Description

Technical Field

[0001] This invention relates to the field of silver-coated copper powder processing technology, specifically to a processing device for flake-shaped silver-coated copper powder. Background Technology

[0002] Flake-shaped silver-coated copper powder is a composite metal powder with a flake-shaped copper core and a silver coating. It combines the low cost of copper with the high conductivity of silver. Through a special process, it is manufactured into a flake structure, which enhances conductivity and dispersibility. It is widely used in electronic pastes, electromagnetic shielding, and other fields, balancing performance and cost.

[0003] A processing device for processing silver-coated copper powder, authorized by announcement number CN215879873U, includes a placement base with an overflow prevention cover rotatably connected to it. A measuring cup is placed on the placement base, and a guide pipe is fixedly connected to the placement base. A hopper is slidably fitted through the top of the guide pipe. A sieving mechanism is rotatably connected to the inner wall of the guide pipe, and a transmission mechanism is fixedly connected to the outside of the guide pipe. A particle size control head is slidably fitted at the bottom of the transmission mechanism. During the processing of silver-coated copper powder, the sieving mechanism sieves the powder with excessively large particles, and the particle size control head extrudes and grinds the excessively large particles, thereby controlling the particle size of the copper powder and ensuring the particle size distribution requirements of the product.

[0004] As shown in the above equipment, the existing processing device for flake-shaped silver-coated copper powder can separate large particles through a screening mechanism and control the particle size of copper powder by extrusion and grinding through a particle size control head to ensure distribution requirements. However, the screening mechanism relies on a rotating screen and arc-shaped bars, which has a weak ability to break up agglomerated materials. It is easy for the screen to be blocked due to agglomeration. In addition, it lacks cleaning components and requires frequent manual cleaning, which affects efficiency. Furthermore, the large vibration amplitude of the equipment during operation can easily lead to unstable screening accuracy and make it difficult to continuously and efficiently separate non-compliant particles.
