Standard Accessories

① 8 x A-type iron

②Gantry Induction Frame

③Hand Crank Link Type Expansion

1.A-Type Iron: Our decoiler machines are equipped with A-type iron, a specialized material blocking device that precisely limits the position of the material coil. It ensures the material coil remains level with the production line during uncoiling and prevents material belt deflection. Furthermore, it prevents the material roll from slipping and collapsing on the supporting tile. However, for coil limiters with a wider width exceeding 800mm, we recommend using a material blocking arm to provide a more effective solution.

You can learn more about this feature from this article.
Detailed introduction of the stop arm of the uncoiler.

2.Gantry Induction Frame: Our decoiler machines feature a gantry induction frame that provides automatic control. It operates on the principle that material sag will occur due to the weight of the metal material itself during transmission from the decoiler to the subsequent leveler machine. When the material forms an arc between the decoiler and the leveler machine, it triggers the induction rack to stop the material rack, allowing the decoiler to run automatically. However, for non-metal materials or to manage the uncoiling speed, multiple sets of photoelectric switch light controls can be used as an alternative.

Selective Accessories

Press Arm Feature in Henli Decoiler Machines:

The Press Arm is an optional feature of our decoiler machines designed to maintain the integrity of the coil during the uncoiling process. It functions by pressing the outer ring of the coil, preventing material loosening. This feature is particularly beneficial when dealing with materials with a thickness exceeding 2.0mm or materials with a high yield strength.

However, it’s important to note that not all materials with a thickness greater than 2mm require the use of the Press Arm. If the material is not heavy, employing this function might not be necessary. This flexibility allows Henli Decoiler Machines to be adapted to a wide range of material characteristics and requirements, ensuring optimal performance every time.

Inverter Feature in Henli Decoiler Machines:

The Inverter, or frequency converter, is an important feature of our decoiler machines that allows for precise speed control. This facilitates better coordination with subsequent machines in the production line, such as the leveler machine or coil feeder machine. By allowing for speed adjustments, the Inverter helps reduce material vibration and enhances the stability of the uncoiling process, ensuring smoother operations and superior results with our Henli Decoiler Machines.

If you want to know more about how the inverter plays a role in the decoiler, you can read this article.Detailed introduction of the frequency converter of the uncoiler optional device.

Hydraulic Expansion Device in Henli Decoiler Machines:

Our decoiler machines can be equipped with a Hydraulic Expansion Device, a feature designed to replace the manual expansion method typically used in standard decoilers. This device uses oil pressure to expand the inner diameter of the decoiler, consequently tightening the inner diameter of the supporting tile. This not only reduces the labor intensity associated with the expansion and contraction of the coil but also ensures complete tension.

We generally recommend this device for coils weighing more than 3 tons to optimize efficiency. However, it can also be a valuable addition for rolls weighing less than 3 tons to further reduce labor intensity. This feature demonstrates the adaptability and efficiency of Henli Decoiler Machines in meeting diverse operational demands.

Hydraulic Feeding Trolley in Henli Decoiler Machines:

One of the key features of our decoiler machines is the Hydraulic Feeding Trolley. It is designed to facilitate the smooth transfer of the material coil to the expanding and shrinking reel of the decoiler during feeding. This not only makes coil material changes more convenient and faster but also significantly reduces the labor intensity associated with manual coil loading.

Moreover, the Hydraulic Feeding Trolley effectively mitigates personal safety risks associated with manual coil coiling and prevents potential damage caused by collision between the coil material and the machine. We typically recommend using the Hydraulic Feeding Trolley for material rolls weighing more than 5 tons, demonstrating our commitment to safety, efficiency, and convenience in the operation of Henli Decoiler Machines.

There are some other optional functions, which will not be introduced one by one here. As long as you tell Henli the specifications of the material, we will choose the model for you according to the characteristics of your material, what specifications you should use, and what device you should choose.

Often used in stamping production lines with high material feeding requirements, this model operates efficiently without an electricity connection. For small-scale usage, we recommend contacting Henli to ensure this model is the perfect fit for your needs.

Decoiler with Film Recycling: Ideal for precision stamping processes requiring high surface quality, the Decoiler with Film Recycling applies a protective film to the stamping raw material, preventing surface damage. Typically installed after the leveling machine, this function can also be installed on the decoiler if material leveling isn’t required. The installation process is straightforward, effectively ensuring the protection of your materials.

Utilizing Henli Decoiler Machines for Recoiling:

Our Henli Decoiler Machines can also be utilized for recoiling, a process involving the winding and collection of continuous strip after stamping. Recoiling can be categorized into finished product tape and waste tape, and in most stamping production scenarios, decoilers are commonly utilized for recoiling.

When using a decoiler for waste collection, the appearance and compact layering of the material coil wound on the expansion and contraction reel are not crucial, allowing for the direct use of a standard decoiler. In this context, the decoiler’s primary function is to quickly and efficiently collect waste material without causing any harm to the machine or personnel.

For collecting finished products for packaging or subsequent use, a tensioner is needed before the decoiler. The tensioner is a mechanical device providing consistent tension for the feed strip during the punching process and for the decoiler’s take-up. This ensures that the material roll is collected in a compact, visually appealing, and sturdy manner, thus guaranteeing the quality of the finished product.
