The decoiler plays a pivotal role as an auxiliary peripheral device in automated production processes. This powerful tool seamlessly integrates with various processing equipment, including punch presses, hydraulic presses, shearing machines, laser cutting machines, and forming machines. Designed to unwind or rewind coils of material, the decoiler streamlines production and enhances operational efficiency. In this article, we will delve into the intricacies of the decoiler, shedding light on its structure, working principle, and practical usage. Whether you are a seasoned professional or a novice user, this comprehensive guide will equip you with the knowledge required for optimal utilization, maintenance, and longevity of this remarkable device.

Structure of the Decoiler:

The decoiler comprises several key components that synergistically contribute to its functionality. Understanding the structure of the decoiler is essential for harnessing its capabilities effectively. Let’s take a closer look at each component:

  1. Body: The body forms the core framework of the decoiler, providing stability and support throughout the operation. Constructed with utmost precision, it ensures seamless functionality and longevity.
  2. Main Spindle: The main spindle extends outward from the body, serving as a pivotal component for the decoiling process. It is equipped with a backrest wheel near the body, which prevents material deviation, and a hand crank, installed through a spindle sleeve, for convenient manual control. The hand crank features an anti-slip handle, ensuring a secure grip during operation.
  3. Material Support Tile: Mounted on four sets of supporting connecting rods, the material support tiles are strategically placed along the side of the main spindle. These tiles play a crucial role in accommodating the material coil. By adjusting the diameter of the material coil, facilitated by the supporting connecting rods, the decoiler can handle various coil sizes. The outer surface of the material support tiles is coated with a wear-resistant and non-slip layer, enabling smooth and secure material handling, even for heavy-duty applications.
  4. Induction Control Rod: Situated on the outer side wall of the body’s bottom, the induction control rod plays a pivotal role in maintaining precise control during operation. This rod is mounted via an edge plate, ensuring accurate and reliable performance.
  5. A-Type Iron: An essential component, the A-Type iron is installed diagonally on the inner side of each material support tile. These irons, typically four in number, provide additional support and stability to the material coil, preventing potential slippage or mishaps during the decoiling process.
  6. Electrical Control Box: Located on the side of the body, the electrical control box serves as the nerve center of the decoiler. Housed within this control box is a motor, responsible for powering the entire system. The electrical control box enables precise equipment control, enhancing the overall efficiency and performance of the decoiler. To minimize vibrations, a rubber shock pad is strategically placed beneath the motor, ensuring smooth and stable operation.

Working Principle of the Decoiler:

Understanding the working principle of the decoiler is vital for harnessing its capabilities optimally. Let’s delve into the step-by-step process of operating this remarkable device:

1.Power Connection: Begin by connecting the power supply to the control electrical box of the decoiler. Ensure a stable and reliable power source to facilitate uninterrupted operation.

2.Diameter Adjustment: To prepare the decoiler for material handling, rotate the hand crank counterclockwise. This action reduces the diameter of the material support tile, making it smaller than the inner diameter of the coil.

3.Installation of A-Type Iron: Install one A-Type iron diagonally on the inner side of each material support tile, ensuring a secure and stable placement. Proceed to mount the material coil onto the decoiler, positioning it in alignment with the A-Type irons.

4.Tightening the Coil: Once the coil is positioned, rotate the hand crank clockwise. This action tightens the inner circle of the coil, securely holding it in place. Install the remaining two A-Type irons on the other material support tiles for enhanced stability and balance.

5.Leading Out the Material Coil: Carefully lead out the material coil head, ensuring it is properly aligned for smooth and efficient operation. Take caution to avoid any tangling or misalignment of the material.

6.Jog Control Activation: Use the jog control feature on the electrical control box to initiate the decoiler. This function allows you to start the decoiler gradually, ensuring controlled and precise operation.

7.Adjusting Induction Control: Depending on your production requirements, adjust the height of the induction control rod accordingly. This adjustment allows you to maintain the desired output length and control the feeding process with precision.

By following these step-by-step instructions, you can effectively utilize the decoiler and maximize its potential in your automated production processes. Remember to prioritize safety measures and regular maintenance to ensure the longevity and optimal performance of the decoiler.


The decoiler serves as an indispensable asset in automated production, seamlessly integrating with various processing equipment. Understanding its structure, working principle, and operation is crucial for achieving efficient and productive outcomes. With its robust components and precise control mechanisms, the decoiler empowers users to handle a wide range of materials with ease. By adhering to proper installation and operational procedures, you can harness the full potential of the decoiler, unlocking new levels of productivity and quality in your manufacturing processes. Stay informed, maintain your decoiler diligently, and witness the transformative impact it can have on your production efficiency.
