**Heavy Material Rack Selection Device, Leveling Machine, Pneumatic Press Arm**
[http://www.ruihui.net](http://www.ruihui.net)
Heavy-duty material racks are often equipped with optional devices to enhance stability and performance during the unwinding process. Commonly used options include pneumatic press arms, frequency converters, and oil pressure expansion systems. These accessories help improve the efficiency and reliability of the material discharge.
The **pneumatic press arm** is designed to compress the material roll, preventing it from becoming loose or uncontrolled when the Ruihui heavy material frame discharges. This ensures a more stable and controlled unwinding process. The **frequency converter** allows for variable speed control, making the material rack’s discharge smoother and more consistent. Meanwhile, **oil pressure expansion** replaces manual tightening methods, making it easier to handle large rolls and improving feeding accuracy.
These three components are widely used in Ruihui's heavy material frames and are considered standard options in the industry. However, there are also special devices that are not commonly used but play a crucial role in handling medium and heavy plates, large rolls, and special-shaped materials.
Here are five main types of special equipment available for Ruihui heavy-duty material racks:
1. **Pneumatic Disc Brakes**: For heavier rolls (over 3T), a separate disc brake system is necessary to manage the inertia generated during unwinding. The pneumatic disc brake works in conjunction with the unwinding and shrinking roller to prevent sheet material from spreading due to rotational force.
2. **Pneumatic Material Blocking Device**: Instead of using traditional A-type iron blocks, this device uses an escaping cylinder and two hinged shims to adjust the discharge width. It allows for automatic adjustment, making it more efficient and user-friendly, especially for thick or wide rolls.
3. **Hydraulic Pressure Arm**: When dealing with thick materials, the pneumatic press arm may not provide enough pressure. The hydraulic version offers greater force and is mounted on the frame, driven by a cylinder and gear reducer motor. It features double pressure wheels that assist in feeding and pulling the material automatically.
4. **Hydraulic Feeding Device**: This device uses a curved surface and guide wheels to make loading and feeding easier. It is particularly useful for large or irregularly shaped materials, ensuring smooth operation and reducing manual effort.
5. **Material Arc Photoelectric Control Device**: Unlike contact-based systems, which can damage the material, photoelectric control uses sensors to detect the material’s arc. This is ideal for non-conductive or high-surface-quality materials, as it avoids physical contact while maintaining accurate control.
