In the dynamic landscape of stamping automation, the process of unwinding and feeding coil material stands as a crucial operation. When it comes to steel coil unwinding and feeding, the prevalent method involves using a decoiler with intermittent feeding and pauses. However, challenges arise with conventional decoilers when dealing with substantial material thickness and pronounced elasticity. Issues like material dispersal, asynchronous alignment with machine speeds, and feed elimination can hamper overall efficiency and introduce safety hazards.

Innovative Solution: Augmenting a Material-Pressing Apparatus

To address these challenges, a groundbreaking solution involves enhancing the conventional decoiler with a material-pressing apparatus. This apparatus consists of a fixed arm attached to the machine body, a rocking arm connected to the upper end of the fixed arm and linked to the pressing wheel, and two cylinders affixed to the respective ends of the fixed and rocking arms. Bolts secure the pressing wheel to the upper end of the rocking arm. The upper end of the cylinder connects to the middle of the rocking arm via an intermediate pin, while the lower end is linked to the middle of the fixed arm using a pin. Positioned at the rear of the machine body, the pressing device facilitates loading, installation, and securement of the steel strip coil on the decoiler.

Streamlined Operation for Enhanced Efficiency

During operation, the steel strip coil is placed on the material-supporting tile of the decoiler, with A-type irons on either side for proper positioning. The motor drives the rotation of the material-supporting tile, actively feeding the steel strip. As the steel strip progresses to a leveling machine or a servo feeding machine, its feeding speed exceeds that of the latter. The pressing wheel in the cylinder’s clamping device consistently applies pressure to the steel strip on the material-supporting tile, reducing sagging.

Precision Control for Unparalleled Performance

The inductive rod on the machine body is connected to the collision block inside via a pin, with the collision block linked to the stroke drive switch of the motor. As the steel strip moves forward, the inductive rod swings, causing the collision block to halt the motor when reaching the upper limit of the stroke drive switch, temporarily pausing the unwinding. Subsequently, as the steel strip advances following the leveling machine or servo feeding machine, sagging increases. The inductive rod ascends, and the collision block hitting the lower limit of the stroke drive switch activates the motor, ensuring the continued feeding of the steel strip.

Unmatched Durability and Efficiency

Equipped with the additional material-pressing arm, the decoiler orchestrates the coordinated action of the pressing wheel and the inductive rod to control material coil unwinding and feeding. This ingeniously designed structure guarantees durability, eliminating steel strip material dispersal. Simultaneously, the inductive rod’s movements control the motor’s start and stop, ensuring precise material feeding, synchronization with the stamping production line, and mitigating material scrap. The result is a substantial enhancement in the efficiency of the entire stamping production line, ensuring reliability and safety throughout the unwinding and feeding process.
