Coil unwinding is a critical process in various industrial applications, and to ensure smooth operations, employing the right material-blocking device is essential. In this article, we will explore the significance of material-blocking devices during coil unwinding and discuss two effective options that can revolutionize your production line.

1. The Importance of Material-Blocking Devices

When utilizing the uncoiler, it is crucial to implement a specialized material-blocking device to control the coil’s movement. The purpose of this device is twofold: firstly, it maintains the coil on the same horizontal level as the production line during unwinding, preventing any deviation in the unwound strip; secondly, it secures the coil in place, avoiding slippage, scattering, or collapsing on the support tile. A reliable material-blocking device ensures efficient and safe coil unwinding.

2. The A-Type Iron Blocker: Simplicity and Cost-Effectiveness

The default material-blocking device for the uncoiler is the A-type iron blocker. This device offers simplicity in construction, cost-effectiveness, and an effective blocking effect, making it widely popular. To use the A-type iron blocking device, follow these steps:

  1. Secure the two inner limiters of the A-type iron in position and fasten them with bolts.
  2. Reduce the size of the expanding and contracting drum and place it around the coil, ensuring a tight press against the inner A-type iron.
  3. Manually or using hydraulic pressure, expand the coil to tighten it.
  4. Install the outer A-type iron on the support tile and make multiple fine adjustments based on the material width.
  5. Finally, lock the bolts of the A-type iron to complete the blocking process.

While the A-type iron blocker is effective for limiting coils with relatively narrow widths, it has limitations when dealing with wider coils. Issues such as prolonged installation time, complex adjustments, and suboptimal blocking results arise with larger coils. To address these challenges, an alternative solution comes into play: the blocking arm.

3. The Uncoiler Blocking Arm: An Innovative Solution for Wide Coils

The blocking arm serves as a specialized replacement for the A-type iron blocking device, designed specifically for material-blocking in the uncoiler. It comes with an automated blocking mechanism driven by pneumatic cylinders, offering excellent performance, easy operation, and reduced time consumption. Particularly suitable for various wide and large coils, the uncoiler blocking arm comprises two sets of upper and lower blocking groups, blocking wheel devices, mobile components, frames, and telescopic cylinders.

The key features of the uncoiler blocking arm are as follows:

  • Upper and Lower Blocking Groups: Corresponding to the upper and lower edges of the sheet coil, these groups provide precise and secure blocking.
  • Blocking Wheel Devices: These devices can be moved by the mobile component, allowing them to approach or withdraw from the edges of the sheet coil.
  • Telescopic Cylinders: Activated by their respective telescopic cylinders, the blocking rods of each device can adjust their height and lateral movement, ensuring a custom fit for different coil sizes.
  • Buffer Unit with Elastic Properties: As the blocking rods approach the sheet coil, a buffer unit with elastic properties dampens the impact, prolonging the equipment’s lifespan and ensuring smooth operation.

4. Advantages of the Uncoiler Blocking Arm

The uncoiler blocking arm offers several advantages over traditional methods:

  • Versatility: Suitable for various wide and large coils, the blocking arm accommodates diverse coil dimensions effortlessly.
  • Time Efficiency: The automated blocking mechanism significantly reduces the time required for installation and adjustments, enhancing overall productivity.
  • Damage Prevention: By lifting the blocking rods during coil loading, unnecessary collisions and damage are prevented.
  • Smooth Operation: The use of pneumatic cylinders ensures smooth and precise blocking, optimizing coil unwinding efficiency.

In conclusion, utilizing the right material-blocking device during coil unwinding is vital for the smooth functioning of production lines. While the A-type iron blocker serves as a cost-effective solution for narrower coils, the uncoiler blocking arm emerges as a game-changer for wider coils. Its automated blocking mechanism, versatility, and time efficiency make it an excellent choice for enhancing coil unwinding efficiency.
