1、 Overview:

The KLF-50C vacuum powder packaging machine is a ultra-fine powder packaging machine developed by Weifang Kelei Machinery specifically for floating materials with vacuum degassing function. It is designed with humanized energy-saving and environmental protection concepts, and draws on the technology of similar foreign products to optimize the design according to the specific situation of various powders in China. It adopts a spiral blade structure, adjusts the feeding speed through stepless frequency conversion, and controls the feeding accuracy. It has the characteristics of accurate measurement, rigorous and reasonable structure, flexible operation, and no need to sew the valve pocket. It can be widely used in various fields such as chemical, metallurgical, mineral, light industry, agriculture, building materials, etc. It is a fine powder with strong fluidity, low loose packing ratio (low bulk density), and high gas content, such as battery negative electrode materials, graphite powder, carbon black, as well as high gas content silicon dioxide powder.

Solved the problem of difficulty in packaging floating materials.

3、 Structural principle:

1. According to production needs, the packaging weight, precise measurement value, packaging speed, and bagging size can be freely adjusted.
2. New technology, vacuum degassing, solves the packaging problem of materials with high gas content. Smaller packaging bags can be used, which not only reduces the cost of packaging bags, but also makes the appearance of packaging bags neat and beautiful, improving the product's grade.
3. The filling method is achieved by controlling the conveying speed with a frequency converter and adding a discharge dual speed valve to achieve accurate control of secondary and tertiary flow rates. No matter how much material is in the upper silo, it can be accurately packaged.
4. Fast packaging speed, saving manpower and reducing costs. The improvement of packaging capacity during large-scale production by enterprises plays an important role in reducing packaging costs. For example, it only takes 28-32 seconds to complete the packaging of 25kg/bag of 3000 mesh sliding stone powder.
5. When packaging high hardness powders such as minerals with wear resistance, maintenance is usually required due to component wear. But the packaging machine uses wear-resistant parts, which reduces maintenance costs.
6. The airflow injection technology solves the problem of poor powder flowability affecting packaging.
7. Intelligentization adopts computer control method, and all pneumatic, electric actions and instruments in the packaging process are programmed and controlled by imported PLC. Imported weighing instruments and precision sensors are used to achieve precision speed packaging. (There is also a touch screen operation method, which is fully operated in Chinese, with very simple settings and fast worker training.)
8. Easy to operate, easy to maintain, one click start configuration, and the entire packaging process can be completed by only one person. The process of bagging, filling at high and low speeds, and loosening the bag is completed in one go. Easy maintenance, few vulnerable parts, convenient disassembly and maintenance.
