Aiming at overcoming the shortcomings of the existing material dispensing technology, a semi-automatic pellet racking machine was designed, which multiply controlled the entire packaging process by the controlling system. Combining the bilateral asymmetric oscillating structure with the conveyor belt powered by the stepper motor, the racking machine distributed the pellets apart by taking two steps. The infrared count structure and aggregate silo were used to make the pellets discharged in accordance with a certain number of packaging, while the total number of pellets and the number of times were recorded. The device was concise, ingenious and could ensure the accuracy and efficiency of the entire packaging process through the multi-control program. With this device, not only the shortage of the manual packaging in the safety and health aspects could be avoided, but also the user requirements on the granular material dispensing accuracy could be met.
