AI Technical Summary
The existing hydraulic systems of paper box forming machines have problems of high energy consumption and high equipment cost. In particular, paper box forming machines with hot melt glue machines consume more electricity when operating at high power, and the configuration of multiple hydraulic stations leads to excessively high equipment costs.
Two motors are connected to the same oil tank, each connected to a different oil pump, and controlled individually by a solenoid valve. Each oil pump is a variable pump to achieve oil pressure control with different power. Combined with the oil return tank design, the oil is collected and concentrated, reducing vibration and space occupation.
It achieves energy saving and power saving, reduces equipment costs, and maintains equipment stability and environmental cleanliness.
