Introduction to the Three-in-One Decoiler Straightener Feeder

The three-in-one decoiler straightener feeder is a powerful, all-in-one solution that combines an uncoiler, feeder, and straightener into one efficient machine. With a hydraulic trolley for loading and hydraulic expansion and contraction for coil tensioning, this versatile machine offers increased work efficiency and user-friendly operation. However, as with any complex machinery, issues may arise during long-term use, such as imprecise feeding. In this article, we will explore the common causes of feeding inaccuracies and offer practical solutions to resolve them.

Common Causes of Inaccurate Feeding and Solutions

  1. Die Positioning Problems: For precise feeding in the three-in-one decoiler straightener feeder, positioning pins are typically placed within the die. If material deviation occurs during feeding, it’s likely that the die’s positioning pin is improperly set and needs to be remade.
  2. Coil Quality Issues: Coils with severe burrs, bending, waves, or uneven width can lead to material deviation and inaccurate feeding. To resolve this issue, replace the problematic coil with one that meets the required standards.
  3. Improper Adjustment of Material Blocking Wheel: The tension level of the presser device in the three-in-one decoiler straightener feeder is set based on the material’s properties, thickness, and width. If the material blocking device, guide wheel width, and discharging wheel width are not adjusted correctly, uneven pressure distribution can cause material deviation. Follow the user manual and professional training to properly adjust the material blocking wheels.
  4. Inherent Machine Issues: Factors like misaligned roller installation, large roller roundness error, uneven roller surface coating, abnormal servo system, unreasonable material rack design, air and oil leaks in pneumatic components, and blocked pipelines can contribute to material deviation. Contact the manufacturer for resolution, or seek professional assistance if needed.
  5. Foreign Objects within the Feeding Machine: Iron filings or metal oxide scales on gears or rollers can cause material deviation during feeding or leveling. Perform regular maintenance and cleaning to ensure smooth operation. Lubricate transmission components every 15 days and remove foreign objects from gears and rollers.
  6. Insufficient Roller Pressure or Relaxed Rollers: Vibrations during the three-in-one decoiler straightener feeder’s operation can cause positioning screws to loosen, affecting the leveling feeding accuracy and causing material deviation. Inspect the roller’s tightened state and resolve issues by adding roller groups, increasing spring tension, or augmenting cylinder pressure.


Inaccurate feeding in the three-in-one decoiler straightener feeder can be caused by various factors, including die positioning, coil quality, improper adjustments, inherent machine issues, foreign objects, and insufficient roller pressure. By understanding the root causes and implementing the suggested solutions, you can optimize the performance of your three-in-one decoiler straightener feeder and improve overall productivity.
