Abstract: On the basis of the research on the domestic and foreign binding machine, this article describes a new model of binding machine. Its compact structure is easy to operate and maintain. solidworks software is applied for modeling. Based on the plc-300 cpu module control system, not only ensures the speed and reliability bunch, but also gives good man-machine interactions. Hydraulic system saves energy effectively. Hydraulic components are distributed in the surface of its structure and easy to check repair.
