two connecting plates 7 to drive the brush plate 8 to move forward and brush the bottom of the screen, achieving the purpose of automatically removing highly adhesive powder. When used with the ultrasonic cleaner 1, the cleaning effect of the screen is improved.

[0031] Since the particles are located inside the screen and are not easy to fall off, when the vibration motor 16 is started, the transmission shaft 17 will drive the protrusion 18 to rotate. As the protrusion 18 rotates, the locking effect on the U-shaped frame 12 will be released. At this time, under the action of the two second springs 19, the U-shaped frame 12 will vibrate up and down as a whole, so that the particles inside the screen can vibrate and fall off, further improving the cleaning effect of the screen.
