Guangzhou Jingke Packaging Equipment Co., Ltd. is a technology-intensive enterprise integrating development, design, manufacturing, and installation. With a team of experienced engineers in automation equipment, we provide extensive theoretical and practical expertise in equipment manufacturing, installation, commissioning, and technical services. Our offerings include automatic quantitative packaging machines for powder and granular materials, automatic batching and mixing packaging lines, powder material classification equipment, and related products such as material conveying, lifting, storage silos, mixing, and dust removal systems. These serve industries like metallurgy, mining, chemical, pharmaceutical, and grain. Our newly developed valve-type vacuum packaging machine focuses on special powder properties. It addresses challenges like low bulk density, poor fluidity, ultrafine particle size, and high air affinity by incorporating solutions for arch breaking, packaging feeding methods, and bag air extraction. This effectively improves packaging speed and accuracy while strictly controlling dust emission to maintain a clean production environment. Working Principle: A pressure difference between the vacuum chamber and the feeding device draws the powder into the packaging bag inside the vacuum chamber, enabling sealed vacuum packaging. First, the packaging box is evacuated to a certain limit. The feed valve opens automatically. Using the packaging bag as a filter, atmospheric pressure forces the material into the bag while a vacuum pump extracts the air. The system simultaneously implements fast and slow feeding, quantitative control, automatic negative pressure detection, automatic sealing of the valve bag, and automatic door opening.
