Technical Field
[0001] This utility model relates to the field of powder transfer equipment technology, and more specifically, it relates to a metal powder transfer device. Background Technology
[0002] Metal powders are often used in 3D printing equipment and as coatings for some items, such as ceramics and jewelry, for coloring and decoration. Metal powders are also raw materials for some metallurgical products and industrial products. During processing, some metal powders generally need to be transported. During transport, the metal powders are usually poured into transport containers, which are then moved to the vicinity of a transport vehicle by forklifts or mobile trolleys, and then transported to the designated area by the transport vehicle.
[0003] A search revealed that Chinese utility model patent application number CN202320555446.5 discloses a metal powder transfer device, including a storage box. Electric push rods are fixed to the four corners of one edge of the storage box via connecting plates, and a base plate is fixed to the output end of the electric push rods. Universal wheels are fixed to the four corners of the bottom edge of the storage box. A rotating shaft is symmetrically fixed to one side of the storage box, and a handle is rotatably connected to one side of the storage box via the rotating shaft. The electric push rods drive the storage box, thereby causing the base plate to contact the ground.
[0004] When in use, the metal powder needs to be discharged from the discharge pipe of the storage device into the storage box. During the process of discharging the metal powder into the storage device, a large amount of dust is generated. The dust is easily scattered into the surrounding air, causing pollution to the surrounding air and resulting in the loss of metal powder. In addition, when discharging the metal powder inside the storage box, the first pull plate needs to be pulled out from the bottom of the storage box. The metal powder inside the storage box will fall onto the bottom plate, making it inconvenient to discharge the metal powder to the corresponding position. Utility Model Content

Beneficial effects
[0015] Compared with the prior art, the present invention provides a metal powder transfer device, which has the following advantages:
[0016] 1. Move the conical hopper to below the discharge pipe of the metal powder storage equipment. By rotating the threaded pipe, the screw moves outward, driving the fixed plate, the second feed pipe, and the conical hopper upward. This causes the inner wall of the conical hopper to press against the bottom of the discharge pipe of the metal powder storage equipment. The metal powder discharged from the discharge pipe of the metal powder storage equipment is then directly discharged into the interior of the storage tank through the second feed pipe and the first feed pipe, preventing dust from scattering everywhere, avoiding pollution to the surrounding environment, and preventing the loss of metal powder.
[0017] 2.

[0028] Please see Figures 1-5 A metal powder transfer device includes a storage box 1. Multiple support legs 25 are fixedly connected to the bottom of the storage box 1. Each support leg 25 is equipped with a self-locking caster wheel 26 at its bottom for easy movement. A sealing cover 2 is installed at the top of the storage box 1, and a sealing gasket 24 is provided between the sealing cover 2 and the storage box 1 to ensure a tight seal. A first feed pipe 3 is connected to the top of the sealing cover 2. A second feed pipe 4 is slidably disposed inside the first feed pipe 3. An annular groove 11 is provided inside the first feed pipe 3. A sealing ring 12 is provided to ensure the sealing between the first feed pipe 3 and the second feed pipe 4. A first valve 5 is installed on the second feed pipe 4. A conical bucket 6 is fixedly connected to the top of the second feed pipe 4. A fixing plate 7 is fixedly connected to the upper outer side of the second feed pipe 4. Multiple telescopic rods 8 are fixedly connected between the fixing plate 7 and the sealing cover 2. A screw 9 is fixedly connected to the bottom of the fixing plate 7. A threaded pipe 10 is rotatably connected to the top of the sealing cover 2. The screw 9 is screwed into the inside of the threaded pipe 10. An anti-slip sleeve 13 is fixedly connected to the outside of the threaded pipe 10 to increase the friction of the surface of the threaded pipe 10.
[0029] Specifically, the conical hopper 6 is moved to the bottom of the discharge pipe on the metal powder storage device. By rotating the threaded pipe 10, the screw 9 moves outward from the threaded pipe 10. The screw 9 drives the fixed plate 7, the second feed pipe 4, and the conical hopper 6 to move upward, so that the inner wall of the conical hopper 6 is pressed against the bottom end of the discharge pipe of the metal powder storage device. The conical hopper 6 is easy to match with discharge pipes of different diameters. The metal powder discharged from the discharge pipe of the metal powder storage device is directly discharged into the interior of the storage box 1 through the second feed pipe 4 and the first feed pipe 3, avoiding the dust from flying around, avoiding pollution to the surrounding environment, and avoiding the loss of metal powder.
[0030] Please see Figure 2 and Figure 5 The storage tank 1 has a first discharge pipe 14 connected to its bottom end. The first discharge pipe 14 extends to the bottom end of one side of the storage tank 1 and is connected to a second discharge pipe 15. A second valve 16 is installed on the second discharge pipe 15. A first motor 17 is installed on the first discharge pipe 14. A first rotating shaft 18 is fixedly connected to the output end of the first motor 17. Spiral blades 19 are fixedly connected to the outer wall of the inner part of the first discharge pipe 14 to facilitate the rapid discharge of metal powder inside the first discharge pipe 14. A second rotating shaft 20 is rotatably connected to the first discharge pipe 14. Multiple stirring plates 21 are fixedly connected to the outer wall of the inner part of the storage tank 1 extended by the second rotating shaft 20. A fixing frame 22 is fixedly connected to the bottom end of the storage tank 1. A second motor 23 is installed on the fixing frame 22. The output end of the second motor 23 is fixedly connected to the second rotating shaft 20 to facilitate the discharge of metal powder inside the storage tank 1 into the inner part of the first discharge pipe 14.
[0031] Specifically, since the first discharge pipe 14 extends to the lower outer side of the storage tank 1 and the second discharge pipe 15 is located on one side of the storage tank 1, it is convenient to move the second discharge pipe to the corresponding position and to discharge the metal powder to the corresponding position or the corresponding equipment. The second motor 23 drives the second rotating shaft 20 and multiple stirring plates 21 to rotate, and the multiple stirring plates 21 stir the metal powder on the bottom side of the storage tank 1, so as to avoid the metal powder from blocking the port of the first discharge pipe 14 and to facilitate the discharge of the metal powder inside the storage tank 1 into the first discharge pipe 14. The first motor 17 drives the first rotating shaft 18 and the spiral blade 19 to rotate, which facilitates the rapid transport of the metal powder inside the first discharge pipe 14 and increases the discharge rate of the metal powder inside the storage tank 1.
[0032] In summary, when using the overall equipment:
[0033] The storage tank 1 is moved by rolling the casters 26 on the ground, positioning the conical hopper 6 directly below the discharge pipe of the metal powder storage equipment. By rotating the threaded pipe 10, the screw 9 moves outward, causing the fixed plate 7, the second feed pipe 4, and the conical hopper 6 to move upward, bringing the inner wall of the conical hopper 6 against the bottom end of the discharge pipe of the metal powder storage equipment. At this point, there is no gap between the conical hopper 6 and the discharge pipe. The casters 26 are then locked, and the first valve 5 is opened. The metal powder inside the metal powder storage equipment is discharged into the storage tank 1 through the discharge pipe, the conical hopper 6, the second feed pipe 4, and the first feed pipe 3. Once a certain amount of metal powder has been discharged into the storage tank 1, the first valve 5 is closed, and then the threaded pipe 10 is rotated. Move the fixed plate 7 and the conical hopper 6 downwards, so that the conical hopper 6 is below the discharge pipe, and then push it away. Push the second discharge pipe to the position where the metal powder needs to be discharged. Then lock the caster 26, and then open the second valve 16. Then connect the first motor 17 and the second motor 23 to the external power supply. The second motor 23 drives the second rotating shaft 20 and multiple stirring plates 21 to rotate. The multiple stirring plates 21 stir the metal powder on the bottom side of the storage tank 1, so that the metal powder inside the storage tank 1 is discharged into the first discharge pipe 14. The first motor 17 drives the first rotating shaft 18 and the spiral blade 19 to rotate. The rotation of the spiral blade 19 transports the metal powder inside the first discharge pipe 14 and discharges it through the second discharge pipe 15 to the corresponding position.
