Description

Technical Field

[0001] The invention relates to the technical field of metal powder processing, and in particular to a production, processing and screening device for metal powder. Background Art

[0002] Metal powder refers to a group of metal particles with a size of less than 1mm. It includes single metal powder, alloy powder and certain refractory compound powders with metallic properties. It is the main raw material for powder metallurgy. Metallic elements are generally silver-white. When metal is under certain conditions, it becomes black powder. Most metal powders are black.

[0003] Metal powder, as an important raw material in the modern industrial field, is a tiny granular substance made of metal or its alloy through a specific process. Due to their unique physical and chemical properties, these powders play a vital role in many high-tech and traditional industrial fields such as 3D printing, powder metallurgy, surface spraying, catalyst preparation, etc. The particle size, shape, distribution uniformity and other characteristics of metal powder directly determine its performance in the application and the quality of the final product. However, in the production and processing of metal powder, the screening link has become a technical challenge that cannot be ignored. The purpose of screening is to classify the powder according to the particle size to meet the specific needs of different application fields.

[0035] Working principle:

[0036] When the metal powder needs to be screened, the metal powder is poured into the first through hole 4. At this time, the first motor 38 drives the cam 39 fixedly connected thereto to rotate, and the raised portion of the cam 39 pushes the first connecting plate 34. The first connecting plate 34 drives the first sliding rod 35 fixedly connected thereto to slide in the first slide groove. At the same time, the first connecting plate 34 squeezes the first spring 36, and the movement of the first sliding rod 35 drives the blocking plate 37 to move. At this time, the first through hole 4 and the second through hole 32 are opened, and the metal powder in the first through hole 4 flows into the unloading tray 311. The dust in the housing 1 is discharged into the collecting bag 5 through the second through hole 32, so as to prevent the dust from entering the air.

[0037] When the raised portion of the cam 39 rotates to a position where it does not touch the first connecting plate 34, the first spring 36 resets, pushing the first connecting plate 34 to move, the first connecting plate 34 drives the first sliding rod 35 to move, and the second sliding rod drives the blocking plate 37 to reset, blocking the first through hole 4 and the second through hole 32. During the resetting process, the blocking plate 37 can also push dust into the second through hole 32.

[0038] The metal powder entering the discharge tray 311 is rotated by the second motor 3132, driving the first bracket 314 and the second bracket 315 to rotate on the rotating shaft 313. The rotation of the first bracket 314 and the second bracket 315 drives the connecting shaft 3144 and the stirring plate 3145 to move. The movement of the connecting shaft 3144 drives the rotating rod 3143 to move. The movement of the rotating rod 3143 drives the first slider 3141 and the second slider 3142 to slide in the arc groove 3131. The agglomerated metal powder is stirred and separated by the rotation of the stirring plate 3145.

[0039] The separated metal powder enters the first screening net 320 through the plurality of discharge ports 312 on the discharge tray 311. At this time, the third motor 317 fixedly connected to the fixed frame 316 rotates, and the rotation of the third motor 317 drives the first rotating plate 318 fixedly connected thereto to rotate. The rotation of the first rotating plate 318 drives the second rotating plate 319 rotatably connected thereto to rotate. The rotation of the second rotating plate 319 drives the first screening net 320 to slide in the housing 1. The movement of the first screening net 320 drives the first support rod 321, the second support rod 322, and the third support rod 324 to rotate. 24 and the fourth support rod 325 move, the first support rod 321 and the second support rod 322 drive the fourth screening net 330 to slide in the shell 1, and at the same time the first screening net 320 drives the second spring 323 to squeeze and reset between the first screening net 320 and the second screening net 328, thereby driving the second screening net 328 to slide in the shell 1, the third support rod 324 and the fourth support rod 325 move to drive the second connecting plate 327 to move, and the second connecting plate 327 drives the third spring 326 to squeeze and reset between the second connecting plate 327 and the second screening net 328.

[0040] The metal powder is screened by the first screening net 320 , the second screening net 328 , the third screening net 329 and the fourth screening net 330 , so as to improve the screening efficiency of the metal powder.
