The electric bracket is selected in the corrugated cardboard packaging production line mainly because of its advantages of high efficiency, precision, energy saving, environmental protection, flexibility and controllability. The electric bracket is driven by a servo motor, and can accurately adjust the height and angle to meet the processing needs of cardboards of different specifications, and improve the automation of the production line; at the same time, it does not need to rely on air pumps or hydraulic systems, has lower energy consumption and no oil pollution, is easy to maintain, and has low noise, which is in line with the development trend of modern factories to be intelligent and green. In addition, after the electric bracket is integrated with an intelligent control system, it can also realize remote monitoring and parameter memory, further optimize production efficiency, and reduce the cost of manual intervention.
