The fully automatic heavy-duty material frame is a model that was born by adding a loading trolley device to the standard hydraulic heavy-duty material frame. The material roll can be smoothly moved to the rack-retracting reel drum. The biggest advantage is that It can realize the automatic feeding, feeding, shrinking and unwinding of the material rack, and it is the most effective and reliable unwinding equipment for large and thick plate coil unwinding.
Automatic heavy-duty material rack has a load-bearing surface of the loading platform of the V-type, the trolley travel drive is a hydraulic motor (the travel speed is adjusted by adjusting the oil pressure flow), and the trolley is driven up and down as a hydraulic cylinder, and the control is controlled by Simple point-and-click operation control of the operating handle. The automatic heavy-duty material frame operation handle box has three kinds of function control: the trolley rises and falls, the trolley advances and retreats, and the rack is tightened and contracted.
When automatic heavy-duty material frame is used, after placing the material roll on the V-type loading platform, turn the rising knob switch on the operation handle of the material frame trolley to control the hydraulic valve to open, and the hydraulic oil pumped by the hydraulic station enters. The rodless cavity of the hydraulic cylinder pushes the piston rod of the hydraulic cylinder upward, and the piston rod of the hydraulic cylinder pushes the V-shaped loading table to move upwards, and when it rises to the highest point, the center of the coil runs to the strip shear The center of the heavy-duty material frame is coincident. At this time, the control hydraulic valve is closed, and the piston rod of the hydraulic cylinder stops moving upward.
Twist the forward knob switch on the operating handle of the automatic heavy-duty material trolley. The positive rotation of the hydraulic motor drives the sprocket shaft to rotate forward. The sprocket shaft drives the first sprocket to rotate forward. The first sprocket drives the second chain through the chain. The wheel rotates forward, the second sprocket drives one of the rear wheels to rotate forward, and the other rear wheel and the two front wheels move, so that the entire material rack loading trolley moves forward on the guide rail, when the material rack is loaded with the trolley When moving to the position of the loading position of the loading position, the material roll is sleeved on the material frame expansion and contraction reel; then, the hydraulic motor controls the reversing of the traveling motor, the traveling motor drives the sprocket shaft to reverse, and the sprocket shaft drives the first chain. The wheel is reversed, the first sprocket drives the second sprocket to reverse through the chain, the second sprocket drives one of the rear wheels to reverse, and the other rear wheel and the two front wheels are driven to make the entire material rack loading trolley Moving backwards on the guide rail, when the material rack loading trolley moves to the initial position and the hard limit stop is placed, the traveling motor stops reversed, ready for the next loading.
