action
The rotation is controlled by frequency conversion motor, the expansion and contraction are controlled by the oil cylinder, the centralization is controlled by the reduction motor, the press is controlled by the oil cylinder, the unwinding is controlled by the reduction motor, and the brake is pneumatic disc brake.
Ability to
Bearing weight: Maximum 30000kg
Bearing width: Maximum 2200mm
Coil outer diameter: maximum φ2700mm
Coil inner diameter: φ508mm
Linear velocity: Max 200m/min
Alignment stroke: ±150mm
Power main motor: 22kw frequency conversion motor
Center movement: 1.5kw reduction motor
Unwinding motor: 2.2kw reduction motor
Expansion and contraction: oil cylinder φ150×150mm
Press material: oil cylinder φ63×300mm
Control of tension
The uncoiler is used to provide reverse torque and the clip-feed machine to establish tension control of the production line to avoid uncoiling due to rotational inertia.
Roll stripping machine
The unwinding roller is φ250×400, the surface is coated with adhesive, and the middle is slotted for easy to pull out the packing belt
note
· The main motor transmits power to the spindle through a multi-stage gear reduction box.
· The unwinding mode is upper unwinding, which can realize manual unwinding and automatic unwinding.
· In manual mode, unwinding and manual centering operation can be realized on the operating table and wireless remote control handle
