Innovative Points of Automated Rock Wool Production Line

Rock wool sandwich panel is a type of sandwich panel made from rock wool. The rock wool itself is an inorganic fiber board made from basalt as the main raw material, processed at high temperatures, characterized by light weight, low thermal conductivity, heat absorption, and non-flammability. It is a new type of material used for insulation, fire resistance, and sound absorption.

The Importance of an Automated Rock Wool Production Line

Rock wool sandwich panels take full advantage of the unique properties of rock wool core material, exhibiting significant effects in fireproofing, thermal insulation, and sound absorption. They are suitable for steel structure factory roofs, walls, and suspended ceilings and partitions in clean air rooms.

Currently, the production of rock wool sandwich panels is mostly done via manual production lines. Manual production requires two rounds of pressing back and forth, resulting in low production efficiency and high costs. Moreover, the position of the rock wool boards needs to be controlled during production. Manual operations can lead to errors, making it easy for the formed rock wool sandwich panels to not meet the required standards. 

Additionally, after forming, the rock wool sandwich panels need to be transported to a designated location for pressing to ensure quality, but the existing production process is not convenient for this transportation.

To address the inadequacies of existing rockwool sandwich panel production equipment, the importance of an automated rock wool production line cannot be overstated. Highly automated, effective rock wool production lines are very helpful in improving the production efficiency of rock wool boards.

Introduction to the Rock Wool Production Line

The automated rock wool production line utilizes integrated control technology of machinery, electricity, and hydraulics, including PLC control, roll forming, automatic rock wool cutting and conveying, turning and aligning, edge sealing and foaming systems, rock wool adhesive application, polyurethane high-pressure foaming equipment, double-belt machine, double-belt machine temperature control system, automatic stacking, among others.  

The entire rock wool production line process includes: hydraulic decoiler, roll forming rolling mill, automatic rock wool cutting and conveying, turning and aligning, edge sealing and foaming systems, polyurethane high-pressure foaming equipment, double-belt machine, double-belt machine temperature control system, molding band saw machine, soundproof cabins and dust collection devices, conveying roller path, automatic stacking machine, automatic packing machine, among others. The total length of the line is 150 meters. 

Each part of the line adopts network data communication, and the control system manages each unit machine in a decentralized control manner, achieving integrated monitoring, and thereby realizing continuous, fully automated production of polyurethane rock wool composite panels.

Innovations in the Automated Rock Wool Production Line

• The automated rock wool production line achieves the functionality of producing multiple types of composite panels with different core materials on the same equipment, capable of producing polyurethane composite panels, all-rock wool composite panels, polyurethane edge-sealed rock wool composite panels, among other products.

  
  

• Innovations in the continuous production and conveying system for rock wool— the rock wool production line achieves roller conveying, lifting and pushing, strip cutting, 90° turning, and corner aligning of the rock wool panels, thus enabling automated production.

  
  

• The adoption of a polyurethane continuous high-pressure foaming system, controlled by network communication, effectively matches and controls the polyurethane foaming flow rate with the entire line's production speed.

  
  

• The double-belt chain plate adopts a welded structure, installed on an overall welded machine frame, forming a high-strength chain drive system, achieving precision, stability, reliability, and automation during the production and adjustment processes for multiple specification composite panels.

  
  

• Innovations in the band saw cutting system: The rock wool production line utilizes a hydraulic servo system to achieve stable cutting, increased precision and speed, extended saw blade life, and smooth cutting.

  
  

• Comprehensive functionality, ease of operation, user-friendly control system interface, truly realizing integrated control of the machine, electricity, and hydraulics, giving this set of equipment a high degree of automation and good synchronization across all sections.
