219×9mm Uncoiler

The operator operates the crane to directly lift the steel coil to the feeding center of the uncoiler. The uncoiler starts the mandrel expansion function to tightly stretch the steel coil onto mandrel. The uncoiler rotates actively to the uncoiling position. Manually, the welding strip (the welding strip fixed to the plate head after slitting) or the packing strap is cut off and removed (this process can be completed by the crane operator). The pressure rollers are used to guide the strip to the clamping and leveling workstation. The clamp rollers hold the steel strip forward and enter the leveler to level the strip head.

Main Equipment Introduction

1. Uncoiler

Function：

Used for feeding, uncoiling, and supporting steel coils, providing raw materials for the production line.

Equipment Composition：

The uncoiler consists of active double-mandrel cantilever uncoiler, pressure roller device (with anti-loosening function), head finding drive device, shovel head straightening device, stopper device, photoelectric detection elements, hydraulic station, and braking system.

Equipment Structure：

The uncoiler adopts active double mandrel cantilever structure. It is composed of shovel head device, press roller device, stopper device, braking system, etc. The cantilever mandrel is hydraulic expansion and contraction type, which can achieve active, passive, head finding, and anti-loosening functions; there is an expansion and contraction mandrel on each side, hydraulically rotating; the straight head function of the shovel head is realized by hydraulic cylinder; it is equipped with head straightening and pressing roller device, coil anti-loosening device, inertia braking damping device, hydraulic system and electrical control operating system. It has the function of bidirectional uncoiling (forward and reverse feeding).

Basic Parameter：

Load capacity of uncoiler: Max 15 tons per side

Rotation mode of uncoiler: Driven by hydraulic motor

Structural form of mandrel: Hydraulic wedge expansion

Uncoiling speed: ~12m/min (variable frequency speed control)

Swing mode of shovel blade: Hydraulic swing

Extension mode of shovel blade: Hydraulic extension

Drive mode of pressing guiding roller: Hydraulic motor
