Introduction: Embracing Automation in Coil Decoiling
Fully automatic decoiling machines are transforming the coil decoiling industry by integrating a material-loading trolley system with conventional decoilers. These state-of-the-art machines automate the loading, feeding, expanding, and decoiling processes, making them an indispensable solution for large-scale and thick-plate coil decoiling operations.
Efficient Design and Functionality of Fully Automatic Decoiling Machines
Hydraulic Motor and V-Shaped Support Surface
The material-loading trolley of a fully automatic decoiling machine is designed with a V-shaped load-bearing surface. The trolley’s movement is powered by a hydraulic motor, with speed adjustments made through hydraulic flow regulation. Vertical lifting is achieved using hydraulic cylinders, while control is managed through a straightforward point-control operation via a handle. This operation handle box offers three essential functions: trolley elevation and descent, trolley advancement and retraction, and material rack expansion and contraction.
Coil Lifting and Alignment Process
When a coil is positioned on the V-shaped support surface, the operator manipulates the elevation knob switch on the decoiler’s trolley handle to open the hydraulic valve. Hydraulic oil from the hydraulic station flows into the rodless cavity of the hydraulic cylinder, propelling the piston rod upwards. Consequently, the piston rod elevates the V-shaped support surface and raises the coil. Once the coil’s center aligns with the decoiler’s center, the hydraulic valve closes, stopping the piston rod’s upward movement.
Forward and Reverse Movement Mechanism
By turning the forward knob switch on the fully automatic decoiler’s trolley handle, the hydraulic motor’s forward rotation activates the sprocket shaft. The sprocket shaft rotates the primary sprocket, which, connected by a chain, rotates the secondary sprocket. This rotation drives one of the rear wheels, causing the other rear wheel and both front wheels to follow, moving the entire decoiling machine’s material-loading trolley forward on the guide rail.
Upon reaching the loading position and fitting the coil onto the expanding and contracting drum, the hydraulic motor directs the walking motor’s reverse rotation. This action reverses the sprocket shaft and primary sprocket, rotating the secondary sprocket in reverse through the chain and driving one of the rear wheels to rotate backward. Consequently, the other rear wheel and both front wheels follow, moving the entire decoiling machine’s material-loading trolley backward on the guide rail until it reaches the initial position hard stop. The walking motor then stops its reverse rotation, preparing the machine for the next loading cycle.
Conclusion: The Future of Coil Decoiling
Fully automatic decoiling machines offer a highly efficient and reliable solution for large-scale and thick-plate coil decoiling operations. By automating the loading, feeding, expanding, and decoiling processes, these machines have revolutionized the industry, streamlining operations, and delivering consistent results. As technology continues to advance, fully automatic decoiling machines will undoubtedly play a critical role in the ongoing evolution of the coil decoiling sector.
