Recoiler 11-23B2 (Cold Rolled Aluminum Strip Line)

The function of the coiler (S) is the exit end of the production line, and it s function is to coil the cold-rolledcoil into coils to facilitate product transportation. The coiler (S) consists of a reel, a rotary expansion and contraction cylinder, a gear box, a transmission DC motor, a brake, and a base. Cantilevered eight-slot slanted wedge sector plate closed reel structure, hydraulic expansion and contraction, with jaws, with push plate device, AC variable frequency motor speed control transmission. Reel expansion and contraction--diameter expansion process: oil is supplied to the rotary joint of the expansion and contraction hydraulic cylinder, which leads to the oil cavity of the hydraulic cylinder head through the internal oil circuit to drive the piston rod to move backwards, and the piston pulls the inner rod of the main shaft of the reel to move synchronously, thereby The relative displacement of the axial wedge and the fan-shaped plate is made, the axial wedge is pushed to move axially, and the radial wedge and the fan-shaped plate are moved radially outward, so as to realize the diameter expansion of the reel. Reverse oil flow realizes the process of reducing the diameter of the reel. Clamping and loosening of jaws--When the cylinder expands and contracts, the diameter of the cylinder expands and the oil is passed, the cylinder expands and the jaws are tightened. The process of loosening the reverse oil-passing jaws is the same as reducing the diameter of the reel.
