Automatic balers control system consists of core control unit for PLC, HMI and the composition of the core control unit uses LG "PLC" control, hydraulic system pressurized core part of the baler, the reliability of its work will determine the baler action is normal and reliable, which has become a key oil temperature control metal hydraulic baler hydraulic control section. Machinery and equipment for mechanical and electrical integration, automation, intelligent, a unit making the design Reflections comprehensive, which would consider the important parts. The life of each product by a core component decision, and that the core component is often the most valuable one. The core components such as balers for the movement; the core components of the motor sealing machine; contraction of the core component is the furnace Road; winding machine production has been modularized, the core components in each module. The core components of the vacuum packaging machine is a vacuum pump. They are rotary vane vacuum pump and now most small vacuum packaging machines. This is enough to see the high-tech requirements of packaging machinery production.
