Current status of coins circulation and coin clearing device development of our country were analyzed. The main reasons restricting coins issuance and circulation were discussed. The main mechanisms of rotary slide rail type coin clearing were combined with bag molding filling and sealing packaging equipment, which completely solved the automation problems from clearing to packaging, greatly improved the automation degree of coin clearing equipment, improved work efficiency, and effectively reduced the labor intensity of cashier personnel. The development process of the full automatic coin clearing and packaging machine was introduced in detail from aspects of rational program design of equipment working principle and process, internal key structural component design, automatic control system design, and overall modeling design.
