Chemical quantitative packaging scale: This machine can automatically complete functions such as quantitative packaging of powder and bulk materials. It integrates weight display, packaging timing, process interlocking, and fault alarm into an independent hanging sensor, with stable signal transmission to ensure weighing accuracy; Limin Company adopts spiral feeding equipment based on the characteristics of powder materials that are not easy to flow. There is an arch breaking device in the silo, which loosens the materials before the spiral blades are transported, making it difficult for the materials to arch. The overall structure layout is reasonable and easy to clean and maintain hygiene; Suitable for various materials ranging from ultrafine powder to large particles, it adopts imported pneumatic components for the actuator, and the pressure at the inlet and outlet of the cylinder can be adjusted, making the work more reliable. The parts in contact with the material can be made of standard 304 stainless steel material or stainless steel material for the entire machine, which meets food hygiene requirements, is corrosion-resistant, and extends the service life of the equipment.

　　The main configuration of the chemical quantitative packaging scale includes: 1. storage bin, 2. conveying bin, 3. feeding port, 4. bag clamping device, 5. electrical control box, 6. steel structure machine main frame, 7. belt conveyor device, 8. sealing device, etc. It has the characteristics of reasonable structure, beautiful appearance, smooth operation, energy saving, easy operation, accurate weighing, etc.
