Description

Technical Field

[0001] This invention belongs to the field of metal powder processing technology, specifically relating to a metal powder making device with uniform powder particle size. Background Technology

[0002] Metal powder materials have a wide range of applications in industrial fields such as powder metallurgy and metal surface engineering. In recent years, metal 3D printing technology has developed rapidly, making the demand for metal powder raw materials more urgent than ever before, while also placing higher demands on the performance of metal powders.

[0003] Metal powder refers to a group of metal particles with a size of less than 1 mm, including single metal powder, alloy powder, and certain refractory compound powders with metallic properties. In the process of preparing metal powder, it is often necessary to grind the metal into powder and then collect the powder. Existing metal powder making equipment requires screening of metal powder during use.

[0004] In existing metal powder preparation equipment, it is not convenient to distinguish and collect good and bad products during the screening of metal powder particles to prevent them from being stored. During long-term screening, bad products will accumulate in the box, requiring the machine to be stopped for cleaning, which will affect the processing progress and reduce screening efficiency. Utility Model Content

[0005] The purpose of this invention is to provide a metal powder making device with uniform powder particle size. The device can effectively distinguish and guide good products from defective products by screening metal powder particles. At the same time, it can clean the screening plate to prevent clogging, thereby effectively improving screening efficiency.

[0006] The specific technical solution adopted by this utility model is as follows: A metal powder making device with uniform powder particle size includes a support frame, a feed box fixed to the top of the support frame, and a discharge port opened at the bottom of the feed box. The drive mechanism includes a drive motor, the output end of which is fixedly connected to drive teeth. The drive teeth are connected to transmission teeth via a transmission belt. The transmission teeth are fixed to the outside of a transmission rod. The transmission rod is rotatably connected to a support frame, and both ends of the transmission rod are fixedly connected to transmission cams. Each transmission cam is rotatably connected to one end of a transmission plate. A screening box is fixed inside the support frame, and the interior of the screening box is divided into a screening area and a qualified area by a screening plate. Sliding grooves are opened at both ends of the qualified area, and a cleaning frame is slidably connected in the sliding grooves. A cleaning roller brush is rotatably connected to the cleaning frame, and the cleaning roller brush is slidably connected to the bottom of the screening plate. Both ends of the cleaning frame are rotatably connected to the other end of the transmission plate.

[0007] Furthermore, a connecting plate is fixed to the bottom of the screening box on the side of the screening outlet. The interior of the connecting plate is rotatably connected to the impact plate, and an elastic element is assembled between the impact plate and the bottom of the screening box.

[0008] Furthermore, a rotating convex ring is fixed to the outer side of the transmission rod, and the rotating convex ring is rotatably connected to the side of the impact plate away from the connecting plate.

[0015] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific implementations of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0016] like Figures 1 to 4 As shown, a metal powder making device with uniform powder particle size includes a support frame 10, a feed box 11 fixed to the top of the support frame 10, and a discharge port opened at the bottom of the feed box 11. The drive mechanism 20 includes a drive motor 21. The output end of the drive motor 21 is fixedly connected to a drive gear 211. The drive gear 211 is connected to a transmission gear 22 via a transmission belt. The transmission gear 22 is fixed to the outside of a transmission rod 221. The transmission rod 221 is rotatably connected to a support frame 10, and both ends of the transmission rod 221 are fixedly connected to transmission cams 23. Each transmission cam 23 is rotatably connected to one end of a transmission plate 231. The screening box 30 is fixed inside the support frame 10. The interior of the screening box 30 is divided into a screening area 301 and a qualified area 302 by the screening plate 31. Sliding grooves are opened at both ends of the qualified area 302. A cleaning frame 32 is slidably connected in the sliding groove. A cleaning roller brush is rotatably connected on the cleaning frame 32. The cleaning roller brush is slidably connected to the bottom of the screening plate 31. Both ends of the cleaning frame 32 are rotatably connected to the other end of the transmission plate 231.

[0017] In this embodiment, it should be noted that the powder particles are crushed and ground before being fed into the feed box 11, thereby ensuring that the metal powder can be quickly screened out with uniform particle size when passing through the sieve box 30 for subsequent use. The sieve plate 31 has sieve holes. When the metal powder particles enter the sieve box 30, the drive motor 21 drives the drive gear 211, causing the drive gear 211 to mesh with the transmission gear 22, thereby driving the transmission rod 221 to rotate synchronously. The transmission rod 221 then drives the transmission cams 23 located at its two ends to rotate. The transmission plate 231 is rotatably connected and rotatably connected to both sides of the cleaning frame 32. This allows the cleaning frame 32 to move along the sliding groove, causing the cleaning roller brush to rotate under the drive of the cleaning frame 32. This effectively cleans the screening holes on the screening plate 31, preventing particles from clogging the screening holes and ensuring that the screening plate 31 can screen powder particles of uniform size, allowing qualified products to fall into the qualified area 302. At the same time, metal powder particles that do not pass through the screening plate 31 will move along the screening plate 31 to one side of the screening section 301 for centralized collection, thereby processing the metal powder.

[0018] like Figure 2 , Figure 4 As shown, a connecting plate 33 is fixed at the bottom of the screening box 30 on the side of the screening outlet. The interior of the connecting plate 33 is rotatably connected to the impact plate 331. An elastic element is assembled between the impact plate 331 and the bottom of the screening box 30.

[0019] like Figure 3 , Figure 4 As shown, a rotating convex ring 24 is also fixed on the outer side of the transmission rod 221, and the rotating convex ring 24 is rotatably connected to the side of the impact plate 331 away from the connecting plate 33.

[0020] In this embodiment, based on the previous embodiment, when the transmission rod 221 rotates, it will synchronously drive the rotating convex ring 24 to rotate. When the rotating convex ring 24 is running, it will apply a force to the impact plate 331, causing it to rotate with the connecting plate 33 and drive the impact end away from the screening box 30. At the same time, when the impact plate 331 rotates, it will drive the elastic element to extend, allowing the elastic element to store energy. When the rotating convex ring 24 does not apply a force to the impact plate 331, the elastic element will release energy, thereby driving the impact plate 331 to reset. At the same time, the impact head on one side of the impact plate 331 will impact the screening box 30, thereby causing the screening box 30 and the internal screening plate 31 to vibrate, thereby accelerating the screening process and ensuring that the metal powder can move in the screening box 30 and the screening plate 31.

[0021] Preferably, a screening inlet is provided on one side of the top of the screening section 301, and the screening inlet is located opposite to the discharge port. It should be noted that a control valve is fixed at the bottom of the discharge port, and the control valve is connected to the screening inlet through a transmission pipe, so as to effectively control the continuous supply of metal powder and ensure the stability and safety of the screening process.

[0022] Preferably, a screening outlet is provided on the other side of the top of the screening section 301, a conveying plate is fixed at the screening outlet, and a storage box is fixed at the bottom of the conveying plate; wherein, during the preparation process, the unscreened particles will move to the screening outlet in the screening section 301 with the guidance of the screening plate 31, and enter the storage box through the conveying plate, so as to facilitate subsequent processing and crushing to form qualified powder particles.

[0023] Preferably, a qualified outlet is provided on the side of the qualified zone 302 away from the screening inlet, and a collection box is slidably connected to the bottom of the qualified outlet; specifically, the uniformly sized powder particles after screening are effectively transported to the qualified outlet through the guide inside the qualified zone 302, and then effectively collected and stored by the collection box.

[0024] The working principle of this utility model is as follows: Crushed and ground powder particles are fed into the feed box 11. A control valve at the discharge port ensures a continuous output of metal powder during sieving. Turning on the drive motor 21 effectively drives the drive gear 211, which meshes with the transmission gear 22 to drive the transmission rod 221. When the transmission rod 221 rotates, it synchronously drives the transmission cams 23 on both sides. The transmission cams 23 drive the transmission plate 231 to reciprocate, simultaneously causing the cleaning frame 32 to slide in the sliding groove, which in turn drives the cleaning roller brush to clean the screening plate 31, ensuring that the screening plate 31 can effectively sieve the metal powder. Specifically, when the transmission rod 221 rotates... It can also synchronously drive the rotating convex ring 24, causing the rotating convex ring 24 to drive the impact plate 331 away from the screening box 30. When the impact plate 331 moves, it will drive the elastic element to charge. When the rotating convex ring 24 does not apply power to the impact plate 331, the impact plate 331 releases energy through the elastic element and impacts the screening box 30, causing the screening box 30 and the screening plate 31 to vibrate, thereby improving the screening efficiency. At the same time, it can guide the metal powder in the screening area 301 and the qualified area 302 to move; ensure that the qualified powder that passes through the screening moves to the collection box for centralized collection, and transfer the powder that does not pass through the screening plate 31 to the storage box for subsequent crushing processing.

[0025] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
