Multi-material mixing and counting packaging machine is an automatic packaging equipment with multiple functions, including material counting, mixing, weighing and packaging. It can mix different materials according to the preset ratio and then count and pack them, so as to improve production efficiency and product quality. The machine is usually composed of material conveying system, counting system, mixing system, weighing system and packaging system and other parts. Among them, the counting system is the core part of the machine, which can quickly and accurately count materials of various shapes and send them to the mixing system. The mixing system will mix different materials according to the preset ratio, and then send the mixed materials to the weighing system for weighing. Finally, the packaging system will pack the weighed materials for easy transportation and storage. The machine has the characteristics of high efficiency, precision and stability, which can greatly improve production efficiency and product quality.
